NPTE-PT Therapeutic Modalities Application 4

Question 1

A PT uses pulsed shortwave diathermy (PSWD) over a patient's lumbar region. Which tissue type is MOST effectively heated by the inductive coil method?

Accepted Answer

Highly hydrated tissues with high water content such as muscle

Answer

Inductive coil PSWD generates eddy currents most effectively in tissues with high water and electrolyte content, such as muscle.

Question 2

Which electrode placement during TENS application over the cervical spine region is CONTRAINDICATED due to risk of adverse physiological response?

Accepted Answer

Over the anterior neck across the carotid sinus

Answer

Electrode placement over the carotid sinus can trigger a vasovagal response, causing bradycardia and hypotension.

Question 3

A patient with a skin sensitivity complaint after treatment states the skin feels hot and looks red after cryotherapy. Which term describes this paradoxical hunting response?

Accepted Answer

Lewis hunting reaction

Answer

The Lewis hunting reaction is a cyclical vasoconstriction and vasodilation that prevents tissue freezing during prolonged cold application.

Question 4

When using high-volt pulsed current (HVPC) for wound healing, which polarity is typically used in the proliferative phase to promote fibroblast activity?

Accepted Answer

Positive polarity

Answer

Positive polarity HVPC attracts fibroblasts and promotes collagen synthesis during the proliferative phase of wound healing.

Question 5

A PT is selecting ultrasound parameters for treating a superficial trigger point at 1 cm depth in the upper trapezius. Which frequency is MOST appropriate?

Accepted Answer

3 MHz

Answer

3 MHz ultrasound has a shallower depth of penetration (1–2 cm), making it ideal for superficial structures like trigger points near the surface.
