A major scientific review analyzing 381 clinical trials with over 24,000 participants confirms that TENS (Transcutaneous Electrical Nerve Stimulation) significantly reduces both acute and chronic pain during or immediately after use, with no serious side effects. Whether the pain is from sore muscles, arthritis, or daily strain, TENS consistently provides safe, drug-free relief when applied with strong but comfortable intensity directly to the pain area — just like Levina Wireless TENS/EMS is designed to do.

A 2023 systematic review and meta-analysis of 26 clinical trials found that whole-body electrical muscle stimulation (WB-EMS) significantly increased muscle strength, improved muscle mass, and reduced body fat in adults of all ages—even with as little as one to two 20-minute sessions per week. Participants experienced measurable gains in lean muscle and strength, whether they were active or sedentary. WB-EMS is a time-saving training method that delivers real physical benefits with no serious side effects.

A 2024 randomized controlled trial published in Archives of Physical Medicine and Rehabilitation found that using a wearable TENS device helped patients aged 50+ with chronic knee pain significantly reduce pain within the first week of use. When combined with gentle exercise therapy, users also showed improved stair climbing and physical performance, with no serious side effects. The study concluded that TENS helps reduce psychological and physical barriers to exercise—making wearable TENS, like Levina JointVive, a valuable tool for at-home rehab.

According to the American Family Physician journal, high-frequency TENS is an effective, drug-free way to relieve menstrual cramps. Clinical studies show it reduces both the intensity and duration of pain, while lowering the need for painkillers. TENS is one of the top non-drug methods recommended by physicians for managing primary dysmenorrhea, especially when used at the onset of menstrual flow.

A 2022 double-blind, placebo-controlled study confirmed that a wearable TENS device reduced menstrual pain by over 50% compared to just 5% with a placebo. Pain relief began within 20 minutes and lasted over 7 hours. TENS also reduced painkiller use by 93%—with no serious side effects. Nearly all participants reported high satisfaction and would continue using the device.
