Don’t CRI – Part 2


Aged no more than 2 decades the health problems generated by the computer industry is comparable to the same created by the industrial revolution in the late 18th century in its social magnitude, severity, diversity and financial implications to the members of this grand profession. In spite of the huge profits generated by the industry, the lords of the same turning a blind eye towards the indicators of this problem, fast attaining epidemic proportions, has not helped much in properly understanding or preventing CRI.

Data collected from the more than 2000 computer professionals afflicted with CRI, who had sought help from Sanjeevani in Bangalore and Trivandrum, on analysis proves that maximum number of people have developed some or other kind of diseases related to the vertebral column (often presented to the doctor as neck pain or stiffness, vertigo or dizziness, low back pain and pain or numbness radiating into the legs) followed by head ache, sinusitis, too frequently recurring cold and running nose and digestive problems including excessive gas formation – flatulence- and pain in the eye or problems of vision as the third. More than 75% of them have complained of very high mental stress, sleeplessness and excessive fatigue. In comparison with the normal population, computer professionals are highly prone to High blood pressure and diabetes, as a group, especially comprising of maximum number of youth. Fertility and marital bliss are also evading this supposed to be rich population at an alarming rate.

Studies suggest that 20 percent to 25 percent of computer users worldwide, both vocational and recreational, have symptoms related to their computer activities. The first CRI “epidemic” was noticed in Australia 15 years ago and then emerged in many other industrialized countries.

There is a great need for spreading the awareness about CRI because it is devastating not only for the injured party but it also affects the company he works for. It accounted for 66% of work related illnesses in the US, in 1999. The estimated costs in lost productivity and compensation due to it are in the region of $60-100 billion annually. No one is immune to CRI, and it can seriously disrupt work and domestic life. About 20-25 % of all computer users worldwide are estimated to have it, which is why it is essential to raise public awareness as quickly as possible before a new generation of computer users is exposed to the risks.

Due to lack of awareness about CRI, Computer users tend to ignore its initial symptoms. A survey of 500 software professionals at Hyderabad (in 2000) established that 50% had symptoms of established CRI. Preliminary results of an ongoing survey among over 400 IT professionals in projects it as high as 75%.

The pattern and nature of CRI in India is significantly different from that in the west. There may be significant anthropological differences in body shape and dimensions work practices and furniture design that only a comprehensive study can unearth. As these problems are unique to our country, so should the solutions.

In India, thanks to the lack of adequate laws and procedures, employers don’t have any obligation to compensate for the problems accrued by the employees in long run. Government laws and regulations on employee welfare and safety do not show any concern for the provision of ergonomically designed office products, tools and work environment.

As more and more work, education and recreation involves computers, everyone needs to be aware of the hazard of Repetitive Strain Injuries (Cumulative Trauma Disorder). i.e. to the hands and arms resulting from the use of computer keyboards and mice. This can be a serious and very painful condition that is far easier to prevent than to cure once contracted, and can occur even in young physically fit individuals. It is not uncommon for people to have to leave computer-dependent careers as a result, or even to be permanently disabled and unable to perform tasks such as driving or dressing themselves.

What are the Symptoms?

● Tightness, discomfort, stiffness, soreness or burning in the hands, wrists, fingers, forearms, or elbows

● Tingling, coldness, or numbness in the hands

● Clumsiness or loss of strength and coordination in the hands

● Pain that wakes you up at night

● Feeling a need to massage your hands, wrists, and arms

● Pain in the upper back, shoulders, or neck associated with using the computer.


Any computer keyboard user, including pre-school children, who uses the computer 2 or more hours a day, is at high risk for CRI. They are in the 20-40 year age group, which is the most productive one. It is estimated that a large proportion of the software professionals, students and other computer users (e.g. secretaries, clerks, cashiers, etc) in India would soon develop CRI, if the current situation prevails.

As with other things in life, too much of anything is dangerous. But that doesn’t mean that one should avoid using computers or alter the duration of computing sessions. A judicious mix of working habits, proper ergonomic infrastructure support and medical support & care can prevent the development of most of the symptoms.

As you know, prevention is better than cure. Some prevention tips have been given which is sure to make you feel computing a safe & healthy experience.


Common causes of musculoskeletal problems include poor workstation design, bad posture and sitting down for extended periods of time. The vertebrae of the spine are arranged in a loose ‘S’, with a slight curve in the lower back. The typical office chair offers little support and actually encourages poor posture by forcing you to round out your lower back and hunch your shoulders. Symptoms of musculoskeletal problems include:

● Sore muscles, particularly the shoulders and upper back
● Stiffness
● Headache
● Backache.

Prevention tips:

Suggestions to reduce the risk of musculoskeletal problems include:

● Correct posture at the desk: A monitor position lower and farther away may be better. The chair and keyboard are to be set so that the thighs and forearms are level (or sloping slightly down away from the body), and that the wrists are straight and level – not bent far down or way back.

● Position your keyboard at a height that allows your elbows to rest comfortably at your side, roughly parallel with the floor and level with your keyboard. While you are actually typing your wrists should not rest on anything, and should not be bent up, down, or to the side. Your arms should move your hands around instead of resting your wrists and stretching to hit keys with the fingers. (palm rests give you a place to rest your hands only when pausing from typing, not while you are typing.) When you stop typing for a while, rest your hands in your lap and/or on their sides instead of leaving them on the keyboard.

● Wrists also should not be bent to the side, . . .

. . . but instead your fingers should be in a straight line with your forearm as viewed from above.

(All of the above is easier to do if you tilt the back edge of your keyboard down, away from you. Put a prop an inch or two thick under the edge of the keyboard closest to you, but make sure the whole thing is still low enough so you aren’t reaching up.)

● Take frequent short breaks and go for a walk or perform stretching exercises at your desk. Stand often. Take lots of breaks to stretch and relax. This means both momentary breaks every few minutes and longer breaks every hour or so.

● Adjust your chair so that your feet rest flat on the floor & Switch to an ergonomic chair, which helps your spine to naturally hold its ‘S’ curve while sitting.

● Use a footstool (if your feet do not rest on the floor when the chair is adjusted to have the arms in a good posture).

Ayurvedic prevention tips:

Massaging daily with oils such as Dhanwantaram OR Shashtikadi lepa tailam in a specific manner so as to loosen and strengthen the constantly injured muscles can be one of the best prevention for many who is prone to CRI. As CRI is a repetitive strain Injury, repetitive and regular support through medicines is found to be very effective in the prevention and management of this problem. The self-massaging skills can be developed with proper guidance from a doctor. Also getting massaged through the Sulochana techniques is equally effective in warding of CRI.

Ayurvedic cure:

Includes specialized external manipulation of muscles and bones and judicious internal medication. Medicines such as Narayana Tailam, and treatment procedures like Sulochana, Rookshaswedam, Pizhichil etc administered under proper supervision of expert doctors and internal medicines like kashayam and grithams administered timely proves very fruitful in helping people to come out of the problems of CRI.


Muscles and tendons can become irritated and inflamed by repetitive movements and awkward postures. This is known as ‘overuse injury’. Carpal tunnel syndrome is a common example of an overuse injury associated with computer work. This painful disorder of the hand is caused by pressure on the main nerve that runs through the wrist. The fingers are also prone to overuse injury, particularly the finger that clicks the mouse buttons. Symptoms of an overuse injury include:

● Pain
● Swelling
● Restricted mobility of the joint
● Weakness
● Numbness.

Prevention tips:

Suggestions to reduce the risk of overuse injuries include:

● Keep your mouse at the same height as your correctly positioned keyboard.

● Position the mouse as close as possible to the side of the keyboard.

● Use your whole arm, not just your wrist, when using the mouse.

● Hold the mouse lightly, don’t grip it hard or squeeze it. Place the pointing device where you don’t have to reach up or over very far to use it; close to the keyboard is best. Better yet: learn and use keyboard equivalent commands, whenever possible, as no pointing device is risk-free. Even trackballs have injured users.

● Type lightly & gently & don’t pound on the keys, use a light touch.

● Keep your arms & hands warm. Cold muscles & tendons are at much greater risk for overuse injuries, and many offices are over-air-conditioned.

● Eliminate unnecessary computer usage. No amount of ergonomic changes, fancy keyboards, or exercises is going to help if you are simply typing more than your body can handle. Don’t try to be the fastest, most powerful hacker around – the cost is too high. Also: is there recreational computer use you can reduce? Can some of your electronic mail messages be replaced by telephone calls or conversations in person? And lose the computer/video games . . ., which often involve long, unbroken sessions of very tense keyboard or controller use. If nothing else, PAUSE the game every 3 – 4 minutes. Don’t sacrifice your hands to a game!

● Mix your tasks to avoid long, uninterrupted stretches of typing. Use two hands to perform double key operations like ctrl-c or Alt-c instead of twisting one hand to do it.

● Remove the hands from the keyboard when not actively typing, to allow the arms to relax.
