Fig. 3From: Closed-loop neuromuscular electrical stimulation using feedforward-feedback control and textile electrodes to regulate grasp force in quadriplegiaTextile-based electrodes in sleeve form. (a) Natural hand position when stimulation is off (b) Stimulation turned on, evoking index finger flexion and pinch-type movement (subject NMES05). (c) and (d) Stimulation evoked a cylindrical grasp with sufficient force to hold a full (750 mL) water bottle against gravity in two study participants with quadriplegia (NMES04 and NMES05 respectively)Back to article page
