q3 · i? · review · r3

The review's discussion of its six included VR studies: face-validity ratings favoured "the appearance of the VR models to real surgery", but "participants of all six VR studies reported low haptic fidelity"; no effect size printed.

"Our study revealed favourable ratings for face validity comparing the appearance of the VR models to real surgery revealing the benefits of the model for anatomic understanding. However, participants of all six VR studies reported low haptic fidelity (Table 2)."

q2 · i? · review · r3

Sub-group analysis of Alaraj et al.'s ITACS immersive VR aneurysm-clipping simulator (17 residents): "only 12% of participants agreed that it was realistic" regarding haptic sensation, versus favourable overall usefulness ratings.

"Although the VR model was rated favourably for its use, it was limited by haptic realism as only 12% of participants agreed that it was realistic."

Discussion¶

Related Claims¶

• Neurosurgical simulation models across 18 included studies received favourable face validity ratings for visual realism, but haptic realism was a key limitation — a broader claim this one bears on
• Increased perceptual fidelity fails to reliably improve serious game learning outcomes (the fidelity fallacy) — related
• Qualitative analysis found radiation became perceptible in VR for all participants, while all reported operability differences favoring conventional training — related
• VR tools enhance acquisition and retention of clinical and procedural skills but face barriers including cybersickness, limited tactile feedback and variable long-term skill transfer — related
• Immersive technologies are rarely adopted in robotics GBL/gamification but studies using them report heightened engagement, improved spatial reasoning, and enhanced perceived realism — related
