About this study
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.

Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 8 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jul 2015; AzTrials last refreshed its copy on 31 Oct 2026.
