Physical therapy during hemodialyse in patients with chronic kidney disease.

INTRODUCTION: The aim of this study was to evaluate the effects of a physical therapy program in patients with chronic kidney disease (CKD) during hemodialysis (HD). METHODS: Fifty-six CKD patients participated for 16 months in a supervised physical therapy program in HD sessions. They underwent evaluation before the start of the program and 16 months after this training. The program consisted of muscle strengthening exercises, stretching and stationary exercise bike. The analysis is composed of test six-minute walk (6MWT), level of effort by the BORG scale test of one repetition maximum (1RM) to measure the quadriceps strength, quality of life (QOL) and arterial blood pressure (BP), heart (HR) and respiratory (RR). RESULTS: The results showed an increase in distance traveled for the 6MWT and quadriceps strength, reduction of HR and RR and improvement in total score SF-36, but significantly in functional capacity and pain BP reduced, though not significantly. It was found by the Spearman correlation test, only in the areas correralation pain and functional capacity, individually, with the increase in distance walked in 6MWT; correlation between decreases in HR and RR linked to reduction in the Borg scale. CONCLUSION: Physical therapy, through an exercise program during the intradialytic period, can provided a significant improvement of QOL and physical ability of patients with CKD.

Fisioterapia durante a hemodiálise de pacientes com doença renal crônica / Physical therapy during hemodialyse in patients with chronic kidney disease

INTRODUÇÃO: O objetivo do estudo foi avaliar os efeitos de um programa de fisioterapia em pacientes com doença renal crônica (DRC) durante a hemodiálise (HD). MÉTODOS: Cinquenta e seis pacientes com DRC participaram, durante 16 meses, de um programa de fisioterapia supervisionado nas sessões de HD. As avaliações ocorreram antes e 16 meses após o início do treinamento. O programa consistiu de exercícios de fortalecimento muscular, alongamento e bicicleta ergométrica estacionária. As análises se compuseram de teste de caminhada de seis minutos (TC6M); nível de esforço pela escala de BORG, teste de uma repetição máxima (1RM), para mensurar a força muscular de quadríceps; qualidade de vida (QV) e medidas de pressão arterial (PA), frequências cardíaca (FC) e respiratória (FR). RESULTADOS: Houve aumento na distância percorrida (54 m; p < 0,001) pelo TC6M e da força muscular de quadríceps (média de +3 para +4; p < 0,001); redução da FC e FR (média de 8 bpm e 5 irpm, respectivamente; p < 0,001); melhora no escore total da SF-36 (p < 0,006), porém significativamente na capacidade funcional (p < 0,006) e dor (p < 0,001). A PA reduziu, entretanto, não significativamente (p < 0,08). Verificou-se correlação apenas nos domínios dor e capacidade funcional, individualmente, com o aumento da distância percorrida no TC6M (p < 0,013 e p < 0,002); houve correlação entre diminuições na FC e FR, atreladas à redução na escala de BORG (p < 0,043). CONCLUSÃO: A fisioterapia, por meio de um programa de exercícios físicos durante o período intradialítico, pode proporcionar melhora significativa da QV e capacidade física dos pacientes com DRC.

Artroplastia glenoumeral: resistência do fio de poliéster após contato com o metilmetacrilato / Glenoumeral arthroplasty: polyester properties after methyl methacrylate contact

OBJETIVO: Os autores estudam as características do fio de poliéster (ethibond) após o contato com o metilmetacrilato (cimento ortopédico) no laboratório de resistência de materiais. MÉTODOS: Avaliam a força necessária para a ruptura bem como a elasticidade e a deformidade provocadas durante a tração no aparelho Instron 4482. Realizam análise estatística através do teste "t-student". RESULTADOS: Não encontram diferença estatisticamente significativa entre os grupos estudados. CONCLUSÃO: Concluem que o contato do metilmetacrilato com o poliéster não acarreta mudanças na suas propriedades elásticas e de resistência à tração.

OBJECTIVE: The authors studied the physical properties of polyester thread (ethibond) following methyl methacrylate contact in a biomechanics laboratory. METHODS: Strain at rupture, elasticity and traction deformity were evaluated using an Instron 4482 machine. The student-t test was used for the statistical analysis. RESULTS: There were no statistical differences between the two groups. CONCLUSION: It is concluded that methy metacrylate contact with polyester does not affect its elastic properties and traction resistance.
