Acupuncture for children with autism spectrum disorder: A systematic review and meta-analysis
Needles gave a weak wink toward helping ASD traits, but the proof is still too thin to act on.
01Research in Context
What this study did
Lun et al. (2023) hunted for every randomised trial that poked autistic children with needles. They found 38 studies and pooled the scores from three parent checklists: ABC, CARS, and ATEC.
The team graded each trial for bias and for how sure we can be about the numbers.
What they found
Kids in the acupuncture groups scored lower on autism symptom checklists than kids who got no needles. The difference was there, but the authors label the evidence quality “very low.”
Most trials were small and had loose blinding, so the positive signal could easily shrink or vanish with tighter methods.
How this fits with other research
This paper replaces the older review by Lee et al. (2012). That earlier paper looked at only 11 trials and called the evidence “mixed.” Lun et al. nearly quadrupled the trial count and still found the same shaky ground.
Eckes et al. (2023) also published a 2023 meta-analysis, but on full ABA programs. Their evidence base was smaller (11 studies) yet earned a “medium” effect rating with clearer risk-of-bias ratings. The contrast shows how thin acupuncture data remain next to behaviour-analytic work.
Hudson et al. (2012) reviewed psychotropic meds and likewise found only a few drugs with solid support. Together these reviews paint the same picture: novel ASD treatments often look helpful in small, weak trials that collapse under stricter scrutiny.
Why it matters
Parents will ask you about acupuncture. You can now say, “The newest review shows tiny possible gains, but the studies are too sloppy to trust.” Keep the door open for future research, yet stick with interventions that already meet evidence standards—like ABA for skill building—while we wait for sharper needle data.

03Original abstract
The aim of this study was to assess the efficiency and safety of acupuncture in core symptomatic improvement of children with autism spectrum disorder (ASD). We searched the following databases: Cochrane Library, PubMed, Embase, Medline, China National Knowledge Infrastructure (CNKI), Wanfang, Chinese Science and Technology Periodical (VIP) and Chinese Biological Medicine (CBM), from 1 January 2012 to 25 September 2022. The Autism Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS), and Autism Treatment Evaluation Checklist (ATEC) were adopted as outcome indicators. Three reviewers independently assessed the risk of bias (ROB) and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE)assessment. Utilizing Review Manager (RevMan) 5.3 and Stata 12.0, data were analyzed. A total of 38 trials were included, and 2862 participants participated in qualitative synthesis and meta-analysis. Only 1 trial was assessed as having a low ROB, and 37 trials were assessed as having an overall high ROB. The quality of evidence for most indicators were considered very low by the GRADE criteria. The results showed that acupuncture groups might have a higher clinical effective rate than nonacupuncture groups (relative risk [RR] = 1.33,95% confidence interval [CI] = 1.25–1.41; heterogeneity: x2=18.15, P = .64, I2 = 0%). Regarding changes in ABC scores, the acupuncture groups might exhibit greater decrease than nonacupuncture groups (MMD = −6.06, 95%CI = −7.25 to −4.87, P < .00001; heterogeneity: x2 =73.37, P = .03, I2 = 77%). In terms of changes in CARS score, acupuncture group may benefit more than nonacupuncture group (MMD = −3.93, 95%CI = 4.90 to −2.95, P < .00001; heterogeneity: x2=234.47, P < .00001, I2 = 90%). Additionally, in terms of ATEC score, acupuncture groups showed more benefit than nonacupuncture groups (MMD = −10.24, 95%CI = −13.09 to −7.38, P < .00001; heterogeneity: x2=45.74, P = .04, I2 = 85%). Both subgroup analysis and sensitivity analysis are existing heterogeneity. Only 1 RCT study involved adverse events with mild symptoms that did not interfere with treatment and evaluation. Children with ASD may benefit from acupuncture because of its effectiveness and safety. Nevertheless, given the low quality of the evidence for the assessed outcomes and the high ROB of analyzed trials, the results should be regarded with caution.
