Definitions

  • the present invention relates generally to orthotics and more particularly to a bi-layer orthotic and a tri-layer orthotic configured to absorb energy and then return it to an individual wearer's foot.
  • Walking and running can be defined as methods of locomotion involving the use of the two legs, alternately, to provide both support and propulsion, with at least one foot being in contact with the ground at all times. While the terms gait and walking are often used interchangeably, the word gait refers to the manner or style of walking, rather than the actual walking process. The gait cycle is the time interval between the exact same repetitive events of walking.
  • the defined cycle can start at any moment, but it typically begins when one foot contacts the ground and ends when that foot contacts the ground again. If it starts with the right foot contacting the ground, then the cycle ends when the right foot makes contact again.
  • each cycle begins at initial contact with a stance phase and proceeds through a swing phase until the cycle ends with the limb's next initial contact.
  • Stance phase accounts for approximately 60 percent, and swing phase for approximately 40 percent, of a single gait cycle.
  • Functional orthotic inserts may be placed in a shoe either on top of or in place of the insole to correct foot alignment and side-to-side movement during standing, walking, running to influence the orientation of the bones in a human foot and to influence the direction and force of motion of the foot or parts of the foot. Orthotics thereby decrease pain, not only in the foot, but also in other parts of the body such as the knee, hip and lower back. They can also increase stability in an unstable joint and prevent a deformed foot from developing additional problems.
  • conventional devices are not dynamic as designed.
  • Conventional orthotic devices typically include a shimmed, rigid post and as a result dynamic adjustments to the foot during the gait cycle cannot be done. For example, adjustments such as making the foot tip out further, making the foot tip in further, raising the heel, raising the ball of the foot, and the like cannot be accomplished with conventional devices dynamically during the gait cycle.
  • Diabetes is a chronic disease that affects up to six percent of the population in the U.S. and is associated with progressive disease of the microvasculature. Complications from diabetes include not only heart disease, stroke, high blood pressure, diabetic retinopathy but also in particular diabetic neuropathic foot disease.
  • Patho-mechanical foot dysfunctions include supination and pronation pathologies.
  • FIG. 1 illustrates a foot (in phantom lines) at rest wearing the energy return system 10 in accordance with the invention.
  • the energy return system 10 is shown in the unburdened or off-loaded position with the base layer 12 at rest on a surface such as the ground.
  • the energy return system 10 broadly includes base layer 12, lever 14, platen 16 and orthotic 18.
  • Base 12 may be of any length so long as it generally extends from the sole of the foot to the toe region.
  • Base 12 may comprise any material used for the soles of shoes including but not limited to rubber, plastics, polymers, polyurethanes and the like.
  • the gait cycle begins when one foot contacts the ground and ends when that foot contacts the ground again. Thus, each cycle begins at initial contact with a stance phase and proceeds through a swing phase until the cycle ends with the limb's next initial contact.
  • Stance phase is the part of the cycle when the primary foot is in contact with the ground and begins with initial contact or heel strike and ends with toe-off.
  • Swing phase occurs when the opposite, second foot is in the air and begins with toe-off and ends with the second heel strike.
  • the loading response begins with initial contact, the instant the primary foot contacts the ground.
  • the heel of the primary foot contacts the ground first (unless the patient has equines as depicted in alternative embodiment in FIGS. 56 ).
  • the downward force (DF) of the heel causes base layer 12 to deform upwardly toward the heel as noted by arrow U.
  • Angled central portion 24 of lever 14 commences to compress downwardly 37 toward slide 22 as angled connecting portion rotates distally RB toward angled central portion 14 causing the buildup of tension on tensioning member 28.
  • angled connecting portion 26 is operably coupled to orthotic 18 by tensioning member 28 the tensioning of tensioning member causes the orthotic to deform downwardly.
  • the orthotic can be segmented at the front portion (as best seen in alternative embodiment depicted in FIG. 31 ).
  • the tensioning member may be manipulated to deform the orthotic at a particular location/segment or in a particular angulation.
  • the arch can be raised to supinate the foot.
  • the foot can be pronated by drawing up the lateral side of the orthotic thus being able to dynamically generate a supination or pronation moment or force while the person is walking.
  • the tensioning member 28 would drive the orthotic 18 down and flatten it.
  • the attachment point of the tensioning member 28 to the orthotic 18 was towards the front of the orthotic 18 the tensioning member 28 would draw the orthotic 18 back and raise the arch.
  • the ball of the foot is drawn down into a position closer to contact on the platen, i.e. the plane of support, causing the arch of the foot to carry weight bearing pressure and not the ball of the foot during mid-stance (as seen best in FIG. 13 ).
  • FIG. 3 it depicts further compression of the energy return system.
  • the arch of the foot is seen as compressed downwardly even further (than in FIG. 2 ) and thus more energy is being stored in the orthotic 18.
  • pathology exists in the forefoot, by way of example an ulcer or a stress fracture or a metatarsal non-union, when the orthotic 18 is once again allowed to elevate, it creates an upward moment or force behind the ball of the foot that will lift and unload the ball as the person is moving toward forefoot loading in which the ball of the foot sustains a great deal of pressure. The lift created right behind the ball of the foot will unload or unweight.
  • FIGS. 1-5 depict a basic energy return system.
  • a lever operably coupled at the front of the orthotic and a lever operably coupled to a back portion of the orthotic have been described.
  • the orthotic layer also deforms. How it deforms, i.e. in which direction and at what angulation, depends primarily in part on the point of attachment of lever 14 as will now be discussed in detail.
  • FIG. 6 various attachment points on tensioning member 28 and resulting actions are depicted. If the attachment point of the tensioning member 28 to the orthotic 18 is varied, such variation will cause the orthotic 18 to flex in different ways to affect the foot. With a rear attachment of tensioning member 28 to orthotic, the arch of the orthotic 18 is lowered thus reducing ground reactive force between the foot and the orthotic that in the case of posterior tibial dysfunction may make the orthotic intolerable to the patient. This dynamic lowering of ground reactive forces at impact may allow greater biomechanical control to be tolerated by the patient. If the attachment point of the tensioning member 14 to the orthotic 18 is at the front of the orthotic 18, the orthotic arch is raised as best seen in FIG. 13 .
  • the subtalar joint occurs at the meeting point of the talus and the calcaneus.
  • the subtalar joint allows inversion and eversion of the foot during the gait cycle.
  • the attachment point of the tensioning member would affect the function of the energy return system. If the attachment point of the tensioning member is placed lateral to the subtalar joint access toward the fifth ray or the lateral aspect of the forefoot, it would have the effect of raising the lateral arch of the orthotic to pronate the foot or tip the foot inward and cause eversion of the subtalar joint.
  • Attachment of the tensioning member medial to the subtalar joint access would have the effect of raising the medial aspect of the orthotic and would have the effect of causing supination and tip the foot laterally which would invert the subtalar joint.
  • Attachment of the tensioning member to the arch portion of the orthotic would draw the orthotic arch height down to be more flat. This would allow for rebound recoil spring as the lever is unweighted in the back. Drawing the orthotic layer down to the platen and allowing it to rebound back up as the lever is unweighted in the back would create lift proximal to the metatarsal heads or underneath the metatarsal heads if the orthotic is lengthened.
  • the orthotic could be altered in length to affect changes in the foot anatomy.
  • Conventional orthotics terminate behind the ball of the foot to allow for flexion of the ball of the foot.
  • the orthotic could be lengthened to be positioned underneath the ball of the foot if unweighting was desired at that area.
  • the orthotic is positioned underneath the metatarsal heads and supported the metatarsal head weight a thrust upward under the ball of the foot could be created increasing vertical energy (as in a jump).
  • the orthotic could also be windowed under an area of an ulcer such that it prevented loading on the ulcer.
  • the flexibility in the base layer 12 and the rocker bottom shape would allow normal gait while controlling dorsiflexion and plantar flexion of the metatarsal phalangeal joint during gait. As noted, flexion of the base layer 12 provides flex energy while also providing shock absorption.
  • attachment point of the tensioning member to the orthotic and platen can be varied depending of the type of pathology that is being treated and the length and position of the orthotic may also be changed to affect changes in foot anatomy, the foregoing causing the orthotic to act as a leaf spring.
  • FIGS. 7-10 illustrate a first alternative embodiment of the energy return system 700 in accordance with the invention comprising base layer 712, lever 714, platen 716 and orthotic 718.
  • the energy return system 700 of FIGS. 7-10 performs as does the energy return system 10 of FIGS. 1-6 .
  • the energy return system 700 illustrated in FIG. 7 is shown at the initial contact with the ground and is incorporated into footwear, brace or the like shown in phantom line. Arrow depicts the normal downward force DF of the foot and the energy return system 700 against a surface at grade.
  • Base 712 may be of any length so long as it generally extends from the sole of the foot to the toe region and may comprise any material used for the soles of shoes including but not limited to rubber, plastics, polymers, polyurethanes and the like. Base 712 is desirably resilient and functions as a leaf spring in this alternative embodiment.
  • Lever 714 includes slide 722, angled central portion 724, fulcrum 725, terminal portion 726 and cable 728.
  • Lever 714 is made from a material that is resilient to allow it to dynamically deform during the gait cycle. Suitable materials that may be utilized for lever 714 include plastics, polymers and resilient metals.
  • Orthotic 718 is also made from a material that is resilient to allow it to dynamically deform during the gait cycle.

Platen 716 is desirably made from rigid or semi-rigid materials such as plastics know to those of skill in the art.

  • Fulcrum 713 lies adjacent and supports platen 716.
  • Terminal portion 726 includes loop 727 that operably couples cable 728 through pass 729 in platen 716.

  • Cable 728 is depicted as a cable or wire but may also comprise pins, rods, filaments and other structures known to those of skill in the art.
  • the downward force (DF) of the heel causes base 712 to deform upwardly DU 850 toward platen 716.
  • Slide 722 moves backwards toward heel putting tension on cable 728. Cable 728 thus pulls orthotic 718 away from the ball of the foot 752 causing it to rise against arch 754.
  • FIG. 9 the foot is shown as commencing forward rotational motion of the foot 952 toward mid-stance. Downward forces on the heel are released and unloaded 956. This rebound causes lever 714 to move toward its original position 958, 960 releasing energy from orthotic 718 and causing orthotic to flatten against the arch 962 and to thrust forward and upward 964.
  • FIG. 10 illustrates the foot continuing its normal forward rotational motion toward toe-off 954 with energy unloaded from the energy return system.
  • FIGS. 11-14 illustrate a second alternative embodiment of the energy return system in accordance with the invention similar to FIGS. 7-10 except cable 1128 is shown operably coupled to orthotic 1118 immediately proximal to the ball of the foot.
