CCAT Rehabilitation Techniques & Modalities 2

Question 1

Which parameter of therapeutic ultrasound primarily determines the depth of tissue penetration?

Accepted Answer

Frequency (MHz)

Answer

Lower frequencies (1 MHz) penetrate deeper tissues (up to 5 cm), while higher frequencies (3 MHz) target superficial tissues (up to 2 cm).

Question 2

What is the primary purpose of using a moist heat pack before performing manual therapy on a dog?

Accepted Answer

To increase tissue extensibility and reduce muscle guarding

Answer

Moist heat increases tissue temperature, improves collagen extensibility, and reduces muscle guarding, making subsequent manual therapy more effective.

Question 3

During neuromuscular electrical stimulation (NMES), which fiber type is recruited first at low stimulation intensities?

Accepted Answer

Type I slow-twitch oxidative fibers

Answer

NMES recruits motor units in reverse order compared to voluntary contraction, with Type I slow-twitch fibers recruited at lower intensities.

Question 4

A cat recovering from hindlimb paresis is placed in an underwater treadmill. Which benefit is MOST specific to this modality compared to land-based walking?

Accepted Answer

Reduced joint loading with maintained gait pattern

Answer

Buoyancy in underwater treadmill therapy reduces joint compressive forces by up to 60%, allowing weight-bearing exercise with less pain and joint stress.

Question 5

What is the correct tissue response when laser therapy is applied at photobiomodulation doses?

Accepted Answer

Increased ATP production and cellular metabolism

Answer

Photobiomodulation at therapeutic doses stimulates cytochrome c oxidase in mitochondria, increasing ATP production and promoting cellular repair.
