Electrotherapy is the use of electrical energy as a medical treatment. In medicine, the term electrotherapy can apply to a variety of treatments, including the use of electrical devices such as deep stimulators for disease.
Surguin distributes a wide range of professional electrotherapy devices for physiotherapy & rehab, including ultrasound devices, stims, TENS, NMES, IFC, high volt, microcurrent, combination therapy units, vacuum units, high intensity and low level lasers, shockwave therapy, electrodes, leads and wires, gels and disinfectants.
TENS (Transcutaneous Electrical Nerve Stimulation) units use either low frequencies (2-4 Hz) or high frequencies (80-100 Hz) to block pain impulses to the brain. This helps the body produce more natural pain relieving substances and increase blood flow to the area - both help relieve pain. Relief can last for hours.
EMS units (Electrical Muscle Stimulation) help reduce or prevent muscle atrophy, the weakening and then loss of muscle tone that happens after injuries or surgery. It helps increase blood flow and range of motion and increase muscle strength and endurance. It can also help with pain management by assisting in relieving muscle pains from spastic muscles, tight muscles or sore muscles. EMS signals penetrate deeper than TENS signals and the frequency is usually above 200 Hz.
IFC units (Interferential Current) is a deeper TENS. It modulates at a high carrier waveform frequency of about 4000 Hz which penetrates deeper and with less user discomfort. In the tissues the waveform is canceled out which produces a TENS like signal deep under your skin. These units are used to reduce swelling and pain, speed healing and restore muscle function. If you have not found relief with a TENS unit, anecdotal evidence suggests an IFC unit may help more effectively.
