Urodynamic Effect of Transcutaneous Electrical Posterior Tibial Nerve Stimulation in Overactive Bladder after Partial Spinal Cord Injury

Background: Overactive Bladder Syndrome (OAB) refers to individuals with the following symptoms: urinary urgency, excessive urinary frequency, or urge incontinence.These symptoms usually occur after partial spinal cord injury.Objective: to investigate the urodynamic effect of transcutaneous posterior tibial nerve stimulation in overactive bladder after partial spinal cord injury.Subjects: thirty subjects were divided into 2 groups: -Group (A): fifteen patients with overactive bladder after partial spinal cord injury above T12 (treated by transcutaneous posterior nerve stimulation and pelvic floor muscle exercises).Group (B): fifteen patients with overactive bladder after partial spinal cord injury above T12 (treated by pelvic floor muscle exercises) Methods: All subjects were submitted to complete clinical evaluation and assessed using urodynamic test and revised urinary incontinence scale (RUIS).Results: By comparison between both groups, the group which was treated by electrical stimulation and pelvic floor muscle exercise (group A) show increase in urodynamics parameters as bladder maximum cytometric capacity, bladder stability, maximum flow rate more than ( group B) which was treated by pelvic floor muscle exercises only.Conclusion: Transcutaneous posterior tibial nerve stimulation has good urodynamic effect on overactive bladder in patients after partial spinal cord injury.
