SUBSTANCE: feedback vaginal expander is applied for training of the vaginal and anal sphincter muscles. The trainer represents two extended elements one-end pivotally connected to form a protuberant head to be inserted in the vagina or anus. A spring of a various resistance spring set is provided between these extended elements. The other two ends of the extended elements are free and separated by the spring pressure. Version 1. One of the extended elements has a number of magnetically operated sealed switches, while on the other one, there is a magnet. The relative position of the magnetically operated sealed switches and magnet is specified so that a magnetically operated sealed switch mostly spaced from the magnet is found in the magnetic field of the magnet when closing the trainer completely. The magnetically operated sealed switches are put into circuit including a power supply and light indicators. An audio indicator or a vibromotor are connected to the circuit as optional detection devices. The audio or vibroindicator actuation is preset for one of the magnetically operated sealed switches by means of buttons or a panel switch. Version 2 differs by the fact that one of the extended elements comprises a magnetically operated sealed switch (5), while the other one has a magnet (6).
