Orthotic arch support device and method for use

Description

TECHNICAL FIELD

[0001] The present disclosure relates generally to the podiatric, orthopedic, orthotic and footwear fields related to providing arch support for the foot. More specifically, but not exclusively, the present disclosure relates to devices and methods for providing continuous contact with the plantar surface of the foot during all phases of the gait cycle.BACKGROUND OF THE INVENTION

[0002] Most solutions for providing arch support are either rigid and provide a structured system without foot flexibility or flexible and unable to provide plantar support. Device that are rigid and / or uniform are adept to stationary activities, such as, standing, but do not provide support when the user is active as they remain linear to the plantar aspect of the foot. Flexible or softer insole devices allow for increased flexibility, but do not provide sufficient plantar and arch support. Thus, new and improved arch support devices and methods for using the devices are needed to provide both foot and sole flexibility while also providing increased plantar and arch support.

[0003] US 3,339,555 (Rotko) describes an adjustable arch support device comprising a pair of superposed panels secured together to form a side opening pocket. WO 97 / 41747 (Bio Racing B.V.B.A) describes an arch support provided with means to enable its shape to be adjusted in accordance with the desired support for the arch and a sale which is provided with such a support. JPH 10127305 (Tsunakawa Fukuji) describes a foot sole supporting material and footwear for supporting loaded body weight by an arch.SUMMARY OF THE INVENTION

[0004] The present disclosure is directed toward an orthotic for providing continuous contact with the plantar surface of the foot during all phases of the gait cycle.

[0005] According to the claimed invention, an orthotic is provided, comprising: a base member; an arch support portion; and a covering coupling the arch support portion to the base member; and wherein the arch support portion comprises: a plurality of arch members surrounded by the covering and spaced apart from the base member; each arch member of the plurality of arch members comprises: a top portion; a bottom portion opposite the top portion; a first end; a second end opposite the first end; a medial side coupled to the top portion on one end and the bottom portion on another end; and a lateral side coupled to the top portion on one end and the bottom portion on another end; and characterized in that an opening extends from the first to the second end.

[0011] Referring to the drawings, wherein like reference numerals are used to indicate like or analogous components throughout the several views, and with particular reference to FIGS. 1-7, there is illustrated an exemplary embodiment of an orthotic device or arch support 100. The orthotic device 100 includes a base member 110, an arch support portion 130, and a covering 150 to moveably couple the arch support portion 130 to the base member 110.

[0012] With continued reference to FIGS. 1-7, the base member 110 includes a top or superior side 112 opposite a bottom or inferior side 114, a first or distal end 116 opposite a second or proximal end 118, and a medial side 120 opposite a lateral side 122. The base member 110 may also include a recessed region 126 extending into the base member 110 from the medial side 120. The distance between the recessed region 126 on the medial side 120 and the lateral side 122 may vary to position the arch support portion 130 in the desired location for a given patient and / or a given anatomical pathology. For example, the distance between the recessed region 126 and the lateral side 122 of the base member 110 may be wider or narrower than shown. The base member 110 may be made of, for example, a soft rubber, flexible silicone, or a like material that provides support and flexibility to the plantar side of the foot. The inferior side 114 of the base member 110 may include, for example, a plurality of members (not shown) or a textured surface (not shown). The plurality of members may be, for example, a plurality of hexagonal or polygonal members that allow the base member 110 to deform and return to shape during a wearer's gait cycle. The plurality of members may also be positioned in a lattice matrix (not shown). The superior side 112 of the base member 110 may be, for example, generally flat with contours that match the shape of the foot of the wearer or alternatively, may be, for example, preformed to address anatomical pathologies of the wearer.

[0013] The arch support portion 130 includes a plurality of arch members 132, as shown in FIGS. 1-5. Each arch member 132 of the plurality of arch members 132 includes, for example, a top or superior portion 134, a bottom or inferior portion 136, a first or distal end 138, a second or proximal end 140, a medial side 142, and a lateral side 144, as shown in FIGS. 1 and 2A. The superior portion 134 of the arch members 132 may be, for example, arced or curved between the medial side 142 and the lateral side 144 of the arch members 132. The superior portion 134 of the arch members 132 may be, for example, arced or curved in a convex orientation, a concave orientation, or a combination of convex and concave orientations between the medial side 142 and the lateral side 144. The lateral side 144 may also be, for example, arced or curved as it extends between the superior portion 134 and the inferior portion 136 of the arch members 132. The inferior portion 136 may be, for example, relatively planar or flat as it extends between the medial side 120 and the lateral side 122. The medial side 142 may also be, for example, relatively planar or flat as it extends between the superior portion 134 and the inferior portion 136 of the arch members 132. In addition, at least one first arch member 132 may be, for example, tapered in a distal to proximal direction between the first and second ends 138, 140 of the arch member 132, and at least one second arch member 132 may be, for example, tapered in a proximal to distal direction between the first and second ends 138, 140. In an embodiment, the center arch member 132 may be, for example, planar or flat in a proximal-distal direction, i.e. may not be tapered. Although shown as an odd number of arch members 132, i.e., five arch members 132, the arch support portion 130 may have, for example, any number of arch members 132, which may be an odd or even number of arch members 132, as needed to provide continuous contact with the plantar surface of the foot with any given anatomical pathology.

[0014] Each arch member 132 includes an opening or hollow portion 146 extending from the first or distal end 138 to the second or proximal end 140 of each arch member 132. The size and shape of the hollow portion 146 may be selected, for example, to provide the desired support and flexibility for a patient's plantar arch through the entire gait cycle. The edges of the hollow portion 146 of each arch member 132 may form, for example, a rimmed edge around the perimeter of each arch member 132 on the first and second ends 138, 140. The rimmed edge of the arch members 132 may be, for example, rounded, curved, smooth or the like to allow for each arch member 132 to translate with respect to the adjacent arch members 132. The plurality of arch members 132 may be, for example, collated or positioned relative to each other to form the shape of the arch of the foot. The plurality of arch members 132 may, for example, align in a resting state, as shown in FIGS. 1-7, to form the arch support portion 130 of the orthotic device 100. Alternatively, the arch members 132 may be, for example, offset such that they are positioned in a non-linear planar orientation, as needed to provide continuous contact with the plantar surface of the wearer's foot. In addition, the planes of each arch member 132 may be, for example, positioned generally perpendicular to the recessed region 126 of the base member 110, or alternatively, the planes of each arch member 132 may be, for example, positioned at varying angles relative to the recessed region 126 of the base member 110. The position of the planes of each arch member 132 relative to the recessed region 126 of the base member 110 may be selected to provide continuous contact with the plantar surface of the wearer's foot for a given anatomical pathology. The arch support portion 130 may be, for example, semi-flexible. The arch members 132 may be, for example, made of slices of plastic or a like material that provide the desired support for the arch of a patient's foot and also the desired flexibility to move during the gait cycle.

[0015] As shown in FIGS. 1-3, the lateral side 144 of each arch member 132 is positioned adjacent to the medial side 120 of the base member 110 in a recessed region 126. The arch members 132 may, for example, directly contact at least a portion of the medial side 120 of the base member 110 or be spaced apart from the base member 110. The arch members 132 may also be positioned to correspond to the position of a patient's foot arch when the plantar side of the foot contacts the base member 110. The arch members 132 may also be positioned, for example, at the most lateral portion of the arch. The arch members 132 may be, for example, coupled to or secured to the base member 110 by a covering 150, such as an elastic covering or deformable covering 150. The covering 150 may be secured to the base member 110 by, for example, coupling or sealing the covering 150 to a rim (not shown) of the base member 110. The covering 150 may be, for example, sealed into a rubber rim on the medial side or edge 120 of the base member 110 and the rim may be inset into the base member 110. The covering 150 surrounds or encases the arch members 130 to retain order and shape of the arch support portion 130. The covering 150 also allows for the arch members 132 to form the arch support portion 130 of the orthotic device 100 and also to move with respect to the other arch members 132. In addition, the covering 150 may allow for the arch members 132 to overlap with the adjacent arch members 132 as the shape of the foot arch changes during a person's gait cycle. The covering 150 may be made of, for example, an elastic fabric material or another material that stretches and is flexible.

[0016] A method, which is not part of the claimed invention, of using the orthotic device 100 is also disclosed. The method includes the plurality of arch members 132 aligning to provide consistent segmental pressure to the arch, primarily, the plantar fascia, during the flat foot and mid stance phase of the gait cycle. Next, during the heel off and toe off phases of the gait cycle, the plurality of arch members 132 slide past the neighboring or adjacent arch members 132 based on the flexion of the foot and the shape change of the sole providing contiguous pressure to the arch / plantar fascia. Then, during the mid-swing stance phase of the gait cycle, the plurality of arch members 132 remain in an overlapped arrangement to provide equal segmental pressure to the arch / plantar fascia. Next, during the heel strike phase of the gait cycle, the individual arch members 132 again slide past neighboring or adjacent arch members 132 corresponding to the change in shape of the sole providing contiguous pressure on the arch / plantar fascia. Finally, during the flat foot and mid stance phase of the gait cycle, the plurality of arch members 132 realign to allow the plurality of arch members 132 to repeat the movement cycle.

[0017] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprise" (and any form of comprise, such as "comprises" and "comprising"), "have" (and any form of have, such as "has", and "having"), "include" (and any form of include, such as "includes" and "including"), and "contain" (and any form of contain, such as "contains" and "containing") are open-ended linking verbs. As a result, a method or device that "comprises," "has," "includes," or "contains" one or more steps or elements possesses those one or more steps or elements, but is not limited to possessing only those one or more steps or elements.
