Home-based Rehabilitation Monitoring System With Wearable Devices and Self-Report Application

Research on Evaluation of Home-based Rehabilitation Monitoring System With Wearable Devices and Self-Report Application

The goal of this clinical trial is to evaluate whether monitoring and providing feedback on the performance of a home-based exercise program using an integrated wearable monitoring system improves physical and cognitive function, and activity level in participants with stroke.

The integrated wearable monitoring system consists of an insole-type gait analyzer for objective gait assessment, a wrist-worn activity tracker for monitoring daily physical activity, and a self-report mobile application for delivering feedback and collecting participant-reported information.

This study also aims to assess participant satisfaction with the integrated wearable monitoring system during a 6-week home-based gait rehabilitation program.

The main questions this study aims to answer are:

1. What effect does monitoring and providing feedback using an integrated wearable monitoring system have on physical and cognitive function, and activity level during a home-based gait rehabilitation program?
2. How satisfied are participants with the use of the integrated wearable monitoring system?

Researchers will compare an intervention group that receives the integrated wearable monitoring system with a control group that performs the same home-based exercise program without wearable monitoring and feedback.

Participants in the intervention group will receive an insole-type gait analyzer, a wrist-worn activity tracker, and access to a mobile application, along with training in a prescribed home-based exercise program. During the 6-week intervention period, participants will wear the insole-type gait analyzer and the activity tracker while performing the home-based exercise program and will use the mobile application to receive feedback and self-report selected daily health-related information. After completion of the 6-week program, the investigators will conduct a satisfaction survey to evaluate participant experience with the integrated wearable monitoring system.

After obtaining written informed consent, a screening assessment is conducted to determine participant eligibility.

The screening assessment evaluates whether participants, regardless of assistive device use, are able to walk independently for more than 10 meters, based on an assessment of baseline symptoms and clinical signs. Eligible participants who pass the screening assessment are randomly assigned to either an intervention group or a control group.

Both groups undergo an initial assessment, during which baseline gait-related outcomes are measured. Participants are provided with information regarding their current gait status and general characteristics of normal gait and are instructed in a standardized home-based exercise program.

Participants assigned to the intervention group are provided with an integrated wearable monitoring system consisting of an insole-type gait analyzer, a wrist-worn activity tracker, and access to a mobile application. The researcher provides training on the proper use of the wearable devices and application and instructs participants to wear the devices as frequently and for as long as possible during daily activities and exercise sessions to enable continuous recording of gait patterns and physical activity. Based on the collected wearable data, the researcher provides individualized feedback to participants in the intervention group via telephone on a weekly basis.

Participants in the control group perform the same home-based exercise program but do not receive wearable monitoring devices or feedback related to their exercise performance.

At the completion of the 6-week home-based exercise program, an exit assessment identical to the initial assessment is conducted for both groups. In addition, participants in the intervention group complete a satisfaction survey to evaluate their experience with the integrated wearable monitoring system.

Throughout the intervention period, device-related issues, including malfunctions and usage interruptions, are documented. Usage patterns and satisfaction levels associated with the wearable monitoring system in the intervention group are analyzed, and pre- and post-intervention outcome measures are compared between the intervention and control groups.
