Hand disability after stroke has a profound negative impact on functional ability and independence. Hand therapy may be augmented with sensory stimulation for better outcomes. We have developed a novel sensory stimulation - unfelt vibration applied via a wristwatch. Participants will receive this novel stimulation with hand task practice therapy or therapy only to determine if use of this stimulation is better for recovery.

Sensory stimulation has been shown to enhance rehabilitation outcomes. However, most sensory stimulation devices interfere with natural hand tasks. Thus, a new wearable stimulation device has been developed to deliver imperceptible vibration to wrist skin. This study is to evaluate the community use of the device for patients with neurologic movement disorders. Participation will include wearing the provided device and charging the device every night. The knowledge regarding community use of the device may contribute to improving the device functionality and usability for future users of the device.

The purpose of this study is to develop and test if upper limb task practice and muscle activity training improve upper limb function in stroke survivors. Participants will be asked to come to the laboratory 3 times a week for 6 weeks to receive upper limb task practice and/or muscle activity training. Participants will also come to the laboratory for additional 3 visits for assessments of upper extremity function. The total duration of the study will be 2.5 months.

Adherence to home exercise is important to achieve upper limb recovery after stroke. However, adherence is typically low. Therefore, a new home exercise program with an Apple Watch and iPhone app was created to improve adherence to upper limb exercises for stroke survivors at home. Participants will come to our lab to experience the new home exercise program. Participants who opt for home use will bring the device home to try the new home exercise program at home. The purpose of this study is for researchers to examine usability and feasibility of participants using the new home exercise program.
