A medical therapy arrangement, for applying electrical stimulation to a subject, includes a garment having electrodes at an inner surface. A control unit controls each electrode to work as one or more of anode, cathode or disconnected state, per a predetermined therapy stimulation program. Furthermore, the arrangement includes: at least one connection unit having a predetermined number of connection elements respectively electrically connected to the electrodes via separate connection lines being flexible and elastic and integrated into the garment; at least one connection board having a predetermined number of connection pads electrically connected to the control unit. The connection unit is an integrated part of the garment, with the connection board detachably attachable to the connection unit by a fastening element, such that the connection unit and the connection board, when interconnected, are positioned relative to each other in order to electrically connect the connection pads to mating connection elements.
