Electrotherapy is unique; the use of this cutting-edge technology through TENS and NMES devices has been extremely beneficial for a variety of purposes. NMES and TENS science has become widely popular, with many people searching online for relevant information on how and when to use them. The distinction between the two is crucial for understanding exactly what works best for you as we recently analyzed in a previous article.

In fact, this article prompted so many questions from our readers we knew we had to devote some serious space to address them for you. In today’s article, we have gathered some of the most frequently asked questions about NMES and TENS technology, answered by the diPulse experts' team in a science-focused, concise manner. Thank us later.

Once more, what is NMES (Neuromuscular Electrical Stimulation)?

NMES is the activation of muscle contractions using electrical impulses that mimic the messages coming from the central nervous system to the nerve receptors. Those impulses enable the muscle to involuntarily contract as with a regular movement. NMES is frequently used in the recovery and training of muscles through specifically designed programs that vary between different levels of muscle activation. You can also visit our recent blog post for more detailed information about NMES muscle stimulation: What is neuromuscular electrical stimulation?

In short, what’s the difference between TENS and NMES?

TENS and NMES work in the same way but stimulate different neurological elements to achieve results. They are both a form of e-stim but don’t operate in the same way. More specifically, a TENS unit is used to stimulate the sensory nerves at a superficial level to override pain signals on their way to the brain, thereby reducing or eliminating pain sensations. NMES targets muscles through motor nerves, rather than pain signals, making muscles contract directly without our conscious effort. This is why NMES technology is widely used for building muscle and supporting recovery by fitness coaches and top-performing athletes around the world.

Are they both safe to use?

Both TENS and NMES devices are generally considered safe to use as part of a monitored rehabilitation or recovery program. It is advisable to use only certified and reputable quality products so do your research before choosing on one. In some cases, for instance, people suffering from a heart condition or those wearing a pacemaker, it’s important to seek the advice of a healthcare provider before using TENS or NMES. It's advisable to read the instruction manuals before you use any of these devices.

Can you use TENS for NMES?

No. TENS targets sensory nerves and NMES targets motor nerves, so they are used for different purposes. TENS is essentially used for pain relief and NMES is normally used for muscle activation.

I am confused. Should I choose a TENS or an NMES unit?

Knowing your individual needs, lifestyle, and unique objectives, will help you decide which device to choose. As we previously mentioned, TENS technology is designed to interrupt the pain signals sent from your body to your brain. Therefore if you’re suffering from lower back pain, for example, a TENS device would likely be best. If you are a high-performing crossfitter aiming to build muscle and take your athletic performance to the maximum then a diPulse NMES unit is ideal. Similarly, if you are recovering from overtraining and need to supplement your recovery or long for a great massage, there is a diPulse product and program for you.

I am a fitness lover looking to buy an NMES unit. How do I choose from those available online?

We are happy you are discovering the great potential of a quality NMES unit. You should always choose the best device based on your needs, lifestyle, and quality of the product. Make sure to read the reviews of each device available online and only focus on reputable companies that have a history in the field. Don't be tempted to be drawn in by a bargain, but instead go for the products most endorsed by people you’d trust such as top athletes, gym owners, and selected coaches. The diPulse kits have been recognized as innovations in the NMES field and are widely used by professional athletes, fitness enthusiasts, and certified fitness coaches all over the world.

I am an athlete. What are the benefits of integrating NMES into my everyday routine?

NMES technology is unique as it optimizes the benefits of training to the extreme. It is a non-invasive training and workout system that provides an extra boost to your everyday training workouts without the need for weights. It can also help you can enhance muscle performance through a variety of programs focused on strength and endurance whilst avoiding any extra stress to your joints. Finished your workout? A diPulse NMES kit can help you minimize post-training fatigue or assist you in overcoming those training plateaus that limit your performance.
