One-hour pad test.

• the test is started by putting one pre-weighted pad without patient voiding, -patient drinks 500 ml of sodium-free liquid in <15 min- then sits or rests,
• patient walks for 30 min, including climbing one flight of stairs (up and down),
• patient performs the following activities: standing up from sitting (10 ), coughing vigorously (10 ), running on the spot for 1 min, bending to pick up an object from the floor (5 ), and washing hands in running water for 1 min (this activity program may be modified according to the patient's physical fitness),
• the total amount of urine leaked is determined by weighing the pad. In the analysis of 1-hr pad test, an increase of 1-10 g is classified as representing mild incontinence, 11-50 g moderate and >50 g severe incontinence. The values for 24-hr pad test are classified as follows: Mild (4-20 g/ 24 hr), moderate (21-74 g/24 hr), and severe (>75 g/24 hr) incontinence
