Upper Limb Motor Function Rehabilitation System Leveraging Pressure-Sensitive Intent Recognition.

ABSTRACT: Functional electrical stimulation (FES) enhances daily living and rehabilitation outcomes for stroke patients but faces challenges in intention recognition, individual adaptability, and closed-loop control. To address these, a reconstruction system is presented for upper limb motor function, employing highly pressure-sensitive liquid metal magnetorheological elastomers (LMMRE） to detect muscle surface pressure. It can dynamically modulate functional electrical stimulation based on muscle force signals, enabling continuous execution of wrist movements for stroke patients. The system markedly improves patient mobility, with wrist lifting angles increased from 14° to 47°, and lifting speed nearly doubled. Clinical trials confirm the system's superior efficacy in promoting motor recovery and r
