GLOSSARY OF TERMS ASSOCIATED WITH HPVS

• Active Electrode – Electrode that carries negative electrical current (cathode).
• Decay Time – The time for the trailing edge of the phase to return to the baseline from the peak amplitude of the phase.
• Decubitus Ulcers – Wounds resulting in prolonged sitting or lying becoming inflamed and ulcerated.
• Direct Current (DC) – An uninterrupted flow of charged particles that flows in one direction.
• Dispersive Electrode – Electrode that carries positive electrical current (anode), generally twice the size of the Active Electrode. Also known as “inactive” or “reference” electrode.
• Interpulse Interval – Is the elapsed time between successive pulses.
• HVPC – High Volt Pulsed Current – Electrical Stimulator that has a monophasic waveform with phase durations usually less than 100 uS that employs a high-driving voltage (usually higher than 150 Volts).
• HVPGS – High Volt Pulsed Galvanic Stimulation – Electrical Stimulator that has a monophasic waveform with pulse durations that are infinite.
• Monophasic – Pulse that deviates in one direction from the zero current baseline and returns to the baseline after a finite period of time.
• Peak Current – The maximum amplitude/magnitude of current with reference of the baseline measured in Milli amplitude.
• Phase – Is the current flow in one direction for a finite period of time. In a monophasic waveform, phase and pulse are identical.
• Polarity – Electrical condition of either positive or negative from base line.
• Pulse – Is an isolated electrical event separated by a finite time before the next event.
• Pulse Amplitude – The measure of the magnitude of current with reference to the base line measured in Milli amplitude or Micro Amplitude.
• Pulsed Current – The unidirectional flow of charged particles that periodically ceases for a finite period of time before the next event.
