Autocorrelated Rhythmic Auditory Stimulations for Parkinson's Disease Patients

Patients completed 4 walking sessions of at least 10 minutes each. During each session, no auditory rhythm was given, or the rhythm of a Rhythmic Auditory Stimulation (RAS) adapted to the pace of comfort of each patient using a metronome was broadcasted via headphones. In all, 4 conditions were tested: walk with no RAS or an isochronous RAS or a random RAS or a RAS with an autocorrelated metronome rhythm.
