Which phase of the gait cycle is characterized by the initial contact of the heel with the ground?
Initial Contact
Midstance
Terminal Stance
Pre-Swing
Initial Contact is the very first phase of the gait cycle when the heel strikes the ground. It sets the stage for loading response and proper weight transfer through the foot.
Pronation of the foot during stance phase primarily involves which movement?
Outward rolling of the foot
Forefoot inversion
Excessive toe dorsiflexion
Inward rolling of the foot
Pronation refers to the inward rolling motion of the subtalar joint, allowing shock absorption. It combines calcaneal eversion, forefoot abduction, and dorsiflexion.
Which orthotic material is known for the highest rigidity and stiffness?
EVA foam
Cork
Carbon fiber
Thermoplastic polyurethane
Carbon fiber has a very high stiffness-to-weight ratio, making it the most rigid common orthotic material. It provides excellent structural support and minimal deformation under load.
A longitudinal arch support orthotic is primarily used to address which condition?
Metatarsalgia
Pes cavus (high arch)
Pes planus (flatfoot)
Achilles tendonitis
A longitudinal arch support helps elevate and support the medial arch, reducing collapse in flatfoot. It limits excessive pronation and improves alignment.
Which assessment technique is traditionally used to capture the static foot shape for a custom orthotic?
Dynamic pressure mapping
Goniometer measurement
Visual gait observation
Plaster casting
Plaster casting provides an accurate negative mold of the static foot shape in subtalar neutral. This cast serves as the basis for creating a custom orthotic shell.
Excessive forefoot abduction observed during midstance most likely indicates which gait deviation?
Plantarflexion contracture
Dorsiflexion restriction
Supination
Overpronation
Excessive forefoot abduction (toeing-out) is commonly a sign of overpronation, where the foot rolls inward and the forefoot moves laterally. This alters weight distribution through midstance.
When designing an orthotic for plantar fasciitis, which feature is most essential?
High medial arch support
Extended metatarsal pad
Forefoot rocker
Lateral forefoot wedge
High medial arch support reduces tensile strain on the plantar fascia by maintaining the foot's arch. This decreases fascial stretching during stance.
Which material property is most important for energy return in a performance-oriented orthotic?
Hardness
Density
Resilience
Thickness
Resilience describes how well a material returns energy after deformation. High resilience in orthotic materials can improve push-off and reduce energy loss.
A patient has a rearfoot varus alignment in subtalar neutral. Which orthotic posting compensates for this?
Medial metatarsal pad
Lateral heel wedge
Forefoot valgus wedge
Medial heel wedge
Rearfoot varus (inverted calcaneus) is offset by a lateral heel wedge, which brings the calcaneus to a more neutral vertical position under the tibia.
According to clinical guidelines, which orthotic type is recommended first-line for mild pes cavus?
Rocker-bottom sole insert
Semirigid functional orthotic
Rigid custom orthotic
Soft prefabricated cushioned orthotic
Mild pes cavus patients often benefit from a soft, cushioned prefabricated orthotic that provides shock absorption without overcontrolling foot motion.
A pressure map shows a peak under the second metatarsal head. To reduce this peak pressure, you would add:
Metatarsal pad proximal to the heads
Rigid longitudinal arch support
Increased heel elevation
Forefoot lateral wedge
A metatarsal pad placed just proximal to the metatarsal heads redistributes load proximally along the metatarsal shaft, reducing pressure under the heads.
An increased external foot progression angle during gait often indicates:
Tibial external torsion
Achilles tendon tightness
Subtalar pronation
Femoral anteversion
An out-toeing gait (increased progression angle) is commonly due to external tibial torsion. It rotates the foot outward relative to the line of progression.
Which design feature on an orthotic shell best helps control overpronation?
Forefoot rocker
Metatarsal dome
Medial flange
Lateral flange
A medial flange acts as a barrier against excessive pronation by reinforcing the medial side of the rearfoot and arch, limiting inward collapse.
For a diabetic patient at high risk of ulceration, the primary orthotic goal is to:
Include a lateral forefoot wedge
Elevate the heel significantly
Increase medial arch rigidity
Distribute plantar pressures evenly
Even pressure distribution across the plantar surface minimizes focal high pressures that can lead to ulceration in diabetic neuropathy patients.
When casting for subtalar neutral, which landmark alignment is most critical?
Talar head prominence symmetrical
Navicular aligned with first metatarsal
Forefoot and rearfoot 0° to each other
Calcaneal bisection aligned with long axis of tibia
Aligning the calcaneal bisector with the tibial axis ensures the subtalar joint is in neutral, which is essential for a functional orthotic fit.
During midstance a patient shows premature rearfoot inversion causing lateral overload. Which orthotic strategy is most appropriate?
Increase medial arch height
Use a metatarsal dome
Add a lateral forefoot wedge
Add a medial forefoot wedge
A lateral forefoot wedge shifts load medially at push-off and delays excessive inversion, reducing lateral column overload during midstance.
A patient has tibial internal torsion resulting in in-toeing. Which orthotic modification may help?
Lateral metatarsal pad
External rotation heel wedge
Medial arch relief cut-out
Forefoot varus wedge
An external rotation heel wedge rotates the foot laterally during stance, partially compensating for tibial internal torsion and reducing in-toeing.
Why is carbon fiber often selected for high-performance athletic orthotics?
Superior cushioning properties
Maximum flexibility under load
Excellent moisture wicking
High stiffness-to-weight ratio and energy return
Carbon fiber offers exceptional stiffness while remaining lightweight, and its resilience returns stored energy to the foot, enhancing performance.
A patient with cavovarus deformity presents with a callus under the fifth metatarsal head. Which orthotic design is recommended?
Lateral heel wedge and reverse Morton's extension under first metatarsal
Rocker sole and heel lift
Medial heel wedge and full-length metatarsal pad
Forefoot valgus wedge and arch relief
A lateral heel wedge reduces cavus rearfoot varus, while a reverse Morton's extension offloads the lateral forefoot, relieving pressure under the fifth metatarsal.
Which clinical test best predicts the severity of pronation requiring orthotic support?
Center of pressure excursion index
Foot posture index
Rearfoot eversion angle measurement
Navicular drop test
The navicular drop test quantifies the change in arch height from sitting to standing, directly measuring pronation magnitude and guiding orthotic intervention.
