Research paper thumbnail of Immediate changes in electroencephalography activity in individuals with nonspecific chronic low back pain after cranial osteopathic manipulative treatment: study protocol of a randomized, controlled crossover trial

BMC Complementary and Alternative Medicine, 2015

Background: Osteopathic medicine is based on a diagnostic and therapeutic system to treat tissue ... more Background: Osteopathic medicine is based on a diagnostic and therapeutic system to treat tissue mobility/ motility dysfunctions in general, using different approaches (depending on the target tissue) known as osteopathic manipulative treatment. Among the available techniques those ones addressed to the cranial field are the most questioned because of the lack of scientific evidence; but the compression of the 4th ventricle technique has been largely studied in clinical trials. Studies have shown that the technique may affect both central and autonomous nervous system, modulating some reflexes (Traube-Hering baro signal), and modifying brain cortex electrical activity through central sensitization in subjects with chronic low back pain. Thus, investigators hypothesize that the compression of the 4th ventricle may modulate peak alpha frequency (eletroencephalographic assessment) and promote physical relaxation in subjects in vigil.

Research paper thumbnail of Efficacy of musculoskeletal manual approach in the treatment of temporomandibular joint disorder: a systematic review with meta-analysis

Manual Therapy, 2015

Among these treatments, musculoskeletal manual techniques are used to improve health and healing. Objectives: To assess the effectiveness of musculoskeletal manual approach in temporomandibular joint disorder patients. Design: A systematic review with meta-analysis. Methods: During August 2014 a systematic review of relevant databases (PubMed, The Cochrane Library, PEDro and ISI web of knowledge) was performed to identify controlled clinical trials without date restriction and restricted to the English language. Clinical outcomes were pain and range of motion focalized in temporomandibular joint. The mean difference (MD) or standard mean difference (SMD) with 95% confidence intervals (CIs) and overall effect size were calculated at every post treatment. The PEDro scale was used to demonstrate the quality of the included studies. Results/findings: From the 308 articles identified by the search strategy, 8 articles met the inclusion criteria. The meta-analysis showed a significant difference (p < 0.0001) and large effect on active mouth opening (SMD, 0.83; 95% CI, 0.42 to 1.25) and on pain during active mouth opening (MD, 1.69; 95% CI, 1.09 to 2.30) in favor of musculoskeletal manual techniques when compared to other conservative treatments for TMD. Conclusions: Musculoskeletal manual approaches are effective for treating TMD. In the short term, there is a larger effect regarding the latter when compared to other conservative treatments for TMD.

Research paper thumbnail of Mechanical evaluation of elastic tubes used in physical therapy

Methods: A tensile test of elastic tubes which had seven levels of resistance identified by colors was performed. All samples (n ¼ 105; 15 samples for each color) were 7 cm of length and had two interfaces for fixation. The samples were tested in a tensile testing hydraulic machine, under elongation control, up to 200% of the original length (21 cm). The force values corresponding to an increase of 50%, 100%, 150% and 200% of the samples initial length were recorded. Results: A strong linear association between force and elongation for all colors was found. There were different forces for each elongation investigated for the same tube and between different tubes in almost all percentage of elongation investigated, except for the red and green tubes (all elongations), and for the blue and black tubes at 50% elongation. Conclusion: Mechanical tests revealed different elastic forces for different levels of elongation of each tube. The replication of the results in clinical situations is recommended, so the elastic resistance in clinical routine could be evaluated with more propriety.
