Background An updated summary of the evidence for the reliability of the Mechanical Diagnosis and Therapy (MDT) system in patients with spinal pain is needed. Objective To investigate the evidence on the intrarater and interrater reliability of MDT in patients with spinal pain. Methods Searches in MEDLINE, CINAHL, Embase, PEDro, and Scopus were conducted for this systematic review. We included any study design as long as reliability of the MDT method was tested in patients with spinal pain. We collected data on the reliability of MDT to identify main and subsyndromes, directional preference, the centralization phenomenon, and lateral shift. The methodological quality of studies was assessed using the Quality Appraisal of Diagnostic Reliability and the Guidelines for Reporting Reliability and Agreement Studies checklists. Results Twelve studies were included (8 studies on back pain, pooled n = 2160 patients; 3 studies on neck pain, pooled n = 45 patients; and 3 studies recruited mixed spinal conditions, pooled n = 389 patients). Studies investigating patients with back pain reported kappa estimates ranging from 0.26 to 1.00 (main and subsyndromes), 0.27 to 0.90 (directional preference), and 0.11 to 0.70 (centralization phenomenon). Kappa estimates for studies investigating neck pain ranged from 0.47 to 0.84 (main and subsyndromes) and 0.46 (directional preference). In mixed populations, kappa estimates ranged from 0.56 to 0.96 (main and subsyndromes). Conclusion The MDT system appears to have acceptable interrater reliability for classifying patients with back pain into main and subsyndromes when applied by therapists who have completed the credentialing examination, but unacceptable reliability in other therapists. We found conflicting evidence regarding the reliability of the MDT system in patients with neck pain or mixed pain locations. J Orthop Sports Phys Ther 2018;48(12):923–933.

Background: It is well accepted that pain in brachial plexus injury (BPI) have a major neuropathic component, but the nociceptive aspects may play an important role in the generation and maintenance of pain in patients with PBI and should be investigated also. An example of a source of nociceptive pain in these individuals is the involvement of myofascial trigger points. Aim: To estimate the prevalence of myofascial pain in individuals with BPI. Methods: This was a cross-sectional study with 31 volunteers who had suffered traumatic BPI, and were treated for a two-year period in three reference centers. All participants were evaluated for the presence of trigger points (TP) in specific muscles. Their demographic and clinical data related to injury and pain were collected in an evaluation form that included the Visual Analogue Scale, Brief Pain Inventory, Douleur Neuropathique 4 and McGill Pain Questionnaire instruments. Results: The sample was predominantly composed of males (93.5%), under the age of 30 years (58.0%), who were injured mainly in motorcycle accidents (77.4%). The prevalence of myofascial pain was 38.7%. The muscles on the injured side were more affected than those on the non-injured side. Interpretation: This study suggests that there may be myofascial components involved in pain of patients with BPI.
Objective To describe management strategies used in public emergency departments in a middle-income country for patients with acute non-specific low back pain. Design A descriptive, cross-sectional analysis of baseline data from a prospective cohort study. Setting and participants A study with 600 patients with low back pain presenting in four public emergency departments from São Paulo, Brazil was conducted. Outcome measures Diagnostic tests, pharmacological interventions, and/or referral to other healthcare professionals were collected. Descriptive analyses were used to report all outcomes. Results Of all patients, 12.5% (n=75) underwent some diagnostic imaging tests. Medication was administered to 94.7% (n=568) of patients. The most common medications were non-steroidal anti-inflammatory drugs (71.3%; n=428), opioids (29%; n=174) and corticosteroids (22.5%; n=135). Only 7.5% (n=45) of patients were referred to another type of care. Conclusion There is a need for research data on low back pain from middle-income countries. There was an acceptable rate of prescription for diagnostic imaging tests. However, there were high medication prescriptions and small rates of referrals to other healthcare services. Our findings indicate that there is still a need to implement best practices in the management of acute low back pain at public emergency departments in Brazil.
Low back pain (LBP) is one of the largest and most frequent public health problems worldwide. Photobiomodulation therapy (PBMT) is a frequently used non-pharmacological therapy for the treatment of musculoskeletal disorders. However, there is little high-quality scientific evidence that demonstrates the effectiveness of PBMT in the treatment of patients with chronic LBP in the short, medium and long term. Therefore, the objective of this clinical trial is to evaluate the effects of PBMT in patients with chronic non-specific LBP in the short, medium and long term.
The aim of this study was to investigate and identify the articles published in national journals that applied normality tests, which are the most used, if there is any relation with the Qualis and there over the years an increase in the use of these tests.For doing this research three national journals indexed in SciELO were chosen.Publications between 2008 and 2012 were analyzed.A descriptive analysis was performed in Excel 2007 and normality test (Shapiro Wilk) by SPSS, as well as the comparison between groups (ANOVA one-way), with significance level of 5%.Among all of the original articles (n=871), it was observed that 358 mentioned the use of normality test.Thus, it can be stated that the Brazilian Journal of Physical Therapy is responsible for 46% of these publications.Physical Therapy and Research and Physical Therapy in Movement account for 30.2% and 23.7% of publications, respectively.Statistical tests were most used Shapiro-Wilk (n=163) and Komolgorov-Smirnov (n=137).These accounted for 83.8% of the publications cited test the normality of your data.Even more, other tests performed 2.8% and 13.4% did not specify which test is used, however, said test normality.It is concluded that the national journal of higher Qualis, Brazilian Journal of Physical Therapy, has more strict criteria in relation to statistical analysis and Colloquium Vitae, jan/abr 2014 6(1): 01-10.
