Repetitive Stress Injuries (RSI)
It is believed that overusing the muscles
and tendons of the fingers, hands, arms,
and shoulders may cause soreness,
swelling, numbness, weakness, and
extreme pain in those areas. Certain
repetitive hand activities may put you at a
high risk for developing a Repetitive
Stress Injury (RSI). An extreme RSI
condition is Carpal Tunnel Syndrome
(CTS), which could occur when your wrist
swells and squeezes a vital nerve that
runs through the area. Some believe that
prolonged exposure to vibration may
contribute to CTS. CTS can cause severe
pain for months or even years.
To reduce the risk of RSI/CTS, do the following:
• Avoid using your wrist in a bent, extended, or twisted position. Instead try
to maintain a straight wrist position. Also, when grasping, use your whole
hand, not just the thumb and index finger.
• Take periodic breaks to minimize repetition and rest your hands.
• Reduce the speed and force with which you do the repetitive movement.
• Do exercises to strengthen the hand and arm muscles.
• Immediately stop using all power equipment and consult a doctor if you
feel tingling, numbness, or pain in the fingers, hands, wrists, or arms. The
sooner RSI/CTS is diagnosed, the more likely permanent nerve and
muscle damage can be prevented.
