Brief summary
The effect of Virtual Reality on pain and memory.
Detailed description
The primary outcome measure was the participants' accuracy of remembering the pattern of a total of five pain stimuli per set. Using the Quantitative Sensory Testing method of limits, each participant selected a temperature they found painful but tolerable that they were willing to receive several more times, later in the study. They then received a sequence of five brief stimuli to their wrist, with a brief inter-stimulus interval between each stimulus.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain Memory Recall Test | After each brief pain stimulus set, participants performed a brief distractor task before completing the Pain Memory Recall Test. The Pain Memory Recall Test was completed within 5 minutes after each brief thermal stimulus set. | After each brief thermal stimulus set, participants were asked to recall the exact pattern of the most recent sequence of 5 brief thermal stimuli, recalled in exact order, via our five question pain memory recall test (min = 0%, max -= 100% correct). Lower % correct scores mean less accurate memory (poorer outcome). |
| Participants subjective rating of the accuracy of their memory for painful stimuli | measured within 10 minutes after each pain stimulus set | Using a graphic rating scale, on a scale from zero (min) to 10 (max), participants rated how accurately they could remember their pain during No Virtual Reality vs during Virtual Reality. Higher scores indicated higher accuracy and more positive outcome. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Presence ratings using Graphic Rating Scales | measured within 10 minutes after participant was in virtual reality | Participants rated their illusion of being there in the computer generated world, as if it was a place they were visiting, on a scale from zero to 10, where zero = none at all and 10 = completely there. |
