Electrical muscle stimulation (EMS) is a treatment that involves applying electrodes to the skin near an affected muscle to send an electrical current to the area. This current causes rhythmic muscle contractions. While EMS is generally considered safe, there have been reports of shocks, burns, bruising, skin irritation, and pain associated with the use of unregulated devices. FDA-cleared EMS devices are intended for use in physical therapy and rehabilitation under the supervision of a healthcare professional. It is important to discuss the risks and benefits of EMS with a healthcare provider before starting treatment, especially for individuals with certain health conditions or implanted devices.

What You'll Learn
FDA-approved vs. unapproved devices
Electronic muscle stimulators (EMS devices) are considered devices under the Federal Food, Drug, and Cosmetic Act. The FDA is responsible for regulating the sale of all electrical muscle stimulators in the United States. Firms that market EMS devices are required to comply with FDA premarket regulatory requirements before they can legally sell their devices.
The FDA has cleared many electrical muscle stimulators for prescription use in treating medical conditions. Doctors may use electrical muscle stimulators for patients who require muscle re-education, relaxation of muscle spasms, increased range of motion, and prevention of muscle atrophy. Most electrical muscle stimulators that have been reviewed by the FDA are intended for use in physical therapy and rehabilitation under the direction of a healthcare professional.
To achieve FDA clearance, manufacturers must demonstrate that their device is substantially equivalent to existing devices with established safety and efficacy profiles. This involves submitting a 510(k) application, which outlines the device's intended use, technological characteristics, and performance data. The FDA reviews this information to ensure that the new device is as safe and effective as similar devices already on the market.
Using a product that has not met FDA requirements is not necessarily unsafe, but it could be. The FDA has received reports of shocks, burns, bruising, skin irritation, pain, and interference with other critical medical devices associated with the use of unregulated products. Unregulated devices may also have safety issues with cables and leads that can lead to accidental shocks and electrocution.
It is important to note that while EMS devices may be able to temporarily strengthen, tone, or firm muscles, no EMS devices have been cleared by the FDA for weight loss, girth reduction, or obtaining "rock-hard" abs.

Burns from electrodes
Transcutaneous electrical nerve stimulation (TENS) is a type of pain relief therapy that uses a low-voltage electrical current to block pain or change one's perception of it. TENS devices are battery-powered and use electrodes to deliver electrical impulses through the surface of the skin. While TENS is generally safe, burns from the electrodes have been reported, albeit rarely.
The FDA has cleared many electrical muscle stimulators (EMS devices) for prescription use in treating medical conditions. Doctors may use EMS devices for patients who require muscle re-education, relaxation of muscle spasms, increased range of motion, and the prevention of muscle atrophy. The FDA has received reports of shocks, burns, bruising, skin irritation, and pain associated with the use of some unregulated EMS devices.
Functional electrical stimulation (FES) is a treatment that sends electrical impulses to muscles and nerves to make them move. FES is a treatment option for foot drop, weakness caused by damage to the brain or spinal cord, or conditions that cause muscle dysfunction. While FES offers many benefits, it can cause discomfort. The sensation felt during FES can vary depending on the level of intensity, ranging from a tingling sensation to a burning sensation.
An electrical burn occurs when a person comes into contact with electricity. The severity of an electrical burn can range from first-degree to third-degree, with third-degree burns impacting the innermost layer of skin. Electrical burns can also cause internal damage to organs, which may be severe or even cause death. The entrance and exit areas of electrical burn on the skin are often painless and superficial, but the potential for internal injury means that electrical shocks should not be underestimated.

Potential adverse effects
Electronic muscle stimulators (EMS) are devices that use electrical impulses to stimulate muscles and nerves. While generally considered safe, there are some potential adverse effects associated with their use.
One potential adverse effect of using EMS devices is skin irritation and burns. The FDA has received reports of burns and skin irritation associated with the use of unregulated EMS devices. It is important to use FDA-cleared devices and follow the instructions carefully to minimize the risk of skin irritation and burns.
Another potential adverse effect is discomfort or pain. While EMS devices are intended to be painless, they can cause mild discomfort, especially at higher intensity settings. The sensation can range from a tingling sensation to a burning sensation, depending on the level of intensity. It is important to adjust the settings to a comfortable level and consult a healthcare provider if you experience any discomfort or pain.
EMS devices can also interfere with other medical devices, such as pacemakers. It is crucial to consult a healthcare professional before using an EMS device if you have any implanted medical devices or underlying health conditions.
Additionally, EMS devices should not be placed too close to transdermal drug patches as this may lead to complications. It is important to carefully review the placement instructions and precautions provided with the device to ensure safe use.
While rare, there is also a risk of accidental shock and electrocution associated with the use of EMS devices, particularly those that are unregulated or improperly used. This risk may extend not only to the user but also to other household members, including children. Therefore, it is imperative to use FDA-cleared devices, follow safety instructions, and keep the devices out of the reach of children.

Safety concerns for certain groups
While electrical muscle stimulation is generally considered safe, certain groups of people should exercise caution when using these devices.
People with heart conditions or implanted electrical devices should avoid using electrical muscle stimulators. This includes individuals with pacemakers or spinal cord stimulators, as the electrical impulses from the stimulators may interfere with these devices.
Pregnant or menstruating individuals should also use caution when considering electrical muscle stimulation. The FDA recommends caution for these groups, as muscle contractions induced by the stimulators may potentially affect the pregnancy or menstruation process.
Additionally, those with bone fractures, burns, skin lesions, lupus erythematosus, thromboembolic disease, or deep vein thrombosis should refrain from using electrical muscle stimulators. The electrical impulses may interfere with healing processes or exacerbate existing conditions.
It is important to consult a healthcare provider before using an electrical muscle stimulator to ensure it is safe and appropriate for your individual needs and health status.

Benefits vs. risks
Electrical muscle stimulation (EMS) is a versatile treatment option that can be used to reduce pain, improve movement, and support healing. It is often used in physical therapy and rehabilitation to address issues such as weak muscles, long-term pain, and nerve injuries. EMS involves sending small electrical signals to nerves and muscles, which can cause rhythmic muscle contractions and improve blood flow. This treatment has been found to be particularly effective in treating certain upper and lower extremity issues post-stroke, as well as muscle weakness in knee osteoarthritis.
While EMS has been shown to have numerous benefits, there are also some risks and considerations to keep in mind. One important consideration is that EMS is not suitable for everyone. People with heart conditions or implanted devices should avoid EMS treatments, as they may interfere with other critically important medical devices such as pacemakers. Additionally, EMS should not be used on vital body parts such as the carotid sinus nerves, across the chest, or across the brain.
Another potential risk is the occurrence of skin irritation and burns. While rare, burns can happen if the electrodes used in EMS treatments are not properly placed or if the intensity of the electrical current is too high. It is important for healthcare providers to monitor the level settings and placement of electrodes to ensure the patient's comfort and safety.
It is also worth noting that the effectiveness of EMS may vary depending on the individual and their specific needs. While some people experience significant pain relief and improved muscle function, others may not see the same results. More research is needed to fully understand the mechanisms behind EMS and its long-term effects.
In conclusion, while EMS has been shown to have numerous benefits, it is important to carefully consider the potential risks and consult with a healthcare professional before undergoing treatment.
