Neural Mechanisms of Immersive Virtual Reality in Chronic Pain
Sponsor: University of Maryland, Baltimore
Summary
This project examines, in chronic pain, the mechanisms of immersive virtual reality compared to the mechanisms of placebo hypoalgesia. The potential of developing new non-pharmacological premises for low-risk interventions for pain management is high.

Interventions
Active Virtual Reality
Participants will be assigned to an immersive VR environment.
sham Virtual Reality
Participants will be assigned to a sham VR environment without the immersive experience.
No Intervention
Participants will experience tonic pain tolerance tests without exposure to any environments.
Naloxone
4mg of Naloxone will be administered (0.1 mL of 40 mg/ml naloxone solution given intranasally). A random allocation sequence will be independently generated by the UM Pharmacy. The Principal investigator will call for each experiment.
Saline
Intranasal Normal Saline (0.1 mL 0.9% sodium chloride) will be administered shortly before beginning the fMRI experiment. A random allocation sequence will be independently generated by the UM Pharmacy. The Principal investigator will call for each experiment.
Natural history
Participants will not be provided Naloxone or Saline.
