Interferential therapy is a type of ‘electrical stimulation therapy’ that uses low-frequency electrical currents to stimulate muscles and nerves. This type of therapy helps in reducing pain, swelling, and muscle spasms in the muscular system, as well as promotes healing, thus improving the range of motion of the body. Interferential therapy is often used to treat a variety of conditions, including arthritis, sciatica, and ‘carpal tunnel syndrome’. The treatment involves placing electrodes on the skin over the affected area, which then sends electrical impulses deep into the muscle tissue. The treatment is done in prescribed sessions followed by certain exercises, thus can provide relief from muscular pain and other symptoms.
