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

    Answer: Ground reaction AFO (GRAFO)

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

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

    Answer: 90° flexion and 45–60° abduction

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

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

    Answer: Scottish Rite orthosis

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

  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?

    Answer: AFO with free ankle

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

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

    Answer: 25–40°

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

  6. Which brace design for adolescent idiopathic scoliosis (AIS) is designed to be worn only at night?

    Answer: Charleston bending brace

    The Charleston bending brace is a nighttime brace that overcorrects the curve while the patient sleeps, requiring only 8–10 hours of wear.

  7. In pediatric orthotics, 'Risser sign' is used primarily to assess what?

    Answer: Skeletal maturity of the iliac crest apophysis

    The Risser sign grades iliac crest apophysis ossification (0–5) to estimate remaining skeletal growth potential, which guides bracing decisions.
