As an active programmer and bass player, I used to suffer cramps and wrist pain after extended hours. After a friend suggested it I bought a metal NSD powerball to train the micro-muscles in my hands. I spend about 20 minutes a day training it and after about 3 months the pain stopped and went away - I still regularly use it in 3 minute on, one minute rest intervals. I also use regular keyboards. |
