A multifunctional rehabilitation device comprises a base body formed with a bottom surface and a top surface and a massaging member formed with a bottom portion opened with a sliding groove. A first massaging section is protrudingly arranged on a first end of the base body on the top surface thereof, an ankle-shaped abutment section is concavely arranged nearby an inner side of the first massaging section, and a long-strip sliding board formed on another end of the base body is opened with an adjusting groove. The massaging member can be sleevingly arranged on the sliding board of the base body by sliding on the sliding groove of the massaging member. In addition, the massaging member is protrudingly arranged with a second massaging section and a third massaging section that are directionally identical to the first massaging section of the base body and parallel to each other. Accordingly, multifunctional rehabilitation effects of conducting foot sole stretching, human body skin scraping, buttock and spine pressing can be attained, and defects of being unable to achieve applications of pressing and force can be effectively overcome, thereby improving practicability.
