The assessment of thoracic pain

Dry needling for the management of thoracic spine pain

Thoracic spine pain is as disabling as neck and low back pain without receiving the same level of attention in the scientific literature. Among the different structures that can refer pain to the thoracic spine, muscles often play a relevant role. Trigger points (TrPs) from neck, shoulder and spinal muscles can induce pain in the region of the thoracic spine. There is a lack of evidence reporting the presence of TrPs in the region of the thoracic spine, but clinical evidence suggests that TrPs can be a potential source of thoracic spine pain. The current paper discusses the role of TrPs in the thoracic spine and dry needling (DN) for the management of TrPs in the thoracic multifidi and longissimus thoracis. This paper also includes a brief discussion of the application of DN in other tissues such as tendons, ligaments and scars.

Low back pain prevalence in Brazil: a systematic review

The article describes the methodological quality of published studies on prevalence of low back pain in Brazil. Eighteen studies were considered eligible after searches in the following electronic databases: LILACS, PubMed, Embase, CINAHL, SPORTDiscus and SciELO. A high source of bias was observed in the criteria for external validity related to sampling, in addition to non-response bias. Considering the criteria for internal validity, the main sources of bias were the lack of an acceptable definition of low back pain and the use of instruments that lacked proven reliability and validity. No representative study was found that provides a generalizable prevalence of low back pain in Brazil. The published studies included in this review showed a high risk of bias that affects the prevalence data. Future studies with appropriate methodological design are necessary to verify the real impact of low back pain in Brazil and allow comparisons.
