The impact of low back pain and disability on frailty levels in older women: longitudinal data from the BACE-Brazil cohort.

METHODS: This is a longitudinal observational study with a convenience subsample from the international Back Complaints in the Elders (BACE)-Brazil. Frailty was assessed by researchers at baseline, 6 and 12 months according to the Frailty Phenotype. Pain was assessed using a Numerical Pain Scale (NPS). Disability was assessed using the Roland Morris Disability Questionnaire. RESULTS: A total of 155 older women (70.4 ± 5.4 years) participated. Follow-up for 6 and 12 months in this study was associated with a change of older women to worse frailty levels (OR = 2.83, 95% CI 1.98-4.67; p < 0.01). A significant association was observed between greater pain intensity and the transition of the older women through the frailty levels (ß = - 0.73; p < 0.01) when inserting the pain variable at baseline of the statistical model. Older women who reported greater pain intensity worsened their frailty level. The same happened when the disability variable was inserted in the model (ß = - 0.74; p < 0.01). The criteria proposed by Fried et al. were able to identify frailty throughout the follow-up and no prevalence of any item. CONCLUSIONS: In older women, relevant factors such as pain and disability are closely linked to the frailty phenomenon. Thus, the frailty syndrome must be assessed, monitored and treated in relation to the individualities of older adults, as those with back pain and greater disabilities are more susceptible to frailty.

Use of healthcare services and therapeutic measures associated with new episodes of acute low back pain-related disability among elderly people: a cross-sectional study on the Back Complaints in the Elders - Brazil cohort.

BACKGROUND: Patients with low back pain frequently undergo a variety of diagnostic and therapeutic interventions, but some of these have uncertain effectiveness. This highlights the importance of the association of healthcare services and therapeutic measures relating to disability. OBJECTIVE: To analyze the use of healthcare services and therapeutic measures among Brazilian older adults with disability-related low back pain. DESIGN AND SETTING: Observational cross-sectional study on baseline assessment data from the Back Complaints in the Elders - Brazil (BACE-B) cohort. METHODS: The main analyses were based on a consecutive sample of 602 older adult participants in BACE-B (60 years of age and over). The main outcome measurement for disability-related low back pain was defined as a score of 14 points or more in the Roland Morris Questionnaire. RESULTS: Visits to doctors in the previous six weeks (odds ratio, OR = 1.82; 95% confidence interval, CI 1.22-2.71) and use of analgesics in the previous three months (OR = 1.57; 95% CI 1.07-2.31) showed statistically significant associations with disability-related low back pain. The probability of disability-related low back pain had an additive effect to the combination of use of healthcare services and therapeutic measures (OR = 2.57; 95% CI 1.52-4.36). The analyses showed that this association was significant among women, but not among men. CONCLUSIONS: Occurrence of the combined of consultations and medication use was correlated with higher chance of severe disability among these elderly people with nonspecific low back pain. This suggested that overuse and "crowding-in" effects were present in medical services for elderly people.

The effect of kinesiophobia in older people with acute low back pain: longitudinal data from Back Complaints in the Elders (BACE).

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.

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

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.

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.

ABSTRACT Introduction: Physical activity is an important parameter to be quantified in the elderly. Reliable measurement instruments are needed to evaluate, and design effective therapeutic intervention targets and to monitor patient outcomes. Objective: To adapt cross-culturally and determine the test-retest and inter-rater reliability of the Active Australia Questionnaire in community elders. Methods: A cross-cultural adaptation was performed according to the criteria proposed by Guillemin and Beaton, namely, translation, back-translation, synthesis of translations, submission to the expert committee and implementation of the pre-final version to test the questionnaire. For test-retest reliability, a four-hour interval was given for collection, and a six-hour interval for inter-rater analysis, following the retest. Physical activity information was considered in the last seven days. The characterization of the sample was done by descriptive analysis. For the analysis of reliability we used the intraclass correlation coefficient (ICC). The study included 22 elderly (72.5 ± 5.3 years) and 7.6 ± 3.9 years of education. Results: Test-retest reliability was ICC = 0.97 and the inter-rater reliability was ICC= 0.82. Conclusion: The instrument was semantically and linguistically adequate and reliable to evaluate the level of physical activity in the elderly in the community.
