Outline of Final Research Achievements

In order to improve body function of the elderly, it is necessary to understand how humans could achieve adaptive motion even from different chair heights or motion speeds. This research employs the idea of muscle synergy to identify muscle coordination structure from eight muscles measured from lower legs during measurement experiment.
As a result, three muscle synergies were extracted from human standing-up motion regardless of environmental change. Moreover, it was shown that spatial patterns of muscle synergies were similar among different environments. On the other hand, it was clarified that humans could change amplitude and duration of muscle synergies' temporal patterns to generate adaptive standing-up motion.
