Playing an instrument often requires a certain posture and asymmetric position that may affect the anteroposterior spinal curvatures and may lead to postural asymmetry. The aim of the study was to evaluate the spinal curvatures in the sagittal plane and the magnitude of asymmetries in the trunk in the frontal plane in a group of music students in comparison with a control group.
The group of 67 students aged 20 to 26 years was made up of 2 subgroups: the musicians (violin playing students of the Academy of Music in Wroclaw) and the control group (physical therapy students who played no instruments). The examination included an interview, measuring of somatic characteristics, and evaluation of body posture by means of the photogrammetric method.
The spinal curvatures of the instrumentalists in the sagittal plane differ from the control group mainly in terms of length and depth parameters. Compared with the control group, the musicians were characterized by statistically more significantly longer and deeper thoracic kyphosis (P < .01) and more shallow lumbar lordosis (P < .05), a greater angle of thoracic kyphosis (P < .005), and a smaller inclination angle of the thoracolumbar and lumbosacral section of the spine (P < .01).
In the group of musicians, the asymmetries in the area of shoulders and waist triangles as well as the distance of the spinous processes from the C7 to S1 line were more frequent.
演奏乐器通常需要特定的姿势和不对称的体位，这可能会影响脊柱的前后曲度，并可能导致姿势不对称。本研究的目的是评估一组音乐专业学生与对照组相比，其矢状面脊柱曲度以及额状面躯干不对称的程度。
67名年龄在20至26岁之间的学生组成的研究对象分为两个亚组：音乐家组（弗罗茨瓦夫音乐学院的小提琴演奏专业学生）和对照组（不演奏乐器的物理治疗专业学生）。检查包括访谈、身体特征测量以及通过摄影测量法评估身体姿势。
乐器演奏者矢状面的脊柱曲度与对照组的差异主要体现在长度和深度参数方面。与对照组相比，音乐家组的特征为胸段后凸在统计学上更显著地更长、更深（P <.01），腰段前凸更浅（P <.05），胸段后凸角度更大（P <.005），以及脊柱胸腰段和腰骶段的倾斜角度更小（P <.01）。
在音乐家组中，肩部和腰部三角区域的不对称以及棘突与C7至S1线的距离更为常见。
