Study aim: To investigate the effect of acupuncture with electrical stimulation (EA) compared with electrical stimulation of the posterior tibial nerve (PTNS) in urinary disorders in patients with multiple sclerosis Design: Phase 3 randomized, parallel-group clinical trial (using a random number table) on 38 patients Settings and conduct: protocol for the first group: 12 sessions Electrical stimulation of the posterior tibial nerve by placing a surface electrode behind the medial malleolus and a needle electrode 5 cm cephalad and 1.5 cm behind the medial malleolus with a stimulation frequency of 20 Hz, a pulse width of 200 milliseconds, a voltage of 9 mV, /protocol for the second group: 12 sessions stimulation at specific points related to urinary incontinence with a frequency of 20 Hz Participants/Inclusion and exclusion criteria: Inclusion: Individuals 18 years of age or older / diagnosed with MS by a neurologist who are stable in terms of disease progression (operationally without change in physical or mental symptoms in the past 4 months) / have an EDSS score of less than 6.5 / have sufficient cognitive capacity to complete the evaluation and treatment protocol Exclusion: Pregnancy, previous gynecological, urological and/or neurosurgery, cesarean section or vaginal delivery in the past 6 months, pelvic organ prolapse greater than stage I / have a urinary tract infection / increase in EDSS score of more than 0.5 from baseline Intervention groups: The first intervention group examined the effect of electroacupuncture/the second intervention group examined the effect of PTNS. Main outcome variables: Age/Gender/Urinary Symptoms/Quality of Life/Intervention/Level of Physical Health/Level of Mental Health
