Focal Distonia of the hand in specific tasks

Focal hand dystonia is associated with repetitive motion and requires an accurate and timely differential diagnosis. In this sense, the main difficulty to make this diagnosis is the absence of indicators that make possible the precise characterization of this pathology, resulting in wrong diagnoses or wrong pathological associations. The question to solve then refers to establish if focal hand dystonia is the result of an abnormal sensory input that induces the generation of compensatory movements or antagonistic gestures executed unconsciously in order to alleviate symptoms. This research seeks to establish the parameters for a differentiated diagnosis with respect to carpal tunnel as well as to establish a protocol for the analysis of hand movements in specific tasks.
