Abstract: An apparatus for performing soft-tissue manipulation of a user's spinal discs, and other back, neck and glutei soft-tissues includes a rigid or semi-rigid working member having at least one operational side surface for engaging contact with target soft-tissues and to which are secured a pair of straps. The operational side surface is provided with design form features configured to produce a therapeutic effect on the target soft-tissues when in contact therewith, and which may include recesses, projections or other protuberances. The working member and straps have an overall longitudinal length selected to enable the apparatus to be positioned partially encircling a user's body with the straps secured to a support. The length enables the user to stand or sit in a rearward inclined position, leaning backwardly to effect relative bearing contact between the target soft-tissues and the operational surface of the working member.
