Conscious Movement Processing, Postural Stability and Muscle Efficiency in Older Adults
February 27, 2024 updated by: The Hong Kong Polytechnic University
The Effects of Conscious Movement Processing on Postural Stability and Muscle Efficiency While Standing in a Challenging Environment by Older Adults at Risk of Falling in Hong Kong: Implications for Rehabilitation.
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.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
65 years to 99 years (Older Adult)
Accepts Healthy Volunteers
Yes
Sampling Method
Non-Probability Sample
Study Population
The recruitment of older adult participants (N = 132) will take place at collaborating rehabilitative and elderly community centres in Hong Kong through convenience sampling.
Potential participants will be screened for eligibility according to the inclusion and exclusion criteria.
Description
Inclusion Criteria:
- 65 years old or above;
- able to stand independently without a walking aid.
Exclusion Criteria:
- a history of any major cerebrovascular and/or neurological disorders (e.g., stroke, Parkinson's disease);
- a history of a major fall event within the past year;
- the existence of an unstable medical or mobility condition that could affect safety in this study;
- a score of 23/30 or below in the Chinese version of Mini-Mental State Examination (MMSE-C);
- a static visual acuity poorer than 20/40 vision (examined by the Tumbling-E eye chart).

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
High Reinvestor Group (HRG)
Participants will be invited to complete a series of standing balance trials.
The trials will involve participants standing in three different positions on a foam surface (i.e., Airex balance pad elite with a dimension of 16.1" width x 19.7" length x 2.4" height, or equivalent).The three different standing positions will be: wide-base standing on foam (WBF), narrow-base standing on foam (NBF), and tandem standing on foam (TAF) (i.e., low-level of task difficulty, moderate-level of task difficulty, and high-level of task difficulty, respectively).
For each standing position, participants will be required to perform two consecutive standing balance trials, with a 1-minute rest break in between.
|
The three different standing positions will include wide-base standing on foam (WBF) with low-level of task difficulty, narrow-base standing on foam (NBF) with moderate-level of task difficulty, and tandem standing on foam (TAF) with high-level of task difficulty.

|
Day 0
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Postural stability
Time Frame: Day 0
|
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
|
Muscle efficiency
Time Frame: Day 0
|
It will be measured by the surface electromyography (EMG).
|
Day 0
|
Functional mobility
Time Frame: Day 0
|
It will be measured by the Timed 'Up & Go' (TUG) test.
|
Day 0
|
Balance ability
Time Frame: Day 0
|
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
|
Fear of falling
Time Frame: Day 0
|
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
|
Trait conscious movement processing propensity
Time Frame: Day 0
|
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
|
