Abstract

OBJECTIVE

To investigate the reliability of an aerobic and an anaerobic exercise test in patients with juvenile dermatomyositis (JDM).

METHODS

Sixteen patients with JDM (mean age 13.85 +/- 6.4 yrs, range 6.7-27.2) participated. Anaerobic exercise capacity was measured using the Wingate Anaerobic Exercise Test (WAnT). Aerobic exercise test was performed using a graded exercise test to volitional exhaustion on an electronically braked cycle ergometer. Patients were tested and retested within 12.8 +/- 5.7 days.

RESULTS

Correlation coefficients and other reliability statistics indicated that peak power and mean power on the WAnT and peak oxygen uptake (VO2peak) and maximal workload (Wmax) on the aerobic exercise test could be reliably assessed in patients with JDM. Pearson (R) and intraclass correlation coefficients (ICC) were > 0.85, and typical error was < 20% for the peak power and mean power on the WAnT. On the aerobic exercise test the R and ICC were > 0.95, and typical error was < 6% for the VO2peak and Wmax.

CONCLUSION

We found acceptable reliability for the WAnT and very good reliability for the aerobic exercise test. This indicated that these exercise tests could be performed reliably in patients with JDM.

摘要

目的

探讨有氧运动试验和无氧运动试验在青少年皮肌炎（JDM）患者中的可靠性。

方法

16例JDM患者（平均年龄13.85±6.4岁，范围6.7 - 27.2岁）参与研究。使用温盖特无氧运动试验（WAnT）测量无氧运动能力。采用电子制动自行车测力计进行递增运动试验至自愿疲劳，以进行有氧运动试验。患者在12.8±5.7天内进行了测试和复测。

结果

相关系数和其他可靠性统计表明，JDM患者的WAnT峰值功率和平均功率以及有氧运动试验中的峰值摄氧量（VO2peak）和最大工作量（Wmax）能够得到可靠评估。WAnT的Pearson（R）和组内相关系数（ICC）>0.85，峰值功率和平均功率的典型误差<20%。在有氧运动试验中，R和ICC>0.95，VO2peak和Wmax的典型误差<6%。
