Association Between Protocols of the Sit-to-Stand Test and Lower Limb Muscle Force Output in Patients on Hemodialysis and Subjects Without Chronic Kidney Disease.

OBJECTIVE: To evaluate the association of three protocols of the sit-to-stand (STS) test with muscle force output of knee extension (KE) and knee flexion (KF) in patients on hemodialysis and subjects without chronic kidney disease. METHODS: This cross-sectional study included a hemodialysis group [n = 60, 59.5 (16.8) years, 55% female] and a control group [n = 60, 43.0 (11.8) years, 50% female]. The assessments were performed in 2 days, and the participants were submitted to three protocols of STS test (5-repetition STS, 10-repetition STS and 30-s STS) or muscle force output of the KE and KF evaluation by handheld dynamometer based on randomization. RESULTS: The hemodialysis group presented reduced muscle force output of the KE and KF, a longer time to perform the 5 STS and 10 STS tests, and a lower number of repetitions in the 30-s STS test. The three STS tests were associated with muscle force output of the KE in the hemodialysis group, in which the 10-repetition STS test showed the best association (R2 = 0.47; adjusted R2 = 0.42). However, the only association between the STS test and muscle force output of the KE in the control group was found in the 10-repetition STS test (R2 = 0.20; adjusted R2 = 0.13). CONCLUSIONS: The three protocols of STS tests were associated with muscle force output of the KE in patients on hemodialysis. However, the 10-repetition STS test was the best protocol to estimate the quadriceps muscle torque in these patients.

Exercise training during hemodialysis in Brazil: A national survey.

To evaluate the availability and characteristics of exercise training during hemodialysis in Brazil and to identify the reported barriers to exercise program implementation and maintenance. All dialysis units were assessed for eligibility using the database of the Brazilian Society of Nephrology. Each dialysis unit was contacted by telephone and the questions were administered. In dialysis units with exercise training, questions related to personnel involved, exercise components, and program delivery were included. Additionally, the barriers to exercise program implementation and maintenance were evaluated. This study included 261 dialysis units that responded to the survey. Forty-one dialysis units reported exercise training during hemodialysis in Brazil (prevalence of 15.7%). We identified 66 physiotherapists and 10 exercise physiologists in dialysis units with exercise training. Resistance training was the most common program component (92.7%). Hypotension (90.5%) and muscle cramps (85.7%) were the most common adverse events reported. In dialysis units with exercise training, poor patients' adherence to exercise was the most commonly reported barrier. The most prevalent barrier in dialysis units that tried or never tried to implement the exercise programs was a lack of resources. The number of dialysis units that have exercise training during hemodialysis in Brazil is low, and the most common program component is resistance training. A lack of resources was the most prevalent barrier in dialysis units that tried or never tried to implement the exercise programs.

Factors Associated with Functional Capacity in CKD Patients.

To evaluate the factors associated with functional capacity in patients with chronic kidney disease (CKD). All patients were submitted to six-minute walk test (6MWT), 10-repetition sit-to-stand test (STS-10) and SF-36 health-related quality of life questionnaire (HRQoL). Patients with functional capacity ≥80% exhibited higher education level, family income, body mass index, estimated glomerular filtration rate, and lower age and STS-10 time. Multiple linear regression showed that gender, age, family income, chronic kidney disease stage, STS-10 time, and physical component summary of HRQoL were significantly associated with the 6MWT distance. Functional capacity was significantly associated with gender, age, family income, CKD stage, STS-10 time, and physical component of HRQoL. The progression of CKD has an impact on the decrease in functional capacity in these patients.

Cuestionario PAR-Q & YOU y antecedentes cardiovasculares frente a la práctica de la actividad física en adultos mayores en diálisis / PAR-Q & YOU Questionnaire and cardiovascular history of elderly patients on dialysis engaged in physical activity

INTRODUCCIÓN: La actividad física se ha convertido en los últimos años en una herramienta terapéutica y mecanismo protector en el adulto mayor para disminuir el riesgo cardiovascular en usuarios con diversos tipos de diálisis que se encuentran en su fase paliativa. OBJETIVO: El presente trabajo buscó determinar la evaluación de ingreso a un programa de actividad física terapéutica por medio de la aplicación del Cuestionario PARQ & YOU en un grupo de participantes adultos mayores con diversos tipos de hemodiálisis, y su relación con los factores de riesgo cardiovascular. MATERIAL Y MÉTODOS: Se utilizó una prueba chi cuadrado de Pearson con el fin de determinar la posible asociación de las variables en relación a los antecedentes médicos y el disconfort, frente a la práctica de actividad física versus el resultado del PAR-Q & YOU. Se realizó una regresión logística binaria con las variables que en el análisis mediante prueba chi cuadrado. CONCLUSIONES: En la regresión logística se evidenció que los antecedentes cardiovasculares tienen 10.44 más veces influencia sobre la pertinencia de la aplicación del PAR-Q & YOU, como un instrumento básico para el ingreso a programas de actividad física en la rehabilitación renal desde la fisioterapia

INTRODUCTION: During the last few years, physical activity has become a therapeutic tool and a protective mechanism for the elderly; it reduces cardiovascular risk in patients undergoing different types of dialysis and receiving palliative care. OBJECTIVE: The aim of this study was to establish the inclusion criteria for a therapeutic physical activity program through the use of the PAR-Q & YOU Questionnaire with elderly patients treated with different types of hemodialysis, and to relate it with cardiovascular risk factors. METHODS:Pearson's chi-squared test was used to determine the possible association among variables, considering the medical history and discomfort caused by physical activity against the results of PAR-Q & YOU. Binary logistic regression was used with the variables in the chi-squared test. CONCLUSIONS: Through logistic regression, we found that cardiovascular history was 10.44 times more significant to establish the relevance of the PAR-Q & YOU as a basic assessment instrument for the inclusion in a physical activity program which is part of a physiotherapy-led renal rehabilitation
