Dance as therapy for individuals with Parkinson disease.

Parkinson disease (PD) is a progressive, neurodegenerative movement disorder that is often accompanied by impaired balance and walking and reduced quality of life (QoL). Recent studies indicate that dance may be an effective alternative to traditional exercise for addressing these areas of concern to individuals with PD. This review summarizes the relatively scant literature on the benefits of dance for those with PD, discusses what is currently known with respect to appropriate dosing of dance interventions, and speculates upon potential mechanisms by which dance may convey benefits. There is a clear need for additional research using larger sample sizes to examine the potential long-term effects of dance for those with PD.
