Abstract: BACKGROUND: Playing violin may lead to overload of the locomotor system. OBJECTIVE: The aim of this study was to assess body parameters for trunk symmetry in child violinists and compare with the control group. METHODS:We analyzed body posture of 101 children aged 7–12 years, mean age 11.09 ± 9.46, 49 child violinists and control group of 52 children. RESULTS: We found statistically significant differences for the difference in depth of the lower corners of scapulae and upper posterior spina iliaca, though greater asymmetries were found in the clinical control group. The remaining parameter values are close to significance, which may suggest that the process of postural change among the children had just started and that the existing asymmetries were easy to correct. We found positive correlation between body height and the difference in distance of the lower corners of scapulae from the spine: OL (p= 0.029, correlation coefficient value was 0.167) and the Thales triangle height: (p= 0.018, correlation coefficient was 0.214). CONCLUSIONS: Position maintained while playing the violin changed some parameters characterizing the curvature of the spine in frontal plane. We found the importance of detailed analysis of children body posture and its critical assessment.
