Desempenho muscular, dor, rigidez e funcionalidade de idosas com osteoartrite de joelho

Abstract

Objective: To determine the correlation between performance of the knee muscles and pain, stiffness, and functionality, through the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Questionnaire applied to an elderly population with osteoarthritis of the knee (OA). Methods: This study uses an observational, cross-sectional approach applied to a convenience sample of 80 elderly individuals (71.2 ± 5.3 years of age) with a clinical diagnosis of OA of the knee. Muscle strength, resistance, and balance of the knee were evaluated using the Biodex System 3 Pro isokinetic dynamometer at angular speeds of 60º/s and 180º/s. The self-reported functionality, presence of pain, and stiffness were evaluated by the WOMAC questionnaire. The correlation between the variables was analyzed by Spearman's coefficient of correlation (α = 0.05). Results: A significant inverse Acta Ortop Bras. 2011;19(4): 193-7All the authors declare that there is no potential conflict of interest referring to this article. correlation was observed between muscle strength and resistance of the quadriceps muscle (Q) and the hamstring muscle (H) at speeds of 60º/s and 180°/s, respectively, as well as in the relation between H/Q muscle balance at 180°/s and all domains of the WOMAC (p<0.05). Conclusions: The reduction in strength, resistance, and presence of imbalance in the knee muscles are inversely correlated with all the domains of the WOMAC in elderly individuals with OA. These results indicate a need for intervention that involves strengthening, resistance, and balance of the knee extensor and flexor muscles, aimed at reducing the impact of OA in relation to pain, stiffness, and functionality in elderly individuals. Level of Evidence: Level I, diagnostic studies -investigating a diagnostic test. ORiginAl ARticle

Quality of life and functional capacity of elderly women with knee osteoarthritis

“…In addition, previous studies were heterogenous with regard to use of WOMAC ( 2 , 12 – 15 ) , which poses difficulties for comparison with our data. Most of our patients reported moderate pain, a finding that agrees with some previous studies ( 11 , 14 ) but not with others ( 13 , 15 ) .…”

“…The age of the studied population differed from that in studies from other countries ( 9 , 10 ) in that our study included only women 60 years of age or older; however, this study population is similar to that in other Brazilians' studies ( 2 , 11 ) .…”

Métodos fisioterapêuticos utilizados na reabilitação do equilíbrio postural em indivíduos com osteoartrite: uma revisão sistemática

“…Nessa perspectiva, um estudo com 33 indivíduos com OA de joelho foram submetidos a exercícios de fortalecimento muscular, treino de propriocepção, equilíbrio e agilidade (G1=8), treino de resistência física (G2=9), a combinação dos dois protocolos anteriores (G3) e massagem articular (G4 ou GC). Após 24 sessões, o G1, G2 e G3 apresentaram aumento da funcionalidade 19,20 , especialmente o G3 21 . Reforçando as evidências de que os indivíduos com OA sejam beneficiados através da cinesioterapia ativa dos tecidos e que a melhora da funcionalidade do membro inferior esteja correlacionada com a melhora do EP nesta população.…”

Muscle performance, body fat, pain and function in the elderly with arthritis

“…However, the small sample size may have also influenced this analysis. Santos et al 5 . evaluated 80 elderly patients (71.2 ± 5.3 years) with clinical diagnosis of knee OA and found an inverse correlation between all domains of the WOMAC and isokinetic muscle strength of knee extensors and flexors, suggesting that the individuals evaluated had reduced muscle strength and a negative impact in the areas of pain, stiffness and mainly joint function.…”
