## Abstract

A system and method are disclosed that allows a practitioner to rotate a human subject in three different axes of rotation, independently from one another and without limitation on the degree of rotation, which allows for the treatment of various systems of the human subject.

## Claims

### Claim 1

A system for rotation of a human body in three-dimensional space comprising:
a yaw frame contained within a roll frame, wherein the yaw frame is driven by a yaw motor to rotate about a yaw axis within the roll frame, and wherein the roll frame is driven by a roll motor to rotate about a roll axis;
a pitch frame contained within the yaw frame, wherein the pitch frame is driven by a pitch motor to rotate about a pitch axis within the yaw frame;
a seat affixed within the pitch frame;
wherein the roll frame, the yaw frame and the pitch frame define a rotational space, and wherein the roll motor, the yaw motor and the pitch motor are located outside the rotational space;
wherein the roll frame comprises an internal drive hub; wherein the yaw motor drives a first internal drive shaft that runs through the internal drive hub; wherein the pitch motor comprises a second internal drive shaft that runs through the internal drive hub.

### Claim 2 (depends on 1)

The system of claim 1 further comprising:
a support frame comprising the roll drive motor coupled to a roll drive wheel, wherein the roll drive wheel is in contact with the roll frame, wherein rotation of the roll drive wheel causes rotation of the roll frame about a roll axis;
a yaw drive system comprising the yaw drive motor coupled to a yaw drive belt, wherein the yaw drive belt is coupled to the first internal drive shaft, wherein the yaw drive shaft is coupled to a yaw drive actuator, wherein the yaw drive actuator is coupled to the yaw frame;
a pitch drive system comprising the pitch drive motor coupled to a first pitch drive belt, wherein the first pitch drive belt is coupled to the second internal drive shaft; wherein the second internal drive shaft is coupled to a second pitch drive shaft; wherein the second pitch drive shaft is coupled to a pitch drive actuator, wherein the pitch drive actuator is coupled to the pitch frame.

### Claim 3 (depends on 2)

The system of claim 2 wherein the roll frame comprises an annular truss, a plurality of axial trusses extending from the annular truss, and a plurality of radial trusses that meet at the internal drive hub.

### Claim 4 (depends on 2)

The system of claim 2 wherein the roll frame comprises a circumferential drive belt that engages with the roll drive wheel.
