HIGH VOLTAGE PULSED

GALVANIC STIMULATION

Dr. Deepak Anap

Asso. Professor

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).

This direct current can produce both a

mechanical contraction and a chemical

change within the body.

High Volt Pulsed Galvanic Current (HVPGC)

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.

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.

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.

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.

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.

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

Duration

Minimum of 30-40 mins /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.
