High Voltage Pulsed Current (HVPC)
This current type has a twin peak monophasic waveform with
a fixed duration of 64 µs between the two voltage peaks. The amplitude is adjusted in volts rather than in mA. The
short rise time and short duration of each voltage peak (approximately 7 µs) is well suited to nerve stimulation and
efficient discrimination between sensory, motor and pain responses. The very short pulse duration of high voltage
creates a stimulation which is quite comfortable, and one which most patients can tolerate. The very short pulse
duration followed by a very long interpulse interval eliminates the formation of any appreciable chemical or thermal
effects in the tissue. High voltage Pulsed Current is used for stimulating nerves and muscles, causing muscle
contractions. Examples for clinical use are to treat acute or chronic pain, and increase circulation. Muscle contraction
or motor response of isolated muscle groups, superficial or deep, can be easily and comfortably stimulated. For patient
comfort and to prevent accommodation, the Burst frequency can be can be varied through modulation.
Although not a continuous type of direct current (DC), HVPC is a pulsed unidirectional currents, which is unique in
that it produces a polarity in the tissue. Therefore the end user has the ability to select a polarity of the electrode set
up. The pulsing of the HVPC is done to reduce any chemical effects of the polarity in order to decrease skin irritation.
Stop treatment immediately if patient complains of any pain, stinging or burning sensations under the electrodes
