DETAILED DESCRIPTION

[0140] FIG. 1 shows a mat 2 of one embodiment of the present invention. The mat 2 may be the same size and shape of as a common yoga matabout 72 to 80 inches long, by about 24 inches wide, and about 0.25 inches thick. The mat length must be long enough to allow a patient to complete one gait cycle, i.e. a double step. One of ordinary skill the art will appreciate that longer mats allow more than one gait cycle also contemplated by this disclosure. The mat 2 includes loop strips 6 positioned along the length of the mat, about every 6 inches, that targets and provides visual reference so steps can be analyzed. The loop strips 6 also selectively receive targets placed at preferred locations. One of ordinary skill the art will appreciate that the targets may be selectively interconnected to the mat by other methods, such as by magnets, snaps, clasps, or other selectively interconnecting mechanisms. Although the loop strips are shown orthogonal to the mat's lateral edges 10 and parallel to the mat's first edge 14 and second edge 18, they could be angled relative to the lateral edges 10. Further, a loop strip grid may be provided.

[0141] The mat also includes a measurement tool 20 printed or fixed along at least one of the first edge 14, the second edge 18, or one of the lateral edges 10. The measurement tool allows stance position measurement and helps locate the targets. The mat may include measurement indicia on at least two orthogonal mat sides to allow step length and width distance assessment.

[0142] FIG. 2 shows a mat 22 that may be shorter than the floor showing FIG. 1. Here, the mat 22 is designed to be attached to a door or wall via selective interconnection mechanisms, grommets, straps, or any other device that allows the mat 22 to hang vertically. In this fashion the mat 22 can be positioned at various heights. Further, the mat 22 is hung so the measurement device is vertical or horizontal. Lines 26, which can be loop strips, with high contrast with different spatial frequencies will assist with optokinetic stimulation.

[0143] FIGS. 3-9 show examples of how targets 44 can be placed in various configurations for stepping and balance training. Here, the targets 44 are footprint shaped. One of ordinary skill in the art will appreciate that the targets 44 may be of any shape, such as circles as shown in FIG. 14. The targets 44 may be of the same texture or each adjacent target 44 may be of different textures. Any combination of textures is contemplated. For example, two adjacent targets may have the same texture wherein the third target has a different texture and so forth. It follows that the targets may have different heights, be comprised a different foams and materials, etc. As described above, targets 44 that produce auditory cues may also be used to provide gait mechanics or heel to toe feedback.

[0144] FIG. 9 shows a plurality of targets 44 of varied thicknesses positioned on a mat 2 of one embodiment of the present invention. The targets 44 may be made of a combination of resilient material, such as foam, and stiff materials. The therapist may provide a treatment protocol that requires the patient to step on targets of various thicknesses so they can learn to ascertain surface height changes from a target to another.

[0145] FIGS. 10-12 show a footprint shaped target 44 of one embodiment of the present invention. Here, a foam base 48 that is about 0.75 inches thick is employed that has at least two locations 52inserts, recesses, pouches, etc.for the receipt of clickers or other sound-producing mechanisms. The heel insert may be in the shape of a teardrop and the forefoot insert may be an oval shape so the clicker can be turned facing towards the top or bottom of the footprint to accommodate the patient's foot for easier clicker activation. The target may be constructed of the foam base layer 48 and a foam upper layer 56, which may be textured. The sound-producing elements 60 are provided in the recesses 52 in the base layer. The base member includes a selectively interconnecting member, such as hook/loop fasteners that selectively receive and retain corresponding interconnection mechanisms on the upper layer 56.

[0146] FIGS. 13-13D show a target 44 with various textures it can incorporate. The target 44 may be substantially flat wherein no texture is employed. Alternatively, and often beneficial to rehabilitation, the target 44 may be covered, or covered in selected areas, with a textured surface. Furthermore, a target may include various textures to define different areas of the target, the boundaries of the target, etc.

[0147] For example, detailed views 13A-C show some textures contemplated by embodiments the present invention. Those of ordinary skill the art will appreciate various other textures may be employed without departing from the scope of the invention. The location of the ends of the leader lines associated with FIGS. 13A-13C are not meant to indicate the exact location of the textured area. FIG. 13A is composed of pyramid shapes formed in lightweight EVA (ethylene vinyl acetate) foam. In one embodiment, the pyramid peaks are spaced about 2.5 mm apart and are about 3 mm high.

[0148] FIG. 13B shows a texture composed of crisscrossed, raised portions, which may be formed of small, soft fingers. FIG. 13C shows a turf-like texture made of polyethylene fibers (denier 10,800/4,500, pile height: tufted at 1.75-inch stabilized duel layer primary backing, secondary backing: 20 oz. HD urethane coating).

[0149] The textures contemplated herein may be made of recycled rubber materials. And, as mentioned above, the textured upper target portions may include a selectively interconnection mechanism, such as hook and loop fasteners (i.e., Velcro) that allow the upper portion to be selectively interconnected to base layers comprising a foam or other material. The foam used by some embodiments of the present invention possess an indentation force deflection (IFD) of about 95, which equates to a density of 1.8 pounds per cubic foot (PCF). The base portion may be molded or include a corresponding selective interconnection system, i.e. the hook of a hook and loop fastener system. By contrast, the upper layer may have an IFD of about 61 with the density of 2.5 PCF. In practice, the top, textured layer of the target may be positioned on the mat alone, or in combination with the foam base layer.

[0150] FIG. 13D shows a side elevation view of the top, textured target layer of one embodiment of the present invention. Here, the top layer is about 0.375-inch-thick, wherein the apex of the textured surface is supported by a sub-base interconnected to the base layer of the target or directly to the mat.

[0151] The textured surface and the control mat surface may emulate textures found in an accompanying children's book. The book will include, for example, illustrations of how animals and humans balance and move and corresponding exercises. Animal sounds may be the auditory cue so the child or mentally-impaired patient may match the sound with the texture. A child must feel the texture in the book then note the same on the floor or wall mat.

[0152] FIG. 14 is yet another top plan view of the mat 2 of one embodiment of the present invention employed circle-shaped targets 44 instead of footprint shaped targets. One purpose of this figure is to illustrate that targets 44 may be of any shape without departing from the scope of the invention. Here, the targets 44 are spaced in such a way to help train individuals to master or improve reaching their hand to target to improve balance during reaching tasks.

[0153] While various embodiments of the present invention have been described in detail, it is apparent that modifications and alterations of those embodiments will occur to those skilled in the art. It is to be expressly understood that such modifications and alterations are within the scope and spirit of the present invention, as set forth in the following claims. Further, it is to be understood that the invention(s) described herein is not limited in its application to the details of construction and the arrangement of components set forth in the preceding description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of including, comprising, or having and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items.
