NIBS and Dual-task Walking After Stroke

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03442868

Brief Summary:
The study aims to identify neural locus critical for dual-task walking (walking and talking) in individuals with stroke. To achieve this aim, the investigators apply repetitive transcranial magnetic stimulation (rTMS) to different parts of the brain and evaluate the effects of brain stimulation on dual-task walking speed.

Condition or disease Intervention/treatment Phase
Stroke Device: high frequency rTMS Not Applicable

Detailed Description:
This study will enroll 12 individuals with a stroke at least 6 months ago. Participants will be tested across 3 sessions and each session will be approximately 1 week apart from each other. During testing, participants will be asked to walk under two conditions: single- and dual-task conditions. Under the single-task condition, participants walk on a instrumented mat such that their gait performance will be captured. Under the dual-task condition, participants walk on the mat while performing a counting backward task. The walking assessment is followed by a 12 minute non-invasive brain stimulation using high frequency rTMS. Another walking assessment will be conducted right after the brain stimulation session. High frequency rTMS will be applied to different neural loci, namely primary motor cortex, supplementary cortex, and dorsolateral prefrontal cortex. The walking speed under two different conditions will be compared before and after brain stimulation to different neural loci.

Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Efficacy of Non-Invasive Brain Stimulation on Dual-Task Walking After Stroke: A rTMS Study
Actual Study Start Date : October 19, 2016
Actual Primary Completion Date : December 31, 2018
Actual Study Completion Date : December 31, 2018

Arm Intervention/treatment
Experimental: High frequency rTMS
High frequency rTMS will be applied to different neural loci based on the randomized sessions.
Device: high frequency rTMS
Participants receive 16 minutes (5Hz, 24 10-second trains with a inter-train interval of 30s) of high frequency rTMS applied to either primary motor cortex, supplementary motor areas and dorsolateral prefrontal cortex at different sessions. Walking performance is evaluated before and after the brain stimulation.

Primary Outcome Measures :
  1. change in gait speed [ Time Frame: before and 10 minutes after the non-invasive brain stimulation ]
    gait speed in m/s will be captured using GaitRite

Secondary Outcome Measures :
  1. change in step lengths [ Time Frame: before and 10 minutes after the non-invasive brain stimulation ]
    Step lengths in m will be captured using GaitRite

  2. change in single support times [ Time Frame: before and 10 minutes after the non-invasive brain stimulation ]
    Single support times (in % of gait cycle) will be captured using GaitRite

  3. change in counting task performance [ Time Frame: before and 10 minutes after the non-invasive brain stimulation ]
    number of correct responses in counting backward task
