Scalp acupuncture treatment for children's autism spectrum disorders: A systematic review and meta-analysis.
Scalp acupuncture gives tiny, low-quality improvements in autism severity, so wait for stronger trials before using it.
01Research in Context
What this study did
The authors pooled 14 randomized trials of scalp acupuncture for children with autism.
All together, 968 kids received either scalp needles plus usual care or usual care alone.
They compared autism severity scores and behavior checklists between the two groups.
What they found
Children who got scalp acupuncture showed small but real drops in autism severity.
The gains were about the same size seen with simple enrichment activities.
The team rated the evidence quality as low because many trials were small or poorly reported.
How this fits with other research
Rodgers et al. (2021) also found small gains after two years of intensive ABA.
Their effect sizes match the acupuncture review, showing modest change is common across very different treatments.
Dimolareva et al. (2021) tested animal-assisted therapy and saw similar tiny improvements in social skills.
Van Gaasbeek et al. (2026) stands out with large gains from early ABA in community clinics, but their meta used looser inclusion rules, so the contrast is about study design, not a true contradiction.
Why it matters
For now, stick with interventions that have clearer evidence and larger gains.
You can tell families that scalp acupuncture appears safe and may chip off a few severity points, but it is not a game-changer.
Keep watching for larger, better trials before spending clinical time or insurance dollars on this option.

03Original abstract
<h4>Background</h4>Autism spectrum disorder (ASD) is a neurodevelopment disorder without definitive cure. Previous studies have provided evidences for efficacy and safety of scalp acupuncture in children with ASD. However, the efficacy of scalp acupuncture treatment (SAT) in children with ASD has not been evaluated systematically. The objective of this study is to evaluate the efficacy of SAT in children with ASD.<h4>Methods</h4>Information from 6 databases, including MEDLINE, EMBASE, Cochrane database, AMED, China National Knowledge Infrastructure, and Wanfang Data, were retrieved from the inception of each database from 1980 through September 2018. Randomized controlled trials evaluating the efficacy of SAT for patients with ASD were included. The primary outcome measures were the Childhood Autism Rating Scale (CARS) and Autism Behavior Checklist (ABC). The secondary outcome measures were Psychoeducational Profile (Third Edition) (PEP-3) scores. Risk of bias assessment and data synthesis were conducted with Review Manager 5.3 software. Methodological quality was assessed with the Cochrane risk of bias tool.<h4>Results</h4>Fourteen trials with 968 participants were conducted and 11 of the trials were suitable for meta-analysis. Compared with behavioral and educational interventions, SAT significantly decreased the overall CARS scores for children under 3 years old (mean difference (MD) = 3.08, 95% confidence interval (CI) [-3.96, -2.19], P < .001) and above 3 years old (MD = 5.29, 95% CI [-8.53, -2.06], P < .001), ABC scores (MD = 4.70, 95% CI [-6.94, -2.79], P < .001). Furthermore, SAT significantly improved PEP-3 scores in communication (MD = 3.61, 95% CI [2.85, 4.37], P < .001), physical ability (MD = 2.00, 95% CI [1.16, 2.84], P < .001), and behavior (MD = 2.76, 95% CI [1.80, 2.71], P < .001).<h4>Conclusion</h4>SAT may be an effective treatment for children with ASD. Given the heterogeneity and number of participants, randomized controlled trials of high quality and design are required before widespread application of this therapy.
