PMID 40462528WHAT IT FOUND
In respiratory ICU patients, VR-assisted active limb exercises increased daily exercise time, out-of-bed time and good adherence, raised muscle strength scores, and were associated with a shorter RICU stay over a week.
Key findings
01The VR group exercised more each day than the control group, with average total daily exercise time of 56.6 minutes versus 22.4 minutes, and good adherence in 7 of 33 patients versus 1 of 35 patients.
02Muscle strength measured by the MRC score was significantly higher in the VR group than in the control group (p = 0.006), and the between-group difference strengthened over the week (p < 0.001).
03The VR group had a shorter RICU stay than the control group, 11 days versus 15 days (p < 0.05).

What it does not show
It was a small pilot at one RICU, with 68 patients, so the results may not generalise. Follow-up was short, and the authors note that longer studies and respiratory function testing are needed. The VR intervention included active limb exercises, games, feedback, and communication support, so the study cannot separate which component produced the effect. The paper does not state a pre-specified primary outcome, so the positive findings should be read as exploratory.
Declared interests
The authors declare no conflicts of interest. The research received no specific grant from public, commercial, or not-for-profit sectors.
The easy way to misread this
Do not read this as proof that virtual reality alone makes RICU patients stronger or shortens stay. It was a pilot study with 68 patients, and the VR group also received active limb exercises, games, feedback, and communication support, so the study cannot separate those components.
