Robot-Assisted Tai Chi for Upper Limb Rehabilitation in Stroke Patients

Condition(s) studied

Investigational drug(s) / intervention(s)

Robot-Assisted Tai Chi Training: This intervention involves robot-assisted Tai Chi training for upper limb rehabilitation, delivered in a seated position to ensure participant safety and comfort. Each 60-minute session consists of a 5-minute warm-up/preparation phase, followed by three 15-minute segmented functional training phases incorporating Tai Chi-inspired movements to target upper limb coordination, range of motion, and strength recovery, interspersed with two 5-minute rest intervals. The protocol is administered 5 times per week over 4 weeks, with robotic assistance tailored to guide functional upper limb trajectories while minimizing compensatory movements.

Conventional rehabilitation training: This intervention follows evidence-based clinical guidelines for post-stroke upper limb rehabilitation, focusing on therapist-guided task-oriented training that integrates activities of daily living (ADL) such as table wiping and clothes hanging. Sessions emphasize progressive functional integration, with exercises adjusted weekly based on patient performance. Training is delivered in 60-minute sessions (1 session/day), 5 days per week over 4 weeks, under direct therapist supervision to ensure proper movement patterns and safety.

Study summary

This study aims to compare the effectiveness of Robot-Assisted Tai Chi Training (RATT) versus conventional rehabilitation in improving upper limb motor function post-stroke, and to explore the neuromuscular mechanisms of RATT. Participants will be randomly assigned to one of two groups:

1. Robot-Assisted Tai Chi Training group: Participants will receive guided Tai Chi arm movements with robotic assistance to enhance coordination and strength.
2. Conventional rehabilitation group: Participants will perform standard exercises (e.g., stretching, repetitive task practice).

Both groups will receive 60-minute sessions, administered 5 days a week, over 4 weeks. Researchers will measure improvements using clinical scales (e.g., Fugl-Meyer Assessment) and monitor safety.

Eligibility

Primary outcome measure(s)

• Fugl-Meyer Upper Extremity Scale — 4 weeks (post-intervention)
  Score range 0-66, higher scores indicate better upper limb motor recovery.
