An orthopedic device ankle exerciser for rehabilitating and exercising an injured ankle of a pair of feet where each foot has an arch, a heel, toes, and a mid portion and where one foot of the pair of feet has a healthy ankle. The orthopedic device ankle exerciser comprises a foot board, pivot means, and fastening means. The foot board has a central portion, a lower surface, an upper surface opposite the lower surface, a first end, and a second end opposite the first end. The pivot means pivotably and frictionally supports the foot board and the pivot means is fixably and centrally attached to the lower surface of the foot board at the central portion inorder to prevent horizontal translation of the foot board. The fastening means secures the pair of feet to the foot board in selectively fixed side-by-side relation and the fastening means is fixably attached to the upper surface of the foot board proximate the central portion. The fastening means is located and positioned for securing the pair of feet to the foot board so that the arch and the mid portion of each foot overly the pivot means and the central portion and this positioning provides maximum range of movement to the injured ankle. The heel is located in close proximity to the first end and the toes in parallel facing relationship to the second end. The fastening means co-acts with the foot board and therefore enables the healthy ankle to assist the injured ankle to move in upward and downward translation with the pivotal translation of the foot board and the heel of each foot maintains contact with the foot board so as to facilitate active and assisted dorsiflexion and plantar flexion of the injured ankle.
