Tremor Suppression of Elbow Joint via Functional Electrical Stimulation: A Simulation Study

In this paper, we propose a 1-DOF musculoskeletal model of the elbow joint that consists of a pair of antagonist muscles and one skeleton. Simulation based on the proposed model is performed to study the feasibility of tremor suppression via functional electrical stimulation (FES). In order to effectively attenuate pathological tremor of the movement disorder patients with minimal effect in the voluntary movement, we propose a fuzzy logical controller (FLC), a proportional-derivative (PD) controller and a compensator to regulate the stimulator. Current simulation results have shown satisfactory performance for the postural tremor suppression
