Enrollment: 13
Healthy volunteers: no

Brief summary:
To determine if PT intervention will be improved while in the "on" motor state vs. the "end-of-dose-off" motor state during the PT Intervention Visit in subjects with PD.

Detailed description:
Multicenter, outpatient trial to evaluate PT outcomes in subjects diagnosed with PD and currently using APOKYN. Those subjects who satisfy all eligibility criteria will be randomized to 2 treatment groups:

1. "APO+" (APOKYN treatment before the PT Intervention Visit) and;
2. "APO-" (APOKYN treatment withheld before the PT Intervention Visit).

The study will have:

* Baseline Assessment Visit(s) - 1 day at Investigator's clinic and PT clinic
* APOKYN Response Verification Visit - 1 day
* PT Intervention Visits - for 6 weeks
* End-of-study Assessment Visit(s) - 1 day at Investigator's clinic and PT clinic All subjects will participate in a standardized PT intervention. In both treatment groups, ALL subjects will arrive for the PT Intervention Visit in an "end-of-dose-off" motor state. The "end-of-dose-off" motor state will be achieved by the subject withholding his/her carbidopa/levodopa dose and APOKYN dose for at least 3 hours before the PT Intervention Visit. It is hypothesized that the outcome of PT will be improved when subjects are in the "on" motor state during PT Intervention visits compared with being in the "end-of-dose-off" motor state during PT Intervention visits.

Arms:
arm 1: APOKYN treatment before the PT Intervention Visit. Subjects in the "APO+" group will administer their usual dose of APOKYN at the PT clinic, as instructed by the Physical Therapist. These subjects will not take carbidopa/levodopa for at least 3 hours before or during the PT Intervention Visit. arm 2: APOKYN treatment withheld before the PT Intervention Visit. Subjects in the "APO-" group will not take carbidopa/levodopa and APOKYN for at least 3 hours before or during the PT Intervention Visit. No "rescue therapy" will be allowed during the PT. Intervention Visit. If the PT Intervention Visit needs to be stopped early, the Physical Therapist will record this along with a reason for the discontinuation.

Interventions: intervention 1: APOKYN intervention 2: Physical Therapy
Intervention descriptions: intervention 1: Subjects in the APOKYN+ group will administer his/her usual dose of APOKYN at the PT clinic, as instructed by the Physical Therapist. These subjects will not take carbidopa/levodopa for at least 3 hours before or during the PT Intervention Visit. intervention 2: All subjects will participate in a standardized PT intervention
