| Outline of Final Research Achievements |
To elucidate some of the common mechanism for postural control of human locomotion, human brachiation under the horizontal ladder was analyzed by kinamatical and electromyographical measurements of the trunk and hind limbs. As a result of this study, it is thought that erector spinae muscles during brachiation act to stabilize trunk posture and swing limbs. Additionally, human brachiation included phasic hinld limbs motions. Vertical motion pattern of the estimated center of body mass was divided into two patterns owing to stride length. It is suggested that trunk and hind limbs phasically act to adjust posture during human brachiation though this type of locomotion is not a daily activity for humans.

| Academic Significance and Societal Importance of the Research Achievements |
ブラキエーションは、ヒトと近縁な類人猿が行うロコモーションである。ヒトのブラキエーションに関する定量的データは、類人猿の運動データと比較するための基礎情報として有用であり、霊長類ロコモーションの進化・適応という人類学の大きな問題に一助しうる。また、懸垂型のロコモーション時に下肢・体幹の働きが確認されたことから、脊髄損傷や下肢切断の患者による上肢優位のロコモーションの円滑な遂行や下肢の賦活化をはかるうえで、応用的な示唆を与えると期待される。
