Background: Psychosocial factors are not routinely identified in physical therapy assessments, although they can influence the prognosis of patients with low back pain. The "STarT Back Screening Tool" (SBST) questionnaire aids in screening such patients for poor prognosis in the primary care setting and classifies them as high, medium, or low risk based on physical and psychosocial factors. Objectives: This study sought to translate and cross-culturally adapt the SBST to the Brazilian Portuguese language and test the reliability of the Brazilian version. Method: The first stage of the study consisted of the translation, synthesis, and back-translation of the original version of the STSB, including revision by the Translation Group, pretest of the translated version, and assessment by an expert panel. The pre-final Brazilian version was applied to 2 samples comprising 52 patients with low back pain; these patients were of both genders and older than 18 years of age. To assess the instrument's reliability, an additional sample comprising 50 patients was subjected to 2 interviews, and the results were assessed using the quadratic weighted kappa value. The instrument's internal consistency was assessed using Cronbach's alpha (n=105), and the standard error of measurement was also calculated (n=50). Results: Translation and back-translation attained consensus, and only item 6 required changes; the reformulated version was applied to an additional sample comprising 52 individuals who did not report any doubts related to this item. The reliability of the SBST-Brazil was 0.79 (95% confidence interval: 0.63-0.95), the internal consistency was 0.74 for the total score and 0.72 for the psychosocial subscale, and the standard error of measurement was 1.9%. Conclusion: The translated and cross-culturally adapted SBST-Brazil proved to be reliable for screening patients according to their risk of poor prognosis and the presence of psychosocial factors.

HighlightsThe set of tests presented good reliability for the lumbopelvic region.Reference values may contribute for clinical practice assessments.SEM, TEM and MDC values confirm the set of tests’ usage in clinical practice.

Objective: To retrospectively survey the most frequent complications from medial opening wedge high-tibial osteotomy. This procedure is becoming increasingly important in treating knee arthrosis, as one of the options for young and active patients. Despite satisfactory results and its benefits, it is not a complication-free procedure. Methods: All cases of medial opening wedge high-tibial osteotomy above the tibial tubercle with fixation using a Puddu plate that were performed at the Celso Pierro Hospital and Maternity Hospital, Pontifical Catholic University of Campinas (PUC-Campinas) and the Wilson Mello Institute, Campinas, between October 1, 1987, and October 30, 2008, were evaluated retrospectively. Patients with less than 12 months of follow-up or incomplete medical files, and those who underwent bilateral osteotomy, were excluded. Results: Out of the 67 cases evaluated, 55 were males and 12 were females, with a mean age of 49.5 years. The mean wedge size was 10.15 mm and the most common complications were moderate to severe pain (13.04%), stiffness (6.52%), material breakage (4.4%), intraoperative fracture of the lateral cortical bone (4.4%) and infection (4.4%). It was observed that patients with delayed consolidation of the osteotomy had a greater chance of presenting complications (p < 0.05). Conclusion: Complications from medial wedge osteotomy are more frequent when associated with delayed consolidation.

Highlights•SBST-Brazil showed a moderate to good correlation with disability tools.•SBST-Brazil demonstrated weak correlations with fear-avoidance beliefs.•SBST-Brazil discriminates LBP patients with disability and fear-avoidance beliefs.

Study Design. Cross-sectional study. Objective. We explored the differences between chronic low back pain (CLBP) patients suited for the functional optimization approach and healthy controls in isometric hip-strength and lumbar-endurance tests and determined classificatory cutoff values for strength and endurance tests and ratios. Summary of Background Data. To optimize the treatment effect for CLBP, some approaches have classified patients into homogeneous subgroups matched to specific treatments. We evaluated CLBP patients suited for the functional optimization approach, who seek care because they experience symptoms during activities with high physical demands, although they are relatively asymptomatic. Methods. Three hundred fifty subjects (healthy controls, 170; CLBP patients, 180) were stratified by age (18–40 and 41–65 yrs), sex, and physical activity level. The CLBP patients had an Oswestry Disability Index score < 20% and a Numeric Pain Rating Scale score < 3. The subjects underwent hip abductor, extensor, and flexor isometric strength tests; a deep abdominal function test; and lateral/frontal bridge and lumbar flexor/extensor endurance tests. Results. Relative to the healthy controls, the CLBP patients showed significantly (P > 0.05) higher strength scores in the hip flexor and deep abdominal function tests but lower endurance in the lateral and frontal bridge and lumbar flexor and extensor tests. The cutoff values of the lumbar flexor test and the lumbar flexor/extensor, lateral bridge/lumbar flexor, frontal bridge/lumbar flexor, and hip extensor/flexor test ratios showed acceptable accuracy (AUC = 0.84, 0.82, 0.79, 0.75, and 0.73, respectively). Conclusion. In lumbopelvic and hip-performance tests, CLBP patients suited for the functional optimization approach showed differences from healthy controls. These patients could be discriminated from healthy controls on the basis of accurate cutoff values for strength and endurance tests and ratios, which should be considered in treatment decision-making when patients need to return to activities with higher physical demands. Level of Evidence: 2

The current study suggests a functional profile for subjects who are scheduled to undergo TKA. Our results show that the correlations of self-report and performance-based measures of function and reported pain are poor. This enhances the idea of using all of these types of measures to establish the functional profile a sample of subjects with advanced KOA. Copyright © 2015 John Wiley & Sons, Ltd.

Objetivo: Analisar a correlação entre os déficits musculares dos extensores e flexores do joelho através do pico de torque isocinético com os testes de salto monopodal, frouxidão ligamentar pós-operatória e questionário de função em indivíduos normais e indivíduos submetidos à reconstrução do LCA com enxerto autólogo do tendão patelar e dos tendões flexores. Métodos: Foram recrutados 60 indivíduos, formando três grupos: 20 indivíduos sem lesões no joelho (grupo GC) e dois grupos de 20 indivíduos submetidos à reconstrução do LCA com tendão patelar (grupo GTP) ou tendões flexores (grupo GTF). Resultados: Os resultados demonstraram correlação significativa entre déficits no pico de torque e testes funcionais no torque extensor nos grupos GTF e GC. Não foram observadas correlações significativas entre frouxidão ligamentar pós-operatória e questionário de Lysholm com os testes de salto e déficits no pico de torque. Em relação à diferença entre os grupos, foi observado que o grupo GTP demonstrou maior déficit do torque extensor, menor pontuação no questionário de Lysholm e maior percentagem dos indivíduos com índice de simetria entre membros (ISM) < 90% em ambos os testes de salto monopodal quando comparado com os demais grupos. Conclusão: Na avaliação funcional de pacientes submetidos à reconstrução do LCA, não é aconselhável a utilização de apenas um instrumento de medida, porque a correlação significativa entre déficit no pico de torque, questionários de função, frouxidão ligamentar e testes de salto não é encontrada em todos os grupos testados.
