A wearable hand rehabilitation system includes: a base, multiple actuating units configured to the base, hand assistive unit and multiple sheaths connected with the actuating units and the hand assistive unit. The base is composed of a cover and a base plate to create a space. A hole closed to the middle of the cover to make every sheath to cross the cover. As a result, the sheath could connect with actuating units. When a user put on the wearable hand rehabilitation system, the user could move or rotate the users arm to make users five fingers to grab something. The usage of the wearable hand rehabilitation system could evaluate the hand rehabilitation condition of the user.
