Résumé
In this paper, the origin of tremor is studied based on a neuromusculoskeletal model in combination of central oscillation and peripheral mechanism. Matsuoka neural oscillator is adopted as the cental oscillation that can generate tremor of wrist joint. It is known that reflex loops (spindle organ, Renshaw cell and Golgi tendon organ) in peripheral system can also cause tremor. The coaction of central oscillation and peripheral mechanism on the tremor is analyzed. Useful simulation results are given.
