Magic Bowl Virtual Reality Analgesia

Not Applicable

Completed

• Conditions: Pain Acute

• Registration Number: NCT07192822
• Lead Sponsor: University of Washington

Brief Summary

You will rate how much pain you experience during several brief thermal stimulations at painful but tolerable temperatures you pre-approve. During some of the stimuli you will be in virtual reality, and some you will not be in VR. Sometimes you will receive two brief stimuli at the same time.

Detailed Description

During VR, you will put your cyberhand into a bowl of animated water and will place virtual objects in the bowl and stir the virtual water. You will also receive several brief thermal heat stimulations at a temperature of your choice (sometimes one stimulus, sometimes two simultaneous stimuli). During some of the stimuli you will be in virtual reality, and some you will not be in VR.

Primary Outcome Measures

Name	Time	Method
worst pain during one stimulus vs during two simultaneous stimuli	measured immediately after each pain stimulus	graphic rating scale of worst pain intensity measured after one brief thermal pain stimuli, minimum = 0, maximum = 10, and measured again after two simultaenous thermal pain stimuli. In both cases, higher scores mean worse outcome

Secondary Outcome Measures

Name	Time	Method
worst pain during No VR vs worst pain during Virtual Reality	measured immediately after each pain stimulus	graphic rating scale of worst pain intensity measured after one brief thermal pain stimulus with no VR, minimum = 0, maximum = 10, and measured again after one thermal pain stimuli during virtual reality. In both cases, higher scores mean worse outcome
