Abstract

|
Objectives : The aim of this study was to assess the quantitative characteristics of pressure pain threshold (PPT) and pressure depth (PD) at the abdominal conception vessel (CV) acupoints according to subjective digestive status and digestive discomfort levels, accomplished by comparing a large group of healthy men and women, using the modified digital algometer.
Methods : A total of 1,504 healthy adults aged 19 years or older participated in this study. A questionnaire was administered to evaluate participants’ digestive status and discomfort. PPT (kgf/cm2/s) and PD (mm) measurements were obtained at CV14, CV12, and CV4 acupoints using a modified digital algometer. General characteristics were analyzed using the chi-square test, and differences in PPT and PD were assessed using two-sample t-tests and ANCOVA.
Results : Significant difference in PPT was found based on digestive status at CV14 and CV12 for both sexes, and in PD at CV14 for women. Women exhibited significant difference in PPT based on digestive discomfort at CV14, CV12, and CV4, while men showed significant difference at CV14 and CV12. Significant difference in PD was observed at CV14 and CV4 among women. Even after adjusting for age and body mass index, significant difference persisted in PPT based on digestive discomfort at CV14 and CV12 for both sexes. PD exhibited significant differences at CV14, CV12, and CV4 among women.
Conclusions : Using the modified digital algometer, this study showed the significant difference of pressure pain threshold at the CV14 and CV12 acupoints for subjective digestive discomfort levels in healthy men and women.
