QUESTIONS AND
ANSWERS 2026 - 2027
T/F: Isometric contractions should be performed during the 10 seconds
of stimulation - ANSWERS-True
patient contracts with the machine
T/F: Isometric contractions are done at mid ROM. - ANSWERS-True
This is where the muscle is the strongest.
T/F: Russian stimulation takes a normal muscle and increases strength -
ANSWERS-False--not a normal muscle, but an atrophied muscle
Constant changing of the treating frequency results in decreased
_____________ - ANSWERS-accommodation
this is known as modulation and can be accomplished by scanning or
sweeping a frequency range with IF only.

QUESTIONS AND
ANSWERS 2026 - 2027
Physiological Effects of Microcurrent - ANSWERS-Increase ATP
Increase AA (protein synthesis)
Thus, it increases healing.
Decreases pain (via healing tissue)
Indications for microcurrent - ANSWERS-musculoskeletal injuries (for
healing!)
Frequency for microcurrent - ANSWERS-below 1 Hz (0.5-0.3 Hz)
Intensity for microcurrent - ANSWERS-BELOW patient perception---
patient should never feel it!
Tissue healing for microcurrent - ANSWERS-200 and 800 micro amps
Action of Cold Lasers - ANSWERS-Decrease inflammation
Decrease pain
