A comparison of a step-initiation task in women with and without urinary incontinence. A case-control study.

Aims: The aim of the study was to objectively determine differences in postural response by women with and without urinary incontinence during a step-initiation task depending on the degree of bladder filling.

Methods: The study comprised 22 women with stress urinary incontinence and 20 women without urinary incontinence. All women participated in four trials: unperturbed and perturbed (obstacle crossing) transition between platforms, step-up and step-down trials.
