Electrical muscle stimulation (EMS), also known as neuromuscular electrical stimulation (NMES), is a type of physical therapy that uses electrical impulses to stimulate the contraction of muscles.
This technique is commonly used to help individuals recover from injuries, improve muscle strength, and reduce muscle pain and soreness. EMS machines are widely available and can be used in physical therapy clinics, gyms, and even at home.
How Does EMS Work?
The electrical impulses delivered by an EMS machine mimic the electrical signals that the body naturally produces to initiate muscle contractions. When these impulses are delivered to the muscles through the electrodes, they cause the muscles to contract.
There are different types of EMS machines available, each with their own unique features and settings. Some machines are designed for home use, while others are used in physical therapy clinics or fitness centers.
It’s important to note that not all the machines are the same, and you should consult with a physical therapist or doctor before starting treatment.

The Benefits of EMS
One of the main benefits of EMS is improved muscle strength and endurance. When the muscles are stimulated by the electrical impulses, they contract and relax in a manner similar to resistance training. This can lead to an increase in muscle size and strength over time.
Another benefit of EMS is reduced muscle soreness and pain. The electrical impulses can increase blood flow to the muscles, which can help to reduce inflammation and promote healing.
Additionally, the use of EMS can improve range of motion and flexibility, as well as enhance recovery after intense exercise.
Looking at the current studies the folks over at Legion Athletics concluded that EMS may aid in muscle hypertrophy (growth) when combined with resistance training.
In some cases, EMS can also be used to help with weight loss when combined with regular physical activity and proper nutrition.
The Risks of EMS
There are some contraindications for certain medical conditions, such as heart problems, deep vein thrombosis, and pregnancy. Always consult with a physical therapist or doctor before starting treatment.
Some of the side effects of EMS include skin irritation at the site of the electrodes, as well as muscle soreness.
Long-term side effects of using an EMS machine have not been extensively studied, and more research is needed to fully understand the potential risks. It is recommended to use the machine under the guidance of a professional, as well as to follow the manufacturer’s instructions for use.
How EMS can aid in muscle growth and hypertrophy?
EMS works by sending electrical impulses to the muscles, causing them to contract and relax. This contraction is similar to what occurs during traditional weightlifting and resistance training. By contracting the muscle repeatedly, it can lead to muscle growth, also known as hypertrophy.
The electrical impulses from the EMS machine can be adjusted to different intensities, which can target specific muscle fibers and provide a more intense workout. This can lead to an increase in muscle strength, tone, and size.
Additionally, EMS can also aid in muscle recovery. By contracting the muscles, it increases blood flow and oxygenation to the area, which can help to reduce muscle soreness and speed up the recovery process.
One should note, that while EMS can aid in muscle growth and recovery, it should not be considered a replacement for traditional weightlifting and resistance training. A well-rounded exercise regimen, including a combination of cardio, strength training and stretching is optimal for muscle growth and overall fitness.

Can electrical muscle stimulation help me lose weight?
While EMS may aid in muscle growth, it is not a substitute for regular physical activity and proper nutrition. To lose weight, it is imperative to maintain a calorie deficit through a combination of diet and exercise.
One study has shown that combining resistance training with EMS may aid in weight loss”
“So, bodyweight training with EMS can significantly reduce body fat percentage, and waist circumference.”
Journal of Critical Reviews
Emphasis should be placed on the weight training portion with EMS facilitating the process.
Safety considerations for using EMS on your face and neck
Extreme caution should be taken when using EMS on the face or neck because these areas are particularly sensitive and have a high density of nerves and blood vessels.
Using electrical stimulation on the face and neck can increase the risk of nerve damage and injury. The electrical impulses can potentially affect the nerves that control facial expressions and movement. Additionally, the skin on the face and neck is thinner and more delicate than on other parts of the body, making it more susceptible to irritation and injury.
Another reason to be cautious when using EMS on the face and neck is because these areas are close to the eyes and brain. It’s possible that the electrical impulses could be transmitted to the eyes, which may cause eye damage.
How long does electrical stimulation last?
The duration of an EMS session can vary depending on the specific machine and the individual’s fitness goals. Typically, a session lasts between 20-30 minutes, with the electrical impulses being applied to the targeted muscle group for several seconds at a time, followed by a rest period.
Keep in mind that a single session of EMS may be temporary. The lasting effects of EMS on muscle growth and recovery can be seen with consistent use over time.
What’s the recommended electrical frequency for pain reduction?
The recommended electrical frequency for pain reduction can vary depending on the condition being treated and the individual’s sensitivity to electrical stimulation. Generally, low frequency electrical stimulation (1-10 Hz) is typically used for pain management and muscle relaxation. Meanwhile, high frequency electrical stimulation (50-100 Hz) is used for muscle contraction and muscle strengthening.
For pain reduction specifically, it is recommended to use low frequency, high intensity stimulation. This means using a low frequency (around 2-4 Hz) and a high intensity (around 50-70mA) to target the affected area.
Final Word
Electrical Muscle Stimulation (EMS) is a powerful tool that can aid in muscle growth, recovery, and pain reduction. However, it’s crucial to understand how to use it safely and effectively in order to achieve optimal results.
One of the key takeaways is that the duration, frequency and intensity of the electrical stimulation should be tailored to the individual’s fitness goals and current physical condition. It’s also crucial to monitor progress and adjust usage accordingly, to avoid overuse and potential for muscle damage.
Low frequency, high intensity stimulation are excellent for pain reduction. That said, it is important to seek guidance from a physical therapist or other medical professional before using e-stim.
Finally, take note that EMS should not be seen as a replacement for regular exercise and physical therapy. Instead see it as a complementary tool to enhance the results of these activities. Maintaining a consistent exercise regimen and working with a physical therapist can provide long-term benefits for muscle growth and recovery.
