Effectiveness of Virtual Reality-Based Early Rehabilitation Strategies on Pain, Sleep, Anxiety, Balance, Cognition, and Limb Motor Function in Adult Intensive Care Unit Patients: Systematic Review and Meta-Analysis of Randomized Controlled Trials.

The meta-analysis ( Figure 10 ) indicated that, based on the average effect, VR-ERI showed a trend toward improving patients’ limb motor function at short-term follow-up after discharge compared to usual care (SMD 1.40, 95% CI −0.23 to 3.02), although the difference was not statistically significant and requires further verification.
