Research Abstract

This study aims to develop of the prevention and improvement program for stress urinary incontinence by clarifying the relationship between inner muscular strength and the urinary incontinence symptoms during pregnancy and childbirth. Ultrasonography was used to evaluate of muscle function in this study, then we revealed that stress urinary incontinence after childbirth was influenced by the diminishing function of the pelvic floor muscles. The display feedback of pelvic floor muscle contraction using ultrasonography was conducted as part of the motor learning program. As a result, the symptoms of urinary incontinence and general excretion due to decreased function of pelvic floor muscles were improved. However, there were some women with inadequate motor learning of muscle contraction. Thus, further analysis of the results and examination on how to provide the program are necessary.
