Abstract

Background. The purpose of our research was to evaluate the connection between the pelvis in sitting position and posture in standing position, as well as the manner of changing from supine position to sitting position. Material and methods. We examined 37 six-year-old boys and girls. Posture was assessed according to Hoppe’s modified scale of posture measurement. The manner of maintaining upright sitting position and changing from supine position to sitting position was also examined. The angle of pelvic back tilt in sitting position was examined by means a Rippstein plurimeter. Statistical analysis was based on the Spearman test, the Manova-Anova test, and the Tukey test, taking p < 0.05 as the critical level. Results. There is a clear connection between the way a young child maintains sitting position and both pelvic back tilt and the quality of posture (in both cases r = 0.67, p < 0.001). We also found a smaller but equally important connection between the way of changing from supine to upright sitting position (r = 0,44 p < 0,01) and the other parameters. Conclusions. The evaluation of pelvic control in sitting position and in the course of sitting up is a good technique for the diagnosis of postural tone in young children.
