Brief Summary

A split-belt treadmill (SBT) is a treadmill with two belts, whereby each leg can be driven at a different speed. Previous work by the investigators showed that one session of SBT training improved turning while multi-tasking and reduced FOG in PwPD tested in the laboratory. However, subsequent work raises questions as to whether treadmill improvements following repeated SBT training generalize to overground situations in the long term. Therefore, in this study, the investigators will perform a four-week SBT intervention with added practice of everyday turning scenarios (SBT+CP) or placebo exercise (SBT+PL), and study its effects on FOG in both the laboratory and at home.

Outcome Measures

Primary Outcomes (2)

  • Percentage Time Frozen during turning in place

    Percentage Time Frozen scored from video of rapid alternating full turns in place. Based on earlier work showing immediate effects of SBT training on FOG during this task.

    up to 8 weeks post intervention

  • Time to complete Timed Up and Go (TUG)

    Overall time to complete the Timed Up and Go task. The training is expected to improve multiple transitions between straight walking and turning and should be reflected in the overall task time.

    up to 8 weeks post intervention

Secondary Outcomes (2)

  • Percentage Time Frozen over all FOG-provoking tasks

    up to 8 weeks post intervention

  • Percentage Time Frozen over 1-week free-living monitoring

    up to 8 weeks post intervention
