The purpose of the study was to examine the effectiveness of P6 acupressure on nausea associated with visually-induced motion sickness.
There were 64 subjects randomly divided into 4 groups: P6 acupressure, dummy-point acupressure, sham P6 acupressure, and control. Each subject sat in an optokinetic drum for a 12-min baseline and 12-min drum rotation period. Subjects' electrogastrograms (EGG's) and subjective symptoms of motion sickness were obtained.
The results indicated that the subjects in the P6 acupressure group reported significantly less nausea [F(3,60) = 8.16, p < 0.0001] during drum rotation period than those in the dummy-point acupressure, sham acupressure, and control groups. The scores for symptoms of motion sickness of the P6 acupressure group were significantly lower than those in the sham acupressure and control groups [F(3,60) = 3.49, p < 0.02]. Also, the subjects in the P6 acupressure group showed significantly less abnormal gastric myoelectric activity, tachyarrhythmia, than those in the sham acupressure and control groups [F(3,60) = 2.78, p < 0.04]. However, the subjects in the dummy-point acupressure group did not report significantly fewer symptoms and show less tachyarrhythmia than those in the sham acupressure and control groups.
We conclude that P6 acupressure reduces the severity of symptoms of visually-induced motion sickness and gastric tachyarrhythmia.
本研究旨在探讨内关穴指压对视觉诱发晕动病相关恶心的疗效。
64名受试者被随机分为4组：内关穴指压组、假穴指压组、假内关穴指压组和对照组。每位受试者坐在视动鼓中，进行12分钟的基线期和12分钟的鼓旋转期。记录受试者的胃电图（EGG）和晕动病主观症状。
结果表明，在鼓旋转期，内关穴指压组受试者报告的恶心程度[F(3,60)=8.16，p<0.0001]显著低于假穴指压组、假内关穴指压组和对照组。内关穴指压组的晕动病症状评分显著低于假内关穴指压组和对照组[F(3,60)=3.49，p<0.02]。此外，内关穴指压组受试者的胃肌电活动异常、快速心律失常显著少于假内关穴指压组和对照组[F(3,60)=2.78，p<0.04]。然而，假穴指压组受试者报告的症状和快速心律失常并不显著少于假内关穴指压组和对照组。
我们得出结论，内关穴指压可减轻视觉诱发晕动病症状的严重程度和胃快速心律失常。
