Describe the masquerade of pain for acupuncture TENS.

A

up to 5 hours

21
Q

What are the options of electrode placement for TENS?

A

Criss cross, parallel, bracket, unilateral

22
Q

What are the indications for IFC/Pre-Mod?

A

pain control for larger regions, maybe edema control and force production

23
Q

Name some examples of body regions/muscles you may use IFC for.

A

Knee, Quad, Lumbar, Rotator cuff

24
Q

When would use chose Pre-mod?

A

on an area in which 4 may not fit

25
Q

Name an example for pre-mod.

A

IE lateral ankle sprain/wrist/hand

26
Q

What are the options for electrode placement for IFC?

A

criss cross only

27
Q

What will decrease sensory habitation for longer treatment times?

A

sweep mode

28
Q

What allows for change in position of the interference pattern?

A

vector scan

29
Q

Briefly describe how pre-mod is still IFC.

A

it creates the interference using one channel by creating it within the Estim unit

30
Q

What are the indications for for HVPC?

A

wound healing and inflammation/edema

31
Q

What polarity do use choose for edema control?

A

negative polarity

32
Q

What polarity do use chose for tissue healing?

A

positive polarity

33
Q

How would you place the affected problem?

A

elevation

34
Q

Which electrode wire is for the dispersive electrode for HVPC?

A

black

35
Q

Which electrode wire is for the MOA for HVPC?

A

red (positive)

36
Q

Describe the protocol for Hi-volt for tissue healing inflammatory period.

A

60-125 Hz, duration 40-100 microsec, negative polarity, 45-60 few times/day

37

Q

What is the sensation felt during hi volt?

A

strong but comfortable tingling

41
Q

What are the indications for NMES/Russian?

A

generate muscle contraction:
Stimulation of denervated muscles (FES), improve motor control (NMES), strengthening (both), muscle pump for edema control (NMES), reduce spasticity(NMES)

A

no

46
Q

Which fibers do ES have the most effect on?

A

type II
