Lab Practical Exam Flashcards
Name 2 indications for Low Volt Galvanism: Iontophoresis
Edema
Muscle Hypertonicity
2 Contraindications for Low Volt Galvanism: Iontophoresis
over damaged skin/skin lesion
Known allergy to therapeutic ions
2 Physiologic Effects of Low Volt Galvanism: Iontophoresis
pushes ion of therapeutic substances through the skin
moves edematous fluid
What are the two frequencies used for sensory stimulation and what situations would you use each?
1 to 15 pps: tissue repair
80 to 150 pps: tissue repair, acute edema (fluid shift), acute pain (gate control)
What intensity and frequency would you use for Chronic pain relief?
Motor (opiate release)
3-5 pps
Using motor intensity, what frequency would you use for tissue healing or chronic edema reduction?
1-10 pps
For what conditions would you use 40-60 pps at a motor intensity?
chronic edema reduction (surged contraction)
muscle re-education/strengthening
What frequency would you use for reduce muscle hypertonicity, spasm and spasticity?
80-150 pps
What is the idea behind using high frequency motor intensity with a hypertonic muscle?
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?
acute or chronic pain
What two frequencies are used with nociception intensity and what mechanism is involved with each?
1 to 15 pps (opiates)
80 to 150 pps (gate control)

pain reduction
selective nerve depolarization
2 physiological effects of microcurrent
increased ATP production and protein synthesis
increases cell membrane transport
2 physiological effects of interferential
depolarize sensory and motor nerve fibers
pain reduction
2 physiological effects of US
vibrates molecules creating heat
cavitation (formation of microbubbles)
2 physiological effects of diathermy
increase cell metabolism
deep heat created by longer waves
2 physiciological effects of infrared light
superfiscial penetration (to treat skin lesions) increased cellular metabolism
