Upper Limb Dysfunction Following Stroke
Conditions
Interventions
Control group:The control group was treated with the clinical conventional fixed-parameter open-loop neuromuscular electrical stimulator (model: German Pierenkemper NT2000). This device does not have
Model Group:The experimental group adopted the closed-loop intelligent electrical stimulation system developed by our research team. This system integrates high-precision surface electromyography sens
