Introdução : a osteoartrite é uma doença articular inflamatória e degenerativa que acomete principalmente os joelhos, sobretudo em idosos. Objetivo: verificar os efeitos da cinesioterapia na osteoartrite de joelho em idosos. Métodos: realizou-se uma revisão sistemática nas bases de dados SciELO, LILACS, Cochrane Library e MEDLINE, onde cruzaram-se os descritores “Osteoartrite”, “Fisioterapia”, “Exercício”, “Terapia por exercício” e “Idoso”, nas línguas portuguesa, inglesa e espanhola, considerando-se os artigos originais publicados entre 2010 e 2016. Resultados: encontraram-se 594 artigos. Inicialmente 62 artigos potencialmente relevantes foram selecionados para o estudo. Após uma análise qualitativa cri - teriosa, selecionaram-se 06 artigos completos que preencheram os critérios de inclusão exigidos, cujos mesmos foram analisados por meio da Escala PEDro. Conclusão: a cinesioterapia (aquecimento, alongamento dos músculos posteriores da coxa e fortalecimento dos músculos anteriores da coxa), com frequência de duas vezes por semana, em um período de seis a 12 semanas, parece ser benéfica para melhorar o desempenho muscular, funcionalidade, diminuir a dor e rigidez em idosos com osteoartrite de joelho, sem a necessidade de recursos adicionais.
The purpose of this study was to verify the accuracy of the agreement between heart rate at the first ventilatory threshold (HRVT1) and heart rate at the end of the 6-min walk test (HR6MWT) in coronary artery disease (CAD) patients on β-blockers treatment. This was a cross-sectional study with stable CAD patients, which performed a cardiopulmonary exercise test (CPET) on a treadmill and a 6-min walk test (6MWT) on nonconsecutive days. The accuracy of agreement between HRVT1 and HR6MWT was evaluated by Bland–Altman analysis and Lin’s concordance correlation coefficient (rc), mean absolute percentage error (MAPE), and standard error of estimate (SEE). Seventeen stable CAD patients on β-blockers treatment (male, 64.7%; age, 61± 10 years) were included in data analysis. The Bland–Altman analysis revealed a negative bias of -0.41 ± 6.4 bpm (95% limits of agreements, -13 to 12.2 bpm) between HRVT1 and HR6MWT. There was acceptable agreement between HRVT1 and HR6MWT (rc = 0.84; 95% confidence interval, 0.63 to 0.93; study power analysis= 0.79). The MAPE of the HR6MWT was 5.1% and SEE was 6.6 bpm. The ratio HRVT1/HRpeak and HR6MWT/HRpeak from CPET were not significantly different (81%± 5% vs. 81%± 6%, P= 0.85); respectively. There was a high correlation between HRVT1 and HR6MWT (r= 0.85, P< 0.0001). Finally, the results of the present study demonstrate that there was an acceptable agreement between HRVT1 and HR6MWT in CAD patients on β-blockers treatment and suggest that HR6MWT may be useful to prescribe and control aerobic exercise intensity in cardiac rehabilitation programs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
