简要总结
This study will be a pilot randomized controlled trial, to investigate the effectiveness of an external focus training on visuomotor performance while comparing with an active control group.
详细描述
All eligible participants will be randomly divided into two groups: external focus gait training group (EXT) and active control group (CON). All participants will complete two assessment sessions: at baseline (T0) and immediately following the completion of all training sessions (T1). A total of twelve training sessions (about 45 minutes per session), held twice a week for six weeks, would be provided to participants in both training groups.

结局指标
主要结局
Gait stability - variability of stride time
时间窗: baseline (pre-intervention), immediately after intervention (post-intervention)
measured by a 3-D motion capture system; stride time is defined as the interval between two consecutive heel strikes of the same foot; the variability measure is represented by the coefficients of variation (CV) \[(standard deviation/mean) × 100\]
Gait stability - variability of stride length
时间窗: baseline (pre-intervention), immediately after intervention (post-intervention)
measured by a 3-D motion capture system; stride length is defined as anterior-posterior (A-P) distance between two consecutive heel strike positions of the same foot; the variability measure is represented by the coefficients of variation (CV) \[(standard deviation/mean) × 100\]
Gait stability - variability of step width
时间窗: baseline (pre-intervention), immediately after intervention (post-intervention)
measured by a 3-D motion capture system; step width is defined as medial-lateral (M-L) distance between two consecutive heel strike positions of the opposite feet; the variability measure is represented by the coefficients of variation (CV) \[(standard deviation/mean) × 100\]
Visual search behaviours - location of fixation
时间窗: baseline (pre-intervention), immediately after intervention (post-intervention)
measured by a wireless eye tracker; recorded the location that the gaze is fixated on
Visual search behaviours - the number of fixation
时间窗: baseline (pre-intervention), immediately after intervention (post-intervention)
measured by a wireless eye tracker; recorded the number of times the gaze is fixated on each area of interest
Visual search behaviours - fixation duration
时间窗: baseline (pre-intervention), immediately after intervention (post-intervention)
measured by a wireless eye tracker; recorded the duration that the gaze is fixated on each area of interest
次要结局
- Functional balance and gait(baseline (pre-intervention), immediately after intervention (post-intervention))
- Falls efficacy(baseline (pre-intervention), immediately after intervention (post-intervention))
- Conscious movement processing(baseline (pre-intervention), immediately after intervention (post-intervention))
- Functional balance(baseline (pre-intervention), immediately after intervention (post-intervention))
- Functional mobility(baseline (pre-intervention), immediately after intervention (post-intervention))
