Outline of Final Research Achievements

To understand the mechanism of unstable postural and motor control with age, this study investigated the motor performance and muscle activities of legs in healthy young adults and elder adults using the visually guided tracking task in the force platform. The postural control of the elderly group influenced by feedback during standing, and responses of both the initiation and the termination of movement were delayed and variable. This study suggests that the role of biarticular muscles of legs and the vertical postural strategy (i.e., antigravity control) is important to control the stability during standing in elders.
