A Pilot, Randomized Controlled Trial Evaluating the Effectiveness of Paraffin Wax On Burn Patient Function, Range of Motion and Scar

If the participants agree to take part in this study, the participants scars will be looked at and the investigators will select one site that will be involved in the research. The scar will be "randomized" to the paraffin wax or no paraffin wax groups. The treatment the participants get will be chosen by chance, like flipping a coin. Neither the participants nor the study doctor will choose what treatment you get. The participants will have a 50% chance of being given either paraffin wax or not.

The study will take place in an outpatient setting. The participants will not be admitted to the hospital overnight. All patients who enter the study will be required to follow-up for regular appointments with their burn department.

Before the participants begin treatment, the participants will come in for a pre-treatment visit where the investigators will collection information about the participants scars such as pictures, range of motion measurements, non-invasive probes, non-invasive imaging (Laser doppler imaging) and questionnaires. These questionnaires will be related to the symptoms, range of motion, function, and appearance of the participants' burn scars. At the pre-treatment visit, there is an also an optional blood draw where less than 2 tablespoons of blood are collected. It is estimated this visit will take less than 1 hour. The investigators will also collect information from the medical record about prior surgical and medical history.

Exercise treatments (which the participants have previously chosen to undergo in talking with the participants doctor) will occur approximately in 1-2-week intervals depending on what the Burn Center scheduling department allows. For completion of this study, the participants will undergo 4 exercise therapy sessions which may take about 8 weeks.

At each visit, the following measurements will be captured before and after each exercise session. Those assigned to the paraffin wax group will have an additional assessment collected before their exercise therapy session and after the paraffin wax has been removed. Measurements at each visit include active and passive range of motion measurements of the affected joint, non-invasive probe measurements to measure water loss and hardness of your scar and the adjacent area of normal skin, digital photography, non-invasive laser doppler imaging (LDI), surface-level skin temperature measurements using either an infrared thermometer or skin temperature strip as well as pain and itch rating scales.
