Definitions
- the present invention relates to an insole for a shoe.
- the present invention relates to an insole device that can rehabilitate a foot by stimulating a proprioceptive reflex response in the wearer's foot.
- an arch rehabilitative catalyst stimulates the Golgi tendon organ, which in turn, stimulates the musculoskeletal structure of the foot to rehabilitate the foot structure.
- the catalyst is an asymmetrically domed hump, which creates a mild to strong discomfort to initially stimulate the Golgi tendon organ.
- the device disclosed in U.S. Pat. No. 5,404,659 does not function as described, and that the majority of users find the device too uncomfortable to use.
- the device when subjected to conventional vertical compressive forces of a person walking in the range of 2.5 times body weight, the device is designed to deflect between 40% and 60% of its maximum height, and when subject to only one times a person's weight, there should be no deflection.
- the device has an ideal apex height of 5.25% to 7.6% of the total foot length.
- a device built according to these dimensions and deflection capabilities results in an overly high arch height, and can cause severe discomfort, and possible injury, to a wearer.
- the absolute, non-weight bearing height of the device should be the same regardless of body weight and arch height. This is clearly wrong, since different wearers will have different comfort thresholds and arch heights.
- the device disclosed in U.S. Pat. No. 5,404,659 does not function as described. Users would find the device too hard to use successfully, and rather than stimulating a proprioceptive response, the device would cause pain and discomfort at each step. The pain engendered in the foot of a wearer would, in fact, cause the user to limit the pressure applied to the foot to avoid the discomfort, rather than exercising the foot by creating an imperceptible stimulation as is its stated goal.
- an arch rehabilitative catalyst stimulates the Golgi tendon organ, which in turn, stimulates the musculoskeletal structure of the foot to rehabilitate the foot structure.
- the catalyst is an asymmetrically domed structure having a said maximum height at it apex from 1% to 5% of the length of the foot.
- the catalyst does not provide a bracing function but instead, proprioceptive feedback.
- the plantar aspect of the catalyst has a receptacle for receiving an interchangeable insert. Many forms thereof, are disclosed.
- the catalyst is resiliently deformable to apply an upwardly directed pressure to stimulate the Golgi tendon organ, and deflects from between 40% and 100% of its maximum height in response to the vertical forces of a person standing at rest.
- the plantar aspect of the device is also characterized by a substantially domed shaped catalyst with a receptacle with vertical walls for removeably accommodating a resilient member with corresponding vertical walls.
- the plantar aspect of the devise is also characterized by a substantially domed shaped catalyst with a cavity or receptacle for removeably accommodating an insert which acts between the catalyst and an underlying surface to control the resilient deformability of the catalyst; and that the cavity and insert have an engagement means for resisting separation of the insert from the insole and lateral shifting therebetween.
- the devices disclosed in U.S. Pat. No. 5,404,659, in U.S. Pat. No. 6,301,807, and U.S. Pat. No. 6,732,457 incorporate dome shaped catalysts the positioning of which is fixed. This fixed positioning of the dome shaped catalysts restricts the stimulus to the center of the foot's arch apex to only those times when users of the devices are standing perfectly erect on perfectly horizontal terrain. In instances when the users are engaging in multidirectional bipedal activities during which their lower limbs are not perpendicular to the terrain whether the terrain is horizontal or not, users of the devices would experience stimulus to less than optimal locations around the periphery of the center of the arch apex as the foot moves about the dome shape. This less than optimal location of the stimulus to the sole of the foot results in a less than optimal proprioceptive reflex response and a less stable musculoskeletal arch system and ankle.
- the devices disclosed do not allow for any degree of adjustability in the relative positioning of the dome shaped catalyst to accommodate users who have feet of identical length but have variances in foot type. For example one person could have a longer arch and shorter toes and another have a shorter arch and longer toes, yet both could have the same foot length. In another example one person could have a wide foot and another a narrow foot, yet both could have the same foot length as the aforementioned persons. Therefore, the devices disclosed would fail to provide stimulus at the optimal location for one of the individuals.
- An insole device configured to fit the profile of the human foot to promote dynamic proprioceptive stimulation of the mechanoreceptors and nocioreceptors in the skin of the sole of the foot at the anatomical apex of the foot's arch system.
- the anatomical apex of the foot arch system being defined as the highest part of the mid-foot's boney structure when viewed from the mid-foot's medial to lateral aspect between the calcaneous (heel) and metatarsal heads (forefoot).
- the midfoot section of the insole device has a receptacle located central to the foot's anatomical arch apex that receives interchangeable resilient ellipsoidal and spherically shaped biofeedback catalysts of many shapes and forms.
- the resilient ellipsoidal and spherically shaped biofeedback catalysts present to the plantar aspect of the foot at a location found to be the anatomical apex of the foot's arch system.
- the resilient ellipsoidal and spherically shaped biofeedback catalysts display physical properties as to dynamically stimulate the body's natural neuromuscular reflex mechanisms that effectively optimally align and stabilize the foot's musculoskeletal arch system and ankle.
- the plantar aspect of the ellipsoidal and spherically shaped biofeedback catalysts encourages the catalysts to dynamically roll and pivot about their plantar apexes as they mirror the foot's movement through multidimensional activities. This dynamic movement ensures that the ellipsoidal and spherically shaped biofeedback catalysts' dorsal aspect apexes always optimally align with anatomical apex of the foot's arch system regardless of the angle at which the foot contacts the ground.
- the net result is a more structurally sound foot capable of optimally managing the forces generated during all bipedal activities with the most efficient use of muscular energy and the lowest degree of injury inducing stress.
- the stimulated neuromuscular activity results in the foot's musculoskeletal structure becoming progressively stronger and less susceptible to injury.
- the insole device provides rehabilitative, preventive, and performance enhancing benefits.
- the resilient ellipsoidal or spherical biofeedback catalysts display physical properties such that they do not provide functional bracing or support to the plantar aspect of the foot.
- the insole device has the ability to receive and interchange the resilient ellipsoidal or spherical biofeedback catalysts and the many forms thereof, as well as having provision to ensure proper placement of the catalysts relative to the user's anatomical arch apex.

Abstract
An insole device configured to fit the profile of a human foot to promote dynamic proprioceptive stimulation of the mechanoreceptors and nocioreceptors in the skin of the sole of the foot at the anatomical apex of the foot's arch system. The midfoot section of the insole device has a receptacle located central to the foot's anatomical arch apex that receives interchangeable resilient ellipsoidal and spherically shaped biofeedback catalysts of many shapes and forms. The resilient ellipsoidal and spherically shaped biofeedback catalysts present to the plantar aspect of the foot at a location found to be the anatomical apex of the foot's arch system.
Description
- This application claims the benefit of priority from U.S. provisional application no. U.S. 61/457,235 filed Feb. 9, 2011, the entire content of which is incorporated herein by reference.
- The present invention relates to an insole for a shoe. In particular, the present invention relates to an insole device that can rehabilitate a foot by stimulating a proprioceptive reflex response in the wearer's foot.
- Professionals dealing with gait related pathologies generally accept that a large majority of persons will, at some time in their lives, suffer some form of gait related pain or dysfunction. It is also well accepted that, in the majority of cases, the mechanism underlying the pathology, injury, or dysfunction is biomechanically related to the foot's musculoskeletal capabilities during the interface between the foot and the ground, during the initial contact, support, and propulsion phases of the gait cycle.
- It has been proposed that providing a device to create a proprioceptive, or internal, feedback stimulus to a user's foot can directly target the underlying pathology, injury, or dysfunction. Such devices are disclosed in U.S. Pat. No. 5,404,659 to Burke et al., in U.S. Pat. No. 6,301,807 to Gardiner, and in U.S. Pat. No. 6,732,457 to Gardiner.
- As disclosed in U.S. Pat. No. 5,404,659, an arch rehabilitative catalyst stimulates the Golgi tendon organ, which in turn, stimulates the musculoskeletal structure of the foot to rehabilitate the foot structure. The catalyst is an asymmetrically domed hump, which creates a mild to strong discomfort to initially stimulate the Golgi tendon organ.
- However, it has been found that the device disclosed in U.S. Pat. No. 5,404,659 does not function as described, and that the majority of users find the device too uncomfortable to use. In particular, when subjected to conventional vertical compressive forces of a person walking in the range of 2.5 times body weight, the device is designed to deflect between 40% and 60% of its maximum height, and when subject to only one times a person's weight, there should be no deflection. In addition, as disclosed in U.S. Pat. No. 5,504,659, the device has an ideal apex height of 5.25% to 7.6% of the total foot length. A device built according to these dimensions and deflection capabilities results in an overly high arch height, and can cause severe discomfort, and possible injury, to a wearer. It is further disclosed that the absolute, non-weight bearing height of the device should be the same regardless of body weight and arch height. This is clearly wrong, since different wearers will have different comfort thresholds and arch heights.
- In general, the device disclosed in U.S. Pat. No. 5,404,659 does not function as described. Users would find the device too hard to use successfully, and rather than stimulating a proprioceptive response, the device would cause pain and discomfort at each step. The pain engendered in the foot of a wearer would, in fact, cause the user to limit the pressure applied to the foot to avoid the discomfort, rather than exercising the foot by creating an imperceptible stimulation as is its stated goal.
- As disclosed in U.S. Pat. No. 6,301,807 and in U.S. Pat. No. 6,732,457, an arch rehabilitative catalyst stimulates the Golgi tendon organ, which in turn, stimulates the musculoskeletal structure of the foot to rehabilitate the foot structure. The catalyst is an asymmetrically domed structure having a said maximum height at it apex from 1% to 5% of the length of the foot. The catalyst does not provide a bracing function but instead, proprioceptive feedback. The plantar aspect of the catalyst has a receptacle for receiving an interchangeable insert. Many forms thereof, are disclosed. The catalyst is resiliently deformable to apply an upwardly directed pressure to stimulate the Golgi tendon organ, and deflects from between 40% and 100% of its maximum height in response to the vertical forces of a person standing at rest.
- As disclosed in U.S. Pat. No. 6,301,807, the plantar aspect of the device is also characterized by a substantially domed shaped catalyst with a receptacle with vertical walls for removeably accommodating a resilient member with corresponding vertical walls.
- As disclosed in U.S. Pat. No. 6,732,457, the plantar aspect of the devise is also characterized by a substantially domed shaped catalyst with a cavity or receptacle for removeably accommodating an insert which acts between the catalyst and an underlying surface to control the resilient deformability of the catalyst; and that the cavity and insert have an engagement means for resisting separation of the insert from the insole and lateral shifting therebetween.
- However, it has been found that the devices disclosed in U.S. Pat. No. 5,404,659, in U.S. Pat. No. 6,301,807, and U.S. Pat. No. 6,732,457 have a number of limitations that inhibit the devices' optimal positioning and the degree of stimulus provided to the plantar surface of the foot while the foot is interfacing with the ground, during the initial contact, support, and propulsion phases of the multidirectional bipedal activity gait cycles.
- In general the devices disclosed in U.S. Pat. No. 5,404,659, in U.S. Pat. No. 6,301,807, and U.S. Pat. No. 6,732,457 incorporate dome shaped catalysts the positioning of which is fixed. This fixed positioning of the dome shaped catalysts restricts the stimulus to the center of the foot's arch apex to only those times when users of the devices are standing perfectly erect on perfectly horizontal terrain. In instances when the users are engaging in multidirectional bipedal activities during which their lower limbs are not perpendicular to the terrain whether the terrain is horizontal or not, users of the devices would experience stimulus to less than optimal locations around the periphery of the center of the arch apex as the foot moves about the dome shape. This less than optimal location of the stimulus to the sole of the foot results in a less than optimal proprioceptive reflex response and a less stable musculoskeletal arch system and ankle.
- In addition, the devices disclosed do not allow for any degree of adjustability in the relative positioning of the dome shaped catalyst to accommodate users who have feet of identical length but have variances in foot type. For example one person could have a longer arch and shorter toes and another have a shorter arch and longer toes, yet both could have the same foot length. In another example one person could have a wide foot and another a narrow foot, yet both could have the same foot length as the aforementioned persons. Therefore, the devices disclosed would fail to provide stimulus at the optimal location for one of the individuals.
- An insole device configured to fit the profile of the human foot to promote dynamic proprioceptive stimulation of the mechanoreceptors and nocioreceptors in the skin of the sole of the foot at the anatomical apex of the foot's arch system. The anatomical apex of the foot arch system being defined as the highest part of the mid-foot's boney structure when viewed from the mid-foot's medial to lateral aspect between the calcaneous (heel) and metatarsal heads (forefoot).
- The midfoot section of the insole device has a receptacle located central to the foot's anatomical arch apex that receives interchangeable resilient ellipsoidal and spherically shaped biofeedback catalysts of many shapes and forms. The resilient ellipsoidal and spherically shaped biofeedback catalysts present to the plantar aspect of the foot at a location found to be the anatomical apex of the foot's arch system.
- The resilient ellipsoidal and spherically shaped biofeedback catalysts display physical properties as to dynamically stimulate the body's natural neuromuscular reflex mechanisms that effectively optimally align and stabilize the foot's musculoskeletal arch system and ankle. The plantar aspect of the ellipsoidal and spherically shaped biofeedback catalysts encourages the catalysts to dynamically roll and pivot about their plantar apexes as they mirror the foot's movement through multidimensional activities. This dynamic movement ensures that the ellipsoidal and spherically shaped biofeedback catalysts' dorsal aspect apexes always optimally align with anatomical apex of the foot's arch system regardless of the angle at which the foot contacts the ground.
- The net result is a more structurally sound foot capable of optimally managing the forces generated during all bipedal activities with the most efficient use of muscular energy and the lowest degree of injury inducing stress. With regular use, the stimulated neuromuscular activity results in the foot's musculoskeletal structure becoming progressively stronger and less susceptible to injury. The insole device provides rehabilitative, preventive, and performance enhancing benefits.
- The resilient ellipsoidal or spherical biofeedback catalysts display physical properties such that they do not provide functional bracing or support to the plantar aspect of the foot.
- The insole device has the ability to receive and interchange the resilient ellipsoidal or spherical biofeedback catalysts and the many forms thereof, as well as having provision to ensure proper placement of the catalysts relative to the user's anatomical arch apex.

reference 30 in the Figures. Theinsole device 30 consists of a flexible insole body having anouter portion 32 defining an upwardly opening hole orpassage 34 located central to the foot's anatomical arch apex. Thehole 34 receives interchangeable substantially ellipsoidal and spherically shapedcatalysts 40 for interfacing with the plantar aspect of a human foot. - The
catalysts 40 have an apex 42 on the dorsal surface for aligning with a target area within the foot, the target area being defined by the anatomical arch apex. - The plantar aspect (bottom) 44 of the catalysts, in concert with the flexible insole body encourage the catalysts to dynamically roll and pivot about their plantar apexes as they mirror the foot's movement through multidimensional activities.
- The
catalysts 40 are resiliently deformable to apply an upwardly directed pressure to stimulate the nocioreceptors and mechanoreceptors in the skin of the sole of the foot in response to downward pressure on the catalyst by the foot. The ellipsoidal and spherically shaped catalysts provide resilient deformability to allow the catalyst to deflect from between 10% and 100% of their maximum height in response to vertical forces of a person standing at rest being applied to the catalyst. - The catalysts' 40 resilient deformability may be selected so as to provide constant or variable resistance in response to vertical forces of a person standing at rest being applied to the catalyst. For example the catalyst may provide a constant or progressively increased or decreased compressive resistance relative to the degree of deformation.
- The
catalysts 40 may be of varied sizes and shapes relative to foot length and width and arch height. - The dorsal aspect (top) 43 of the
catalysts 40 may have varied radii or apexes at different locations relative to their horizontal midline to accommodate for a variety of foot types of the same foot length and ensure the optimal location of the stimulus provided. - The
dorsal aspect 43 of thecatalysts 40 may have varied radii or apexes at different locations relative to their frontal plane midline (50 inFIG. 10 ) to accommodate for a variety of foot types of the same foot length and ensure the optimal location of the stimulus provided. - The
plantar aspect 44 of thecatalysts 40 may have varied radii or apexes at different locations relative to their horizontal midline (50 inFIG. 10 ) to optimize the dynamic rolling and pivoting motion specific to requirements of different bipedal activities or pathologies. - The
plantar aspect 44 of thecatalysts 40 may have varied radii or apexes at different locations relative to their frontal plane midline to optimize the dynamic rolling and pivoting motion specific to requirements of different bipedal activities or pathologies. - The catalysts' 40 resilient deformability may be achieved by a variety of mechanical spring-like mechanisms or the use of resiliently deformable materials or a combination thereof.
- The
catalysts 40 may be comprised of a variety of materials, densities, and resiliencies such as foams, rubbers, plastics, or other flexible materials. The catalysts may be comprised of one piece made from one material or comprised of a number of pieces made from different materials.Catalysts 40 comprised of a number of pieces may be preassembled as one unit or may be comprised of a number of interchangeable interlocking pieces that can be assembled by the user. The catalysts may be hollow and pressurized to varying degrees with gas, for example air or nitrogen. -
FIG. 29 illustrates a variety of one piece designs for thecatalyst 40 wherein a first density/resiliency material 150 is overmoulded onto a second density/resiliency material 152 having a higher or lower density/resiliency. - The
flexible insole body 30 may be comprised from a variety of materials such as foams, rubbers, and plastics as well as synthetic and natural fabrics. Theinsole body 30 may be comprised of one piece made from one material or may be comprised of a number of pieces made from different materials. Insole bodies made of a number of pieces may be preassembled as one unit or may be comprised of a number of interchangeable interlocking pieces that can be assembled by the user. The catalysts may also incorporate a mechanical spring (spiral or leaf) comprised of metal or a metal alloy. - The flexible insole body and
catalysts 40 may have a variety of co-operating engagement means for securing interchangable ellipsoidal and spherically shaped catalysts to the insole body. The co-operating engagement means may include detent means for resisting separation of the ellipsoidal and spherically shaped catalysts from the insole body and may allow or restrict shifting therebetween. - The detent means may include a groove or channel or
indent 70 around the long axis circumference of the shaped catalysts. See for exampleFIGS. 1-20 , 26 and 30-38. The inner circumference of said channel or indent would correspond to the circumference of thehole 34 in theinsole body 32 to receive theedge 35 of thehole 34. An insole body with ahole 34 of a larger circumference relative to the circumference of the channel in the catalysts would provide a co-operating engagement means for securing the catalysts to theinsole body 32 and allow thecatalysts 40 to move or adjust slightly within theinsole body 32 while still resisting separation. An insole body with a hole of an equal circumference relative to the circumference of the channel orindent 70 incatalysts 40 would provide a co-operating engagement means for securing thecatalysts 40 to the insole body and allow for less movement or adjustment within the insole body. - Another cooperating engagement means for securing
interchangeable catalysts 40 to theinsole body 32 may include flexible orelastic tethers 80 that extend from the catalysts having an enlarged end at their distal ends. The enlarged ends would fit into corresponding cavities or smaller holes in the insole body thereby securing the tether's larger ends into the insole body and securely suspending the catalysts in the center of the hole in the insole body. - Another co-operating engagement means for securing
interchangable catalysts 40 to the insole body may include a flexible or elastic anchor ortether 80 that is affixed to theinsole body 32 so as to bisect the long axis center of thehole 34 in theinsole body 32. As shown inFIG. 25 , thecatalyst 40 would incorporate aslit 82 along the long axis from one side through to alarger channel 84 at the center of the catalyst's long axis. Thelarger channel 84 at the center of the catalyst's long axis would correspond in size and shape to the size and shape of thetether 80. The shape of thetether 80 and correspondingchannel 84 in thecatalyst 40 would be such as to permit or restrict the long axis movement of thecatalyst 40 along thetether 80 while insuring that thecatalyst 40 remains secured to thetether 80. Alternatively, as illustrated inFIG. 23 , theslit 82 may open into acylindrical passage 83 which received thetether 80. Longitudinal movement of thecatalyst 40 to thetether 80 in this case is limited bystops 85 fore and aft thecatalyst 40. - As illustrated in
FIG. 24 , another co-operating engagement means for securing interchangeable ellipsoidal and spherically shapedcatalysts 40 to theinsole body 32 may include a flexible orelastic tether 80 that is affixed to theinsole body 32 as to bisect the long axis center of thehole 34 in the insole body. Thecatalysts 40 would be comprised of opposing top and bottom pieces with one of thepieces protrusion 94 extending from the center of its base; theprotrusion 94 being larger at its distal end. The opposingpiece tether 80 would provide for apositioning hole 86 at its center, the shape of thehole 86 corresponding to the cross sectional shape of the protrusion. Thecatalyst 40 would be secured to theinsole body 32 by inserting theprotrusion 94 through thehole 86 in thetether 80 then inserting theprotrusion 94 in thecavity 96 of the opposing piece in such a manner as to interlock the opposingpieces protrusion 94 may be a separate component or “plug” as illustrated inFIG. 27 . - Another co-operating engagement means for securing interchangeable ellipsoidal and spherically shaped
catalysts 40 incorporating a channel orindent 70 around their long axis circumference to theinsole body 32, may include a flexible orelastic tether 80 that is affixed to theinsole body 32 as to bisect the long axis center of thehole 34 in theinsole body 32. Thetether 80 would incorporate an elastic ring 88 at its center; the shape of the ring 88 matching the corresponding shape of the catalyst's long axis circumference; the hole in the ring 88 being smaller in circumference than the channel orindent 70 around the long axis circumference of the ellipsoidal and spherically shapedcatalysts 40. When the ring 88 in thetether 80 is stretched to fit into the channel orindent 70 in thecatalyst 40, the resulting tension of the ring 88 on thecatalyst 40 ensures that thecatalyst 40 remains secured to thetether 80. -
FIGS. 30 through 36 show another embodiment of the present invention as illustrated inFIGS. 30 through 36 which differs from the above described embodiments namely in the internal configuration of thecatalyst 40. As best seen inFIGS. 33 , 34 and 35, thecatalyst 40 has a plurality of cavities extending inwardly from a bottom face thereof The illustration shows a honeycomb-like configuration, however the cavities could have round, rectangular, oval, square, hexagonal, octagonal, polygonal, etc. cross-sectional shapes, or even a combination thereof The cavities could all be of similar size and wall thickness or consist of varying sizes and wall thicknesses. Furthermore the side walls defining the cavities could be substantially parallel or alternatively, have varying degrees of draft or even be bulged. The catalyst could be made from a variety of materials such as foams, rubbers, silicones, plastics, etc. as a one piece or multi-piece part in one or a combination of materials. For example, the top could be a clear plastic and the “honeycomb” could be a thermal plastic rubber, that is either overmoulded or attached with an adhesive. - By varying the materials and the above geometrical features, one is able to vary the compression, rebound, and dynamic movement characteristics to accommodate progressive level of resiliencies in a variety of different applications/needs (foot types, body weight, pathologies, activities).
- Although the “honeycomb” arrangement is shown having a
groove 70 extending thereabout for mounting within thehole 30 within the insole body, it could be adapted to a flexible or elastic tether arrangement of the sort described previously. -
FIGS. 39 through 50 show a variety of alternate embodiments of a catalyst according to the present invention. According to theFIGS. 39 through 41 embodiment, thecatalyst 40 has resilient plastic like top andbottom caps bottom caps ring 114 which may be of plastic or steel that offers resiliently. Thering 114 may or may not be filled with afoam 116 in its core. Thering 114 with or without thefoam 116 acts as a mechanical spring. - In the
FIGS. 42 through 44 embodiment, thecatalyst 40 comprises resilient plastic or moulded foam top andbottom caps foam core 124. - In the
FIGS. 45 through 47 embodiment, thecatalyst 40 has resilient plastic-like or moulded foam top andbottom caps cut foam ring 136 which may extend around afoam core 138 having a different foam density than thefoam ring 136. - In the
FIGS. 48 through 50 embodiment, thecatalyst 40 has resilient plastic-like or moulded foam top andbottom caps cut foam ring 146 surrounding a gas or air-filledcore 148. - The foregoing description of the preferred embodiments and examples of the apparatus and process of the invention have been presented to illustrate the principles of the invention and not to limit the invention to the particular embodiments illustrated. It is intended that the scope of the invention be defined by all of the embodiments encompassed within the claims and/or their equivalents.
