Abstract: An advanced physiotherapy walking assistant on wheels, reconfigurable for multiple medical rehabilitation and physiotherapy purposes to provide the user with adequate body support in an upright position, and optimal bipedal mobility. The walking assist device is equipped with calibrated helical springs, placed between an adjusting unit for vertical movement screw and the portal frames, thus providing a floating body support instead of a rigid support, in order to thus enable the accompaniment of the vertical thoracic movement resulting from walking, and a readjustment of the level of body support of the patient. The walking assist device comprises a base frame on four castor wheels, an articulatable upper rail frame assembly positioned by means of removable support tubes, assembly or portal frame for pelvic support, an assembly or portal frame for underarm support, and calibrated helical springs supported by two track portals.
