Question 1

A child with cerebral palsy demonstrates excessive knee flexion during stance phase. Which orthotic intervention is most appropriate?

Accepted Answer

Ground reaction AFO (GRAFO)

Answer

A ground reaction AFO creates an extension moment at the knee during stance, directly addressing crouch gait caused by excessive knee flexion.

Question 2

When fitting a Pavlik harness for developmental dysplasia of the hip (DDH), what hip position should be maintained?

Accepted Answer

90° flexion and 45–60° abduction

Answer

The Pavlik harness positions the hip in approximately 90° of flexion and 45–60° of abduction to seat the femoral head in the acetabulum.

Question 3

Which orthosis is most commonly used for Legg-Calvé-Perthes disease to maintain femoral head containment?

Accepted Answer

Scottish Rite orthosis

Answer

The Scottish Rite (Atlanta) orthosis holds the hips in abduction to contain the femoral head within the acetabulum while allowing ambulation.

Question 4

A 4-year-old with myelomeningocele at L3–L4 has active hip flexors and quadriceps but no ankle control. What is the most likely appropriate orthosis?

Accepted Answer

AFO with free ankle

Answer

With preserved quadriceps and hip flexors but absent ankle musculature, an AFO providing ankle-foot control while allowing knee function is most appropriate.

Question 5

Scoliosis bracing with a TLSO is generally indicated when the Cobb angle falls within which range in a skeletally immature patient?

Accepted Answer

25–40°

Answer

Bracing is indicated for curves between 25–40° Cobb angle in skeletally immature patients to halt progression without surgery.
