one of the major annoying disorders occurring in people with multiple sclerosis is lower urinary tract disorders (LUT). Urgency is considered the main one seriously influencing the quality of life. Neurogenic detrusor over activity (DOAB) is characterized by a hyperreflexic, overactive detrusor that responds quickly to low-intensity sensory input from general visceral afferent fibers. Overactivity has been claimed to induce random, uncontrolled contractions of the detrusor muscle, leading to intravesicular pressure rise, producing urgency, frequency, and consequently incontinence AIM: To demonstrate the therapeutic efficacy for posterior tibial nerve stimulation (PTNS) in neurogenic over active bladder (NOAB) in people with multiple sclerosis METHODS: The current trial is a prospective, randomized controlled study. Forty remitting relapsing males with MS with moderate NOAB symptoms were randomly assigned into two equal groups; control group (C) treated by selected therapeutic exercises program for strengthening pelvic floor muscles and an intervention group (ES) receiving an additional posterior tibial nerve electrical stimulation. Each session ranged from 45- 50 minutes, three days weekly for a month. Outcome measures were recorded before starting the treatment and after termination of the study intervention and included over active bladder symptoms score (OVBS) score, urodynamic parameters (uroflow, filling and voiding cystometry), and post voiding residual volume by abdominal ultrasound RESULTS: There was a significant improvement of all voiding parameters compared to baseline and the group C except frequency of urgency incontinence. A significant decrease was detected in post-treatment mean episodes number of nighttime frequency, urgency, urgency incontinence (1.65 ± 0.93, 1.2 ± 0.52 and 1.5 ± 0.76) respectively of the ES group compared to that of group C (3.05 ± 1.09, 2.25 ± 0.71 and 2.25 ± 1.06) (P < 0.01). There was a significant decrease in median post-treatment OVBS score 3 (3-3) compared to group C median score 5 (6-4). A statistically significant improvement was observed of all urodynamic parameters (bladder capacity and compliance, Detrusor overactivity (DO), maximum flow rate and post voidal residual volume in the ES group compared to the group C CONCLUSION: PTNS is a promising and potentially beneficial treatment option for NOAB symptoms in males with MS and superior to pelvic floor muscle training alone.
