The immediate changes in pain intensity and pressure pain threshold after a single high-velocity manipulation do not differ by region-specific versus non-region-specific manipulation techniques in patients with chronic low back pain.
BackgroundWhile the research design of articles published in medical journals and in
some physical therapy journals has already been evaluated, this has not been
investigated in Brazilian physical therapy journals. ObjectiveTo describe the research design used in all articles published in Brazilian
scientific journals that are freely available, have high Qualis rankings,
and are relevant to physical therapy over a 7-year period. MethodWe extracted the bibliometric data, research design, research type (human or
animal), and clinical area for all articles published. The articles were
grouped into their level of evidence, and descriptive analyses were
performed. We calculated the frequency, proportions of articles, and 95%
confidence interval of these proportions with each research design in each
journal. We cross-tabulated the clinical areas with research designs
(expressed as number and percentages). ResultsA total of 1,458 articles from four Brazilian journals were found:
Revista Brasileira de Fisioterapia, Revista
Fisioterapia em Movimento, Revista Fisioterapia e
Pesquisa, and Revista Acta Fisiátrica.
The majority of articles were classified as level II of evidence (60%),
followed by level III (29%) and level I (10%). The most prevalent research
designs were cross-sectional studies (38%), single-case or case-series
studies, and narrative reviews. Most articles reported human research and
were in the musculoskeletal, neurologic, and cardiothoracic areas. ConclusionsMost of the research published in Brazilian physical therapy journals used
levels II and III of evidence. Increasing the publication rate of systematic
reviews and randomized controlled trials would provide more high-quality
evidence to guide evidence-based physical therapy practice.
Low back pain (LBP) is extremely common and causes an enormous burden on the society. This perspective article aims to provide an evidence-based summary in the field of LBP. More specifically, we aimed to present epidemiological data on cost, diagnosis, prognosis, prevention and interventions for patients with LBP. It is critical that both clinicians and policymakers follow best practices by using high-value care for patients with LBP. In addition, nonevidence-based procedures must be immediately abandoned. These actions are likely to reduce societal costs and will improve the quality of life of these patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
