Neuromuscular Electrical Stimulation (NMES) is a type of electrical muscle stimulation therapy that uses electric currents to stimulate muscle contractions and relieve pain. NMES typically involves placing electrodes on the skin over the muscle belly or at the proximal and distal ends of the muscle. The size of the electrodes depends on the size of the muscle being stimulated. During NMES therapy, the first muscle fibres to be recruited are the large-diameter fast-twitch type 2 muscle fibres, which produce the strongest and quickest contractions. This form of therapy has been used to treat chronic neck pain, which affects 10-24% of the general population, and has been found to be successful in pain management for many people.

What You'll Learn
Bipolar electrode placement
Neuromuscular Electrical Stimulation (NMES) is a type of pain relief therapy that uses a mild electrical current to treat pain. It involves placing electrodes on the skin to stimulate muscle contractions. The first muscle fibres to be recruited during NMES are the large-diameter fast-twitch type 2 muscle fibres, which produce the strongest and quickest contractions.
Before beginning NMES with bipolar electrode placement, the patient should be seated comfortably to allow for muscle relaxation, which is necessary for easier muscle stimulation. The skin should be inspected for any abrasions or injuries, and then properly cleaned with a cloth and water or alcohol-based wipes. It is important to ensure that the skin is completely dry before applying the electrodes.

Muscle relaxation
Electrical Muscle Stimulation (EMS), also known as neuromuscular electrical stimulation (NMES), is a technique used in physical therapy to induce muscle contractions using electric impulses. NMES is often used to aid in muscle relaxation, which is an important aspect of pain management and stress relief.
One muscle relaxation technique used in NMES is progressive muscle relaxation (PMR), also known as Jacobson's relaxation technique. PMR involves tensing specific muscle groups for about 5 seconds and then relaxing them for 10 to 20 seconds, focusing on the difference between the tension and relaxation. This technique helps individuals recognize and become familiar with the sensations of tension and relaxation in their muscles.
Benefits of PMR
PMR has several benefits, including anxiety relief and improved sleep. It can also help manage the physical effects of stress, such as muscle tightness and tension. Additionally, PMR can be easily practiced at home without any special equipment, requiring only focus, attention, and a quiet environment.
Precautions
It is important to consult a doctor before performing NMES or PMR if individuals have any medical issues or concerns, such as pulled muscles or broken bones. During NMES treatment, the patient should be comfortably seated to facilitate muscle relaxation, and the skin should be inspected and cleaned before electrode application.

Skin preparation
Electrical stimulation therapy, such as Transcutaneous Electrical Nerve Stimulation (TENS) and Neuromuscular Electrical Stimulation (NMES), is a non-invasive method of pain relief that uses a mild electrical current to activate peripheral nerves.
Inspect the Skin
Before beginning electrical stimulation therapy, it is important to thoroughly inspect the skin where the electrodes will be placed. Check for any skin abrasions, injuries, openings, or irritations. This inspection is essential to ensure that the skin is intact and healthy, reducing the risk of discomfort or further complications.
Clean the Skin
After inspection, the skin should be properly cleaned to remove any substances that might interfere with the therapy or cause skin irritation. Use a clean cloth, wet towel, or alcohol-based wipes to gently clean the area. Remove any lotions, oils, makeup, or dead skin from the surface. Ensure that the skin is thoroughly dried before proceeding to the next step.
Consider Hair Removal
If the skin in the target area is very hairy, consider removing the hair to ensure better contact between the electrodes and the skin. Shaving is an option, but it is recommended to do this a day before the stimulation session to avoid irritation during the procedure. Alternatively, you can use scissors to carefully clip the hair as close to the skin as possible without abrading the skin.
Avoid Irritants
When applying electrical stimulation therapy, it is important to avoid the use of irritant substances in the treated areas. This includes substances like SLS, as electrical stimulation can escalate skin reactions to low concentrations of irritants. Additionally, be cautious when using adhesives, gels, or materials containing potential allergens like acrylic acid, propylene glycol, rubber, or nickel, as they may cause skin irritation or allergic reactions.
Ensure Comfort and Relaxation
Before initiating muscle stimulation, ensure that the patient is comfortably seated or positioned, allowing their muscles to relax. This relaxation facilitates easier and more effective muscle stimulation during the therapy.

Pulse duration
Neuromuscular Electrical Stimulation (NMES) is a modality that sends electrical impulses to nerves, causing muscles to contract by mimicking the action potential coming from the central nervous system. It is used to strengthen and maintain muscle strength and prevent atrophy, especially in immobilized patients.
The pulse duration can be adjusted to achieve the desired muscle contraction within comfortable tolerable levels for the patient. Balancing the amplitude and the pulse width can help optimize both the muscle contraction produced and the comfort for the patient. For example, a wider pulse duration may allow for a lower amplitude, increasing patient comfort.
The pulse duration can be adjusted based on the size of the muscle being stimulated. For small muscles, the pulse duration is approximately 150-200 microseconds, and for large muscles, it is 200-300 microseconds.
Longer pulse durations result in greater evoked and normalized torque compared to shorter pulse durations. For instance, a pulse duration of 450 microseconds has been shown to be effective in conducting electrically induced resistance training in individuals with spinal cord injuries. However, most researchers have used pulse durations of 300 microseconds or below in their studies, which may limit the outcome of NMES protocols in maximizing torque output.

Capacitive reactance
Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive method of pain relief that uses a mild electrical current to activate peripheral nerves and stimulate the pain gate mechanism and/or the opioid system.
In the context of TENS therapy, which involves high-frequency signals between 2 to 200 Hz, a type of resistance called capacitive reactance becomes important. This refers to the opposition that a capacitor offers to the flow of alternating current in an electric circuit. In other words, it is the resistance offered by the capacitance of the tissue to the flow of alternating current.
The electric current from TENS therapy is believed to help release pain-reducing chemicals produced by the body. This form of therapy has been found to be effective for many people, although researchers are still working to understand why it works better for some than others.
Capacitive technologies have been highlighted for their potential in highly controlled and personalized electrical stimulation. These technologies can be used in implantable biomedical systems for both research and clinical practice, emphasizing their versatility in a wide range of customized therapies. Further understanding of the electric field behavior and the interplay between stimuli parameters and osteoconductive responses is necessary for the development of these personalized E-Stim therapies.

Frequently asked questions
NMES stands for Neuromuscular Electrical Stimulation. It is a type of electrical stimulation therapy that uses muscle contractions to stimulate nerves and provide pain relief.
NMES involves placing electrodes on the skin over the muscle or muscle group to be stimulated. The size and placement of the electrodes depend on the size and location of the muscle(s) being targeted.
NMES is a non-invasive method of pain relief that does not require the use of drugs. It is also relatively inexpensive compared to long-term drug therapy.
NMES is generally considered safe, but it is important to ensure that the skin is properly cleaned and inspected for any injuries or abrasions before applying the electrodes. NMES may not be suitable for people with certain medical conditions, such as epilepsy or a pacemaker.
NMES therapy is often administered by physical therapists or other healthcare providers. You can also purchase NMES devices online or in pharmacies and use them at home.
