Electrical muscle stimulation (EMS) treatment is a form of physical therapy and muscle spasm treatment that uses electrical impulses to stimulate the muscles. This type of therapy can be used to relieve pain, improve blood circulation and promote healing. Electrical muscle stimulation (EMS) is a type of electrotherapy stimulates a muscle contraction using electrical impulses in order strengthen weak muscles, reduce swelling, relieve pain and help heal wounds.The IC based Diagnostic cum Therapeutic unit, suitable for taking S.D. Curve is a marvel of electronics. The combination unit produces five different types of stimulating current i.e. Tens, Galvanic, Interrupted Galvanic, Faradic & Surged Faradic for S.D. Curve plotting and therapeutic use Output is smoothly adjustable from 0-135 volts. The stimulating current outputs are as under: GALVANIC. : Continuous well filtered D.C upto 135 volts for a maximum of 0-75mA load. INTERRUPTED-GALVANIC: Pulse duration -0.01, 0.03, 0.1, 0.3, 1, 3, 10, 30, 100, 300 m secs. Frequency 6, 18, 30 per minute 1, 3, 5, 10, 30, 50, 100 per sec. SURGED FARADIC. : Faradic pulse of 0.6 m sec duration, Contraction duration: 2 - 4 seconds. FARADIC: Comprises of 80 pulse per second, each pulse of 0.6 ms width. .MD063
