Aims Radical prostatectomy may cause stress urinary incontinence (SUI). We compared continent and incontinent men after radical prostatectomy, in regard to the change of the temporal pattern of pelvic floor activation during cough. Methods Twenty‐two patients were included in this prospective, multicentric study. All patients gave their informed consent. Simultaneous recordings of electromyographic activity of external anal sphincter (EAS EMG) and external intercostal muscle (EIC EMG) during cough were performed with a pair of pregelled surface electrodes. Cough effort caused an involuntary pelvic contraction. Intercostal muscles recording was chosen because they are one of the muscular components of cough initiation with diaphragm muscle. Twenty‐four‐hour pad‐weighing test was used to quantify urinary incontinence. The primary endpoint was the latency between the onset of EIC EMG and EAS EMG (RT3), during a cough effort. We also measured the contraction time, the maximum EAS EMG activity, and the area under the curve. Results All the patients were analyzed: 12 continent and 10 with SUI. The median age was 66 years old. Both groups were similar except in term of follow‐up. Median latency was increased by −1.7 ms (−47.9; +34.2) to 55.8 ms (+47.5; +80) in patients with SUI (P = 0.0033; Table 2). The duration of the contraction, the maximum EAS EMG activity and the area under the curve were not different. Conclusions The latency between the onset of EIC EMG and EAS EMG is increased in patients with SUI after radical prostatectomy. It may be one of the reasons for SUI in these patients.

“…Considering an expected difference of 30% between the two groups regarding the latency between the onset of the involuntary EAS EMG activation and the onset of the EIC EMG activation (RT3) after rehabilitation (meaning that we expected a 30% faster perineal pre‐contraction in response to cough effort in women who underwent double task rehabilitation, compared with the control group), and a power of 95% and an α ‐risk of 0.05, 13 volunteers were included in each group. Thirty percent was chosen because in the case of a DT, we previously showed that latency of the perineal pre‐contraction was 30% shorter . To improve the power of our study, two controls were included for each patient included in the rehabilitation group.…”

“…In continent women, we previously observed that a mental DT altered reaction time (RT) between an order to contract PFM and the onset of PFM contraction activation . In the same way, during a mental DT, the RT between the initiation of cough effort (activation of the external intercostal muscles) and the onset of the PFM contraction is delayed . In the same way, during a mental DT, the RT between the initiation of cough effort (activation of the EIC muscles) and the onset of the PFM contraction is delayed .…”

In the same way, during a mental DT, the RT between the initiation of cough effort (activation of the EIC muscles) and the onset of the PFM contraction is delayed . This kind of experiment, which consisted in performing two activities simultaneously (eg, a mental task and a motor task or two motor tasks), is currently called a “dual task.” The first dual task rehabilitation model was described by Elliott et al, who explored a dual task paradigm including two motor tasks: a dance game program combined with a voluntary PFM contraction to treat 24 women suffering from mixed urinary incontinence.…”
