Abstract Background and objectives: Neuropathic pain is common in the general population worldwide and Brazil. The painDETECT questionnaire is a notable instrument for screening on neuropathic pain. A Brazilian version of the painDETECT is necessary to broaden the possibilities of identification of neuropathic pain in the Brazilian population for the proper diagnosis and treatment. The current study aimed to perform the translation and cross-cultural adaptation of the painDETECT into the Portuguese language of Brazil. Methods: A cross-cultural adaptation study was conducted in 11 stages according to standard procedures. Descriptive statistics were performed. The internal consistency of the questionnaire was assessed using Cronbach’s Alpha test (α). Results: Four translators, 10 experts, and 30 patients participated in the study. The expert committee adapted five out of nine items (item 2, 3, 6, 8, and 10) to the Brazilian context. The pretesting phase showed good internal consistency (α = 0.74) for the nine items, including the pain pattern and the body chart domains. The Cronbach’s α of the instrument with seven descriptor items of pain was 0.83. Conclusions: The painDETECT was cross-culturally adapted into a Brazilian context and can be used to identify neuropathic components in pain of Brazilian patients. Clinical implications: PainDETECT is available for Brazilians to identify neuropathic components in pain.

RESUMO Independentemente da natureza dos acidentes que ocorrem diariamente, as consequências frequentemente exigem reabilitação especializada. Este estudo pretende verificar qual setor de fisioterapia ambulatorial de um instituto de ortopedia e traumatologia apresenta maior prevalência de fichas de encaminhamento para atendimento. Além disso, pretende verificar qual gênero predomina e qual é a relação entre as faixas etárias e os setores de fisioterapia ambulatorial de um hospital de referência da cidade de São Paulo. Trata-se de um estudo prospectivo realizado entre março e dezembro de 2016 com uma amostra de 1507 fichas de encaminhamento ao Ambulatório de Fisioterapia do Instituto de Ortopedia e Traumatologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. O estudo mostrou que o setor Trauma em Fisioterapia Ambulatorial apresenta maior quantidade de fichas de encaminhamento, que o gênero masculino foi predominante e que há uma correspondência das relações entre diferentes faixas etárias e os setores de Fisioterapia Ambulatorial.

ABSTRACT Regardless of the nature of accidents that occur daily, the consequences often require specialized rehabilitation. This study aims to verify which outpatient physical therapy sector of an orthopedics and traumatology institute has the highest prevalence of referral forms for care. In addition, it verifies which gender predominates and what is the relationship between age groups and the outpatient physical therapy sectors of a reference hospital in the municipality of São Paulo. This is a prospective study conducted between March and December 2016 with a sample of 1507 referral forms to the Physical Therapy Outpatient Clinic of the Institute of Orthopedics and Traumatology, Clinical Hospital of the Medicine School of University of São Paulo. The study showed that the Trauma sector for Outpatient Physical Therapy has a higher number of referral forms, the male gender was predominant, and the different age groups corresponded to each Outpatient Physical Therapy sectors.

RESUMEN Independientemente de la naturaleza de los accidentes que ocurren a diario, las consecuencias a menudo requieren rehabilitación especializada. Este estudio tiene como objetivo verificar qué sector de fisioterapia ambulatorio de un instituto de ortopedia y traumatología tiene la mayor prevalencia de formularios de derivación para la atención. Además, tiene la intención de verificar qué género predomina y cuál es la relación entre los grupos de edad y los sectores de fisioterapia para pacientes ambulatorios de un hospital de referencia en la ciudad de São Paulo. Este es un estudio prospectivo realizado entre marzo y diciembre de 2016 con una muestra de 1507 formularios de derivación a la Clínica Ambulatoria de Fisioterapia del Instituto de Ortopedia y Traumatología de la Facultad de Medicina de la Universidad de São Paulo, Hospital das Clínicas. El estudio mostró que el sector de Trauma en Fisioterapia Ambulatoria tiene un mayor número de formas de derivación, que predomina el género masculino y que existe una correspondencia entre las relaciones entre los diferentes grupos de edad y los sectores de Fisioterapia Ambulatoria.

Abstract Aims: The purpose of this study was to test an experimental fatigue protocol for the knee joint extensor muscles performed on an isokinetic dynamometer. Method: SPIRIT recommendations were applied. Participants were 40 healthy, young men and women. Protocol: The pre-fatigue quadriceps femoris peak torque during concentric maximum voluntary contractions (MVC) at 60º/s was measured. During the first protocol part, the task was to do MVC at 60°/s until a sequence of five concentric MVC was below 40% of its initial value. For the second part, intermittent quadriceps femoris muscle and hamstrings maximum voluntary isometric contractions for 30 s (ratio 2/1 seconds). Thirty seconds after the isometric MVC (post-fatigue), they did three concentric MVC. Then, after 5 minutes of absolute rest, they did two concentric MVC. Men and women showed a lower peak torque due to this protocol (p < 0.001). Conclusion: This protocol was effective for fatigue men and women’s quadriceps femoris muscle.
