A back-therapy apparatus for vertebral massage comprises at least one first manipulating element (743) comprising a first engagement member (744) and at least one second manipulating element (743) comprising a second engagement member (744). The first and second engagement members (744) are arranged such that, in use, they are each situated on opposite sides of a patient's vertebral column. The first engagement member (744) is operable to contact and manipulate vertebral area between the spinous and transverse processes from one side of the vertebral column and the second engagement member (744) is operable to contact and manipulate the vertebral area between the spinous and transverse processes from the opposite side of the vertebral column. The first and second manipulating elements (743) are operable independently of each other to move the first and second engagement members (744) respectively into and out of contact with the vertebral area between the spinous and transverse processes thereby manipulating rotational movement of the vertebral column.
