Non-invasive biofeedback-assisted vs. conventional pelvic floor muscle training combined with high-effort resistance training for urinary incontinence after radical prostatectomy: a randomized controlled trial.
Both device-based and physiotherapist-guided pelvic floor muscle training combined with high-effort resistance training were associated with significant reductions in objectively measured urinary leakage after radical prostatectomy, with no statistically significant between-group differences observed.
Key Findings
Results
All participants demonstrated a statistically significant reduction in 24-hour pad test values from baseline to the end of the 12-week program.
Mean reduction in cumulative pad weight was -86.39 g (SD: 336.25 g) across all participants
Reduction was statistically significant at p < 0.001
96 out of 109 participants (88%) completed the intervention
Urinary leakage was assessed using the 24-hour pad weight test at baseline (T0) and after 12 weeks (T1)
Results
Treatment success (≥50% reduction in urinary leakage) did not differ significantly between the device-based PFMT group and the physiotherapist-guided PFMT group.
Treatment success was the primary endpoint, defined as ≥50% reduction in urinary leakage
OR = 1.19, 95% CI 0.53–2.66; p = 0.670
Treatment success was achieved by 52.1% of all participants overall
dPFMT group: n = 55; pPFMT group: n = 54
Results
In a post hoc exploratory analysis restricted to participants achieving treatment success, the relative reduction in urinary leakage was greater in the device-based PFMT group than in the physiotherapist-guided PFMT group.
Mean relative reduction in dPFMT group: -83.97% (SD 13.88%) vs. -74.68% (SD 12.93%) in pPFMT group
Difference was statistically significant at p = 0.017
Authors caution that this is an exploratory post hoc finding and no adjustment for multiple testing was applied
Authors state 'this exploratory finding should be interpreted with caution'
Results
Time since surgery was a significant negative predictor of treatment success, while age and follow-up rehabilitation treatment were not.
Time since surgery predicted treatment success at p < 0.001, with a negative association (longer time since surgery associated with lower likelihood of treatment success)
Age was not a significant predictor (p = 0.313)
Follow-up rehabilitation treatment (AHB) was not a significant predictor (p = 0.994)
None of the examined variables predicted the magnitude of change in urinary leakage
Methods
Both intervention groups underwent a 12-week whole-body high-effort resistance training program performed at moderate to high loads in addition to their respective PFMT interventions.
Resistance training was performed at greater than 60% of 1-repetition maximum
Training was performed to momentary failure
dPFMT group used a non-invasive biofeedback-assisted device for pelvic floor muscle training
pPFMT group received conventional physiotherapeutic pelvic floor muscle training
What This Means
This research suggests that men who experience urinary leakage after prostate removal surgery (radical prostatectomy) can benefit significantly from pelvic floor muscle training combined with high-intensity strength exercise. The study compared two approaches over 12 weeks: one using a non-invasive biofeedback device to guide pelvic floor exercises, and one using conventional physiotherapist-led pelvic floor training. Both groups also performed whole-body resistance (strength) training at moderate to high effort levels. About 88% of participants completed the program, and on average, all participants showed a meaningful reduction in urine leakage as measured by pad weight tests.
The study found that roughly half of all participants (52.1%) achieved 'treatment success,' defined as at least a 50% reduction in urinary leakage, and this rate was similar between the two training approaches. In an exploratory analysis looking only at those who did achieve treatment success, the biofeedback device group showed a somewhat larger percentage reduction in leakage compared to the physiotherapist-guided group, but the authors caution that this finding should be interpreted carefully because it was not the primary analysis and was not statistically adjusted for multiple comparisons. Importantly, the sooner after surgery a man began the program, the more likely he was to achieve treatment success.
This research suggests that both home device-based and clinician-guided pelvic floor training, when combined with structured strength training, may help reduce urinary leakage following prostate surgery. The finding that time since surgery matters highlights the potential importance of starting rehabilitation promptly after the operation. Neither patient age nor whether someone had received prior follow-up rehabilitation affected the likelihood of success.
