URIDOC™/PANDOC™ sends various patterns of electric pulses to your muscles through four electrodes located in front of the device. Muscles respond to the pulses by contracting and relaxing rhythmically. Contraction and relaxation of the muscles result in soothing massage sensations similar to those given by a massage specialist. Soft vibration is added to ease the feeling of the pulses. The motion of URIDOC™/PANDOC™ works on the muscles surrounding the bladder, stimulates it and helps emptying it.
