  1. During gait, which phase requires the most hip extensor muscle activity?

    Answer: Loading response

    During loading response (early stance), the hip extensors eccentrically control forward trunk lean.

  2. A patient has a positive Phalen's test. Which condition does this suggest?

    Answer: Carpal tunnel syndrome

    Phalen's test (sustained wrist flexion causing paresthesias) is a clinical screen for carpal tunnel syndrome.

  3. The end-feel for a normal elbow at end-range extension is:

    Answer: Hard (bony)

    Normal elbow extension has a hard (bony) end-feel due to olecranon process contacting the olecranon fossa.

  4. Which muscle is responsible for scapular upward rotation during shoulder elevation?

    Answer: Serratus anterior

    The serratus anterior and upper/lower trapezius form the force couple responsible for scapular upward rotation.

  5. Normal hip abduction range of motion is approximately:

    Answer: 30–45°

    Normal hip abduction ranges from approximately 30° to 45° in a typical adult.

  6. Coxa vara refers to a hip angle of inclination that is:

    Answer: Less than 120°

    Coxa vara is defined as a neck-shaft angle less than 120°, causing relative limb shortening.
