Purpose: This study investigates the effects of neuromuscular electrical stimulation (NMES)-induced muscle contraction on fascial gliding between the muscle and adjacent tissues and identifies factors that affect fascial gliding.
Methods: The gliding between the epimysium of the vastus lateralis muscle and the subcutaneous tissue was measured using a diagnostic ultrasound system during the subject's knee joint was flexed passively. The deep temperature, deep blood flow, and tissue hardness of the vastus lateralis muscle were measured to identify factors contributing to the changes in fascial gliding.
