A musculoskeletal model that allows to simulate the tremor of wrist joint with three degrees of freedom (DoFs) is developed. The model includes five muscles, extensor carpi radialis brevis, extensor carpi radialis longus, extensor carpi ulnaris, flexor carpi radialis and flexor carpi ulnaris. Simulation of tremor generation based on the 3-DoF model is performed. The tremor disorder can be generated in two directions: flexion-extension and radia-ulnar deviation. Accordingly, experiment is conducted on healthy subjects to verify the feasibility of artificial tremor generation via functional electrical stimulation (FES). Simulation results have shown qualitative agreement with the experimental results.
