The high voltage pulsed galvanic stimulator (HVPGS) delivers a high voltage, low amperage, short duration electrical current as a twin-peak monophasic waveform up to 300 volts to produce both mechanical muscle contractions and chemical changes in the body. It has been used clinically for over 45 years to treat various musculoskeletal conditions through analgesia, muscle stimulation, and wound healing. The high voltage allows for deep tissue penetration without risk of tissue damage due to its low total current. Typical treatments last 30-40 minutes, 3 times per day.

- 1. HIGH VOLTAGE PULSED GALVANIC STIMULATION Dr. Deepak Anap Asso. Professor
- 2. ļ The high volt pulsed galvanic stimulator (HVPGS), a type of neuromuscular stimulator is a short duration (microsecond), microamperage current driven by a high voltage current (up to 300 volts) that is delivered as a twin-peak monophasic waveform of fixed duration (100 microseconds). ļ This direct current can produce both a mechanical contraction and a chemical change within the body.
- 3. High Volt Pulsed Galvanic Current (HVPGC) ļ® While used clinically over the last 45 years, this type of stimulation and its applications have received much more attention in the last five years. ļ® Typical indications for use include a wide range of clinical problems where high voltage may be applied alone or in combination with other modalities.
- 4. ļ® HVPGS is the use of a high driving voltage (up to 500V) to produce analgesia, muscle contractions, and to facilitate wound healing. ļ® Galvanic stimulation combines very short pulse duration (of constant intensity) and high peak voltage, yet low total current per second, to give relative comfort and avoid tissue damage while stimulating deep tissues. It is also an efficient means of exciting nerve fibers.
- 5. ļ® It allows for deeper penetration. ļ® It does not burn (low amps). ļ® It flows between each pad and dispersive pad (usually placed on large muscle group). ļ® It can be used in water. It has the ability to move fluids. Is used for open wounds, burns and over scar tissue. Can be used on metal implants.
- 6. Physiological effects ļ® Maintaining or increasing range of motion. ļ® Re-educating muscles. ļ® Edema/swelling/inflammation reduction. ļ® Reducing motor spasticity. ļ® Increasing local blood circulation to injured area and promoting fluid movement to and from treatment area.
- 7. ļ® Preventing or retarding muscle disuse atrophy. ļ® Managing chronic/post-traumatic/post- surgical pain conditions allowing patient to participate in their pain management program. ļ® Stimulation and acceleration of wound healing by promoting blood circulation to wound.
- 8. INDICATIONS ļ® Adhesive Capsulitis ,Bursitis ļ® Wound Healing,Odema ļ® Cervical Sprain/Spasm ļ® Degenerative Disc,Sciatica ļ® Epicondylitis ļ® Lumbosacral Sprain ļ® Shoulder Subluxation,TMJ ļ® PostOperative conditions- Arthroscopy,Discectomy,Spinal Fusion
- 9. Duration ļ® Minimum of 30-40 mins /3xday Application ļ® The positive pad is like ice, tending to reduce circulation to the area under the pad and reduction in swelling. The negative pad is like heat, promoting increased circulation, reportedly speeding healing.
