Timed voiding programs involve establishing a schedule for urination. To do this, a person fills in a chart of voiding and leaking. From the patterns that appear in the chart, the person can plan to empty his or her bladder before he or she would otherwise leak. Some individuals find it helpful to use a vibrating reminder watch to help them remember to use the bathroom. Vibrating watches can be set to go off at certain intervals or at specific times throughout the day, depending on the watch. Through this bladder training exercise, the person can alter their bladder's schedule for storing and emptying urine.
