Résumé
Aims The fall rate in urgency urinary incontinence (UUI) and mixed UI (MUI) older women is higher when compared with that of continent women. One hypothesis is that a strong desire to void (SDV) could alter gait parameters and therefore increase the risk of falls. The aim of this study was to investigate and compare the effect of SDV on gait parameters in UUI/MUI and continent older women who experienced falls. The secondary aim was to determine the relationship between UI severity and gait parameters in incontinent women. Methods A quasi-experimental pilot study was conducted with two groups of healthy community-dwelling women who experienced at least one fall in the last year: continent (n = 17; age: 74.1 ± 4.3) and UUI/MUI (n = 15; age: 73.5 ± 5.9). We recorded, analyzed, and compared spatiotemporal gait parameters for participants in each group with both SDV and no desire to void condition. Results A pattern of reduced velocity (P = 0.05) and stride width (P = 0.02) was observed in both groups with SDV. Incontinence severity was correlated with reduced velocity (rs = −0.63, P = 0.01), increased stance time (rs= 0.65, P = .01) and stance time variability (rs = 0.65, P = .01) in no desire to void condition and with reduced velocity (rs = −0.56, P = .03) and increased stride length variability (rs = 0.54, P = .04) in SDV condition. Conclusions SDV reduced gait velocity and stride width regardless of continence status in older women at risk of falls. Further, UI severity in the UUI/MUI women was correlated to reduced gait velocity and increased variability. Our findings could explain the higher fall rate in this population.
