First of all, its necessary to make a distinction about the term “Dystonic Syndrome” whose definition coincides with “ Task Specific Focal Dystonia” in everything but the but the cause, that is why the author prefer the term “Dystonic Syndrome” denomination.
The manifestation or external apparatus is characterized by a motor activity that challenges the voluntary motor control of the musician, like trembling, spasms, contractions, which involves muscular groups that are active while peforming with the instrument preventing them to be used for playing. In numerous occasions, this muscular chaos extrapolates or moves to other daily activities that involve the same muscles. In some cases even some muscles not related with the performing experiment tension.
The inner manifestation, not visible part of the disorder, is associated to terms such as anxiety, despair, worry, insecurity, vulnerability, all of them, different modalities of fear that shape the disorder in most of the cases.
When the patient wants to carry out a movement related to a specific task (movement that tends to be repetitive), experiments an involuntary tension that makes it absurd.
There is very scarce or non-research about the origin of tension as the triggering fact of the disorder, hence we can see several definitions in Internet claiming that we are in front of a neurological disorder. However, according to the same articles, causes are not clear or uncertain, noneless they stick stubbornly to “it is a neurological disorder”.
We realize that “Task Specific Focal Dystonia” is a very controversial issue; some people believe in the neurological origin of the tension, some people believe in the emotional origin of it. We see recoveries day by day based on therapies that have nothing to do with the intake of medication, or other type of neurological treatment, which at least cast serious doubts on the overall reliability of the neurological presumptions.
