Enabling Stroke Rehabilitation in Home and Community Settings: A Wearable Sensor-Based Approach for Upper-Limb Motor...

Area of Science:

• Rehabilitation Engineering
• Neurorehabilitation
• Human-Computer Interaction

Background:

• High-dosage motor practice is crucial for functional recovery post-stroke.
• Home-based rehabilitation and increased upper limb use during Activities of Daily Living (ADL) are key strategies.
• Current methods lack precise tracking and feedback for in-home practice.

Purpose of the Study:

• To develop and validate a novel technological approach for monitoring upper limb movements in stroke survivors.
• To enable detection of goal-directed movements during ADL for timely feedback.
• To assess motor performance quality during in-home rehabilitation exercises for targeted feedback generation.

Main Methods:

• Development of a system to detect goal-directed upper limb movements during ADL.
• Implementation of algorithms to assess motor performance quality in rehabilitation exercises.
• Validation of detection accuracy using statistical measures.
• Preliminary survey of occupational therapists and stroke survivors on clinical adequacy.

Main Results:

• The system successfully detected goal-directed movements during ADL with an 87.0% statistic.
• Poorly performed movements in rehabilitation exercises were identified with an 84.3% score.
• High acceptance rates were reported: 91.7% of therapists and 88.2% of stroke survivors expressed willingness to use the technology.

Conclusions:

• The proposed technology effectively detects upper limb movements during ADL and assesses rehabilitation exercise quality.
• This approach facilitates timely and appropriate feedback, promoting increased limb use and higher quality rehabilitation.
• The technology shows strong potential for clinical adoption and integration into stroke recovery programs.
