Dolor sacroilíaco: revisión actualizada del enfrentamiento diagnóstico / Sacroiliac joint pain: an updated review of the clinical approach for diagnosis

El dolor sacroilíaco es responsable de 15% a 30% de los cuadros de dolor lumbar bajo. El diagnóstico de esta patología es un desafío para el médico, debido a su compleja anatomía, el amplio diagnóstico diferencial, y las diversas etiologías que pueden provocar dolor en la articulación sacroilíaca. Una anamnesis ordenada y dirigida, asociada a un examen físico preciso, ayuda a orientar el diagnóstico. Las pruebas sacroiliacas específicas deben realizarse en aquellos pacientes con sospecha de dolor sacroilíaco, y deben interpretarse en conjunto y no de manera aislada. La resonancia magnética sirve para descartar otras causas de dolor lumbar bajo o diagnosticar casos de sacroileítis inflamatoria. La infiltración de la articulación es el gold standard para el diagnóstico, y debe realizarse en pacientes con alta sospecha de dolor sacroilíaco, por la anamnesis, examen físico, y tres o más pruebas sacroilíacas específicas positivas.

Sacroiliac pain accounts for 15% to 30% of low back pain conditions. Its diagnosis is a challenge for the physician due to its complex anatomy, the wide differential diagnoses list, and its several causes. Diagnosis requires a structured clinical history and an accurate physical examination. Specific sacroiliac physical examination tests should be performed in patients with suspected sacroiliac joint pain and interpreted together, not in isolation. Magnetic resonance imaging can rule out other causes of low back pain or diagnose inflammatory sacroiliitis. Joint infiltration is the gold standard for diagnosis, and it should be performed in patients with a high suspicion of sacroiliac joint pain based on anamnesis, physical examination, and three or more positive specific sacroiliac tests.

Structural validity of the Japanese Orthopedic Association back pain evaluation questionnaire in individuals with chronic low back pain

SUMMARY OBJECTIVE: The main aim of this study was to evaluate the structural validity of the Brazilian version of the Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ). METHODS: Individuals with chronic low back pain were included. The data collection of the study occurred by means of online platform. Confirmatory factor analysis was performed. The theoretical version proposed for the JOABPEQ with five domains was tested. The following indices were considered to verify the fit of the model: comparative fit index (CFI), Tucker-Lewis index (TLI), root mean square error of approximation (RMSEA), and chi-square/degrees of freedom (DF). RESULTS: The final sample consisted of 175 volunteers, mostly women (68%), adults (mean age of 28.98 years), lean (mean body mass index of 25 kg/m2), with incomplete higher education, single, with mean of pain chronicity of 61.50 months and mean of pain intensity of 6.78 points on the Numeric Pain Scale. Regarding the structure of the JOABPEQ, the original version with five domains was adequate: chi-square/DF=1.52, CFI=0.954, TLI=0.948, and RMSEA=0.055. The factorial load ranges from 0.41 to 0.90. CONCLUSIONS: This study confirms the structure of JOABPEQ with 5 domains (low back pain, lumbar function, walking ability, social life function, and mental health) and 25 items in individuals with chronic low back pain.

Resultados de una cohorte de pacientes tratados con osteopatía en un hospital polivalente / Results of a cohort of patients treated with osteopathy in a polivalent hospital

Introducción: la osteopatía aborda al paciente de manera global y aplica técnicas de tratamiento manual. Se realizó una evaluación retrospectiva sobre 447 pacientes para conocer los resultados del tratamiento del dolor lumbar y cervical. Material y métodos: fueron incluidos en este estudio 447 pacientes con diagnóstico de lumbalgia y cervicalgia (77,4% de sexo femenino). Los pacientes atendidos ya habían realizado tratamientos convencionales sin haber conseguido resultados satisfactorios. Se evaluó a los pacientes con la escala de valor numérico de dolor (EVN), y los puntajes (scores) de Oswestry (ODI) y el índice de discapacidad de la región cervical (NDI). Los 4 osteópatas intervinientes son profesionales certificados en esta disciplina. Resultados: el 42,8% de los pacientes fueron derivados por el Servicio de Traumatología y el 41,3% por el Servicio de Medicina Familiar. El 34,2% tuvieron diagnóstico de dolor lumbar y al 20,81% se le diagnosticó dolor cervical. Tanto en la valoración del dolor como en los scores utilizados se encontraron diferencias estadísticamente significativas entre la primera y la última sesión. Discusión: en pacientes con diagnóstico de lumbalgia y cervicalgia que no habían obtenido resultados satisfactorios con tratamientos convencionales previos, el tratamiento osteopático derivó en mejoras significativas en todos los parámetros estudiados. (AU)

Introduction: osteopathy addresses the patient globally and applies manual treatment techniques. A retrospective evaluation was carried out on 447 patients to know the results of the treatment of lumbar and cervical pain. Material and methods: 447 patients with a diagnosis of low back pain and cervical pain (77.4% female) were included in this study. The patients already had undergone conventional treatments without having achieved satisfactory results. The patients were evaluated with the numerical value of pain scale (VNS), and Oswestry scores (ODI) and the index of disability of the cervical region (NDI). The 4 intervening osteopaths are certified professionals in this discipline. Results: 42.8% of the patients were referred by the Traumatology Service and 41.3% by the Family Medicine Service. 34.2% had a diagnosis of lumbar pain and 20.8% were diagnosed with neck pain. Statistically significant differences were found between the first and last sessions in both the pain assessment and the scores used. Discussion: in patients with low back pain and neck pain who had not obtained satisfactory results with previous conventional treatments, osteopathic treatment resulted in significant improvements in all the parameters evaluated.

The effect of kinesiophobia in older people with acute low back pain: longitudinal data from Back Complaints in the Elders (BACE) / O efeito da cinesiofobia em idosos com dor lombar aguda: dados longitudinais do estudo Back Complaints in the Elders (BACE) / El efecto de la quinesofobia en personas mayores con dolor lumbar agudo: datos longitudinales de Back Complaints in the Elders (BACE)

Abstract: This study aimed to investigate the course of low back pain (LBP) intensity over a period of 12 months in older people with and without kinesiophobia.This was an international multicenter study. LBP intensity was examined by using the Numerical Pain Scale at baseline and over five follow-up periods. The Fear-Avoidance Beliefs Questionnaire was used to measure patients' beliefs and fears. The study included 532 older adults (non kinesiophobic = 227; kinesiophobic = 305). The individuals had moderate pain at baseline, with a significant difference observed between the groups. Participants showed a rapid improvement in the first 6 weeks, followed by minor improvements in the succeeding months. However, a significant difference between groups remained during the follow-up period. Independently, kinesiophobia is a significant prognostic factor. These findings suggest the importance of screening for psychosocial factors in the management of older patients with LBP. Practice implications: patients need to be warned that pain can be perpetuated by inappropriate avoidance behaviors that may later lead to disability.

Resumo: O estudo teve como objetivo investigar a evolução da intensidade da dor lombar (DL) ao longo de 12 meses em idosos com e sem cinesiofobia. Este foi um estudo multicêntrico internacional. A intensidade da DL foi avaliada com a Numerical Pain Scale na linha de base e ao longo de 5 períodos de seguimento. As crenças e os medos dos pacientes foram medidos com o Fear-Avoidance Beliefs Questionnaire. O estudo incluiu 532 idosos (sem cinesiofobia = 227; com cinesiofobia = 305). Os idosos apresentavam dor moderada na linha de base, com uma diferença significativa entre os grupos. Os participantes mostraram melhora rápida nas primeiras seis semanas, seguida por melhoras menores nos meses seguintes. Entretanto, persistiu uma diferença significativa entre os grupos durante o período de seguimento. A cinesiofobia é um fator prognóstico importante e independente. Os achados sugerem a importância da triagem de fatores psicossociais no manejo de pacientes idosos com DL. Implicações práticas: os pacientes devem ser advertidos que a dor pode ser perpetuada por comportamentos inadequados de evitação, podendo à incapacidade no longo prazo.

Resumen: El objetivo fue investigar el curso de la intensidad del dolor lumbar (LBP), durante un período de 12 meses, en personas ancianas con y sin quinesofobia. Se trata de un estudio multicéntrico internacional. La intensidad del LBP se evaluó usando la Escala Numérica de Dolor en una base de referencia y sobre 5 períodos de seguimiento. Con el fin de medir las creencias y temores de los pacientes, usamos el Fear-Avoidance Beliefs Questionnaire. El estudio incluyó a 532 ancianos (no quinesofóbicos = 227; quinesofóbicos = 305). Los ancianos sufrieron un dolor moderado en la base de referencia, con una significativa diferencia observada entre grupos. Los participantes mostraron una rápida mejora durante las 6 primeras semanas, seguidas por mejoras menores en los meses siguientes. No obstante, se mantuvo una diferencia significativa entre grupos durante el período de seguimiento. Independientemente, la quinesofobia es un factor pronóstico importante. Estos resultados sugieren la importancia de monitorear factores psicosociales en la gestión de pacientes ancianos con LBP. Implicaciones clínicas: los pacientes necesitan ser avisados de que el dolor puede perpetuarse por comportamientos inapropiados de prevención que quizás más tarde conduzcan a la discapacidad.

Dolor lumbar en niños / Low back pain in children

El dolor lumbar en niños ha ido en aumento en su prevalencia en los últimos años. Si bien la causa del dolor lumbar generalmente se relaciona con alguna condición que resuelve espontáneamente, o a períodos de desarrollo y crecimiento acelerado, se deben descartar una serie de patologías presentes en este rango etario que conllevan severas implicancias para la adultez. Se ha constatado que la incidencia del dolor lumbar aumenta a lo largo de los años de vida del niño, y se espera que al llegar a la adolescencia, un 10-30% de la población pediátrica total haya experimentado dolor lumbar en algún momento de su vida. A pesar de la creciente incidencia, un estudio prospectivo en niños con dolor lumbar reveló, que menos de un 30% de los pacientes tuvo un diagnóstico definitivo, o con una etiología clara. Dentro del estudio del dolor lumbar son esenciales una historia clínica detallada, con caracterización del dolor, y presencia de banderas rojas. El examen físico debe ser completo, y en caso de hallazgos positivos, debe complementarse con estudio imagenológico. Hay que considerar que un gran porcentaje de los pacientes presentarán un dolor lumbar de carácter inespecífico atribuible a tensión muscular y factores psicosociales. Sin embargo, debe realizarse un seguimiento adecuado hasta la resolución sintomática. El estudio debe ir dirigido a descartar aquellas patologías de mayor complejidad, teniendo en consideración los factores de riesgo asociados: edad, actividad física, peso, factores psicosociales, entre otros. La radiografía nos orientará y ayudará a descartar la mayoría de las patologías prevalentes en este grupo etario, profundizando en el estudio, dependiendo de los hallazgos clínicos y de la anamnesis.

Lumbar pain in children has increased in frequency during the last years. Even though the primary cause for this pain is related to benign conditions, or accelerated bursts of growth, there are certain pathologies to be discarded since they can have an impact during adulthood. The incidence of lumbar pain increases with age, and it has been reported that by the time of adolescence up to 10 to 30% of the pediatric population will have experimented lumbar pain at some point in their lives. In spite of this increasing incidence, a report revealed that less than 30% of patients had a definitive diagnosis, o a clear etiology. It is of importance, during the study of lumbar pain, to have a good clinical history, characterization of pain, and thorough physical examination, and in the case of positive findings, an imagenology study must be completed. We have to consider that a large percentage of patients will experience unspecific lumbar pain, probably caused by muscle contraction and psychosocial factors. Nevertheless, close follow up must be made until the symptoms are resolved. The study must be directed at diseases that are more complex, considering the risk factors associated: age, physical activity, weight, psychosocial factors, among others. Radiography will help to guide the study and rule out the most prevalent pathology, according to the history and clinical findings.

Lombalgia em equinos de vaquejada: achados clínicos, ultrassonográficos e resultados terapêuticos de 25 casos / Back pain in vaquejada horses: clinical, ultrasound findings and therapeutic outcome in 25 cases

Vinte e cinco equinos da raça Quarto de Milha, em atividade esportiva na modalidade de vaquejada no estado do Rio Grande do Norte, Brasil, 15 machos e 10 fêmeas, com idade média de 7,91 + 3,26 anos, foram examinados na propriedade de origem ou centro de treinamento para diagnóstico de baixo desempenho associado a dor lombar. O exame clínico da região toracolombar foi realizado por meio da inspeção, palpação, ultrasonografia, testes de mobilização (ventro e dorsoflexão toracolombar; flexão lateral e rotação toracolombar; flexão lateral e rotação cervical e torácica) além de análise do animal em movimento. As principais alterações encontradas foram miosite epaxial, desmite supra-espinhosa, além de atrofia do músculo multifidus. O tratamento clínico consistiu na administração de injeções periespinhais de Acetonida de triancinolona numa dose total de 200mg, além de exercício controlado. Após o tratamento, todos os animais retornaram a desempenhar suas atividades atlética em nível de desempenho superior ou igual ao demonstrado antes do diagnóstico e tratamento da lombalgia.

Twenty five horses of the Quarter horse breed, in sporting activity in the vaquejada modality in the state of Rio Grande do Norte, Brazil, 15 males and 10 females, with an average age of 7.91 + 3.26 years, were examined in the property of origin or training center for low performance diagnosis associated with low back pain. The clinical examination of the thoracolumbar region was performed through inspection, palpation, ultrasonography, mobilization tests (ventral and thoracolumbar dorsoflexion; lateral flexion and thoracolumbar rotation; lateral flexion and cervical and thoracic rotation) in addition to analysis of the animal in motion. The main changes found were epaxial myositis, supraspinatus desmite, as well as atrophy of the multifidus muscle. Clinical treatment consisted of administering perispinal injections of triamcinolone Acetonide in a total dose of 200mg, in addition to controlled exercise. After treatment, all animals returned to performing their athletic activities at a performance level greater than or equal to that demonstrated before the diagnosis and treatment of low back pain.

Cross-cultural adaptation, validity and reproducibility of the Back Beliefs Questionnaire among older Brazilians with acute low back pain. A cross-sectional study

ABSTRACT BACKGROUND: Low back pain (LBP) has emerging as an epidemic, multifactorial and multidimensional condition in older age. Assessment of attitudes and beliefs of patients with back pain is necessary for understanding the impact of psychosocial factors on pain perception and management. OBJECTIVES: To cross-culturally adapt and examine the validity and reproducibility (intra and interrater reliability and agreement) of the Back Beliefs Questionnaire (BBQ) in older Brazilians with acute LBP. DESIGN AND SETTING: Cross-sectional methodological report conducted at the Department of Physical Therapy of the Universidade Federal de Minas Gerais, Belo Horizonte, Brazil. METHODS: The present study was conducted for translating, adapting, and examining the psychometric properties of a questionnaire. Participants aged ≥ 60 years experiencing an acute episode of LBP were recruited. Coefficients of internal consistency, reliability and agreement were obtained using Cronbach's α, intraclass correlations, and standard error of measurement and the smallest detectable change, respectively. RESULTS: Twenty-six participants aged between 60-84 years and reporting a mean of 9.8 (4.3) years of schooling completed the study. The Brazilian Portuguese-language version of the BBQ (BBQ-Brazil) was proposed and presented with adequate conceptual, semantic, operational, and measurement equivalence from the original version. Intra and interrater evaluations showed moderate (0.74) and excellent (0.91) intraclass correlation coefficients, respectively, with small standard error of measurement for both evaluations. Internal consistency was considered adequate (0.70). CONCLUSION: BBQ-Brazil had consistent measurements of validity and reproducibility, and proved to be a valuable tool in clinical practice for addressing attitudes and beliefs of older patients with acute LBP.

Hernia lumbar del espacio de Grynfelt. A propósito de un caso / Lumbar hernia of the Grynfelt space. Apropos of a case

RESUMEN La hernia lumbar del espacio de Grynfelt, pese a que es la más frecuente de los dos tipos de hernias lumbares, es un defecto raro de la pared abdominal posterior. Su diagnóstico se hace difícil por su relativa poca frecuencia. Los médicos no piensan seriamente en esta variedad de hernia, aunque constituye una patología en la que el diagnóstico, al igual que el resto de las hernias de la pared abdominal, es esencialmente clínico. Se presentó un caso tipo de hernia poco frecuente. Una paciente de 32 años con antecedentes de salud, que hacía 3 meses comenzó a quejarse de dolor en la región lumbar y notó la presencia de una masa pequeña en esa misma región. Acudió a la consulta de Cirugía por este motivo y posterior a los estudios correspondientes se le realizó hernioplastia lumbar (AU).

ABSTRACT Lumbar hernia of the Grynfelt space, although it is the most frequent of the two kinds of lumbar hernias, is a rare posterior abdominal wall defect. Its diagnosis is difficult because of its low frequency. Doctors do not think about this illness because it is very infrequent, though it is a disease that, like the rest of abdominal wall hernia, is mainly clinically diagnosed. The authors presented a typically infrequent case of hernia. A female patient, aged 32 years, with health antecedents, referred that three months ago she began to feel pain in the lumbar region and noticed the presence of a little mass in that region. For that reason she assisted the consultation of Surgery and, after being correspondently studied, she underwent a lumbar hernioplasty (AU).

Diagnóstico de espondiloartrite axial em pacientes com fibromialgia / Axial spondyloarthritis diagnosis in fibromyalgia patients

Objetivo: Avaliar pacientes com fibromialgia e dor lombar, bus- cando características clínicas de espondiloatrites axiais. Méto- dos: Neste estudo transversal, cem pacientes com fibromialgia e idades entre 18 e 65 anos foram avaliados. A avaliação consis- tiu em um questionário baseado no braço clínico dos critérios Assessment of Spondyloarthritis International Society para diag- nóstico de espondiloatrites axiais e um questionário de impacto da fibromialgia (Revised Fibromyalgia Impact Questionnaire). Re- sultados: Quando o braço clínico da Assessment of Spondyloar- thritis International Society foi aplicado em pacientes com fibro- mialgia e dor lombar, 80% dos pacientes preencheram os critérios para diagnóstico de espondiloatrites axiais. As principais carac- terísticas de espondiloatrite axial foram dor lombar inflamatória, boa resposta a drogas anti-inflmatórias não esteroidais, artrite e entesite. Pacientes com critérios de espondiloatrites axiais posi- tivos apresentaram maiores níveis séricos de proteína C-reativa (p=0,00035). O valor médio do Revised Fibromyalgia Impact Ques- tionnaire para todos os pacientes avaliados foi 63,6, e não houve di- ferença entre os pacientes que preencheram os critérios e aqueles que não preencheram. Conclusão: Pacientes com fibromialgia e dor lombar frequentemente apresentam características clínicas de espondiloatrite axial, e aqueles que preencheram os crité- rios clínicos para espondiloatrites axiais também apresentaram maiores níveis séricos de proteína C-reativa.

Objective: To evaluate patients with fibromyalgia and back pain for clinical features of axial spondyloarthritis. Methods: In this cross-sectional study, one hundred fibromyalgia patients between 18 and 65 years old were assessed. The assessment consisted of a questionnaire based on the clinical arm ofthe Assessment of Spondyloarthritis International Society criteria for the diagnosis of axial spondyloarthritis and a questionnaire on the impact of fibromyalgia (Revised Fibromyalgia Impact Questionnaire). Re- sults: When the clinical arm of the Assessment of Spondyloarthri- tis International Society was applied in patients with fibromyal- gia and back pain, 80% of the patients met the clinical criteria for diagnosis of axial spondyloarthritis. The main features of axial spondyloarthritis in fibromyalgia patients were inflammatory back pain, good response to non-steroidal anti-inflammatory drugs (NSAIDs), arthritis, and enthesitis. Patients with positive axial spondyloarthritis criteria presented with higher C- reac- tive protein levels (p=0.00035). The mean value of the Revised Fibromyalgia Impact Questionnaire for all patients assessed was 63.6 and there was no difference between patients that met the criteria for axial spondyloarthritis and those who did not. Con- clusion: Patients with fibromyalgia and back pain often present clinical features of axial spondyloarthritis, and those who met the clinical criteria for axial spondyloarthritis also presented with higher levels of C-reactive protein.

Dolor sacroilíaco: epidemiología, fisiopatología, diagnóstico y tratamiento / Sacroiliac pain: epidemiology, physiopathology, diagnosis and treatment

El dolor sacroilíaco es una causa generalmente subdiagnosticada de dolor lumbar, que afecta del 15% a 30% de los pacientes con dolor lumbar bajo crónico no radicular. La articulación sacroilíaca (ASI) recibe continuo stress durante la bipedestación y marcha, siendo estabilizada por estructuras ligamentarias, capsulares y miofasciales fuertes, que reciben una abundante inervación. Destaca la dificultad en el diagnóstico del dolor sacroilíaco; debido a su naturaleza heterogénea. Éste se debe sospechar en todo paciente con síndrome de dolor lumbar no radicular, unilateral y no central. El examen físico debería descartar patología de cadera y columna lumbar. La realización de maniobras de provocación del dolor sacroilíaco aporta en el diagnóstico, teniendo la combinación de 3 o más maniobras positivas una sensibilidad de 85% y especificidad de 79%. Se ha recurrido a inyecciones diagnósticas con anestésicos locales, tanto intraarticulares como de ligamentos circundantes. El tratamiento del dolor sacroilíaco es multimodal e individualizado para cada paciente. El tratamiento conservador­basado en terapia física y antiinflamatorios no esteroidales­ es la terapia de primera línea. Las infiltraciones esteroidales tanto intra como extraarticulares pueden proveer alivio en un grupo de pacientes con inflamación activa. La denervación de los ramos dorsales laterales con radiofrecuencia ha mostrado ser un tratamiento exitoso en pacientes con dolor sacroilíaco, logrando 6 meses a 1 año de alivio del dolor. En pacientes con dolor refractario, la fusión de la articulación sacroilíaca es una opción, prefiriéndose la técnica mínimamente invasiva de fijación trans-sacroilíaca.

Sacroiliac pain is an frecuent underdiagnosed source of low back pain, affecting 15% to 30% of individuals with chronic, non-radicular pain. The sacroiliac joint (SIJ) is subject to continuous stress during standing position and gait, being stabilized by strong ligament, capsular and myofascial structures with rich innervation. Due to its heterogeneous nature, SIJ pain is difficult to diagnose, and it should be suspected in all patients with non-radicular unilateral and non-central low back pain syndrome. Physical examination should rule out hip and lumbar spine pathology. SIJ provocation maneuvers are used for diagnosis, with the combination of 3 or more positive maneuvers resulting in a sensitivity of 85% and a specificity of 79%. Diagnostic injections of local anesthetics, both intra-articular and in the surrounding ligaments have been used. treatment of SIJ pain is multimodal and individualized for each patient. Conservative treatment, based on physical therapy and non-steroidal anti-inflammatory drugs (NSAIDs) is the first line therapy. Both intra- and extra-articular steroid infiltrations can provide relief in a group of patients with active inflammation. Radiofrequency denervation of lateral dorsal branches has proven to be a successful treatment in SIJ pain patients, achieving 6 to 12 months of pain relief. In patients with refractory pain, SIJ fusion is an option, with minimally invasive trans-sacroiliac fixation being the preferred technique.

The Brazilian version of the Bournemouth questionnaire for low back pain: translation and cultural adaptation

ABSTRACT BACKGROUND: The Bournemouth questionnaire is a multidimensional instrument for evaluating health domains among patients with low back pain. OBJECTIVE: The objective of this study was to translate and cross-culturally adapt the Bournemouth questionnaire for individuals with low back pain, to Brazilian Portuguese. DESIGN AND SETTINGS: This was a cross-sectional study conducted at the Federal University of São Carlos. METHODS: The Brazilian version of the Bournemouth questionnaire was developed following the processes of translation, back-translation, committee review and pre-testing. The translation phase involved two independent bilingual translators whose mother language was Brazilian Portuguese. The back-translation phase involved two independent translators whose mother language was English. In order to verify comprehension of the questionnaire, 44 individuals (43.1% men) with low back pain, and with mean age of 45.4 ± 13.8 years, participated in the pre-testing phase. RESULTS: During the translation phase, some terms and expressions were changed to obtain cultural equivalence to the original Bournemouth questionnaire. In the pre-testing phase, each item of the questionnaire showed a comprehension level of over 90%. CONCLUSION: The Bournemouth questionnaire was translated and culturally adapted to the Portuguese language, to be used among individuals with low back pain.

Diagnóstico de lumbalgia en estudiantes universitarios del área de salud en Tepic, Nayarit / Diagnosis of low back pain in university students in health department in Tepic, Nayarit

Resumen La lumbalgia es una sensación de dolor y malestar por debajo de la zona lumbar, ocasionando una discapacidad parcial o total. El objetivo de este estudio fue determinar la prevalencia de lumbalgia en estudiantes universitarios de Tepic Nayarit México. Se eligieron estudiantes de la Licenciatura en Nutrición y Fisioterapia, participando 90 los cuales 45 de cada profesión, quienes llenaron un cuestionario Nórdico de Kuorinka sobre padecimiento de lumbalgia relacionados con el tiempo que se encontraban en la escuela y sus actividades fuera de ella. El dolor de espalda prevaleció en los estudiantes de Nutrición (77.77%). La mala postura se adopta comúnmente en las clases. El 31.11% de los estudiantes de nutrición usan el respaldo de la butaca de manera ocasional y el 44.22% los de Fisioterapia lo utilizan de manera constante y ocasional. El 42.22% de los estudiantes tienen una posición normal al momento de escribir y el 33.33% en apoyo. Las posturas fueron un factor determinante para padecer el dolor lumbar en los estudiantes de ambas licenciaturas. La percepción dolorosa en la zona lumbar se debió por la malas medidas ergonomícas del mobiliario y las butacas no se contaban adaptadas a la complexión de la mayoría de los estudiantes.

Abstract Low back pain is a sensation of pain and discomfort below the lumbar area. This pain is caused by various factors causing a partial or total disability. The aim of the study is to determine the prevalence of low back pain in university students of Tepic Nayarit Mexico. It presents a study of prevalence of low back pain in students of the Nutrition physiotherapy. 90 students participated, 45 of each profession, who, after obtaining their informed consent, completed a questionnaire on the condition of low back pain related to the time found in the school and its activities outside it, based on the Kuorinka Nordic Questionnaire. Back pain prevailed in nutrition degree students (77.77%). Bad posture is commonly adopted in classes. The 31.11% of the nutrition degree students use the seat back occasionally, while the 44.22% of physiotherapy degree use it in a constant and occasional way. The 42.22% of students have a normal position at the time of writing and 33.33% in support. The postures were a determining factor for suffering lumbar pain. The students of the Nutrition degree and the Physiotherapy degree were prone to suffer it and most of them had a painful perception in the lumbar area, by the bad measures ergonomics of the furniture in the university and because they were not. They had seats adapted to the complexion, stature and manner of writing of most students.

Cross-cultural adaptation and reliability of the pain response to activity and position questionnaire

Abstract Background: The World Health Organization reports that one of the main incapacitating conditions in older adults is osteomusculoskeletal disorders, and among these is low back pain. There are few instruments translated and transculturally adapted with psychometric properties evaluated for older adults with this health condition in Brazil. The Pain Response to Activity and Positioning (PRAP) questionnaire enables classification of older adults through functional performance. The objective of this study was to perform a cross-cultural adaptation and verify the reliability of the PRAP for older Brazilian people with chronic low back pain. Methods: A cross-sectional methodological study from the international study "Back Complaints in the Elders". We included individuals aged ≥60 years, with chronic lumbar pain complaints lasting ≥3 months. The transcultural translation and adaptation process followed the criteria proposed by Beaton and Guilhemeim, 1993. Reliability was tested using an unweighted Cohen's Kappa. Results: Thirty-six (36) older adults participated in the study (71.15 ± 7.23 years, 94.4% female). The intra-rater reliability for Low Back Pain (LBP) was between 0.50-1.00 and 0.23-0.84 for lower limbs, while the inter-rater reliability for LBP was between 0.25-0.63 and between 0.18-0.53 for lower limbs. The criteria for low back pain diagnosis showed intra and inter-rater agreement of 0.52 and 0.47, respectively. Conclusion: The Brazilian version of the instrument showed adequate reliability and ability to classify older adults in the diagnosis of LBP by reporting the performance of daily activities, and is indicated for use in the context of research and clinical practice. Trial registration: There is no trial registration. This is a methodological study.

Chronic low back pain in patients with systemic lupus erythematosus: prevalence and predictors of back muscle strength and its correlation with disability / Lombalgia crônica em pacientes com lúpus eritematoso sistêmico: prevalência e preditores da força muscular de extensão de tronco e sua correlação com a incapacidade

Abstract Objective: To determine the prevalence of Chronic Low Back Pain and predictors of Back Muscle Strength in patients with Systemic Lupus Erythematosus. Methods: Cross-sectional study. Ninety-six ambulatory patients with lupus were selected by non-probability sampling and interviewed and tested during medical consultation. The outcomes measurements were: Point prevalence of chronic low back pain, Oswestry Disability Index, Tampa Scale of Kinesiophobia, Fatigue Severity Scale and maximal voluntary isometric contractions of handgrip and of the back muscles. Correlation coefficient and multiple linear regression were used in statistical analysis. Results: Of the 96 individuals interviewed, 25 had chronic low back pain, indicating a point prevalence of 26% (92% women). The correlation between the Oswestry Index and maximal voluntary isometric contraction of the back muscles was r = −0.4, 95% CI [−0.68; −0.01] and between the maximal voluntary isometric contraction of handgrip and of the back muscles was r = 0.72, 95% CI [0.51; 0.88]. The regression model presented the highest value of R 2 being observed when maximal voluntary isometric contraction of the back muscles was tested with five independent variables (63%). In this model handgrip strength was the only predictive variable (β = 0.61, p = 0.001). Conclusions: The prevalence of chronic low back pain in individuals with systemic lupus erythematosus was 26%. The maximal voluntary isometric contraction of the back muscles was 63% predicted by five variables of interest, however, only the handgrip strength was a statistically significant predictive variable. The maximal voluntary isometric contraction of the back muscles presented a linear relation directly proportional to handgrip and inversely proportional to Oswestry Index i.e. stronger back muscles are associated with lower disability scores.

Resumo Objetivo: Determinar a prevalência de lombalgia crônica (LBC) e os preditores de força muscular nas costas (FMC) em pacientes com lúpus eritematoso sistêmico (LES). Métodos: Estudo transversal. Selecionaram-se 96 pacientes ambulatoriais com LES por amostragem não probabilística, entrevistados e testados durante consultas médicas. As medidas de desfecho foram: prevalência ocasional de LBC, Índice de Incapacidade de Oswestry, Escala Tampa para Cinesiofobia, Escala de Gravidade da Fadiga e contrações isométricas voluntárias máximas (CIVM) de preensão manual e dos músculos das costas. Usaram-se o coeficiente de correlação e a regressão linear múltipla na análise estatística. Resultados: Dos 96 indivíduos entrevistados, 25 apresentavam LBC, o que indicou uma prevalência circunstancial de 26% (92% mulheres). A correlação entre o Índice de Incapacidade de Oswestry e a contração isométrica voluntária máxima dos músculos das costas foi de r = -0,4, IC 95% [-0,68; -0,01] e entre a CIVM de preensão manual e dos músculos das costas foi de r = 0,72, IC 95% [0,51; 0,88]. O modelo de regressão apresentou o maior valor de R2 observado quando a CIVM dos músculos das costas foi testada com cinco variáveis independentes (63%). Nesse modelo, a força de preensão manual foi a única variável preditiva (ß = 0,61, p = 0,001). Conclusões: A prevalência de LBC em indivíduos com LES foi de 26%. A CIVM dos músculos das costas foi 63% prevista por cinco variáveis de interesse. No entanto, apenas a força de preensão manual foi uma variável preditiva estatisticamente significativa. A CIVM dos músculos das costas apresentou uma relação linear diretamente proporcional à força de preensão manual e inversamente proporcional ao Índice de Incapacidade de Oswestry (ou seja, músculos das costas mais fortes estão associados a menores pontuações de incapacidade).

A rare case of centronuclear myopathy with DNM2 mutation: genotype­phenotype correlation

Centronuclear myopathy (CNM) is a group of rare genetic muscle disorders characterized by muscle fibers with centrally located nuclei. The most common forms of CNM have been attributed to X-linked recessive mutations in the MTM1 gene; autosomal-dominant mutations in the DNM2 gene-encoding dynamin-2, the BIN1 gene; and autosomal-recessive mutations in BIN1, RYR1, and TTN genes. Dominant CNM due to DNM2 mutations usually follows a mild clinical course with the onset in adolescence. Currently, around 35 mutations of the DNM2 gene have been identified in CNM; however, the underlying molecular mechanism of DNM2 mutation in the pathology of CNM remains elusive, and the standard clinical characteristics have not yet been defined. Here, we describe the case of a 17-year-old female who presented with proximal muscle weakness along with congenital anomalous pulmonary venous connection (which has not been described in previous cases of CNM), scoliosis, and lung disease without a significant family history. Her creatine kinase level was normal. Histology, special stains, and electron microscope findings on her skeletal muscle biopsy showed CNM with the characteristic features of a DNM2 mutation, which was later confirmed by next-generation sequencing. This case expands the known clinical and pathological findings of CNM with DNM2 gene mutation.
