Objective of the study is to explore effect of combining transcutaneous tibial nerve stimulation with exercise on high post-void residual urine volume in post-menopausal women. The main question to be answered by this study:

Does transcutaneous tibial nerve stimulation technique combined with exercise have effect on high post-void residual urine in post-menopausal women? Researchers will compare 2 groups of 60 post-menopausal women. Group A participants will attend 12-week physiotherapy sessions composed of transcutaneous tibial nerve stimulation with exercise program and advice. While, control participants will take the same advice and routine care as group A participants.
