Summary

This study focuses on individuals with primary hypertension, with the main objective of investigating the effectiveness and safety of high-intensity transcranial alternating current stimulation (Hi-tACS) as a non-invasive, non-pharmacological treatment for hypertension

Conditions

  • Primary Hypertension

Interventions

DEVICE

Active High-Intensity Transcranial Alternating Current Stimulation (Hi-tACS)

Active Hi-tACS delivered using a transcranial alternating current stimulation device. Parameters: 77.5 Hz sinusoidal alternating current, 15 mA (peak-to-peak), 40 minutes per session. Electrode montage: one 8 cm × 4 cm electrode placed horizontally on the forehead (covering Fpz, Fp1, Fp2 regions) and two 6 cm × 2.9 cm electrodes placed on bilateral mastoid regions. Conductive gel ensures impedance \<10 kΩ. One session/day, 5 days/week for 4 weeks (total 20 sessions).

DEVICE

Sham High-Intensity Transcranial Alternating Current Stimulation (Hi-tACS)

Sham stimulation using the same device and electrode placement as the active arm. Active stimulation is applied only for the first 30 seconds, then ramped down to 0 mA over 10 seconds. For the remaining session duration, intermittent low-intensity signals producing imperceptible skin sensation are delivered to maintain blinding. Same schedule: 40 minutes/session, one session/day, 5 days/week for 4 weeks (total 20 sessions).
