Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Gait retraining.
The participant will receive real-time visual biofeedback regarding the frontal plane lean of their trunk as they walk along a level indoor walkway wearing their own closed-in footwear. The feedback will be projected onto a screen at the end of the walkway in the form of a moving line representing the magnitude of their trunk lean in real-time along with a shaded zone representing a target magnitude of lean they should try to avoid. Their baseline trunk lean will be calculated using marker-based three-dimensional motion analysis during normal walking. They will then be instructed to use this feedback to modify their movement patterns to reduce the magnitude of trunk lean as they walk by 30% from their average baseline mediolateral excursion (as represented by the shaded zone). This intervention will be facilitated by an Exercise Scientist/Biomechanist and delivered in a single session at the Biomechanics laboratory, Australian Catholic University, Brisbane, Queensland, will last 10-20 minutes and will be completed at a self-selected walking pace. Outcome data will be collected across two sessions, with Session 1 consisting of: (i) Baseline walking trials (at least 5 trials), (ii) walking trials during the delivery of the intervention (at least the last 5 trials of the intervention), (iii) 5 minutes post intervention (at least 5 trials), and Session 2 consisting of (iv) follow-up walking trials (at least 5 trials). The exact number of trials under each condition will be recorded manually by the session facilitator.

Statistical methods / analysis
The primary research question seeks to determine differences in the average mediolateral trunk lean between the 4-time points (i: Baseline walking; ii: Intervention; iii: Post-intervention; iv: 1-week follow up), using a Repeated Measures ANOVA.

Sample size was estimated using G-Power (Version 3.1.9.2) based on a Repeated Measures ANOVA study design. As no previous data was available regarding changes in mediolateral trunk lean, the default medium effect size was selected (ES = 0.25). For a significance level of 0.05 and power of 80% the estimated sample size is n=24. To account for participant drop out between sessions we will aim to recruit 30 participants.
