Question 1

Which orthosis is the primary treatment for foot drop caused by peroneal nerve palsy?

Accepted Answer

Solid ankle AFO or articulated AFO with dorsiflexion assist

Answer

An AFO with a dorsiflexion assist or solid ankle prevents foot drop and provides foot clearance during the swing phase of gait.

Question 2

A child with spastic cerebral palsy and equinus deformity would benefit most from which AFO design?

Accepted Answer

Solid tone-inhibiting AFO (TIAFO) set at neutral dorsiflexion

Answer

A solid tone-inhibiting AFO holds the ankle at neutral dorsiflexion to inhibit spasticity and prevent progressive equinus deformity in children with cerebral palsy.

Question 3

In patients with multiple sclerosis, an orthosis is most likely prescribed for:

Accepted Answer

Foot drop and lower extremity weakness during gait

Answer

MS commonly affects the corticospinal tracts, leading to foot drop and lower extremity weakness managed effectively with an AFO.

Question 4

What is the primary orthotic goal for a patient with post-polio syndrome?

Accepted Answer

Substitute for weakened muscles and reduce energy expenditure during gait

Answer

Post-polio syndrome causes progressive weakness; orthoses substitute for lost muscle function to maintain mobility and reduce the metabolic cost of ambulation.

Question 5

A Charcot-Marie-Tooth patient presents with bilateral cavovarus deformity and foot drop. The most appropriate orthosis is:

Accepted Answer

Custom-molded solid ankle AFO

Answer

A custom-molded solid ankle AFO accommodates the rigid cavovarus deformity while simultaneously controlling foot drop in CMT disease.
