An apparatus for manipulating a user's back while supporting the user's back and hips includes a support defining a longitudinal axis, and a seat pad disposed along the support at a position corresponding to the user's hips for supporting the user's hips. The seat pad is rotatable around the longitudinal axis and has an attached seat belt for holding a user on the seat pad. A pair of handles are provided, one on each side of the seat pad, which are coupled to the seat pad and which are movable in reciprocal back-and-forth motion to control rotation of the seat pad around the longitudinal axis. A resistance device is coupled to the seat pad or elsewhere for providing resistance to reciprocal back-and-forth motion of the handles, and two mechanical stops are provided, one on each side of the apparatus, for limiting rotation of the seat pad. The mechanical stops each have plural settings for adjusting a maximum angle of rotation of the seat pad. The apparatus also includes a back pad coupled to the support, which is adjustable along the longitudinal axis.

[ What is claimed is:] [27.] An apparatus for manipulating a user's back while supporting the user's back and hips, said apparatus comprising:a linear support defining a longitudinal axis;a seat pad disposed along the linear support at a position corresponding to the user's hips, the seat pad (1) supporting the user's hips, (2) being rotatable around the longitudinal axis, and (3) having an attached seat belt for holding a user on the seat pad;a pair of upwardly extending handles for grasping by the user, one on each side of the seat pad, which are mechanically coupled to the seat pad and which are movable in reciprocal back-and-forth motion to control rotation of the seat pad around the longitudinal axis;a pair of substantially identical couplings which couple each handle to one side of the seat pad so that the seat pad rotates downward in response to a forward motion of a handle and rotates upward in response to a backward motion of the handle, each coupling comprising a rotatable arm having a first pivotable joint coupled to said seat pad and a second pivotable joint coupled to a corresponding one of said handles;a resistance device coupled to the seat pad for providing resistance to reciprocal back-and-forth motion of the handles;two mechanical stops, one on each side of the apparatus, for limiting rotation of the seat pad, the mechanical stops each having plural settings for adjusting a maximum angle of rotation of the seat pad; anda back pad coupled to the linear support, which is adjustable along the longitudinal axis.
