Addressing Arm Non-use by Encouraging Idle-time Activity During Early Recovery from Stroke

The experiments in this proposal will assess the utility and subjective patient experience performing idle time exercise intervention designed to reduce learned non-use of the hemiparetic arm in the days, and weeks immediately following stroke. Exercise will be cued by wearable technology that provides vibrotactile cues similar to those provided by FitBit devices. Participants will be asked to perform simple exercises after receiving a vibration cue. In the first four sessions they 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. We will interview the participants two months later regarding how well they use the more-involved arm to perform daily activities.
