The Effects of Music and Dance Training on Beat Perception and Production Abilities in Parkinson’s Disease
Hi! My name is Prisca Hsu and I am an undergraduate student pursuing an Honors Specialization in Neuroscience at Western University. Over the past year, I have been involved with EEG and behavioural techniques to assess human beat perception and production abilities in the Grahn Lab. This summer, I gathered beat perception and production (BAT) data from 450 participants across a variety of walking and music studies. I analyzed the data in hopes of finding interesting patterns and tendencies across different participant demographics and levels of music/dance training. Special thanks to Dr. Emily Ready for her guidance on this project!

The Effects of Music and Dance Training on Beat Perception and Production Abilities in Parkinson’s Disease
Whether through clapping, tapping or dancing, humans naturally perceive and move to a musical beat. Yet, the accuracy of this seemingly effortless behavior varies widely across individuals. Beat perception and production accuracy are positively impacted by music and dance training but negatively impacted by neurological changes in Parkinson’s Disease (PD). Rehabilitative strategies such as rhythmic auditory stimulation use rhythm synchronization tasks to cue motor performance in hopes of remediating motor impairments related to PD. In this study, we aim to assess whether the positive effects of music training in healthy adults also apply to PD patients and how previous music and dance training could potentially mitigate their motor impairments. We used the Beat Alignment Test (BAT) to assess beat perception and production abilities among 450 participants. These participants include 278 healthy younger adults, 132 healthy older adults and 40 people with early-stage PD across varying levels of music and dance training. We found that people with early-stage PD demonstrated no perception deficits but were impaired on beat production compared to healthy adults. The PD group with over three years of music training demonstrated more accurate beat production abilities compared to the PD group with minimal music training. These results suggest that music training could be associated with more accurate motor behaviors and a lowered degree of motor impairment in early-stage PD.
