心率变异性生物反馈（HRV-BF）被用作心身医学中的一项技能，但在睡眠领域尚未建立。本研究旨在评估每2周进行一次的共振频率呼吸（RFB）对睡眠的影响，以及在睡前使用便携式设备在家中练习RFB的有用性。参与者是69名癌症患者的家庭照顾者，他们感到护理负担沉重。我们进行了一项随机对照试验，其中包括HRV-BF+家庭实践组和HRV-BF组。在实验当天，在我们的医疗机构对两组进行了长达30 min的RFB HRV-BF。家庭实践涉及使用便携式设备的RFB，每天在睡前20分钟内在家中进行。评价项目为：试验开始后28 d匹兹堡睡眠质量指数（PSQI）总分变化率。总的来说，52.2%的参与者患有失眠症。两个HRV-BF组的PSQI总分降低，表明第28天PSQI总分改善接近5.5。两组HRV评分在第28天均显著升高，且PSQI总分变化与HRV评分变化相关。第28天，与HRV-BF组相比，HRV-BF+家庭练习组通过PSQI评分评估的睡眠质量显著改善（p = 0.001）。这表明HRV-BF可能是一种有用的技能，可以增强癌症患者家庭照顾者的睡眠，以及支持他们的自主神经功能。额外的RFB实际定期实践（睡前在家里使用便携式设备）可能会进一步增强效果。
Heart rate variability biofeedback (HRV-BF) is used as a skill in psychosomatic medicine, but is not yet established in the field of sleep. The present study aimed to evaluate the effect of HRV-BF with resonant frequency breathing (RFB) on sleep performed once every 2 weeks and the usefulness of practice of RFB using a portable device at home before bedtime. Participants were 69 family caregivers of patients with cancer that felt burdened by nursing care. We conducted a randomized controlled trial with an HRV-BF+Home practice group and an HRV-BF group. HRV-BF with RFB was administered to both groups at our medical institution for up to 30 min on the experiment days. Home practice involved RFB using a portable device, which was performed at home each day within 20 min before bedtime. Evaluation items were: change ratio of total score of the Pittsburgh Sleep Quality Index (PSQI) at 28 days after the trial started. In total, 52.2% of participants had insomnia. The two HRV-BF groups had decreased PSQI total scores, which indicated an improvement in PSQI total score near 5.5 on Day 28. The two HRV-BF groups had significantly increased HRV scores on Day 28, and there was correlation between the variation of PSQI total score and the variation of HRV score. The quality of sleep assessed by PSQI scores in the HRV-BF+Home practice group was significantly improved compared with the HRV-BF group on Day 28 (p = 0.001). This suggests HRV-BF may be a useful skill for enhancing sleep among family caregivers of patients with cancer, as well as supporting their autonomic nervous function. Additional actual regular practice of RFB (using a portable device at home before bedtime) may further enhance the effect.
