## Abstract

A back therapy apparatus for vertebral massage includes a plurality of manipulating assemblies. The apparatus is adjustable and arranged to engage a spine at multiple locations over an extended length at vertebral areas between a spinous process and a transverse process on either side of a spine. A drive system is adapted to drive multiple manipulating assemblies simultaneously and independently.

## Claims

### Claim 1

Back therapy apparatus operable to apply vertebral massage to a person's back, the apparatus comprising:
a support frame;
a plurality of first manipulating elements movably mounted with respect to the support frame and each one of the plurality of first manipulating elements having a respective first engagement member thereon;
a plurality of second manipulating elements movably mounted with respect to the support frame and each one of the plurality of second manipulating elements having a respective second engagement member thereon;
a controller operable to control actuators coupled to the first and second manipulating elements to effect individual displacement of the first manipulating elements independent of the second manipulating elements with respect to the support frame, wherein the first and second engagement members are each moveable from a direction substantially perpendicular to the person's back to a direction that is substantially parallel to the person's back by a respective first and second guide;
wherein the first and second engagement members are arranged such that, in use, they are arranged and distributed along the length of the vertebral column, wherein the first engagement members are situated on one side of the vertebral column and the second engagement members are situated on an opposite side of the vertebral column wherein the first and second manipulating elements are arranged in pairs, wherein each first manipulating element is associated with a corresponding second manipulating element;
wherein each first engagement member is operable to contact and manipulate a first vertebral area between spinous and transverse processes from one side of the vertebral column and each second engagement member is operable to contact and manipulate a second vertebral area between spinous and transverse processes from the opposite side of the vertebral column, wherein the first manipulating elements facilitate movement of one or more of the first engagement members into and out of contact with the vertebral area between the spinous and transverse processes separate from movement of a corresponding adjacent one or more of the second engagement members thereby manipulating displacement of the vertebral column, wherein the controller is operable to control amplitude of displacement of the first and second engagement members and wherein the controller is operable to control each of the first and second manipulating elements individually or in banks of two or more wherein the controller is operable to control and/or program a sequence of movements of the first and second manipulating elements, to create movement of the spine towards both sides, by controlling the first and second engagement members to at least partially engage the area of the spine between the spinous and transverse processes, by applying force towards the base of the area from each one of their sides and then create a first movement by applying forces towards one side first and then towards the opposite side, to compensate the first movement, wherein the apparatus is adaptable to shapes and contours of a person's vertebral anatomy and arranged to apply a force simultaneously along the length of the spine thereby to provide therapy along the full length of the spine.

### Claim 2 (depends on 1)

A back-therapy apparatus according to claim 1, wherein the first and second manipulating elements are each operable to facilitate movement of the first and second engagement members from the direction substantially perpendicular to the person's back to the direction that is substantially parallel to the person's back and from the direction that is substantially parallel to the person's back to the direction that is substantially perpendicular to a person's back.

### Claim 3 (depends on 1)

A back-therapy apparatus according to claim 1, wherein the first and second manipulating elements are each operable to facilitate movement of the engagement members into and out of contact with the vertebral area between the spinous processes and the transverse processes at an angle between perpendicular and parallel to the person's back, wherein pressure is applied in a direction towards the opposite side of the person's vertebral column from the side at which the respective engagement member is located.

### Claim 4 (depends on 1)

A back-therapy apparatus according to claim 1, wherein the first and second manipulating elements comprise a sensing element operable to sense load and/or displacement of the first and second engagement members when in contact with the vertebral area between the spinous and transverse processes; and being operable to provide feedback of said displacement and/or force as an indication of vertebral stiffness or pain.

### Claim 5 (depends on 1)

A back-therapy apparatus according to claim 1, wherein the first and second manipulating elements are operable to adjust the first and second engagement members' orientation respectively, such that the apparatus is adaptable to shapes and contours of a person's vertebral anatomy.

### Claim 6 (depends on 1)

A back-therapy apparatus according to claim 1, wherein the position of the first and second engagement members relative to adjacent and corresponding first and second engagement members and relative to the vertebral area between the spinous and transverse processes is adjustable responsively in contact with the vertebral area between the spinous and transverse processes.

### Claim 7 (depends on 1)

A back-therapy apparatus according to claim 1, wherein the first and second manipulating elements comprise jointed members.

### Claim 8 (depends on 1)

### Claim 12 (depends on 1)

A back-therapy apparatus according to claim 1, wherein the controller is operable to sense or measure displacement from each of the first and second manipulating elements and/or first and second engagement members thereby being operable to identify stiffness in a person's vertebral column.

### Claim 13 (depends on 1)

A back-therapy apparatus according to claim 1, wherein the first and second manipulating elements emulate fingers and the first and second engagement members emulate fingertips.

### Claim 14

A massage table incorporating the back-therapy apparatus comprising:
a support frame;
a plurality of first manipulating elements movably mounted with respect to the support frame and each one of the plurality of first manipulating elements having a respective first engagement member thereon;
a plurality of second manipulating elements movably mounted with respect to the support frame and each one of the plurality of second manipulating elements having a respective second engagement member thereon;
a controller operable to control actuators coupled to the first and second manipulating elements to effect individual displacement of the first manipulating elements independent of the second manipulating elements with respect to the support frame, wherein the first and second engagement members are each moveable from a direction substantially perpendicular to the person's back to a direction that is substantially parallel to the person's back by a respective first and second guide;
