  • People who have a muscle stiffness score of 2 or higher (on a standard medical scale called the Modified Ashworth Scale) in the specific muscle group being treated
  • People whose arm muscles are eligible to receive the full recommended dose of the study drug (1000 units of Dysport) (confirm with trial site)

  • Male participants who agree to use effective contraception during the study if their partner could become pregnant

Who may not be able to join:

  • People with any medical condition — including severe swallowing difficulties or breathing problems — that the trial doctor believes could increase the risk of side effects from Botulinum toxin treatment
  • People with a known disease affecting the connection between nerves and muscles, such as myasthenia gravis, Lambert-Eaton syndrome, or ALS (motor neurone disease)

  • People currently taking certain medications that affect how nerves and muscles communicate (such as certain antibiotics or muscle-blocking agents) within 30 days before the study start
  • People taking other medications that the trial doctor believes would interfere with assessing the safety or effectiveness of the study treatment, including certain blood-thinning medicines (people on vitamin K antagonists may be considered if their blood levels are within a specific controlled range)
  • People who have had or are planning tendon lengthening surgery, or who have significant joint stiffness or muscle wasting at the treatment site, in the 6 months before screening
  • People who have used an experimental drug or medical device within a specified recent period before the study start, or who plan to do so during the study (confirm with trial site)
