The Cochrane review recommended that future studies specify the stage of PD at which the PT is provided; functional outcomes with particular relevance to the patients, caregivers, and physicians be monitored for at least six months to determine the duration of any beneficial effects; and future studies adhere to the Consolidated Standards of Reporting Trials (CONSORT) guidelines (20). In addition, there is a need for assessment of different therapy interventions to better identify the most effective treatments. Currently, there is a marked variation in the setting and type of therapies provided. Better identification of therapies in different settings (home, outpatient, group, individual, etc.) would be useful.
