Known allergy to therapeutic ions

Question 3

2 Physiologic Effects of Low Volt Galvanism: Iontophoresis

Answer 3

pushes ion of therapeutic substances through the skin

moves edematous fluid

Question 4

What are the two frequencies used for sensory stimulation and what situations would you use each?

Answer 4

1 to 15 pps: tissue repair

80 to 150 pps: tissue repair, acute edema (fluid shift), acute pain (gate control)

Question 5

What intensity and frequency would you use for Chronic pain relief?

Answer 5

Motor (opiate release)

3-5 pps

Question 6

Using motor intensity, what frequency would you use for tissue healing or chronic edema reduction?

Answer 6

1-10 pps

Question 7

For what conditions would you use 40-60 pps at a motor intensity?

Answer 7

chronic edema reduction (surged contraction)

muscle re-education/strengthening

Question 8

What frequency would you use for reduce muscle hypertonicity, spasm and spasticity?

Answer 8

80-150 pps

Question 9

What is the idea behind using high frequency motor intensity with a hypertonic muscle?

Answer 9

fatigue of the muscle will force it to stop holding tension and release/relax.

What are the two reasons you might bring a person to the nociception intensity level?

Answer 10

acute or chronic pain

Question 11

What two frequencies are used with nociception intensity and what mechanism is involved with each?

Answer 11

1 to 15 pps (opiates)

80 to 150 pps (gate control)
