  Purpose

The purpose of this study is to evaluate the effect of AMPYRA on a number of symptoms in Parkinson's disease. AMPYRA is a medication approved by FDA for gait dysfunction in multiple sclerosis. There are multiple studies to suggest that persons with multiple sclerosis benefit from this medication and have major improvements in gait after taking this medication. However, this medication was never studied in Parkinson's disease. This study aims to learn about possible benefits of AMPYRA in Parkinson's disease (PD).

Primary Outcome Measures:
  • gait velocity and stride length. [ Time Frame: baseline and 4 weeks ] [ Designated as safety issue: No ]
    The primary outcome measure will be the change in gait velocity and stride length as measured with by 3-dimensional gait analysis system.


Secondary Outcome Measures:
  • United Parkinson's Disease Rating Scale score(UPDRS) , [ Time Frame: baseline and 4 weeks ] [ Designated as safety issue: No ]
    change in UPDRS score (motor)

  • Freezing of Gait Questionnaire (FOGQ) [ Time Frame: baseline and 4 weeks ] [ Designated as safety issue: No ]
    change in FOGQ score

  • Timed Up and Go (TUG) score [ Time Frame: baseline and 4 weeks ] [ Designated as safety issue: No ]
    changes in time required to perform TUG.

  • Timed 25-foot Walk test (T25FW) [ Time Frame: baseline and 4 weeks ] [ Designated as safety issue: No ]
    changes in time required to perform T25FW.
