Does it work, measured properly?
Usability studies, clinical trials, and outcome measurement against a defined endpoint.
Unsolved engineering problems at this stage, each linked to work documenting the difficulty.
An augmented overlay is only useful if it sits exactly where the anatomy is. Registration has to survive patient movement, soft-tissue shift, and a surgeon's changing viewpoint, and the error budget is millimetres.
Headsets record rich data — gaze, movement, timing — and it is tempting to treat it as assessment. Establishing that those numbers correspond to real clinical ability is a separate and harder task.
A participant inside a headset knows whether the experience is therapeutic, so convincing placebo conditions and masking are hard to build. Trials often settle for blinding only the analysts, which leaves room for expectation effects.
Session length, weekly frequency and total course vary widely between VR trials, and the best-performing settings differ by outcome and population. Without a standard dose, studies are hard to compare and a product's labelled regimen is hard to justify.
Many VR studies measure change during or just after exposure. Evidence that effects persist weeks later, especially for chronic conditions, is thinner and inconsistent, which limits clinical and payer confidence.
Children undergoing short but painful procedures experience distress that sedation cannot always address, and fear compounds the pain itself.
In crises such as vaso-occlusive episodes, pain is severe and escalating analgesia carries its own risks, leaving a gap for non-pharmacological adjuncts.
Higher fidelity costs more and is assumed to teach better, but which cues change behaviour — and which are decoration — is rarely tested.
Competence is still largely judged by observation, which is expensive, inconsistent between assessors, and hard to schedule.
Recovery needs many repetitions of movement that is difficult, tiring, and unrewarding to perform, so adherence and intensity both suffer.
Findings about how movement is relearned are well established in the laboratory and slow to reach the treatment room.
