The Neural Mechanisms of Split-belt Treadmill Adaptation in People With

Status Recruiting

Clinical Trial Summary

Majority of people with multiple sclerosis experience difficulty with balance and mobility, leading to an increased risk of falls. The goal of this clinical trial is to learn about brain activity during walking adaptation in people with multiple sclerosis. Also, this clinical trial will test a form of nerve stimulation to see if it can improve walking performance. The main questions it aims to answer are: - What areas of the brain are the most active during walking adaptation? - Can nerve stimulation make walking adaptation more effective? Participants will walk on a treadmill where each leg will go a different speed which will create walking adaptation. At the same time, brain scans will occur. There will be two sessions of walking adaptation, one with nerve stimulation, and one without nerve stimulation. Researchers will compare people with multiple sclerosis to healthy young adults to see if there are differences in brain activity.

Clinical Trial Description

Most people with MS (PwMS) experience significant gait asymmetries between the two legs leading to an increased risk of falls and musculoskeletal injury. The objective of this study is to investigate the neural mechanisms of gait adaptation and the effects of transcutaneous electrical nerve stimulation (TENS) on adaptability during split-belt treadmill training in PwMS. Our hypothesis is that TENS will strengthen sensorimotor integration via amplified afferent signaling, thereby enhancing adaptation, and further improving gait symmetry chronically. Functional near-infrared spectroscopy (fNIRS) will be used during a split-belt treadmill training paradigm to assess cortical activation during gait adaptation. Additionally, the effect of split-belt treadmill training coupled with TENS on gait adaptability in PwMS will be tested with experimental and a sham TENS split-belt treadmill sessions. Cortical activation and the effect of TENS on gait adaptability will be compared between young neurotypical adults and PwMS to assess differences that can be attributed to multiple sclerosis. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
