Osteopathic Manipulative Medicine and Disorders: An Overview of Peer-Reviewed Publications 2018-2022

Context Osteopathic manipulative medicine (OMM) has been claimed to be effective in various human disorders and conditions. There have been many anecdotal claims to lend credence to the efficacy of this treatment modality. Recently, much work has been done in evidence-based, government-funded projects, and clinical trials in OMM research, and these studies have further demonstrated the efficacy of OMM as direct, integrated, or complementary mechanisms in treating various conditions. Objectives As the field of OMM research has grown significantly in the past few years, we set out to analyze the peer-reviewed publications on OMM in human disorders between January 2018 and December 2022. Methods We used keywords and terms which included "osteopath," "osteopathic," osteopathic manipulative medicine," "osteopathic manipulative treatment," and "disorder," to systematically sample two public databases, PubMed and Science Direct. After the first query was recorded, we then applied more specific and stringent criteria to identify publications that (a) were written in English, (b) contained at least one human disorder/condition treated by OMM, (c) were co-authored by at least one osteopathic physician-scientist, and (d) contained at least one OMM technique. Results Our initial sampling of databases resulted in 404 publications. After applying our screening criteria, we identified and analyzed 249 (62%; 249/404) qualified publications in "OMM and Human Disorders" We then categorized them into (a) types of publications, (b) country origins of corresponding author(s), (c) groups of disorder and condition, (d) classification of the OMM used, and (e) relating the treated conditions with the five models of OMM. We found that in the 249 publications, 158 (63%) are research articles, 66 (27%) review papers, and 25 (10%) case reports. In addition, nine countries, the United States, Italy, Brazil, Spain, France, Germany, Canada, the United Kingdom (UK), and Australia contributed most of the publications of OMM. VOSviewer analysis identified a wide range of human disorders that were effectively treated with OMM. These included musculoskeletal, low back pain, neurological, headache, inflammation (including autoimmune conditions, COVID-19, lymphatic drainage), neonate/preterm infant disorders, anxiety, and dizziness. Conclusions Our comprehensive analysis showed that there has been a significant increase in peer-reviewed OMM publications in recent years, led by the United States osteopathic physician-scientists and European osteopathic scientists. OMM was found effective in treating not only common conditions such as pneumonia, low back pain, and musculoskeletal disorders, but also disorders such as inflammation, dizziness, headache, anxiety, and neonate/preterm infant disorders.
