Abstract: A muscular therapy treatment apparatus for patient self-treatment in applying concentrated pressure to deep muscle attachments in the lamina groove on either side of the spinous processes of spine vertebrae to relax and lengthen the muscles therein and cause vertebrae alignment without the forcing of bone. Each embodiment of the apparatus has a rigid planar base support and a treatment member depending upwardly therefrom with a pair of sharp edges on its curved upper peripheral surface. A groove separates the sharp edges and receives the spinous processus of vertebrae when a patient becomes positioned on top of or against the peripheral surface during use. The groove can have straight interior walls intersecting at an angle between 60.degree. to 70.degree., or it can have an arcuate configuration. The present invention discloses a variety of partial-spine treatment embodiments, as well as a whole-spine treatment embodiment that allows all of the muscles flanking the spinal column to be treated at once.
