TENS that was applied once daily, three times per week for 8 weeks. Each treatment session was conducted for 20 minutes, two electrodes were positioned over the perineal area between anus and scrotum on the Centrum tendineum, while the other two electrodes were applied under the buttocks medially at the level of the ischial spines (medial to the ischial spines bilaterally) with the patient in comfortable supine hook-lying position with abducted hips. to prevent burn beneath the electrodes, the surface area of the electrode should be equal to or greater than 4 cm2 to minimize the heat production. In addition, to decrease the current density between electrodes, the inter-electrode distance was less than the cross sectional area of the electrode
