1.Primary Outcome
Title MDS-UPDRS Motor III Score
Hide Description The Movement Disorder Society-Unified Parkinson's disease Rating Scale (MDS-UPDRS) Motor III Score is a subscale of the MDS-UPDRS. The MDS-UPDRS III is the sum of 33 scores that evaluate Parkinson's disease motor symptoms on a scale from 0 to 4 points. A score of 0 indicated no symptom is present and a maximum score of 4 indicates the most severe symptom, the total scale range is 0-132, where higher scores indicate more severe symptoms. The primary outcome is the change in total motor subscale score in the MDS-UPDRS from baseline versus the three end of treatment (EOT) assessments.
Time Frame Change from baseline over 16 weeks

2.Primary Outcome
Title Trail Making Test
Hide Description The Trail Making test is a test of executive function and the primary outcome is total test time. The total time that it takes to complete the test was recorded at baseline and then after the end of treatment. Test time recording begins with the start of the test and ends when the test is completed. Longer times indicate worse executive function. The outcome is the change in test time on the trail making test from baseline to the end of treatment (EOT) assessment.

3.Primary Outcome
Title Number of Participants With Increased Motor Cortex and Thalamus Connectivity
Hide Description The primary outcome measure will number of patients that increased their connection between the motor cortex and the thalamus. The functional connection was assessed using functional magnetic resonance imaging. The outcome measure was change in connectivity from baseline to end of treatment.
Time Frame Change from baseline to end of treatment
Hide Outcome Measure Data
Hide Analysis Population Description
A subgroup of participants from only the exercise groups were analyzed for this outcome measure, as not all participants in this study received functional MRI's. The No Exercise group was not included in this subgroup analysis and did not receive MRI.
Arm/Group Title Forced Exercise Voluntary Exercise No Exercise
Hide Arm/Group Description:
Forced exercise: Exercise on a stationary cycle, controlled by a motor to augment voluntary rate by 35%
Voluntary exercise: Exercise on a stationary cycle without motor assistance
No-exercise/control: No exercise intervention is given. This group serves as a control group.
