90242-1 A massaging apparatus for adjusting the clearances of intervertebral discs and articulations is disclosed which is pivotally mounted on a support frame proximate one of its ends and is provided with a reciprocating member. The reciprocating member is reciprocated along a side bearing and a lower bearing on the inner surface of the main frame. An elevation adjustment device supports the main frame proximate its other end and comprises an adjustable screw rod which is rotated by a driving motor threadedly mounted in hinge supports of two pair of hinge arms foldably operating between the top support and the lower support of the elevation adjustment device. By rotating the adjustable screw rod clockwise or counterclockwise, a user is conveniently and easily elevated with the elevation adjusment device, and the degree of declination of the main frame from horizontal may be selectively adjusted. |
