String played and bow stroke had the greatest effect on joint kinematics. The string played had the greatest impact on shoulder kinematics, and the bow stroke had the greatest impact on elbow and wrist kinematics. Based on these results, we propose guidelines for future research designed to study bow kinematics in the field of biomechanics of violin movements.

The pathophysiology is not fully understood, and while the available treatment strategies can help with improving motor control, they are rarely able to fully and reliably rehabilitate playing skills. Recent studies suggest that apart from genetic factors, maladaptive neuroplasticity, and the repetitive nature of the instrumental technique, psychosocial, psychological, and behavioural factors might also play a role in the onset of MFD. However, the presence of some of these risk factors is supported primarily by anecdotal evidence, with only a few aspects examined empirically. To explore this area further, 14 semi-structured interviews were conducted with a convenience sample of practitioners (8 medical professionals and 6 musician-coaches) who frequently treated MFD sufferers. Throughout their career, these participants are estimated to have interacted with more than 2,000 musicians with MFD, creating a large, indirect sample. A detailed patient profile emerged from the data with three main components: 1) the negative impact of social environments, including traumatic experiences and low quality of instrumental teaching; 2) a perfectionist, anxious, overly sensitive, and acquiescent personality type; and 3) obsessive, controlling, and inadequate practice behaviours. Participants stated MFD needs to be treated holistically and that neglecting these aspects during treatment could jeopardise rehabilitation.
