title: Task specific focal hand dystonia: understanding the enigma and current concepts.
abstract: OBJECTIVE
  The first step in approaching task specific focal hand dystonia (TSFHD) is recognition that it is a neurological disorder and not a deficiency in practice or technique. To eliminate the enigma, TSFHD needs to be a more familiar entity. That is the objective of this paper.
  
  
  METHODS
  This is a state of the art review in concert with 3 decades of experience providing care for musicians written to act as a reference source. It is written as an introduction to TSFHD by reviewing history, etiology and current theories, presentation and characteristics, diagnosis and treatment.
  
  
  CONCLUSIONS
  Information sources, both web-based and by consultation need to be accessible, reliable and comprehensive. Accurate diagnosis should include the diagnosis of concurrent impairments and the confirmation that the diagnosis of TSFHD is correct. Successful treatment is likely to be interdisciplinary. Successful approaches may include the administration of botulinum toxin but approaches should not be restricted to pharmaceuticals. Instrument modification, altering technique and sensory motor retraining are potential adjunctive approaches. A dichotomy exists between the therapeutic benefit achieved with treatment and the musician's need for optimum hand function. The final goal is successful return to playing at a level that meets the musician's needs.
