Official Title

Differences in Pelvic Floor Movement Levels Based on Population Characteristics and the Construction of an Assessment System

Brief Summary

The purpose of this study is to integrate millimeter-wave radar technology to investigate the dynamic movement characteristics of the pelvic floor muscles in patients with different Body Mass Index (BMI) and stress urinary incontinence. Based on this, a large database of pelvic floor movement parameters for Chinese women will be constructed, and a multi-subgroup standard atlas of pelvic floor muscle movement will be established to promote the standardized application of this technology in obstetrics and gynecology clinical assessments. This study also aims to explore the clinical value of pelvic floor movement assessment within the pelvic floor evaluation system, providing directions and insights for establishing a systematic evaluation system and standardizing the diagnosis and treatment of pelvic floor disorders.
