The interobserver ICCs of the measurement of the distance between the posterior border of the acromion and the table at rest and during active shoulder retraction were greater than. 91 and. 88, respectively (table 3). For the measurement of the distance from the medial scapular border to the fourth thoracic spinous processes at rest and with active shoulder retraction, the ICCs were greater than. 50 and. 70, respectively. For positions 1, 2, and 3 of the LSST, the ICCs were greater than. 82,. 86, and. 70, respectively. Figure 5 shows the reliability data of the LSST position 2 (right side), and figure 6 shows the reliability data of the measurement of the distance between the posterior border of the acromion and the table (relaxed-left side). The Cronbach a coefficient for internal consistency of the different tests included in the assessment of scapular positioning was. 88 for both assessors.

All variables were normally distributed (Kolmogorov-Smirnov test, P>. 05; data not shown). A Pearson correlation analysis showed a significant association between pain severity (VAS) and the SDQ total scores (/=. 61, P<. 001). The results of Pearson correlation analysis searching for associations between the self-reported measures (VAS, SDQ) and the outcome of the tests for the assessment of scapular positioning (symptomatic side) are shown in table 4. Using the data of either assessor 1 or assessor 2, we found no associations (f>. 01). The comparison of the outcome of the 3 clinical tests between the symptomatic and asymptomatic sides is presented in tables 1 and 2. Comparing the symptomatic versus the asymptomatic side, assessor 1 found higher mean values in the symptomatic side for 4 of 7 test positions, and assessor 2 found higher mean values for 6 of 7 test positions. However, no statistically significant differences were observed between the painful and the nonpainful shoulders (P>. 01).

DISCUSSION
The interobserver reliability of the measurement of the distance from the medial scapular border to the fourth thoracic spinous processes with the shoulder relaxed was poor. However, it was shown that the interobserver reliability of the measurement of the distance between the posterior border of the acromion and the table at rest and during active shoulder retraction, the LSST, and the measurement of the distance from the medial scapular border to the fourth thoracic spinous processes with active shoulder retraction was fair. To our knowledge, this is the first study addressing the reliability of the measurement of the distance between the posterior border of the acromion and the table and the measurement of the distance from the medial scapular border to the fourth thoracic
