When these impulses pass a threshold, the action potential is fired and something happens. Action potential is what we call it when a neuron (cell in the nervous system) transmits information (electrical impulses) along an axon (the thread-like conduit leading away from the neuron body, toward other cells). How Exactly Does E-stim Work?ĮMS therapy mimics the action potential that comes from the central nervous system. For example, a long-distance runner might use e-stim therapy as a complementary technique to train muscle fibers to resist fatigue.

Some studies have indicated that e-stim can be targeted to create contractions in different types of muscle fibers, allowing athletes (with the guidance and help of professional sports therapists) to train injured or weakened muscles for particular functions and responses. If you have neuromuscular dysfunction or a neuromuscular disorder (such as muscular dystrophy), muscles throughout the body may weaken progressively e-stim can help to slow this progression and improve motor control.Į-stim can also be used by athletes as a muscle conditioning or recovery tool.If you have a shoulder injury (e.g., a rotator cuff tear or impingement), resting, immobilizing, or favoring the shoulder may cause the muscles in and around that shoulder to weaken.If you’ve torn an Achilles tendon, the muscles in your calf and foot may become atrophied from wearing a boot to immobilize the ankle, or from changing your gait to favor the injured ankle.This process strengthens and repairs tissue, particularly muscles which have become shortened, weakened, or atrophied due to injury or disease. The primary purpose of e-stim therapy is to simulate what happens in the body when you voluntarily contract and release a muscle many times in a row.
An e-stim device has various settings, meaning the contractions may be barely noticeable or they may feel, and look, like involuntary muscle twitches. This machine generates electric impulses that stimulate your skeletal muscles to contract. He or she then turns a dial or presses a button on an electrical muscle stimulation device, a console that’s either plugged into the wall or battery-operated. Another form of e-stim therapy called TENS ( transcutaneous electrical nerve stimulation) works on nerves rather than muscles.ĭuring e-stim treatment, a therapist secures electrode pads to your skin. If you’ve ever visited a physical therapist to rehabilitate a soft tissue injury, it’s possible you’ve experienced a form of electrical muscle stimulation, or e-stim therapy (also referred to as EMS, electromyostimulation or neuromuscular electrical stimulation, and NMES).
