NMES is routinely used by physical and occupational therapists to help restore muscle function. The VitalStim® Therapy device was specifically developed in 2002 for the small muscles on the throat used for swallowing. The FDA has mandated that only clinicians that are VitalStim certified may use this treatment for swallowing therapy.
Is NMES a stand-alone treatment?
However, NMES is not intended as a stand-alone treatment. Patients receiving NMES should, in addition, undertake a comprehensive therapeutic exercise programme (supervised or at home). When patients are unable to perform voluntary contractions—for example, sedated patients in the ICU—NMES is applied alone. Denervated muscles
What is NMES and how does it work?
NMES has also been shown to improve muscle strength when applied with the patient in sitting or static standing to move the ankle through ROM in a cyclical manner without patient involvement. We recommend using NMES while patients are walking because it has been associated with a therapeutic benefit that persists after the NMES treatment ends.69
How is NMES used in physical therapy?
In all the conditions included in this review, NMES has been used to activate, strengthen, or retrain muscles to improve outcomes or hasten the achievement of treatment goals. Throughout this article, we provide details and analysis of clinical studies in which NMES was used in a manner that is relevant to PT practice.
What are the risks associated with NMES treatment?
The most common risks associated with NMES treatment are (1) electrical surge or shock should the equipment malfunction; (2) skin irritation or allergy at the electrode sites; (3) pain during treatment if the current amplitude is not adjusted slowly and on the basis of patient feedback; and (4) post-treatment muscle soreness.
When should NMES be used?
Neuromuscular electrical stimulation (NMES) of paralyzed muscles can be used to restore or replace motor function in individuals who have upper motor neuron damage from causes such as stroke or spinal cord injury (SCI).
Why would you use NMES?
Who Can Benefit? General NMES: Children who need to gain strength or range in a certain muscle group may benefit from this service (e.g. post-surgery or general muscle weakness). Neuropresthetics: Children who may benefit from the use of these devices include those with foot drop while walking or difficulty grasping.
When should I use muscle stimulation?
Retraining muscles after surgery or illness. Occasionally, following orthopedic surgery or illness (such as a stroke), a patient may have difficulty contracting muscles at will. In such cases, e-stim can be used for “muscle re-education.” The electrical impulses contract the muscle involuntarily.

When do you use TENS vs NMES?
As another example, TENS units are typically used for pain relief, while NMES units are used to retrain muscles after an injury, even though both TENS and NMES use similar stimulation waveforms.
What is the difference between NMES and EMS?
You are then able to track your individual pain score per body part over time. NMES on the other hand (often referred to as EMS) stands for NeuroMuscular Electrical Stimulation, and uses electrical signals at higher Hz rates to stimulate muscle fibers.
Do you use EMS before or after workout?
Pre-Workout Before you get your sweat on, electrical muscle stimulation therapy can jumpstart blood circulation. This helps increase blood and oxygen transport to the muscle, preparing it for activity just as a dynamic warm-up would.
What are the contraindications for electrical stimulation?
These are just things to consider before you make a determination if the treatment is appropriate.Electrical Devices. The first red flag is use of a cardiac pacemaker or implanted electrical device. ... Malignant Tissue/Metastases. ... Impaired/Absent Sensation. ... Epilepsy/Pregnancy. ... Thrombosis/Hemorrage. ... Cognition.
How often should you use a muscle stimulator?
You can begin with one 15-minute therapy session. Repeat for another 15 minutes if needed. Use up to three times per day at a maximum. During each therapy, rate your pain before and after the session, 1 (low) to 10 (high) in order to gauge the true reduction of pain.
Where do you place the NMES electrode?
For optimal results, when applying NMES treatment to your patients, take the time to identify the best placement for the electrodes. Ideally the electrodes are placed on the motor point of the targeted muscle.
What is NMES in speech therapy?
Neuromuscular Electrical Stimulation NMES is done using a VitalStim® or Ampcare™ device and is a non-invasive therapy that can improve swallowing. Through electrical stimulation, this therapy aids in muscle strengthening and helps your muscles relearn the process of swallowing.
What are the parameters for NMES?

What is NMES therapy?
Neuromuscular electrical stimulation (NMES) is a specialized form of electrical stimulation therapy designed to treat dysphagia. This special therapy has been cleared by the Food and Drug Administration and is non-invasive (does not go inside the body).
What is the purpose of NMES?
During NMES, a special device is used to deliver a small electric current to a child’s face or neck. The electrical current is delivered through specially placed electrodes on the child’s face and/or neck. The electrical current stimulates the nerves and muscles responsible for swallowing.
What is neuromuscular electrical stimulation?
Neuromuscular electrical stimulation benefits. 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.
How long does a feeding therapy session last?
Each session lasts about 45 to 60 minutes and consists of a combination of feeding and oral motor therapies and exercises. In a typical treatment session, stimulation remains on for the duration of the session or as the patient tolerates the stimulation.
Why do children need electrical stimulation?
The main goal of electrical stimulation therapy is to strengthen weak muscles and to help children gain control of their oral motor skills.
Why is NMES used in quad sets?
Typically, NMES is utilized while performing quad sets in order to improve contraction and activation. This study , however, looks at NMES superimposed on a sit-to-stand-to-sit ...
How much Hz is used for NMES?
For the NMES group, treatment was applied at 35 and 50 Hz (alternating days) to address both slow and fast-twitch fibers with intensity (max intensity: 120 mA) increasing as patient tolerated at each repetition of each session.
What frequency is needed for NMES?
In some cases, it may be more useful to apply a different frequency, pulse width, or amplitude. A lower frequency of 1 to 10 Hz, for example, might work better when a muscle gets exhausted too fast.
Why does a stimulation become painful when an electrode partly comes off?
This is because the electricity is spread over the surface. That’s also why a stimulation can become more painful when an electrode partly comes off. The same amount of electricity has to go through the electrodes, and increased electricity thus goes through every stimulated piece of skin.
What is the amplitude of a neuromuscular stimulation?
The Amplitude. In neuromuscular electrical stimulation, the Amplitude represents the electric current of the stimulation. This is measured in Milli Ampere (mA). The amplitude determines how deep the stimulation will go and therefore how many motoneurons are stimulated, and thus how strong the muscle tension will become.
What is the importance of electrodes in tens?
Position of the electrodes. In TENS, the precise position of the electrodes is of great importance, especially in the smaller muscles. When the muscle belly is not or not entirely stimulated, a greater intensity is needed in order to reach the same effect, if this effect can even still be reached.
What are the principles of electrical stimulation?
However, every stimulation works with the following principles: frequency, amplitude, and pulse width. If you’re first wondering what electrical stimulation actually is and why it’s great, hit the link. Furtherly, if you’re thinking of applying electrical stimulation, always follow the instructions in the manual that belongs to your stimulator.
What frequency is used for smooth muscle tension?
The frequency that is used for smooth muscles tensions is usually about 20 to 50 Hz. A frequency that is too low makes a movement jerky and a frequency that’s too high makes the stimulation painful.
Why is it important to use bigger electrodes?
On the one hand, a big part of the muscle can be stimulated, involving as much muscle fibres as possible in the stimulation. Furthermore, the applied electricity can be spread better in a bigger electrode.
