A Windows-DOS based biofeedback game system is currently used at the investigator's institution to help treat LUTD in pediatric patients. This system, however, is outdated and needs to be replaced with updated hardware and software. A new updated system was recently created by University of Wisconsin-Madison (UW) Biomedical Engineering students. This system utilizes a FDA approved EMG device (SRS Medical Aware™ EMG Dual Muscle Monitor) paired with biofeedback game software that was developed by the students. The investigators wish to test the usability of the new software to identify areas that need improvement to make the software more user-friendly.
