Electric stimulation treatment involves the administration of electrical stimulation to treat muscle spasms and pain. Athletes to enhance performance also use electric stimulation. Electrical stimulation treatment is effective in providing quick relief to sports strain or injury. The administration of electric current improves blood circulation and strengthens the muscles. Some blood vessels in the body are very thin. When an individual exercises the muscles in the area, they swell and cut off blood supply to these capillaries. Electrical impulse helps in removing the blockage and reinstating the blood flow to the arteries. This helps in alleviating pain and discomfort. Electric stimulation treatment also finds use in the treatment of chronic and acute pain. Electrodes attached to the patient's skin deliver electric currents of specified strength to the affected area. This stimulation causes contraction of the target muscles to relieve pain. Electrical stimulation is beneficial in increasing the range of motion and improves the circulation in the body. It is used in treating conditions like sprains, arthritis, back pain scoliosis and sciatica. Various types of electrical stimulation treatments are available. Transcutaneous electrical neuromuscular stimulation is used to alleviate chronic pain. Interferential current (IFC) is prescribed for decreasing inflammation and swelling of affected tissues. Galvanic stimulation is another type of electric stimulation. It differs with TENS and IFC in that it uses direct current rather than alternating current. Electric stimulation should not be prescribed to patients with pacemakers and pregnant women should also avoid this treatment.
