6Repetitive Stress InjuriesIt 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 handactivities may put you at a high risk for developing a Repetitive StressInjury (RSI). An extreme RSI condition is Carpal Tunnel Syndrome(CTS), which could occur when your wrist swells and squeezes a vitalnerve that runs through the area. Some believe that prolonged exposureto vibration may contribute to CTS. CTS can cause severe pain formonths 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 grasp-ing, 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 move-ment.• Do exercises to strengthen the hand and arm muscles.• Immediately stop using all power equipment and consult a doctor ifyou feel tingling, numbness or pain in the fingers, hands, wrists orarms. The sooner RSI/CTS is diagnosed, the more likely permanentnerve and muscle damage can be prevented.EQUIPMENTWARNING DANGERUse only ECHO approved attachments.
