Brief Summary

The primary purpose of this project is to determine the preliminary effectiveness of protective step training to improve balance and reduce falls in people with Parkinson's disease (PD) and postural disturbances. A secondary purpose is to understand which baseline patient characteristics predict responsiveness to treatment. By informing 1) the effectiveness of a promising rehabilitative intervention, and 2) the selection of the participants that will be most responsive to treatment, these data may enhance clinicians' ability to treat balance disturbances in people with PD. Importantly, protective step training, described in this proposal, can be quickly deployed in the clinic at minimal cost. Therefore, if shown to be effective via this and subsequent trials, this approach can be easily integrated into care, immediately impacting a large number of people with PD.

Outcome Measures

Primary Outcomes (1)

  • Stepping performance, measured as Margin of Stability (MOS)

    MOS: Distance between the extrapolated center of mass and base of support at first foot contact after the slip

    Change across baseline period (2 weeks), compared to change across intervention period (2 weeks)

Secondary Outcomes (4)

  • Stepping performance, measured as First Step Length

    Change across baseline period (2 weeks), compared to change across intervention period (2 weeks)

  • Stepping performance, measured as First Step Latency

    Change across baseline period (2 weeks), compared to change across intervention period (2 weeks)

  • Cognition, measured as the total score on the "SCales for Outcomes in PArkinson's disease-COGnition" (SCOPA-COG)

    Baseline

  • Structural brain connectivity between the cortex (supplementary motor area), and basal ganglia (striatum)

    Baseline

Other Outcomes (3)

  • Retention of stepping improvement (measured as Margin of Stability; MOS) over 2 months

    Change in MOS score from Baseline to Follow-up (10 weeks between collections)

  • Generalization of stepping improvement (measured as Margin of Stability; MOS)

    Change in MOS score from Baseline 2 to Post (2 weeks between collections)

  • Fall frequency

    Change in the number of falls during baseline (2 months) and follow-up (2 months) periods.

Study Arms (1)

Multi-baseline Step Training

EXPERIMENTAL

Participants will be assessed before and after a 2-week baseline period, and again before and after a 2 week "protective step training period. Participants will also be assessed 2 months later at a follow-up visit.

Behavioral: Protective Step Training

Interventions

Participants will undergo 6, 1 hour visits (over the course of 2 weeks) where they will be exposed to repeated slips on a treadmill.
