Reflex Sympathetic Dystrophy Syndrome

Reflex Sympathetic Dystrophy Syndrome

There are many different types of repetitive strain injuries that one may fall victim to due to overuse of the muscles of bones of the body. Often it is caused due to the strain incurred in the workplace. Most of these injuries can be easily treated with the symptoms eliminated quickly and easily.

Reflex Sympathetic Dystrophy Syndrome – Definition

Reflex sympathetic dystrophy syndrome is a subset of the problem known as complex regional pain syndrome. There are two different types of the complex regional pain syndrome

  • Type 1 – It is known as reflex sympathetic dystrophy syndrome.
  • Type 2 – It is known as causalgia.

Both of these syndromes result in a serious feeling of pain that is experienced by the afflicted individual.

The exact cause of this syndrome is still unknown, but the suspected causes include stress, illness, and injuries. It’s a problem that can strike at any age, but more often than not, people between the ages of forty and sixty are affected.

Both men and women fall victim to the syndrome, but women are more likely to contract it. The syndrome develops near the site of an injury that a person has recently experienced.


Reflex sympathetic dystrophy syndrome sufferers may experience a feeling of intense, burning pain that may in fact spread outside of the original area of injury, sometimes even spreading to the opposite limb of where the injury occurred.

The symptoms of type 1 complex regional pain system include intense feelings of pain near the area of injury which is sometimes accompanied by muscle spasms as well as a lack of mobility in the area. Sometimes, hair and nail growth in the area will increase to a highly noticeable degree.


There are no precise tests that can appropriately diagnose complex regional pain syndrome, and most often, doctors diagnose the syndrome purely off of the symptoms that the afflicted person says that they are experiencing.


There are many methods when it comes to treating the syndrome. Many different drugs may be of merit, including anti-depressants as well as corticosteroids, alpha and beta blockers, and others.

Many patients opt for physical therapy as a means of eliminating the syndrome. Since the pain can be great when one moves the affected area, they often neglect moving it which can actually aggravate the problem. Inactivity can lead to growth of the syndrome.

Most often, Doctors prescribe an injection of an anesthetic in order to treat the problem as a first step. Neurostimulation has also been shown to be of merit, helping to ease the pain of reflex sympathetic dystrophy syndrome by stimulating the spinal cord.

Now that you know more about the problem known as reflex sympathetic dystrophy syndrome, you’ll be better able to diagnose the problem should it affect you.

You may want to consider speaking with a doctor if you experience the symptoms of Reflex sympathetic dystrophy syndrome in order to plan the best course of action for dealing with RSDS.

Ergonomic Eye Problems

Ergonomic Problems of Eyestrain is the most common that most computer users all over the world experience. A number of symptoms associated with Ergonomic problems of eyestrain have been experienced and proved worldwide.

Let’s have a look at some of the symptoms related to vision here:

  1. Visual fatigue
  2. Blurred or double vision
  3. Burning and watering eyes
  4. Headaches and frequent changes in prescription glasses

This is now called under the nickname, computer vision syndrome or C.V.S.

American Optometric Association defines, C.V.S as “A complex of eye and vision Problems which are experienced during and related to computer use”.

There is a basic Ergonomic problems with the prolonged viewing of computer screens. The nature of screen characters and images necessitates subtle but continual refocusing. If one has to regularly switch the attention between a close screen and more distant workspace objects things become more complicated. C.V.S results from this change in dynamics.

Another cause of Ergonomic problems is that the average person blinks approximately 4 times per minute, far less than the natural rate of 22 blinks per minute. This lower blink rate causes eye moisture to evaporate, resulting in a “dry eye” condition . The symptoms of dry eye are sensations such as itching, burning, blurring, heavy eyelids, fatigue and double vision.

There is no evidence yet that computer work causes permanent eye damage. But the temporary discomfort that may occur can reduce productivity, cause lost work time, and reduce job satisfaction and self-confidence of the user.

In most cases eyestrain results from visual fatigue or glare from bright windows or strong light sources, light reflecting off the display screen, or poor display screen contrast.

Methods to Avoid Ergonomic problems: Eyestrain

    1. Give ample exercise to the eyes by periodically focusing on objects at varying distances to avoid Ergonomic Problems of eyes strain
    2. Blink the eyes regularly
    3. Try to keep the air around you moist – For instance, you can use plants, open pans of water or a humidifier (spider plants are said to be particularly good for this and removing chemical vapors from the air)
    4. Adjust the screen height/seating so that while you are comfortably seated, your eyes are in line with the top of the monitor screen
    5. Adjust the brightness control on your monitor for comfort. Focusing on the monitor for a long time with full brightness can cause Ergonomic Problems of eyestrain.
    6. Adjust the contrast on your monitor to make the characters distinct from the background
    7. Adjust the refresh rate of your monitor to stop it flickering
    8. You need to position monitors in order to avoid glare (e.g. not directly in front of windows)
    9. Keep your monitor screen clean to avoid Ergonomic Problems
    10. Keep the screen and document holder (if you use one) at the same distance from your eyes
    11. Try to place the reference materials as close to the screen as possible

You need to service, repair, or replace monitors that flicker or have insufficient clarity

  1. Do regular eye testing at least once every 2 years and more frequently if necessary – especially if you are experiencing eye Problems related to using display equipment. Specify the distance from your eyes to the monitor to your optician and get information regarding special lenses or the use of bifocals.
  2. Wear rigid rather than soft contact lens

Ergonomic Problems : Vision


  1. Reading and/or using a computer causes eyes to tear, itch, or hurt.
  2. Jerky eye movements.
  3. Eyes that cross or turn in or out.
  4. Squinting, eye rubbing, or excessive blinking.
  5. Blurred vision.
  6. Light sensitivity after reading.
  7. Double vision.
  8. Headaches, dizziness, nausea, or fatigues easily after reading.
  9. Head tilting, closing or blocking one eye when reading.
  10. Skips lines or loses place when reading.
  11. Difficulty tracking moving objects.
  12. Misaligning letters or numbers.
  13. Unusual posture or moving head closely to see book or paper.
  14. Avoidance of near work such as reading.
  15. While reading, you feel that words, letters, or lines run together or jump around.
  16. Difficulty concentrating or comprehending reading material.
  17. Persistent reversals of numbers, letters, or words after second grade.
  18. Writes crooked or poorly spaced.
  19. Poor eye hand coordination.
  20. Inconsistent or poor sports performance.

Ergonomics Definition

Ergonomics is the applied science of equipment design, as for the workplace, intended to maximize productivity by reducing operator fatigue and discomfort. The Word ergonomics is taken from the Greek words, “ergon” and “nomos”. Ergos means work and nomos means laws, when combined forms as laws of work.

In the present days Ergonomics definition is given as the science, which deals with designing the job to fit the worker, but not forcing them, to fit the job, from the physical stresses it focuses on joints, muscles, nerves, tendons, bones.

When we define ergonomics in term of science, it is the science of designing products that work in accordance with the way humans think, see, and behave. Products that are compatible with people will dramatically reduce human error, fatigue, discomfort, and stress, and have a profound positive impact on overall end-user performance.

The combined effect of good cognitive and physical ergonomics leads directly to consumer pleasure, fulfillment, and immediate acceptance of the product. Ergonomics reduces learning curves and limits the amount of customer education required for product sell-through.

In total, good ergonomics directly contributes to the success of the product and can be measured quantitatively in terms of customer satisfaction, market share, and profitability. Well-designed products sell. Poorly designed ones do not.

History Of Ergonomics

Ergonomics grew into a distinct scientific discipline during World War II. What began as a form of basic human engineering now encompasses a wide range of disciplines, including psychology, industrial design, medicine, and computer science.

Its practitioners’ range of focus includes concept modeling and product design, job performance analysis, functional analysis, workspace and equipment design, computer interfaces, and environment design.

Characteristics Of Ergonomics

The basis of ergonomics understands the physical and cognitive/perceptual limitations of human performance relative to interaction with products. Such interface analysis is crucial to establishing a safe and effective system of operation for the user.

Cognitive Ergonomics

Proper fit of a product to a user does not end with physical interfaces. The perceptual and cognitive demands that a product places on the user must also be examined. Note that a great misconception regarding these areas of human functioning is that they relate to emotive – and therefore qualitative – responses of users.

But rather, both perceptual and cognitive behaviors offer fact-based, quantitative data that can be used in product development.

Physical Ergonomics

A thorough understanding of the physical characteristics of a wide range of people is essential in product development. When analyzing design relative to human performance, ergonomists study anthropometric data, which includes size percentiles of a wide range of populations defined along such lines as gender and age.

Ranges of joint motions, strengths, and grips for various populations are also reviewed. These data serve as valuable information to designers and help ensure that the final product will physically fit the targeted endusers.

Ergonomic Problems

Ergonomic problems can be caused by both work-associated and non-work associated conditions can either individually, or by both interacting with each other.

There are many ways to determine which is conditions of workplace can lead to Ergonomic Problems. The main risk for Ergonomic problems like Repetitive Strain Injury and Carpal Tunnel Syndrome are the frequent repetitive motion tasks, awkward posture, vibrations, forceful movements, stress at workplace, poor workplace setup.

Symptoms of Ergonomic Problems

  1. Pain in wrists, forearms, elbows, neck, or back followed by discomfort
  2. Aching or tingling
  3. Dry, itchy, or sore eyes
  4. Loss of color in affected regions
  5. Blurred or double vision
  6. Cramping
  7. Numbness or a burning sensation in the hand
  8. Reduced grip strength in the hand
  9. Swelling or stiffness in the wrist joints
  10. Reduced range of motion in the shoulder, neck, or back
  11. Weakness
  12. Tension stress headaches and related ailments

The main causes of are:

  1. Awkward posture
  2. Frequent repetitive motion tasks
  3. Stress at workplace
  4. Vibrations
  5. Forceful movements
  6. Poor workplace setup
  7. Sitting in same posture for continuous long hours
  8. Lower back support is inadequate

Types of Ergonomic Problems

  1. Musculoskeletal Disorders
  2. Ergonomic Problem-Eye
  3. Repetitive Stain Injury
  4. Carpal Tunnel Syndrome
  5. Other Ergonomic Problems

Office Ergonomics Information

  1. Try to vary your tasks and Office Ergonomics, so that you get ample time to recover from the outcome of your activity. Different ways are being practiced to provide recovery time for overused muscles.
  2. Design your Ergonomic Office in such a way that you can easily change your working postures according to your convenience. It is always safe to select adjustable furniture for the workstation that allows you to shift to different seated postures every time you want to. This helps different muscle groups to provide support while others rest.
  3. Your work area should be spacious enough to let you use the mouse with either hand alternately. Thus the tendons and muscles of the free hand get enough relaxation.
  4. Reduce your dependence on the mouse and use more of shortcut keys. For example, you can use Ctrl+S to save, Ctrl+P to print etc. Certain jobs do require more dependence on the mouse. Users in such professions should learn to use more shortcut keys.
  5. Jobs that involve more repeated tasks or prolonged static postures may lead to muscular strain. The users should forcefully take several short breaks or relaxed pauses. The users should stand, stretch, and move around during such breaks. This increases blood circulation and gives enough time for the muscles to relax.
  6. Try to mix computer tasks and non-computer tasks alternately in all possible situations. T his encourages the movement of different parts of the body by using different muscle groups.

Office Ergonomic Disorder-Medical Awareness and Training

Probable Risks of Office Ergonomics Disorder

Most of the users neither get a chance to go through a proper training to identify the risks and hazards of Office Ergonomics nor do they realize effective work practices designed to reduce these hazards of Office Ergonomics. Such people have more chances of getting affected because of their ignorance.

Even though disorders like Ergonomic problems affect them, they are not medically aware of the signs and symptoms and hence do not notice or address such issues. For instance, users who don’t realize the hazards of awkward postures while working on the computer don’t know how to take care of their pains and strains. Delay in realizing and diagnosing such discomforts may lead to severe injury.

Feasible Solutions of Office Ergonomics Disorder

Everybody who uses computers is bound to acquire training on general Office Ergonomics awareness based on the following issues:

  1. They should get trained on the aspects related to all the computer components exclusively, that generally increase discomfort or risk of injury
  2. They should be made aware of the different signs and symptoms of all kinds of discomforts caused by continuous computer usage so that they can identify these from the beginning and treat with appropriate medications.
  3. They should be given enough information on the methods of using and adjusting all the computer components correctly as well as the environmental factors.

Review of GentleMouse 1.0

GentleMouse is a patent-pending, ergonomic software tool that clicks the mouse for you! GentleMouse is perfect for anyone with disabilities or limited hand movement, suffering from or at risk of developing Repetitive Strain Injury (RSI), or just tired of having to constantly click the mouse.

GentleMouse is a great complement to ergonomic mice and alternative pointing devices.

How does it work? 
Whenever you move and pause the mouse cursor, GentleMouse briefly displays a small, transparent window next to the cursor called a Trigger Window.

If you want to click where you stopped, you just move and stop the mouse over the Trigger Window, and GentleMouse simulates the click for you. It’s that easy! No clicking. No strain. No pain.

There are secondary Trigger Windows that become visible when you move through the first Trigger Window corresponding to right-click, double-click, and middle-click, as well as common keyboard shortcuts (copy, cut, paste, etc.) and browser shortcuts (home, forward, back, etc.).

So you can perform all the mouse actions and much more all without clicking the mouse. GentleMouse is fully customizable. You can assign up to many mouse commands and keyboard shortcuts to the Trigger Windows.

You can also adjust how fast the Trigger Windows appear, how long they stay visible, and how fast the mouse or keyboard action is simulated. You can change the Trigger Windows’ size, text, color, transparency and more. You can even choose to have images represent the different mouse or keyboard actions.

With GentleMouse, you can still click manually if you want to. So you can choose to never click the mouse or let GentleMouse do most of the clicking. Either way, by reducing clicking, GentleMouse may lower your risk of developing RSI or other injuries associated with clicking.

Ergonomics for Children

In the present world of computers, child ergonomics is basic thing to be thought to child. Kids must pay attention to child ergonomics because they usually are working on equipment that is too big for them.

Children who use computers and other technology poorly can end up with eye strain, carpal tunnel and back problems. No matter how old a child is, preventing computer-related disorders is much easier than treating them after they strike. You can design children’s computer work areas with ergonomics in mind and teach kids good habits that will stick with them.

Providing schoolchildren with adjustable ergonomic furniture not only helps avoid long-term damage to young bones, but also teaches them to take an interest in their occupational health as future adult workers.

Although computers are now commonplace in classrooms that accommodate children as young as four, little consideration had so far been given to the effects of workstation design in the classroom. For this reason schools should adopt child ergonomics policies that minimize the risk of physical damage from computers.

Children’s use of the computer has increased tremendously. To meet the requirements of young users, manufacturers are re-designing ergonomics computer desks. The main requirement of a child’s computer desk is the lower height. It should also be comfortable for the child to work on.

The main aspect in designing special computer desks for children is child ergonomics. Monitors should be at eye-level to reduce neck and eye strain. The keyboard and mouse should also be placed at the ideal height to make it more comfortable.

Child Ergonomics Tips

  • Position the monitor’s screen at or below the child’s eye level. Take the monitor off its base or have the child sit on phone books to reach the desired height.
  • Because most office chairs are too big for children, use a back cushion, pillow or rolled-up towel for back support.
  • The child’s feet should be placed on a box or footstool for comfort. Feet dangling over the chair’s edge can impede circulation.
  • If children and adults in your home share the same computer workstation, make certain that the workstation can be modified for each child’s use.
  • Wrists should be held in a neutral position while typing — not angled up or down. The mouse surface should be close to the keyboard so your child doesn’t have to reach or hold the arm away from the body.
  • The child’s knees should be positioned at an approximate 90- to 120- degree angle. Feet can be placed on a foot rest, box, stool or similar object.
  • Reduce eyestrain by making sure there is adequate lighting and that there is no glare on the monitor screen. Use an antiglare screen if necessary.
  • Limit your child’s time at the computer and make sure he or she takes periodic stretch breaks during computing time.
  • Your child’s muscles need adequate hydration to work properly and avoid injury. Encourage your child to drink four 8-ounce glasses of water a day. Carbonated beverages, juices and other sweet drinks are not a substitute.

Ergonomic Computer Monitors

Positioning your Ergonomic Monitor to a Perfect height and distance that is comfortable for you with an Ergonomic Monitor arm or lift mechanism. Most of your time is spent looking at the Ergonomics Monitor. Hence, utmost care should be given in choosing and appropriately placing it in your workstation.

Suitable positioning of the Ergonomic Monitor would help you reduce exposure to compelling exertions, inept postures, and overhead glare. Possible health issues like extreme exhaustion, eyestrain and related disorders like itching, sty, and power. Variations of the eye lens, and neck and back pain can be avoided on proper selection of the Ergonomic Monitor. The positioning of the Ergonomic Monitor should be in concurrence with the other components like the keyboard, desk, and chair.

While using the Ergonomic Monitors , ensure the following:

  • Ensure that the Ergonomic Monitor is in front of you and at least 20 inches away.
  • Ensure that the top line of the screen of the Ergonomic Monitor is at or below your eye level.
  • Ensure that the Ergonomic Monitor is placed perpendicular to the window.

The viewing distance, viewing time, viewing angle, and viewing clarity have to be adjusted to get the best results without affecting your health.

Ergonomic Monitor : Viewing Distance

Probable Risks

  • You tend to lean forward or move backward thus positioning yourself awkwardly to have a better view of the monitor. Ensure that the monitors are neither too close nor too far so as to strain your eyes.
  • Viewing distance longer than the normal: When you lean forward to view the monitor better, you are straining your eyes as well as your torso. Your backbone doesn’t get any support that causes severe pain on your shoulders and the back.
  • Viewing distance shorter than the normal: There is a tendency to move backward for better focus which in turn causes convergence problem to your eyes. Also you may tend to tilt your head backward or push yourself away from the monitor in which case you may have to outstretch your arms to do the typing. This may cause pain in your arms, fingers, wrist, and elbow.

Feasible Solutions

  • Position yourself at a secure distance from the Ergonomics Monitors wherein you can read all text without straining your eyes. Ensure that your head and torso are straight and your chair is firmly supporting the back. Ophthalmologists usually recommend a safe viewing distance between 20 and 40 inches (50 and 100 cm) from the eye to the front surface of the computer screen. If you still feel difficulty reading the text, do increase its font size.
  • There should be ample desk space between the user and theErgonomic Monitor (table depth). If the desk space is not enough, here are some tips:
  • Pull the desk away from the wall or the divider thus giving more space for the back of the Ergonomic Monitor.

2) Normally flat-panel displays are used which requires less desk space and are not as deep as the conventional monitor.

3) In order to make a deeper working surface, you can try installing an adjustable keyboard tray.

  • Always remember to adjust the viewing distance between 20 and 40 inches.
  • Flat-panel displays do not consume as much space as the conventional monitors

When you work in front of your computer for long hours with your head and neck turned to one side, you are sure to increase fatigue and pain in your neck muscles.

Feasible Solutions

  • While working on your computer, your head, neck, and torso should face forward and hence you need to be careful about positioning of the Ergonomic Monitor . The ideal position is to place it directly in front of you. But, if that is not possible every time, the maximum tilt recommended is 35 degrees to the left or right.
  • If your work is chiefly involved with printed matter, it will be ideal to place the Ergonomic Monitor a little to the side with the printed matter just in front of you. The distance between the Ergonomics Monitor and the printed matter should be minimal.

Probable Risks

Ergonomic Monitors that are placed too high or too low are not recommended for people who have to use computers for long hours per day. It affects the head, neck, shoulders, and the back, as they have to adjust their positions for better view of the Ergonomics Monitors. In the long run, the muscles that support the head are fatigued due to these awkward postures.

Feasible Solutions
  • Ensure that the top part of the Ergonomic Monitor is either at the same level of your eyes or slightly below it. Also, the center of the Ergonomic Monitor should be located 15 to 20 degrees below horizontal eye level.
  • The entire visual area of the display screen should be located so that the downward viewing angle is never greater than 60 degrees when you are in any of the four reference postures. While in the reclining posture, the straight forward line of sight will not be parallel with the floor. This would increase the downward viewing angle. Also, very large Ergonomic Monitors increase the angle.
  • Do not to place the Ergonomic Monitor above the other equipments like CPU or surge protector. The monitor would be too higher than your eyes that may increase the strain of your eyes, neck, and back.
  • The chair can be raised to lift your line of sight. Ensure that your feet get good support and your thighs can move freely under the desk.

Probable Risks

Those who use bifocal lenses normally view the monitor through the bottom portion of their lenses. In such case, they automatically tilt their head backward to have a better view of the monitor. And if the monitor is placed too high, the muscles that support their head easily get fatigued.

Feasible Solutions

The Ergonomic Monitor can be lowered to avoid any kind of strain to the neck and eyes. The screen can be tilted a little upward for convenience.

Ergonomic Monitor : Bifocal Lenses Cause Stress

  • The user is supposed to raise the height of the chair until the Ergonomic Monitor can be viewed without having to tilt the head backwards. A footrest can be used and the keyboard can be raised a little for convenience.

Good single-vision lenses are available in the market with focal lengths designed for working in the computer. Viewing theErgonomic Monitor through the bottom portion of the lens can be avoided by using a pair of this single-vision lens.

Ergonomic Monitor: Viewing Time :

Probable Risks

If you view the monitor continuously for long hours without taking breaks, your eyes become dry and exhausted easily. You tend to blink less while working for long hours.

Feasible Solutions

  • Give rest to your eyes every so often by focusing on objects that are at a considerable distance from your seat like a painting on the wall around 20 feet away.
  • Periodically wet your eyes by blinking and looking at distant objects.
  • You tend to slow down in your work if you keep working for long hours on the computer. The ideal solution would be to take breaks in between and attend to other non-computer works like filing, making calls, or interacting with your customers. This gives good rest to your eyes.

Ergonomic Monitor: Viewing Clarity

Probable Risks

Do not tilt monitors considerably either toward or away from the operator, as the objects on the screen may appear distorted making them illegible. And if the monitor is tilted back, there are chances of the overhead lights creating glare on the monitor. You tend to sit in different unhealthy positions to get a better view of the screen hence straining your eyes and the back.

Feasible Solutions

  • You can tilt the monitor somewhere between 10 to 20 degrees so that it is perpendicular to your line of sight. For this purpose, it is better to have a riser/swivel stand. If this is not possible, you can tilt the Ergonomic Monitor back slightly by placing a book under the front edge. But to avoid glare in this case, do use a glare screen.
  • Ergonomic Monitors support surfaces should be user friendly by allowing the user to modify viewing distances and tilt and rotation angles.

Probable Risks

If the image that you view on the screen is of poor quality, your eyes have to strain more to view it properly. The distorted images may be due to electromagnetic fields caused by other electrical equipment located near computer workstations or due to dust accumulation. This is often accelerated by magnetic fields associated with computer monitors and can reduce contrast and degrade viewing conditions.

Feasible Solutions

  • Those equipments with electrostatic potentials more than +/- 500 volts should be kept away from your workstation.
  • Ensure that the monitor is dust free while in use.

Ergonomic Monitor Recipe:

1 . Always ensure that the screen is large enough for sufficient visibility. It is acceptable to use a 15 to 20-inch Ergonomic Monitor . If the unit is very small, you will find it difficult to read the characters. If the unit is very large, you may require too much space.

2 . Always ensure that the angle and tilt of the Ergonomic Monitor can be adjusted without much effort.

3 . For workstations with limited space, flat panel displays are preferred as they take less room on the desk.


Ergonomic Mouse

Ergonomic Mouse or the pointing device is now available in the market in different sizes, shapes, and configurations. Apart from the conventional Ergonomic Mouse, other pointing devices include touch pads, trackballs, fingertip joysticks, and pucks. While designing a safe workstation, you should give great importance to selection and positioning of Ergonomic Mouse/Pointer. Do keep in mind the following factors while evaluating your workstation.

  • Ergonomic Mouse Placement
  • Ergonomic Mouse Size, Shape, and Settings

Ergonomic Mouse Guidelines

  • Ensure that the Ergonomic Mouse/Pointer is close to the keyboard.
  • Ensure that you use alternate hands while handling theErgonomic Mouse/Pointer.
  • Learn and use the keyboard short cuts to reduce extended use of Ergonomics Mouse.

Ergonomic Mouse Placement:

Probable Risks

If the Ergonomic Mouse/Pointer is not placed near the keyboard, there are chances that your body will be exposed to awkward postures, contact stress, or forceful hand exertions while operating the device. If you continue to work in such postures for long hours, your shoulders and arms will be stressed out. For convenience you might sit with awkward wrist and shoulder postures that might lead to Ergonomic problems in the long run.

Feasible Solutions

  • Select a particular position for the Ergonomic Mouse/Pointer so that you can maintain a straight, neutral wrist posture. If required, you may make slight adjustments in your chair, desk, keyboard tray, etc.
  • If the keyboard tray/surface that you use does not have enough space for both the keyboard and the mouse, you can try out the following suggestions:
  • You can use Ergonomic Mouse platform over the keyboard that helps you to use the Ergonomic Mouse above the 10-key pad.
  • You can set up a Mouse Ergonomic tray next to the keyboard tray.
  • You can se a keyboard that has a pointing device, such as a touch pad, incorporated into it so that the work gets done even without the help of the Mouse Ergonomics.
  • You can try using a keyboard without a ten-key pad, which leaves more room for the Ergonomic Mouse/Pointer.
  • You can install keyboard trays that are big enough to accommodate both the keyboard and Ergonomic Mouse.
  • You can try a Ergonomic Mouse pad with a wrist/palm rest to promote neutral wrist posture.
  • You can substitute keystrokes hence depending less on the mouse, such as Ctrl+S to save, Ctrl+P to print etc.

Ergonomic Mouse: Size, Shape, and Settings

Probable Risks

If the size and shape of the pointers that you choose are unsuitable, it may force you to sit in awkward postures, thereby increasing stress and hence overexertion. Generally, pointing devices that are too big or too small make the fingers to apply more force and bend the wrist to awkward positions. Also, if you operate a device designed for the right hand with your left hand, it leads to posture disorders that can create contact stress to the soft tissue areas in the palm of the hand. Contact stress leads to irritation and inflammation.

Feasible Solutions :

  • An Ergonomic Mouse is to be selected to the fit the hand of the user who will be using it mostly.Ergonomic Mouse to fit right and left hands as well as small and large hands are available in the market. It is ideal to select a Ergonomic Mouse that is designed for either hand because you can switch from one hand to the other while operating the device hence giving rest to one hand at a time. Before selection of the Ergonomic Mouse, it is better to test it and ensure proper fit and feel.
  • The size of the Ergonomic Mouse matters and hence while selecting you need to ensure that you have to apply only a minimum force to generate movement. Normally puck devices should be small in size for using with single hand with a width of 1.5 to 2.5 inches, length of 2.5 to 4.5 inches and a height of 1 to 1.5 inches.
  • It is better to reduce your dependence on the Ergonomic Mouse by using short cut keys and other options available on the keyboard like page down thereby reducing the strain on hands.
  • Try out other pointing devices like joystick, touch pad, or trackball that fits your hand better and doesn’t require bending the wrists when you grip the device. Remember to try out new products prior to selection and long-term use.

Ergonomic Mouse wrist / palm rest makes the positioning of the hand over the keyboard comfortable.

Probable Risks

If the sensitivity of the input device is not set properly, you tend to use more force and awkward hand postures to control it. For example, a very sensitive mouse may require excessive and extended finger force for good control. If the sensitivity of the mouse is not enough, you need to deviate the wrist in a wider angle to move the pointer to your desired place. When you exert your wrist forcefully for a long time or bend it repeatedly to place the pointer, your hand and arm muscles get fatigued increasing the risk of Ergonomic injuries.

Feasible Solutions

  • The speed of the Ergonomics Mouse pointer may be defined as the pace in which it moves on the screen when you move the Ergonomic Mouse with the hand. The Ergonomic Mouse, that you select should be sensitive and fast enough so that you can comfortably adjust and control it as required. Also, the pointer should cover the entire screen of the monitor while your wrist is relaxed in a straight, neutral posture.
  • In order to control the Ergonomic Mouse /pointing device with a light touch without straining your wrist, it is better to set its sensitivity. Devices in which the sensitivity can be adjusted through the computer control panel are now available in the market.
  • Do not grip the Mouse Ergonomics device tightly in order to get good control of it.

If you are using a trackball, ensure that its exposed surface are is not less that 100 degrees. It has to comfortably rotate in all directions for the user to try any combination of movement as required.

  1. The Ergonomic Mouse /Pointing device should be selected based on the requirements of your job and your physical restrictions. Other than preference, there is no much difference between a Ergonomic Mouse, trackball, and other pointing devices.
  2. The cord of the Ergonomic Mouse should be long enough to be conveniently placed near the keyboard. The shape and size of the Ergonomic Mouse should be good enough to snug into the curve of your hand.
  3. Among the different Ergonomic Mouse, if you prefer a trackball for your work, remember not to select the ones that need your thumb for rolling its ball. This can cause discomfort and possible injury to the area around your thumb.
  4. If the user’s hands are small, then select a mouse that is smaller than the normal ones. But if multiple users are using it, then a normal-sized one should be retained.
  5. Always go for a mouse that has good sensitivity adjustments and that can be used by both hands conveniently.

Ergonomic Mouse: Wrist/Palm Supports

Fig. 12 – Palming the Ergonomic Mouse makes the wrist straight.

If your keyboard and Ergonomic Mouse are arranged properly and appropriately, then you can say that your workstation is a comfortable and productive one.

This comfort is intensified if you use wrist or palm rests. If used properly, wrist/palm supports reduce muscle activity while working on the computer and facilitates neutral wrist angle.

Ergonomic Mouse: Wrist Rest Guidelines

To keep the contact stress that can occur while typing and while using the mouse to a minimum, it is better to use a wrist rest so that you can maintain straight wrist postures.

Probable Risks
  • The wrists tend to bend in a wider angle if you use the keyboard for long hours without using a wrist rest. As the angle of bend increases, the contact stress and irritation on tendons and tendon sheathes also increases. Professionals who depend more on keyboards to get their job done have to be very careful. The contact stress between the wrist of the user and the hard/sharp components in the workstation also increases.
  • The motion of the wrist is slowed down while you are resting the wrist/palm on a support during the typing jobs that will in turn lead to awkward wrist postures.
Feasible Solutions
  • Ensure that your hands are moving freely and are raised above the Ergonomics Mouse wrist/palm rest while using the keyboard. Also remember that the pad should be in touch with the palm of your hand and not your wrist while resting on the Ergonomic Mouse wrist rest.
  • Ensure that these are part of a well-designed workstation.
  • Do not frequently bend your wrists by adjusting other workstation components like that chair, desk, or the keyboard. See to it that your wrists are in a straight, neutral posture.
  • The Mouse Ergonomics wrist support should be matched with the width, height, and slope of the front edge of the keyboard.

The Ergonomic Mouse wrist/palm supports should be fairly soft and rounded to minimize pressure on the wrist. Ideally it should be at least 1.5 inches (3.8 cm) deep.

Ergonomic Mouse: Wrist Rest Recipe

  1. The shape, width, slope, and height of the Ergonomic Mouse wrist rest should match the front edge of the keyboard.
  2. It would be better to use gel type materials for the padding that makes it soft and firm.
  3. The recommended depth of the Ergonomic Mouse wrist rest is at least 1.5 inches (depth away from the keyboard). This helps to minimize contact pressure on the wrists and forearm.

Keyboard Tray for Ergonomics

Ergonomic keyboard tray is attached underneath the desk, which allows you to adjust the height and position of the keyboard to a comfortable position. It is specifically designed to adjust the height and angle of the keyboard to provide a comfortable posture to the user.

Many ergonomic keyboard trays also included with an ergonomic mouse tray. An ergonomic will provide you a better viewing angle of the monitor.

Ergonomic Keyboard Tray tips:

1. While adjusting the ergonomic keyboard tray, the best height for the keyboard is at elbow height or lower.

2. The ergonomic keyboard tray should position the keyboard to be at approximately the same angle as your forearm.

3. Area for a wrist rest

4. Area for a mouse

Ergonomic Keyboard Tray Recipe:

1. Ensure that your Ergonomic Keyboard tray has adjustment mechanisms that lock into position without having to turn knobs. These are frequently over tightened, which can lead to stripped threads, or they may be difficult for some users to loosen.

2. The width and depth of the Ergonomic Keyboard trays should be large enough to accommodate the keyboard and any secondary devices, such as a mouse.

3. The minimum vertical adjustment range (for a sitting position) should be 22 inches to 28 inches from the floor, if you are working in the sitting position using the Ergonomic Keyboard tray.

Ergonomic Keyboard Tray Disadvantages:

1. The keyboard tray reduces knee clearance.

2. Keyboard trays can be adjusted too low, too high, or at the wrong angle, causing bent wrists.

3. Keyboard tray can only provide enough space for just keyboard and if the mouse tray is also included in it, if will be a forced long reach to use a mouse.

Ergonomic Keyboard

Ergonomic Keyboard which are available in the market today, mostly are split keyboards. These Ergonomic Keyboardmainly solve the problems related to wrist ulnar deviation (hand deformity, seen in chronic rheumatoid arthritis and lupus erythematosus, in which the swelling of the metacarpophalangeal joints causes the fingers to become displaced to the ulnar side).

      There is no research available to prove that split keyboards can solve this problem. For most people a regular keyboard works well if they use the keyboard placed in the proper position and for some people, a split type of Ergonomic Keyboard do better than a traditional keyboard, but if you are a split type Of Ergonomic Keyboard, make sure that it is not causing you any problems.

      The procedure of selection and arrangement of the Ergonomic Keyboard plays a vital role in decreasing ergonomic problems. When designing a computer workplace, you should remember certain vital factors like the height of the keyboard, its distance from you, and the usage. You should choose a perfect Ergonomic Keyboard and find a proper place matching with the other components like the pointer/mouse and wrist/palm rests.

Ergonomic Keyboard Guidelines

  • Ensure that the Ergonomic Keyboard is placed directly in front of you.
  • Ensure that the elbows are close to your body and the shoulders are in relaxed position.
  • Ensure that your wrists are straight and in -line with your forearms.

Ergonomic Keyboard Placement – Height:

Probable Risks:

You tend to keep your shoulders, arm, and wrist in awkward positions if the Ergonomic Keyboard, pointing devices, or working surfaces are placed too high or too. Normally, your wrists bent up when the Ergonomic Keyboard are placed too low and you raise your shoulders to elevate your arms when the keyboards are placed too high. Such kind of awkward postures may lead to discomfort of the wrist, hand, and your shoulder.

Feasible Solutions

  • To maintain Ergonomic seating, the height of the chair and the work surface need to be adjusted. Your elbows need to hang comfortably to the side of the body with the height almost same as the Ergonomic Keyboard. The shoulders need to be in relaxed position and ensure that your wrists do not bend up or down or to either side while you are using the Keyboard Ergonomics.
  • Ensure that the thickness of your work surface is not more than 2 inches.
  • Good Ergonomic Keyboard trays with adjustable height and tilt giving enough space for leg and foot along with adequate space for other input devices like Ergonomic Keyboard and pointer/mouse are available in the market if you find it difficult to adjust your work surface or your chair. While selecting a Ergonomic Keyboard tray, ensure that it has all the mentioned features
  • The vertical position of the Ergonomic Keyboard should be maintained within the recommended range. Its tilt can be raised or lowered using the keyboard feet to maintain straight, neutral wrist postures while making slight changes in arm angles.

Ergonomic Keyboard Placement – Distance:

Probable Risks

A keyboard user is forced to assume awkward postures such as reaching with the arms, leaning forward with the torso, and extreme elbow angles if the keyboard or pointer/mouse is placed too close or too far away from him. Studies have shown that such awkward postures generally lead to ergonomic disorders of the elbows, shoulders, hands, and wrists.

Feasible Solutions:

  • Ensure that the Ergonomic Keyboard is placed directly in front of you at a distance that keeps your elbows close to your body with the forearms approximately parallel with the floor.
  • If the armrest of your chair doesn’t allow sitting in a comfortable position or if your desk space is small, you can use a Ergonomic Keyboard tray.

Design and Use:

Probable Risks

While using a traditional keyboard, you may have to bend your wrists sideways to reach all the keys. When you extend the legs on the back of the keyboard, you tend to bend your wrist upward causing a keyboard tilt. The keyboards of the laptop computers that are comparatively smaller than the normal ones also force the user to sit in awkward positions. This in turn leads to contact stress to the tendon sheath and tendons that must move within the wrist during repetitive keying.

Feasible Solutions

  • Adjust the height of the Ergonomic Keyboard or chair to attain a neutral wrist posture thus reducing the awkward wrist angles.
  • The user may even elevate the back or front of Ergonomic Keyboard to achieve a neutral wrist posture. Normally, if the user is sitting in a position lower than that of the keyboard, a slight elevation made to the back of the Ergonomic Keyboard would help maintain a neutral wrist. Similarly, if the user is typing with the Ergonomic Keyboard in a lower position, raising the front of the Ergonomic Keyboard may help maintain neutral wrist postures. If the Ergonomic Keyboard feet tend to increase the bending of the wrist, do not use it.
  • You can sit with neutral wrist postures by taking into account alternative Ergonomic Keyboard. These can be provided on a case-by-case basis. It takes time to get used to such mechanisms. Though alternative Ergonomic Keyboard help the users to maintain neutral wrist postures, studies have not yet provided enough information regarding its capability to avoid discomfort and injury.
  • The size of the Ergonomic Keyboard and spacing of the keys should be of appropriate size to suit majority of the customers. The recommended spacing between the centers of two keys horizontally is 0.71-0.75 inches (18-19 mm) and vertically is 0.71-0.82 inches (18-21 mm).

Ergonomic Keyboard Recipe

  1. You can maintain neutral wrist postures by using split type of Ergonomic Keyboard.
  2. Ergonomic Keyboard with more adjustability options are often better than the others to maintain neutral wrist postures. There are Ergonomic Keyboards with adjustable feet that can accommodate a wider range of Keyboard Ergonomic positions and angles. Ergonomic Keyboard with adjustable feet on the front as well as the back will further aid adjustments.
  3. Ensure that the cord connecting the Ergonomic Keyboard and the CPU has ample length to let the user place both these components in a variety of convenient positions in the workstation. The recommended cord length is around six feet.
  4. Consider an Ergonomic Keyboard without a 10-key keypad if the task does not require one. If the task does require one occasionally, an Ergonomic Keyboard with a separate 10-key keypad may be appropriate. Ergonomic Keyboard without keypads allow the user to place the mouse closer to the Ergonomic Keyboard.
  5. If you prefer to work with the Ergonomic Keyboard tray, ensure that the size and shape of the keyboard matches with that of the tray.
  6. It is always better to buy separate wrist rests than going for Ergonomic Keyboard with built-in wrist rest.
  7. If you have to work for prolonged hours with Ergonomic Keyboard, detach them from the display screen. Do not use laptop for long hours of typing jobs.

Ergonomic Keyboard Tray Recipe

  1. The width and depth of the Ergonomic Keyboard trays should be large enough to accommodate the keyboard and any secondary devices, such as a mouse.
  2. The minimum vertical adjustment range (for a sitting position) should be 22 inches to 28 inches from the floor, if you are working in the sitting position using the Ergonomic Keyboard tray.
  3. Ensure that your Ergonomic Keyboard tray has adjustment mechanisms that lock into position without having to turn knobs. These are frequently over tightened, which can lead to stripped threads, or they may be difficult for some users to loosen.

Ergonomic computer keyboard is the solution to the Repetitive strain injury and Carpal tunnel syndrome. It is a typist friendly keyboard. An ergonomic computer keyboard was designed as a solution to the poor postures and the wrists, hands, shoulders and neck problems, which are contributed by the traditional keyboard.

Ergonomic computer keyboards tries to reduce the repetitive motions by changing the shape. The two major types of ergonomic computer keyboards available in the market are the Vertical type of ergonomic computer keyboards and Split type of ergonomic computer keyboards.

An ergonomic computer keyboard allows the shoulders of the user to be in a comfortably relaxed position. It even allows placing the wrist in a comfortable position. An ergonomic computer keyboard allows all the fingers, including the little finger to make extension and flexion movements.

There is no research available to prove that split keyboards can solve this problem. For most people a regular keyboard works well if they use the keyboard placed in the proper position and for some people, a split type of Ergonomic Keyboard do better than a traditional keyboard, but if you are a split type Of Ergonomic Keyboard, make sure that it is not causing you any problems.

When designing a computer workplace, you should remember certain vital factors like the height of the keyboard, its distance from you, and the usage. You should choose a perfect Ergonomic Keyboard and find a proper place matching with the other components like the pointer/mouse and wrist/palm rests.

Ergonomic Computer Keyboard Guidelines:

  • Ensure that your wrists are straight and in -line with your forearms.
  • Ensure that the Ergonomic Keyboard is placed directly in front of you.
  • Ensure that the elbows are close to your body and the shoulders are in relaxed position.

Ventilation for Ergonomics

Ventilation Ergonomics is to be followed at a workstation otherwise it may lead to discomfort to the workers of the workplace

Ventilation Ergonomic – Probable Risks:

  1. If the ventilation system is poorly designed or not functioning properly, the user may experience discomfort. For instance, air conditioners or heaters that directly “dump” air on users are bad for health.
  2. Your eyes tend to get dried easily due to the dry air, especially if you are wearing contact lenses.
  3. If the air circulation in the room is poor, it can result in stuffy or stagnant conditions.
  4. Your comfort and hence the productivity is affected if the t emperatures are above or below standard comfort levels.

Feasible Solutions:

  1. If the air conditioning vents in your workplace are not designed to redirect the flow of air away from the underneath areas of the vents, try not to place desks, chairs, and other office furniture in these areas.
  2. In order to redirect and mix airflows from ventilation systems, you can use diffusers or blocks.
  3. Try to k eep the airflow rates within three and six inches per second (7.5 and 15 centimeters per second). In fact, these airflow rates are barely noticeable or not noticeable at all.
  4. The relative humidity of the air should be maintained between 30% and 60%.
  5. During hot season, try to maintain the ambient indoor temperature between 68° and 74° F (20° and 23.5° C). During cold season, the recommended temperature is between 73° and 78° F (23° and 26° C).

Probable Risks

The users will have discomfort and several health problems if they are exposed to chemicals, volatile organic compounds (VOCs), ozone, and other particles from computers and their peripherals (say, laser printers).

Feasible Solutions

  1. Before purchasing a computer and its components, do investigate about its potential to emit air ventilation diffuser pollutants. The components that are identified to emit pollutants should be placed in well-ventilated areas in your office..
  2. You need to ensure sufficient supply of fresh air to m aintain proper ventilation in your office room.
  3. Before installing the new equipments, you must a llow them to “air out” in a well-ventilated area.

Monitor Contrast for Ergonomic Lighting

Probable Risks:

You may be affected with headaches and eye fatigue if the contrast between light and dark areas of the computer screen are high.

Feasible Solution:

  1. It is recommended to use well-distributed diffuse light for your workstation. The advantage of diffuse lighting is that
    • The visual field has very few spots (or glare surfaces) in the visual field, and
    • The contrasts created by the shape of objects become softer.
  2. Use light, matte colors and finishes on walls and ceilings for better reflection of indirect lighting and reduce dark shadows and contrast.

Ergonomics Lighting- Glare:

Probable Risks (1)

The sources of direct light like windows and overhead lights that cause reflected light to show up on the monitor make images more difficult to see, resulting in eyestrain and fatigue.

Feasible Solutions

  1. The display screen should be p laced at right angles to windows and light sources. The task lightings like the desk lamp should be placed in such a way that the light does not reflect on the screen.
  2. You should clean the monitor frequently by wiping with a clean and dry cloth. A layer of dust can add to glare.
  3. You can help reduce the glare by using blinds or drapes on windows.
    Note: V ertical blinds work best for east/west facing windows and horizontal blinds for north/south facing windows.
  4. You can attach glare filters directly to the surface of the monitor to reduce glare. Take care that these filters do not significantly decrease screen visibility. In order to redirect lighting, you can install louvers, or “egg crates” in overhead lights.
  5. To reduce glare from overhead lighting, you can u se barriers or light diffusers on fixtures.

Probable Risks (2)

The users may suffer from discomfort, annoyance, or loss in visual performance and visibility due to the reflected light from polished surfaces such as keyboards.

Feasible Solutions

You can paint your walls and work surfaces to limit reflection around the screen. Use a medium colored, non-reflective paint. Arrange workstations and lighting to avoid reflected glare on the display screen or surrounding surfaces.

Note: It is noticed that a few number of high-powered lamps will minimize glares than a large number of low powered lamps.

  • You can slightly tilt down the monitor to prevent it from reflecting overhead light.

The computer monitor can be adjusted for dark characters on a light background. This reduces the reflection compared to the light characters on a dark background.

Ergonomic Lighting

Ergonomic Lighting is a very important aspect of a healthy working environment.

Do not take this section lightly, no pun intended!

  1. The Ergonomic Lighting at your workstation depends on the type of job you are involved in. Do use bright lights with a large lighted area while working with printed materials. Limit the brightness of light for computer tasks.
  2. The user should be able to adjust the position and angle of the light sources, as well as their intensity levels.
  3. To direct or diffuse the light, it should have a hood or filter.
  4. The base of the light should be large enough to allow a variety of convenient positions or extensions.

Ergonomics Lighting- Monitor Brightness:

Probable Risks

If the monitor is displayed with maximum brightness, you will have to strain your eyes more to view the objects on the screen clearly thus leading to eye fatigue.

Feasible Solutions

  1. It is ideal to place lights parallel to your line of sight in different rows.
  2. Try to use light diffusers so that you can do the desk jobs like writing, reading papers etc. while limiting direct brightness on the computer screen.
  3. While using 4-bulb fluorescent light fixtures, it is ideal to remove the middle bulbs to reduce the brightness of the light to levels well suited with computer tasks, if diffusers or alternative light sources are not available.
    Note: A standard florescent light fixture on a nine-foot ceiling with four, 40-watt bulbs will produce approximately 50 foot-candles of light at the desktop level.
  4. You need to have good desk lighting for proper illumination while writing and reading tasks thus limiting brightness around monitors.
  5. Generally, for paper tasks and offices with CRT displays, office lighting should range between 20 to 50 foot-candles. For LCD monitors, higher levels of light are usually needed for the same viewing tasks (up to 73 foot-candles).

Ergonomic Lighting: Light Source Behind The Display Screen

Probable Risks:

The light sources behind the display screen can create contrast problems, making it difficult to view the screen clearly.

Feasible Solutions:

  1. You can try using b linds or drapes on windows to eliminate bright light. The placement of blinds and furniture should be adjusted to allow light into the room, but not directly into your field of view.
    Note: Vertical blinds are ideal for windows facing east/west directions and horizontal blinds are ideal for windows facing north/south directions.
  2. Indirect or shielded lighting can be used wherever possible. Try to avoid intense or uneven lighting in your field of vision. You should also ensure that lamps have glare shields or shades to direct light away from your line of sight.
  3. If the bright lights from open windows in your work area are at right angles with your computer screen, do change the orientation of your workstation.

Ergonomic Phones

Ergonomic Phone is best option, if you have to spend a lot of time on the phone while using the computer. In today’s competitive market, most of the jobs revolve around telephones and computers as key workstation components. Telephones are an inevitable part of the workstation because they add to the convenience of your work. Yet, this combination is very dangerous as you tend to use both the devices simultaneously which may lead to Ergonomic problems. The cords of the telephone can get tangled up hence causing the user to assume awkward postures.

Ergonomic Phone – Quick Tips :

  • If your job involves speaking over the phone for a long time, do use a speakerphone.
  • Ensure that the speakerphone is close to you so that you don’t have to reach it every time, which in turn causes strain.

Probable Risks in Placement and Use

If the telephone is placed too far away from the user, it causes strain on the shoulder, arm, and neck due to repeated reaching.

Feasible Solutions

  • Let your Ergonomic Phone be placed in the primary or secondary work zone, depending on usage patterns. Thus you can avoid reaching it repeatedly, reducing the possibility of injury.
  • Ensure that the cord of your Ergonomic Phone is out of the work area so that it does not create a tripping hazard.

Ergonomic Phones : Probable Risk

Some users do not want to waste their time when they have to use the phone while working on the computer. Hence they keep the phone pinched between their head and shoulder thus talking over the phone and working on the computer simultaneously. This may cause stress on the neck and especially the ears as they are pressed between the head and shoulders during the entire conversation.

Ergonomic Phone : Feasible Solution

If you have to spend a lot of time on the Ergonomic Phone while using the computer, it is ideal to use a “hands-free” headset. If your co-workers do not have a problem, speakerphone is yet another appropriate solution provided the volume is adjusted for your audibility only.

Ergonomic Phone Recipe

  1. Always use a Ergonomics Telephone with a “hands free” headset if your job at the workstation involves more of manual tasks such as typing so that you don’t strain your neck and head while doing both the tasks simultaneously.
  2. Use a Ergonomic Phone that has a “hands-free” feature.
  3. Ensure that your “hands-free” headsets have volume control options .
