Investigating Factors Associated with Fear of Falling in Community-Dwelling Older Adults through Structural Equation Modeling Analysis: A Cross-Sectional Study.

The scientific literature mentions the existence of factors associated with fear of falling in older adults. However, the direct and indirect paths of its predictors have not yet been fully explored. This study aimed to analyze the socioeconomic, clinical, and health factors directly and indirectly associated with fear of falling in community-dwelling older adults. This is a cross-sectional study conducted in older adults (n = 410 - 70.11 ± 7.22 years). Clinical and health-condition data were collected, as were data on fear of falling using the Falls Efficacy Scale International-Brazil (FES-I Brazil). It was found that being female and having a higher number of self-reported morbidities, worse physical performance, and a higher number of depressive symptoms were directly associated with greater fear of falling. Regarding indirect associations, physical inactivity, mediated by a greater number of morbidities, worse physical performance, and a greater number of depressive symptoms, was associated with greater fear of falling. In addition, worse self-rated health, mediated by a greater number of depressive symptoms, as well as older age, mediated by worse physical performance, were associated with the outcome. This study provides information on the predictors directly and indirectly associated with fear of falling, expanding current understanding of this relationship.

Brief Lower Body Functional Performance Questionnaire (Brief-LBFPQ) for independent older adults / Breve Questionário de Desempenho Funcional dos Membros Inferiores (Brief-LBFPQ) para idosos independentes

Abstract Introduction The literature still lacks evidence about patient-reported outcome measures to fast screen the reduced physical performance of the lower body in older adults to be applied in any clinical setting as primary health care or without specific instruments in prevention campaigns, or even easy to be applied by phone. Objective: To develop a brief questionnaire to screen the lower body functional performance in community-dwelling older adults and to validate this new questionnaire with objective clinical tests. Methods A convenience sampling of 221 community-dwelling older adults was included in this cross-sectional study. The validity between Brief-LBFPQ and objective tests such as gait speed, Timed-Up and Go test (TUG), 5-Time Stand-to-Sit test (5TSST), and step test were assessed by multinominal logistic regression. Internal consistency was determined using Cronbach's alpha and Test-retest reliability was determined using intraclass correlation coefficient (ICC) for numeral scale and Cohen's Kappa for ordinal scale. Results Brief-LBFPQ was significantly associated with objective tests. All eight items from Brief-LBFPQ presented an absolute agreement with ICCs values above 0.7. Kappa values of Brief-LBFPQ items ranged from 0.6 to 0.83, showing substantial agreement and perfect agreement. Conclusion Brief-LBFPQ could be very useful in general clinic settings as it provides earlier screening of functional impairment in independent older adults, and consequently may allow an earlier intervention approach.

Resumo Introdução A literatura ainda carece de evidências acerca de instrumentos de autorrelato para o rastreio rápido do prejuízo no desempenho físico dos membros inferiores em idosos, que possam ser aplicados em qualquer ambiente clínico, como na Atenção Básica à Saúde, e que não requeiram nenhum ins-trumento específico para campanhas de prevenção, ou mesmo de fácil aplicação por contato telefônico. Objetivo Desenvolver um breve questionário para triagem do desempenho funcional dos membros inferiores em idosos da comunidade e validar este novo questionário com testes clínicos objetivos. Métodos Uma amostra de conveniência de 221 idosos da comunidade foi incluída neste estudo transversal. A validade entre o Brief-LBFPQ e os testes objetivos como velocidade da marcha, Timed-Up and Go (TUG), teste de levantar e sentar 5 vezes (TLS5x) e teste do degrau foi avaliada pela regressão logística multinominal. A consistência interna foi determinada pelo alfa de Cronbach e a confiabilidade teste-reteste foi determinada pelo coeficiente de correlação intraclasse (CCI) para a escala numérica e o Kappa de Cohen para a escala ordinal. Resultados O Brief-LBFPQ foi significativamente associado aos testes objetivos. Todos os oito itens do Brief-LBFPQ apresentaram concordância absoluta com valores de CCI acima de 0,7. Os valores de Kappa dos itens do Brief-LBFPQ variaram de 0,6 a 0,83, mostrando concordância substancial e concordância perfeita. Conclusão O Brief-LBFPQ pode ser muito útil em diferentes ambientes clínicos, pois permite uma triagem precoce do comprometimento funcional em idosos independentes e, consequentemente, pode permitir uma abordagem de intervenção mais precoce.

Blood flow restriction with different load levels in patients with knee osteoarthritis: protocol of a randomized controlled trial.

BACKGROUND: The effectiveness of blood flow restriction training (BFR) in elderly with knee osteoarthritis (OA) is comparable to performing high-intensity protocols (70 to 80% of 1 RM [repetition maximum]) that are known to be effective for improving the muscle strength of knee extensors, with the advantage of generating less particular rating of perceived exertion and pain immediately after training. However, despite being a promising alternative, little is known about the best way to apply the BFR, such as level of pressure and combination or not with other therapeutic modalities. The purpose of this study is to evaluate whether different levels of blood flow restriction with low load (BFR + LL) and no load (BFR + rest) are non-inferior to high-intensity resistance exercise (HIRE+BFRplacebo) for pain reduction in patients with knee OA. METHODS/DESIGN: This clinical trial is a non-inferiority, five-arm, randomized, active-controlled, single trial which will be carried out in 165 patients of both sexes with knee OA, aged 50 years and older. Participants will be randomly allocated into 5 exercise groups (40% of BFR + LL; 80% of BFR + LL; 40% of BFR + rest; 80% BFR + rest, and HIRE+BFR placebo). A mixed linear model will be used to examine the effect of group-by-time interaction on pain intensity on the WOMAC subscale (primary outcome) and on disease severity, physical functional data, balance data, quality of life, global perceived effect scale, and muscle strength (secondary outcomes). Participants will be analyzed for intention-to-treat, and the statistical assessor blinded to the groups. The collection of outcomes 72 h after completion of the 16 weeks of interventions will be the primary measurement point. Follow-up secondary timepoints will be collected at 20, 28, 40, 52, and 64 weeks after the end of interventions, except for pain during the training, which will be measured immediately at the end of each session. Only the comparison of the primary outcome between the HIRE group with each BFR group will be analyzed in the non-inferiority framework, the other comparisons between the BFR groups for the primary outcome, and all secondary outcomes will be interpreted in the superiority framework. DISCUSSION: The results of this clinical trial can point out more clearly to ways to optimize the BFR training with the minimum of pain immediately after training, which will allow the offer of an effective and more adherent strengthening training to patients with knee OA.

Isokinetic ankle muscle strength is reduced in recreational runners with medial tibial stress syndrome and is not associated with pain

Abstract Aim: The purpose of this study was to investigate the strength and ratios of the plantar flexors and ankle dorsiflexors in recreational runners with medial tibial stress syndrome and to assess the association between muscle strength and the level of pain in this population. Methods: Two groups (control and medial tibial stress syndrome) of eighteen runners each participated in this cross-sectional study. Isokinetic dynamometry was used to evaluate muscle strength, and for the analysis, the normalized isokinetic peak torque controlled by gender was used. Results: The medial tibial stress syndrome group showed lower normalized isokinetic peak torque in the dorsiflexors in the concentric (p = 0.008) eccentric (p = 0.011) contraction, as well as a lower plantar flexor, normalized isokinetic peak torque in the concentric (p = 0.001) and eccentric (p = 0.02) when compared to the control group. However, there was no difference in the normalized isokinetic peak torque ratio representative of the stance (p = 0.62) and swing phase (p = 0.16), and the level of pain was not correlated with the strength concentric (p = 0.32) and eccentric (p = 0.621) of plantar flexors, nor to the concentric (p = 0.21) and eccentric of dorsiflexors (p = 0.54). Conclusion: Recreational runners with MTSS showed decreased muscle strength in the sagittal plane of the ankle, no correlation with the level of pain, and no changing the ratio between plantar flexors and dorsiflexors.

Clinical and socioeconomic characteristics of older adults with COVID-19: A protocol for a rapid systematic review.

The aim of this rapid systematic review is to analyze the prevalence of clinical, socioeconomic, and demographic characteristics, laboratory and imaging findings, diagnostic tests, and treatment information of older adults with COVID-19. To conduct this systematic review, the Cochrane Handbook recommendations will be followed. Patients aged 60 years or older with a confirmed diagnosis of SARS-CoV-2 infection will be included. A comprehensive literature search will be performed in the following databases: MEDLINE via PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Latin American and Caribbean Health Sciences Literature (LILACS), Spanish Bibliographic Index on Health Sciences (IBECS) and Epistemonikos COVID-19 L·OVE platform.

Risk factors for future falls among community-dwelling older adults without a fall in the previous year: A prospective one-year longitudinal study.

INTRODUCTION: One of the main risk factor for falls is a history of falls itself. Henceforth, preventing a fall is an important strategy for the prevention of new ones. The objective of the present study was to determine whether personal self-perception questions and functional tests might represent risk factors for a fall during the year following a year without any falls among independent community-dwelling older adults, considering a period of 12 prospective months. METHODS: A total of 101 community-dwelling older adults without a fall in the previous year underwent an initial evaluation (sample characterization, self-perception questionnaire and functional tests) and monthly monitoring of prospective fall episodes by telephone contact. We determined the association between the occurrence of prospective falls (dependent variable) and personal questions and functional tests (independent variables) with multiple binary logistic regression adjusted for confounding variables. RESULTS: Only age (p = 0.005) and self-perception of general health (p = 0.019) showed association with the occurrence of prospective falls. CONCLUSION: Our results showed that the only factors bearing an association with the occurrence of prospective falls were age and general health self-perception, which demonstrates the importance of administrating self-perception measures in clinical practice or in epidemiological studies for the prevention of a fall during the year following a year without any falls in older adults.

Recomendações para prescrição de dispositivos auxiliares da marcha em idosos / Recommendations for prescribing walking aids in older adults

O uso de um dispositivo auxiliar da marcha (DAM), como bengala ou andador, pode auxiliar os idosos na realização de suas atividades diárias, mantendo-os funcionalmente independentes e relativamente ativos. Porém, a utilização inadequada, o mau estado e as dimensões incorretas do dispositivo, assim como erros na prescrição do tipo de dispositivo podem aumentar o risco de quedas nos idosos usuários de DAM. Diante da falta de recomendações quanto à sua prescrição, o objetivo desse artigo é discorrer sobre os pré-requisitos para a prescrição de cada dispositivo (bengala e andador), de acordo com a nossa experiência adquirida na Área de Fisioterapia em Gerontologia, no Centro de Reabilitação (CER) do Hospital das Clínicas de Ribeirão Preto, considerando as evidências científicas disponíveis até o momento. Assim, com a difusão das informações contidas nesse artigo para os profissionais da saúde que prestam assistência a idosos, espera-se aprimorar a prática de prescrição do DAM e de educação do idoso, de seus familiares e cuidadores, a fim de que sejam alcançados os benefícios do uso de um DAM e prevenidos os possíveis eventos adversos, como as quedas.

The use of a walking aid device (WAD), such as a cane or walker, can assist older adults in performing their daily activities, keeping them functionally independent and relatively active. However, improper use, poor condition and incorrect dimensions of the device, as well as errors in prescribing the type of device may increase the risk of falls in older people who use a WAD. Given the lack of recommendations on its prescription, the purpose of this article is to discuss the requirements for the prescription of each device (cane and walker), according to our experience obtained in the area of ​​Gerontology Physiotherapy in the Rehabilitation Center (CER) of the Hospital das Clínicas de Ribeirão Preto, considering the scientific evidence available at the moment. Thus, by disseminating the information contained in this article to health professionals who provide care to older people, it is expected to improve the practice of prescribing WAD and educating the older adults, their families and caregivers, in order to achieve the benefits of use a WAD and prevent possible adverse events such as falls.
