GRASP is a self-directed arm and hand exercise program for which is supervised by a therapist, but done independently by the participant (and with their family if possible). GRASP has been shown to improve arm and hand function and strength after stroke. There are two versions of the program: Hospital GRASP and Home GRASP. Both versions prescribe one hour of daily GRASP exercise, plus encourage the patient to use the stroke-affected arm and hand as much as possible.
