Repetitive Stress Injuries 

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 doc

-

tor 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.
