QUESTION: What is the effect of an expanded warm-up program including pelvic floor muscle training (PFMT) compared with usual warm-up on bother and prevalence of urinary incontinence (UI) among rhythmic gymnasts? What is the self-perceived effect of PFMT, including its progression over time, assessed via the global rating of change?
DESIGN: A cluster-randomised controlled trial with concealed allocation and intention-to-treat analysis.
PARTICIPANTS: Gymnasts had to be ≥ 12 years of age and training in rhythmic gymnastics ≥ 3 days/week. Twenty-three rhythmic gymnastics clubs were randomised to an experimental group (12 clubs, 119 gymnasts) or a control group (11 clubs, 86 gymnasts).
INTERVENTION: The experimental group performed one set of 8 to 12 near-maximum pelvic floor muscle contractions and exercises for the knees, lower back and hip/groin as warm-up before each training session for 8 months. The control group continued rhythmic gymnastics training as usual without PFMT or additional lower back and lower limb exercises.
OUTCOME MEASURES: Primary outcomes were bother from UI (score 0 to 21) and prevalence of UI, each measured by the International Consultation on Incontinence Questionnaire - Urinary Incontinence Short Form (ICIQ-UI-SF). The secondary outcome measure was the self-perceived effect and its progress over time, assessed using the global rating of change (-5 to 5).
RESULTS: The difference between the groups in the ICIQ-UI-SF total score (ie, UI bother) was clearly negligible (MD -0.48, 95% CI -1.27 to 0.31). The prevalence of UI reduced from 46 to 41% in the experimental group and increased from 32 to 34% in the control group; despite this, the risk difference at 8 months was negligible (RD 0.07) and the confidence interval spanned mainly negligible effects (95% CI -0.08 to 0.21). Experimental group participants rated their global change at a mean of 2.1 (SD 1.7).
CONCLUSION: Eight months of warm-up before rhythmic gymnastics training sessions that included one set of 8 to 12 near-maximum PFM contractions did not reduce UI bother. The effect on UI prevalence was also likely to be negligible, despite experimental group participants perceiving benefit from the intervention.
