Abstract

A device and method for rehabilitation of patients with kinesthetic injuries. The device consists of a base with non-skid feet to securely locate the device on a supporting surface. An upwardly extending guide member is located on the base. A target attachment with target is attached to the guide member. A repositionable platform assembly with a downwardly extending platform support point is placed at a receiving location on the base. From the upper surface of the repositionable platform extends a wand support with a wand tip at its upper end. Optionally, an anti-rotation member can be used to partially prevent movement of the platform. Such an anti-rotation member interacts with the guide member to restrict platform movement. In one configuration, the anti-rotation member is used to prevent yaw of the platform, but allow roll or pitching motion. In use, the patient attempts to move the platform either in single or multiple directions; i.e., movement may be from front to back, vice-versa, or in side-to-side, or vice-versa, or may combine directional motions into more complex movements such as circular movement or figure eight or other patterns. As a result of the patient induced movement of the platform, the wand moves relative to the target. Rehabilitative progress can be measured with instant visual feedback by comparing the accuracy of the resultant movement with the desired movement attempted.

Claims

1. A rehabilitation training device, said device comprising:

(a) a base assembly, said base assembly comprising

(i) a base, said base having an upper portion and a rear portion,

(ii) a pivot support point receiving location on the upper portion of said base,

(iii) an upwardly extending guide member affixed to said rear portion of said base,

(iv) an upwardly extending target attachment means, said target attachment means mounted from and transverse to said guide member and extending therefrom to a location over said base, and

(v) a target, said target attached to said target attachment means; and

(b) a platform assembly, said platform assembly comprising

(i) a platform, said platform having at least one downwardly extending pivot support point, said pivot support point adapted to being placed on and thereby received in said pivot support point receiving receiving location of said base so that said platform is repositionable in three degrees of motion about multiple axes;

(ii) a wand support means, said wand support means attached to said platform,

(iii) a wand member extending upwardly from said wand support means,

(iv) a wand tip extending from said wand member,

whereby said wand tip extends upward from said wand member and may be repositioned with respect to said target wherein the user places at least one limb on the platform and directs the wand tip in various patterns of motion relative to the target thereby receiving visual feedback on his kinesthetic abilities.

2. The device of claim 1, wherein said platform assembly further includes an anti-rotation member, said anti-rotation member being affixed to said wand support means and extending radially outwardly therefrom so as to interact with said guide member of said base so as to tend to prevent the platform member from yaw motion, whereby said platform is substantially repositionable only in two axes, namely with respect to pitching and rolling motion.

3. A method of therapy for a patient utilizing the device of claim 1, wherein a patient repositions said platform by rolling said platform from side to side, wherein said repositioning results in movement of said wand tip, and wherein the position of said wand tip may be compared by the patient to the position of said target, so as to obtain feedback regarding the success of the repositioning effort by a patient.

4. A method of therapy for a patient utilizing the device of claim 1, wherein a patient repositions said platform by pitching said platform from end to end, wherein said repositioning results in movement of said wand tip, and wherein the position of said wand tip may be compared to the position of said target, so as to provide feedback regarding the success of a patient'"'"'s repositioning effort.

11. The device as set forth in claim 1 or claim 5, wherein said platform assembly further comprises a first pin attached upwardly from said platform at a location spaced radially outward from said wand support portion, said pin adapted to receive a weighting member, so that said platform may be used by a patient with application of pressure to the platform from a single limb.

13. The device as set forth in claims 2 or 7, wherein said wand support portion further comprises a laterally oriented attachment portion which defines an aperture for receipt therein of said first end of said anti-rotation rod.

14. The device as set forth in claims 2 or 7, wherein said guide member further comprises a pair of opposing wedge shaped walls which define an aperture for passage therethrough of said anti-rotation rod.

5. A rehabilitation training device, said device comprising:

(a) a base assembly, said base assembly comprising

(i) a base, said base having an upper portion and a rear portion,

(ii) a pivot support point receiving location on the upper portion of said base,

(iii) an upwardly extending guide member affixed to said rear portion of said base,

(iv) an upwardly extending target attachment member, said target attachment member mounted from said guide member and comprising a portion extending outwardly from the position of said guide member to a location over said base, and

(v) a target, said target attached to said outwardly extending portion of said target attachment member; and

(b) a platform assembly, said platform assembly comprising

(i) a platform, said platform having at least one downwardly extending pivot support portion, said pivot support portion adapted to being placed on and thereby received in said pivot support point receiving location of said base, so that the platform is repositionable in three degrees of motion about multiple axes;

(ii) a wand support portion, said wand support portion attached to said platform,

(iii) a wand member extending upwardly from said wand support portion,

(iv) a wand tip extending from said wand member, whereby said wand tip extends upward from said wand member and may be repositioned with respect to said target wherein the user places at least one limb on the platform and directs the wand tip in various patterns of motion relative to the target thereby receiving visual feedback on his kinesthetic abilities.

6. The device as set forth in claim 5, wherein said target attachment member comprises a target support rod and said outwardly extending portion further comprises a target locator rod, and wherein said target support rod extends upwardly from said guide member, and said target locator rod extends transversely from said target support rod, so that said target may be positioned at a point over said base.

7. The device as set forth in claim 5, wherein said outwardly extending portion of said target attachment member extends radially from said portion of said guide member to a point over said base.

8. The device as set forth in claim 5, wherein said outwardly extending portion of said target attachment member extends radially from said portion of said guide member to a point over said platform.

9. The device of claim 5, wherein said platform assembly further includes an anti-rotation member, said anti-rotation member being affixed at a first end to said wand support portion and extending radially outwardly therefrom so as to interact with said guide member of said base so as to tend to prevent the platform member from yaw motion, whereby said platform is substantially repositionable only in two axes, namely with respect to pitching and rolling motion.

10. The device as set forth in claim 5, wherein said pivot support point and said wand support portion each include interfitting attachment means whereby said pivot support point and said wand support portion may be joined at via said interfitting attachment means to secure said platform therebetween.

12. The device as set forth in claim 6 wherein said target support rod and said wand member are each provided in a preselected height, said heights of said target support rod and said wand member is configured to be sufficiently long for movement of said wand member on said platform with respect to said target support rod by manipulation of said platform by the lower extremities of a patient while viewing said target and said wand member while a patient is in a sitting position.
