Interventions

  • Personalized tactile cueing — DEVICE
    We will use as an external cue, a system of tactile cueing with the purpose of enhancing proprioceptive inputs, in the form of real-time(synchronized to the gait heel strike), closed-loop tactile feedback signaling left and right stance times while walking. Also, the participants use the same system cueing in closed-loop feedback during daily life for one week.
  • Fixed tactile cueing — DEVICE
    We will use as an external cue, a system of tactile cueing with the purpose of enhancing proprioceptive inputs, in the form of real-time, open-loop(fixed rhythm) tactile feedback signaling left and right stance times while walking. Also, the participants use the same system cueing in open-loop feedback during daily life for one week.

Study Details

The purpose of the study is to determine the effects of a novel, personalized, tactile cueing system on gait automaticity. The researchers hypothesized that step-synchronized tactile cueing will reduce prefrontal cortex activity (improve automaticity) and improve gait variability (as well as gait speed). The researchers predict that improved automaticity with improved gait variability will be associated with increased activation of other than prefrontal cortical areas while walking (i.e., sensory-motor). To determine the effects of cueing, 60 participants with PD from will be randomized into one, of two, cueing interventions: 1) personalized, step-synchronized tactile cueing and 2) tactile cueing at fixed intervals as an active control group. In addition, the researchers will explore the feasibility and potential benefits of independent use of tactile cueing during a week in daily life for a future clinical trial. This project will characterize the cortical correlates of gait automaticity, the changes in gait automaticity with cueing in people with Parkinson's Disease, and how these changes translate to improvement in gait and turning. The long-term goal is to unravel the mechanisms of impaired gait automaticity in Parkinson's Disease.
