I. ABSTRACT

Focal hand dystonia (FHd) is a disabling movement disorder of unknown etiology

that can develop in productive, motivated individuals who perform highly repetitive,

intensive hand tasks. This chapter summarizes our research supporting aberrant

learning as one origin of FHd. Our studies document degradation of the somatosensory representation of the hand in animals and patients with dystonic hand movements as characterized by large receptive fields (rfs), overlapped across adjacent

digits and glabrous-dorsal surfaces, persistence of digital receptive fields across

broad cortical distances, high ratio of amplitude to latency in somatosensory evoked

field responses, and decreased spread and abnormal sequencing of digit representa-
