A hand rehabilitation device including a circular planar disk having a series of spread-apart recesses in its circumference receives the fingers of a patient's hand with the thumb inserted through a selected one of a plurality of apertures. The joint of the finger extending across the disk may be active or passively exercised while the patient holds the disk.
Claims2
A hand rehabilitation device, comprising:
- a planar circular disk formed from material returning to a position of repose after being manually flexed,
