Outline of Final Research Achievements

The skeletal muscle contracts based on the electrical signal through motor nerve. Though the muscle cells are fibrillary sets, the two or three dimensional aspect of muscle contraction is known insufficiently, because there are spindle-shaped muscle or pennate muscle.
In this study, the muscular functional aspect was measured using 5×5 displacement MMG (mechanomyogram) array transducer, which has been already developed and could measure two dimensionally. Furthermore, the structural aspect of muscle was measured using the ultrasonic echo equipment. And we have considered the muscle contraction two-dimensionally based on the functional and structural viewpoints and discussed whether theses transducers and method were possibly applied to the fields of sport science and clinical medicine.
