This application is a continuation in part of U.S. patent application Ser. No. 12/258,697, filed Oct. 27, 2008, which is dependent on and claims priority from earlier filed U.S. Provisional Patent Application No. 60/982,846, filed Oct. 26, 2007; earlier filed U.S. Provisional Application No. 61/014,822, filed Dec. 18, 2007; and earlier filed U.S. Provisional Application No. 61/086,608, filed Aug. 6, 2008.

BACKGROUND OF THE INVENTION

The present invention relates generally to a device for use in connection with rehabilitation therapy and general exercise. More specifically, the present invention relates to a collapsible exercise platform that includes an interchangeable user interface mounted within its base platform that facilitates proper exercise posture and positioning while simultaneously working a broad range of muscle groups.

It is well known in the art that therapeutic exercise is important and is widely accepted as a means for treating and relieving a variety of human disabilities. Additionally, exercise plays a crucial role in the rehabilitation of patients suffering from various injuries. A physical therapist's role in such a rehabilitative context is to provide rehabilitative professional care that individually tailors exercise programs to meet a patient's needs. These tailored rehabilitative exercise programs differ depending on the type and amount of damage to the injured area, stage of tissue healing, age of the person, and prior level of function of the individual prior to injury.

Some of the most common early rehabilitation methods consist of isometric exercise, continuous passive motion (CPM) machines and/or active assisted range of motion (ROM) performed by a therapist on a patient. While isometric exercise is a good way to initiate strength into newly repaired tissue, the benefits are limited in that such fixed motion therapies as are provided through CPM are too concentrated requiring that ROM exercises also be implemented in order for the patient to normal or pre-surgical levels of movement. The problem with therapist implemented ROM, however, is that such therapy is labor intensive, costly and infrequent. This then requires a return to a set of limited exercises being given to patients for a home program that consists usually, but not solely, of isometric muscle setting exercises. These exercises generally do not involve sufficient ranges of joint movement and therefore have limited benefit in the rehabilitative setting. Additionally, exercises that are usually instituted later in the rehabilitation process utilize a resistive band and may provide less stability to the joint making them generally less comfortable, therefore, usually yielding less patient compliance. Finally, patients may be given a variety of exercises that involve open and closed chain activity. These can place an unwanted compressive or shear force on the joints should they be performed incorrectly.

In other contexts beyond rehabilitative therapy, regular exercise is also known to keep the body in good shape, but not all such exercise is equally effective. In fact, many of the exercise devices that are marketed or provided in health and athletic clubs, are actually less effective than people realize. That is not to say that the majority of the exercise equipment that is provided in health clubs is not beneficial provided that the user gets proper instruction under the guidance of a trainer. The primary issue is that most of the equipment employed in health clubs trains using predominantly linear, single plane movement and as a result is limited to isolating one muscle group while allowing other muscle groups to rest. Examples of this type of exercise can be put into two categories. The first is the leg press, a closed chain activity and the second exercise is the leg extension, which is an open chain exercise. Generally, neither of these exercises is considered ideal for knee or hip rehabilitation. While, this type of training may be appropriate for an athlete or one who has a balanced workout regimen, this type of isolated, open chain, planar movement is not how the body typically moves in reality.

Ultimately, in either of the rehabilitative or exercise contexts it must be understood that the body rarely moves in just one plane. Often the body must employ multiple muscle groups and balance them in a cooperative fashion to reach the desired end result. Further, most body movement involves rotation and diagonal patterns of movement. For example, taking a step requires combined movements of plantar flexion, internal hip rotation, foot pronation/supination, knee extension and hip extension. The difficulty of the overall problem can be seen in the fact that if the human body only moved in single planes it would be easy to construct a mechanical hand, foot or leg that mirrors human movement. However, it is very difficult to replicate such realistic human movement because it is not defined through such one or two-dimensional movements.

The complex nature of human movement has created a specialized field of Proprioceptive Neurofacilitation (PNF) within physical medicine. PNF believes that the best form of rehabilitation for musculoskeletal injuries is implemented using diagonal patterns through multiple planes of movement. However, this treatment technique requires a purely hands-on, manual approach and is extremely demanding of therapist skill and training. The therapist presently practicing PNF must personally take the patient through the motions and provide appropriate resistance for the patient's need and present physical limitations.

Accordingly, there is a need in the therapeutic and/or conditioning exercise equipment art for an apparatus that provides structured, multiaxial, multi-pattern movement that aids in rehabilitation or enhances conditioning. Further, there is a need for an apparatus that provides structured, multiaxial, multi-pattern movement that would allow the patient to control for different muscle patterns and that that can be employed equally by the average healthy person or someone recovering from hip, knee or ankle injury. Further still, there is a need for a device that enables a user to obtain multidimensional exercise that also provides multiple embodiments and would allow the user to progress toward full rehabilitation through the isolation of muscle groups by mirroring the difficulty and complexity of movement.

BRIEF SUMMARY OF THE INVENTION

In this regard, the present invention generally provides a therapeutic and/or exercise apparatus that provides structured, multiaxial, multi-pattern movement that aids in rehabilitation or enhances conditioning. By using the apparatus of the present invention an average healthy person or a patient recovering from hip, knee or ankle injury can equally participate in exercise and rehabilitation activities targeted to different muscle groups and exercise patterns. As a result, the apparatus of the present invention enables a user to obtain multidimensional exercise that allows the user to progress toward full rehabilitation through the isolation of muscle groups by mirroring the difficulty and complexity of realistic human movement.

The apparatus of the present invention generally includes a base portion and a posture bar that is attached to and extends upwardly from the base portion. The posture bar is affixed to a top surface of the base portion and can be removable or collapsible for ease of storage. The posture bar serves to assist the user in maintaining correct posture and/or body alignment during exercise activities. The base portion interfaces on a bottom surface with a floor or other stable surface, while the top surface includes a recess therein for receiving one of a variety of controlled motion device such as a rotary disk that moves freely or is restrained by resistance means or other proprioceptive tools. This feature of the present invention provides a much more balanced exercise process while also naturally working the entire set of muscle groups related to the exercise rather than simply isolating a single motion or muscle.

The rotary disc may further be enhanced with a locking mechanism that can be released to allow a full 360-degrees of rotational movement or engaged to stop the rotary disc from moving at all. Further, the rotary disc may include an indexing mechanism that allows for a specifically defined rotation. For example, a turn and click feature allows the disc to be turned over a limited rotation in both internal and external movement.

Finally, the present invention provides for attachment points on the base portion that allow various resistive or constant motion assemblies to be attached.

In this regard, resistive bands, pulleys, handles, cables and various combinations thereof can be attached that are employed in various different exercises while the user is positioned on the base portion. Bands are employed for constant resistive exercises while a single resistance band may be used in combination with one or more pulley to create variable resistance exercises. Further the pulleys and cables may be arranged in a looped manner that allows a constant motion type exercise.

It is therefore an object of the present invention to provide a therapeutic and/or conditioning exercise equipment art for an apparatus that provides structured, multiaxial, multi-pattern movement that aids in rehabilitation or enhances conditioning. It is a further object of the present invention to provide an apparatus that provides structured, multiaxial, multi-pattern movement that requires the user to employ a full and free range of motion while performing the required exercises. It is still a further object of the present invention to provide an exercise apparatus invention that results in core strengthening through the use of proprioceptive tools that require that broad ranges of muscles be involved in each exercise rather than simply working targeted muscle groups.

These together with other objects of the invention, along with various features of novelty that characterize the invention, are pointed out with particularity in the claims annexed hereto and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated a preferred embodiment of the invention.

DETAILED DESCRIPTION OF THE INVENTION

Now referring to the drawings, the apparatus of the present invention is generally depicted atFIGS. 1,2 and3 whileFIGS. 4 and 5 depict various modes of operation for the apparatus. As can be seen, the present invention generally provides a therapeutic and/or exercise apparatus for use in performing structured, multiaxial, multi-pattern movement that aids in rehabilitation or enhances conditioning. By using the apparatus of the present invention an average healthy person or a patient recovering from hip, knee or ankle injury can equally participate in exercise and rehabilitation activities targeted to different muscle groups and exercise patterns. As a result, the apparatus of the present invention enables a user to obtain multidimensional exercise that allows the user to progress toward full rehabilitation through the isolation of muscle groups by mirroring the difficulty and complexity of realistic human movement.

Turning toFIGS. 1 and 2, theapparatus10 of the present invention can be seen to generally include abase portion12 and aposture bar14 that is attached to and extends upwardly from thebase portion12. Theposture bar14 is affixed to atop surface16 of thebase portion12. More preferably, theposture bar14 is affixed to thebase portion14 in a manner that allows it to be easily detached or repositioned for storage. In this regard, theposture14 bar may be fully removable or hingedly attached to thebase portion12 thereby allowing it to be folded against thebase portion12 for storage purposes as seen inFIG. 2. Theposture bar14 is rigidly affixed to thebase portion12 of the present invention and serves as a reliable structural support to assist the user in maintaining correct posture and/or body alignment so that the user can properly execute the various exercise activities. In addition, it can be seen that the height of theposture bar14 is adjustable via the springbiased pin18 along the side thereof and thehandles20 are ergonomic so that theposture bar14 facilitates perfect alignment of the user's body and so that it can accommodate users of differing sizes. In operation, a user may hold onto theposture bar14 or lean their front back or side against theposture bar14 to perform exercises as will be described in more detail below. Further, thehandles20

posture bar

14 may extend along the user's sides or fully around the user as well.

Thebase portion12 interfaces on a bottom surface with a floor or other stable surface. Ideally the lower surface of thebase portion12 has a sufficiently wide contact surface that allows thebase portion12 to remain stable throughout various exercise activities. Additionally, the bottom surface of thebase portion12 may include a nonslip surface to keep the apparatus from sliding across the support surface and may further include small feet to support the four corners of thebase portion12. Further, if feet are provided, they may be of the leveling type to further enhance the stability of thebase portion12 when used on uneven support surfaces.

Thetop surface16 of thebase portion12 includes arecess22 therein for receiving one of a variety of controlled motion devices. In the preferred embodiment, as depicted in the figures, therecess22 can be seen to include arotary disk24 installed therein. Therotary disk24 freely rotates within therecess22 and relative to thebase portion12. Preferably, therotary disk24 is received within therecess22 and is supported by a bearing that enhances the ability of therotary disk24 to freely and smoothly rotate. It can also be seen that therotary disk24 andbase portion12 includeindex markings26 thereon so that therotary disk24 is indexed relative to thebase portion12 to assist a user in positioning their body in the correct positions for the exercise they are performing. Theindex markings26 further allows a user to measure various performance vectors relative to range of motion. For example, one exercise may request that a user place their left foot onto therotary disk24 with it aligned at the 12 o'clock index marking26 and then rotate it to the 9 o'clock index marking26 to perform the exercise. Similarly, an exercise may require that a user repetitively rotate between the 12 o'clock position and the two o'clock position. Further, when performing various stretching and resistive exercises as will be described in detail below, the user stands on therotary disk24 such that they must balance their body motions in a manner that resists the naturally induced rotation of therotary disk24. For example as a user bends at the knee the foot naturally tends to pronate inducing rotation of therotary disk24. The exercise in turn requires that the user resist this rotation as they bend at the knee. This feature provides a much more balanced exercise process while also naturally working the entire set of muscle groups related to the exercise rather than simply isolating a single motion or muscle.

It should be noted in the context of the present invention that theindex markings26 on therotary disk24 for indexing movement of therotary disk24 relative to thebase portion12 are shown as analog. Suchanalog index markings26 are not intended to be limiting on the scope of the invention in that thebase portion12 may employ electronics for indexing the rotation of therotary disk24 thereto. In this manner, therotary disk24 may include any type of electronic indexing arrangement thereon, such as for example magnets, optical vanes, physical protrusions or any other means known in the art for indexing the rotational movement of therotary disk24. Similarly, thebase portion12 may include corresponding indexing devices such as an optical beam that reads the passing optical vanes, a switch that reads the passing physical protrusions a sensor that reads the passing magnets or a wheel that tracks the rotation of therotary disk24 directly. In any case, the intent is to provide a means for reading and electronically tracking the movement of therotary disk24.

Once the information regarding the rotational movement and relative position of therotary disk24 is available, such information may be utilized by the apparatus of the present invention in many ways. For example, the system can measure the right to left rotation and the internal to external rotation of the same joint thereby assisting in identifying potential injury areas. Further, a interactive screen that shows the user various movements to be performed in order to test the users stability and proprioception. Similarly interactive games may be employed that detect the user's various positions including their balance, strength and posture to assist in rehabilitating or retraining the user's movements.

Turning now toFIG. 3, thebase portion12 is depicted in a close view wherein thehinge point28 for the attachment of theposture bar14 can be seen. In addition, therotary disk24 can be seen received in therecess22 on top of thebase portion12.Index markings26 can be seen both on thetop surface16 of thebase portion12 as well as on therotary disk24 to allow the user to align therotary disk24 as necessary. Further, hooks30 can be seen positioned along the front edge of thebase portion12. Thehooks30 are positioned as rigid attachment points for resistance bands, pulleys and the like to enhance or supplement the various exercise routines performed using theapparatus10 of the present invention.

Turning toFIG. 4, for example,resistance bands32 can be seen affixed to thehooks30 and to apin34 on therotary disk24. In accordance with the present invention, various different mechanisms may be employed with therotary disk24 to enhance the overall range of features provided. For example, therotary disk24 may be enhanced with a locking mechanism that can be released to allow a full 360-degrees of rotational movement or engaged to stop therotary disk24 from moving at all. In addition, therotary disk24 may include an internal variable resistance arrangement. This may includeextensible resistance bands32 that are affixed to thehooks30 that are positioned either under or above therotary disk24 or an adjustable band clamp that engages against a braking drum under or above therotary disk24 thereby resisting rotation of therotary disk24 in an adjustable and variable manner. Alternately, the variable resistance arrangement may be magnetic wherein the increase of voltage applied to an electromagnetic coil will serve to increase the overall force required to cause therotary disk24 to turn. This arrangement allows the user to have more control over the movement of the disc and also can serve to provide additional resistance that enhances the exercise routine as the user's body must work against the additional resistance. It also allows the variable resistance mechanism to work in concert with the electronic indexing arrangement to control or limit rotation of therotary disk24. Further, therotary disk24 may include a mechanical indexing mechanism that allows for a specifically defined rotation. For example, a turn and click feature allows therotary disk24 to be turned over a limited rotation in both internal and external movement.

In addition to therotary disk24, the present invention anticipates that other proprioceptive tools can be inserted into therecess22 including but not limited to a rocker board similar to a see-saw, a ball device or a soft surface. These additional tools assist in enhancing balance while involving various muscle groups in the lower extremities as well as posture related muscles in the back throughout the exercise process.

Turning toFIG. 5, the present invention can be seen to further provide attachment points such as thehooks30 on thebase portion12 that allow various resistive or constant motion assemblies to be attached. In this regard, resistive bands, pulleys, handles, cables and various combinations thereof can be attached that are employed in various different exercises while the user is positioned on the base portion.Resistive bands32 are employed for constant resistive exercises while asingle resistance band32 may be used in combination with one or more pulley to create variable resistance exercises. Further, the pulleys and cables may be arranged in a looped manner that allows a constant motion type exercise.

It can therefore be seen that the present invention provides an exercise and rehabilitation tool that requires the user to employ a full and free range of motion while performing the required exercises. This arrangement allows testing and isolation of certain muscle groups for strength testing while the body is maintained in a correct anatomical position. Further, the present invention allows core strengthening in that rather than simply working targeted muscle groups, the proprioceptive tools require that broad ranges of muscles be involved in each exercise. For these reasons, the instant invention is believed to represent a significant advancement in the art, which has substantial commercial merit.

While there is shown and described herein certain specific structure embodying the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
