The aims of this bibliometric analysis are to describe the characteristics of articles published on the efficacy of osteopathic interventions and to provide an overall portrait of their impacts in the scientific literature. A bibliometric analysis approach was used. Articles were identified with searches using a combination of relevant MeSH terms and indexing keywords about osteopathy and research designs in MEDLINE and CINAHL databases. The following indicators were extracted: country of the primary author, year of publication, journals, impact factor of the journal, number of citations, research design, participants’ age group, system/body part addressed, primary outcome, indexing keywords and types of techniques.
A total of 389 articles met the inclusion criteria. The number of empirical studies doubled every 5 years, with the United States, Italy, Spain, and the United Kingdom being the most productive countries. Twenty-three articles were cited over 100 times. Articles were published in 103 different indexed journals, but more than half (53.7%) of articles were published in one of three osteopathy-focused readership journals. Randomized control trials (n = 145; 37.3%) and case reports (n = 142; 36.5%) were the most common research designs. A total of 187 (48.1%) studies examined the effects of osteopathic interventions using a combination of techniques that belonged to two or all of the classic fields of osteopathic interventions (musculoskeletal, cranial, and visceral).
The authors concluded that this bibliometric analysis shows that publications about efficacy of osteopathy are relatively recent and have increased at a rapid pace over the last three decades. More than half of these publications are published in three osteopathic journals targeting a limited, disciplinary-focused readership. Our results highlight important needs for large efficacy and effectiveness trials, as well as study designs to further understanding of the mechanisms of action of the techniques being investigated. Finally, this bibliometric analysis can assist to identify osteopathy techniques and populations where further clinical research is required.
What the authors fail to state is that their analysis discloses osteopathy to be an area of utter unimportance. Less than 400 studies in 52 years is a dismal result. The fact that they were mostly published in journals of no impact makes it even worse. Twenty-three articles were cited more than 100 times; this is dismal! To put it in perspective, I have ~250 articles that were cited more than 100 times. Does that suggest that my work has made about 10 times more impact than the entire field of osteopathy?
