LECTURE 3

Question 1

What is the waveform of IFC?

Answer 1

Sinusoidal/ Sine

Question 2

What is the waveform of HVPG?

Answer 2

two, twin-peak monophasic pulses

Question 3

How high of voltage is used with HVPG?

Answer 3

500

Question 4

What is the main use of HVPG?

Answer 4

facilitate tissue healing

Question 5

What is “Current of Injury” and what is the polarity that forms within a wound?

Answer 5

Injured tissue has been found to produce a measurable current, positive polarity

Question 6

For the treatment of necrotic tissue, the ___________ electrode is placed over the wound to attract white blood cells such as __________ and ________?

Answer 6

Positive, neutrophils and macrophages

Question 7

Which two modalities use this waveform? purple photo

Answer 7

TENS and NMES

Question 8

Which modality uses this waveform? S shape

Answer 8

IFC - sine

Question 9

Which modality used this waveform? - two mountains

Answer 9

HVPG

Question 10

What is the common set-up of electrodes for IFC?

Answer 10

Criss-cross

Question 11

Why do we use “Scan” or “Sweep” on IFC?

Answer 11

Prevent accommodation

Question 12

Galvanotaxis

Answer 12

A process: negative ions are attracted to a positive pole and positive ions to a negative pole

The application of alternating negative and positive polarities influences the movement of cells. may facilitate wound healing.
