Abstract
Stress urinary incontinence is common in men after prostate cancer surgery. Rehabilitative interventions incorporate pelvic floor muscle training, biofeedback, electrical stimulation, lifestyle changes, or a combination of these strategies. However, little is known about the physiological impact of whole-body vibration for stress urinary incontinence after radical prostatectomy.
To investigate the effect of whole-body vibration training on stress urinary incontinence after prostate cancer surgery.
Randomised controlled trial.
Tertiary university hospitals.
Sixty-one patients with mild stress urinary incontinence after radical prostatectomy.
Group 1 included 30 patients who performed pelvic floor muscle training and whole-body vibration training with a frequency and amplitude of 20Hz/2mm for the first two sessions and 40Hz/4mm for the rest of the intervention. Group 2 included 31 patients who performed pelvic floor muscle training alone. The intervention in both groups was conducted three times per week for 4 weeks.
Incontinence Visual Analogue Scale (I-VAS) score, International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI-SF) score and 24-hour pad test result.
I-VAS score, ICIQ-UI-SF score and 24-hour pad test result showed significant within-group differences at each assessment with the exception of the baseline and post-intervention I-VAS score in Group 2. For example, Group 1 I-VAS score had a median difference of 3.9cm [95% confidence interval (CI) −4.0 to −3.8] from baseline to first follow-up, and a median difference of −2.0cm (95% CI −2.2 to −1.8) at 4-week follow-up. Comparisons between the groups demonstrated significant differences in favour of Group 1 after 4 weeks of intervention and at follow-up for all measured parameters.
Whole-body vibration training is an effective modality for treating patients with stress urinary incontinence after prostatectomy.
