Healthy Adults Clinical Trial
Official title:
Effect of Constraining Joint Motions on Postural Control
A major advantage of understanding a neural control scheme is able to simultaneously perform multiple tasks based on the Uncontrolled Manifold (UCM) hypothesis by taking advantage of motor redundancy. The present study aims to investigate this hypothesis further by examining the effect of artificially eliminating knee and lumbar-thoracic joint motions on postural control when the arms performing targeting task simultaneously in standing. Subjects (Younger group: 20~35 years old; Elder group: 60~85 years old) will execute a targeting task with and without an additional ball-balancing task in standing with free joint motions and with restricted joint motions. The investigators expect to recruit 50 subjects for each group. Analyses of joint configuration variance on the stability of the center of mass (COM) position and the hand path will be performed using the UCM method of variance analysis. This method partitions joint configuration variance into one component consistent with the use of motor abundance and a component that leads to COM position or hand path variability. Furthermore, the differences between the younger group and the elder group will be evaluated.
