Sponsor: Shirley Ryan AbilityLab
Conditions: Multiple Sclerosis, Multiple Sclerosis, Relapsing-Remitting, Multiple Sclerosis, Secondary Progressive
Interventions: Acute Intermittent Hypoxia, Neuromuscular Electrical Stimulation
Countries: United States
The purpose of this study is to examine how neuromuscular electrical stimulation (NMES), may synergistically enhance corticospinal excitability in people with relapsing form multiple sclerosis (MS). This is an important intermediate step to evaluate the potential of AIH + NMES as a plasticity-priming strategy for more efficacious interventions for persons with MS. This study will measure ankle torque generation and amplitude of motor evoked potentials (MEPs) using a repeated measures study design in order to better understand the effects of AIH combined with NMES, as compared to only receiving NMES, and only receiving AIH.
