Optimizing Gait Symmetry After Stroke Using Mechanical Constraints and Sensory Feedback
What this study is about
This single-session study aims to evaluate a novel gait training protocol that integrates mechanical constraints and sensory feedback to enhance paretic leg propulsion in individuals post-stroke. The study will include 15 individuals who have experienced a stroke and 15 healthy adults, each aged 20 years or older.
View original scientific description
This single-session study aims to evaluate a novel gait training protocol that integrates mechanical constraints and sensory feedback to enhance paretic leg propulsion in individuals post-stroke. The study will include 15 individuals who have experienced a stroke and 15 healthy adults, each aged 20 years or older. Participants will walk on both tied-belt and split-belt treadmills under various training conditions, including backward-directed resistance (applied at the pelvis, ankle, or both) and real-time sensory feedback (visual, auditory, or combined). These interventions will be applied individually and in combination to identify the most effective environment for promoting symmetrical gait patterns. Each session will last approximately two hours. The equipment used is non-invasive, and the risk to participants is minimal.
Interventions
BEHAVIORAL
Treadmill Walking with Split-Belt and/or Tied-Belt Conditions
Participants will walk on an instrumented treadmill under split-belt and/or tied-belt conditions depending on their walking capacity. The belt speeds will be adjusted to facilitate locomotor adaptation and evaluate propulsion symmetry.
BEHAVIORAL
Mechanical Resistance (Pelvis and/or Ankle) depending on participant's walking capacity
Participants will walk on a treadmill (Split-belt and/or Tied-belt) with backward-directed resistance applied at the pelvis, ankle, or both. The resistance is used to challenge paretic leg propulsion and assess adaptive gait responses.
BEHAVIORAL
Sensory Feedback Training
Real-time feedback-visual, auditory, or combined-will be provided based on the propulsive force generated during split-belt and/or tied-belt treadmill walking, with or without mechanical resistance.
Primary outcome measures
Change in Paretic Leg Propulsive Force
Time frame: Within a single session (approximately 2 hours)
Peak anterior ground reaction force of the paretic leg will be measured using an instrumented split-belt treadmill . Changes in propulsive force under different treadmill and resistance/feedback conditions will be analyzed to evaluate improvements in gait symmetry.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
