RESUMO
Myofascial pain syndrome (MPS), trigger points (TrPs), and dry needling (DN) continue to be of interest to researchers and clinicians worldwide. In this quarterly overview, we included studies from 19 countries, including Pakistan, Iran, Spain, Israel, the US, Australia, Turkey, the UK, China, Italy, Germany, Brazil, Denmark, Canada, Saudi Arabia, Egypt, India, New Zealand, and Thailand. As encouraging as it may be that myofascial pain is being considered worldwide, it is frustrating how many studies do not include a proper control group making them not very useful. It is not clear why researchers would go through the trouble of setting up a study, which requires many hours of work and dedication, and not produce a meaningful paper for clinicians and researchers alike. Fortunately, several papers are high quality studies. This overview covers 39 basic research studies, systematic reviews and meta-analyses, clinical studies, and a few case reports.
