Estim Criteria for NMES

image1

A true NMES protocol will have ALL of the following elements:

  • Adjustable parameters
  • Range of parameters chosen are consistent with standards in the industry
  • Electrode placement consistent with anatomy and physiology that elicits an identifiable and normal movement pattern associated with swallowing (ex. submental placement)
  • Interrupted pulses mode with adequate muscle recovery time, typically 1:3 work to rest ratio
  • Ramp up of about 2 seconds
  • NMES protocol combined with task specific activities i.e the act of swallowing is specifically timed with the stimulation on cycle
  • Different parameters for different populations
  • Comfortable stimulation with amplitude sufficient to recruit motor units
  • Treatment time between 15-30 minutes 


Definition

NMES: Neuromuscular electrical stimulation is the use of electrical impulses that excite the peripheral nervous system to evoke an action potential through a transcutaneous medium. In simpler terms the electrical stimulus tells the nerves to tell the muscle (or muscles) to move.
