Q

If a patient presents w/ chronic pain over a small area what Interferential Current would be used?

A

Premod; 1-15 Hz

17
Q

If a patient presents w/ acute pain over a large area what Interferential Current would be used?

A

True IF, 60-150 Hz

18
Q

If a patient presents w/ sub-acute pain over a large area what Interferential Current would be used?

A

True IF, 60-120 Hz

19
Q

If a patient presents w/ chronic pain over a large area what Interferential Current would be used?

A

True IF; 1-15 Hz

20
Q

What is the intensity level for Interferential Current?

A

Patient comfort

21
Q

If a patient presents w/ LBP starting 2 days ago, what Interferential Current would be used and what is the pad placement?

A

True IF; crisscross 4 pads @ 60-120 Hz

22
Q

If a patient presents w/ ankle pain starting 8 weeks ago, what Interferential Current would be used and what is the pad placement?

A

Premod; 2 pads at either side of pain @ 0-15 Hz

23
Q

Please list 3 primary treatment frequencies and the associated clinical goal for each frequency and the associated clinical goal for each frequency along w/ each frequency along w/ target tissues?

A
  • -High Frequency (60-120 Hz) = Tx for acute pain
  • -High/Low Frequency (0-150 Hz) = Tx for acute pain
  • -Low Frequency (0-15 Hz) = Tx for chronic pain
24
Q

How many channels are used during a pre-mod application? How many electrodes? Where are the electrodes placed?

A

1 channel; 2 electrodes; 1 electrode on each side of pain

25
Q

How many channels are used during an Interferential application? How many electrodes? How are the electrodes placed on the patient?

A

2 channels; 4 electrodes; electrodes are placed in a criss-cross pattern

26
Q

Other than the difference in the number of channels/electrodes, what is the difference between pre-mod and Interferential therapy?

A

Pre-mod interference and Interferential therapy

27
Q

Name one reason why pre-mod may be preferable to Interferential in the treatment of your patient?

A

Pre-mod doesn’t penetrate tissue as deeply and is more accurate

28
Q

What should be your guideline in determining the intensity setting for pre-mod and Interferential?

A

Type of pain (acute, subacute, chronic)
