A Rare Cause of Chronic Low Back Pain

Objectives: Autosomal dominant osteopetrosis (ADO) is a rare genetic disease characterized by increased bone mass and density due to defective bone resorption. The aim of this case study is to present the clinical and radiographic features of a 22-year-old male patient with ADO and to serve as a reminder that this rare disease should be considered in the differential diagnosis of chronic low back pain. Materials and methods: A 22-year-old patient with ADO is presented in this case report. Results: Clinical and radiographic features of the patient were consistent with ADO. Conclusions: ADO should be taken into consideration in differential diagnosis of low back pain.

Biomechanics of the trunk and lower limbs during gait in individuals with and without chronic low back pain

Combining information on kinetics and kinematics of the trunk during gait is important for both clinical and research purposes, since it can help in better understanding the mechanisms behind changes in movement patterns in chronic low back pain patients. Although three-dimensional gait analysis has been used to evaluate chronic low back pain and healthy individuals, the reliability and measurement error of this procedure have not been fully established. The main purpose of this thesis is to gain a better understanding about the differences in the biomechanics of the trunk and lower limbs during gait, in patients and healthy individuals. To achieve these aims, three studies were developed. The first two, adopted a prospective design and focused on the reliability and measurement error of gait analysis. In these test-retest studies, chronic low back pain and healthy individuals were submitted to a gait assessment protocol, with two distinct evaluation moments, separated by one week. Gait data was collected using a 13-camera opto-electronic system and three force platforms. Data analysis included the computation of time-distance parameters, as well as the peak values for lower limb and trunk joint angles/moments. The third study followed a cross sectional design, where gait in chronic low back pain individuals was compared with matched controls. Step-to-step variability of the thoracic, lumbar and hips was calculated, and step-to-step deviations of these segments from their average pattern (residual rotations) were correlated to each other. The reliability studies in this thesis show that three-dimensional gait analysis is a reliable and consistent procedure for both chronic low back pain and healthy individuals. The results suggest varied reliability indices for multi-segment trunk joint angles, joint moments and time-distance parameters during gait, together with an acceptable level of error (particularly regarding sagittal plane). Our findings also show altered stride-to-stride variability of lumbar and thoracic segments and lower trunk joint moments in patients. These kinematic and kinetic results lend support to the notion that chronic low back pain individuals exhibit a protective movement strategy.

Prevalencia de Dolor Lumbar y su Relación con Factores de Riesgo Biomecánico en Persona de Enfermería

Objetivo Determinar la prevalencia de dolor lumbar y su relación con los factores de riesgo biomecánico en el personal de enfermería de una entidad de salud de cuarto nivel en la ciudad de Bogotá, entre el año 2014 y 2015. Esta investigación se realizó teniendo en cuenta que el dolor lumbar tiene un alto impacto en la calidad de vida del personal de enfermería. Materiales y métodos: Es un estudio de corte transversal con exploración analítica. La población objeto de estudio está conformada por 866 trabajadores de enfermería de la cual se tomó una muestra de 265 individuos a los cuales se les aplicó un cuestionario online que indagó acerca de las características individuales, laborales de riesgo biomecánico. En la elaboración del instrumento se seleccionaron ítems de Ergopar y Nórdico. La muestra fue aleatoria, estratificada con distribución proporcional por servicio de atención y jornada laboral. Resultados La prevalencia de dolor lumbar en la población estudiada fue del 61.1% (n=162) con un intervalo de confianza del 95% (55.1-67.2). Los factores de riesgo biomecánico asociados al problema de estudio fueron: posturas que implican girar y/o inclinar la espalda o el tronco (p 0.05), y tiempo de movilización de pacientes (p 0.01). Los factores a nivel laboral que se relacionan con el dolor lumbar son: el tipo de contrato (p 0.002), las exigencias físicas del trabajo (p 0.001) y la imposibilidad para realizar el trabajo por causa del dolor lumbar (p 0.000). La prevalencia por servicios y la jornada laboral no presentaron asociación significativa. Conclusiones La prevalencia de dolor lumbar en personal de enfermería es alta y coincide con los estudios realizados a nivel nacional e internacional. La exposición a los factores de riesgo biomecánico que se relacionan con la presencia de dolor lumbar en el personal de enfermería, afectan su calidad de vida. Además, no existen diferencias significativas de acuerdo con las funciones de los cargos desempeñados.

Relationship between Health-Related Quality of Life, Pain, and Functional Disability in Neuropathic Pain Patients with Failed Back Surgery Syndrome.

ABSTRACT Objectives: Patients with failed back surgery syndrome (FBSS) and chronic neuropathic pain experience levels of health-related quality of life (HRQoL) that are considerably lower than those reported in other areas of chronic pain. The aim of this article was to quantify the extent to which reductions in (leg and back) pain and disability over time translate into improvements in generic HRQoL as measured by the EuroQoL-5D and SF-36 instruments. Methods: Using data from the multinational Prospective, Randomized, Controlled, Multicenter Study of Patients with Failed Back Surgery Syndrome trial, we explore the relationship between generic HRQoL-assessed using two instruments often used in clinical trials (i.e., the SF-36 and EuroQol-5D)-and disease-specific outcome measures (i.e., Oswestry disability index [ODI], leg and back pain visual analog scale [VAS]) in neuropathic patients with FBSS. Results: In our sample of 100 FBSS patients, generic HRQoL was moderately associated with ODI (correlation coefficient: -0.462 to -0.638) and mildly associated with leg pain VAS (correlation coefficient: -0.165 to -0.436). The multilevel regression analysis results indicate that functional ability (as measured by the ODI) is significantly associated with HRQoL, regardless of the generic HRQoL instrument used. On the other hand, changes over time in leg pain were significantly associated with changes in the EuroQoL-5D and physical component summary scores, but not with the mental component summary score. Conclusions: Reduction in leg pain and functional disability is statistically significantly associated with improvements in generic HRQoL. This is the first study to investigate the longitudinal relationship between generic and disease-specific HRQoL of neuropathic pain patients with FBSS, using multinational data.

The contribution of self-efficacy and depression to disability and work status in chronic pain patients: A comparison between Australian and Brazilian samples

There is evidence that cognitions (beliefs) and mood contribute to physical disability and work status in people with chronic pain. However, most of the current evidence comes from North America and Europe. This study examined the contribution of demographic, pain and psychosocial factors to disability and work status in chronic pain patients in two matched samples from quite different countries (Australia and Brazil). Data were collected from 311 chronic pain patients in each country. The results suggest that although demographic and pain variables (especially pain levels) contribute disability, self-efficacy beliefs made a significant contribution to disability in both samples. Age and educational level also contributed to unemployment in both samples. But there were some differences, with self-efficacy and physical disability contributing to work status only in the Brazilian sample. In contrast, depression was the only psychological risk factor for unemployment in the Australian sample. Catastrophising and pain acceptance did not contribute to disability or unemployment in either sample. These findings confirm key aspects of biopsychosocial models of pain in two culturally and linguistically different chronic pain samples from different countries. They suggest that different chronic pain populations may share more similarities than differences. (C) 2008 European Federation of Chapters of the International Association for the Study of Pain.
