Dystonia is defined as an involuntary contraction of the agonistic and antagonistic muscles, which can lead to repetitive involuntary movements and/or abnormal positions. The affected population includes individuals who require repetitive movements on their regular daily life; one of the most affected populations are the musicians and professional writers [1]. In the European and American population Focal dystonia varies its prevalence between 3 and 29.5 per 100.000 inhabitants [1][2]. Inside musicians dystonia it is estimated that of all musicans, 0.5 % to 1% suffer from some form of focal dystonia [1][3]
