Investigation of parameters' affecting the performing posture in string musicians with video analysis method

In this study, the relationship between the parameters' expected to affect ergonomic risk level of performing posture evaluated in adult strings musicians with video analysis method. 15 musicians who played violin or viola between 18-53 years were included in the study group. The ergonomic risk level of participants' music performing posture during the performance measured by video analysis and musculoskeletal complaints, music performance anxiety level, physical activity level, joint hypermobility, dominant hand preferences were evaluated. As a result of the study, there was a significant positive relation between end of performances of ergonomic risk level of right upper extremities music performing postures on musculoskeletal complaints in the back region (p=0.029), time-dependent changes of the ergonomic risk level of left upper extremities music performing postures and musculoskeletal complaints in the hand/wrist area (p=0,04), mid-performances of the ergonomic risk level of left upper extremities music performing postures and trunk flexion hyper-mobility level (p=0.026). The beginning (p=0,04) and end of perfomances' (p=0,001) of the ergonomic risk level of left upper extremities music performing posture was high in musicians with graduate and post-doctorate education level, but the risk level was low in musicians with postgraduate education level (p=0,01). There was no significant relationship between the ergonomic risk level of performing posture, physical activity, anxiety and hand preferences (p>0.05). As a result of this study, it was found that the performing postures of string musicians' have a high level of ergonomic risk and there are many parameters that affect the performance postures in violin and viola musicians. The present study will guide the professionals to evaluate musicians according to the symptoms that need attention in a holistic way to create protective approaches from a multidisciplinary perspective.
