You can use it multiple times daily (2-3 times per area suggested), with each session lasting 15-60 minutes. The frequency depends on your training goals and rehabilitation needs. Levina can be incorporated into daily training or rehabilitation programs, suitable for muscle recovery after various intensity workouts and relieving acute or chronic pain. If you have specific health conditions, are pregnant, or have concerns about product use, please read the manual carefully or consult a professional or fitness expert before use.
TENS is generally safe; however, some individuals may experience skin irritation or mild discomfort. If persistent discomfort occurs, please discontinue use and consult a healthcare professional.
TENS is often used as part of a comprehensive chronic pain management plan. Individual responses may vary.
TENS is often used to alleviate musculoskeletal pain. However, migraines are NOT within Levina's indications.
It shouldn't cause discomfort. Start with lower intensity adjustments. For EMS, gradually increase to the maximum tolerable intensity without discomfort, aiming for maximal muscle contractions.
The maximum muscle contraction attained through EMS stimulation falls within a safe range, avoiding muscle strains or ruptures. However, excessive use may lead to muscle fatigue due to prolonged or frequent contractions.
Based on clinical evidence, EMS can enhance overall training and recovery effects, including:
(1) Improves muscle strength and endurance through targeted muscle contractions.
(2) Facilitates muscle recovery post-injury or surgery.
(3) Enhances blood circulation, aiding in nutrient and oxygen delivery to muscles.
(4) Alleviates muscle pain and stiffness after intense exercise.
(5) Improves joint mobility and flexibility through peripheral muscle engagement.
(6) Increases training efficiency by providing targeted muscle stimulation without traditional resistance training.
(7) Reduces muscle fatigue, enabling longer and more effective workouts.
It's important to follow usage guidelines and consider individual health conditions. While EMS provides many benefits, regular exercise and a healthy lifestyle are also essential.
(1) Academic Journals: Sports science and fitness journals regularly publish research and applications of EMS in sports.
(2) Professional Books: Exercise physiology and rehabilitation texts may cover EMS applications.
(3) Academic Institution Websites: Websites of universities or research institutions may have research and articles related to EMS applications in sports.

Levina's menstrual pain relief mode uses High-Frequency TENS to block pain signals from the lower abdomen or lower back to the brain. It also stimulates the release of endorphins, the body's natural pain-relieving hormones.
The menstrual pain relief mode is clinically proven and distinct from typical low-frequency TENS (2-5Hz). It utilizes high-frequency TENS (>50Hz), specifically designed to alleviate menstrual pain. Studies indicate that better relief is achieved under modulation parameters of 100Hz and 100ms.
Research suggests that the minimum effective treatment time for menstrual pain relief is 20 minutes, with no limitation on usage frequency as needed for pain relief. Levina's menstrual pain relief mode is preset for 30 minutes. If additional relief is needed, you can safely proceed with another session. Currently, there is no evidence indicating that prolonged use is unsafe.
However, we do not recommend using the device while sleeping, as you should always be aware of your body's response to the stimulation.
The use of high-frequency HF TENS for menstrual pain relief has undergone numerous clinical trials over the past two decades and has been validated. According to scientific research, electrical stimulation for menstrual pain relief can be combined with other treatments such as heat therapy or medication. Levina offers more options compared to any other TENS device, allowing individuals to freely address their pain needs. The benefits of this flexibility include wireless control, adjustable intensity, and the ability to use it as needed throughout the day.
We suggest drinking warm water or tea to ease cramps. If pain persists, it may be due to other physiological or health factors, and we recommend scheduling a consultation with a medical professional promptly.
Conditions like endometriosis, PCOS, and uterine fibroids differ from common menstrual pain (primary dysmenorrhea). For individuals diagnosed with these conditions, we recommend consulting a doctor or medical professional before use.
Yes, Levina can be used with a copper IUD. However, if you have any concerns, consult a doctor or healthcare professional before use.
We do not recommend using it during pregnancy. Research shows that TENS can be helpful in reducing labor pain, but we advise consulting a medical professional.
The menstrual pain relief mode utilizes Transcutaneous Electrical Nerve Stimulation (TENS), which is a sensory stimulation targeting nerves beneath the skin. There is no evidence to suggest that TENS affects egg quality or has negative effects on reproductive health. However, if you have any concerns about its impact on reproductive health, we always recommend consulting a doctor or healthcare professional before use.
