Systematic Review (n=491)
Does Neiguan (PC6) stimulation stabilize blood pressure in various clinical and healthy populations?
Neiguan (PC6) stimulation may serve as an effective, non-pharmacological adjunctive treatment for stabilizing blood pressure and improving hemodynamics in both hypertensive and hypotensive conditions.
PC6 stimulation supports adjunctive BP stabilization in hypertension and hypotension; extends RCT evidence for bidirectional hemodynamic effects.
Objectives: This study reviewed randomized controlled trials (RCTs) investigating the effects of Neiguan (PC6) stimulation on blood pressure and suggests a better research process.Methods: We searched for RCTs for effects of Neiguan (PC6) stimulations on blood pressure published until July 2024 using six databases (PubMed, Oriental Medicine Advanced Searching Integrated System (OASIS), Korea Citation Index (KCI), Research Information Service System (RISS), Korean Studies Information Service System (KISS), and Science ON). In total, eight RCTs that met all the inclusion criteria were selected.Results: All the selected studies showed significant effects of Neiguan (PC6) stimulation on blood pressure. In most studies, Neiguan (PC6) stimulation was effective in stabilizing blood pressure and improving various indicators related to blood pressure.Conclusion: Neiguan (PC6) stimulation is an effective treatment for stabilizing blood pressure. However, the selected RCTs were short-term studies and had small number of subjects; so, long-term and large-scale studies are needed.

Kyung-min Baek (2024) conducted a systematic review in Blood pressure abnormalities (hypertension, hypotension) and healthy individuals (n=491). Neiguan (PC6) stimulation (acupuncture, acupressure, or TEAS) vs. Placebo, sham stimulation, or no treatment was evaluated on Blood pressure changes. Neiguan (PC6) stimulation effectively stabilized blood pressure and improved related hemodynamic indicators across all eight included randomized controlled trials.
