A personalized sensor-controlled microstimulator system for arm rehabilitation post-stroke. Part 2: objective outcomes and patients’ perspectives
Objective: To examine the effect of home-based electrical stimulation using closed-loop control of implanted microstimulators on upper limb function and impairment, and subjects’ perception of the system.
Methods: Six chronic post-stroke subjects, with reduced upper limb function, who had taken part in Phase 1 of the study, were fitted with a closed-loop control system and used the system at home during the performance of functional tasks for 12 weeks. Main outcome measures were: Action Research Arm Test (ARAT); Fugl-Meyer Motor (FMA) and motor control (tracking index). Subjects’ perception of the system was assessed in a structured interview.
Results: Improvement in ARAT (P=0.05), FMA (P =0.02) and Tracking Index (P=0.03) during phase 3. Five subjects said using the system had changed their lives and improved their function, all performed functional tasks with the system, but external components were inconvenient.
Conclusions: Closed-loop control improved in function. Subjective assessment identified that the external sensors were effective.
