PD4PD:Partnered Dance for Parkinson Disease

Exercise is often noted as an important component in a comprehensive approach to the
management of Parkinson disease (PD). Most studies of exercise have examined the effects of
short-term interventions and have tested participants on their anti-Parkinson medications.
As such, these studies have not been able to determine whether or not exercise may have a
disease-modifying effect in people with PD. The investigators recent work has shown the
potential benefits of dance as a form of exercise for individuals with PD, but, like
previous work, has only examined short-term interventions. The investigators think that
dance may be ideally suited for study over a longer period of time because dance
incorporates many of the features recommended for inclusion in PD-specific exercise programs
in a format that is known to be engaging and to enhance motivation to participate in
healthful behaviors. As such, the investigators aim to determine both the short- and
long-term effectiveness of a community-based dance program for individuals with Parkinson
disease and to determine how physical function changes over time in individuals with PD who
do not exercise as compared to those who exercise regularly. The investigators hypothesize
that:

A) participation in dance will result in improved physical function, cognitive function,
mood and quality of life in people with PD within 3 months,

B) additional improvements will be noted at 6 months as compared to 3 months,

C) improvements will be maintained at one year with continued, regular participation in a
dance class,

D) those who do not exercise will show significant functional decline over a period of one
year, a decline that will not be present in those who dance regularly.
