NCT07837687

Brief Summary

Limited studies have objectively evaluated the benefit on skin pliability, and relieving itch and pain of paraffin wax, nor has paraffin wax treatment been compared to mineral oil, which is an ingredient in therapeutic paraffin wax. The objective of this study is to examine the immediate impact after paraffin treatment compared with mineral oil controls on joint passive range of motion.

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Adult burn survivors (16 years and older)
  • Have joint contractures ≥15% normal PROM at two different joints directly related to their burn injury/scars
  • Are proficient in English and/or French
  • Provide informed consent

You may not qualify if:

  • Patients who have a cognitive/psychiatric condition that could impair their understanding of the consent process or adherence to protocol procedures
  • Patients with neurological impairments related to their burn injury, such as a drop foot or a drop wrist
  • Patients with pre-burn joint pathology that limited their PROM
