Abstract
Short, A. D., Chen, H., Hulks, V., & Scerif, G. (2025). Non-pharmacological interventions targeting motor difficulties in neurodivergent children: A systematic review. Neurodiversity, 3. https://doi.org/10.1177/27546330241310175. (Original work published 2025)
The authors regret that there were errors in reporting the study by Drobnyk and colleagues (2019), who assessed the efficacy of Ayres Sensory Integration on children with Rett syndrome. The publication in Neurodiversity reported that there were marked declines in motor skill use following their intervention, which does not accurately reflect their findings of a small but not statistically significant increase in the number of grasps at the end of the post-intervention period, compared to the end of the baseline. Additionally, the use of the term “marked” in reference to the studies reviewed in the manuscript may be interpreted as “large” when instead it was intended as “reported”. These errors comprise a small part of the findings, and overall, our conclusions remain unchanged.
The correction to the extraction table includes the first line with “Drobnyk et al., 2019” in the “Study” column. Here, the “Intervention outcome” column should report “no change” and the “intervention type” columns (both the Extraction table and the table at the beginning “Objectives” section) should be re-labeled as “sensory-based” in reference to Drobnyk et al., (2019). “ Sensory-based” interventions include vestibular stimulation, tactile stimulation, vibration therapy, sensorimotor stimulation, and sensory integration. In addition, in the Results section under Objective 1, in the first paragraph, the text should read: “Only two studies showed reduction in motor abilities (Lotan et al., 2004; Schleien et al., 1988)”. In the second paragraph of the same section, the correction reads that “Similarly, only one intervention conducted three times a week had mixed findings (Mraz et al., 2016) and one intervention had a small but not statistically significant impact on motor skills (Drobnyk et al., 2019). Under Objective 2 in the Results section, the correction reads that “Of the studies that focused on fine motor skills, six showed improvements, while one resulted in declines (Logan et al., 2014).”
The Journal Editor confirmed that the changes to the article alter the results but do not change the conclusions.
The authors of the systematic review would like to apologise for any inconvenience that these errors may have caused.
