 Overactive bladder (OAB) is a common problem, affecting about 1 of every 6 adults in the United States.   Drug therapies are the first line treatment for OAB.  However, more than 70% of patients stop taking drugs due to low efficacy and side effects.  Current alternative treatments include sacral and tibial neuromodulation, and bladder botox injections.  These are invasive, expensive, inconvenient, and carry significant risks. FootStim TM  is a novel, non-invasive foot neuromodulation therapy for OAB. It can decrease bladder activity through treatment performed at home safely, comfortably, and conveniently, with no adverse side effects. It uses a small wearable stimulator to activate the nerves on the foot via skin surface electrodes that then alter nerve signals to the bladder.  Studies in animals and humans have already shown that foot stimulation successfully inhibits bladder activity and increases urine storage volumes.
