The invention provides a multifunctional rehabilitating treadmill. The multifunctional rehabilitating treadmill comprises a rehabilitating platform, and two supporting rods connected with the rehabilitating platform, wherein an operating platform is arranged at the tops of the two supporting rods; horizontal handrails are connected with the operating platform; vertical handrails are connected with the horizontal handrails in a bending manner; the bottom ends of the vertical handrails are fixed to the tail end of the rehabilitating platform; a protective belt is arranged on the horizontal handrails; the two ends of the protective belt are connected with the horizontal handrails on the two sides of the rehabilitating platform respectively; an elastic cushion is arranged at the front end of the rehabilitating platform; fixing components are arranged at the bottom of the front end of the rehabilitating platform; the upper ends of the fixing components are connected with the bottom ends of the supporting rods; the horizontal ends of the fixing components are connected with fixing rods; rubber sucking discs are arranged at the bottom ends of the fixing rods. According to data sent by a joint activity data acquisition module and a myoelectric data acquisition, a tablet computer judges the rehabilitation state of a current rehabilitee, and displays the rehabilitation states of joints and muscles on a touch screen, so that the rehabilitee can know the own body state more intuitively.
