Specific brain activation patterns associated with two neuromuscular electrical stimulation protocols

Abstract The influence of neuromuscular electrical stimulation (NMES) parameters on brain activation has been scarcely investigated. We aimed at comparing two frequently used NMES protocols - designed to vary in the extent of sensory input. Whole-brain functional magnetic resonance imaging was perfo...
