ESS 2 : Electrical Stimulation II

High Volt Galvanic Stimulation/High Volt Pulsed Current is used for what three things?

edema reduction, dermal wound healing, reduction of pain

HVPC is ____ voltage output and ______ pulsed waveforms and _____ currents

high, monophasic, pulsed.

what are the two ways that HVPC manages edema?

local muscle pumping action, fluid repulsion

how does HVPC modulate pain?

via that gate theory

HVPC helps strengthen dermal wounds by strengthening and mimicking the ____ _____

skin battery

what is the skin battery?

natural current that flows between the dermis and epidermis and helps maintain tissue health

if a wound is infected, what charge of HVPC would be used?

negative

what polarity should you use for a wound that does not have an infection?

positive

HVPC high voltage:

>150

Low voltage pulsed currents is good for what?

muscle strengthening

HVPC pulse duration

sum of the duration of both spikes plus inter-side interval.

HVPC general pulse duration:

100-200 microseconds

HVPC frequency:

1-200pps (hertz)

does HVPC encounters what level of tissue impedance? how does it effect the patient?

low tissue impedance, comfortable for patient

edema is ___ charged

negatively, -

how would you set up pads for edema reduction?

monopolar set up, cathode (-) pad over the stolen area and anode pad closer to the heart so that the fluid is pulled back into circulation

what will the pulse frequency be for edema reduction?

as high as possible

edema reduction PD is manipulated how?

not manipulated!

edema reduction applications ______ mode, and _____ min duration

continuous, 30-60

when reducing swelling via muscle pumping/contractions the PF is ____, amplitude is until ____ _____ and the on and off time is typically ___ _____ for ________ minutes.

1-10 pps, motor response, 15/45s 30-60
