Outcome Measures

Primary Outcomes (5)

  • Change in Static Balance as Recorded Using Dynamic Posturography With the Sensory Organization Test (SOT 1-3)

    Sensory organization test (SOT) is a form of posturography. which is designed to assess quantitatively an individual's ability to use visual, proprioceptive and vestibular cues to maintain postural stability in stance. The SOT measures sway during 6 scenarios. In scenarios 1-3 the base is stable and eyes are open, then closed, and then the visual surround moves. SOT 1-3 is an average measurement of equilibrium - the average center of gravity sway for each condition. It generates a score of 0 (fall) up to 100 for each scenario and an overall composite score. Change score is measurement at 16 weeks minus measurement at baseline.

    Baseline, 16 weeks

  • Change in Ambulatory Balance Measured by Instrumented Timed up and go (iTUG) Turn Duration

    This is a test that measures ambulatory balance and mobility. The instrumented timed up and go (iTUG) is an average time (seconds) of three trials that involve the participant arising from a chair, walking 25 feet turning around, walking back to the chair, and sitting down. The turn duration is the average time to turn at the end of the 25 foot walk. Longer duration of time (seconds) indicates more rigidity, a proxy measure for "ON" time in Parkinson's disease. Change score is measurement at 16 weeks minus measurement at baseline.

    Baseline and 16 weeks

  • Change in Strength as Recorded by Measuring Knee Flexion Using Biodex (Total Work)

    Defined as the total muscular force output for the repetition with the greatest amount of work. The equation for work is: W = F x D. Change score is measurement at 16 weeks minus measurement at baseline.

    Baseline, 16 weeks

  • Change in Dynamic Balance as Recorded Using Dynamic Posturography With the Sensory Organization Test (SOT 4-6)

    Sensory organization test (SOT) is a form of posturography. which is designed to assess quantitatively an individual's ability to use visual, proprioceptive and vestibular cues to maintain postural stability in stance. The SOT measures sway during 6 scenarios. In 4-6 the base moves and the subject has eyes open, then closed, then the visual surround moves. SOT 4-6 is an average measurement of equilibrium - the average center of gravity sway for each condition. It generates a score of 0 (fall) up to 100 for each scenario and an overall composite score. Change score is measurement at 16 weeks minus measurement at baseline.

    Baseline, 16 weeks

  • Change in Strength as Recorded by Measuring Knee Extension Using Biodex (Total Work)

    Defined as the total muscular force output for the repetition with the greatest amount of work. The equation for work is: W = F x D. Change score is measurement at 16 weeks minus measurement at baseline.

    Baseline, 16 weeks

Secondary Outcomes (3)

  • Change in Cognition (Trail Making Test B-A)

    Baseline, 16 weeks

  • Change in Quality of Life as Recorded Using Quality of Life Scales (PDQ39)

    Baseline, 16 weeks

  • Change in Parkinsonism as Measured by the UPDRS

    Baseline, 16 weeks
