The research team, led by Meng Chen and Mengzhi Li of Hanyang University in South Korea, conducted an exhaustive search of both English-language and Chinese databases, including PubMed, Web of Science, the Cochrane Central Register of Controlled Trials, Embase, CNKI, Wanfang, VIP, and CBM, covering all literature from database inception through 23 December 2025. This bilingual search strategy is significant because it captured a substantial body of intervention research conducted in China that conventional English-only reviews frequently miss, broadening the evidence base considerably beyond what most prior meta-analyses on the topic have been able to include.

Network meta-analysis is a statistical technique that goes beyond traditional pairwise comparisons. Instead of only pooling studies that directly compare one intervention against a control group, it builds a network of all treatments across all trials, allowing both direct and indirect comparisons between interventions that may never have been tested head to head. This matters in a field where a given trial might compare balance training with trampoline exercise, while another compares core stabilization with hippotherapy, leaving clinicians with fragmentary and seemingly contradictory findings. By integrating the entire network of evidence, the method can rank interventions by their probability of being the most effective.

The interventions evaluated in the included trials spanned a remarkable range. They included conventional balance training, core stabilization and core strength programs, functional training, sensory integration and sensory rehabilitation approaches, trampoline and jumping exercises, rope skipping, hippotherapy, aquatic exercise, virtual reality training, floor hockey and floorball, fun athletics programs, hemsball, simplified boxing routines, and combined aerobic and resistance exercise programs. Outcome measures focused on static and dynamic balance as well as motor coordination, the twin pillars of gross motor function that determine how confidently and capably young people move through their environments.

Based on the ranking probabilities generated by the network model, functional training delivered alongside sensory rehabilitation programs emerged at the top for both balance and coordination outcomes. Functional training emphasizes movements that mimic real-world tasks such as squatting, reaching, stepping, and weight shifting, which may explain its advantage: rather than isolating a single physical capacity, it trains the integrated postural control system that children must deploy in everyday situations. Pairing it with sensory rehabilitation, which targets the vestibular, proprioceptive, and visual inputs that feed postural control, appears to attack the balance problem from both the musculoskeletal and the sensory-processing sides simultaneously.

The findings arrive at a moment of growing concern about motor development in this population. Previous research has documented that children and adolescents with intellectual disability show measurably poorer postural sway, slower reactive balance, and weaker functional strength than typically developing peers, and that sedentary periods, including those caused by pandemic-related inactivity, further erode motor skills. Poor balance is not merely an athletic limitation; it is a fall risk factor and a barrier to social participation, independence, and the physical fitness that underpins long-term health. An evidence-based hierarchy of interventions therefore has consequences well beyond the gymnasium.

The study followed rigorous methodological standards, adhering to the PRISMA 2020 reporting guidelines and its extension for network meta-analyses, and assessing the risk of bias in the included randomized trials with the revised Cochrane RoB 2 tool. The authors reported no funding source for the study and declared no competing financial interests. The work was conducted by researchers at the Department of Sports Science at Hanyang University ERICA and the Department of Dance at Hanyang University, with Meng Chen and Mengzhi Li contributing equally as co-first authors and Zhenping Jiang serving as corresponding author.

For practitioners, the practical message is encouraging. Exercise interventions of many kinds appear to improve motor function in young people with intellectual disability, meaning that almost any structured physical activity is likely better than none. But when resources are limited and choices must be made, the evidence now points toward programs that combine functional, task-oriented movement with deliberate sensory challenge. The authors caution that the findings represent ranking probabilities across a heterogeneous trial network rather than a definitive prescription, and they call for further high-quality trials to refine dosing, duration, and intensity recommendations. Still, for a population too often excluded from the benefits of exercise science, this analysis provides a clear, evidence-based starting point for building stronger, steadier, more capable movers.

The study, conducted by a team of clinicians and researchers at Hasanuddin University and Dr. Wahidin Sudirohusodo General Hospital in Makassar, Indonesia, set out to address a stubborn evidence gap. While immersive virtual reality rehabilitation has accumulated a growing body of support in populations ranging from stroke survivors to children with cerebral palsy, rigorous trial data in children with Down syndrome have remained scarce. Children with the condition face a distinctive constellation of motor challenges—hypotonia, ligamentous laxity, balance impairments, and delays in fundamental movement skills such as running, galloping, throwing, and catching—that make task-oriented, engaging practice especially valuable yet especially hard to sustain in conventional therapy settings.

The researchers enrolled ten children with Down syndrome, all aged ten, though with varying cognitive developmental ages, and randomly allocated them to one of two groups. Five children received immersive reality-based training while the other five received conventional motor training. Both groups completed supervised sessions twice weekly for six weeks, an intensity deliberately chosen to mirror what could realistically be delivered in a rehabilitation clinic. Outcomes were tracked with the Test of Gross Motor Development, Second Edition, a widely used and well-validated standardized instrument that yields a composite Gross Motor Quotient along with subtotals for locomotor and object-control skills. Assessments were performed at four time points: baseline, during the intervention, immediately after the intervention ended, and again at follow-up.

The numbers tell a striking story. In the immersive reality group, the Gross Motor Quotient climbed from 52.60, with a standard deviation of 4.93, at baseline to 75.40, again with a standard deviation of 4.93, by the end of the study. The conventional training group also improved substantially, rising from 61.60, with a standard deviation of 5.77, to 75.40, with a standard deviation of 2.51. Both trajectories represent clinically meaningful movement toward the standardized normative range, but the immersive reality group’s absolute change was greater, largely because those children started from a lower baseline. The researchers were careful to flag that this baseline imbalance between groups complicates any claim that immersive reality training is inherently superior; the difference in starting scores means the comparison must be interpreted with considerable caution.

Equally important as the score improvements is what the study did not find: no adverse events of any kind. Every one of the ten children completed the full intervention and the follow-up assessment, and session attendance was a remarkable 100 percent across both groups. For a population in which attention, motivation, and sensory processing differences can make repetitive therapy difficult to tolerate, that level of engagement is itself a meaningful result. The authors note that the immersive format appears to have been well tolerated by all participants, lending support to the idea that interactive, game-like environments can hold the attention of children with intellectual disabilities in ways that conventional drill-based exercises sometimes cannot.

The theoretical rationale behind the intervention draws on established principles of motor learning. Immersive reality systems allow therapists to embed repetitive, task-oriented practice inside multisensory environments that deliver immediate, continuous feedback about performance. Rather than asking a child to practice stepping, reaching, or balancing in a bare clinical room, the virtual environment transforms each repetition into a goal-directed activity with visible consequences and rewards. Research in other pediatric populations, including systematic reviews of virtual reality interventions for cerebral palsy, has suggested that when motor learning principles such as high repetition, augmented feedback, and progressively calibrated challenge are integrated into virtual environments, functional gains can follow. The Makassar team translated this framework, largely untested in Down syndrome, into a structured pediatric rehabilitation protocol.

The broader context underscores why even a small pilot study in this population matters. Global burden-of-disease analyses estimate that Down syndrome affects millions of people worldwide, and studies consistently document that children and adolescents with the condition show reduced postural balance, weaker trunk and lower-limb muscle performance, and delayed acquisition of fundamental movement skills compared with peers. These deficits are not merely cosmetic; fundamental movement skills in childhood predict physical activity levels, fitness, and health-related outcomes later in life. Exercise interventions targeting balance and motor skills in Down syndrome have shown promise in systematic reviews, but adherence and engagement remain persistent obstacles—precisely the obstacles that immersive, game-based formats are designed to overcome.

The authors are candid about the limitations of their work. A sample of ten children split between two arms is far too small to support definitive conclusions about efficacy, and the baseline imbalance in Gross Motor Quotient between groups means the apparent advantage for immersive reality training could partly reflect regression toward the mean rather than a true treatment effect. All participants were the same chronological age, which strengthens internal consistency but limits generalizability across the wide developmental range of childhood. The pilot was designed, as the name implies, primarily to test feasibility, safety, and signal detection—questions that this study answers affirmatively—rather than to serve as definitive evidence of superiority over conventional care. The researchers explicitly call for larger trials to evaluate immersive reality-based training as a complementary modality in pediatric motor rehabilitation.

Still, the convergence of findings is hard to ignore. Both training approaches moved children toward normative motor scores over the same six-week window, suggesting that structured, supervised practice of any kind delivers real benefits. The immersive reality group’s larger absolute gain, its perfect attendance record, and the complete absence of adverse events together paint a picture of a technology that is ready to be tested at scale. The study also adds Indonesia’s voice to a research landscape dominated by high-income countries, demonstrating that sophisticated rehabilitation technology trials can be conducted in public hospital settings in Southeast Asia, where the majority of the world’s children with Down syndrome actually live.

For families, therapists, and policymakers watching the rapid maturation of virtual reality rehabilitation, the message from Makassar is one of guarded optimism. Immersive reality-based training appears feasible, safe, and engaging for children with Down syndrome, and it was associated with improved standardized gross motor outcomes over a short intervention period. The next generation of studies will need larger and more diverse samples, longer follow-up to test whether skills transfer to real-world playgrounds and classrooms, and designs that balance groups at baseline. If those trials confirm what this pilot hints at, the headsets now appearing in rehabilitation clinics may become a routine part of helping children with Down syndrome run, jump, and play with confidence.

Autism spectrum disorder is a heterogeneous neurodevelopmental condition characterized by persistent difficulties in social communication and interaction, along with restricted, repetitive patterns of behavior or interests. Epidemiological surveillance across the globe has documented a steady rise in prevalence, intensifying the search for interventions that go beyond the current standards of care. Behavioral therapies remain the cornerstone of treatment, and medications can address certain comorbidities such as irritability or attention problems, but their efficacy for core symptoms is limited. That gap has prompted researchers to look toward metabolic approaches, including the ketogenic diet, a high-fat, low-carbohydrate regimen long used to treat refractory epilepsy.

The rationale for testing a ketogenic diet in autism rests on several converging lines of biological evidence. Ketone bodies, produced by the liver when carbohydrate intake is sharply restricted, serve as an alternative fuel for the brain and can alter neurotransmitter balance, mitochondrial function, and oxidative stress, all of which have been implicated in autism-related neurobiology. Animal models and small clinical studies have previously hinted at behavioral benefits, but large, well-controlled trials in young children have been scarce. The new study was designed to address that evidence gap with a prospective, randomized design and validated clinical outcome measures.

Between January 2024 and January 2025, the research team enrolled 62 young children diagnosed with autism spectrum disorder who were admitted to Hefei Maternal and Child Health Hospital. Participants were randomly assigned in equal numbers, 31 per group, to a treatment group or a control group. Both groups underwent an identical rehabilitation program consisting of hospital-based training on weekdays and home-based rehabilitation on weekends across a two-month period. The only difference between the arms was dietary: the treatment group additionally received a modified ketogenic diet built around ketogenic nutritional powder and a structured dietary plan.

The dietary protocol was deliberately engineered for real-world feasibility in families with young children. On training days, lunch was provided at the hospital, ensuring direct supervision of a substantial portion of daily intake, while breakfast, dinner, weekend dietary implementation, and home monitoring were managed by caregivers following the structured plan. The control group, by contrast, maintained a regular diet throughout the same rehabilitation program. This hybrid delivery model, combining clinical oversight with caregiver administration, reflects a pragmatic attempt to test whether a modified ketogenic approach can be implemented outside highly controlled metabolic wards, a persistent obstacle in pediatric dietary research.

Symptom change was assessed with two widely used clinical instruments: the Autism Behavior Checklist, known as the ABC, and the Childhood Autism Rating Scale, or CARS. Both scales quantify the severity and breadth of autism-related behaviors, with higher scores indicating more pronounced symptoms. After two months of intervention, both groups showed statistically significant reductions in ABC and CARS scores compared with their own baselines, indicating that the rehabilitation program itself conferred measurable benefit to all participants.

The decisive comparison, however, lay between the groups. When the researchers examined individual change scores, children receiving the modified ketogenic diet demonstrated significantly larger reductions on both measures. The between-group difference in ABC change scores reached statistical significance with a Mann-Whitney U statistic of 324.000 and a p-value of 0.027, while the CARS comparison yielded an even stronger signal, with U equal to 273.500 and a p-value of 0.003. In practical terms, adding the dietary intervention appeared to amplify the improvements attributable to rehabilitation training over the short term.

The authors conclude that in this cohort of young children with autism, the modified ketogenic diet combined with rehabilitation training was associated with greater short-term reductions in ABC and CARS scores than rehabilitation alone, and that the intervention demonstrated acceptable short-term feasibility. The use of ketogenic nutritional powder rather than a strictly classical ketogenic diet likely contributed to tolerability, since modified formulations can ease the burden of achieving and maintaining ketosis in children who are often selective eaters. Caregiver-mediated home implementation, supported by hospital-provided meals on training days, offers a template for how metabolic interventions might be scaled in clinical rehabilitation settings.

Nevertheless, the trial has boundaries that temper interpretation. The intervention lasted only two months, leaving open whether gains persist, plateau, or erode over longer follow-up. The sample, while adequate for detecting between-group differences, comprised children from a single hospital, raising questions about generalizability across demographic and clinical profiles. Blinding is notoriously difficult in dietary trials, as caregivers inevitably know what their children are eating, and outcome assessments may be influenced by expectations despite the use of standardized rating scales. The study was registered with the China Clinical Trial Registry under identifier ChiCTR2300075057 on 24 August 2023, and was funded by the Hefei Health Commission Research Fund, with no competing interests declared by the authors.

Even with those caveats, the results represent one of the more encouraging randomized evaluations of ketogenic dietary therapy in pediatric autism to date. They align with a broader shift in neuroscience toward viewing metabolic health as a modifiable lever in neurodevelopmental disorders, echoing the diet’s established success in epilepsy and emerging studies in conditions ranging from schizophrenia to Alzheimer’s disease. Larger, longer, and preferably multicenter trials will be needed to confirm the effect, identify which children benefit most, and define the optimal formulation and duration of treatment. For now, families and clinicians have reason for cautious optimism that a carefully supervised modified ketogenic diet may offer a meaningful complement to rehabilitation in early autism intervention.

Beyond the headline results, the trial offers a window into the practical physiology of ketogenic therapy in early childhood. When carbohydrate intake falls sufficiently low, hepatic metabolism shifts toward producing beta-hydroxybutyrate and acetoacetate, molecules that cross the blood-brain barrier and supply neurons with an energy substrate that yields more ATP per unit of oxygen than glucose. This metabolic flexibility matters in neurodevelopmental conditions, because a growing body of work links mitochondrial electron transport chain dysfunction and impaired cellular energy supply to subsets of autism spectrum disorder. By providing an efficient alternative fuel, ketogenic approaches may partially bypass compromised glucose utilization, which neuroimaging studies have occasionally documented in affected brain regions.

The clinical instruments used in the trial deserve closer attention for readers unfamiliar with pediatric assessment tools. The Autism Behavior Checklist originated in the 1980s as one component of the Autism Screening Instrument for Educational Planning and contains 57 items spanning sensory, relational, body and object use, language, and social domains, typically completed by caregivers or teachers. The Childhood Autism Rating Scale, developed by Eric Schopler and colleagues, contrasts a child’s behavior against age-typical norms across fifteen domains, with scores above a conventional threshold supporting an autism diagnosis. Because both instruments rely on observed behavior rather than biomarkers, their scores can fluctuate with context, rater training, and the child’s daily state, which is why randomized designs that balance such noise across arms carry particular weight.

Safety considerations loom large whenever a ketogenic regimen is proposed for young children, whose growth demands stable nutrition. Classical ketogenic diets, long deployed in epilepsy centers, carry recognized risks including constipation, dyslipidemia, kidney stones, and slow weight gain, and they typically require vitamin and mineral supplementation alongside careful monitoring of lipids, urine ketones, and growth trajectories. Modified variants relax the strict fat-to-carbohydrate ratios of the classical approach, trading some ketone elevation for improved palatability and adherence. In this study, the use of a powdered nutritional formulation with a structured plan suggests an attempt to standardize intake precisely because free-form ketogenic cooking in children, who frequently exhibit food selectivity, is difficult to control and document.

The shared improvement observed in both arms also merits interpretation. Intensive rehabilitation, with its predictable routines, structured social exposure, and engaged caregivers, is itself an active intervention, and the design wisely treated it as the comparator standard rather than an untreated baseline. Against that backdrop, the dietary supplement’s incremental effect on rating scale scores, while statistically robust by nonparametric testing, was measured over a window short enough that regression to the mean and heightened caregiver attention in the treatment group cannot be fully excluded. Objective correlates, such as sleep quality, gastrointestinal symptoms, attention measures, or biochemical markers of ketosis, would strengthen causal confidence in future work.

Looking forward, the field would benefit from trials that enroll diverse populations, stratify participants by metabolic or mitochondrial phenotype, and track outcomes well beyond the initial months of intervention. Dose-response relationships, the durability of ketosis achieved at home, and the identification of responder subgroups all represent open questions. If replicated at scale, a metabolically informed adjunct to behavioral rehabilitation could reshape early intervention pathways, but until then the present findings are best viewed as a promising signal that justifies expansion of controlled investigation rather than a basis for unsupervised dietary change outside clinical guidance.
