High voltage pulsed galvanic stimulation

This document discusses high volt pulsed galvanic stimulation (HVPGS), a type of neuromuscular stimulator that uses high voltage, low amperage, short pulses to penetrate deep tissues. HVPGS can produce muscle contractions and chemical changes, and is used for analgesia, wound healing, and other clinical applications. It allows for deep penetration without risk of tissue damage. Physiological effects include increased range of motion, edema reduction, and accelerated wound healing. Common indications are adhesive capsulitis, bursitis, cervical sprain, and post-operative conditions. Treatment involves 30-40 minute sessions 3 times per day.

- 2. The high volt pulsed galvanic stimulator (HVPGS), a type of neuromuscular stimulator is a short duration (microsecond), micro-amperage 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). Introduction
- 3. This direct current can produce both a mechanical contraction and a chemical change within the body.
- 4. High volt pulsed galvanic current (HVPGC) general explanation: 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. Typical indications for use include a wide range of clinical problems where high voltage may be applied alone or in combination with other modalities.
- 5. HVPGS is the use of a high driving voltage (up to 500V) to produce analgesia, muscle contractions, and to facilitate wound healing. 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.
- 6. It allows for deeper penetration. It does not burn (low amps). It flows between each pad and dispersive pad (usually placed on large muscle group). 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.
- 7. PHYSIOLOGICAL EFFECTS Maintaining or increasing range of motion. Re-educating muscles. Edema/swelling/inflammation reduction. Reducing motor spasticity. Increasing local blood circulation to injured area and promoting fluid movement to and from treatment area.
- 8. Preventing or retarding muscle disuse atrophy. Managing chronic/post-traumatic/post-surgical pain conditions allowing patient to participate in their pain management program. Stimulation and acceleration of wound healing by promoting blood circulation to wound.
- 9. INDICATIONS Adhesive Capsulitis, Bursitis Wound Healing, Odema Cervical Sprain/Spasm Degenerative Disc, Sciatica Epicondylitis Lumbosacral Sprain Shoulder Subluxation, TMJ PostOperative conditions-Arthroscopy, Discectomy, Spinal Fusion
- 10. Duration Minimum of 30-40 minutes/3xday Application 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.
