Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Q: Abstract: Widespread use of the label "frozen shoulder" as a diagnosis for any stiff and painful shoulder condition has led to its becoming a rather meaningless, catchall term. In addition to confounding both the lay public and health care professionals, this indiscriminate labeling may prevent a patient from receiving appropriate treatment. In this article, I define frozen shoulder and review its pathologic and etiologic factors, epidemiology, natural history, and diagnosis. I present this information in correlation with an examination process to assist physical therapists in identifying suspected cases of frozen shoulder. I also present the current options for treatment, including physical therapy management with physical agents and exercise.
Which is the apt title for the abstract? option1: Frozen shoulder. option2: Large-needle thyroid biopsy: still necessary.
A:
Frozen shoulder.
