The pelvic floor muscle activity is then transmitted to the Smartphone app, and the biofeedback is displayed in real time. Within the smartphone app are a series of pre-programmed exercises that address the development of strength, endurance, and tone. These programs are aimed at taking the guesswork out of incontinence biofeedback exercises. They increase in intensity as a woman progresses, offering a variety of work and rest periods to help patients build endurance and strength. The Quick Flex program is designed to assist with reaction time, guiding patients in quickly contracting and releasing the pelvic floor muscles.
