Medical and Chiropractic professionals are increasing advocating the use of Powerball gyroscopes and an excellent device to help with muscle and ligament damage. With practice, speeds in access of 15,000 rpm's can be generated. Rehabilitation - The non-impact nature of NSD Powerball makes it ideal for gentle rehabilitation of sprains, and also in the treatment and prevention of Arthritis, RSI, Carpal Tunnel and Tendoniti Due to the dynamic nature of the device, the force achieved from the device is useful for increasing finger, hand, wrist and arm strength as well as increasing blood flow and ligament strength. As you build up the speed of the rotation will increase. The Powerball (or hand held gyroscope) is a truly dynamic object, there are no batteries and no electricity used, unless you have a model with a rpm counter. When the gyro is spinning, a tipping action will cause it to precess and move in a circular fashion. The gyroscope will respond with a rolling action and the speed of the device the forces generated against your arm build as well. With its gentle yet dynamic, non-impact nature and compact size it can be used anywhere
