FOCAL HAND DYSTONIA

FOCAL HAND DYSTONIA (FHD)

What is FHD?

A movement disorder characterized by involuntary muscle contractions and postures affecting extensively trained movements.

e.g. musician’s dystonia, writer’s cramp

How does it present?

  • Typical age: 30-40
  • Men & women can be affected
  • Painless
  • Absence of other signs & symptoms
  • Little variation each day
  • No sensory deficit
  • Loss of motor co-ordination in specific tasks only

How is it treated?

  • Specific, individualised retraining programmes
  • Repetitive sequential finger exercises
  • Relearning correct motor patterns
  • Slow tempo of writing/playing
  • Often involves splinting one or more fingers
  • Participant specific exercises- 2 hours per day
  • Can play own pieces, very slowly, if no FHD triggered

General points

  • 1st session is often just education, making a plan, write to GP/uni/orchestra
  • Consider a work cover plan
  • Must stop doing aggravating activity- may be 1-3 years
  • General exercises are important, e.g. physical fitness
  • Wellness behaviours, e.g. love of instrument, positive reinforcement
  • Understanding of longevity of treatment, realistic expectations- may not be 100% recovery
  • Try playing another instrument?

Summary

  • Often unknown cause or trigger
  • Must initially stop playing/writing
  • Treatment is lengthy & tedious for individual
  • Treatment & exercise programmes are often trial & error
  • Slow tempo of playing, repetition of correct motor patterns
  • Earlier presentation much better outcome than late
