musician's focal dystonia is defined as a contraction co-contraction or agonist / antagonist, involuntary spasm as maintained that generate disability or clumsy to play the instrument. The hand is the main impact of a higher percentage of guitarists, pianists followed, although they may result in perioral muscles of trumpet player, for example.
Linked to the repetition and training of musical activity.
Excess Hebbian network connections seems to be the problem, as explained in the blog Educating Neuroscience so fabulously. Motor neurons are activated and connected neurons to touch the skin and auditory neurons to hear, feel and interpret music. The increase in neuronal network connections causes a collapse in the function, for how prepared you are, as a surge.
the planum temporale is more developed in musicians. Planum temporale alterations are related to dyslexia. Playing an instrument is the best way to stimulate the brain, because it requires a strong neuronal activity. The brain of musicians is different but occupational focal dystonia is not exclusive to musicians. The highest incidence is found in the writer's cramp, and keepeth not influenced by any relationship with the music, simply by repeating a gesture intensive engine.
should be emphasized that no treatment has proven effective even in the musician's focal dystonia. A colleague gave entry to this subject a few months ago, in his blog .
Some authors attach importance to technical and All in the anomalous position with the instrument and the technique wrong and those responsible for the onset dystonic. Support the idea that their fingers are too stiff joints and muscle tension and when to play and should adopt a more relaxed in their hands and a good alignment head-trunk-arms. Include the rehabilitation of instrumental technique and posture in the prevention and treatment of musician's focal dystonia.
Some authors, such as Candia, proposed the immobilization of the affected fingers to reduce cortical representation.
Since sensory neurons create connections with motor neurons in the same region to increase the speed and effectiveness of technical movements, part of the treatment must go through these sensory neurons to return their condition, encourage Hebbian network change with tactile stimuli in that area, which have decreased, dicriminación two points, object recognition, texture ...
