The Benefits of Estim (Electrical Muscle Stimulation)

Estim

What is Estim (Electrical Muscle Stimulation)?

Electrical stimulation, also referred to as e-stim, is a tool that applies electrical stimulation to a muscle or muscle group for pain, spasticity and muscle contraction. It is placed on your skin by electrodes that come in different sizes to the specific area you want to treat. The electrodes deliver impulses through the skin to make a muscle contraction, inhibit spasticity, and relieve chronic pain.

Electrical Muscle Stimulation (EMS) is a method of non-invasive muscle stimulation that has been used for years and is now being adopted by athletes and frequent travelers because it helps reduce muscle fatigue and soreness and increase the rate of recovery. It also reduces stress on muscles while increasing the range of motion due to decreased stiffness in the joints. The EMS technique can be applied to any part of the body, with or without skin contact.

What can Estim help with?

Electrical stimulation can help build and regain strength in muscles suffering from atrophy. It is also used to inhibit spastic muscles to help gain a specific range of motion that someone may be lacking in. It is most commonly used for spasms in the back which help relieve pain by sending currents from the electrodes into, and through, the skin directly to the spasm itself.

Does Electrical Muscle Stimulation cause pain?

E-stim can be an unusual feeling, but is not a painful therapy. Many who experience low sensation actually enjoy the opportunity to be able to feel their muscles (sometimes for the very first time!). As you would hear our occupational therapists say, sensory drives motor function. If you can’t feel the muscles, you can’t use them, which is why e-stim is a wonderful therapeutic tool.

How Estim therapy works

Electrical stimulation is used in a few ways to achieve different effects, such as muscle strengthening and relaxation. EMS uses short bursts of high-energy, low voltage electric currents that stimulate the muscles.

When the electricity is applied to a specific site through electrodes, it interrupts the pain signal transmitting the sensation of pain from the brain to that area. In addition, the electrical energy damages some cells at the application site and stimulates nerves that then transmit more positive signals to other parts of your body. As a result, you will feel less pain and more relief.

Estim can target specific muscle groups. The current stimulates the muscles, causing them to contract over time. With continued application, these contractions will cause strengthening of the targeted area and help it relax by increasing blood flow and circulation in both directions. This helps improve flexibility as well. EMS therapy is also known for reducing inflammation and resulting swelling.

Estim has been used for years in physical therapy offices, chiropractic clinics, and some hospitals to increase mobility and maintain strength without overworking a patient’s body part or joint. In addition, it can be taken home by the patient to use when they want and how often they feel necessary.

Benefits of Electrical Muscle Stimulation are:

  • reduces pain
  • restores movement
  • speeds up the healing process
  • improves circulation
  • aids in sleep

Side effects include dizziness and headaches, and estim is not for people with diabetes or heart conditions. 

What are the different types of Estim?

At CWJR, we currently utilize Neuromuscular Electrical Stimulation, or NMES, and Transcutaneous Electrical Nerve Stimulator, or TENS, units. According to the Pennsylvania Physical Therapy Association, an associate of the American Physical Therapy Association, NMES “…involves the use of devices that transmit electrical impulses through electrodes to stimulate muscle groups. There are two different types of NMES: one is functional electrical stimulation (FES) and the second is lateral electrical surface stimulation (LESS).”

We utilize FES a great deal at our facility, as it works to replace stimuli from destroyed nerve pathways through electrical stimulation. One of the machines we utilize FES on is our RT600™, as this form of e-stim works to improve muscle tone, strength, and the ability to increase independence – especially with walking. We also utilize NMES with our VitalStim® unit, helping those with oral motor weakness and feeding difficulties.

Additionally, we utilize TENS units, which apply electrical stimulation directly to the pain site. TENS are commonly used to relieve pain from surgery, symptoms caused by a traumatic brain injury, chronic pain, muscular pain, etc. One of the great benefits of a TENS unit, is that you can use these in an inpatient, outpatient and even a home setting.

Who should use Estim Therapies?

Anyone can use estim therapy, with it being a non-invasive method of treatment. Estim is also known for reducing inflammation and resulting swelling. In addition, it’s safe to reduce chronic pain because estim will not damage the nerves through overexertion like other methods such as surgery do.

Estim can be taken home by the patient and used on all parts of the body, even when there is no skin contact. The process can be applied virtually anywhere on the body, including the neck, shoulders, legs, and lower back. Electrical Muscle Stimulation targets specific muscle groups with brief, high-energy pulses of low voltage electric currents that stimulate the muscles

Estim stimulates nerve receptors in the muscles and interrupts pain signals sent from the brain to the body. Estim is also known for increasing range of motion due to decreased stiffness in joints and can help reduce tightness, soreness, and fatigue.

Estim is easy to use, portable, and very inexpensive.

How can e-stim be used at home?

As you may or may not already know, various forms of e-stim can certainly be used at home. Most commonly you will see people with their own TENS units, especially if they deal with chronic and deep muscular pain. E-stim units, like smaller four-electrode FES systems, can also be purchased for in-home use by themselves, or in accompaniment with other devices such as a WalkAide.

If your therapist believes an e-stim unit would be beneficial for in-home use, they will incorporate this into your personalized home exercise program, or HEP. Please speak with your therapist if you would like to learn more about the varying forms of electrical stimulation, and how they can benefit your everyday life.

Conclusion

If you’re an athlete, a frequent traveler, or just looking to stay in shape without going through the pain and stiffness of exercise, then Electrical Muscle Stimulation might be your answer. In this post, we talked about what it is precisely and how you can use it to reduce muscle soreness and fatigue while increasing the range of motion for joints.
