Split-Belt Treadmill for Stroke

This trial explores a new method to help stroke survivors improve their walking abilities using a special treadmill called the Split-Belt Treadmill. This treadmill is unique because each leg can move at different speeds, potentially helping people learn to walk more evenly. Researchers aim to determine how much training participants can handle in one session without excessive fatigue or discomfort. This study targets individuals who have experienced their first stroke and are still recovering within one week to three months after the event. The goal is to enhance rehabilitation methods so stroke survivors can regain mobility and improve their quality of life. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants a chance to be among the first to experience this innovative approach.

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Research has shown that split-belt treadmill (SBT) training is generally well-tolerated by stroke survivors. Studies have found that it can improve walking speed and make steps more even, which are important recovery goals. For example, one study noted that participants walked faster after training, with even more progress a month later. Another study demonstrated that SBT helps people walk more evenly, supporting stroke recovery.

Researchers are excited about the split-belt treadmill for stroke rehabilitation because it offers a novel approach to improving walking abilities post-stroke. Unlike traditional rehabilitation methods that focus on uniform gait training, this treadmill can adjust the speed of each belt independently, tailoring the therapy to each leg's specific needs. This individualized treatment could enhance neural adaptation and recovery more effectively than standard methods, potentially leading to quicker and more robust improvements in walking for stroke patients.

Research has shown that split-belt treadmill (SBT) training can help stroke survivors improve their walking. One study found that participants increased their walking speed from 0.71 meters per second to 0.81 meters per second after training, with a further increase to 0.86 meters per second a month later. Another study found that SBT training improved step symmetry by 27.3% without reducing speed. SBT training also reduced uneven step length from 21% to 9%, and further to 7% after a month. Overall, SBT training has effectively helped stroke survivors walk more evenly and improve leg function. Participants in this trial will join a dose escalation study to further evaluate the effectiveness of SBT training.¹²³⁴⁶
