Correlation between the Severity of the Lumbar Degenerative Disease and Sagittal Spinopelvic Alignment / Correlação entre a gravidade da doença degenerativa lombar e o alinhamento espinopélvico

Abstract Objective To evaluate the impact of the severity of lumbar degenerative disease (LDD) on sagittal spinopelvic alignment. Methods In total, 130 patients (mean age: 57 years; 75% female) with LDD-associated low-back pain were prospectively included. The severity of the LDD was defined by the following findings on anteroposterior and lateral lumbar spine radiographs: osteophytosis; loss of of height of the intervertebral disc; terminal vertebral plate sclerosis; number of affected segments; deformities; and objective instability. The disease was classified as follows: grade 0-absence of signs of LDD in the lumbar spine; grade I - signs of LDD in up to two segments; grade II - three or more segments involved; grade III - association with scoliosis, spondylolisthesis, or laterolisthesis. Spinopelvic radiographic parameters, including pelvic incidence (PI), lumbar lordosis (LL), discrepancy between the PI and LL (PI-LL), pelvic tilt (PT), and sagittal vertical axis (SVA), were analyzed according to the LDD grades. Results The radiographic parameters differed according to the LDD grades; grade-III patients presented higher SVA (p= 0.001) and PT (p= 0.0005) values, denoting greater anterior inclination of the trunk and pelvic retroversion when compared to grade-0 andgrade-I subjects. In addition, grade-III patients had higher PI-LL values, which indicates loss of PI-related lordosis, than grade-I subjects (p= 0.04). Conclusion Patients with more severe LDD tend to present greater spinopelvic sagittal misalignment compared to patients with a milder disease.

Resumo Objetivo Avaliar o impacto da graduação da doença degenerativa lombar (DDL) sobre o alinhamento sagital espinopélvico. Métodos Ao todo, 130 pacientes (dade média: 57 anos; 75% do sexo feminino) com dor lombar associada a DDL foram prospectivamente incluídos. A gravidade da DDL foi definida pelos seguintes achados nas radiografias anteroposterior e de perfil da coluna lombar: osteofitose; perda de altura do disco intervertebral; esclerose na placa vertebral terminal; número de segmentos afetados; deformidades; e instabilidade objetiva. Os pacientes foram graduados segundo a DDL da seguinte maneira: grau 0-ausência de sinais de DDL na coluna lombar; grau I - sinais de DDL em até dois segmentos; grau II - envolvimento em três ou mais segmentos; grau III - quando associada a escoliose, espondilolistese ou laterolistese. Parâmetros radiográficos espinopélvicos, como incidência pélvica (IP), lordose lombar (LL), discrepância entre a IP e a LL (IP-LL), versão pélvica (VP), e eixo vertical sagital (EVS) foram analisados de acordo com os graus de DDL. Resultados Houve diferença nos parâmetros radiográficos comparando-se os graus de DDL, com os pacientes de grau III apresentando maiores valores de EVS (p= 0,001) e VP (p= 0,0005), o que denota maior inclinação anterior do tronco e maior retroversão pélvica do que os pacientes de graus 0 e I. Pacientes de grau III também apresentaram maiores valores de IP-LL, o que denota perda da lordose relativa ao valor da IP, do que pacientes grau I (p= 0,04). Conclusão Pacientes com DDL mais grave demonstraram uma tendência a maior desalinhamento sagital espinopélvico comparados com pacientes com graus mais leves.

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.

Exercícios para tratamento de lombalgia inespecífica / Exercises for nonspecific low back pain treatment / Ejercicios para el tratamiento de la lumbalgia inespecífica

JUSTIFICATIVA E OBJETIVOS: A lombalgia é uma síndrome frequente e provoca incapacidade e perda no trabalho. Apesar de existirem diversas causas, o tipo de lombalgia mais frequente é a inespecífica. Os exercícios são frequentemente empregados para o tratamento da lombalgia porém existem controvérsias quanto a sua eficácia. O objetivo deste texto foi fazer uma revisão sobre exercícios para tratamento de lombalgia inespecífica. CONTEÚDO: Foram descritas a definição e a classificação das lombalgias. A incidência e os mecanismos da lombalgia inespecífica, e os exercícios empregados para seu tratamento foram relatados. CONCLUSÕES: Os tipos de exercícios terapêuticos para lombalgia crônica ou aguda que são mais eficazes, ainda são bastante controversos, contudo exercícios terapêuticos são provavelmente o tratamento conservativo mais usado no mundo todo.

Evaluación del paciente con dolor lumbar / Evaluation of patients with low back pain

El dolor lumbar es una afección muy frecuente y con alta repercusión socio-económica en la sociedad occidental, a pesar que la mayoría de las veces su curso es autolimitado. La degeneración discal es un proceso de envejecimiento normal pero su rol en la etiopatogenia del dolor lumbar es significativo. Esta revisión muestra un enfoque clínico práctico para clasificar a estos enfermos de las primeras consultas, de manera de identificar rápidamente etiologías que requieren un manejo especializado y precoz. Enseguida, se describen recomendaciones acerca del manejo inicial en el dolor lumbar inespecífico, basadas en guías clínicas, propuestas por grupos de expertos en base a evidencias de la literatura publicadas recientemente.

Mostly, back pain is a self limiting condition but, his high incidence involves great social and economics costs. Age-related changes of disc degeneration doesn´t explain all the cases of lumbar problems. This review looks at a practical approach to this patients in the first examination for recognize the clinical entities that require early and specialized treatment. Then, it describes guidelines for the initial management in specific back pain based in recent publications.

Validation in the Cross-Cultural Adaptation of the Korean Version of the Oswestry Disability Index

Disability questionnaires are used for clinical assessment, outcome measurement, and research methodology. Any disability measurement must be adapted culturally for comparability of data, when the patients, who are measured, use different languages. This study aimed to conduct cross-cultural adaptation in translating the original (English) version of the Oswestry Disability Index (ODI) into Korean, and then to assess the reliability of the Korean versions of the Oswestry Disability Index (KODI). We used methodology to obtain semantic, idiomatic, experimental, and conceptual equivalences for the process of cross-cultural adaptation. The KODI were tested in 116 patients with chronic low back pain. The internal consistency and reliability for the KODI reached 0.9168 (Cronbach's alpha). The test-retest reliability was assessed with 32 patients (who were not included in the assessment of Cronbach's alpha) over a time interval of 4 days. Test-retest correlation reliability was 0.9332. The entire process and the results of this study were reported to the developer (Dr. Fairbank JC), who appraised the KODI. There is little evidence of differential item functioning in KODI. The results suggest that the KODI is internally consistent and reliable. Therefore, the KODI can be recommended as a low back pain assessment tool in Korea.
