Orthotic Written Simulation Exam 2026 | Actual Questions & Verified Answers
• This study guide contains 200 exam-style multiple choice questions with
verified answers, clear EXPERT RATIONALE, and full coverage of all orthotic
board exam domains — designed to simulate the real exam experience and
reinforce clinical reasoning.
• Each question follows a structured format: bolded stem, five labeled options
(A–E), a highlighted correct answer with EXPERT RATIONALE below — use it for
timed practice, topic review, or final exam preparation.
1. Which nerve is most commonly injured in lateral ankle sprains, leading to
sensory deficits on the dorsum of the foot?
A. Tibial nerve
B. Sural nerve
C. Deep peroneal nerve
D. Superficial peroneal nerve
E. Saphenous nerve
CORRECT ANSWER: D. Superficial peroneal nerve
EXPERT RATIONALE: The superficial peroneal nerve runs along the lateral
aspect of the lower leg and is vulnerable during lateral ankle sprains. It provides
sensory innervation to the dorsum of the foot and is the most commonly injured
nerve in such injuries.
2. A patient presents with foot drop. Which orthosis is most appropriate?
,A. Patellar tendon-bearing orthosis
B. Arizona AFO
C. Solid ankle-foot orthosis
D. Posterior leaf spring AFO
E. KAFO with drop lock knee joint
CORRECT ANSWER: D. Posterior leaf spring AFO
EXPERT RATIONALE: A posterior leaf spring (PLS) AFO is designed to assist
dorsiflexion during swing phase and control foot drop. It is lightweight, flexible at
the ankle, and ideal for patients with isolated dorsiflexion weakness without
significant spasticity.
3. The primary goal of a TLSO in the management of adolescent idiopathic
scoliosis is to:
A. Correct the curve surgically
B. Improve respiratory function
C. Prevent curve progression
D. Eliminate the curvature completely
E. Strengthen the paraspinal muscles
CORRECT ANSWER: C. Prevent curve progression
EXPERT RATIONALE: The TLSO (Thoracolumbar Sacral Orthosis), such as the
Boston brace, is prescribed for adolescent idiopathic scoliosis to halt or slow curve
progression during skeletal growth. It does not correct the curve but aims to
maintain it within acceptable limits.
4. Which of the following describes the Milwaukee brace?
A. A cervical orthosis used for torticollis
,B. A lumbosacral corset used for low back pain
C. A CTLSO used for high thoracic scoliosis
D. A KAFO used for polio patients
E. A spinal orthosis for lumbar stenosis
CORRECT ANSWER: C. A CTLSO used for high thoracic scoliosis
EXPERT RATIONALE: The Milwaukee brace is a Cervico-Thoraco-Lumbo-Sacral
Orthosis (CTLSO) indicated for scoliosis curves with an apex above T8. It includes a
pelvic girdle, uprights, and a neck ring with occipital and throat pads.
5. A patient with a transtibial amputation complains of pistoning in the
prosthetic socket. What is the most likely cause?
A. Excessive socket volume
B. Insufficient socket volume
C. Poor pylon alignment
D. Excessive prosthetic foot stiffness
E. Inadequate suspension system
CORRECT ANSWER: A. Excessive socket volume
EXPERT RATIONALE: Pistoning occurs when the residual limb moves up and
down within the socket during gait, which is most often caused by an oversized
socket or an inadequate suspension mechanism that cannot hold the socket
securely to the limb.
6. Which joint motion is controlled by a solid ankle AFO?
A. Knee flexion and extension only
B. Subtalar inversion and eversion only
C. Plantarflexion and dorsiflexion
, D. Hip abduction and adduction
E. Toe extension only
CORRECT ANSWER: C. Plantarflexion and dorsiflexion
EXPERT RATIONALE: A solid ankle AFO immobilizes the ankle joint, preventing
both plantarflexion and dorsiflexion. This provides stability for patients with
combined weakness or spasticity at the ankle.
7. The term "valgus" refers to:
A. Medial angulation of a distal segment
B. Posterior angulation of a distal segment
C. Lateral angulation of a distal segment
D. Anterior angulation of a distal segment
E. Rotational deviation of a distal segment
CORRECT ANSWER: C. Lateral angulation of a distal segment
EXPERT RATIONALE: Valgus deformity refers to lateral deviation of the distal
segment of a limb away from the midline. Genu valgum (knock-knee) is a common
clinical example.
8. Which of the following orthoses is indicated for Charcot-Marie-Tooth
disease?
A. Supramalleolar orthosis
B. Knee immobilizer
C. Rigid KAFO
D. Posterior leaf spring AFO
E. Cervical collar
