Detailed Description
Visit 1-Remote: Consent. Random assignment: Subjects will complete informed consent and data collection of baseline information (demographics, medical history, perceptions of pain, and experiences with VR), surveys on pain, Pain interference, fatigue, and affect. The investigators will also help the participant upload the EMA technology onto their personal phone or tablet. Subjects will then be randomly assigned to receive either the 10- minute IVR session first or the 20-minute IVR session first. Visit 1 will take between 45 and 60 minutes.
Multiple Baseline EMA-Remote: Visit 2 will be scheduled 1-2 weeks later. During the time between visits the investigators will use ecological momentary assessment (EMA) technology to collect multiple measures of pain, fatigue and affect. In EMA subjects respond to prompts delivered through their cell phone or tablet ("pings") with documentation of current symptoms. It is a well-recognized method to capture immediate, synchronized experiences in subjects' natural environments. During this data collection period subjects will be "pinged" 3x daily and asked to rate their current levels of pain, fatigue, and affect. Time to complete these responses will be 15 minutes.
Visit 2-In person: pre Survey/Quantitative Sensory Testing (QST); First VR visit; post Survey/QST. The investigators will collect current pain, pain interference, fatigue and affect, and Quantitative Sensory Testing (QST). QST involves cutaneous (skin) psychophysical (semi-subjective) testing to assess sensory and pain perception pathways. QST quantifies the thresholds of detection of stimuli, the perceived intensity, and the temporal summation (changes in perception over multiple applications). These pain testing procedures are widely-accepted, non-invasive, and non-tissue damaging. The investigators will complete two types QST. Mechanical Pressure Pain Thresholds (MPPTh) will be assessed using a digital pressure algometer on the right upper trapezius and right thumb MP joint. Mechanical Temporal Summation of Pain (MTSP) will be assessed using weighted pinprick stimulators. The investigators will apply a train of 10 stimuli at the rate of 1 per second on the middle finger of the right hand, and subjects will rate the painfulness of the first, fifth, and tenth stimulus. All subjects will take part in two VR experiences (10 min and 20 min) for a total of 30-minutes in VR. After each experience subjects will rate their current pain, fatigue, and affect, and the investigators will complete QST. At the end of both sessions the subjects will rate their experiences of immersion using the Igroup Presence Questionaire, engagement using the Use Engagement Scale (UES), and simulation tolerance using the Simulator Sickness Questionnaire (SSQ). The investigators will also ask a series of open-ended questions about the participant's experiences with IVR and participation in the study. These will include questions about their enjoyment, perceptions of pain, and what they liked/did not like about the IVR experience as well as questions about the burden of being in the study. Visit 2 will take 1.5 to 2 hours
Post Visit 2 EMA-Remote: Subjects will complete three more days (72 hours) of 3x a day prompts for pain, fatigue and affect.
Visit 3-In person: pre Survey/Quantitative Sensory Testing (QST); Second VR visit; post Survey/QST
Post Visit 3 EMA-Remote: Subjects will complete 2 more days (48 hours) of 3x a day prompts for pain, fatigue and affect.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pain Numerical Rating Scale
Time Frame: Change in Pain Intensity from before to immediately after intervention
|
Pain Intensity - Numerical rating scale 0 to 10 with lower score better score
|
Change in Pain Intensity from before to immediately after intervention
|
Mechanical Pressure Pain Thresholds (MPPTh)
Time Frame: Median Pre and post intervention sensitivity to pressure scores in kilograms
|
Sensitivity to pressure will be assessed using a digital pressure algometer on the right upper trapezius and right thumb MP joint.
The measures from each site were averaged to obtain an overall mean pressure score for each participant.
A lower score indicates a better outcome.
|
Median Pre and post intervention sensitivity to pressure scores in kilograms
|
Mechanical Temporal Summation of Pain (MTSP)
Time Frame: Change in Sensitivity to pinprick from before to immediately after intervention
|
Sensitivity to pinprick was assessed using weighted pinprick stimulators.
We applied a train of 10 stimuli at the rate of 1 per second on the middle finger of the right hand, and subjects rated the painfulness of the first and tenth stimulus using a 1 to 100 pain intentsity rating scale.
We calculated the difference from the 1st stimuus to the 10th stimulus to calculate the sensitivity.
A lower change score is a better outcome
|
Change in Sensitivity to pinprick from before to immediately after intervention
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
PANAS
Time Frame: Change in affect form before immediately after intervention
|
Two scales one for Positive and one for Negative Affect - Score for each scale 10 to 50 with lower score indicating less of that affect
|
Change in affect form before immediately after intervention
|
PROMIS Fatigue
Time Frame: Change in fatigue from before to immediately after intervention
|
Fatigue on a scale of 0 to 28 with a lower score indicating less frequent experiences of fatigue
|
Change in fatigue from before to immediately after intervention
|
Other Outcome Measures

|
Impressions of Immersion into virtual reality experience.
12-Item Likert scale 1 (strongly disagree) to 5 (strongly agree).
