What is it about?
This was a prospective blinded study of consecutive patients with shoulder problems referred to the a tertiary care centre. The gold standard was arthroscopy or open surgery. To address the verification or workup bias, patients who did not undergo surgery during the study period were monitored for at least 2 years to verify whether the disease subsequently occurred.

Why is it important?
It is important to understand that provocation tests based solely on production of pain have limited value when used in isolation.
Perspectives
This article was one of my first articles on reliability and validity of clinical examination tests. As the years passed by and I learned more about clinical examination, I developed more appreciation for tests that are "not" based on pain and rather are affected by weakness. What causes pain is not as valid or reliable as the dysfunction of the muscles.
