Changes in brain anatomy in focal hand dystonia
Annals of Neurology, 2004AbstractNo consistent cerebral anatomical abnormality has ever been reported in primary focal hand dystonia (FHD). The present voxel‐based morphometry study showed a significant bilateral increase in gray matter in the hand representation area of primary somatosensory and, to a lesser extent, primary motor cortices in 36 patients with unilateral FHD ...

To examine whether the corticospinal system emanating from the primary motor cortex may be organized to facilitate generation of dystonic movements.In this cross-sectional observational study, finger movement (FM) representations were assessed in 10 patients with focal hand dystonia (FHD) and 10 matched healthy controls by transcranial magnetic ...

Sensory training for patients with focal hand dystonia
Annals of Neurology, 2002AbstractSome patients with focal hand dystonia have impaired sensory perception. Abnormal sensory processing may lead to problems with fine motor control. For patients with focal hand dystonia who demonstrate sensory dysfunction, sensory training may reverse sensory impairment and dystonic symptoms.

Focal hand dystonia (FHD) often presents as a task-specific disorder, but may generalize to other tasks or even become spontaneous. The difficulty for therapy is to relieve the dystonia, but not impair the ability of the hand for skillful movement. A variety of therapeutic approaches can be considered, but the most commonly used effective therapy is ...

Strength deficits in primary focal hand dystonia
Movement Disorders, 2005AbstractCortical activation is reduced when patients with focal dystonia perform movements that do not induce dystonic posturing. This finding suggests that the cortical drive to muscles may in some circumstances actually be reduced not increased, as suggested by basal ganglia models of dystonia as a hyperkinetic disorder. The purpose of this study was

Spatial discrimination is abnormal in focal hand dystonia
Neurology, 2000In 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.To test the hypothesis that ...

The neurophysiology of focal hand dystonia in musicians
2006Abstract This chapter discusses the neurophysiology of focal hand dystonia in musicians. Studies of focal hand dystonia reveal abnormalities in three main areas: (1) reduced excitability of inhibitory connections at all levels (spinal, brainstem, and cortical) of the motor system; (2) reduced sensory perception and integration; and (3 ...

Botulinum toxin treatment of occupational and focal hand dystonia
Movement Disorders, 2004Botulinum toxin is now the first-line therapy for writer's cramp and other occupational dystonias, with well-established efficacy and safety. Future studies will allow us to understand better the physiological effects of injection and to refine and enhance our treatment of focal hand dystonia.

Is focal hand dystonia associated with psychopathology?
Movement Disorders, 1991AbstractThe purpose of this study was to determine if patients with focal hand dystonia have any significant psychopathology. We studied 20 patients with hand cramps who were participating in a therapeutic trial of botulinum toxin injectins. Patients were interviewed and administered the Minnesota Multiphasic Personality Inventory (MMPI), Beck ...
