Overcoming Gait Freeze in Parkinson's Disease Using Responsive Cueing

The aim of this pilot/feasibility study is to test if delivering rhythmic vibration cues to the lower legs, specifically in response to gait defects (rather than continuously), can improve walking quality and overcome gait freezing in Parkinson's disease. During the study, people with Parkinson's disease that suffer from regular (daily) gait freezing will undertake a series of walking/activity circuits, receiving continuous cueing, responsive cueing (delivered in response to gait freezing), no cueing and no device. Vibration cueing is provided by a non-invasive wearable device prototyped at the University of Oxford, worn on the lower legs during 3 circuits. A series of walking metrics will be analysed.
