Abstract
In a previous paper the authors proposed a model of the movement control system of skeletal muscles.
This study aims atverifying this model experimentally.
The following experiments with respect to pronation-supination movement of the elbow joint are carried out.
1) Transient response to small disturbance by prodding
2) The effects of temperature on tremor
3) Transient responses to torque disturbance by a DC motor From the experimental data and the results of analog simulation using the proposed model, the following conclusions are obtained.
1) The 2 modes of oscillation observed in the transient response to small disturbance are due to the mechanical resonance of the forearm and the stretch reflex loop.
2) The stretch reflex loop constructs the minor loop of the movement control system and contributes to the stability of the system.
3) The effects of temperature on tremor result in the change of the dead time and the loop gain of the streth reflex loop.
4) The proposed model is valid in the case of large movement.
