Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Across the 18 included studies, all assessed face validity and rated visual realism favourably, while haptic realism was a key limitation. → Chawla Shreya 2022

q3 · i? · review · r3
Systematic review of 18 studies (1204 screened) validating neurosurgical simulation models for four skull-base procedures. The review reports that "all studies rated visual realism favourably, but haptic realism was key limitation" across cadaver, animal, synthetic, and VR model types.
"All studies assessed face validity, 11 assessed content, and 6 assessed construct validity. Animal models (n = 5), synthetic models (n = 7), and VR models (n = 6) were assessed. In face validation, all studies rated visual realism favourably, but haptic realism was key limitation."
Discussion¶
Related Claims¶
- VR neurosurgical simulators show favourable visual realism but low haptic fidelity, with only 12% of participants in one study agreeing haptics were realistic — a narrower finding that bears on this claim
- 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
- Synthetic models ranked a high median tactile realism (4 out of 5) compared to other model types and were rated most convenient for remote training — related
