To evaluate the effect of a single 10-minute session of Chinese head massage on the activity of the cardiac autonomic nervous system via measurement of heart rate variability (HRV).
In this pilot randomized crossover trial, each participant received both head massage and the control intervention in a randomized fashion.
SETTINGS/LOCATION: The study was conducted at Children's & Women's Health Centre of British Columbia between June and November 2014.
Ten otherwise healthy adults (6 men and 4 women) were enrolled in this study.
The intervention comprised 10 minutes of head massage therapy (HMT) in a seated position compared with a control intervention of sitting quietly on the same chair with eyes closed for an equal amount of time (no HMT).
The primary outcome measures were the main parameters of HRV, including total power (TP), high frequency (HF), HF as a normalized unit, pre-ejection period, and heart rate (HR).
A single short session (10 minutes) of head massage demonstrated an increase in TP continuing up to 20 minutes after massage and reaching statistical significance at 10 minutes after massage (relative change from baseline, 66% for HMT versus -6.6% for no HMT; p = 0.017). The effect on HF also peaked up to 10 minutes after massage (59.4% for HMT versus 4% for no HMT; p = 0.139). Receiving head massage also decreased HR by more than three-fold compared to the control intervention.
This study shows the potential benefits of head massage by modulating the cardiac autonomic nervous system through an increase in the total variability and a shift toward higher parasympathetic nervous system activity. Randomized controlled trials with larger sample size and multiple sessions of massage are needed to substantiate these findings.
通过测量心率变异性（HRV）来评估单次10分钟的中式头部按摩对心脏自主神经系统活动的影响。
在这项先导性随机交叉试验中，每位参与者以随机方式接受头部按摩和对照干预。
设置/地点：该研究于2014年6月至11月在不列颠哥伦比亚省儿童与妇女健康中心进行。
十名其他方面健康的成年人（6名男性和4名女性）参与了本研究。
干预包括10分钟的坐姿头部按摩疗法（HMT），与之相比的对照干预是坐在同一把椅子上安静地闭眼同等时长（无HMT）。
主要结果测量指标是HRV的主要参数，包括总功率（TP）、高频（HF）、归一化单位的HF、射血前期和心率（HR）。
单次短暂的（10分钟）头部按摩显示TP增加，按摩后持续至20分钟，并在按摩后10分钟达到统计学显著性（相对于基线的变化，HMT为66%，无HMT为-6.6%；p = 0.017）。对HF的影响在按摩后10分钟也达到峰值（HMT为59.4%，无HMT为4%；p = 0.139）。与对照干预相比，接受头部按摩还使HR降低了三倍多。
本研究表明，头部按摩通过增加总变异性和向更高的副交感神经系统活动转变来调节心脏自主神经系统，具有潜在益处。需要进行更大样本量和多次按摩疗程的随机对照试验来证实这些发现。
