BACKGROUND In patients with focal hand dystonia, abnormal digit representations in the primary somatosensory cortex (S1) could be the result of enlarged and overlapping receptor fields, as suggested by an animal model of dystonia. A possible clinical correlate of this S1 abnormality is a disturbed spatial discrimination capability. OBJECTIVE To test the hypothesis that somatosensory spatial discrimination is abnormal in focal hand dystonia. METHODS Seventeen patients with focal hand… CONTINUE READING
