Review of proactive measures to reduce costs and future injury rates
According to the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA), repetitive strain injuries are the nation’s most common and costly occupational health problem, affecting hundreds of thousands of American workers and costing more than $20 billion a year in workers’ compensation. According to the U.S. Bureau of Labor Statistics, nearly two-thirds of all occupational illnesses reported were caused by exposure to repeated trauma to workers’ upper bodies (wrist, elbow, or shoulder). One common example of such an injury is carpal tunnel syndrome.
Carpal tunnel syndrome is the most common nerve compression disorder of the upper extremity. This condition affects one percent of the general population and five percent of the working population who must undergo repetitive use of their hands and wrists in daily activities. Furthermore, surgical treatment for carpal tunnel syndrome is the most frequent surgery of the hand and wrist, with 463,637 carpal tunnel releases performed annually in the U.S., accounting for $1 billion in direct costs. Carpal tunnel syndrome results in the highest number of days lost among all work-related injuries. Almost half of the carpal tunnel cases result in 31 days or more of work loss, and only 23% of all carpal tunnel syndrome (CTS) patients return to their previous professions following surgery, according to the Bureau of Labor Statistics and the National Institute for Occupational Safety and Health.
Examples of repetitive strain injuries (RSI) include bursitis, carpal tunnel syndrome (CTS), epicondylitis, ganglion, rotator cuff syndrome, tendinitis, tenosynovitis, trigger finger, nerve entrapment disorders, and ulnar tunnel syndrome.
The three primary risk factors for RSI are:
- Poor posture
- Poor technique
- Overuse
The most common RSI signs and symptoms include:
- Tenderness in the affected muscle or joint
- Pain in the affected muscle or joint
- A throbbing (pulsating) sensation in the affected area
- Pins and needles (tingling) in the affected area, especially the hand or arm
- Loss of sensation in the hand
- Loss of strength in the hand
- Weakness, lack of endurance
Ten easy ways to reduce your risk of developing RSI:
- Take breaks when using your computer. Every hour or so, get up and walk around, get a drink of water, stretch any tight muscles, and look at a distant object to rest your eyes.
- Use good posture. If you can’t maintain good posture, it’s probably time to take a break from typing. If you constantly struggle to maintain posture, you may need to adjust your workstation or chair, or strengthen the muscles that support good posture.
- Use an ergonomically optimized workstation to reduce strain on your body.
- Exercise regularly. Include strengthening, stretching, and aerobic exercises. Yoga and Pilates can be especially helpful.
- Limit computer use when possible. Don’t email when you can walk down the hall or pick up the phone. It’s not only better for your hands but also more personal. Think before you type to avoid unnecessary editing.
- Don’t stretch for hard-to-reach keys (e.g., BACKSPACE, ENTER, SHIFT, CONTROL). Instead, move your entire hand so you can press the desired key comfortably. This is crucial when programming or typing in LaTeX, where non-letter keys are used extensively.
- Let your hands float above the keyboard when typing. Move your entire arm when using the mouse or typing hard-to-reach keys, keeping the wrist joint straight at all times. This allows the larger muscles in your arm, shoulder, and back to do most of the work, instead of relying on the smaller, more vulnerable muscles in your hands and wrists. If you find this difficult, your shoulder and back muscles may need strengthening. It’s okay—and even beneficial—to rest your elbows or wrists when not typing.
- Use both hands for combination key strokes, such as those involving SHIFT and CONTROL.
- Avoid gripping writing utensils tightly. Someone should be able to easily pull the pen or pencil from your hand while you’re writing. If you have to press too hard, get a new pen with grip element.
- Focus treatment on the cause, not just the symptoms. Your doctor or therapist should focus on correcting posture and improving anatomical function so your body can heal itself. Treatment typically includes physical therapy combined with a home exercise program designed to stretch tight muscles and strengthen weak ones. However, no amount of therapy can overcome excessive typing, poor posture, a bad workstation, or poor typing technique.
