The Digiball has been designed as an exercise aid for anyone with arthritis, rheumatism or Repetitive Strain Injury(RSI) in the hands. It is also helpful for rehabilitation after a hand injury where there is a need to increase suppleness and/or flexibility. The exercise is simplicity itself. You simply squeeze the Digiball with the fingers, singly or together, and increase the frequency and pressure as improvement allows.
