Thirty borderline essential hypertensives were randomly assigned to a portable constant-cuff blood pressure feedback technique or meditation-relaxation. Each technique was taught in the laboratory, then practiced twice daily at home for four weeks. Subjects mailed daily records of their progress. Seven feedback and ten meditation-relaxation subjects completed the program. Both techniques produced significant systolic and diastolic reductions within practice sessions and diastolic reductions over weeks of training. Neither technique improved reductions nor reduced initial systolic pressure levels over the four weeks. Differences between biofeedback and meditation-relaxation in within-session pressure reductions were not significant.
30名临界原发性高血压患者被随机分配到便携式恒定袖带血压反馈技术组或冥想放松组。每种技术都在实验室进行教授，然后在家中每天练习两次，持续四周。受试者邮寄他们每日的进展记录。7名反馈组和10名冥想放松组受试者完成了该项目。两种技术在练习期间均使收缩压和舒张压显著降低，且在数周的训练中舒张压也有所降低。在四周内，两种技术均未改善血压降低幅度，也未降低初始收缩压水平。生物反馈和冥想放松在练习期间血压降低方面的差异不显著。
