Multiple Choice
Identify the choice that best completes the statement or answers the question.
____ 1. A therapist examines a knee–ankle–foot orthosis with an articulating ankle joint. Which of the following correctly describes the desired location of the orthotic ankle joint with respect to the patient’s ankle?
a. The medial joint is one-half inch posterior to the apex of the medial malleolus, and the lateral joint is one-half inch anterior to the apex of the lateral malleolus.
b. The medial joint is at the apex of the medial malleolus, and the lateral joint is at the apex of the lateral malleolus.
c. The mechanical (orthotic) ankle axis is parallel to the knee axis.
d. Only A and C are correct.
e. Only B and C are correct.

____ 2. A therapist examines a knee–ankle–foot orthosis with an articulating knee joint. Which of the following correctly describes the desired location of the orthotic knee joint with respect to the patient’s knee?
a. The medial knee joint is one-half inch anterior and superior to the medial epicondyle.
b. The lateral knee joint is midway between the anterior and posterior surfaces of the knee at the level of the knee joint line.
c. The orthotic knee axis is parallel to the ankle axis in the transverse plane.
d. None of the choices (A, B, C) are correct.

____ 3. A patient wearing a transfemoral prosthesis has developed a hip flexion contracture after the prosthesis was fit and received by the patient. In static standing, this will most likely cause the line of gravity to produce an undesirable ____ on the prosthetic side.
a. Hip flexion moment
b. Knee flexion moment
c. Knee extension moment
d. A and C
e. A and B
____ 4. A patient has a flexible varus deformity at the ankle due to a muscle imbalance. A therapist selects an ankle–foot orthosis to minimize the unwanted varus using three-point counterforces. To be effective, the orthosis must provide a middle force that is directed ____.
a. Lateral to medial
b. Medial to lateral
c. Anterior to posterior
d. Posterior to anterior
____ 5. A therapist examines an ankle–foot orthosis that has componentry that stops dorsiflexion at 0° (neutral) and plantarflexion at 40°. The problem that this orthosis was most likely prescribed to improve is ____.
a. Foot drop
b. Insufficient push-off
c. Insufficient knee flexion
d. Insufficient knee extension
