Definition[edit | edit source]

High Voltage Pulsed Galvanic Current (or High Voltage Galvanic Stimulation) is a type of electrical current in which high voltage is applied with low frequency and low pulse duration. [1] It has been widely used in physiotherapy for its analgesic and muscle strengthening (for innervated muscle) effect. [2][3]

Clinical Usage[edit | edit source]

Evidence for the effect of High Voltage Pulsed Galvanic Current (HVPGC) for various diagnoses exists:

  • Wound Healing: The application of HVPGC is safe and effective in treating stage II chronic dermal ulcer [4], and stage IV decubitis ulcers [5] in human.
  • Multiple Sclerosis (MS): A non-randomized controlled trial showed that spasticity-associated weakness in knee flexors and ankle dorsiflexors, and fatigue can be improved after HVPGC treatment in MS patients. [6]
  • Myofascial Pain Syndrome: HVPGC is effective in the treatment of trigger points in myofascial pain syndrome and its useful effects continue in the midterm follow-up. [7]
  • Levator Ani Syndrome: A study showed that 50% of 28 patients with Levator Ani Syndrome had pain or symptom relief, or both, after an average of eight treatment sessions consisting one hour of HVPGC applied through a rectal probe, at a frequency of 120 Hz, and at an intensity to the patient's maximum tolerance. [8]
  • Patellofemoral Pain Syndrome (PFPS): Additional HVPGC application in PFPS rehabilitation may decrease pain levels during activities including step up and down while functional status remains the same. [9]


There is also evidence regarding choosing the best parameter to apply HVPGC:

  • The application of HVPGC for 60 and for 120 min, seven days a week proved to be the optimal duration for treating chronic dermal ulcers. [10]

The video below is about correct parameter selection and electrode placement in the use of HVPGC in wound care and oedema control.

[11]

According to some studies that compared the HVPGC to other treatment methods;

  • The HVPGC treatment caused a significant reduction in burn wound surface and hydroxyproline content compared to ultrasound treatment which has been widely used for wound healing. [12]
  • HVPGC is not as effective as isometric exercise in increasing strength in quadriceps femoris muscle. [13]
