Key result
Wrist arterial pulse assessment revealed significant gender differences in pulse power index, pulse depth index, and spectral harmonic energy ratio across the Cun, Guan, and Chi positions.
Why the study?
Gender differences are recognized as important intrinsic factors in wrist arterial pulse assessment, motivating an examination of pulse waves and anatomical properties at three wrist positions.
Are there gender differences in wrist arterial pulse waves and anatomical properties in healthy adults?
Cross-Sectional (n=139)
Are there gender differences in wrist arterial pulse waves and anatomical properties in healthy adults?
Significant gender differences exist in wrist arterial pulse wave parameters and their correlation with anatomical properties, which should be considered in traditional pulse diagnosis.

Gender differences may require sex-specific pulse norms in diagnosis; cross-sectional data leaves open prospective validation.
Gender differences are important intrinsic factors in wrist arterial pulse assessment in traditional Chinese and Korean medicine. The current study aimed to examine gender differences in wrist pulse waves at the Cun, Guan, and Chi positions of the wrist and to identify associations between physical indices and anatomical properties at all three positions. One hundred thirty-nine middle-aged Korean men and women participated in this cross-sectional study. A blood analysis was performed, and blood pressure and medical history were recorded. Artery diameter and depth, blood flow velocity, and pulse wave were measured. The pulse power index (PPI), pulse depth index (PDI), and power spectrum density at the third harmonic frequency/first harmonic frequency (PSD_w3_w1) showed highly significant differences according to gender. Men exhibited larger PPI values than women at all three positions. The PDI and PSD_w3_w1 in men were higher at the Cun position than those in women, whereas the PDI at the Chi position was higher in women than in men. Gender differences in the spectral harmonic energy ratio were greater at the Guan and Chi positions than those at the Cun position. The subendocardial viability ratio differed significantly between genders. In women, the PDI was highly positively correlated with radial artery depth at all positions; however, in men, the PDI was only marginally correlated with artery depth at the Guan and Chi positions. We suggest that gender differences should be considered in wrist artery pulse diagnosis, including those related to pulse diagnostic positions and anatomical properties.

Lee et al. (2018) conducted a cross-sectional in Healthy adults (n=139). Wrist arterial pulse assessment vs. Men vs Women was evaluated on Gender differences in wrist pulse waves at the Cun, Guan, and Chi positions and associations with anatomical properties. Wrist arterial pulse assessment revealed significant gender differences in pulse power index, pulse depth index, and spectral harmonic energy ratio across the Cun, Guan, and Chi positions.
