Pulse Wave Variation during the Menstrual Cycle in Women with Menstrual Pain

Abstract

Objective. This study is performed to obtain objective diagnostic indicators associated with menstrual pain using pulse wave analysis. Methods. Using a pulse diagnostic device, we measured the pulse waves of 541 women aged between 19 and 30 years, placed in either an experimental group with menstrual pain (n = 329) or a control group with little or no menstrual pain (n = 212). Measurements were taken during both the menstrual and nonmenstrual periods, and comparative analysis was performed. Results. During the nonmenstrual period, the experimental group showed a significantly higher value in the left radial artery for the radial augmentation index (RAI) (p = 0.050) but significantly lower values for pulse wave energy (p = 0.021) and time to first peak from baseline (T1) (p = 0.035) in the right radial artery. During the menstrual period, the experimental group showed significantly lower values in the left radial artery for cardiac diastole and pulse wave area during diastole and significantly higher values for pulse wave area during systole, ratio of systolic phase to the full heartbeat, and systolic-diastolic ratio. Conclusion. We obtained indicators of menstrual pain in women during the menstrual period, including prolonged systolic and shortened diastolic phases, increases in pulse wave energy and area of representative pulse wave, and increased blood vessel resistance.

Acupuncture Differentially Affects the High-Frequency Spectral Energy in Radial Pulse Positions Depending on Type of Lower Back Pain

“…Each pulse profile provides information about the physiological conditions or disorders in the human body [5]. For example, Jeon et al studied pulse wave variation during the menstrual cycle and reported that the pulse appeared to be either string-like or slippery and rapid [6].…”

The Effect of Yoga Exercise on Menstrual Pain Reduction

“…In According to Cholifah (2015), yoga that is done regularly has an impact on increasing b-endorphins up to 5 times. The initial process of yoga is to focus on controlling the breath while inhaling, relaxing the muscles, causing pain, and diverting it to exhale slowly between the noses (Doina, 2013;Doulatabad, S., 2013;Aprilyadi, N., 2018;Jeon, SH., 2016). Feelings of comfort will activate the hypothalamus to release endorphins which have a natural sedative effect (natural painkillers), thereby spreading a sense of comfort (Nivethitha, 2016;Talib, 2019;Hapsari, 2020;Arini, D., 2020).…”

A Noncontact Method for Locating Radial Artery above Radial Styloid Process in Thermal Image

“…e analysis of the radial pulse waves is regarded as an important approach to evaluate patient status in traditional Chinese medicine (TCM) [1][2][3]. GUAN is a segment of the radial artery above the radial styloid process and a critical position for collecting pulse wave correctly in TCM diagnosis [4][5][6][7][8]. However, current methods for locating GUAN, including tactile sense and pressure sensor array, could not achieve precise positioning [5,6,[9][10][11][12][13].…”

“…GUAN is a segment of the radial artery above the radial styloid process and a critical position for collecting pulse wave correctly in TCM diagnosis [4][5][6][7][8]. However, current methods for locating GUAN, including tactile sense and pressure sensor array, could not achieve precise positioning [5,6,[9][10][11][12][13]. When sizes of those single sensors are almost less than 10 mm × 10 mm, it is difficult for people to place sensitive areas of a single sensor at the center of GUAN each time by tactile sense [4,7,[13][14][15].…”
