Goes from the calcaneus, under Met. Heads and inserts into base of proximal phalanges
What is Plantar Aponeurosis
100
Equally distributed between Calcaneus and metatarsal heads
What is Weight bearing of the foot?
100
By palpation can feel the area of tenderness
The area is approximately 1cm in diameter
Can develop to callus deformity and be a cronic condition.
What is Plantar fasciitis?
100
Elasticity, plasticity, Strength, Brittleness, Density
What is Material Properties?
100
Shock Absorber (heel strike)
Stabilizing the arch of the foot
Provide the base of support to maintain balance
Torque absorber for transverse limb rotation.
Weight distribute over plantar surface
What is goal of orthotic treatment?
200
Joint has an important role in gait, especially in final phase of gait and push-off
What is MTP Joint?
200
Plantar aponeurosis tightens Aponeurosis is shortened,
Raises the longitudinal arch causing a rigid and stabilized structure.
In Adults
Accommodate the deformity
relief pain & provide Shock absorption to the heel
What is Pes Cavus?
300
Synovial hinge Joint
Passive ROM
Dorsiflexion = 20°
Plantarflexion = 50°
What is Talucrural Joint
300
Calcaneus everts but head of the talus compensates for the distally fixed foot by adducting and plantarflexing.
What is Closed Chain Pronation?
300
Nerve damage, often causes weakness, numbness and (burning) pain. Caused by traumatic injuries, infections, metabolic problems and exposure to toxins
What is Peripheral neuropathy?
300
3 point pressures
Ground Reaction Forces
What is Correction?
300
Creating a new habit by plantar flexion resist/ stop. Shoe, cast or AFO. Neurogene TW: Stregthing or surgical lengthening of muscle. AFO follow-up
What is What is habitual/ Idiopathic Toe-Walking?
400
Place your thumb on the 4th and 5th metatarsals with your opposing fingers gripping the 4th and 5th metatarsals. Then with your opposite hand feel the anterior surface of the talus.
How do you achieve subtalar neutral?
400
Talus and leg do not move, while the calcaneus moves through all three body planes and carries the foot with it.
What is Open chain Motion?
400
Etiologic:
Lack of protective sensation.
Continues walking after injury
Inflammation and increased blood flow
Bone Weakness (reabsorption of minerals)
Fractures
What is Charcot foot?
400
Type of pathology and function lost
Availability of material
Cost
Appropriate tools and machinery
What is Factors that are affecting the choice of the material ?
400
X-ray for investigation of Talsal coalition
If pain => Supportive insoles
What is rigid pes plano valgus?
500
Origin:Upper half of posterior shaft of tibia, fibula and interosseous membrane.
Insertion:All tarsal bones (except talus).
What is Tibialis posterior?
500
During gait moves from the heel forward to the toes, according to initial contact to pre swing (Heel contact to toe off).
What is GRF?
500
Reduced or lack of protective sensation in the foot.
Caused by damages of small blood vessels which lead to nerve damage
What is Insensate Foot?
500
Consist of 90% PP 10% PE; Excellent self adhesion when hot. Between PP and PE in rigidity and brittleness
What is Copolymer?
500
Aim is to decrease local pressure & shear forces.
Accommodate and support the foot.
