Closed-loop Sensorimotor Integrated (CSMI) Control in Exoneuromusculoskeleton (ENMS) for Precise Wrist-hand Rehabilitation After Stroke
Sponsor: The Hong Kong Polytechnic University
Summary
The goal of this randomized controlled trial is to determine whether using both brain and muscle signals to control a wrist-hand rehabilitation robot can improve recovery in people with chronic stroke. A total of 48 participants will be randomly assigned to one of two groups. Both groups will receive 20 sessions of wrist-hand rehabilitation using an exoneuromusculoskeleton rehabilitation robot. In the closed-loop sensorimotor integrated group, the system will use information from both brain-muscle coordination and muscle activity to recognize the participant's movement intention and provide electrical stimulation and robotic assistance. In the electromyography-driven group, the system will use muscle activity alone to control the electrical stimulation and robotic assistance. The main questions this study aims to answer are: Does control using both brain and muscle signals improve wrist and hand motor function more than control using muscle signals alone? Does this approach produce greater changes in coordination between the brain and muscles? Participants will complete motor-function and brain-muscle assessments before training, immediately after the 20 training sessions, and 3 months after training.

Conditions
Interventions
CSMI-Controlled ENMS
The exoneuromusculoskeleton (ENMS) provides neuromuscular electrical stimulation and robotic assistance for wrist-hand rehabilitation. In the CSMI-controlled intervention, corticomuscular coherence and electromyographic signals are jointly used to identify voluntary movement intention and trigger assistance. Participants will receive 20 training sessions.
EMG-Driven ENMS
The exoneuromusculoskeleton (ENMS) provides neuromuscular electrical stimulation and robotic assistance for wrist-hand rehabilitation. In the EMG-driven intervention, electromyographic activity alone is used to identify voluntary movement intention and trigger assistance. Participants will receive 20 training sessions.
