We aimed to correlate pressure\u2010flow urodynamic parameters with video\u2010gait analysis parameters in PD. We recruited 41 patients with PD (25 men and 16 women; age, 70.6 \u00b1 8.5 years; H &amp; Y motor grading: 2 [range, 1\u20133]; disease duration: 4 years [range, 1\u20137]; taking levodopa 300 mg\/day [range, 100\u2013400]). All patients underwent pressure\u2010flow urodynamics (parameters: first sensation, bladder capacity, detrusor overactivity [noted in 24 patients], and Watts factor [WF]) and video\u2010gait analysis (parameters: time and number of strides for 5\u2010m gait [simple task] and time for timed up and go [complex task]). Statistical analysis was made by Mann\u2010Whitney's U\u2010test for analyzing the relation between detrusor overactivity and gait as well as Spearman's rank\u2010correlation coefficient test for analyzing the relation between the remaining parameters and gait. We found no relation between filling\u2010phase urodynamics (detrusor overactivity, first sensation, and bladder capacity) and video\u2010gait analysis parameters. By contrast, we found a significant relation between voiding\u2010phase urodynamics (WF, reflecting detrusor power) and all three video\u2010gait analysis parameters (reflecting lower\u2010half bradykinesia and loss of postural reflex) in our PD patients (<jats:italic>P<\/jats:italic> &lt; 0.01). The close relation between the WF and motor disorders in the present study suggests that, though clinically mild, a weak detrusor in PD might have a central origin. We should follow postvoid residual volume carefully in PD patients with advanced gait disorder, because postvoid residual volume might increase in such patients. \u00a9 2012 Movement Disorder
