Referring now to FIG. 2A, a top view of a foot pad for use in one example of a system for enhancing proprioception, balance, and coordination is schematically shown. A foot pad 32 may generally be modeled after the shape of a human footprint, but large enough to accommodate a range of shoe or foot sizes. The foot pad 32 advantageously includes an inner top surface area covered with a non-slip surface 35. The non-slip surface may be any of a variety of commercially available non-slip or non-skid materials that can be glued or otherwise attached to the top surface of the foot pad 32. Alternatively, the non-slip surface can be molded directly into the footpad using, for example, a raised pattern, such as, for example, a crisscross pattern, or similar pattern, for traction.
Referring now to FIG. 2B, a front view of a foot pad featuring an integrated mounting element for use in one example of a system for enhancing proprioception, balance, and coordination is schematically shown. The footpad 32 may advantageously have a sufficient thickness to allow a mounting device 36, such as, for example a “T-track” insertion rail, to be integrated into the foot pad 32 substantially flush with the bottom surface 37 of the foot pad. The various elements of the system may be made using conventional manufacturing techniques as, for example, with molded plastic, nylon, or equivalent materials wherein features such as the rails and tracks are integrated with their respective components as a single molded piece. Other useful materials such as metal, including aluminum and wood may be employed as desired for individual parts.
Referring now to FIG. 2C, a bottom view of a foot pad featuring an integrated mounting element for use in one example of a system for enhancing proprioception, balance, and coordination is schematically shown. The integrated mounting element may advantageously be incorporated by molding it into the foot pad. In another example, the mounting device 36 may be integrated into the foot pad by means of a fastener 38 mounting it to the bottom of the foot pad 32. The fastener 38 may be any useful fastener such as a set of screws, adhesive, nails and the like. In one example embodiment, holding mechanism 40 such as, for example, a set of permanent magnets or the like may be incorporated onto the bottom surface for added stability and to prevent slippage of the foot pad when fastened to the frame.
Referring now to FIG. 3A, a bottom view of the foot pads as mounted on a double-leg platform as employed in one embodiment is schematically shown. The frame 34 comprises double-leg platform for mounting the pair of foot pads 32R, 32L mounted to right and left elongated support elements 42L, 42R attached in parallel to an elongated central support element 41.
Referring now to FIG. 3B, a top view of a double-leg platform as employed in one embodiment is schematically shown. As described above, the frame 34 comprises double-leg platform for mounting the pair of foot pads 32R, 32L. The frame 34 further comprises right and left elongated support elements 42L, 42R attached to an elongated central support element 41 by at least two or, more preferably, three support bars 28. The right and left elongated support elements 42L, 42R are oriented substantially parallel to the elongated central support element 41. Each of the plurality of support bars 28 is attached to substantially form a right angle with the elongated support elements. The support bars 28 may advantageously comprise aluminum tubing or the like for added strength. The support bars may also comprise telescoping parts as described below.
Each of the right and left elongated support elements 42L, 42R have a mounting device 44 for accepting and attaching the foot pads. The central support 41 also includes a similar mounting device 36 for mounting one of the set of fulcrum attachments. The selection of the fulcrum attachment depends on the type of exercise prescribed for the subject or patient. In one example embodiment, a plurality of permanent magnets 40 are distributed on the frame in a pattern that matches the location of opposite-polarity permanent magnets on the attachments and foot pads to hold the attachments and foot pads in place.
Referring now to FIG. 4A, a schematic view of a double-leg platform as employed in one embodiment is schematically shown. For double leg balance two foot pads are attached, via the integrated central track, to a double leg platform. The double leg platform acts to position the balancing fulcrum in the center of the two attached foot pads. In one mode of operation the foot pads 32L, 32R are shown mounted to a double-leg platform frame 34. The foot pads may easily be attached and removed to the frame by sliding the track mechanism on the foot pads into the matching channels on the frame supports. Adding a fulcrum attachment is accomplished in the same manner by sliding a selected fulcrum attachment into the mounting device channel 36.
Referring now to FIG. 4B, a telescoping support for an adjustable double-leg platform as employed in one embodiment is schematically shown. In one embodiment the support bars 28 may advantageously comprise square telescoping tubing allowing adjustment of the distance between the foot pads. The telescoping tubing may comprise, for example, a telescoping assembly including a left member 28A, a central holding member 28C and a right member 28B. The telescoping members may included spring locks 31 that fit into a plurality of holes 29 arranged for different lengths. Such locking mechanisms are known in the art. A plurality of telescoping assemblies may be used in parallel as needed for support. The ends of the telescoping members are attached as above to the elongated support elements 42R, 42L. This feature allows adjusting the width of the stance as well as determining where the fulcrum is located relative to the foot pads. A therapist with a patient who is just starting to be weight bearing on an injured leg may want the center balance to be located closer to the patient's good leg as opposed to the injured leg.
Referring now to FIG. 5, an example of a storage rack as employed in one embodiment is schematically shown. The storage rack 26 includes a plurality of preferably modified mounting device channels 24 for holding the set of fulcrum attachments. The mounting device channels may be attached by conventional fasteners 46 or integrated within a back panel of the storage rack. Shown in more detail here is the set of hanging element 30, as for example a pair of evenly spaced hooks or equivalent devices may advantageously be attached to the frame 34 for conveniently hanging the platform and footpads when not in use.
Referring now to FIG. 6A, an alternate embodiment compression spring attachment with interchangeable springs and including a unidirectional stability ball as employed in one embodiment of the system is schematically shown. The compression spring attachment provides resistance to assist in strengthen specific areas of the ankle and lower extremities. This attachment is intended to be used in place of a fulcrum attachment and may be mounted to the frame or a foot pad by a mounting “T-track” 60 or the like as described herein. A top plate 48 supports the frame or foot pad. A unidirectional stability ball 50, as is known in the art, is centered between the top plate 48 and a bottom plate 54. The top and bottom plates are each partially hollowed in a rounded fashion in order to hold the ball in a central location between them. Springs 52 are attached between the top plate and the bottom plate to provide resistance and to hold the two plates together while in use. In one embodiment the springs may be fastened with removable fasteners, such as twist off fasteners, in order to allow the use of springs of varying resistance strengths.
Referring now to FIG. 6B, an alternate embodiment single platform compression spring attachment with interchangeable springs and including a unidirectional stability ball as employed in one embodiment of the system is schematically shown. In one embodiment the springs 52 may be fastened with removable fasteners, such as, for example, durable screws 53 in a metal insert, twist off fasteners or the like, in order to allow interchanging springs of varying resistance strengths as desired.
Referring now to FIG. 7, a set of fulcrum attachments for use in example embodiments is schematically shown. With a variety of attachments the system is able to be utilized at the skill level of the patient. As patients progress, and their skill level increases, the attachments can be changed to allow increased challenge to further aid skill development and patient progression. Under the supervision of a therapist or in a physical therapy setting the various attachments may be used for circumduction, plantar and dorsey flexion, eversion and inversion, and other therapy methods using different leg width positions to vary the level of difficulty.
Attachment 12 is generally rectangular in cross-section and may be used, for example, in the early stages of ankle rehabilitation. Attachment 14 is generally a trapezoidal shape and may have a smaller flat surface than attachment 12. Attachment 14 may be used for a patient in a more advanced stage of rehabilitation. Attachment 16 is a semi-oval shape and may be used in still further advanced stages of rehabilitation. Attachment 18 is substantially triangular in shape for use with patients having very improved mobility and balance skills. As shown in FIG. 1, one fulcrum attachment 22 includes a rounded cross beam for imparting a rocking motion to one or both ankles depending on whether it is mounted to a single foot pad or a double foot platform.
The set of fulcrum attachments 12, 14, 16, and 18 feature “T-track” mounting elements 62 for mounting to either a foot pad for single leg use or a double leg platform center support for double leg use.
Referring now to FIG. 8A, a cut-away side view of an alternate holding mechanism is schematically shown. Here the mounting channel in the support bars or other selected mounting elements are replaced by a locking channel 102 having a catch 103. The locking channel is slightly receded so as to allow the insertion of a push-button lock located on a fulcrum attachment or foot pad as the case may be. The locking mechanism includes a push button 110, a resistance spring 112 that applies an outward force to the push button 110. An arm 112 bears on a catch 104 which is biased by spring 106 and held by pivot arm 108.
Referring now to FIG. 8B the locking mechanism is further described. Here a fulcrum attachment 18 is shown with the locking mechanism mounted in place of a portion of the T-track.
Referring now to FIG. 9 a set of push-up handle attachments with integrated rail to attach to platform frame is shown. In one example the set of push-up handle attachments 910 may advantageously be made with a swivel mount indicated by arrows 912 that allow the handle to swivel 90 degrees or more to target different muscle groups. In another example, the push-up handle attachments 910 may be constructed to be rigidly mounted in any desirable orientation without the swivel mount. The swivel feature will allow the user to target different muscles groups, i.e. triceps vs. chest.
Having described the various features in this disclosure, it is now considered helpful to the understanding of this disclosure to explain the operation of at least one aspect of an example embodiment. In one aspect one, the pair of foot pads are mounted to the double-leg platform 34 and a fulcrum attachment is selected and mounted and locked in place to the central support element 41. A patient or other human subject may then stand on the foot pads to perform motion exercises. This should be done with the guidance of a professional therapist.
In another example, a fulcrum attachment is selected and mounted and locked in place to a single foot pad. A patient or other human subject may then stand on the foot pad to perform motion exercises using one leg. This should also be done with the guidance of a professional therapist.
The invention has been described herein in considerable detail in order to comply with the Patent Statutes and to provide those skilled in the art with the information needed to apply the novel principles of the present invention, and to construct and use such exemplary and specialized components as are required. However, it is to be understood that the invention may be carried out by specifically different equipment, and devices, and that various modifications, both as to the equipment details and operating procedures, may be accomplished without departing from the true spirit and scope of the present invention.
