Abstract: Apparatus for exercising the muscles around the cervical spine and/or the motional pattern of the cervical spine with a rotation exercise movement of the head, said apparatus comprising an equipment frame (1), a turning arbor (2) mounted on the equipment frame with bearings permitting rotation of the arbor about a vertical axis, a head rest element (3) for holding the head, said head rest element being connected to the turning arbor (2) and comprising means for holding the head of the person performing the exercise movement substantially immobile in the head rest element.

Abstract: The apparatus includes a link rod (5) pivoted by its first end (6) on the equipment frame via a first joint (7) permitting a turning motion about a swing axis (8) perpendicular to the vertical middle plane of the seat. A head rest (9) is functionally connected to the link rod (5) so that the link rod participates in turning the head rest during an exercise movement while the person's head is leaning against the head rest. The apparatus also includes a multi-joint angular linkage mechanism (12), of which the link rod (5) constitutes a part. The multi-joint angular linkage mechanism (12) is connected to the head rest (9) so as to cause it to move during an exercise movement along a curved path that substantially coincides with the natural path of the neck.
