Exclusion Criteria:

  • Allergy/hypersensitivity to Dysport® or any of its components.
  • Pregnancy.
  • Women who breastfeed their children.
  • Treatment with Botulinum toxin-A within the last five months.
  • If there has been dose changes in any muscle-tone altering medication within two weeks of Visit 1.
  • A clear degenerative cause behind the pain as elucidated by the clinical examination (e.g. history of osteoarthritis).
  • Intellectual disability and/or communication impairment that disable the individual from answering the questionnaires and giving informed consent.
