What special test can help diagnose frozen shoulder or adhesive capsulitis?

Apley's Scratch Test is a valuable clinical tool used to assess shoulder mobility and function. In the case of frozen shoulder or adhesive capsulitis, this test helps evaluate the range of motion and any restrictions in the shoulder joint. It involves the patient attempting to touch their opposite shoulder blade by reaching over the shoulder and behind the back, assessing both internal and external rotation.

Frozen shoulder is characterized by stiffness and limited range of motion, so patients often struggle with this test due to the adhesive nature of the capsular restrictions. Apley's Scratch Test effectively highlights the functional limitations faced by those with adhesive capsulitis, making it a key assessment measure for diagnosing this condition.

The other tests mentioned, such as Yergason's Test, Speed's Test, and AF-ROM Test, serve different purposes and are not specifically utilized to diagnose frozen shoulder, as they focus on other shoulder pathologies or aspects of shoulder function.
