Motivation-Induced Movement Therapy: Enhancing Upper Limb Engagement in Stroke Survivors Through Ring Sensors and Data Visualization.
The goal of this clinical trial is to learn if wearable sensor data visualization on smartphones can improve the use of the stroke-affected limb during everyday activities. Chronic stroke survivors (\>12 months from onset) ages 18-80 years old with residual upper extremity motor impairments may be eligible to participate. The main question it aims to answer is: Does the mobile health (mHealth) intervention help to improve the use of the stroke-affected upper-limb during daily living? The study is designed so each participant serves as their own control. Researchers will compare information from the baseline, intervention, and retention time periods to see if visualizing the data on the smartphone impacts the participant's daily use of the arm. Participants will be asked to wear a set of wearable ring and wrist sensors and interact with a custom-designed smartphone app, aiming to increase the use of their stroke-affected limb during daily activities as much as possible. They will receive feedback from the app, communicate with study therapists, participate in goal setting, complete clinical assessments, and share about their experience using the system during a virtual interview.
