Abstract

The purpose of this study was to investigate the most effective and comprehensible method for the assessment of resting scapular position (RSP) and pain level (PL) in unilateral shoulder pain (USP). Fifty volunteers with USP were involved in the study. Resting scapular assessments of the patients' pain sides (PS) and non-pain sides (NPS) were evaluated. The assessment tools for RSP are: 1) sternal notch (SN) to coracoid process (CP) distance 2) 3rd thoracic spinous process (T3S) to posterolateral angle of acromion (PLA) distance 3) scapular index 4) 8th thoracic spinous process (T8S) to inferior angle of scapular (IAS) distance 5) supine measurement of pectoralis minor (PM) distance 6) standing PM distance 7) PM index (PMI) and 8) PM pain. The paired t-test was used to compare PS and NPS in RSP. Pearson correlation analysis was used to confer a relationship between the PL and RSP. The results of this study indicated that: 1) all the variables between the PS and NPS for RSP were statistically significant(p<.05) and 2) the PMI showed the strongest relationship in the correlation analysis between RSP and PL(p<.05, r=.37). Therefore, it can be concluded that there is a relationship between PMI and PL and it is suggested that an assessment tool using PMI to diagnose shoulder pain would be clinically effective.
