Factors associated with attitudes and beliefs of elders with acute low back pain: data from the study Back Complaints in the Elders (BACE)

ABSTRACT Background The attitudes and beliefs that older people have about acute low back pain (LBP) may influence the coping mechanisms and the adoption of treatment strategies in this population. Objective The aim of this study was to identify the factors associated with the attitudes and beliefs of elderly patients with acute low back pain using the Back Beliefs Questionnaire. Method This is a cross-sectional study with a subsample of the study “Back Complaints in the Elders” (BACE), composed of 532 older Brazilians of both genders with acute LBP. We investigated sociodemographic and clinical aspects, self-perceived health, psychosocial and emotional state, falls, and functional capacity. Multiple regression models were constructed to measure possible associations. Results The percentage of female participants was 85.7% and the mean age was 69.04 (SD=6.2). Disability, symptoms of depression, and expectation of return to activities were independently associated with attitudes and beliefs concerning LBP. Conclusion Screening of psychosocial factors is essential to the prevention of persistent and recurrent LBP. Early signs of these factors can help identify symptoms and behaviors for effective interventions.

Prospective monitoring and self-report of previous falls among older women at high risk of falls and fractures: a study of comparison and agreement

Background: The identification of the occurrence of falls is an important step for screening and for rehabilitation processes for the elderly. The methods of monitoring these events are susceptible to recording biases, and the choice of the most accurate method remains challenging. Objectives: (i) To investigate the agreement between retrospective self-reporting and prospective monitoring of methods of recording falls, and (ii) to compare the retrospective self-reporting of falls and the prospective monitoring of falls and recurrent falls over a 12-month period among older women at high risk of falls and fractures. Method: A total of 118 community-dwelling older women with low bone density were recruited. The incidence of falls was monitored prospectively in 116 older women (2 losses) via monthly phone calls over the course of a year. At the end of this monitoring period, the older women were asked about their recall of falls in the same 12-month period. The agreement between the two methods was analyzed, and the sensitivity and specificity of self-reported previous falls in relation to the prospective monitoring were calculated. Results: There was moderate agreement between the prospective monitoring and the retrospective self-reporting of falls in classifying fallers (Kappa=0.595) and recurrent fallers (Kappa=0.589). The limits of agreement were 0.35±1.66 falls. The self-reporting of prior falls had a 67.2% sensitivity and a 94.2% specificity in classifying fallers among older women and a 50% sensitivity and a 98.9% specificity in classifying recurrent fallers. Conclusion: Self-reporting of falls over a 12-month period underestimated 32.8% of falls and 50% of recurrent falls. The findings recommend caution if one is considering replacing monthly monitoring with annual retrospective questioning. .

Intra and inter-rater reliability study of pelvic floor muscle dynamometric measurements

OBJECTIVE: The aim of this study was to evaluate the intra and inter-rater reliability of pelvic floor muscle (PFM) dynamometric measurements for maximum and average strengths, as well as endurance. METHOD: A convenience sample of 18 nulliparous women, without any urogynecological complaints, aged between 19 and 31 (mean age of 25.4±3.9) participated in this study. They were evaluated using a pelvic floor dynamometer based on load cell technology. The dynamometric evaluations were repeated in three successive sessions: two on the same day with a rest period of 30 minutes between them, and the third on the following day. All participants were evaluated twice in each session; first by examiner 1 followed by examiner 2. The vaginal dynamometry data were analyzed using three parameters: maximum strength, average strength, and endurance. The Intraclass Correlation Coefficient (ICC) was applied to estimate the PFM dynamometric measurement reliability, considering a good level as being above 0.75. RESULTS: The intra and inter-raters' analyses showed good reliability for maximum strength (ICCintra-rater1=0.96, ICCintra-rater2=0.95, and ICCinter-rater=0.96), average strength (ICCintra-rater1=0.96, ICCintra-rater2=0.94, and ICCinter-rater=0.97), and endurance (ICCintra-rater1=0.88, ICCintra-rater2=0.86, and ICCinter-rater=0.92) dynamometric measurements. CONCLUSIONS: The PFM dynamometric measurements showed good intra- and inter-rater reliability for maximum strength, average strength and endurance, which demonstrates that this is a reliable device that can be used in clinical practice. .

Influence of dual task and frailty on gait parameters of older community-dwelling individuals

Background: Gait parameters such as gait speed (GS) are important indicators of functional capacity. Frailty Syndrome is closely related to GS and is also capable of predicting adverse outcomes. The cognitive demand of gait control is usually explored with dual-task (DT) methodology. Objective: To investigate the effect of DT and frailty on the spatio-temporal parameters of gait in older people and identify which variables relate to GS. Method: The presence of frailty was verified by Fried's Frailty Criteria. Cognitive function was evaluated with the Mini-Mental State Exam (MMSE) and gait parameters were analyzed through the GAITRite(r) system in the single-task and DT conditions. The Kolmogorov-Smirnov, ANOVA, and Pearson's Correlation tests were administered. Results: The participants were assigned to the groups frail (FG), pre-frail (PFG), and non-frail (NFG). During the DT, the three groups showed a decrease in GS, cadence, and stride length and an increase in stride time (p<0.001). The reduction in the GS of the FG during the DT showed a positive correlation with the MMSE scores (r=730; p=0.001) and with grip strength (r=681; p=0.001). Conclusions: Gait parameters are more affected by the DT, especially in the frail older subjects. The reduction in GS in the FG is associated with lower grip strength and lower scores in the MMSE. The GS was able to discriminate the older adults in the three levels of frailty, being an important measure of the functional capacity in this population. .

Influence of sarcopenia and functionality indicators on the frailty profile of community-dwelling elderly subjects: a cross-sectional study

BACKGROUND: Frailty and sarcopenia are frequent conditions in the elderly and are related to inactivity and functionality. However, little is known about the influence of the sarcopenia indicators on the frailty profile or their functional implications. OBJECTIVE: To evaluate whether the indirect indicators of sarcopenia and functionality influence the frailty profile in elderly subjects. METHOD : This was a cross-sectional study with 53 elderly subjects recruited by an active search in a secondary health care service. The indirect indicators of sarcopenia were body mass index (BMI), gait speed, Mini-Nutritional Assessment (MNA), Human Activity Profile (HAP), and handgrip strength. Frailty was characterized according to Fried's Frailty Phenotype. Functional capacity was assessed according to the Short Physical Performance Battery (SPPB). Physical activity level was assessed by HAP. Data were analyzed by analysis of variance (ANOVA) and multiple regression. RESULTS: Overall, 75.5% of the subjects were women, with a mean age of 76.72 (±5.89) years; 15.1% were frail and 54.7% pre-frail; and the level of physical activity was the most prevalent indicator of sarcopenia. Significant differences (p<0.05) were observed in both the physical activity level and gait speed between the non-frail and pre-frail groups and between the non-frail and frail groups. In addition, some sarcopenia indicators were associated with functional capacity and geriatric depression score. CONCLUSION: The level of physical activity and gait speed appeared to be the most relevant factors in the development of frailty in the study sample, which may have functional implications. .

Functional and cognitive changes in community-dwelling elderly: Longitudinal study / Mudancas funcionais e cognitivas em idosos da comunidade: estudo longitudinal

BACKGROUND: The relationship between aging and increased life expectancy in the overall population likely contributes to a higher frequency rate and incidence of illnesses and functional disabilities. Physical dependence and cognitive impairment might hinder the performance of activities and result in an overload of care duties for the patient's family and the healthcare system. OBJECTIVE: The aim of this study was to compare the functional and cognitive changes exhibited by the elderly over a 6-month period. METHOD: This longitudinal and observational study was conducted in a sample of 167 elderly people, who were selected from the database of the Network of Studies on Frailty in Brazilian Elderly, Universidade Federal de Minas Gerais - UFMG. The participants submitted to the Mini Mental State Examination (MMSE), Katz Index, Lawton and Brody's scale and responded to items on Advanced Activities of Daily Living (AADLs). We analyzed the data using multivariate regression models. RESULTS: The participants' functional capacity exhibited reduced performance of specific instrumental activities of daily living (IADLs), p=0.002, and basic activities of daily living (BADLs), p=0.038. Living alone (odds ratio (OR), 2.53; 95% confidence interval (CI), 1.09-5.87) and work status (OR, 2.52; 95% CI, 1.18-5.41) were associated with changes in the IADLs. The scores in the AADL scale (p=0.163) and MMSE (p=0.059) did not exhibit any significant difference during the study period. The participants with better cognitive function were more independent in their performance of AADLs and IADLs. CONCLUSION: The results depict specific patterns of loss and stability of functional capacity in community-dwelling elderly. .

CONTEXTUALIZAÇÃO: O processo de envelhecimento associado à ampliação da expectativa de vida da população pode acarretar um aumento da prevalência e incidência de doenças e de prejuízos à funcionalidade. A dependência física e o comprometimento cognitivo podem impedir o desempenho de atividades, gerando uma sobrecarga de cuidados para a família e para o sistema de saúde. OBJETIVO: Comparar as mudanças funcionais e cognitivas em idosos ocorridas num período de seis meses. MÉTODO: Trata-se de um estudo observacional longitudinal, com uma amostra de 167 idosos, selecionados a partir do banco de dados da Rede de Estudos da Fragilidade em Idosos Brasileiros do polo da Universidade Federal de Minas Gerais (UFMG). Os participantes responderam ao Miniexame do Estado Mental (MEEM), ao Índice de Katz, a Escala de Lawton e Brody e a questões relativas à Atividade Avançada de Vida Diária (AAVD). Os dados foram analisados com modelos de regressão multivariada. RESULTADOS: Observou-se diminuição da capacidade funcional nas Atividades Instrumentais de Vida Diária (AIVD), p=0,002, e, nas Atividades Básicas de Vida Diária (ABVD), p=0,038, em algumas atividades específicas. Morar sozinho (OR=2,53; IC=1,09:5,87) e condição de trabalho (OR=2,52; IC=1,18:5,41) associaram-se a mudança nas AIVD. Não houve diferença significativa no período de tempo do acompanhamento, na pontuação da AAVD, p=0,163, e do MEEM, p=0,059. Observou-se que os indivíduos com melhor cognição eram mais independentes nas AAVD e nas AIVD. CONCLUSÃO: Esses resultados revelam perfis específicos de perda e de estabilidade na funcionalidade de idosos comunitários. .
