Description

THERAPY SHOE
Technical Field The present disclosure generally relates to systems and methods for providing medical therapy and specifically to systems and methods for assisting the stimulation of blood flow, reducing edema, reducing leg cramping, treating plantar fasciitis in the foot, and/or promoting recovery from athletic excursion. More specifically, the present disclosure generally relates to a shoe configured to hold a removable and/or integrated device that applies pressure to a wearer's foot to treat various ailments and/or provide athletic recovery after physical exercise.
Background In order to enhance circulation in a person's body, particularly in the feet and legs, periodic or cyclic compression of tissue, such as plexus regions of the foot, at predetermined timed intervals is beneficial. Under normal circumstances, blood moves up the legs due to muscle contraction and general movement of the feet or legs, such as when walking. If a person is immobilized, unable to move regularly, or has poor circulation brought on by disease, the natural blood return mechanism is impaired, and circulatory problems such as ulcers and deep vein thrombosis can occur.
To mitigate these problems, it is desirable to concentrate a compression force against veins throughout the legs and/or feet. Current systems are primarily based on pneumatic compression devices that squeeze the entire foot, calf, or thigh. These systems require significant power, and are inefficient because they provide high levels of force across the entire foot or leg rather than focusing in on those areas with the highest concentration of blood vessels. In addition, these systems may include air bags that can rupture at the seam, especially with high pressure within the bag.
In various current devices, tethered air lines limit mobility, and can lead to injury should the person attempt to walk while the device is in use. Further, existing devices may not be suited for continuous usage. Users cannot walk with them, or move away from the compression unit. The device must be removed before a user can walk.
Additionally, current devices lack the ability to track and report user usage and compliance. Also, most pneumatic devices are quite noisy and can cause irritation of the skin leading to ulcers.
Furthermore, current devices do not blend in well with ordinary clothing and stand out as medical devices. It would be advantageous to provide a therapy shoe that could be worn as ordinary clothing and not be an obvious medical aid.

Summary In an exemplary embodiment, an item of footwear comprises a housing, a therapy device disposed within a cavity in the housing, and a coupling portion. The coupling portion is configured to retain a portion of a foot.
In another exemplary embodiment, a method for compressing a foot comprises providing an item of footwear having a therapy device entirely contained therein, coupling the item of footwear to the foot, and activating the therapy device.
In another exemplary embodiment, an athletic shoe comprises a housing configured with an aperture having a flexible aperture cover. The athletic shoe further comprises a foot compression system disposed within the housing. The foot compression system comprises a pressure pad extendable to at least partially displace the flexible aperture cover into contact with the venous plexus region of a foot. The housing is configured with an opening on an external side of the housing. The opening allows access to a control component of the foot compression system.
In another exemplary embodiment, an item of footwear comprises a housing having an aperture therethrough. The aperture is configured with a flexible aperture cover. The item of footwear further comprises a sole, and a therapy device disposed between the housing and the sole. The therapy device is configured to extend at least partially through the aperture to compress a portion of a foot. The item is footwear is configured to fully conceal the presence of the therapy device when the item of footwear is worn.
The contents of this summary section are provided only as a simplified introduction to the disclosure, and are not intended to be used to limit the scope of the appended claims.

In various exemplary embodiments, therapy shoe 100 is configured to be one of shaped to receive a right foot, shaped to receive a left foot, or shaped to receive a right or left foot. In certain exemplary embodiments, therapy shoe 100 may be provided in pairs, for example two therapy shoes 100, one each for the right foot and the left foot.
With reference now to FIG. 4, in accordance with an exemplary embodiment, a user (and/or caregiver, third person, etc.) may insert therapy device 400 into a cavity of therapy shoe 100 (not shown). Straps 160, 163, 165 (from a first closed position) of therapy shoe 100 are opened. A portion of a user, such as a lower extremity (e.g. foot), is inserted between a first and second side of straps 160, 163, 165, and comes into contact with surface 120. The location of the portion of a user with respect to surface 120 and/or other components of therapy shoe 120 may be a function of the location of therapy shoe 100's elements and/or a user's individualized anatomy. Once a portion of a user is in a desired position, straps 160, 163, 165 may be adjusted and/or closed (e.g., from a second position to a first closed position). Therapy device 400 may be activated through opening 110.
In various exemplary embodiments, therapy shoe 100 is configured to withstand force provided by a user while therapy shoe 100 is coupled to the user. For instance, a user may provide a force to therapy shoe 100 by standing or walking while coupled to therapy shoe 100. A user may move at any pace while coupled to therapy shoe 100. It will be appreciated that, in certain embodiments, therapy shoe 100 is configured to allow a user to remain mobile; however, in other exemplary embodiments, therapy shoe 100 is configured for use by a user who remains non-ambulatory while coupled to therapy shoe 100.
For example, in certain exemplary embodiments therapy shoe 100 is configured as a "walking" shoe. In these embodiments, therapy shoe 100 may be utilized by a wearer in a manner similar to a conventional shoe. In these embodiments, therapy device 400 may be configured to be inactive when the wearer is walking, for example in order to prevent wearer discomfort, damage to therapy device 400, and/or the like. In other exemplary embodiments, therapy show 100 is configured as a "non-walking" shoe. In these embodiments, therapy shoe 100 may be utilized by a wearer when non-ambulatory.
In these embodiments, therapy device 400 may be configured to be constantly active, active at a scheduled interval, and/or the like.
With reference now to FIG. 6, in various exemplary embodiments therapy shoe may be coupled to and/or utilized in connection with a compression garment, for example compression sock 680. Compression sock 680 may be configured to work in a complementary manner with therapy device 400, for example in order to treat and/or prevent deep vein thrombosis, to facilitate athletic recovery, and/or the like. In an exemplary embodiment, compression sock 680 is releasably coupled to therapy shoe 100 via one or more of zippers, snaps, straps, buttons, hooks, hook and loop fasteners, and/or the like. In other exemplary embodiments, compression sock 680 is permanently coupled to therapy shoe 100, for example via gluing, stitching, and/or the like.

Compression sock 680 may comprise any suitable flexible material and may be configured with any suitable dimensions, shapes, curves, stitching, and/or the like, as desired, in order to at least partially receive and/or compress a portion of a limb. Moreover, compression sock 680 may be configured with any suitable level of compression, for example from between about 5 mmHg to about 50 mmHg. Compression sock 680 may be configured as knee-high, as thigh-high, as pantyhose, and/or in any other suitable configuration.
Because compression sock 680, when wom by a user, compresses the surface veins, arteries, muscles, and other soft tissue, circulating blood is forced through narrower circulatory channels, increasing the arterial pressure. This distribution of blood in the limb of a wearer can facilitate improved results (for example, increased blood circulation, decreased pooling of blood in the feet and lower extremities, etc.) responsive to operation of therapy device 400. Stated another way, when compression sock 680 and therapy device 400 work in tandem, blood flow is further concentrated and increased, with the result of facilitating athletic recovery, reducing deep vein thrombosis, reducing edema, and/or the like.
