Question 1

Galvanic means ______. That means that there is a + and - pad, for flow in one direction or the other.

Answer 1

Direct current

Question 2

The __ pole softens tissues, increases nerve irritability, vasodilates, and increases pain.

Answer 2

Negative

Question 3

The __ pole hardens tissue, decreases nerve irritability, dehydrates tissue, vasoconstricts, slows bleeding, and was used for germicidal use back in the day.

Answer 3

Positive

Question 4

The ___ pole is for acute pain, while the ___ pole is for chronic/rehab pain.

Answer 4

Positive, negative

Question 5

____ is used to drive chemical ions into superficial tissue

Answer 5

Iontophoresis

Question 6

An example of iontophoresis is to place a solution of negative niacin ions under the ____ pad to drive the niacin into the tissue

Answer 6

Negative

Question 7

The treatment time for iontophoresis varies from __-__ minutes. The intensity must be very low to prevent chemical burning of the patient.

Answer 7

10-30

Question 8

Low volt galvanic does not really provide thermal therapeutic effects, or enkephalins. It will produce ____ if the current is increased high enough, but this will be very uncomfortable for the patient. So basically, don’t do it.

Answer 8

Muscle contraction

Question 9

Do NOT run the current near ______

Answer 9

Metal implants

Question 10

When a nerve is completely degenerated an alternating current (AC: EMS for example) will give NO contraction. Stimulation with direct current (DC: Galvanic) will produce a ____ contraction, and the point of stimulation will have moved from the motor point to the ends of the muscle near the tendinous junction.

Answer 10

Sluggish
