Abstract Background High-normal blood pressure (BP) is associated with increased all-cause, cardiovascular mortality and frequently progresses to hypertension. Transcutaneous electrical acupoint stimulation (TEAS) might be a non-pharmaceutical therapy option to control BP. This trial aims to determine the effectiveness and safety of TEAS combined with lifestyle modification for high-normal BP. Methods/design This prospective, randomized, and parallel clinical trial will be conducted in a community service center in China. Sixty participants with high-normal BP will be randomly allocated to receive TEAS plus lifestyle modification (intervention group) or lifestyle modification alone (control group) in a 1:1 ratio. In addition to lifestyle modification, the intervention group will receive TEAS at four acupoints for 30 min, 4 times weekly for 12 weeks for a total of 48 sessions at home. The control group will receive same lifestyle modification but no TEAS. The primary outcome will be the change in mean systolic blood pressure at 12 weeks from the baseline measurement. Secondary outcomes include the change of mean diastolic blood pressure, proportion of subjects with progression to hypertension, quality of life, body mass index, and waist circumference. Adverse events during the trial will be monitored. Discussion This trial will explore the feasibility and provide potential evidence for the effectiveness and safety of TEAS plus lifestyle modification for high-normal BP. Furthermore, this pilot trial is being undertaken to determine the feasibility of a full scale definitive randomized controlled trial. The results of this study will be published in a peer-reviewed journal. Trial registration Chinese Clinical Trial Registry, ChiCTR 1900024982 . Registered on August 6, 2019.
