Carpal Tunnel Syndrome - Prevention

Prevention

Because many factors can contribute to carpal tunnel syndrome, there is no single way to prevent it. Treating any underlying medical condition is important. Simple common sense may help minimize some of the risk factors that predispose a person to work-related CTS or other cumulative trauma disorders. A patient can learn how to adjust the work area, handle tools, or perform tasks in ways that put less stress on the hands and wrists. Proper posture and exercise programs to strengthen the fingers, hands, wrists, forearms, shoulders, and neck may help prevent CTS.

Corporate Efforts

Many companies are now taking action to help prevent repetitive stress injuries. In a major survey, 84% reported that they were modifying equipment, tasks, and processes. Nearly 85% were analyzing their workstations and jobs, and 79% were buying new equipment. It should be stressed, however, that there has been no evidence that any of these methods can provide complete protection against CTS. The optimal corporate approach, if possible, is to reallocate workers with repetitive stress injuries to other jobs.

Preventing CTS in Keyboard Workers

Altering the way a person performs repetitive activities and replacing old tools with ergonomically designed new ones may help prevent inflammation in the hand and wrist. Most of the interventions described below have been found to reduce repetitive motion problems in the muscles and tendons of the hand and arm. They may reduce the incidence of carpal tunnel syndrome, although there is no definite proof of this effect.

Rest Periods and Avoiding Repetition. Anyone who does repetitive tasks should begin with a short warm-up period, take frequent breaks, and avoid overexertion of the hand and finger muscles whenever possible. Employers should be urged to vary their employees' tasks and work.

Taking multiple "microbreaks" (about 3 minutes each) reduces strain and discomfort without decreasing productivity. Such breaks may include the following:

• Shaking or stretching the limbs
• Leaning back in the chair
• Squeezing the shoulder blades together
• Taking deep breaths
