Screening of the cervical spine in subacromial shoulder pain: A systematic review.

Subacromial shoulder pain is a common clinical presentation with much diagnostic uncertainty. Some of this uncertainty relates to the involvement of the cervical spine as a source or contribution to subacromial shoulder pain. Currently, there is no accepted method of screening of the cervical spine in the presence of subacromial shoulder pain, which risks patients receiving misguided and/or ineffective interventions.
