1.) Subgrouping All Feet into Functional Foot Types May Be Helpful Because It:(Required)

a. Allows all feet in each Foot Type to be treated and monitored more aggressively

b. Prevents harm and injury to feet in other Functional Foot Types

c. Points to areas of Root Cause Inherited, underpinning Biomechanical Pathology

d. All of the above

2.) Stability, Support, Strength, Symmetry and Balance of the Posture are Rooted Primarily in the:(Required)

a. Ankle

b. Rearfoot

c. Midfoot

d. Forefoot

3.) The Structure or BioMachine most involved in controlling the Flexible Adapter-Rigid Lever Shift in a Closed Chain Foot Is:(Required)

a. The Plantar fascia – Windlass

b. The BioKIckstand of the Foot

c. The Subtalar Joint

d. The Posterior Tibial Muscle Engine

4.) What are some of the goals of foot orthosis therapy?(Required)

A. To increase the loading forces on the structural components of the lower extremity to make them stronger.

B. To prevent new injuries from occurring.

C. To promote more efficient dynamics during weightbearing activities.

E. All of the above

D. B and C

5.) Regarding the spatial location of the subtalar joint axis, which of the following are true?(Required)

A. Feet with pronation-related gait and symptoms generally have medially deviated subtalar joint axes.

B. Medial deviation of the subtalar joint axis is associated with a more externally rotated talar head and neck relative to the plantar foot.

C. A foot with a medially deviated subtalar joint axis must be supported by a foot orthosis more laterally to increase the subtalar joint supination moment from the orthosis.

D. A foot with a laterally deviated subtalar joint axis must be supported by a foot orthosis more medially to increase the subtalar joint pronation moment from the orthosis.

E. A, C and D

6.) In regards to stress in the tissues of the foot and lower extremity, which of the following are true?(Required)

A. As strain increases, so does stress increase in ligament, tendon and bone.

B. Stiffness in ligament, tendon and bone is represented by the slope of their stress-strain curve.

C. When ligament, tendon and bone are placed under relatively low loads, they tend to undergo elastic deformation.

D. All of the above.

E. None of the above.

7.) Over pronation is caused by sedentary lifestyles, decreased muscle tone and high cholesterol.(Required)

A. True

B. False

8.) A forefoot diagnosis of plantar warts is caused by over-pronation.(Required)

A. True

B. False

9.) An equal and opposite range of forces to that which the human body applies to the orthotic follows Newton’s Law of Physics: For every action there is an equal and opposite reaction.(Required)

A. True

B. False

10.) According to most major studies, traditional custom foot orthotics are mechanically no better than prefabricated orthotics for plantar fasciitis.(Required)

A. True

B. False
