Enrollment: 40
Study Start Date: April 2012
Study Completion Date: April 2013
Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: botulinum toxin A Drug: Botulinum toxin type A

Detailed Description:
Neuropathic pain remains a significant cause of life quality deterioration. This study includes spinal cord injury patients with refractory chronic neuropathic pain and investigates whether injection with botulinum toxin A improves pain scores.

Ages Eligible for Study:   20 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • more than twenty years of age
  • paraplegic or tetraplegic due to cervical and thoracic spinal cord injury
  • more than 12 months since spinal cord injury and ASIA impairment scale unchanged for more than 6 months
  • persistence of neuropathic pain for more than three months or remission and recurrence of neuropathic pain for more than six months
  • a pain score of 40mm or more on the visual analogue scale

Exclusion Criteria:

  • neuropathic pain caused by confounding factors other than spinal cord injury
  • contraindicated for botulinum toxin type A
  • a change in pain medication one month prior to study enrollment
  • a condition involving neuromuscular junction (Ex. Eaton Lambert disease, myasthenia gravis)
  • person who received botulinum toxin type A within three months prior to study enrollment
