Which shoulder condition is characterized by stiffness, decreased range of motion, and a gradual return of ROM, often linked to diabetes and hypothyroidism?

• A. Resolved Quickly with Rest
• B. Shoulder Stiffness and Decreased ROM with Gradual Return of ROM due to Inflammation
• C. Acromioclavicular Joint Sprain
• D. Rotator Cuff Tear

Answer: (B)

The condition described is adhesive capsulitis, also known as frozen shoulder. It presents with a stiffness that limits range of motion, and the ROM often improves slowly over time. This pattern is classic when diabetes or thyroid disorders are present, as these systemic conditions increase the risk of capsular inflammation and eventual fibrosis of the glenohumeral joint. Mechanistically, the shoulder capsule becomes inflamed and thickened, leading to tightness that restricts movement in multiple directions. Early on, pain may be prominent, but the defining feature is the global ROM loss that gradually eases as the thawing phase sets in. Because the problem is tied to the capsule and its fibrotic changes rather than a focal ligament sprain or a rotator cuff tear, the limitation affects both active and passive movements and evolves over weeks to months. Other options don’t fit this pattern as well. A quick improvement with rest suggests a minor strain rather than frozen shoulder. An acromioclavicular joint sprain would show localized AC joint pain and point tenderness, not the diffuse, multi-plane ROM loss. A rotator cuff tear typically presents with weakness and pain particularly with lifting or overhead activities, and may not produce the same gradual, global improvement in ROM seen with adhesive capsulitis.
