Abstract

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 (R = 0.47; adjusted R = 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 (R = 0.20; adjusted R = 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.

摘要

目的

评估三种坐-站（STS）测试方案与血液透析患者和无慢性肾脏病患者的膝关节伸展（KE）和膝关节屈曲（KF）肌肉力量输出的相关性。

方法

这项横断面研究纳入了血液透析组（n=60，59.5（16.8）岁，55%女性）和对照组（n=60，43.0（11.8）岁，50%女性）。评估在两天内进行，参与者随机接受三种 STS 测试方案（5 次重复 STS、10 次重复 STS 和 30 秒 STS）或使用手持测力计进行 KE 和 KF 肌肉力量输出评估。

结果

血液透析组的 KE 和 KF 肌肉力量输出降低，5 次重复 STS 和 10 次重复 STS 测试完成时间延长，30 秒 STS 测试重复次数减少。三种 STS 测试均与血液透析组的 KE 肌肉力量输出相关，其中 10 次重复 STS 测试相关性最好（R=0.47；调整 R=0.42）。然而，在对照组中，仅在 10 次重复 STS 测试中发现 STS 测试与 KE 肌肉力量输出之间存在关联（R=0.20；调整 R=0.13）。
