ABSTRACT

Background: We investigated the effects of a 12-week home-based exercise program delivered with virtual or minimal supervision on the physical and cognitive function of community-dwelling older adults in the context of the COVID-19 pandemic in Brazil. Methods: The study was registered on the Brazilian Registry of Clinical Trials platform (code: RBR-8qby2wt). Thirty-eight older adults (81% female and 68±7 years old), non-disabled, and without cognitive impairment or dementia, were randomly assigned to a 12-week home-based exercise program: 1) virtual supervision (classes remotely delivered through video conference by trained staff), or 2) minimal supervision (once-weekly contact to touch base through standardized text messages). The participants initially performed two sets of 10 repetitions three times a week, with a 60-second interval. The volume and complexity of the exercises were progressively increased. (e.g., the number of sets increased to 3 and later to 4). At baseline and follow-up, we collected remote measurements of physical function (muscle strength and power, functional muscular fitness) and cognition (processing speed, inhibitory control, verbal fluency). Results: Participants in the minimal supervision home-based exercise group significantly improved the Stroop test (-1.6 sec, 95% CI = -3.20; -0.09). No significant between-group differences were observed for physical and cognitive outcomes. Conclusion: A home-based exercise program delivered with virtual or minimal supervision can produce similar effects, and may help to maintain physical and cognitive capabilities among healthy, high-functioning older adults who experienced mobility restrictions due to the COVID-19 pandemic in Brazil.

ABSTRACT

This study sought to review randomized clinical trials of home-based physical exercises and their effects on cognition in older adults. An integrative review was carried out after searching the PubMed, Google Scholar, MEDLINE, LILACS, SciELO, and PEDro databases. The risk of bias of the included randomized controlled trials was assessed using the PEDro Scale. Fourteen studies were included, with an average PEDro score of 6.1±1.7 (range, 3 to 9) points. Overall, the studies found that interventions consisting of home-based physical exercise programs, whether strength training alone or combined with aerobic and balance exercises, performed three times a week in 60-minute sessions for a minimum duration of 8 weeks, contribute to cognitive performance in older adults, with particular impact on executive function. We conclude that home-based physical exercises constitute a strategy to minimize the negative implications associated with cognitive impairment in older adults


Este estudo buscou revisar ensaios clínicos randomizados com exercícios físicos domiciliares e seus efeitos na cognição de idosos. Foi feita uma revisão integrativa com seleção nas bases de dados PubMed, Google Scholar, MEDLINE, LILACS, SciELO e PEDro. A avaliação do risco de viés dos ensaios clínicos randomizados incluídos foi feita usando a Escala PEDro. Catorze estudos foram incluídos, cuja pontuação dos artigos na escala PEDro foi em média de 6,1±1,7 pontos, com a pontuação total variando de 3 a 9. De forma geral, os estudos apontaram que a intervenção com programas de exercícios domiciliares de treino de força isolado ou combinado com exercícios aeróbio e de equilíbrio, realizado três vezes na semana com 60 minutos por sessão e duração mínima de oito semanas, contribui para o desempenho cognitivo de idosos, especialmente sobre a função executiva. Concluiu-se que exercícios domiciliares se apresentam como uma estratégia para minimizar as consequências negativas associadas ao déficit cognitivo em idosos

ABSTRACT

OBJECTIVE: We aimed to determine the feasibility and reliability of videoconference assessment of functional and cognitive status among older adults in the context of the COVID-19 pandemic. METHODS: Thirty community-dwelling older adults (86.70% women) with a mean age of 69.77 (SD = 6.60) years who were physically independent and had no signs of cognitive impairment were included in the sample. An independent and experienced researcher assessed functional (chair rise test, chair stand test, sitting and rising test) and cognitive (Montreal Cognitive Assessment, parts A and B of the Trail Making Test, the Stroop test, the verbal fluency test) performance in real-time on the Google Meet platform on 2 non-consecutive days. The reliability of the measures was analyzed using the intraclass correlation coefficient (ICC), a paired t-test, or Wilcoxon and Bland-Altman analysis. The feasibility of the assessment was investigated using a standardized 14-item questionnaire. RESULTS: All functional performance measures showed excellent intra-rater reliability, with ICCs from 0.90 (95%CI 0.78 ­ 0.95) for the sitting and rising test to 0.98 (95%CI 0.96 ­ 0.99) for the chair rise test. Our analysis also showed mixed levels of reliability across measures, including good ICC (ranging from 0.79 ­ 0.91) for the Montreal Cognitive Assessment, part B of the Trail Making Test, and the congruent and neutral trials in the Stroop test, but poor-to-moderate ICC (ranging from 0.42 ­ 0.58) for the other cognitive assessments. In general, the participants reported good feasibility for the assessment format. CONCLUSION: In healthy and highly educated older adults, videoconferencing is a feasible method of determining functional and cognitive performance. Functional measures showed excellent reliability indexes, whereas cognitive data should be interpreted carefully, since the reliability varied from poor to moderate. (AU)


OBJETIVO: Nosso objetivo foi determinar a viabilidade e confiabilidade de medidas funcionais e cognitivas por meio de uma videoconferência baseada na web entre idosos no contexto da pandemia de COVID-19. METODOLOGIA: Trinta idosos [idade = 69,77 (desvio padrão ­ DP = 6,60) anos; 86,70% mulheres], que vivem de forma independente na comunidade (independente fisicamente e sem sinais de comprometimento cognitivo) participaram do estudo. Um avaliador independente e experiente entregou, em tempo real, avaliações funcionais (Chair Rise Test ­ CRT, Chair Stand Test, Sitting and Rising Test ­ SRT) e cognitivas (MoCA, Teste de Trilhas A e B, Stroop Test e Fluência Verbal) por meio da Plataforma Google Meet em dois dias não consecutivos. A confiabilidade das medidas foi analisada pelo Coeficiente de Correlação Intraclasse (CCI), teste t pareado ou análise de Wilcoxon e Bland-Altman. A viabilidade da avaliação foi examinada com o uso de um questionário padronizado de 14 itens. RESULTADOS: Todas as medidas de desempenho funcional demonstraram excelente confiabilidade intra-avaliador [CCI variando de 0,90 (intervalo de confiança ­ IC95% 0,78 ­ 0,95) para SRT e 0,98 (IC95% 0,96 ­ 0,99) para CRT]. Além disso, nossa análise mostrou níveis mistos de confiabilidade entre as medidas, enquanto o MoCA, Teste de Trilhas B e as fases Interferência e Leitura do Stroop Test tiveram excelente CCI (variando de 0,79 a 0,91) e as outras avaliações cognitivas com CCI ruim a moderado (variando de 0,42 a 0,58). Em geral, os participantes demonstraram boa viabilidade com o formato das avaliações. CONCLUSÃO: Em idosos saudáveis e com alta escolaridade, a videoconferência baseada na web é uma alternativa viável para determinar o desempenho funcional e medidas cognitivas. As medidas funcionais apresentaram excelentes índices de confiabilidade, enquanto os dados cognitivos devem ser interpretados com cautela, visto que atingiram índices de confiabilidade de ruim a moderado.

ABSTRACT

O estudo objetivou comparar diferentes estratégias de supervisão durante 12 semanas de um programa de exercícios domiciliares sobre a função cognitiva de idosos saudáveis. Foi realizado um ensaio clínico, no qual participaram idosos comunitários de ambos os sexos, que foram divididos em dois grupos com diferentes estratégias de supervisão: supervisionado virtualmente por videoconferências durante todas as sessões de treino, ou supervisionado por mensagens de texto. A intervenção para ambos os grupos consistiu em um programa ofertado por meio de vídeos-aula, com frequência de três sessões semanais e duração de 12 semanas. Os desfechos foram avaliados remotamente por videoconferência. Para avaliar a cognição global foi utilizado o Montreal Cognitive Assessment (MoCA) e para o controle inibitório o Stroop test. Foi feita uma análise inferencial, com intenção de tratar, de modelos mistos por simetria composta, considerando intervalos de confiança (IC) a 95% e um nível de significância de 5%. Trinta e oito participantes foram randomizados e alocados em um dos grupos (81,6% mulheres, média de idade de 68,39 ± 6,48 anos, massa corporal média de 69,82 ± 12,15 kg, altura média de 1,59 ± 0,06 m, índice de massa corporal médio de 27,82 ± 4,88 kg/m²; e 94,7% com mais de 12 anos de estudo). Não houve diferenças estatisticamente entre os grupos (p>0,05) e não foram observados efeitos ao longo do tempo nas comparações intra-grupos (p>0,05). Concluiu-se que a supervisão utilizada neste estudo não promove ganhos cognitivos adicionais ao programa de exercícios domiciliares supervisionado por mensagens de texto em idosos saudáveis.


The study aimed to compare different supervision strategies during 12 weeks of a home exercise program on the cognitive function of healthy older adults. A clinical trial was conducted in which community-dwelling older adults of both genders participated. They were divided into two groups with different supervision strategies: those virtually supervised by videoconferences during all training sessions or those supervised by text messages. The intervention for both groups consisted of a program offered through video lessons, with a frequency of three weekly sessions and a duration of 12 weeks. Outcomes were assessed remotely via videoconference. The Montreal Cognitive Assessment (MoCA) was used to assess global cognition, and the Stroop test was used for inhibitory control. An intention-to-treat inferential analysis of mixed models by compound symmetry was performed, considering 95% confidence intervals (CI) and a significance level of 5%. Thirty-eight participants were randomized and allocated to one of the groups (81.6% women, mean age 68.39 ± 6.48 years, mean body mass 69.82 ± 12.15 kg, mean height 1.59 ± 0.06 m, mean body mass index of 27.82 ± 4.88 kg/m²; and 94.7% with more than 12 years of study). There were no statistically significant differences between groups (p>0.05), and no effects over time were observed in intra-group comparisons (p>0.05). It was concluded that both supervision methods used in this study did not provide additional cognitive gains to the home exercise program in healthy older adults.

ABSTRACT

Abstract Introduction: To establish a correlation between concern about falling and a more comprehensive functional parameter, functional muscle fitness, a variable that encompasses functional components such as balance, muscle strength, power, flexibility and motor coordination in an integrated way. Functional muscle fitness is measured using the sitting-rising (from the floor) test (SRT), a simple, safe, fast and ecological test. Objective: The aim of our study was to determine the correlation between concern about falling and functional muscle fitness in the elderly. Methods: A cross-sectional observational study was conducted. The sample consisted of 53 elderly people of both sexes (86.8% women; 65.6 ± 4.7 years old; body mass index 28.5 ± 3.8 kg/m2), who were assessed for concern about falling (through Falls Efficacy Scale International, FES-I-Brazil) and functional muscle fitness (through SRT). Correlation analysis was performed using the Spearman test. For all analyses, a significance level of 5% (p < 0.05) was established. Results: Concern about falling showed a negative correlation with functional muscle fitness (rho =-0.229; p = 0.015). Conclusion: Elderly people with lower levels of functional muscle fitness have a higher level of concern about falling.


Resumo Introdução: Com o intuito de estabelecer uma correlação entre a preocupação em cair e um parâmetro funcional mais abrangente, a aptidão muscular funcional, variável que engloba componentes funcionais como equilíbrio, força, potência muscular, flexibilidade e coordenação motora de forma integrada, surge como uma alternativa. A aptidão muscular funcional é mensurada por meio do teste de sentar e levantar do chão (TSL), um teste simples, seguro, rápido e ecológico. Objetivo: A pesquisa teve como objetivo verificar a correlação entre a preocupação em cair e a aptidão muscular funcional de idosos. Métodos: Trata-se de um estudo com delineamento observacional do tipo transversal correlacional. A amostra foi composta por 53 idosos de ambos os sexos (86,8% mulheres; 65,6 ± 4,7 anos; índice de massa corporal 28,5 ± 3,8 kg/m2), avaliados quanto à preocupação em cair (através da Escala Internacional de Eficácia de Quedas Brasil - FES-I-Brasil) e à aptidão muscular funcional (através do TSL). A análise de correlação foi realizada pelo teste de Spearman. Para todas as análises foi estabelecido um nível de significância de 5% (p < 0,05). Resultados: A preocupação em cair apresentou correlação negativa com aptidão muscular funcional (rho =-0,229; p = 0,015). Conclusão: Idosos com menores índices de aptidão muscular funcional apresentam maior nível de preocupação em cair.
