Clinical Trial Summary

This study aims to address critical knowledge gaps by investigating the effects of trait conscious movement processing propensity on real-time (state) conscious movement processing propensity, postural stability, and muscle efficiency in older adults at risk of falling in Hong Kong with high and low trait conscious movement processing propensities, while standing in a challenging environment with different levels of standing task difficulties. The study results would contribute to our scientific understanding of the mechanisms of conscious movement processing in older adults while maintaining standing balance in a challenging environment. It could inform the follow-up investigations for the development of the most appropriate psychomotor standing balance re-education intervention in rehabilitation so as to mitigate the effect of conscious movement processing and the risk of falling in older adults. The findings from the proposed research could ultimately help improve the outcome of fall rehabilitation programmes and reduce the impact of falls in the older adults in Hong Kong.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Real-time (state) conscious movement processing propensity	It will be measured by the Alpha2 electrocephalogram (EEG) T3-Fz coherence.	Day 0
Secondary	Postural stability	It will be measured by the 3-D motion capture system to identify the postural sway in the unit of millimeter (mm) or the postural sway velocity in the unit of meter per second (m/s).	Day 0
Secondary	Muscle efficiency	It will be measured by the surface electromyography (EMG).	Day 0
Secondary	Functional mobility	It will be measured by the Timed 'Up & Go' (TUG) test.	Day 0
Secondary	Balance ability	It will be measured by the Berg Balance Scale. The minimum value of the scale is 0 and the maximum value is 56. Higher score represents better balance ability.	Day 0
Secondary	Fear of falling	It will be measured by the Falls Efficacy Scale International. The minimum value of the scale is 16 and the maximum value is 64. Higher score represents higher fear of falling.	Day 0
Secondary	Trait conscious movement processing propensity	It will be measured by the the Chinese version of the Movement-Specific Reinvestment Scale. The minimum value of the scale is 10 and the maximum value is 60. Higher score represents higher trait conscious movement processing propensity.	Day 0
Secondary	Perceived standing task difficulty	It will be measured by the Visual Analog Scale. The minimum value of the scale is 0 and the maximum value is 100. Higher score represents higher perceived standing task difficulty.	Day 0
