Spatio-temporal correction of the step is a key component of gait rehabilitation in Parkinson's disease. Walking rehabilitation techniques using visual or auditory cueing of the cadence or step length have been tested to prevent or correct the lack of consistency of the step. An auditory cue of the duration of the step, encouraging it to be extended according to patient own capacities during gait has been proposed. The cue is integrated into music and is presented in an open-loop approach.

The present study aimed to evaluate the effect of the individual music-based cueing of the step length on gait in Parkinson's disease.
