Fig. 5From: Closed-loop neuromuscular electrical stimulation using feedforward-feedback control and textile electrodes to regulate grasp force in quadriplegiaClosed-loop response to increasing and decreasing target (desired) forces. a The target force is increased from 2.5 to 5 N causing a rapid response that overshoots the final desired value, but settles within +/− 10% of the final value in less than 1 s. b The target force is decreased from 5 to 2.5 N associated with a rapid response, settling within 1 sBack to article page
