Objective: 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.
Methods: 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.
Results: 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).
Conclusion: 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.
