Abstract: A therapeutic table for manipulation of the spine and pelvis of a patient supported thereon. The table includes a tiltable frame mounted to a base, and a torso support member carried by the frame. A drive shaft carried by the frame is connected by a hinge to a driven shaft extending rearwardly of the torso support member. The driven shaft in turn carries a pelvic/lumbar spine support member on which a patient may kneel. When the hinge connecting the two shaft portions is adjusted to a non-zero angle, rotation of the shaft induces a circumductive motion in the pelvic/lumbar spine support member, the degree of such motion being dependent on the angle of the hinge.
