Sample SCFHS Prosthetics and Orthotics Technician Practice Questions

Try these sample questions to review concepts for the SCFHS Prosthetics and Orthotics Technician exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1During the pre-prosthetic clinical evaluation of a patient with a transfemoral amputation, the practitioner conducts a Thomas test. Which physical finding specifically indicates a positive test for hip flexion contracture?
A.The tested thigh stays off the table while the other hip is flexed
B.The pelvis rotates laterally toward the tested side when the knee is passively extended
C.The lumbar spine flattens completely against the examination table without thigh elevation
D.The ipsilateral foot exhibits involuntary clonus during rapid passive hip flexion
Explanation: The Thomas test assesses hip flexion contracture (primarily tightness of the iliopsoas). With the patient supine, the contralateral hip is flexed toward the chest to eliminate compensatory lumbar lordosis. If a contracture is present on the tested limb, the hip cannot achieve neutral extension and the posterior thigh remains elevated off the examination surface.
2When obtaining anthropometric circumferential measurements of a mature transtibial residual limb for diagnostic socket fabrication, which anatomical reference landmark serves as the standard baseline level?
A.The superior border of the patella
B.The medial tibial plateau joint line
C.The apex of the head of the fibula
D.The distal end of the cut tibia
Explanation: The medial tibial plateau (MTP) joint line serves as the universal baseline landmark for transtibial residual limb measurement. Serial circumferences are measured at uniform intervals (commonly every 2 inches or 5 cm) distal from the MTP down to the distal end to accurately capture limb volume and taper.
3A patient with a transtibial prosthesis removes the socket after a 20-minute static weight-bearing trial. The prosthetist observes erythema over the patellar tendon and the shaft of the fibula that blanches on light digital pressure and completely resolves within 10 minutes. How should this finding be clinically interpreted?
A.Severe mechanical shear requiring immediate aggressive relief of the socket wall
B.Stage 1 pressure injury necessitating immediate suspension of prosthetic wear
C.Normal reactive hyperemia over designated pressure-tolerant regions
D.Allergic contact dermatitis secondary to the elastomeric liner material
Explanation: Transient blanchable erythema that fades within 10 to 15 minutes after load removal represents normal reactive hyperemia in response to physiological weight-bearing over pressure-tolerant anatomical regions such as the patellar tendon and fibular shaft. Non-blanchable erythema persisting beyond 20 to 30 minutes indicates excessive focal pressure requiring socket modification.
4During lower extremity orthotic assessment, the orthotist evaluates the dorsiflexor muscle group using the Medical Research Council (MRC) manual muscle testing scale. The patient actively achieves full range of ankle dorsiflexion against gravity and withstands moderate manual resistance before yielding. What grade should be assigned?
A.Grade 2 (Poor)
B.Grade 3 (Fair)
C.Grade 5 (Normal)
D.Grade 4 (Good)
Explanation: According to the MRC scale, Grade 4 (Good) denotes complete active range of motion against gravity combined with moderate manual resistance. Grade 3 achieves full range against gravity only (yielding to any resistance), Grade 5 resists maximal force, and Grade 2 requires gravity-eliminated positioning.
5An orthotist performs the Silfverskiold test to determine the cause of limited ankle dorsiflexion. The test reveals 0 degrees of ankle dorsiflexion when the knee is fully extended, which increases to 15 degrees of dorsiflexion when the knee is flexed to 90 degrees. What underlying condition does this finding demonstrate?
A.Isolated gastrocnemius contracture
B.Isolated soleus muscle contracture
C.Fixed posterior ankle capsular tightness
D.Bony anterior tibiotalar impingement
Explanation: The gastrocnemius is a biarticular muscle originating from the femoral condyles and inserting onto the calcaneus, whereas the soleus is monoarticular originating below the knee. Flexing the knee relaxes the gastrocnemius. Significant gain in dorsiflexion upon knee flexion proves the restriction is caused by isolated gastrocnemius contracture.
6Which peripheral nerve curves superficial to the bone directly around the neck of the fibula, making it exceptionally susceptible to compression injury from improper AFO proximal trimlines or unpadded prosthetic socket brims?
A.Tibial nerve
B.Common peroneal (fibular) nerve
C.Saphenous nerve
D.Obturator nerve
Explanation: The common peroneal (fibular) nerve bifurcates from the sciatic nerve and wraps intimately around the lateral aspect of the fibular neck before dividing into deep and superficial branches. Because of its subcutaneous location against bone, pressure from an AFO calf band or transtibial socket brim can cause neuropathy leading to foot drop and lateral sensory loss.
7In transfemoral socket design, the anterior brim geometry frequently incorporates Scarpa's bulge to stabilize the residual limb. What anatomical structure forms the superior anatomical border of Scarpa's (femoral) triangle?
A.Sartorius muscle
B.Adductor longus muscle
C.Inguinal ligament
D.Gracilis tendon
Explanation: Scarpa's (femoral) triangle is bounded superiorly by the inguinal ligament, laterally by the medial border of the sartorius muscle, and medially by the medial border of the adductor longus muscle. In quadrilateral and ischial containment sockets, the anterior wall contour maintains the limb posteriorly against the ischial seat.
8Loss of coronal plane hip stabilization during single-limb prosthetic stance most commonly results from denervation or mechanical deficiency of which primary hip abductor muscle?
A.Gluteus maximus
B.Pectineus
C.Tensor fasciae latae
D.Gluteus medius
Explanation: The gluteus medius is the primary hip abductor muscle, originating from the ilium and inserting onto the greater trochanter of the femur. During single-limb stance, it contracts to prevent the contralateral pelvis from dropping. In transfemoral amputations, preserving its mechanical lever arm through socket adduction is essential for coronal stability.
9Which primary ligamentous stabilizer of the knee joint prevents excessive anterior translation of the tibia relative to the femur and resists hyperextension, informing the anterior-posterior stop mechanics of functional knee braces?
A.Anterior cruciate ligament (ACL)
B.Posterior cruciate ligament (PCL)
C.Medial collateral ligament (MCL)
D.Arcuate popliteal ligament
Explanation: The anterior cruciate ligament (ACL) originates from the medial surface of the lateral femoral condyle and inserts into the anterior intercondylar area of the tibia. Its primary biomechanical function is resisting anterior tibial translation and secondary resistance to internal rotation and hyperextension.
10The subtalar (talocalcaneal) joint is critical in lower limb orthotics because its oblique triplanar axis couples ankle motion with which primary triplanar movements of the hindfoot during the gait cycle?
A.Isolated sagittal flexion and extension
B.Pronation and supination as coupled triplanar motions
C.Axial distraction and compression along the vertical tibial axis
D.Pure frontal plane translation without rotation
Explanation: The subtalar joint axis is inclined approximately 42 degrees superiorly from the horizontal plane and angled 16 to 23 degrees medially from the sagittal plane. This oblique orientation ensures that triplanar pronation (eversion, abduction, dorsiflexion) and supination (inversion, adduction, plantarflexion) occur as unified coupled motions.
