Global trends in physical activity research of attention-deficit/hyperactivity disorder: A scientometric study...

Increasing evidence shows that physical activity interventions can improve attention-deficit/hyperactivity disorder (ADHD) symptoms. However, understanding of its etiology, treatment, and intervention remains limited. This study systematically analyzes literature from 2000 to 2004 to understand current knowledge, status, and predict future trends, aiming to offer clinicians and researchers a comprehensive perspective and reference for future studies.

A comprehensive literature search was conducted in the Web of Science Core Collection. Cite Space (version 6.1.R3) and visualization of similarities viewer (version 1.6.10) were employed for data visualization and analysis of publication outputs, collaborative networks, keyword co-occurrence, and co-citation patterns. This bibliometric review was conducted in accordance with the BIBLIO Checklist.

Analysis of 569 articles shows an increasing trend in publications. The United States (279 articles), China (83 articles), and Germany (51 articles) lead in publication volume. Research is concentrated in universities, with Harvard Medical School (17 publications) at the forefront, followed by Natl Taiwan Normal University and University of Wisconsin (14 publications). Authors Chang, Yu-Kai, and Hung, Tsung-Min have the most publications (13 publications). The most cited reference is "DSM-5" with 94 citations. Keywords "ADHD" (172 times), "physical activity" (155 times), and "exercise" (94 times) are the most frequent.

This study highlights the global rise in research on physical activity interventions for ADHD, with the United States leading in output and influence. Physical activity is emphasized as a promising complement or alternative to traditional treatments, offering potential benefits for ADHD symptom management. Key authors, institutions, and collaborations are identified, providing insights into research trends and hotspots. The findings serve as a valuable resource for advancing the understanding and practical application of physical activity interventions. Greater interdisciplinary and regional collaboration is essential for driving innovation and translating research into effective solutions for ADHD management.
