The therapeutic device of claim 1, wherein the motorized roller assembly includes a motor unit that has a motor and a motor drive shaft that is operatively coupled to the pair of rotors for causing controlled rotation of the pair of rotors.

The therapeutic device of claim 4, wherein each rotor includes a center portion through which the drive shaft passes and a plurality of spoke sections extending radially outward from the center portion, wherein each rotor is connected between one spoke of one rotor and one spoke of the other rotor.

The therapeutic device of claim 5, wherein each end of each roller has a roller shaft extending outwardly therefrom, each roller shaft being received within an opening formed in one of the respective rotors to allow each roller to freely rotate between the pair of rotors.

The therapeutic device of claim 1 , wherein the housing including a first base plate that represents a bottom of the therapeutic device and is configured to attach to the upper portion, and the pair of rotors are rotatably supported by a rotor bracket that is movably coupled to the first base plate.

8. The therapeutic device of claim 7, wherein the rotor bracket comprises a second base plate and a pair of upstanding side walls that extend upwardly from the second base plate, the pair of rotors and the plurality of rollers being disposed between the upstanding side walls.

9. The therapeutic device of claim 8, wherein the motorized rotor assembly includes a motor unit that has a motor and a motor drive shaft that is operatively coupled to a pair of rotors hubs for causing controlled rotation of the pair of rotors, the motor drive shaft passing through the pair of rotor hubs and the pair of upstanding side walls to permit the rollers to rotate in unison between the pair of upstanding side walls.

10. The therapeutic device of claim 8, wherein the second base plate is pivotally coupled to the first base plate and a biasing element is provided between the second base plate and the first base plate and applies a biasing force against an underside of the second base plate.

11. The therapeutic device of claim 8, further including a pair of cams that are

disposed along outer faces of a pair of rotor hubs and are coupled to a drive shaft of a motor that drives the rotors, each cam having at least one cam surface that selectively contacts a cam pin that is fixedly attached to an inner face of one of the side walls to cause translation of the rotor assembly relative to the second base plate.

12. The therapeutic device of claim 11, further including a percussive side mechanism comprising a pair of percussive slide housings mounted to outer faces of the upstanding side walls of the second base plate, wherein each percussive slide housing including a percussive slide operatively coupled to the drive shaft of the motor and biased in the percussive slide housing by a biasing element that is disposed between one end of the percussive slide housing and the percussive slide and applies a biasing force to the percussive slide, the percussive slide being permitted to slidingly travel within the percussive slide housing in a first direction as a result of the at least one cam surface contacting the cam pin and in a second direction when the at least one cam surface passes and is free of contact with the cam pin.

13. The therapeutic device of claim 10, further including a vibration motor that is coupled to the second base plate and transmits vibrational energy to the second base plate and rotor assembly for providing a vibration treatment to the neck.

14. The therapeutic device of claim 12, wherein each of the pair of upstanding side walls includes a slot for receiving the drive shaft of the motor and permitting axial movement of the drive shaft of the motor as a result of the transmission of percussive energy.

15. The therapeutic device of claim 1, wherein each roller includes a pair of roller contact lobes with a center relief portion for accommodation of spinal processes.

16. The therapeutic device of claim 15, wherein at least one roller has a roller

diameter of about 1.50 inches; a recess depth of about 0.46 inches and a roller lobe width of about 1.25 inches.

17. A therapeutic device for stimulating the anatomy of the cervical spine and neck of a user comprising:

a housing having an upper portion configured for receiving the cervical spine and neck of the user; and

a motorized rotor assembly at least partially contained within the housing and having a plurality of rollers, the motorized rotor assembly rotating about a first axis and having a plurality of rollers that are coupled to and disposed between a pair of rotor hubs, the plurality of rollers rotating independently from one another and about axes that are spaced from the first axis;

wherein each roller comprises a body defined by two roller contact lobes formed at ends of the roller, with a relief portion being formed between the two roller contact lobes and being configured to accommodate spinal processes of the cervical spine, while the two roller contact lobes are configured for contacting the facet joints of the cervical spine.

18. The therapeutic device of claim 17, wherein each roller has an hourglass shape.

19. The therapeutic device of claim 17, wherein each roller has a shaft component that is received within openings formed in a rotor bracket to which the motorized rotor assembly is mounted.

20. The therapeutic device of claim 19, wherein the motorized rotor assembly

includes a power unit that is coupled to the motorized rotor assembly to controllably rotate the rotor hubs and the plurality of rollers, wherein the motorized rotor assembly and the power unit are floating members in that the

motorized rotor assembly and power unit are free to move in an up and down direction within the housing and are free of fixed attachment to the housing.

21. A therapeutic device for stimulating the anatomy of the cervical spine and neck of a user comprising:

a housing having an upper portion configured for receiving the cervical spine and neck of the user and having an opening formed therein;

a motorized rotor assembly at least partially contained within the housing and having a plurality of rollers that are supported on a rotor bracket, with at least one roller protruding from the opening in the housing, the motorized rotor assembly rotating about a first axis and having a plurality of rollers that are coupled to and disposed between a pair of rotor hubs, the plurality of rollers rotating

independently from one another and about axes that are spaced from the first axis, wherein the motorized rotor assembly transmits rotary energy to the cervical spine and the neck as a result of contact of repeated contact between the plurality of rollers and the neck; and

a percussive energy transfer mechanism comprising a pair of cams that are mounted to outer faces of the rotor hubs and fixed cam pins that protrude inwardly from the rotor bracket and are positioned to selectively contact the cams as the motorized rotor assembly rotates resulting in the motorized rotor assembly moving in an up and down direction which is translated into transmission of percussive energy to the cervical spine and the neck.

22. A method for therapeutically stimulating the anatomy of the cervical spine and neck of a user comprising the steps of:

repeatedly contacting a target area of the neck with a plurality of rollers that are rotatably coupled to a rotatable rotor assembly resulting in transmission of rotary/rolling energy to the target area, each roller being independently rotatable relative to one another and along an axis spaced from a main axis of rotation of the rotatable rotor assembly; and

transmitting percussive energy to the target area by causing the rotatable rotor assembly to move in an up and down direction.
