At Home Wearable Sensors and Smartphone for Stroke Survivors With Upper Limb Motor Challenges.

The experimental design is composed of three phases: baseline, intervention, and retention. During the first two weeks (baseline), subjects will wear sensors, but no additional features (e.g., feedback, goal-setting, and weekly Zoom calls with clinicians) will be provided. For the next four weeks (intervention), subjects will wear sensors and have access to all intervention features, including weekly Zoom calls and goal-setting with clinicians. They will be encouraged to use the more impaired arm as much as possible. In the final two weeks (retention), the mobile intervention and clinician interactions will be removed, while subjects continue to wear sensors to examine the effects of withdrawing feedback.
