Overground versus treadmill walking in Parkinson's disease: Relationship between speed and spatiotemporal gait metrics.

ABSTRACT:

Background

Treadmills provide a safe and convenient way to study the gait of people with Parkinson's disease (PD), but outcome measures derived from treadmill gait may differ from overground walking.

Objective

To investigate how the relationships between gait metrics and walking speed vary between overground and treadmill walking in people with PD and healthy controls.

Methods

We compared 29 healthy controls to 27 people with PD in the OFF-medication state. Subjects first walked overground on an instrumented gait walkway, then on an instrumented treadmill at 85%, 100% and 115% of their overground walking speed. Average stride length and cadence were computed for each subject in both overground and treadmill walking.

Results

Stride length and cadence both differ
