HIGH VOLTAGE PULSED
Dr. Deepak Anap
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
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
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
Maintaining or increasing range of motion.
Reducing motor spasticity.
Increasing local blood circulation to injured
area and promoting fluid movement to and
from treatment area.
Preventing or retarding muscle disuse
surgical pain conditions allowing patient to
participate in their pain management
Stimulation and acceleration of wound
healing by promoting blood circulation to
Minimum of 30-40 mins /3xday
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
