ABSTRACT

Background Impaired gait adaptability is one of the major causes of falls among older adults by producing inappropriate gait adjustments in cluttered environments. Training programs designed to improve gait adaptability behavior in a systemic approach may prevent falls in older adults. Recently, the technology of virtual reality appears as a relevant gait training tool based on its training implementation potential. Objective The present study was designed to compare the effectiveness of a virtual reality gait training program (VR group) for improving gait adaptability behavior and, thus, reducing risk of falls relative to a conventional training program of Nordic walkway (NW group). We hypothesize that the virtual reality gait training program will lead to greater gait adaptability improvements. Method The protocol describes a randomized controlled trial with pre-tests, post-tests, retention-tests and follow-up. Forty healthy independent living community dwellers participants (65–80 years) will be allocated, after a general medical examination, in the VR or the NW group for a training program of six weeks. Primary outcome related to gait adaptability capacities and acceptance of the virtual reality device will be assessed in pre- and post-intervention and after one month after the completion of the training program (retention). A follow-up will be done during the 12 months after the completion of the gait training program. Results Data collection will begin in September and the first results are expected in 2025. Conclusions This study will demonstrate the relative relevance of a gait training program in virtual reality versus a conventional one for improving gait adaptability behavior in healthy older adults and, thus, prevent fall.
