Outline of Final Research Achievements

Stumbling is the main factor of falling. This research project explored the postural adjustment function of maintaining standing balance while stepping over an obstacle by performing experimental tests in real and virtual environments. The results indicated that the step-over motion evoked a different postural adjustment strategy from simple leg swinging motion or stepping motion, and that the muscle activities of the supporting leg decreased in a virtual condition as compared to real one. These findings are expected to contribute to the field of rehabilitation, for example, developing motor and balance functional trainings.
