The goal of this project was to develop a device that provides interactive, goal-directed finger therapy to individuals with hemiparetic stroke. The specific design requirements of the device were that it be safe, easy to use, adaptable to varying abilities, and able to record accurate force measurements. The device developed meets all of the design requirements, allowing hemiparetic stroke patients to perform repetitive, therapeutic exercises. We hypothesize that this type of therapy will lead to higher functional gains in stroke survivors, by re-establishing coordinated control over the finger muscles in the affected hand. The device can be used by therapists to track functional gains in hand function, and can be used at the clinic or at home.
