  1. A patient presents with weakness of wrist extension, finger extension, and sensory loss over the dorsal hand. Which nerve is most likely injured?

    Answer: Radial nerve

    The radial nerve innervates the extensor muscles of the wrist and fingers, and its injury causes wrist drop with dorsal hand sensory loss.

  2. The normal resting position (loose-packed position) of the glenohumeral joint is:

    Answer: 55° abduction and 30° horizontal adduction

    The resting position of the glenohumeral joint is approximately 55° abduction and 30° horizontal adduction, where joint congruency is minimal.

  3. Which of the following best describes the 'capsular pattern' of the hip joint?

    Answer: Internal rotation and abduction most limited, then flexion

    The hip joint capsular pattern shows greatest limitation in internal rotation and abduction, followed by flexion, as defined by Cyriax.

  4. Sensory testing using a 10-gram monofilament is most commonly used to assess:

    Answer: Protective sensation and peripheral neuropathy

    The 10-gram Semmes-Weinstein monofilament is used to screen for loss of protective sensation, particularly in diabetic peripheral neuropathy.

  5. According to the ICF (International Classification of Functioning, Disability and Health) model, 'activity limitations' refer to:

    Answer: Difficulties an individual has in executing tasks

    Activity limitations in the ICF model are difficulties an individual has in executing activities, representing the individual level of functioning.

  6. The vastus medialis oblique (VMO) is emphasized in rehabilitation primarily because it:

    Answer: Provides the last 15° of knee extension and patellar stabilization

    The VMO is critical for terminal knee extension and medial patellar stabilization, making it a key target in patellofemoral rehabilitation.

  7. When applying therapeutic ultrasound, a Beam Non-Uniformity Ratio (BNR) closer to which value indicates a safer, more uniform output?

    Answer: 1:1

    A BNR of 1:1 is ideal, indicating perfectly uniform output; clinical ultrasound units typically range from 2:1 to 6:1, with lower values being safer.
