Cortical Correlates of Gait in Parkinson's Disease: Impact of Medication and Cueing
Source: ClinicalTrials.gov · Last updated 17 Dec 2025
Brief summary (registry, in English)
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.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Other illness
- Major musculoskeletal or neurological disorders, structural brain disease, epilepsy, acute illness or health history, other than Parkinson's Disease, significantly affecting gait and turning i.e., peripheral neuropathy with proprioceptive deficits (detected as lack of toe proprioception assessed during the neurological exam at Day 1), musculoskeletal disorders, vestibular problem, head injury, stroke.
- Montreal cognitive assessment (MoCA) score \< 21 or dementia that precludes consent to participate or ability to follow testing procedures
- Idiopathic Parkinson's Disease exclusion criteria: Parkinson plus syndromes such as progressive supranuclear palsy, multiple system atrophy, or corticobasal syndrome or implanted electrodes for deep brain stimulation (DBS), possible vascular parkinsonism, current use of dopamine-blocking agents or cholinesterase inhibitor (as may affect Prefrontal cortical activity while walking).
Other
- Severe dyskinesia that may affect quality of fNIRS.
- Inability to stand or walk for 2 minutes without an assistive device.
Who the study is looking for
- Diagnosis of idiopathic Parkinson's Disease from movement disorders neurologist with the United Kingdom Brain Bank criteria of bradykinesia with 1 or more of the following - rest tremor, rigidity, and balance problems not from visual, vestibular, cerebellar or proprioceptive conditions
- Without musculoskeletal or peripheral or central nervous system disorders (other than PD) that could significantly affect their balance and gait
- All subjects will be capable of following directions for the protocols and to give informed consent.
- Hoehn \& Yahr Levels II-III.
