Introduction: Cerebral palsy (CP) affects motor function development, requiring intensive rehabilitation. Virtual reality (VR) interventions show promise for improving motor learning through immersive, engaging experiences. This systematic review and meta-analysis evaluated VR effectiveness for motor function improvement in children with CP. Methods: Following PRISMA 2020 guidelines, we searched six electronic databases from inception to 15 June 2025. Included studies compared VR interventions versus control conditions in children with CP (ages 4–18 years), measuring motor function outcomes. Sixteen studies (n = 397 participants) met the inclusion criteria for qualitative synthesis. Random-effects models, subgroup analyses, and meta-regression were performed. Evidence certainty was evaluated using GRADE methodology. Results: Five randomized controlled trials with complete extractable data (N = 190 participants, 40 effect sizes) were included in the primary quantitative meta-analysis. The primary meta-analysis demonstrated moderate overall effects favoring VR interventions (standardized mean difference [SMD] = 0.41, 95% CI [0.16, 0.66], p = 0.001; I² = 74%); however, GRADE quality was rated LOW due to risk of bias and imprecision. Technology type critically moderated outcomes: robotic exoskeleton systems showed large effects (SMD = 1.00, p = 0.002), commercial gaming platforms showed small-to-moderate effects (SMD = 0.38, p = 0.013), while custom VR systems showed no significant benefit (SMD = 0.01, p = 0.905; Q = 29.00, p < 0.001). Age emerged as the strongest moderator: children (<6 years) demonstrated significant benefits (SMD = 0.98, p < 0.001), whereas school-age children (6–12 years) showed no effect (SMD = −0.01, p = 0.903; meta-regression slope = −0.236 per year, p < 0.001). Dose–response was non-linear, with optimal benefits at 30–40 intervention hours and diminishing returns beyond 50 h. VR proved superior to standard care (SMD = 0.83) but not to active intensive therapies (SMD = 0.09). The safety profile was favorable (1.3% adverse event rate, no serious events). No publication bias was detected. Conclusions: VR interventions demonstrated moderate, technology-dependent motor function improvements in children with CP, with benefits concentrated in young children using robotic systems. Evidence certainty is low, requiring further high-quality trials. Implementation should prioritize robotic VR for children with 30–40 h protocols.

Globally, 1 in 10 children are impacted by war, with over 24,000 violations documented in 2020 alone. These children face persistent mental health challenges, including anxiety, depression, and posttraumatic stress disorder (PTSD). This systematic review evaluates current psychological interventions for war-affected children. Following PRISMA guidelines, 10 studies (2013–2021) from conflict zones in non-high-income countries were analyzed. Clinical interventions such as the Teaching Recovery Techniques (TRTs) are crucial; TRT is a low-cost intervention implementable by trained nonprofessionals under supervision. Findings revealed that TRT showed promise, especially when combined with parenting sessions, underscoring the importance of caregiver involvement. School-based programs were effective in addressing PTSD and anxiety symptoms, highlighting the key role of schools and trained teachers. Reading interventions improved affect recognition, and life-skills approaches enhanced social coping, but the most impactful strategies integrated caregivers. Successful interventions combined parental and community support, emphasizing cultural adaptation and individualized approaches for sustained mental health improvements.
