Locomotor training in people with Parkinson disease.

The purpose of this article is to consider the role of the physical therapist in locomotor training for people with Parkinson disease. The ways in which disease progression, medication status, environmental conditions, individual factors, and the goals of locomotor tasks contribute to clinical decision making are explored. Using the International Classification of Functioning, Disability and Health, gait training will be considered in relation to impairments of body structure and function, activity limitations, and participation restrictions in people who are newly diagnosed through to those with end-stage disease. Based on the principles of neural adaptation and clinical research findings, practical suggestions are made on how to provide the most efficient and effective physical therapy services at different stages of Parkinson disease.
