Study aim: The effect of dynamic neuromuscular stabilization exercises on urinary incontinence in patients with multiple sclerosis Design: In this study, due to the small number of samples, in consultation with a statistician, it was decided to use the random blocking method. Blocking is usually used to balance the number of samples assigned to each of the groups studied. The statistician used the website https://www.sealedenvelope.com/simple-randomiser/v1/lists, considering that we had 2 groups, to design a suitable blocking table. Divides patients according to this table is unaware of the study. Settings and conduct: The place of this study is Isfahan, Ayatollah Kashani St., Kashani Hospital, physiotherapy ward and the time of its conduct is 2021.Study begins with obtaining permission from the ethics committee. Volunteers attend the physiotherapy department of Kashani Hospital. All stages of the work and the purpose of the research for patients are described in detail and the consent form is completed by them. In this study, patients are unaware of the groups. In both experimental and control groups, exercise therapy is performed, but the exercises are different.Also, the person doing the assessments is unaware of the groups.

Inclusion criteria include having a low disability to participate in the study and having at least one urinary incontinence in the past month. Exclusion from the study is other neurological diseases. Intervention groups: In this study, the control group of Kegel exercises and the experimental group of dynamic neuromuscular stabilization receive.
