ORTHOTIC WRITTEN SIMULATION EXAM
SCRIPT 2026 FULL SOLUTIONS AND
CORRECT ANSWERS GRADED A+
⩥ Cerebral palsy: kafo. Answer: used at rest to maintain
musculotendinous length or prevent contracture
⩥ Cerebral palsy: foot deformity. Answer: external tibial torsion (mc);
distal Tibial valgus; forefoot valgus/varus
⩥ Cerebral palsy: internal foot posting. Answer: the floor is brought up
to the foot
⩥ Cerebral palsy: gait pathology and treatment. Answer: 1. reduce
spasticity
2. correct contractures
3. simplify the control system
4. preserve power generators
5. correct level arm dysfunction
⩥ Cerebral palsy: common cause for orthotic intolerance. Answer:
unrecognized coronal plane forefoot deformity (varus valgus)
,⩥ Cerebral palsy: ucbl or smo. Answer: commonly used for treatment of
CP
can control varus valgus hindfoot deformities
can compensate for forefoot deformities
arch support
⩥ Cerebral palsy: smo > ucbl. Answer: longer lever arm to control more
significant hindfoot deformities
⩥ Cerebral palsy: hinged afos. Answer: !younger children!
pf stop prevents footdrop in swing
flexible ankle joint allows mobility required for functional activities -
rising to standing, stair climbing, transitioning from on position to the
other.
⩥ Cerebral palsy: AfO safer for hemiplegia. Answer: hinged - less likely
to go into crouch
⩥ Proximal AFO trimline fib head clearance. Answer: 20mm
⩥ Change standard trimlines for flexible HF varus, SA AFO. Answer:
Sabolich tab, Lateral (Medial makes it worse)
⩥ 3 pt pressure system -
, Change standard trimlines for flexible HF varus, SA AFO. Answer:
Medial MTP, Lateral sabolich tab, proximal medial calf
⩥ Why would you extend SA SAFO posterior TL more proximal?.
Answer: Control/ decrease knee hyperextension (Inhibits knee flexion
while seated)
⩥ GRAFO - purposes etc. Answer: Crouch gait, contraindicated for knee
hyper extension and hip/knee contractures. Controls knee without
crossing.
Rigid footplate
⩥ Affected Muscle group shortened step on the sound side. Answer:
Plantarflexors
⩥ Type of AFO for tibial nerve lesion. Answer: Posterior lower leg
impacted - Hinged PF free DF stop
⩥ Hip flexor peripheral nerve. Answer: femoral Nerve
⩥ Patient exhibits Hallux rigidus - px in which part of gait. Answer: Late
Stance (?Pre swing?)
