Abstract:
In this paper, how to estimate the stimulus patterns of the functional electrical stimulation, FES is reported. The authors try to use a musculoskeltal model in order to estimate the patterns of muscle strength depending upon the motions. They make a wrist joint model and presume the position of the rotary axis of the wrist joints. And they measure the motions of the muscles around the wrist joints. Using the measurement method of wrist joint movement, they estimate the muscle strength in FES. They produce a device to measure the movements of wrist joints and make a experiment on three males. They give stimuli to their upper limbs and measure the moments and the positions of the rotary three axes of their wrist joints. They raise an example that they put stimuli on their muscle of flexor carpi radialis. Then, they presume the relationship between the strength of stimulation and the muscle strength. They conclude that they can construct a model to simulate the muscle movements by making clear the relationship.
