Abstract: The present invention relates to a pillow apparatus for inducing cervical vertebral extension exercise and a long-term rehabilitation treatment for patients with ruptured cervical disk through changes in the height of a head support by adjusting the length of a shape memory alloy wire, comprising: a power unit for fixing the shape memory alloy wire and simultaneously providing power to a horizontal rack through changes in length; a rotation unit including the horizontal rack converting tension generated by the length change of the wire into a rectilinear motion, a first gear converting the movement of the horizontal rack into a rotary motion, a shaft transmitting the rotary motion of the first gear to a second gear and a third gear, the second gear, and the third gear; and a driving unit including of a first vertical rack converting the rotary motion of the second gear into a rectilinear motion, a second vertical rack converting the rotary motion of the third gear into a rectilinear motion, and a head plate fixing onto the first vertical rack and the second vertical rack. The pillow apparatus of the present invention can induce cervical vertebral extension exercise which a user wants through a method for controlling current flow, thereby continuously and regularly giving physical stimuli, helpful to the rehabilitation treatment. Additionally, the apparatus does not generate noise and vibration, generated in a driving method using the existing motors, thereby enabling a user to receive physical therapy more comfortably.
