Health Expert Electronic Stimulator," a foot massager that uses electrical muscle stimulation (EMS) or transcutaneous electrical nerve stimulation (TENS). It uses electrical impulses delivered through the mat to cause muscle contractions or interfere with nerve signals for pain relief. The device includes a main unit, a remote control, and a USB charging cable. EMS can help reduce muscle fatigue and soreness, increase range of motion, and is used for strength training or rehabilitation. TENS is used specifically for pain therapy, treating chronic or acute pain by blocking pain signals to the brain and stimulating natural painkillers.
