Rhythmic movement helps Parkinson patients restore the balance between positive and negative symptoms. Patients who participate in a specially designed Dance for PD (http://danceforparkinsons.org/) class for people with Parkinson (PwP) like the one at the Mark Morris Dance Center, pictured here, report that moving to music helps them regain muscle control. Exercise, including tai chi and boxing, also reinforces treatments directed toward replacing depleted dopamine.
