[Discussion on the commonalities of scalp acupuncture schools and the feasibility of a unified scalp acupuncture protocol].

The data of 44 scalp acupuncture schools are collected to analyze their commonalities in theoretical foundations, needling sites, techniques, and indications. The integration of these characteristics into an optimized, unified scalp acupuncture protocol has become an inevitable trend. The paper discusses the potential for a unified scalp acupuncture protocol from aspects such as theoretical unification, the relationships between point areas, lines, and sites, and needle numbers.
