Prosthetics foot | PPT

2. &#; Over the past decade, options in prosthetic feet have expanded to more than 50 different models. Today, amputees have a wide array of feet to choose from, designed for walking, dancing, cycling, golfing, swimming, snow skiing and running. &#; Heavier wood and steel materials have been replaced by lightweight plastics, aerospace alloys and carbon-fiber composites. &#; Much like the human foot , many of to day&#;s prosthetic feet can store and return some of the energy generated during walking.

3. &#; Provide a base for the weight bearing. &#; Shock absorption and controlled plantarflexion in loading response. &#; Accomodation to uneven terrain and controlled advancement of the prosthetic shank during midstance. &#; Heel rise and weight transfer during terminal stance. &#; Transmission through double support and preparation for the swing phase. Ref:- Michelle M. Lucardi, Orthotics and prosthetics in rehabilitaion, 2nd edition, 422.
4. Three main functions of human foot and ankle:- &#; shock absorption, &#; Weight-bearing stability, and &#; Progression/limb advancement. &#; Ref:- Perry J. Gait Analysis; Normal and pathological function. New York, Mcgraw-Hill,, 11-16
5. &#; The Prosthetic foot duplicates each biomechanical motion with a mechanical substitute. &#; This biomechanical motion dependent on the position of the components of the foot as well as their motion and structure. &#; An individual with an amputation has no physical connection between the musculature of the residual limb and prosthetic foot, so prosthetic foot must substitute the bony anatomy as well as loss of muscle action. Ref:- Michelle M. Lucardi, Orthotics and prosthetics in rehabilitaion, 2nd edition, 422.
6. &#; Important component of loading response. &#; While the foot plays an important role, the entire limb contributes to shock absorption. &#; Stance phase knee flexion follows ankle plantarflexion. &#; Eccentric dorsiflexor muscle action provides muscular shock absorption during ankle motion. &#; The anatomical structure of the foot contributes to shock absorption through tarsal mobility and various joint articulations. &#; The series of lower limb joint motions transforms the lower limb and specifically the foot and ankle complex into a loose packed structure that accepts weight bearing and provides shock absorption. Ref:- Human Foot and Ankle Versus Prosthetic Foot/Ankle Mechanism Function
7. &#; Weightbearing Stability is essential as the contralateral limb leaves the ground. &#; Advancement of the loading force vector from the hindfoot to the forefoot places an increasingly greater demand on intertarsal and metatarsal alignment to alter the foot and ankle complex from a loose packed and flexible structure to close packed and rigid structure. &#; Meanwhile, the medial longitudinal arch remains effective at absorbing energy and adapting to uneven surfaces and variable ground reaction forces.
8. &#; After midstance, a series of alignment changes occur between the hip, knee and tibia that reverse from internal rotation to external rotation. &#; The hindfoot and midfoot tarsals and forefoot metatarsals and phalanges gradually transform the foot to a rigid lever structure capable of transferring loading, providing stability and assisting in propulsion in late stance phase. &#; Locking of the subtalar joint. &#; From midstance to late stance and upon heel rise, tension creates upon the plantar fascia to effectively shorten its length. &#; &#;Windlass effect&#; transform the transverse tarsal joint into a closed packed position. &#; The closed packed position creates a rigid lever system capable of transferring loading across the foot at the push off phase of gait.
9. &#; The foot moves into the forefoot rocker from terminal stance to pre-swing. Although the forefoot remains in contact with the ground, the body is progressing through contralateral swing in preparation for ipsilateral swing. &#; At the end of stance phase, forefoot dorsiflexion reaches a peak, maximizing the windlass effect.
10. 1. Shock absorption:- &#; Prosthetic components emulate shock absorption But have far fewer mechanisms to do so. &#; They lack sufficient triplanar rotary motion or variable loading stability. &#; It emulate the the shock absorption by two ways A. Recreating the first rocker, B. Attempt a completely different shock absorption approach
11. A. Recreating the first rocker:- &#; The single axis foot uses a hinge to recreate sagittal plantarflexion and dorsiflexion. &#; Shock absorption occurs through the dissipation of energy in the plantarflexion bumper. &#; Material properties of the bumper affect the amount of energy dissipation
12. B. Trying something different: &#; The cushion heel of the SACH design provides shock absorption. &#; ESAR designs provides shock absorption through material compression. &#; Deformation of the cushion heel of the SACH foot design and several other types of feet under loading allows shock absorption in the absence of simulated ankle plantarflexion. Material compression
13. &#; Prosthetic foot/ankle mechanism requires softness at initial stance and the stiffness required at terminal stance. &#; A prosthetic foot/ankle mechanism with flexible keel and forefoot will encounter knee instability due to deformation of the prosthetic forefoot during terminal stance. &#; One disadvantage in foot/ankle mechanism designs with a cushion type heel is the prolonged "heel-only" contact. This produces an unstable external knee flexion moment until the forefoot makes contact. &#; EMG studies reveal prolonged co-contraction of hamstrings and quadriceps muscle groups to maintain stability. &#; Knee instability associated with prolonged loading upon the heel may also result in more falls when persons with limb loss walk on low-friction surfaces such as wet tile or ice.
14. &#; Progressive stiffness is directly influenced by the composition and geometry of the forefoot keel. &#; Composition may consist of multi-carbon plates, a urethane "sandwich," or a carbon footplate. &#; The geometry may be the cross-sectional taper and angle or curve of the keel as well as the surrounding material provide spring stiffness.. &#; A wide blade width accommodates a wide variety of center of pressure (COP) pathways, but may decrease efficiency overall. Geometry of keel Composition of keel
15. &#; Categories of the prosthetic foot are based on the combination of functional tasks that they are designed to simulate. &#; Classification:- 1. Nonarticulating feet 2. Articulating design (Single axis, multi-axial feet) 3. Prosthetic feet with elastic keel 4. Dyanamic response or energy storing feet
16. &#; SACH FEET:- &#; It is available since . &#; Todays SACH foot differs very little in Principle from those in early design. &#; It has no true moving parts or articulations. &#; Relies on the flexibility of its structure for Joint motion simulation. &#; Parts:- Keel:- Firm keel surrounded by dense yet Flexible foam to give shape to the foot. Heel:- A cushion wedge is placed under the keel in the posterior of the foot. Belting:- Rubberised belting is attached to the distal area of the keel and extends to the end of the toes.
17. &#; This belting simulates to flexors and assist in giving a slight resistance to MP extension during preswing, thus preventing a feeling of dropping off of the toe during this phase of gait. &#; Types:- 1. SACH Foot with External keel 2. SACH Foot with Internal keel INTERNAL KEEL EXTERNAL KEEL
18. &#; Jaipur Foot is an improved version of a conventional SACH (Solid Ankle Cushion Heel) foot rather to say a dynamic foot with shorter/flexible keel. &#; It is basically a soft multi axial foot, meaning that it is flexible along multiple axes. &#; The greatest advantage of Jaipur foot over SACH foot is that it allows all natural movement of the foot including Dorsiflexion movement and looks like a natural foot. &#; It provides enough dorsiflexion to permit an amputee to squat.
20. SACH Foot &#;Wooden Keel is long enough to restrict/limit movements in all direction and what so ever movements take place they occur at unnatural sites. &#;.Squatting is not possible with SACH foot as it requires dorsiflexion at ankle joint, which due to its rigid keel is not possible. &#;.No cross- leg sitting is possible because it requires adduction at forefoot & transverse rotation of foot in relation to shank. &#;.As there is almost no movement at sub- tarsal joint inversion or eversion is not possible; so SACH Foot is suitable only for walking on level ground walking on uneven grounds & rough terrain is very uncomfortable. &#;.Bare-Foot walking is not possible. Jaipur foot &#;Metallic keel (carriage bolt) is confined to ankle only. So no restriction of movement and all the movements take place at natural sites. &#;.Squatting is easily achieved; as a sufficient range of dorsiflexion is attainable comfortably. &#; .Cross- legged sitting is possible because sufficient forefoot adduction & transverse rotation of foot in relation to shank is available. &#;.As there is adequate inversion & eversion at subtarsal level, so walking on uneven ground and rough terrain is very comfortable. &#; .Bare-Foot walking is possible.
21. &#; At initial contact and loading response:- &#; Cushioned heel provides for shock absorption. &#; Compression of the heel cushion simulates the The action of the lost pre-tibial muscle group . &#; Compression also allows controlled progression into The early stance phase. &#; In transtibial amputee it provide early stance Stability by limiting rapid knee flexion during Loading response. &#; Soft heel cushion can be chosen for a stable foot flat position very quickly. Ref:- Michelle M. Lucardi, Orthotics and prosthetics in rehabilitaion, 2nd edition,
22. &#; Midstance:- &#; SACH foot has no true inversion and eversion motion to accommodate uneven terrain. &#; The rubber structure may aid in, but i.e very negligient amount. &#; Simulation of the ankle rocker is controlled through the keel of the foot. &#; The rigid keel offers resistance to tibial advancement until the weight line is past the toe break of the foot.
23. &#; Terminal stance:- &#; Heel rise during toe rocker and progression are function of the length of the keel. &#; Some SACH foot use various keel lengths or densities but mostly use keel length corresponds to length of the foot. &#; In late stance .the prosthetic foot stable and resists rapid heel rise until the weight line passes the toe break, where the keel ends. &#; When weight line reached at the end of the keel toe dorsiflexion begins. &#; If keel is too short, early heel rise and rapid knee flexion occurs. &#; If keel is too long, heel rise and knee extension moment delayed. &#; Toe break simulates dorsiflexion. &#; Toe dorsiflexion is controlled by belting, so the tibial progression smoothly. &#; Dorsiflexed toe offer little weight bearing support. &#; It also depends on alignment with socket and foot,. &#; Flexibility of the belting material adds a small elastic motin to help in knee flexion as the prosthetic foot moves towards the preswing phase.
24. &#; Indication:- Prosthetic users at the level of household and limited community ambulation. &#; Contraindication:- In high level activities and sports or if the user must traverse uneven terrain.
25. &#; Advantages:- 1. Extreme durable. 2. Requires very little maintenance throughout the life of the foot. 3. It has wide variety of heel heights. 4. Excellent shock absorption characteristic. 5. Often recommended for use in temporary or preparatory prosthesis. 6. Light wt. 7. Low cost. &#; Disadvantages:- 1. Inherent lack of flexibility. 2. Inability to accommodate uneven terrain. 3. Proper alignment is very difficult because of lack of movable artculations. 4. Its design and construction allows optimal performance during relaxed walking cadence and in a single alignment configuraton.
27. &#; Sten foot:- Stored energy foot &#; Dual articulated wooden keel. &#; Tarsometarsal & metatarsophalangeal keel articulation Provide smoother roll over. &#; cushioned heel provide shock absorption. &#; Externally it uses kinsgley foot mold & rubber. &#; Heavier than SACH foot. &#; Expensive than SACH foot. &#; In higher level amputee knee buckle occurs. Rubber plugs
28. &#; Single &#;Axis foot:- &#; It simulated a ankle joint that actually Permits motion about the plane of the joint Axis. &#; This design was the first true articulating Foot. &#; Direct descendant of the historic conventional Wooden foot. Structure:- 1. Keel with a molded rubber foot shell. 2. Ankle articulation &#; made of steel, with replaceable plastic bushing. 3. Toes:- reinforced with flexible belting , attached to the keel to give a degree of stiffness, while still retaining flexibilty. 4. Plantar flexion bumper:- compression of the rubber bumper allows upto 15 degree plantarflexion. 5. Dorsiflexion bumper:- compression of the anterior bumper allows 5-7 degrees of dorsiflexion.
29. At Initial contact & loading response:- &#; Shock absorption occurs due to combined compression of the rubber heel & plantar flexion bumper. &#; when Heel reaches full compression , the force is transferred To the plantarflexion bumper. &#; Plantarflexion bumper begins to compress and absorb shock of ground. &#; Control the descent of the foot. &#; Bumper can be of varying durometers or firmness. &#; Denser the rubber bumper more resistance to plantarflexion and a knee flexion moment create. &#; In soft heel bumper, foot reaches in flat position quickly. &#; Ref:- Michelle M. Lucardi, Orthotics and prosthetics in rehabilitaion, 2nd edition,
30. &#; At midstance:- &#; Articulation allows only sagittal plane motion. &#; Accomodation to uneven terrain. &#; No true coronal plane movement. &#; Inversion/eversion motion is due to inherent flexibility within the rubber portion of the foot and toes. &#; Combination of the dorsiflexion bumper and solid keel controls the advancement of the prosthesis tibial shank during midstance. &#; After full dorsiflexion movement keel acts as a rocker to continue the tibial shank progression.
31. &#; At Terminal stance & preswing: &#; Heel rise is determined by dorsiflexion bumper or stop. &#; Force is transferred to the foot, heel rise is intiated once the bumper is fully engaged. &#; The length of the keel in the foot also contributes to the control of heel rise. &#; Once the end point of ankle dorsiflexion is reached, the distal portion of the keel acts as a rocker. &#; When the force is transferred to the end of the keel, toe dorsiflexion begins. &#; At the initiation of the preswing functions is same as SACH foot.
32. &#; Indications:- &#; Transtibial amputee with adequate knee extensors. &#; Nonremrdiable strength impairment &#; Short residual limb. &#; Transfemoral amputee with good hip extensors. &#; Contraindication:- &#; Patient with poor aerobic capacity. &#; Strength impairment.
33. &#; Advantages:- 1. Able to reach a stable foot &#;flat position quickly in the early stance. This advantageous for activities that have an impact on knee stability. 2. Reduces the need for strong knee extension in loading response. 3. Reduces the knee flexion moment during loading response. 4. Capability of changing the durometers of the bumper to suit the needs and activity level of the users. &#; Disadvantages:- 1. Increased wt. 2. Needs maintenance. 3. Increased energy demand. 4. occasional service for normal wear and tear. 5. Bushing in the joint needs to be replaced. 6. With repeated loading bumper can fatigue over time.
34. &#; This foot operates in a similar manner to the single-axis foot, using various combinations of rubber bumpers. &#; Allows coronal, transverse and sagittal motion. &#; Stability is found at only at the extremes of each plane of motion. &#; These foot/ankle mechanisms can be a simple split-keel variety, a carbon plate urethane overmolded sandwich, a hindfoot articulation or a combination of these designs. &#; Available in variety of styles. 1. The Greissinger foot (Ottobock industries) 2. Multiflex ankle-foot(Endolite America)
35. &#; Widespread use in Europe and limited But steady success in US. &#; Features:- &#; Wooden keel- sorrounded by a molded Rubber foot. &#; Wooden ankle interface- connected to the keel of the foot by a U bolt & yoke assembly. Allow inv/evrsion and rotation. &#; Rubber bumper &#; between ankle bolt & U bolt &#; Plantarflexion bumper- posteriorly , &#; Dorsiflexion bumper- anteriorly. &#; need of maintenance of the rubber & plastic parts &#; Heavy in wt.
36. &#; Has fewer moving parts, needs reduced maintenance. &#; Structure:- 1. Ball & stem assembly:- provide resistance to plantarflexion. 2. Snubber:- provide resistance to dorsiflexion. 3. internal Keel Ball & stem assembly Snubber
37. &#; At initial contact & loading response:- &#; Shock absorption is provided by the compression rubber ball & stem. &#; During shock absorption compression O ring occurs between ankle & foot. &#; As weight is applied compression of the rubber ball provide controlled progression to midstance. &#; Plantar flexion resistance can be adjusted by changing the bumper or O ring.
38. &#; At Midstance:- &#; Multiaxial foot accomodates to uneven terrain in all the 3 planes. &#; True inversion/eversion is allowed by compression of the rubber rocker insert. &#; As this foot allows transverse rotation, it allows to abosrb the rotational forces. &#; Tibial advancement is controlled by the stiffness of the rubber components of the ankle. &#; Once Full compression of the rubber components is reached, force is transferred to the foot. &#; The length of the keel determines the continued amount of resistance during terminal stance.
39. &#; At Terminal stance:- &#; Heel rise is controlled by keel length & rubber components. &#; At the end of the dorsiflexion, distal portion of the keel acts as rocker. &#; At heel rises the foot pivots over the edge of the keel, &#; Toe dorsiflexion is controlled by the construction of the toe area. &#; Toe break is present at the end of the keel, &#; Belting is attached at the end of the keel to provide elasticity. &#; Preswing phase this elasticity and inner supporting structure provise spring action. Toe rocker
40. &#; Indications:- 1. Those with mechanical instability of their anatomical knee 2. Poor postural control. 3. Vulnerable skin or fixed adhesion along the incision line of residual limb &#; Contraindications:- 1. Muscle weakness 2. An individual unwilling to schedule regular maintenance.
41. &#; Advantages:- 1. Accommodate uneven terrain in more than one plane. 2. Useful for reducing torque forces on the residual limb during stance. 3. The density of the rubber bumpers can be changed for accomodation to user&#;s weight & activity level. &#; Disadvantage:- 1. Motion is allowed in all 3 planes, provides less static stability. 2. Muscle weakness people may not feel stable. 3. Heavier than non-articulating, elastic keel or dyanamic response foot. 4. Needs regular maintenance for moving parts. 5. Bushing and bumpers may wear and tear with use.
42. &#; The elastic keel foot is designed to mimic the Movement characteristic of human foot without use of the true articulation. &#; Such a task requires the design attention to be placed Primarily on the keel of the foot and the material surrounding the foot shell. &#; The elastic keel foot mimics the windlass effect of Plantar fascia. &#; Several version of this type of foot is available. &#; SAFE II foot is a classical example of elastic keel Foot.
43. &#; SAFE II FOOT:- &#; Solid attachment flexible endoskeleton foot. Structure:- 1. Cushioned heel 2. Keel- two parts 3. Short plantar band 4. Long plantar band 5. Toe break Heel Proximal keel Distal keel Plantar band Toe break
44. &#; At initial contact & loading response:- &#; Heel cushion and relative movement of the rigid block within the foot shell provides shock absorption. &#; In some foot keel flexibility also provides shock absorption. o At midstance;- o The differences in this feet become apparent during the transitions from early stance through midstance to terminal stance. &#; Inversion/eversion is simulted by flexilbility of the elastic keel. &#; Accomodation to terrain occurs between keel & its sorrounding dtructure. &#; Tibial advancement is controlled by the plantar band. &#; As the tibia advances, the keel begins to bend & foot start to dorsiflex. &#; The plantar band begins to tighten, controlling the rate that the keel bends. &#; Other foot this occurs due to flexible keel. &#; Most elastic keel feet have limited ability of rotation. &#; Rotation occurs due to movement of flexible keel within the rubber housing.
45. o Terminal stance:- &#; Heel rise is controlled by the stiffness of the keel. &#; Tibial advancement occur and weight transferred onto forefoot. &#; Keel extends all the way into the toe area. &#; No rocker effect. &#; Elastic keel feet eliminates the need for a rocker effect and provide a smoother roll- over. &#; SAFE II foot has additional control during dorsiflexion & heel rise as tension is applied to plantar bands. &#; Bands allows gradual stiffening of the forefoot to create a semirigid lever during terminal stance. &#; Other foot rely on flexibility of keel. &#; Elastic keel compressed. &#; In preswing a sense of energy returns is there. &#; Ref:- Michelle M. Lucardi, Orthotics and prosthetics in rehabilitaion, 2nd edition,
46. &#; Indications:- &#; Individual with a moderate need for accomodation to uneven terrain. &#; Alternative for the prosthetics user who would benefit from the multiaxial foot but does not want the maintenance or weight characteristic. &#; Contraindications:- o Extremely active patient who prefer a stiffer keel. &#; Advantages:- 1. Provide a very smooth gait pattern. 2. Stair climbing or descent and incline negotiation is easy. 3. Range of motion and torque absorption is possible. &#; Disadvantages:- Spongy feel may be disliked for those who needs greater sense of stability.
47. &#; Options for high-performances prosthetic user. &#; Most prosthetic foot designed to substitute normal foot-ankle motion. &#; Many foot are unable to meet increased performances demand on running & jumping. &#; Prosthetic foot with energy storing capabilities absorbs and store forces during loading and release this forces during push-off.
48. &#; Seattle foot:- &#; First commercially available energy storing foot. &#; Structure:- &#; One-piece keel of synthetic material embedded in a foam foot shape. &#; The keel provides a unique combination of stiffness & flexibility to absorb force. &#; Cadence increases, time spent on the forefoot increases. &#; During terminal stance keel compresses, absorbs more & more energy. &#; As foot is unloaded in preswing, the stored energy released and aid in progression.
49. &#; Carbon copy II Foot:- Energy storing foot Structure:- &#; keel- composed two strong deflection plate, made out of carbon graphite plate &#; the longer deflection plate terminate at the distal Ip joint. &#; shorter upper plate activated under high load. &#; Plates are available in 3 levels of resistance. &#; Provide little mediolateral stability.
50. &#; Quantum foot:- &#; Nonarticulated foot. &#; Keel is in the form of spring module. &#; Consists of two deflection plate attached to the Ankle base. &#; Keel projects forward towards metatarsophalangeal Joint & backward at heel. &#; Simulated plantarflexion & impact absorption is Provided by the heel deflection plate. &#; Lower plate stores & returns energy during last half&#; of the stance phase. &#; Upper plate acts as a spring in case of high forces. &#; Spring module encased in semiflexible cosmetic shell Which yields to medial & lateral loads. Upper deflection plate lower deflection plate
51. &#; Flex walk foot:- &#; Made out of carbon graphite composite. &#; Keel extends upto MT joint line and constitute a heel That substitute cushion heel. &#; Heel portion comes in two varieties. Low and high Heeled shoe. &#; It resists torsion. &#; Provide little inversion and eversion movement. &#; Encased in a plastic foam cosmetic cover.
52. &#; Flex foot:- &#; Distal part is same as flex walk foot. &#; Keel extends from MT joint line to the bottom of the socket or to the knee units for AK amputee. &#; Keel forms the shank of the prosthesis. Shank acts as a long leaf spring, stored more energy than Other foot. &#; Lighter than any other foot ankle complex. &#; It requires sufficient space between residuam and floor.
53. &#; Indications:- 1. High demand activities . 2. When maximum late stance dorsiflexion is desired. 3. When frequent changes in cadence or velocity is necessary or when walking on inclines. 4. Long arc of dorsiflexion protect the sound limb against execessive vertical force. &#; Contraindication:- Amputee with relaxed gait and household ambulation. &#; Advantages:- 1. Most user able to walk with less difficulty and more energy efficiency over a range of grades & speeds. 2. Wide variety of stiffness available acc. To the need of the patient. &#; Disadvantages:- 1. Designed to deform under loading condition, if not sufficient force is there, it become very stiff and unaccomodating. 2. Cost is high.
54. &#; At initial contact & loading response:- &#; Shock absorption during early stance is comparable to the other classes. &#; Cushion heel compresses to absorb the shock. &#; Control of plantarflexion is also affected by the stiffness in the heel. o At midstnace:- &#; Do not have significant ground accomodation &#; Stiff elastic keel feet. &#; Rubber and foam shell minimal accomdation of terrain. &#; No true inversion/eversion . &#; In split toe allows some degree of coronal plane motion. o At terminal stance:- &#; Significant difference in tibial advancement. &#; As cadence increases to running , extra stiffness is required during midstance into terminal stance. &#; Tibial advancement is controlled by stiffness of keel. &#; The shaft advances, keel deflects, absorbs forces generated during deflection and resists rapid advancement.
55. o Progression of heel rise is related to stiffness of the keel. o As the shaft continues to advance, the keel continues to deflect and the foot dorsiflexes as weight progresses onto the forefoot. o The keel extended upto distal end of the foot. o No rocker action. o Extended keel provide necessary support. o In high loading activity progression onto the forefoot occurs through a smooth arc of dorsiflexion as the keel continues to deform under the increasing load throughout this phase. o Keel deflection and dorsiflexion are now at their maximum points. o Stiff yet flexible keel has allowed maximal dorsiflexion without sacrificing support to the amputated side, the runner is allowed a longer stride length. o As unloaded keel begins to decomoress to return to its original shape, creating a spring action.
56. &#; Indication:- 1. When late stance dorsiflexion is desired. 2. When frequent changes in cadence or velocity is necessary. 3. When walking on inclines. &#; Contraindication:- &#; For users unable to generate enough forces to deform. &#; Advantages:- Walk with less difficulty and more energy efficiency over a range grades and speeds. &#; Disadvantages:- &#; Cost is high. &#; Stiff if enough forces is not applied.
57. &#; Hybridizing the properties of different classes, primarily by combining dynamic response feet with multi-axis attributes. &#; The traditional classification system has become outdated . &#; Proposed subsets could include: 1. Forefoot Keel 2. Heel Lever 3. Hindfoot Roller 4. Flexing Strut 5. Forefoot Inversion/Eversion 6. Multiaxis Hindfoot 7. Integrated Shock
58. 1. Forefoot keel:- &#; The Forefoot Keel is characteristic of the most basic ESAR foot/ankle mechanism with any number of materials and configurations. &#; The Forefoot Keel can be a single-bladed member or consist of multiple separate members. &#; Stiffness is directly dependent on the cross section, material, keel length, and geometry. &#; Some designs use multiple layers that collapse progressively,. &#; others use a urethane sandwich, which has a smoothing effect on the load progression
59. &#; 2. Heel Lever:- &#; The Heel Lever emulates the heel rocker, which contributes to load acceptance and ankle plantarflexion characteristics. &#; Many foot/ankle mechanisms simply use a cushion heel that simulates plantarflexion by compression. &#; such as the Flex-Foot Mod III, a heel lever projects posteriorly from the forefoot keel or midfoot attachment, and often provides stiffer support than a cushion heel. &#; Recent designs have used multiple levers, linkages, urethane bumpers or a urethane sandwich to simulate the progressive stiffness of the anatomical foot and ankle
60. &#; 3 Hindfoot Roller:- &#; A Hindfoot Roller mechanism used by many foot/ankle mechanisms uses a rocker element mounted on a footplate to approximate the ankle rocker from loading response to midstance. &#; This mechanism emphasizes the rotary motion of the ankle rocker to ease the transition from loading response. &#; When configured as a complete circular mechanism that wraps superiorly, the Hindfoot Roller can also function indirectly in shock absorption by emulating midtarsal dorsiflexion. Excessive rocker function in late midstance would be nonphysiologic, leading to a loss of support in late stance.
61. &#; 4. Flexing Strut:- &#; A Flexing Strut proximal socket attachment originated with the Flex-Foot design. &#; Incorporate the forefoot keel in one integrated structure. &#; The strut is usually a wide rectangular cross section. &#; Using continuous fibers in the strut composition insures maximum flexibility and strength. &#; All these Flexing Strut designs offer the greatest amount of energy return. &#; The longer the continuous fibers are in the lay-up of the composite, the greater the amount of bending flexion that can occur.
62. &#; 5. Forefoot Inversion-Eversion:- &#; Forefoot Inversion-Eversion split-toe design. &#; Other designs are more integrated, molding different durometer materials or members together within the foot so there are not necessarily articulating parts. &#; Some designs create a forefoot composite urethane sandwich. &#; The damping characteristics of the forefoot may limit the desired energy return,.
63. &#; 6. Multiaxis Hindfoot:- &#; A Multiaxis Hindfoot as an articulating component with urethane rubber bumpers, bushings, spherical snubbers, or large rings to dampen motion. &#; Separate modular ankle unit that can be used with a variety of prosthetic feet, or it may be integrated into the foot/ankle mechanism itself. &#; Multiaxis articulating designs often need regular maintenance and servicing. &#; Some variants extend the urethane sandwich from the forefoot to the hindfoot,
64. &#; 7. Integrated Shock Absorbers:- &#; It incorporate shock absorbers in a parallel or series configuration. &#; A series configuration is usually found with a damper more proximal to the spring-like foot. &#; A parallel design has a damper and spring at the same level. &#; The telescoping nature of many shock absorbers onsidered Nonphysiologic. &#; Design will be able to provide more variable stiffness or flexibility characteristics. &#; Future components are sure to continue this blending of qualities to provide greater foot function and movement.
