Question 1

What is the purpose of proprioceptive neuromuscular facilitation (PNF) stretching?

Accepted Answer

Question 2

Which special test is used to assess anterior cruciate ligament (ACL) integrity?

Accepted Answer

Lachman test

The Lachman test evaluates ACL integrity by assessing anterior tibial translation on the femur with the knee at 20–30 degrees of flexion.

Question 3

In therapeutic ultrasound, what frequency is typically used for deeper tissue penetration?

Accepted Answer

1 MHz

Answer

1 MHz ultrasound penetrates to a depth of 3–5 cm, making it suitable for treating deep tissues like hip or lumbar muscles.

Question 4

Which principle states that bone remodels in response to mechanical stress placed upon it?

Accepted Answer

Wolff's Law

Answer

Wolff's Law states that bone adapts its structure to the mechanical demands placed on it, becoming denser with loading and resorbing with disuse.

Question 5
