Objective: to investigate the response of the pelvic floor muscles (PFM), and urinary incontinence (UI), in patients having undergone a prostatectomy, after treatment using electrical stimulation. Materials and methods: this observational study was conducted in an outpatient urogynecologic physical therapy clinic of Hospital dos Servidores in Rio de Janeiro, Brazil from August to September 2012. Ten patients (aged, 64 ± 7 years) with urinary incontinence resulting from radical prostatectomy, having received surgery within six months of study entry, without urinary infection, and without metallic implants underwent electrical stimulation of the PFM, while in lateral decubitus position with knees and hips flexed. The parameters used were 65 Hz frequency, pulse width of 500 µs, biphasic current, intensity according to the tolerance level reported by the patient, perineal contraction time of four seconds, and rest time of eight seconds for 20 minutes twice a week, totaling 16 sessions of electrical stimulation with active-assisted contraction. Patients were evaluated before and after electrical stimulation through physical therapy evaluation of urinary incontinence, by being asked about the number of disposable guards used daily, using a visual analogue scale (VAS) to measure how the UI interfered with activities of daily living, and by electromyographic biofeedback to measure the work of the PFM. Data were analyzed using Student’s paired t-tests and a significance level of 0.05. Results: after 16 sessions of electrical stimulation, the electromyographic biofeedback evaluation showed a significant increase in muscle strength of 10.73 ± 8.64 to 17.16 ± 9.00 µV (t = -3.39, P = 0.008), a significant decrease in the number of diapers used before and after treatment (3.9 ± 1.2 to 1.8 ± 1.5, respectively; t = 5.16, P = 0.0006), and a significant decrease in the interference of urinary incontinence on daily activities of 9.6 ± 0.5 to 4.0 ± 3.8 (t = 5.15, P = 0.0006). Conclusion: electrical stimulation may represent a novel way to strengthen the pelvic floor muscles and decrease urinary incontinence resulting from radical prostatectomy.Downloads
