Q

Studies support that e-stim facilitates would ____ of chronic wounds

A

healing

18
Q

How does e-stim facilitate wound healing? (Hint: There’s three reasons)

A
  1. Improves percentage and weekly change in ulcer size
  2. Increases likelihood of complete wound closure
  3. Saves health care costs
19
Q

E-stim can be used to control ____

A

edema

20
Q

When using e-stim to control edema due to inflammation, the (positive/negative) polarity HVPC retards formation of (acute/chronic) edema

A

negative; acute

21
Q

True or False:

When treating a patient with e-stim due to inflammation, the area being treated will be cold, pale, and swollen

A

false it will hot, red, and swollen.

Edema due to a lack of muscle control will be cold, pale and swollen

22
Q

When using e-stim to treat a patient with edema due to inflammation, the negative charge repels (negative/positive) charged serum proteins

A

negative

23
Q

When using e-stim to control edema due to inflammation, roughly ____% reduction will be shown; similar magnitude to _____ or cold water immersion

A

50%; ibuprofen

24
Q

When using e-stim to control edema due to lack of muscle control, (unhealthy/healthy) muscles contract to promote ___ return from periphery

A

healthy; fluid

25
Q

When using e-stim to control edema due to lack of muscle control, the area will be (hot/cold), (red/pale), and swollen

A

cold; pale

26
Q

When using e-stim to control edema due to lack of muscle control, it is treated with (motor/sensory) level e-stim and elevation

A

motor

27
Q

When treating a patient for edema control with electrical stimulation, the treatment can be combined with or followed by _____

A

elevation and compression

28

What does HVPC stand for

A

high voltage pulsed current

29
Q

Twin peak wave forms are also _____ waves

A

active

31
Q

In regards to HVPC, the larger electrode is called the (active/dispersive) electrode

A

dispersive

32
Q

True or False:

When treating edema due to lack of muscle control, a clinician should use pulse biphasic or russian protocol

A

true

33
Q

Where would the electrode placement be when treating edema that’s due to lack of muscle control

A

on muscles around main veins draining the area

34
Q

What is the on:off time of ES treating edema due to lack of muscle control

A

one to two seconds on, then one to two seconds off

35
Q

_____ is the use of low amplitude DC to facilitate transdermal drug delivery

A

iontophoresis

36
Q

Iontophoresis is the use of a (low/high) amplitude DC to facilitate transdermal drug delivery

A

low

37
Q

Iontophoresis is the use of a low amplitude (AC/DC) to facilitate transdermal drug delivery

A

DC

38
Q

Iontophoresis is based on the principle that like charges (attract/repel)
