| Outline of Final Research Achievements |
We studied the dynamics of motor units (MUs) during exercise of upper limbs. The results were as follows. (1) In the case of elbow flexion exercise, a system was constructed to decompose surface motor unit action potentials (SMUAPs). In addition, it was shown that decomposition was possible even when superimposed SMUAP waveforms appeared. (2) A system for estimating the SMUAP territory during elbow flexion exercise was demonstrated and it was shown that it was possible to estimate the size of the MUs．(3) We applied the system to decompose SMUAPs and to estimate the size of MUs during the elbow flexion exercise, and analyzed the MU dynamics.
