Relationship Between Lower Limb Muscle Strength and Future Falls Among Community-Dwelling Older Adults With No History of Falls: A Prospective 1-Year Study

Abstract

Objective: To investigate whether lower limb muscle strength could be a risk factor for the first fall among nonfaller community-dwelling older adults. Method: Hip, knee, and ankle peak torque (PT) was measured with an isokinetic dynamometer in 101 older adults with no history of falls in the previous year. Next, the authors followed up the participants on a monthly basis by telephone contact to determine the occurrence of fall episodes over a period of 1 year. Multivariate logistic regression adjusted for confounding variables was applied to assess the relationship between falls and lower limb PT. Results: there was no association between lower limb PT and future falls ( p > .05). Conclusion: Based on these results, it is important to identify other factors that predispose older adults with no history of falls to falling for the first time, so that early and effective preventive strategies may be elaborated.

The Association Between Sarcopenia and Postoperative Outcomes Among Older Adults With Hip Fracture: A Systematic Review

“…It is challenging to determine a causeand-effect relationship between sarcopenia and hip fracture. A recent observational prospective study concluded that lower limb muscle strength (hip, knee, and ankle) was not directly related to a fall among community-dwelling older adults (Porto et al, 2021), whereas others have reported significant correlations (Elhakeem et al, 2019;Yang et al, 2018). Furthermore, severe muscle mass wasting in both injured and intact legs after hip fracture may contribute to increased sarcopenia proportions (Chi et al, 2016;Ogawa et al, 2008).…”

Classificação do Risco de Quedas em Idosos com Least Squares Support Vector Regression Utilizando Sinais Eletromiográficos e Dinamométricos

“…Isso levanta a hipótese de que o torque talvez não tenha um protagonismo tão sólido na manutenção do equilíbrio quanto se pensava. De fato, um estudo recente prospectivo não identificou associação entre a força muscular do membro inferior dominante e a ocorrência de quedas futuras entre idosos que até então não possuíam histórico de quedas, de forma que é importante identificar outros fatores que possam contribuir para o primeiro episódio de desequilíbrio [22]. Contudo, há também a possibilidade de que os atributos considerados sejam mais apropriados para os sinais de EMG que para os sinais de força.…”

The relationship between common foot problems with falls and quality of life in older people

“…In the current study, the relationship between plantar and dorsiflexor strength and TUG test time were extremely close. However, in a very recent study by Porto et al(Porto et al, 2020), lower limb muscle strength (including plantar and dorsiflexors) was not directly related to the occurrence of the first fall among older people.In spite of the results obtained in other studies, this study revealed neither a significant effect of hallux valgus on quality of life nor a relationship with falls.…”
