Music and musical sonification for the rehabilitation of Parkinsonian dysgraphia: Conceptual framework

TL;DR

This paper explores how musical sonification, which modifies music in real-time based on movement, could improve motor control and handwriting in Parkinson's disease patients, potentially offering a novel rehabilitation approach.

Contribution

It introduces a conceptual framework for using musical sonification as a therapeutic tool to enhance motor control in Parkinson's disease, with ongoing validation for handwriting improvement.

Findings

Music enhances motor control in PD patients.

Musical sonification may improve handwriting in PD.

Real-time music modification could activate compensatory brain networks.

Abstract

Music has been shown to enhance motor control in patients with Parkinson's disease (PD). Notably, musical rhythm is perceived as an external auditory cue that helps PD patients to better control movements. The rationale of such effects is that motor control based on auditory guidance would activate a compensatory brain network that minimizes the recruitment of the defective pathway involving the basal ganglia. Would associating music to movement improve its perception and control in PD? Musical sonification consists in modifying in real-time the playback of a preselected music according to some movement parameters. The validation of such a method is underway for handwriting in PD patients. When confirmed, this study will strengthen the clinical interest of musical sonification in motor control and (re)learning in PD.
