Abstract
[Abstract] Freezing of gait (FOG) in Parkinson’s disease (PD) rises in prevalence when the effect of medications decays. It is known
that auditory rhythmic stimulation improves gait in patients without FOG (PD-FOG), but its putative effect on patients
with FOG (PD+FOG) at the end of dose has not been evaluated yet. This work evaluates the effect of auditory rhythmic
stimulation on PD+FOG at the end of dose. 10 PD+FOG and 9 PD-FOG patients both at the end of dose periods, and 10
healthy controls were asked to perform several walking tasks. Tasks were performed in the presence and absence of
auditory sensory stimulation. All PD+FOG suffered FOG during the task. The presence of auditory rhythmic stimulation
(10% above preferred walking cadence) led PD+FOG to significantly reduce FOG. Velocity and cadence were increased,
and turn time reduced in all groups. We conclude that auditory stimulation at the frequency proposed may be useful to
avoid freezing episodes in PD+FOG.
