Improvement in upper-limb UPDRS motor scores following fast-paced arm exercise: A pilot study.

Background: The symptoms of patients with Parkinson's disease (PD) have been shown to improve when they perform fast-paced rhythmic cycling movements with their lower limbs.

Objective: Our goal in this pilot experiment was to test the feasibility and the benefits of a short exercise program involving fast-paced rhythmic movements of the upper limb for patients with PD.

Methods: We used an experimental procedure that elicits large, fast-paced movements by the participants without the direct instructions to do so by the experimenter.
