Marker-Based Method for Analyzing the Three-Dimensional Upper Body Kinematics of Violinists: Reproducibility.

Background: Recently, Wolf et al. proposed a novel, marker-based method to analyze the three-dimensional upper-body kinematics of high string players for clinical application. The method provides an objective evaluation of high string players' motor strategies, especially in the shoulder complex, by distinguishing between the scapulothoracic (ST) and glenohumeral (GH) joints, while minimizing skin movement artifacts, marker occlusions, and limitations due to instrument placement.

Marker-Based Method for Analyzing the Three-Dimensional Upper Body Kinematics of Violinists and Violists: Development and Clinical Feasibility.

Aims: High string players (violin and viola) often suffer from musculoskeletal disorders. Although 3D motion analysis has proved helpful in diagnosing different musculoskeletal syndromes and identifying injurious movement patterns in violin and viola performance, more detailed analyses of upper body movement strategies and especially of the shoulder complex have not yet been recorded. The use of spherical surface markers on some anatomical landmarks is, however, inappropriate when an instrument is being played.
