Question 25: Circumduction gait deviation most commonly results from:

Weakness of the hip abductors
Excessive ankle plantar flexor strength
An inability to adequately shorten the swing limb through flexion (Correct answer)
Excessive dorsiflexion range of motion

Correct answer: An inability to adequately shorten the swing limb through flexion

Circumduction occurs when the swing limb cannot shorten sufficiently (due to stiffness, brace length, or muscle weakness), so the patient swings the leg in a lateral arc to achieve ground clearance.

Question 26: Which part of the musculoskeletal system is affected by scoliosis?

Femur
Spine (Correct answer)
Pelvis
Skull

Correct answer: Spine

Scoliosis is a medical condition characterized by an abnormal, sideways curvature of the spine. It can affect any part of the spine, leading to a C- or S-shaped curve, and is a primary concern for orthotics specialists who often manage it with bracing.

Question 27: Which billing error involves submitting claims for services or devices that were not provided as documented?

Duplicate billing
Unbundling
Upcoding
Fraud (Correct answer)
