ABSTRACT
Even though the scapular asymmetry is common in asymptomatic individuals, it is essential to identify the normal degree of scapular variation. This helps in differentiating normal variation from pathological positional abnormality of scapula and hence useful in detecting clinical abnormality. Kibler WB assumed that a difference of less than or equal to 1.5cm is the normal variation, but the scientific evidence is limited. Therefore, the aim of the present work is to find out the normal scapular asymmetry in asymptomatic young males aged 18 to 25 years using Kibler’s Lateral Scapular Slide Test (LSST). Study design is descriptive. 150 asymptomatic males aged 18 to 25 years were the chosen population. Scapular position was evaluated using LSST in three shoulder positions Viz shoulder at neutral, shoulder at 450 and shoulder at 900. The mean scapular asymmetry was .570 ± .615, .563 ± .562 and .626 ± .515 when shoulder at neutral, shoulder at 450 and shoulder at 900 respectively. The difference between two sides was statistically significant in all the three positions. But, between the three positions the difference was statistically insignificant, inferred that scapular asymmetry was more or less same in all the three positions. It is concluded that the scapular distance was significantly higher in dominant side. The asymmetry observed in the present study is comparatively lower than assumed cut off values and hence the present findings anticipate clinical usefulness in early diagnosis of shoulder and scapular problems of young males.
