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.
