An apparatus for examining and curing urinary incontinence and exercising the pelvic floor muscles and vaginal muscles using bio-feedback including a controller main body, a probe, and a bio-feedback device. The probe includes: an insert frame extending in a longitudinal direction thereof an insert expansion part surrounding adjacent to a front end of the insert frame and expandable therearound an air supply path connected to the interior of the insert expansion part to supply air a handle engaged with the insert frame a fixing means for fixing the insert expansion part to the insert frame or the handle a valve installed at the air supply path and a PTC ceramic heater and a vibration motor installed at the insert frame. An elastic member includes a magnet, an insertion depth adjustment part, and leg support parts installed at the insertion depth adjustment part. The bio-feedback device includes a sound generating means, and an image display means. The main body includes a controller for controlling each component, a motorized air pump, an air flow detection sensor, a pressure detection sensor, a spring air cylinder, a solenoid air injection valve, an air tank, etc. Therefore, it is possible for a user to readily perform examination and treatment of urinary incontinence and pelvic floor muscle (vagina muscle) reinforcement exercise using bio-feedback.
