The experiments in this proposal will assess the functional utility and subjective patient experience using a personal exercise cueing system designed to reduce learned non-use of the hemiparetic arm in the days, and weeks immediately following stroke. Up to 36 stroke survivors will be asked to participate in 12 practice sessions each lasting approximately 90 minutes. Participants will be asked to perform simple exercises after receiving a vibration cue. In the first four sessions participants will tap the more-involved wrist; in the second four sessions they will passively move the more-involved elbow through a range of motion; in the final four sessions they will actively move the more-involved elbow through a range of motion.
Accelerometers in the wearable devices will monitor motion of the wrist during the exercise sessions. To verify functional utility of the system, the investigators will examine for differences in the duration of arm movement activity in the cued exercise sessions relative to uncued periods. After all the sessions are complete, subjective user experience will be assessed by asking participants to complete a series of surveys wherein they can provide information about their subjective experiences with the wearable device technology. To assess feasibility of long-term follow-up, the investigators will interview the participants two months later regarding how well they use the more-involved arm to perform daily activities. At this time, they will also be asked to wear the devices for two days to assess the ability to measure arm movement activity at follow-up.
