OBJECTIVES
To determine whether a 15-minute, one-time guided relaxation program for cancer patients could improve symptom distress as measured by the Edmonton Symptom Assessment System (ESAS). In addition, we were interested in characterizing the changes of the autonomic nervous system, as demonstrated by heart rate variability (HRV) high-frequency (HF) spectral analysis, before and after this relaxation program.
DESIGN
Nonrandomized pilot study.
SETTING
Comprehensive cancer center.
METHODS
Twenty cancer patients underwent a 15-minute relaxation program. The ESAS and a 5-minute HRV recording were completed before and after the relaxation program.
MAIN OUTCOME MEASURES
The differences between the pre- and post-summed ESAS score and HRV values were compared by a paired t-test.
RESULTS
The summed ESAS scores were significantly lower after the relaxation program (P<.01), with an average 31% decrease in total score. However, no differences were found in HRV HF power. There was no correlation between the change in HRV HF and change in symptom distress, as measured by ESAS.
CONCLUSIONS
A brief guided relaxation program can significantly improve symptoms as measured by ESAS. More research is required to understand the effects of relaxation on HF HRV power.
目的
确定是否可以通过 15 分钟的一次性指导放松程序来改善癌症患者的症状困扰，该程序通过埃德蒙顿症状评估系统（ESAS）进行测量。此外，我们还对自主神经系统的变化很感兴趣，这种变化通过心率变异性（HRV）高频（HF）谱分析来进行描述，这是在该放松程序之前和之后进行的。
设计
非随机试验研究。
设置
综合性癌症中心。
方法
20 名癌症患者接受了 15 分钟的放松程序。在放松程序前后，完成 ESAS 和 5 分钟 HRV 记录。
主要观察指标
通过配对 t 检验比较放松程序前后 ESAS 总分和 HRV 值的差异。
结果
放松程序后 ESAS 总分显著降低（P<.01），总分平均降低 31%。然而，HRV HF 功率没有差异。HRV HF 的变化与 ESAS 测量的症状困扰的变化之间没有相关性。
结论
简短的指导放松程序可以显著改善 ESAS 测量的症状。需要进一步的研究来了解放松对 HF HRV 功率的影响。
