A spine regularity rotation motion device includes a T-shaped hanger, a neck traction belt, an n-shaped base, and a horizontal rotary drive platform, wherein the T-shaped hanger is connected to the neck traction belt via a pulling belt at one end, and is connected to the n-shaped base through a main elevating post at another end. A user can rest his face on the neck traction belt, which is gently pulled upwards to increase the space between the cervical joints and align the spine to the center. The horizontal rotary drive platform is provided inside the n-shaped base with a correction seat on the top for the user to sit on. The seat allows the hip of the user to move in a regularity rotation manner that is opposite to the directions of the twisted and/or bent lumbar spine or skewed pelvis. An underarm support is also provided to raise the spine and reduce stacking to facilitate the rehabilitation process.
