A bilateral hand rehabilitation device is disclosed. The device includes a pair of left and right handlebar members that are fixedly coupled or connected together. The device further includes a pair of moveable left and right finger grip members, one for each of the handlebar members. Each finger grip member being elongate and having a longitudinal axis that is substantially parallel to the longitudinal axis of its respective handlebar member, and each finger grip member being moveably mounted with respect to its respective handlebar member for movement toward and away from the handlebar member to facilitate a user finger grasp and release movement when in use. The device further includes an asymmetric connection mechanism that operatively couples the pair of finger grip members to each other for simultaneous asymmetric movement of the finger grip members such that the movement of one finger grip member toward or away from its respective handlebar member causes the other finger grip member to move in the opposite direction away or toward its respective handlebar member.
