Manufactures Interferential Electro Therapy Unit. Galtron Electromedical Pvt. Ltd. Also offers medical Equipments for Surgery, Urology, Pediatric, Orthopaedic, and Gynaecology. Interferential Electro Therapy Unit reduces the swelling of soft tissues. Ligament sprains, muscle strains and spasma often respond to this treatment, helping to reduce atrophy and increase blood circulation. Tiny amounts of electrical impulses are induced into the tissues near the injury. Where these waves intersect below the surface of the skin, low-frequency stimulation is created. This prompts the body to secrete endorphins and other natural painkillers to help relieve pain.
