Measure
Parkinson Group
n=29 Participants
People living with Parkinson disease walking with and without rhythmic cues. Mentally singing: All participants (people with PD and age-matched controls) sing their song in their head and match their footfalls or finger tapping to the beat. Music: All participants (people with PD and age-matched controls) listen to their song and match their footfalls or finger tapping to the beat. Uncued: no music and no singing
Healthy Control Group
n=29 Participants
Healthy controls walking with and without rhythmic cues. Mentally singing: All participants (people with PD and age-matched controls) sing their song in their head and match their footfalls or finger tapping to the beat. Music: All participants (people with PD and age-matched controls) listen to their song and match their footfalls or finger tapping to the beat. Uncued: no music and no singing

SECONDARY outcome

Timeframe: Baseline

Population: Results are presented separately for each group in each condition (uncued, music, mental singing).

We analyzed the Blood Oxygen Level Dependent (BOLD) signal in the brain to determine where there were areas of significant changes in brain activity, relative to rest, when participants were moving with no cue (uncued), moving to the beat during self cueing (mental singing) and moving to the best during external cueing (music). BOLD values are reported are Beta weights. Positive values indicate an increase in activity relative to rest and negative values indicate a decrease in activity relative to rest.
