Hypertension
Conditions
Brief summary
This study will be conducted in patients with high-normal blood pressure and grade 1 hypertension and will be divided into two phases. In Phase One, a small group of patients will undergo transcutaneous electrical acupoint stimulation treatment for three consecutive days. Blood pressure changes will be observed before and after each stimulation session, as well as 1 hour, 3 hours, and 5 hours after stimulation, during the night of the treatment day, and the next morning. Phase Two will be a single-center, single-blind, parallel randomized controlled trial. After screening, patients will be randomly assigned to either the stimulation experimental group or the sham stimulation control group. For three consecutive days, both groups will receive their respective interventions at the same time each day, and their blood pressure changes will be recorded.
Interventions
DEVICETranscutaneous electrical acupoint stimulation
Participants will receive proper transcutaneous electrical acupoint stimulation treatment for three consecutive days. Each day, the selected five target acupoints (Renying, Quchi, Taichong, Zusanli, and Hegu) will be stimulated in rotation. Each acupoint will be stimulated once a day for 10 minutes, with a 2-minute interval between each acupoint, totaling 60 minutes. Throughout the trial, the stimulation parameters for each participant will remain constant, and the treatment will begin between 8:00 and 10:00 AM each day.
DEVICESham stimulation
Participants will receive sham stimulation treatment, where the left-side skin near the selected five target acupoints (avoiding other functional acupoints) will be stimulated in rotation. The stimulation time and method will be the same as in the experimental group. Throughout the trial, the stimulation parameters for each participant will remain constant, and the treatment will begin between 8:00 and 10:00 AM each day.

Masking description
At the time of enrollment, each participant will be assigned a unique identification number (e.g., 001). The coded information will be stored in a secure database accessible only to designated members of the research team. A random number table will be generated using SPSS software, and participants will be allocated to either the stimulation experimental group or the sham stimulation control group according to the generated random numbers. Randomization information will be strictly confidential, ensuring that participants, outcome assessors, and statistical analysts are all blinded to the group assignments.
