Neuromuscular electrical stimulation (NMES) which causes a muscular contraction, along with transcutaneous electrical nerve stimulation (TENS) which numbs a region, have been established protocols in PT for many decades. CenterIMTs are the only physical therapy programs advancing the use of Dr. Karen Pape’s work on Threshold electrical stimulation (TES) for the sensory development, physiologic stimulation and muscle growth in adults and children with muscle weakness.
