- Interventions• Control-group: no extra instruction.
• ‘Walk on the line’-group: subjects are instructed to walk on a straight line, which was projected on the middle of the between-belt gap of the treadmill. The width of the projected line was 8 cm.
• Feedback-group: in the first minute, before intervention, step width was measured. During the intervention period a number was shown on a screen in front of the subject, indicating the step width in meters. During the intervention period a decreasing percentage of initial, individual, step width resulted in positive feedback (90% during the first 15 sec; 70% during 15-30 sec; 60% during 30-45 sec; 40% during 45-60 sec). A green number indicated a step width smaller than the corresponding percentage (positive feedback), a red number indicated a step width larger than the corresponding percentage (negative feedback). Subjects were instructed ‘to keep, the number shown on the screen, green instead of red, by narrowing their step width’.

- Brief summaryBackground: Step width increases during dual-belt treadmill walking, in self-paced mode with virtual reality. Generally a familiarization period is thought to be necessary to normalize step width.
Aim: The aim of this randomised study was to analyze the effects of two interventions on step width, to reduce the familiarization period.
Methods: We used the GRAIL (Gait Real-time Analysis Interactive Lab), a dual-belt treadmill with virtual reality in the self-paced mode. Thirty healthy young adults were randomly allocated to three groups and asked to walk at their preferred speed for 5 minutes. In the first session, the control-group received no intervention, the ‘walk-on-the-line’-group was instructed to walk on a line, projected on the between-belt gap of the treadmill and the feedback-group received feedback about their current step width and were asked to reduce it. Interventions started after 1 minute and lasted 1 minute. During the second session, 7-10 days later, no interventions were given.
