Arm && Interventions

Group	Intervention	Description
Bilateral Posterior Tibial Nerve Stimulation	Transcutaneous Electrical Nerve Stimulation	Transcutaneous posterior tibial nerve stimulation applied 40 minutes every day for a duration of 4 weeks. The patient places the cathode electrode above, and the anode electrode behind, the medial malleolus, over the posterior tibial nerve on both legs and sets the stimulation intensity to a comfortable level.
Unilateral Posterior Tibial Nerve Stimulation	Transcutaneous Electrical Nerve Stimulation	Transcutaneous posterior tibial nerve stimulation applied 40 minutes every day for a duration of 4 weeks. The patient places the cathode electrode above, and the anode electrode behind, the medial malleolus, over the posterior tibial nerve and sets the stimulation intensity to a comfortable level.
Shoulder stimulation	Transcutaneous Electrical Nerve Stimulation	Stimulation applied 40 minutes every day for a duration of 4 weeks. The patient places the cathode and the anode electrodes on the lateral side of the left shoulder.

Primary Outcome Measures

Name	Time	Method
Change in Patient Perception of Bladder Condition (PPBC)	baseline, 4 weeks	Change in the patient's bladder condition based on the PPBC questionaire from baseline to after 4 weeks of the treatment.
Change in frequency of voiding	baseline, 4 weeks	The change of urinary frequency from baseline to after 4 weeks of the treatment, measured by a 3 days bladder diary.

Secondary Outcome Measures

Name	Time	Method
Change in urinary symptoms score and bother symptom score based on the ICIQ-OAB questionnaire	baseline, 4 weeks	Change in urinary symptoms score and bother symptom score based on the ICIQ-OAB questionnaire from baseline to after 4 weeks of the treatment
Changes in symptom severity score and health-related quality of life score (HRQL) based on OAB-questionnaire	baseline, 4 weeks	Change in symptom severity score and HRQL score from baseline to after 4weeks of the treatment.
Changes in the mental/physical scores of RAND36	baseline, 4 weeks
