Brain scans may reveal why some stroke survivors walk better after exercise
NCT ID NCT07663292
First seen Jun 27, 2026 · Last updated Aug 21, 2026 · Updated 2 times
Summary
This study investigates why some chronic stroke survivors with slow walking speed improve after high-intensity interval training (HIIT) while others do not. Participants will undergo 12 weeks of supervised cycling sessions, along with MRI brain scans and walking tests before and after the program. The goal is to find brain-based markers that predict who will respond to exercise therapy, potentially leading to more personalized rehabilitation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- high-intensity interval training (HIIT) cycling
- What this could lead to
- If successful, this could help doctors predict which stroke survivors will benefit most from exercise therapy, personalizing rehab.
- What could go wrong
- This is an early-stage observational study with only 55 participants. It may not identify clear brain markers, and results may not apply to all stroke survivors.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * chronic left or right subcortical stroke as defined by 6 months or more after a cardiovascular accident * lower extremity motor impairment due to stroke that causes a walking speed of less than 0.6 m/s during a 10m walk, * age 18-80 years old, and * Screen pass of the Stress test or Physician sign-off from the participant's health care team that they are cleared for a 12 week exercise intervention Exclusion Criteria: * MRI contraindications, including implanted cardiac pacemakers and severe claustrophobia * any neurodegenerative condition other than stroke that may lead to lower extremity impairment * visual or auditory impairment that may hinder study procedures, and * any medical condition that would preclude from participation in a physical exercise intervention program.
