Warnings
Caution should be used in applying TENS/EMS to patients suspected of having heart disease. Further clinical data is needed to show there are no adverse results.Do not use TENS/EMS during pregnancy.Do not place electrodes on the front of the throat as spasm of the Laryngeal and Pharyngeal muscle may occur.Do not stimulate over the carotid nerve, particularly with patients with known sinus reflex sensitivity.Care should be taken so that when operating potentially dangerous machinery the stimulator controls are not changed abruptly.Cases of skin irritation at the electrode site have been reported. Stimulation should be stopped and electrodes removed until the cause of the irritation can be determined.Electrodes should not be placed over the eyes, in the mouth, or internally.Keep this device out of the reach of children

TENS: “Transcutaneous Electrical Nerve Stimulation”- a safe, non-invasive, drug free method of pain relief used by Physical Therapists and professional Doctors for over decades. By delivering stable pulses to the skin to stimulate nerve fibers, Tens unit could effectively block the pain signal to people’s brain. At the same times, increases natural endorphins, which is a natural pain reliever. In many cases, the reduction or elimination of pain lasts longer than the actual period of stimulation.
EMS: “Electrical Muscle Stimulation” is an internationally accepted and proven way of treating muscular injuries. It works by sending electronic pulses to the muscle needing treatment; this causes the muscle to exercise passively. When the muscle receives this signal it contracts as if the brain has sent the signal itself. As the signal strength increases, the muscle flexes as in physical exercise. When the pulse ceases, the muscle relaxes and the cycle starts over again.
iSTIM EV-804: Digital TENS EMS combo stimulator comes with 2 channels, 5 TENS modes, 2 EMS modes and 24 preset programs, sending comfortable impulses through the skin that stimulate the nerve fibers in the treatment area. Effectively Block the pain signal to your brain! Safe and highly effective stimulation helps for treating chronic or acute pain (e.g. shoulder tension, back pain, arthritic, knee pain) and provides muscle relaxation and muscle strengthening.
JAPANESE ELECTRODE PADS: High-grade, and biocompatible SEKISUI Japanese gel, which facilitates efficient conducting of the electrical stimulator’s current to the patient’s skin in a dispersed manner. 100% SEKISUI Japanese Gel is the harmless ingredients and the best fit for even sensitive skin users.
