A shaped block that can be used for chiropractic treatment. The block has a base, a rear end face, an upper face parallel to the base and merging with the upper edge of the rear end face, a rectangular front end face merging with the front end of the base, and an upper oblique portion between the upper face and the front end face inclined between 60 DEG to 85 DEG . The oblique portion has a first upper inwardly curved section descending from an inner edge of the upper face, an intermediate flat face portion following the first curved section and raised above the plane of the oblique portion, and lifted 7 DEG to 9 DEG at the lower end, and a lower curved section between the intermediate flat face and the second end face. Irregular faces connect these parts together into a block. The faces of the curved section are anti-skidding so as to engage human body portion under treatment while preventing it from sliding along the curved surfaces. The block is made of soft rubbery material. A handle may be provided at the rear end to manipulate the block. For treatment, the blocks are used in pairs. For a right handed person, one block is inserted underneath the person lying on his back so as to rest below the right ischium against the oblique portion of one block, the block being oriented transversely with the lower front end corner pointing towards the groin area of the body of the person, and the second block is inserted underneath the same person with the oblique portion immediately below the left ischium with the upper front end corner pointing towards the groin area.
