A device for providing back massage with simultaneous accupressure stimulation along either side of the spine. The device comprises a frame in which are disposed a plurality of rollers which are freely rotatable and capable of being interchangeably positioned within the frame. One roller is of a larger diameter than the remaining rollers and is provided with a central circumferential groove which is bounded on each side by a surface having a plurality of nubs. In use, the nubs contact the user's body on either side of the spine at the desired location to provide accupressure stimulation. By providing the accupressure stimulation roller in a diameter which is larger than the other rollers, the device also provides intervertebral or intersegmental extension during use.
