Brief Summary
The use of the conditioning open-label placebo (COLP) paradigm 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 intake to diminish side effects as well as the risk of addiction associated with opioid treatment.

Study Arms (2)
Conditioning Open-Label Placebo
EXPERIMENTALDays 1 to 3 will include the acquisition phase where the opioid medication will be prescribed on a schedule of 3-4 times per day and paired with an open-label placebo. Day 4 and 6 will be the evoked phase, and patients will receive only the open-label placebo pill. On day 5 the opioid medication will be re-introduced as pharmacological reinforcement.
Treatment as usual
NO INTERVENTIONPatients in the standard of care group will receive their analgesic treatment through Spaulding Pharmacy as prescribed by their treating physicians. The treatment regime will include an opioid medication at the standard recommended dosage. Participants in this group will receive the treatment orally for 6 consecutive days.
Interventions
Sugar pill, with an essential-oil smell and of blue color used for conditioning.

- Patients admitted to the Spaulding Comprehensive Rehabilitation Unit at Spaulding Rehabilitation Hospital,
- Who have; above, at, or sub-lesional neuropathic pain and nociceptive pain (musculoskeletal or visceral) that is moderate or severe (average VAS scale score of 4 or greater at time of enrollment),
- Inpatients with polytrauma (defined as having injuries that affect two or more body systems or organs) or patients with burn injuries, amputations, or post-surgical (e.g., orthopedic surgery)
- 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:
