Abstract Background Hypertension is a major pathogenic factor of cardiovascular diseases. Insufficient blood pressure control rate and sub-optimal medication adherence remain challenges for effective management of hypertension. Transcutaneous electrical acupoint stimulation (TEAS) has been used to treat various diseases, including hypertension, but the scientific evidence for its benefit remains insufficient. Therefore, we will perform a randomized, controlled clinical trial in patients with stage 1 hypertension to evaluate the effect of TEAS. Methods/design The study will be a two-arm parallel, randomized controlled trial. Sixty patients with stage 1 hypertension will be randomly assigned to the TEAS group and the control group in a 1:1 ratio. The participants in the TEAS group will receive non-invasive acupoint electrical stimulation for 30 min at four acupoints in the upper and lower extremities at home, 4 times weekly for 12 weeks for a total of 48 sessions. Participants in the control group will not receive any form of acupoint stimulation. All participants in both groups will receive lifestyle education on how to control high blood pressure, including diet, weight control, and exercise. The primary outcome measure will be the change of the mean systolic blood pressure from baseline to 12 weeks. Secondary outcomes include the change of mean diastolic blood pressure, quality of life, body mass index, and physical activity level. Discussion This pilot, randomized, controlled trial will explore the feasibility of TEAS. It will also provide potential clinical evidence for the efficacy and safety of TEAS in the treatment of patients with stage 1 hypertension. The results of this study will be published in peer-reviewed journals. Furthermore, this pilot trial as the precursor of a large scale randomized controlled trial will inform the sample size of the subsequent trial.
