Physiowell Electronic muscle stimulation (EMS) is a physical therapy and fitness technique. Like TENS, it involves a machine that transmits electrical impulses through electrodes that are applied directly to your skin. Unlike TENS, though, the electrodes from an EMS machine are applied to key muscle groups. The IC based musle stimulater Diagnostic with timer 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: 1- 10seconds. FARADIC: Comprises of 80 pulse per second, each pulse of 0.6 ms width.
