The Mini TENS 2 Channel Electrotherapy Device is a portable physiotherapy machine used for relieving pain and stimulating muscles using low-frequency electrical impulses. It works by sending controlled electrical signals through electrode pads placed on the skin, helping block pain signals and promote natural healing. This device features dual-channel output, allowing treatment of two body areas simultaneously, making it highly efficient for both home users and physiotherapists. TENS (Transcutaneous Electrical Nerve Stimulation) therapy is widely used for managing conditions like back pain, arthritis, muscle strain, and joint pain. It is a non-invasive and drug-free pain relief method that is safe for regular use under proper guidance.
