Preliminary Normative Data on the Position of the Scapula in Normal Six-Year-Old Boys

Abstract

This study established preliminary normative data on the position of the scapula on the thorax in 91 normal 6-year-old hoys. Scapular abduction and upward tilt of the scapula were measured with a ruler and a beveled prOTRactor in four test positions. The data showed that multiple measurements were needed due to the high variability of scapular positioning across subjects. The most reliable and least variable of the four test positions was the quadruped position. Results provide therapists with acceptable guidelines for the range of scapular deviation in normal 6-year-old boys. Implications for further research are discussed.
