An interventional study of Paraffin wax and Mineral oil in Burn Joints and Joint Contractures, sponsored by Centre hospitalier de l'Université de Montréal (CHUM). Not yet recruiting. Open to participants aged 16 Years and older. Per ClinicalTrials.gov, last updated 2026-09-28.
Sponsored by Centre hospitalier de l'Université de Montréal (CHUM) · Not applicable, Interventional, and Treatment
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.
The development of joint contractures after a burn injury represents one of the most important morbidities leading to reduced function and quality of life. Paraffin wax is commonly applied to contracted joints for its proposed benefits of increasing skin pliability, and/or relieving itch and pain. This pilot study will determine the feasibility of performing a fully powered study to objectively evaluate whether paraffin wax therapy significantly improves PROM in adult burn survivors with joint contractures of greater than 15% normal joint ROM (upper or lower extremity) compared to equivalent mineral oil treated joint contractures. This study will characterize the changes in PROM, AROM, itch, and pain in adult burn survivors immediately after the application of paraffin wax treatment relative to an intra-individual control scar treated with mineral oil. This will be a prospective, evaluator-blinded, intra-individual, randomized, controlled, pre-post pilot study.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Start is estimated for Oct 2026; primary completion for Oct 2028, 24 months later.
Of 210 non-industry interventional studies with no phase under Burns, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 38. This study's planned 24 months is above that.
Counting every sponsor, half of 239 studies reached it within 15 months; a quarter within 6 and three quarters within 38.
