In many instances , no or minimal attempts to screen were undertaken or reported .
Background 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 .
Objective To evaluate approaches used to screen the cervical spine in patients with subacromial shoulder pain .
Subacromial impingement syndrome: the effect of changing posture on shoulder range of movement.
STUDY DESIGN R and om allocation of subjects into a placebo-controlled , crossover study . OBJECTIVES To investigate the effect of changing thoracic and scapular posture on shoulder flexion and scapular plane abduction range of motion in asymptomatic subjects , and in subjects with subacromial impingement syndrome . BACKGROUND Changes in upper body posture and concomitant imbalance of the muscle system have been proposed as one of the etiological mechanisms leading to subacromial impingement syndrome . Although clinicians commonly assess posture and devise rehabilitation programs to correct posture , there is little evidence to support this practice . METHODS AND MATERIAL S Selected postural , range of movement , and pain measurements were investigated in 60 asymptomatic subjects and 60 subjects with subacromial impingement syndrome , prior to and following thoracic and scapular taping intended to change their posture .  RESULTS Changing posture had an effect on all components of posture measured ( P<.001 ) and these changes were associated with a significant increase ( P<.001 ) in the range of motion in shoulder flexion and abduction in the plane of the scapula . Changing posture was not found to have a significant effect on the intensity of pain experienced by the symptomatic subjects , although the point in the range of shoulder elevation at which they experienced their pain was significantly higher ( P<.001 ) . CONCLUSIONS The findings of this investigation suggest that changing 1 or more of the components of posture may have a positive effect on shoulder range of movement and the point at which pain is experienced
