Repetive Stress Injuries

Repetitive Strain Injuries occur from repeated physical movements doing damage to tendons, nerves, muscles, and other soft body tissues. Occupations ranging from meatpackers to musicians have characteristic RSIs that can result from the typical tasks they perform. The rise of computer use and flat, light-touch keyboards that permit high speed typing have resulted in an epidemic of injuries of the hands, arms, and shoulders. Use of pointing devices like mice and trackballs are as much a cause, if not more so.

The thousands of repeated keystrokes and long periods of clutching and dragging with mice slowly accumulates damage to the body : another name for the condition is Cumulative Trauma Disorder. This can happen even more quickly as a result of typing technique and body positions that place unnecessary stress on the tendons and nerves in the hand, wrist, arms, and even the shoulders and neck. Lack of adequate rest and breaks and using excessive force almost guarantee trouble.

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.
