Background Premenstrual syndrome (PMS) is a severe problem in women, and a well-balanced diet helps improve PMS symptoms. Eating disturbances are a major health problem in young women. Limited research has explored the correlation between eating behaviors and PMS symptoms in Japan. This study aimed to compare eating disturbances and the severity of...

Purpose Many women experience pain around the low back and pelvic girdle during/after pregnancy. These pains have different risk factors and require independent management strategies. Therefore, an epidemiological database is required to understand when each type of pain occurs, and how serious it could be. Thus, the history of pain in the lumbopel...

Childbirth support is important in Japan, where declining birthrates is one of the social issues. Delaying of progress of labor have been occur due to the lack of basic mother’s physical strength and is the risk of affecting the prognosis of the mother and fetal. In addition, there is a risk of urinary leakage and prolapse of the pelvic organs afte...

Delaying of progress of labor have been occur due to the lack of basic mother’s physical strength in Japan. The delay could be the risk of affecting the prognosis of the mother and fetal. In addition, that could cause urinary leakage and prolapse of the pelvic organs after childbirth due to the burden on the pelvic floor during childbirth. For smoo...

Perinatal well-being and support for childbirth are important issues as measures against the declining birthrate and women's social advancement in Japan.

If delivery progress is dela...

Specific physiological changes during pregnancy exert excessive strain on muscles such as the erector spinae (ES) and contribute to low back pain (LBP). The link between LBP and sit-to-stand (STS) motion has previously been investigated through motion analysis using an inertial measurement unit (IMU); however, the factors leading to LBP have not be...

Background The function of the pelvic bones is to transfer load generated by body weight. Proper function of the pelvic bones can be disturbed by alignment changes that occur during pregnancy. Further, misalignment of the pelvic bones can lead to pain, urinary incontinence, and other complications. An understanding of the timing and nature of pelvi...
