In their highly innovative article, Hentzen et al. [1] introduce and validate a specific test to measure the global time required for people with multiple sclerosis to reach the bathroom and prepare for micturition. As the authors acknowledge, urge urinary incontinence is pervasive among people with multiple sclerosis, and urinary dysfunction has been widely implicated in diminished quality of life in this population [2]. Consistent with prior research of otherwise healthy community-dwelling older women, urge urinary incontinence has been associated with impaired mobility [3]-a hallmark of multiple sclerosis [4]. However, the breadth of neurologic symptoms which may accompany a diagnosis of multiple sclerosis extends far beyond gait disturbances [4], and potential deficits in cognition, vision, limb coordination, strength, and muscle tone are all highly relevant to the extra-ambulatory tasks required for a successful trip to the bathroom. Accordingly, we agree that the Time to be Ready to Void test reflects a far more relevant means by which clinicians may quantify real-world functional impairment in the processes related to toileting.
