Introduction:Abnormal
scapular movements and position is related to shoulder dysfunctions. Lateral
scapular slide test is used to determine scapular position in coronal plane
however, different studies have shown conflicting results for the reliability
of the test in position of 90 degrees of abduction. According to the more functionality of
scaption compare to the abduction as well as scaption is a familiar task for
athletes, in current study, 90 degrees of scaption was used instead of 90
degrees of abduction and then the
reliability of modified lateral scapular slide test (MLSST) was evaluated. Materials
and Methods: Fifteen healthy overhead
sport-men, aged 20 to 40, were recruited in the study. The minimal vertical
distance between inferior angle of scapula and spinous process of T7 was
measured by two examiners in one session and by one examiner in the next week
using a caliper in neutral position (arm is relaxed at the side), 90 degrees of
scaption and 180 degrees of elevation. Results: Reliability
in neutral position was maximum (ICC 0.83 to 0.97, good to high). In 90 degrees
of scaption, inter-rater and intra-rater reliability were 0.70 to 0.75 and 0.65
to 0.83, respectively. In 180 degrees of elevation, inter-rater reliability was
0.58 and intra-rater reliability was 0.84 to 0.89. Conclusion: 90 degrees of Scaption and 180 degrees of
elevation, as a functional position in the athletes, may be used as choice
positions in lateral scapular slide test
