Efficacy of biofeedback in the treatment of urinary stress incontinence.

Thirty-seven women with stress incontinence were given biofeedback instruction on how to perform pelvic floor exercises correctly. After 3 months with home exercises 31 patients performed a new standardized pad-weighing test: 39% were objectively cured and 42% improved. After a mean of 2 years 15 patients were evaluated with another pad-weighing test: 27% were now objectively cured and 47% improved. A questionnaire showed that 78% had an exact knowledge about the location of the pelvic floor muscles and 47% were satisfied with their present situation, but only 58% performed daily exercises.
