Neuromuscular and Muscular Electrical Stimulation (NMES) has emerged as a promising technology for maintaining muscle mass and function in space. Originally designed for medical rehabilitation purposes, the technology has also been implemented for space missions, including on the International Space Station (ISS). Keep reading to find out more about this technology and how itβs evolved, as well as why itβs beneficial to astronauts.
What is NMES?
NMES is a technique that uses electrical impulses to stimulate muscles. These impulses are delivered via electrodes placed on the skin and target the motor neurons, which are the cells responsible for transmitting signals from the brain to the muscles. When the motor neurons are stimulated by the electrical impulses, they trigger the muscles to contract and relax, producing a range of therapeutic effects.
NMES can be used for a variety of rehabilitation purposes, such as improving muscle function and strength after injury or surgery, or for treating conditions like muscular dystrophy or multiple sclerosis. It can also be used for more general fitness and performance enhancement, such as improving muscle tone or preventing muscle atrophy. The technique is based on principles of neurophysiology and can be applied to a range of different muscle groups depending on the specific goals of the treatment.
NMES vs EMS
While NMES and Electrical Muscle Stimulation (EMS) are both types of muscle contraction stimulation that involve electrical impulses, there are some key differences between the two:
Firstly, NMES is typically used to stimulate specific muscles or muscle groups for therapeutic or rehabilitation purposes, while EMS is often used for general muscle stimulation or aesthetic purposes such as muscle toning.
The intensity of the stimulation varies too. NMES often uses a lower frequency of electrical stimulation than EMS, as the goal is to activate specific muscles without causing excessive fatigue. EMS, on the other hand, typically uses a higher frequency of stimulation to induce muscle contractions that lead to muscle toning and development.
The equipment is different as well. EMS devices can range from handheld to more advanced equipment used in clinical settings. Whereas, NMES is usually more advanced and precise, with specialised electrodes and software designed for specific therapeutic purposes.
The one similarity, however, is that it is important to use each technique appropriately and under the guidance of a healthcare professional or qualified practitioner.

The technique can offer numerous benefits for individuals who are recovering from injury or surgery, as well as those who are looking to enhance their athletic performance or improve their muscle tone. Here are some of the benefits of NMES:
- Muscle Strength and Function: Especially in individuals who are recovering from injuries or have weakened muscles due to neurological conditions
- Increased Muscle Mass: Overall helping to improve overall physical performance
- Improved Muscle Endurance: Helps to increase the number of muscle fibres that are recruited during exercise
- Pain Management: A non-pharmacological method for pain management, particularly for musculoskeletal pain and postoperative pain
- Reduced Muscle Atrophy: Helps to combat the loss of muscle mass that can occur due to injury, surgery, or immobilisation
- Improved Circulation: Improves blood flow to the muscles, which can aid in the delivery of oxygen and nutrients to the tissues.
- Increased Range of Motion: Enhances joint flexibility and range of motion, which can be beneficial for individuals recovering from injury or surgery.
Overall, NMES can be a valuable tool in the management of various conditions and for individuals looking to improve their physical performance. However, it is important to consult with a healthcare professional to ensure the safe and effective use of the technique.
For Rehabilitation
As we have previously mentioned, NMES can be a useful technique in rehabilitation as it helps to improve muscle strength, endurance, and function. In addition to the benefits mentioned above, NMES also helps with muscle activation. Due to an injury, surgery or neurological condition, this treatment helps to activate weak or inhibited muscles and prevent muscle atrophy. It will additionally help to build up these muscles improving their function and strength. Read our latest success story of how VIPβs Isogei device helped improve muscle strength by 26%.
For people recovering from an injury or surgery that addicts their motor function, NMES can aid their improvement of this neuromuscular control. Similarly, it provides the added benefit of proprioception, which is the sense of the position and movement of the body. This can be beneficial for individuals recovering from an impediment that affected their balance or coordination.
Does Electrical Stimulation Build Muscle?
Yes, electrical stimulation procedures such as NMES can help to build muscle as it replicates the muscle contractions experienced during exercise.
Research has shown that NMES can help to increase muscle size and strength, particularly in individuals who are unable to perform voluntary exercise due to injury, illness, or surgery. The electrical impulses can also help to activate the deeper muscle fibres, which may be difficult to target with traditional exercises.
NMES could be a feasible and safe alternative to voluntary exercise for people unable to perform high-intensity exercise and the most at-risk older adults. However, it is important to note that not everyone should use NMES to replace voluntary exercise. Rather, it can be a useful adjunct to traditional exercise programs to help build muscle and improve overall physical performance. It is also important to use NMES under a healthcare professional's guidance to ensure the safe and effective use of the technique.
NMES in Space
During spaceflights, astronauts are exposed to microgravity, which can lead to a loss of muscle mass and bone density, as well as changes in muscle fibre composition and neuromuscular function. These changes can increase the risk of injury, and therefore, impair an astronaut's ability to perform tasks during space missions. NEMS involves the application of electrical impulses to muscles to induce muscle contractions, as it is effective in counteracting the effects of microgravity on the musculoskeletal system.
The Benefits for Astronauts
One of the primary effects of microgravity on the musculoskeletal system is muscle atrophy or loss of muscle mass and strength. This occurs as the muscles are no longer required to work against gravity, and therefore do not need to generate as much force. Over time, it can lead to a significant loss of muscle mass and strength, particularly in the lower body. Microgravity can also affect the structure and density of bone tissue. The lack of gravity-induced stress on the bones can cause them to become less dense and weaker, which can increase the risk of fractures and other bone injuries. These changes can be particularly pronounced in the bones of the lower body, which are more exposed to the effects of microgravity.
In the context of spaceflights, NMES has emerged as a potential solution to the problem of muscle atrophy, as it provides a form of exercise that can maintain or even increase muscle strength and mass, as well as improve neuromuscular function. This also can reduce the risk of injuries and improve performance during space flights and after return to Earth.
Beyond its application in space, the NEMS has also been adapted for use in other fields, including the beauty industry. The technology's ability to stimulate muscle contractions has been found to be highly effective in toning and strengthening muscles, leading to increased firmness and improved appearance.
