Design and validation of a virtual reality trainer for ultrasound‐guided regional anaesthesia
Authors' conclusion
This study achieved initial validation of our new virtual reality trainer and allows progression to a planned definitive trial that will compare the effectiveness of virtual reality training on real-life regional anaesthesia performance.
Study context
- Population
- Novice and experienced regional anaesthetists performing 40 needling attempts on four virtual nerve targets
- Participants
- 21 vs 15
- Comparison
- Novice vs Experienced
- Novicen = 21reference
- Experiencedn = 15
- Outcome
- Construct validity: performance scores (needle angulation, withdrawals, time taken) between novice and experienced regional anaesthetists

Performance
As reported in the abstract
Needling performance scores (construct validity)
- Experienced vs Novice: P = 0.002
- Experienced vs Novice: P = 0.002
- Experienced vs Novice: P = 0.003
- Experienced vs Novice: P = 0.002
- Experienced vs Novice: P = 0.003
Secondary outcomes
Learning curves (log-log transformed)
- Individual variability in performance over time
Immersion (Presence Questionnaire) vs other high-fidelity VR software
- Comparable in realism, possibility to act and quality of interface subscales
- all p > 0.06
- Not comparable in possibility to examine and self-performance subscales
- all p < 0.009
Cognitive workload (NASA-Task Load Index) vs real-life procedural medicine
- Workloads similar to real-life procedures
- P = 0.53
