Virtual Reality Therapy
Drug: Low-dose pain medication (Ketalar) and saline placebo

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Crossover Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Supportive Care
Official Title: Modifying Virtual Reality Analgesia With Low-Dose Pain Medication

Further study details as provided by University of Washington:

Primary Outcome Measures:
  • Pain responses between placebo and the low-dose pain medication while playing Snow World. We will assess pain responses with subjective questionnaires concerning the participant's experience while playing Snow World. [ Time Frame: Conclusion of 120 study visits. Each participant will spend a total of 8 hours with us. ] [ Designated as safety issue: No ]

Estimated Enrollment: 60
Study Start Date: April 2013
Estimated Study Completion Date: June 2014
Estimated Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Low-dose pain medication
80min IV infusion of a low-dose pain medication
Drug: Low-dose pain medication (Ketalar) and saline placebo
Placebo Comparator: saline placebo
80min IV infusion of a saline placebo
Drug: Low-dose pain medication (Ketalar) and saline placebo

Detailed Description:

This is a randomized, double-blind, placebo-controlled, within subject 2x2 factorial, repeated measures study. Research participants will play two versions of the Virtual Reality based video game "Snow World" and be given thermal and electrical stimulus. Each of two study visits will be identical with the exception of whether or not the participant will receive an iv infusion of a low dose pain medication or a saline placebo.
