What You'll Learn

Muscle stimulators for pain relief
Muscle stimulators, also known as e-stim, use electrical pulses to stimulate injured muscles and manipulate nerves to reduce pain. The two main types of e-stim are transcutaneous electrical nerve stimulation (TENS) and electrical muscle stimulation (EMS). TENS uses a low-voltage electrical current to block pain or change one's perception of it. It is a non-invasive method of pain relief that is often used to treat short-term or long-term pain. TENS therapy usually helps ease pain during treatment, but the level of pain relief after the session varies from person to person.
EMS uses a stronger current than TENS to get muscles to contract. The unit's electrodes are placed on the skin near the affected muscles, causing rhythmic contractions. This can improve muscle strength if the user attempts to contract the muscle simultaneously. EMS is predominantly used for muscle strengthening and recovery, while TENS is used for pain relief.
Some devices deliver both EMS and TENS currents, while others only deliver one or the other. If you are looking for pain relief, it is recommended to opt for a device that includes TENS. For heavier-duty pain, functional electrical stimulation (FES) may be recommended. FES is specifically designed to assist individuals with neurological conditions or spinal cord injuries.
The Therabody PowerDot 2.0 Uno is a highly-rated muscle stimulator that offers programs for muscle recovery, performance, wellness, and pain management. The device is lightweight, easy to use, and connects to a smart app via wireless Bluetooth. The Compex Performance 3.0 Muscle Stimulator is another option that includes multiple settings tailored for strength, endurance, recovery, and pain relief. The unit is compact and has a silicone case that prevents water damage and improves grip.
