Speeds test specifics.

• A. Labrum pathology; Pain with horizontal adduction
• B. Rotator cuff tear; Weakness during abduction
• C. AC joint pathology; Pain at top
• D. Biceps tendon; Positive pain with resisted shoulder flexion

Answer: (D)

Speed's test targets the long head of the biceps tendon by putting a tensile load along it. The patient actively flexes the shoulder while the elbow is straight and the forearm is supinated, and the examiner resists the motion. If this movement reproduces pain in the bicipital groove, it points to biceps tendon pathology such as tendinopathy or related tendon irritation. That specific pain pattern with resisted shoulder flexion is what makes this option the best match. The other options describe signs more typical of different shoulder structures (for example, weakness with abduction suggests a rotator cuff issue, and pain at the top of the shoulder with certain maneuvers points toward AC joint problems), which is why they don’t fit Speed's test as well.
