How Neuromuscular Electrical Stimulation Works?

Neuromuscular electrical stimulation (NMES) refers to the use of electrical impulses to elicit muscle contraction. It falls under electrotherapy, the use of electrical energy in medical therapy. This therapy is also used to control dysphagia. 

During NMES, a special device is used to deliver a small electric current to the face or neck of the patient. The electrical current is delivered through specially placed electrodes on the patient’s face and/or neck. The electrical current stimulates the nerves and muscles responsible for swallowing.

This stimulation improves the strength, coordination, endurance, sensory feedback, and timing in the muscles involved in eating, drinking, and swallowing. While the electrical stimulation is being delivered, a certified therapist helps patients train their muscles with special exercises.

Over time, the patient’s muscles are trained how to properly swallow food and drink. The main goal of electrical stimulation therapy is to strengthen weak muscles and to help children gain control of their oral motor skills.

Hence, neuromuscular electrical stimulation uses a safe, non-invasive, low-frequency current that is applied to the muscles through electrodes on the skin.  Electrical stimulation excites the nerves that innervate desired muscles, causing them to contract.
