Medical Scientific Evidence:

The Powerball is a type of gyroscope using centrifugal forces to generate inertia and thus exercise the muscles acting on the wrist joint. A pilot study on the use of Powerball in healthy subjects revealed a significant increase in muscle endurance, but not muscle

grip strength, over a four-week period of training. However, the true benefit of the Powerball lies most likely in the multidirectional motion generated by the gyroscope, which demands a reflex activation of the wrist muscles and an unconscious activation of both agonist and antagonist muscles. Additionally, this instrument is easy for the patient to use at free will and may thus promote an adherence to Reactive muscle activation (RMA) training.

The Powerball is a gyroscope that will exert a multidirectional inertia on the wrist muscles when activated. The purpose of the Powerball is to stimulate an unconscious proprioception re-education through a reactive muscle activation.
