NENRENT EMS/TENS Foot Stimulator User Manual

Model: AST-300W

Introduction

The NENRENT EMS/TENS Foot Stimulator is an electronic device designed to provide relief from muscle pain, neuropathy pain, swollen feet, stiffness, cramps, and numbness, while also improving blood circulation. It utilizes two clinically proven physical therapies: Electrical Muscle Stimulation (EMS) and Transcutaneous Electrical Nerve Stimulation (TENS).

EMS works by mimicking the body's bioelectrical signals, stimulating muscle contractions to improve blood circulation, muscle strength, and recovery. TENS targets specific muscle groups with low-frequency pulses, disrupting pain signals and stimulating the release of dopamine to alleviate various types of pain, including neuropathy, chronic acute, and arthritis pain.

This device is intended for home use to help reduce feet, leg, and calves fatigue.
