Question 1

A patient presents with pain and weakness in resisted elbow flexion and supination, with a palpable 'Popeye' deformity. What is the most likely diagnosis?

Accepted Answer

Distal biceps tendon rupture

Answer

Distal biceps tendon rupture presents with the classic 'Popeye' deformity (proximal muscle belly bunching), weakness in supination and flexion, and often a palpable gap at the cubital fossa.

Question 2

When prescribing a therapeutic exercise program for osteoporosis, which loading type is most effective at stimulating bone formation?

Accepted Answer

Progressive high-impact and resistance training

Answer

Progressive high-impact and resistance training applies mechanical strain to bone through ground reaction forces and muscle pull, stimulating osteoblast activity most effectively.

Question 3

A cyclist presents with lateral knee pain that is worst during the downstroke at 30° of knee flexion. An Ober test is positive. What is the most likely diagnosis?

Accepted Answer

Iliotibial band syndrome

Answer

Iliotibial band syndrome classically presents with lateral knee pain at approximately 30° knee flexion (the impingement zone) and is confirmed by a positive Ober test indicating ITB tightness.

Question 4

Which joint position best isolates the inferior glenohumeral ligament during examination?

Accepted Answer

90° abduction with external rotation

Answer

The inferior glenohumeral ligament (IGHL) is the primary restraint to anterior translation with the arm at 90° abduction and external rotation, the position used in apprehension and relocation tests.

Question 5

A patient with rheumatoid arthritis presents to physical therapy. Which sign warrants immediate referral before cervical manipulation?

Accepted Answer

Upper extremity paresthesias with cervical flexion

Answer

Upper extremity paresthesias with cervical flexion suggest atlantoaxial instability (C1-C2 subluxation), a contraindication to cervical manipulation and requiring urgent referral.
