Abstract
Introduction: Focal hand dystonia in musicians (MD) is a detrimental neuromuscular disorder that can end musical careers. It´s diverse pathophysiology challenges limited treatment options, and the optimal duration of protocols remains elusive. This study aimed to a) assess the effects of three days transcranial direct current stimulation (tDCS) and training on improvement of hand dexterity and b) reevaluate possible after effects 10 days post intervention. Methods: In this case-control study, participants underwent bihemispheric tDCS with bimanual mirrored finger movements of a CDEFG scale for 30 minutes. In contrast, Sham condition was also 30 minutes long but had only 30 seconds tDCS. Before (pretest) and after stimulation (posttest) participants performed motor tasks, which were used to evaluate temporal playing variability. All participants filled in Subjective rating scales of playing ability before and at the end of each intervention day. Videos were recorded at the same time points and assessed by 6 expert raters. Results: Temporal playing variability was analyzed in 16 pianists. Hand dexterity differed significantly between patients (n=8) and controls (n=8) across conditions. In patients, there were significant differences in temporal variability across conditions, but post hoc analysis (Bonferroni corrected) failed to show significant differences between conditions. Analysis of video and subjective ratings of 14 pianists (6 MD, 8 controls) revealed no significant changes in fine motor control. Conclusions: We did not find evidence supporting the notion that bihemispheric tDCS and training improve fine motor control in MD. Future studies will have to evaluate this with protocols with greater samples.
