About this study

Official title: Theory to Application: Workflow Feasibility of Virtual Reality Sedation in a VA Pain Clinic

The goal of this clinical trial is to learn whether virtual reality (VR) can be added to routine knee injection appointments at a VA outpatient pain clinic without slowing down or disrupting clinic operations. The study will enroll 45 adult veterans who are scheduled for a knee injection at the Atlanta VA Arcadia pain clinic.

The main questions it aims to answer are

Read more
  • Can a VR headset be set up and used during a knee injection with minimal time disruptions?
  • How many patients agree to take part, how many need to stop using the headset early, and how satisfied are patients and clinicians with the experience?

Researchers will compare patients who wear a VR headset during their injection to patients who receive the usual injection without VR. This will show whether VR may change anxiety, time spent thinking about pain, satisfaction, and memory of the procedure.

Participants will:

  • Be assigned by chance to one of two groups. Two out of every three participants will use VR, and one out of every three will receive usual care only.
  • If in the VR group, wear a headset showing a virtual environment with little motion. A research team member will place the headset before the needle goes in and remove it after the injection is finished.
  • Receive their scheduled knee injection as usual from their clinician.
  • Complete a short survey right after the procedure.

Taking part happens during one clinic visit and takes about 30 minutes. The knee injection itself is standard care and is not changed by the study.

Read the detailed description

Background: Intra-articular knee injections are among the most common outpatient procedures for managing chronic knee pain, including knee osteoarthritis, a condition that disproportionately affects veterans. These procedures are often associated with periprocedural pain and anxiety, which are commonly managed with pharmacologic options such as opioids or benzodiazepines that carry risks including respiratory depression and dependence. Immersive VR is a non-pharmacologic approach with a growing evidence base for reducing procedural pain across many clinical settings. However, no published studies have evaluated VR during knee injections, and little is known about how VR can be integrated into the operational demands of a busy outpatient pain clinic.

Design: This is a single-site, two-arm, parallel-group, open-label randomized pilot feasibility trial at the Atlanta VA Healthcare System Arcadia outpatient pain clinic. Following informed consent, participants are randomized 2:1 to VR plus standard of care or standard of care alone using sequentially numbered, sealed, opaque envelopes prepared in advance. No stratification is used. The 2:1 allocation was chosen to maximize VR exposure and safety data.

Intervention: In the VR arm, a trained research team member places a commercially available immersive VR headset (SustainVR) after consent and patient positioning but before needle insertion, and provides a brief orientation to the device. The headset remains on through needle insertion and the full injection and is removed after needle withdrawal. SustainVR is a consumer wellness device used here as a non-pharmacologic adjunct, not a replacement for any part of standard care. All injections and medications are delivered per standard clinical practice.

Feasibility benchmarks: Feasibility will be defined a priori as an enrollment rate of at least 60%, a VR discontinuation rate below 10%, VR setup adding 5 minutes or less to total procedure duration, and willingness to use VR again reported by at least 60% of VR arm participants.

Analysis: Feasibility and workflow outcomes will be summarized descriptively. Patient- and provider-reported comparisons between arms are exploratory and intended to estimate effect sizes and variability for a future fully powered trial.

Safety: VR-related adverse events are monitored in real time by the research coordinator and treating physician. The study will be paused for review if VR-related adverse events occur in more than 20% of VR arm participants.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Immersive Virtual RealityDevice

    Also called SustainVR, VR

    Commercially available, non-invasive, head-mounted immersive virtual reality system used as a non-pharmacologic distraction adjunct during a standard of care intra-articular knee injection. The virtual environment contains low levels of motion to reduce the risk of cybersickness. A trained research team member places the headset after patient positioning and before needle insertion, provides a brief orientation, and removes it after needle withdrawal. Delivered once, during a single clinic visit. The device does not replace any component of standard clinical care.

Study groups in NCT07884851
Study groupRoleWhat they receive
Standard of CareNo interventionParticipants receive their scheduled intra-articular knee injection per standard clinical practice with no additional intervention. Participants complete a post-procedure survey, and the treating provider completes a provider survey.
VR Plus Standard of CareExperimentalParticipants receive their scheduled intra-articular knee injection per standard clinical practice, with the addition of an immersive virtual reality headset (SustainVR). After consent and patient positioning, a trained research team member places the headset and provides a brief orientation to the device and virtual environment. The headset remains on before and throughout needle insertion and the full injection and is removed after needle withdrawal. The headset is removed immediately if the participant requests it, if an adverse reaction is observed, or if the treating physician determines it interferes with the procedure. Participants complete a post-procedure survey, and the treating provider completes a provider survey.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Enrollment Rate

    Proportion of eligible patients approached who provide written informed consent, calculated as the number consented divided by the number eligible and approached. Pre-specified feasibility benchmark: enrollment rate of 60% or greater.

    Measured: Throughout the enrollment period (approximately 8 weeks)

  2. Virtual Reality Setup Time

    Time in minutes from VR headset placement to participant engagement with the VR environment, recorded by stopwatch on the workflow timing log by the research coordinator. Assessed in the VR + standard of care arm only.

    Measured: Day 1, from headset placement (after the pre-procedure timeout) to VR engagement, before needle insertion

  3. Virtual Reality Discontinuation Rate

    Proportion of VR + standard of care participants requiring headset removal before needle withdrawal and dressing application, with documented reason (participant request, observed distress or adverse reaction, or treating physician determination that the headset interferes with the procedure). Pre-specified feasibility benchmark: discontinuation rate below 10%.

    Measured: Day 1, from headset placement through needle withdrawal

  4. Total Procedure Duration

    Time in minutes from signing of the clinical consent for the knee injection to needle withdrawal and dressing application, recorded by stopwatch on the workflow timing log. Durations will be compared between arms to estimate time added by VR. Pre-specified feasibility benchmark: VR adds 5 minutes or less to total procedure duration.

    Measured: Day 1, from signing of procedure consent to dressing application

  5. Patient Satisfaction With the Procedure

    Participant-rated overall satisfaction with the knee injection procedure on a 0-10 Numerical Rating Scale (0 = not satisfied, 10 = completely satisfied). Higher scores indicate greater satisfaction. Reported by arm.

    Measured: Day 1, immediately following the procedure

  6. Provider-Reported Workflow Disruption

    Proportion of procedures in which the treating provider reports that the VR headset required modification to standard procedure steps (yes/no), with optional free-text description.

    Measured: Day 1, immediately following the procedure

  7. Provider-Reported Patient Comfort

    Treating provider's rating of how comfortable the patient appeared during the procedure on a 0-10 Numerical Rating Scale (0 = not comfortable at all, 10 = extremely comfortable). Higher scores indicate greater perceived comfort. Reported by arm.

    Measured: Day 1, immediately following the procedure

  8. Willingness to Use Virtual Reality Again

    Proportion of VR + standard of care participants answering "yes" to whether they would enjoy using VR in this procedure again. Pre-specified feasibility benchmark: 60% or greater.

    Measured: Day 1, immediately following the procedure

Secondary outcomes (5)
  1. Procedural Pain Ratings

    Three participant-rated items on 0-10 Numerical Rating Scales, each reported separately: (1) worst pain during the injection (0 = no pain at all, 10 = excruciating pain); (2) pain unpleasantness during the injection (0 = not unpleasant at all, 10 = excruciatingly unpleasant); (3) time spent thinking about pain during the injection (0 = none of the time, 10 = all of the time). Higher scores indicate worse outcomes on all three items. Reported by arm.

    Measured: Day 1, immediately following the procedure

  2. Anxiety During the Procedure, Adjusted for Baseline

    Participant-rated anxiety on a 0-10 Numerical Rating Scale (0 = not anxious or nervous at all, 10 = extremely anxious/nervous), measured at baseline (feeling prior to the injection) and post-procedure (feeling during the injection). Higher scores indicate greater anxiety. Procedural anxiety will be compared between arms with adjustment for baseline anxiety.

    Measured: Baseline (Day 1, after consent and before randomization) and Day 1 immediately following the procedure

  3. Change in Cybersickness Symptoms From Baseline

    Four participant-rated symptoms on 0-10 Numerical Rating Scales, each reported separately: nausea (0 = no nausea at all, 10 = vomit), dizziness/spinning sensations (0 = no dizziness at all, 10 = extreme dizziness), headache (0 = no headache at all, 10 = extreme headache), and eye strain (0 = no eye strain at all, 10 = extreme eye strain). Each is rated at baseline and post-procedure. Higher scores indicate worse symptoms. Change for each symptom is calculated as post-procedure minus baseline. Reported by arm.

    Measured: Baseline (Day 1, before randomization) and Day 1 immediately following the procedure

  4. Perceived Procedure Experience

    Three participant-rated items on 0-10 Numerical Rating Scales, each reported separately: (1) enjoyment during the injection (0 = no fun at all, 10 = extremely fun); (2) perceived speed of the procedure (0 = very slow, 5 = standard, 10 = very fast); (3) vividness of memory of the procedure (0 = no memory, 10 = indistinguishable or extremely vivid). Higher scores indicate more enjoyment, faster perceived speed, and more vivid memory, respectively. Reported by arm.

    Measured: Day 1, immediately following the procedure

  5. Perceived Distraction by the Virtual Environment

    Participant rating of how distracted they felt from the knee injection by the virtual world on a 0-10 Numerical Rating Scale (0 = not distracted at all, 10 = extremely distracted). Higher scores indicate greater distraction. VR + standard of care arm only.

    Measured: Day 1, immediately following the procedure
