Physical therapy electrode pads are auxiliary devices designed to facilitate physical therapy by adhering to the skin's surface and transmitting electrical pulse signals; they are commonly used to alleviate pain, improve blood circulation, or promote muscle rehabilitation. Their primary function involves stimulating nerves or muscles using low-frequency currents to regulate local tissue metabolism, thereby aiding in the treatment of chronic pain or sports-related injuries.
Principle of Electrical Stimulation: The electrode pads transmit low-frequency currents-generated by a connected device-into the human body, stimulating nerve endings or muscle fibers to block the transmission of pain signals or to induce muscle contraction and relaxation.
Material Characteristics: Typically composed of a conductive gel layer, an adhesive layer, and a backing material, these pads must possess both biocompatibility and stable electrical conductivity.
