Sleep disturbances are an important component of the phenotypic profile of adult-onset idiopathic focal cervical dystonia (AOIFCD), reported in up to 70% of patients. Given the chronic nature of dystonia, greater understanding of potential sleep disturbances would require minimally intrusive monitoring and minimal input from the patients themselves.

The aims and objectives of this study were to

  1. To analyse sleep stages in detail amongst individuals diagnosed with AOIFCD using wrist-worn accelerometers and subjective PROs
  2. Evaluate concordance between subjective PROs and objective accelerometer measures
