Repetitive strain injury occurs when the movable parts of the limbs are injured. Most of the times, the victims of this injury are computer professionals, musicians, students, and others who have to use their hands regularly in a repetitive manner.
The users experience constant pain in the hands, elbows, shoulders, neck, and the back. Other symptoms are cramps, tingling, and numbness in the hands. The hand movements of the user may become clumsy and the person may find it difficult even to fasten buttons.
Another variant may produce painful symptoms in the upper limbs, but the site may be difficult to locate.
The common diagnoses seen in this group are Carpal Tunnel Syndrome, Tenosynovitis, Bursitis, White Limb, and Shoulder pain. A major cause is strain due to long unbroken periods of work. Ergonomics or the lack of it plays a very important role. Lack of information about the condition leads to neglect by the concerned individuals.
People concerned should seek medical attention when early symptoms set in. Measures that can be adopted at an individual level include:
Posture: The recommended posture to sit in front of a computer is semi-reclined with the forearms resting in a cradle or on an extension of the keyboard support. There should be ample support for the back. The hands should be free and point in the direction of the forearms. The feet should rest on the ground or feet support. The distance of the monitor should be 18 inches or more and at a slightly lower level than the eye level.
Rest: The user should take short breaks every 15 minutes and slightly long breaks after every hour.
Hydration: Drink adequate fluids to keep the tendons and soft tissues soft.
Shortcuts: Use keyboard shortcuts instead of mouse. Touch the keyboard softly and do not pound at it. The wrist should rest on the table or wrist rest.
Telephone use: Don’t cradle the telephone between the face and shoulder while working, as this can lead to neck strain.
Messages: Don’t use the computer while conveying messages in person or through the intercom.
No games: Games or surfing at work may increase stress on your hands.
Preventive Measures at the Organizational Level: Organizations that use computers in a big way can also adopt certain preventive measures.
1.You need to educate your employees on the importance of adopting a proper posture.
2.Ensure that all your employees are using quality ergonomic furniture that will save loss of working hours by guaranteeing full comfort of the employees.
3.Give periodic reminders through lectures and audio-visual presentations by medical professionals on the importance of taking good care of health while using computers.
When symptoms set in, consult an orthopedic surgeon. Do not make the diagnosis yourself. The diagnosis will be made from the history and clinical findings as there will be no changes in X-rays, since the soft tissues are involved. Nerve conduction studies can confirm the diagnosis. In cases detected earlier, attention to ergonomics will restore normalcy.
In cases diagnosed late, orthopedic treatment like injections and even minor surgery may be necessary.
Remember that all the computer related hazards are not going to hamper your life in a very short span of time. But it may take years to show the symptoms. As I said earlier, prevention is better than cure.
