The Influence of Vibrotactile Stimulation on Self-selected Walking Speed in People With Parkinson's Disease

The study tests whether a smart shoe (NUSHU) that provides vibrotactile stimulation can improve walking speed in people with Parkinson's disease. Sixteen participants complete two short walking tests-with and without vibration-to compare gait speed, cadence, stride length, usability, and safety. It is a low-risk pilot study meant to generate first evidence for future research.

Inclusion criteria: * A medically confirmed diagnosis of Parkinson's disease on the physiotherapy prescription. * Stable medication for at least four weeks (no change in dopaminergic therapy). * The ability to walk at least 200 metres without stopping. * Minimum age: 18 years * Sufficient knowledge of German to understand the study information and complete the questionnaires. * Written informed consent form Exclusion criteria: * Atypical or secondary Parkinsonism * Sensory disturbances in the feet (e.g. polyneuropathy). * Other neurological, orthopaedic or internal medical conditions that significantly affect walking * Cognitive impairments that interfere with understanding the study information or following instructions
