ATC Therapeutic Modalities 3

Question 1

The Arndt-Schultz Law as applied to therapeutic modalities states that:

Accepted Answer

Weak stimuli excite, moderate stimuli enhance, and strong stimuli suppress physiological activity

Answer

The Arndt-Schultz Law states that weak stimuli excite, moderate stimuli enhance, and strong stimuli suppress physiological activity, guiding dosage decisions in therapeutic modalities.

Question 2

The cryostretch technique uses which sequence of therapeutic applications?

Accepted Answer

Ice application until numbness, then stretching, then rewarming

Answer

Cryostretch involves applying ice until the area becomes numb, then performing stretching during the cold-induced analgesia phase to achieve greater range of motion with less pain.

Question 3

Which ultrasound parameter is MOST critical to control when treating tissue adjacent to a metal implant?

Accepted Answer

Spatial average intensity (keep lower)

Answer

Spatial average intensity must be kept lower when treating near metal implants because metal conducts and concentrates ultrasound energy, risking localized tissue damage or burns.

Question 4

Low-level laser therapy (LLLT) exerts its therapeutic effects primarily through which mechanism?

Accepted Answer

Photobiomodulation of cellular metabolic processes

Answer

Low-level laser therapy works through photobiomodulation, where specific wavelengths of light stimulate cellular metabolic processes and promote healing without significant thermal effects.

Question 5

In fluidotherapy, heat is transferred to the body part through which mechanism?

Accepted Answer

Convection

Answer

Fluidotherapy transfers heat through convection, as the warm air-suspended cellulose particles continuously move around the body part, delivering heat to the tissue surface.
