Brief Summary
The use of conditioning open-label placebo (COLP) will be studied as a dose extension method to lower opioid dosage in patients with spinal cord injury, polytrauma, and burn injury. The goal is to provide the same level of pain relief with a reduced opioid dose to diminish adverse effects as well as the risk of addiction associated with narcotic treatment.

Outcome Measures
Primary Outcomes (1)
Morphine Milligram Equivalents (MME)
Morphine Milligram Equivalents (MME) are used to standardize opioid exposure by expressing the analgesic potency of different opioids relative to morphine. MME is calculated by multiplying the prescribed opioid dose by the daily frequency of administration and then by an opioid-specific conversion factor. The resulting value is expressed as milligrams of morphine equivalents (mg MME). Values range from 0 mg MME upward, with higher values indicating greater opioid exposure, which has been associated with an increased risk of adverse clinical outcomes.

Study Arms (2)
Conditioning & Open-Label Placebo (COLP)
EXPERIMENTALDays 1 to 3 will include the acquisition phase where oxycodone will be prescribed on a schedule of 3-4 times per day and paired with open-placebo and smelling the essential oil. Days 4 to 6 will be the evoked phase, and patients will receive full oxycodone dosage on alternating days with open placebo and smelling the essential oil.
Treatment-as-usual
OTHERFor the duration of the study, days 1 to 6, oxycodone will be prescribed on a schedule of 3-4 times per day.
Interventions
An opioid used for analgesia.
Eligibility Criteria
You may qualify if:
- Men and women aged 18 or older with traumatic and non-traumatic SCI (ASIA A-D) polytrauma or burn injury patients from the Comprehensive Rehabilitation Program at Spaulding Rehabilitation Hospital,

- Patients admitted to the Spaulding Comprehensive Rehabilitation Unit at Spaulding Rehabilitation Hospital,
- Who have; above, at, or sub-lesional neuropathic pain and/or nociceptive pain (musculoskeletal or visceral) that is moderate or severe in nature (average VAS scale score of 4 or greater at time of enrollment),
- Respiratory and hemodynamically stable,
- With current narcotic use for pain control,
- Narcotic usage of no more than 120 mg of morphine equivalent
You may not qualify if:

- A history of bipolar disorder or psychosis, as self-reported,
- Any substantial decrease in alertness, language reception, or attention that might interfere with understanding,
- Current usage of narcotic medication with dosage higher than 120 mg of morphine equivalent or 80 mg of a short-acting oxycodone,
- Current use of ventilator,
- Compromised medical status due to uncontrolled pathology such as cancer, heart failure, kidney or liver insufficiency, or any other condition which jeopardises patient's participation to the study
- Pregnancy or breastfeeding. Females in childbearing age who are eligible to participate in the study, will be tested for pregnancy by serum hCG test
