| Outline of Final Research Achievements |
The study aimed to develop a evaluation system of muscle quality using a electromyography signal acquiring device that can acquire signal during weight-bearing standing-shaking-board exercise in combination with electrical muscle stimulation. Based on the fact that voluntary movement usually begins with the contraction of slow-twitch muscle fibers whereas contraction induced by an electric stimulus begins with fast-twitch muscle fibers, we developed a novel training method of active CKC exercise on a shaking board while an electric stimulus is applied to the muscles. Since electrical stimulation output can affect EMG signal acquisition, EMG signal were recorded during the schedule of an interval of the electrical stimulation. Biphasic 20Hz pulses were employed in order to induce contractions of the lower extremity muscle at a maximally tolerated current level. Using integration analysis and wavelet frequency analysis, a evaluation system of muscle quality was developed.
