Stimulation

Electrical Muscle Stimulation or E-stim therapy sends signals to targeted muscles to make them contract.

By causing repeated muscle contractions, blood flow improves, helping repair injured muscles.

 

Whether you’re recovering from an injury or stroke or dealing with the pain of fibromyalgia or another condition, you may benefit from a physical therapy procedure called electrical stimulation, or e-stim. E-stim sends mild electrical pulses through the skin to help stimulate injured muscles or manipulate nerves to reduce pain.


E-stim uses electrical pulses to mimic the action of signals coming from neurons (cells in your nervous system). These mild electrical currents target either muscles or nerves. E-stim therapy for muscle recovery sends signals to targeted muscles to make them contract (flexing your biceps is a form of muscle contraction). By causing repeated muscle contractions, blood flow improves, helping repair injured muscles.

Those muscles also improve their strength through repeated cycles of contraction and relaxation. E-stim can also “train” muscles to respond to the body’s natural signals to contract. This is an especially helpful benefit for stroke survivors who must essentially relearn basic motor functions.

The type of e-stim that focuses on pain relief sends signals on a different wavelength so they reach the nerves, rather than the muscles. Electrical stimulation can block pain receptors from being sent from nerves to the brain.

 

What are the main types of e-stim?
 

The two main types of e-stim are transcutaneous electrical nerve stimulation (TENS) and electrical muscle stimulation (EMS).


-TENS may be used for chronic (long-term) pain as well as for acute (short-term) pain. Electrodes are placed on the skin near the source of the pain. Signals are sent through nerve fibers to block or at least reduce the pain signals traveling to the brain.
-EMS uses a slightly stronger current than TENS to get muscles to contract. The unit’s electrodes (also placed on the skin near the affected muscles) cause rhythmic contractions. This can improve muscle strength if the user attempts to contract the muscle simultaneously.

Other e-stim types?


In addition to EMS and TENS, your doctor or physical therapist may recommend other e-stim treatments. One of the following similar e-stim treatments may help you, depending on your condition:

 

-Electrical stimulation for tissue repair (ESTR) helps reduce swelling, increase circulation, and speed up wound healing.
-Interferential current (IFC) stimulates nerves to reduce pain.
-Neuromuscular electrical stimulation (NMES) stimulates the nerves in muscles to restore function and strength, prevent muscle atrophy, and reduce muscle spasms.
-Functional electrical stimulation (FES) involves a unit implanted in the body to provide long-term muscle stimulation aimed at preserving function and motor skills.
-Spinal cord stimulation (SCS) uses an implantable device to relieve pain.
-Iontophoresis helps deliver ionically charged medication to tissue to help speed up healing.
 

You may have seen TV and online advertisements for home e-stim systems. If you’re interested in one of these products, talk with your doctor or a physical therapist. Be sure to get proper instruction on its use before trying it out.


How does e-stim work?


E-stim uses small electrodes placed on the skin. The electrodes are small, sticky pads that should come off with little discomfort at the end of the session. Several electrodes are placed around the area receiving treatment. Wires from the e-stim device are attached to the pads. Steady streams of electrical pulses are delivered through the wires from the e-stim unit. The unit may be small enough to fit in your hand or larger, like a landline phone and answering machine. For muscular stimulation, the pulses will reach the muscles, signaling them to contract. Pulses aimed at the nervous system block the transmission of pain signals from reaching the spinal cord and brain. The pulses also stimulate the body to produce more natural pain-relieving chemicals called endorphins. Depending on the type of e-stim, you may feel a muscle twitch or contract repeatedly. Each e-stim therapy session may last 5 to 15 minutes, depending on the condition being treated.

 

What does it treat?


E-stim may be appropriate for the following conditions:

 

Back pain
Cancer-related pain
Dysphagia (trouble swallowing)
Fibromyalgia
Joint pain
Arthritis
Muscle conditioning (mostly for athletes, such as long-distance runners)
Muscle injury from trauma or disease
Nerve inflammation
Poor muscle strength
Urinary incontinence
Spinal cord injury
Stroke
Surgery recovery

If you’re interested in e-stim as a tool for muscle conditioning or pain relief, talk with your doctor about your options and how to proceed safely.
