The main purpose of this study is to reveal the effectiveness of the Knack maneuver and lifestyle recommendations program to be given in addition to the pelvic floor muscle training (PFMT) program, which has been proven to be effective in individuals with urinary incontinence symptoms after prostatectomy. This study is a prospective, controlled, randomized clinical trial. The study includes an 8-week pelvic floor muscle training, Knack maneuver and lifestyle recommendations.
In summary, it is stated in the literature that PFMT and lifestyle recommendations are beneficial in the treatment of urinary incontinence (UI). However, although there is evidence of the effectiveness of the Knack maneuver in stress UI in women, there is no evidence of the Knack maneuver in urinary incontinence after prostatectomy. On the other hand, the literature on the effect of lifestyle recommendations after prostatectomy is very limited.
Therefore, the aim of this study is to reveal the effectiveness of the Knack maneuver and lifestyle recommendations program, which will be given in addition to the PFMT program, which has been demonstrated in individuals with UI complaints after radical prostatectomy, in a randomized controlled design.

This study is a prospective, controlled, randomized clinical trial. The study includes an 8-week pelvic floor muscle training, Knack maneuver and lifestyle recommendations.
It was planned to enroll 72 individuals with urinary incontinence problems after radical prostatectomy in this randomized controlled clinical study. A physical therapist is responsible for all assessments.
Participants were included in one of three treatment groups (G1: Pelvic floor muscle training + Knack maneuver + lifestyle recommendations; G2: Pelvic floor muscle training + Knack maneuver G3: Pelvic floor muscle training).

With this study, the effectiveness of different programs to be applied to individuals suffering from urinary incontinence after prostatectomy will be determined and compared. It will increase the level of evidence for the treatment of urinary incontinence, a common complaint after prostate cancer surgery. In this direction, it will also contribute to the development of public health.
