    ObjectiveThe objective of this study was to analyze the trends in publications on intrathecal baclofen (ITB) therapy.MethodsWe searched Elsevier's Scopus database in February 2022 to find articles focused on ITB therapy. Data extracted included citation count, publication year, author's country and income category, journal and its 5-year impact factor, research type, disease requiring ITB, and target population.ResultsThe analysis covered 615 articles from 1985 to 2022. The average citation count per article was 27.47 (95% confidence interval 23.75-31.18) and the mean impact factor was 4.54 (95% confidence interval 3.84-5.24). The majority (76.42%) were primary research, with 8.1% being interventional and 91.9% observational. Even so, one half of the top ten most cited were interventional. Secondary research and case reports made up 12.68% and 10.73% respectively, with narrative reviews making up most of the secondary research (79.48%). Only 1 study conducted a meta-analysis. The United States was the most prolific country. High-income countries published 96.42% of articles.ConclusionsThe rising number of ITB articles and citations indicates growing interest and expanding knowledge in this field. However, there's a notable scarcity of research from low- and middle-income countries, particularly those with high prevalence of ITB-treatable diseases. The need for more evidence to overcome potential barriers to ITB implementation is emphasized. Despite an increasing number of publications, a large proportion presented low levels of evidence, such as case reports and narrative reviews, highlighting the need for more rigorous research methods to solidify the evidence base for ITB therapy.Copyright © 2023.
