- Registration Number
- NCT05690308
- Lead Sponsor
- University Ghent
- Brief Summary
Falls during walking are common in people with Parkinson's Disease (PD). Fall risk can be attributed in part to the loss of automaticity in walking and an increased reliance on sensory cues, such as the input from the balance organ. In this project the investigators want to assess the effectiveness of rehabilitation training aiming to improve this vestibular input. The effects of a visual perturbation training in a virtual reality environment will be compared to conventional treadmill training.
- Detailed Description
Fifty participants (50-65 years) with idiopathic PD (Hoehn \& Yahr scale 2-3) will be randomly assigned to the intervention group receiving four weeks of VPT in a VR environment using the Gait Real-time Analysis Interactive Lab system (GRAIL) or a control group receiving four weeks of regular treadmill training. Primary outcome measures are spatio-temporal outcome parameters of gait and dynamic stability (gait speed, stride time/length, cadence, step-to-step variability, step width variability and trunk sway), and self-reported falls, and will be recorded at all testing phases (pre-test, after baseline, after intervention and after detraining). Secondary outcome measures will include assessments of central and peripheral vestibular function (Cervical and ocular Vestibular Evoked Myogenic Potentials) for correlation with the primary outcome measures. The secondary outcomes will be recorded at pre-testing and directly after the intervention phase.

Group Intervention Description Experimental visual perturbation treadmill training Visual perturbation treadmill training Participants assigned to the experimental intervention will receive 6 weeks, 2x per week of visual perturbation treadmill training using the GRAIL system. This will consist of maximum 30 minutes of walking on the treadmill while translations and rotations of the projected environment are applied. Control treadmill training Regular treadmill training Participants assigned to the control intervention will receive 6 weeks, 2x per week of treadmill only training. This will consist of maximum 30 minutes of walking on the treadmill without any visual perturbations.
