Transcutaneous Electrical Acupoint Stimulation on Blood Pressure

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.

Treatment and study plan

Transcutaneous electrical acupoint stimulation

Device

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.

Sham stimulation

Device

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.

Primary outcomes

  1. Change in office systolic blood pressure between the third day after TEAS treatment and the baseline (before the start of treatment on the first day)

    Time frame: At the third day after TEAS treatment and the baseline (before the start of treatment on the first day)

Secondary outcomes

  1. Changes in office systolic blood pressure at other time points before and after treatment

    Time frame: At all other time points (excluding the third day after treatment) and the baseline (before the start of treatment on the first day)

  2. Changes in office diastolic blood pressure at various time points before and after treatment

    Time frame: At each time point before and after treatment and the baseline (before the start of treatment on the first day).

  3. Changes in ambulatory blood pressure before and after treatment

    Time frame: At the third day after the end of treatment and the baseline (before the start of treatment on the first day)

  4. Changes in Hamilton Scale scores before and after treatment

    Time frame: At the third day after the end of treatment and the baseline (before the start of treatment on the first day)
