SWD (short wave diathermy) is a deep heating agent with heat being generated from the convection of electromagnetic energy emitted from the diathermy elctrode to mechanical energy from the body.
When using iontophoresis to enhance the transcutaneous permeation of ionic drugs into the skin, what polarity must the treating electrode be in relationship to the drug?
a. there is no relationship between the polarity of the medication and the treating electrode
b. the polarity of the medication and the treating electrode should be the opposite of each other
c. as long as the electrode with the medication is hydrated, it makes no difference what polarity the treating electrode is
d. the polarity of the medication and the treating electrode should be the same
What could be the potential cause for a patient not feeling electrical stimulation underneath one of the electrodes during the treatment?
a. significant body hair under one electrode increases impedence and decreases flow from electrode to skin
b. the current density may be too low under one of the electrodes
c. the patient may have decreased sensation under one of the electrodes
d. Oily skin may decrease ability of electrode to adhere to skin
Define: injury resulting in decreased intrinsic joint stability and pain
a. bursitis
b. muscle strain
c. Ligament strain
d. plantar fasciitis
A PTA is applying continuous ultrasound to the quadricep muscle and increases the intensity of ultrasound.

b. increase treatment time
c. warn patient that sensation may feel somewhat hot
d. warn pt. that sensation may feel colder
e. increase speed of movement of the transducer soundhead
When current density when two electrodes from one channel of an electrical stimulation unit are of different sizes the concentration of electricity goes to the larger electrode.
