3
Q
- Which statements are true?
a. over-supination promotes knee varus, hip external rotation, and a PPT
b. over-pronation promotes knee valgus, hip internal rotation, and an APT
A
both are true
4
Q
- Which statements are true?
a. supination involves shock-absorption
b. pronation involves propulsion
A
neither are true
5
Q
- Which statements are true?
a. pronation involves the reactive, stretch phase
b. supination involves the active, shortening phase
A
both are true
6
Q
- Which statements are true?
a. supination involves the eccentric phase in which key muscles elongate
b. pronation involves the concentric phase in which key muscles shorten
A
neither are true
7
Q
- Which statements are true?
a. during pronation, the gastrocnemius stretches; during supination, the gastrocnemius shortens
b. during pronation, the gastrocnemius shortens; during supination, the gastrocnemius stretches
A
a
8
Q

- talocrural joint
- subtalar joint
- transverse tarsal joint
A
b
9
Q
- If the talus bone points inward (medially), the foot is _____; if the talus bone points outward (laterally), the foot is _____.
- supinated; pronated
- pronated; supinated
A
b
10
Q
- Which statements are true?
a. the subtalar joint and ankle can’t function optimally when the feet are turned outward (duck) or inward (pigeon) excessively during gait
b. when walking or running, most arm motion should occur at the elbow joint versus the shoulder joint
A
a
11
Q
- Which statements are true?
a. when walking or running, as your navel rotates one way, your pelvis should rotate the opposite way
b. when walking or running, your navel should rotate about two-inches toward the lead leg during each step
A
a
12
Q
- Which statements are true?
a. the spinal engine generates and releases elastic energy to improve exercise economy
b. when walking, foot/heel contact should normally not be in front or behind the gravity line reference point
A
both are true
13
Q
- Which statements are true?
a. at midstance your weight pressure should shift along the subtalar axis to promote foot eversion and abduction; as this occurs, it promotes slight dorsiflexion along the ankle axis
b. at push-off, your weight pressure should shift along the subtalar axis to promote foot inversion and adduction; as this occurs, it promotes plantar flexion along the ankle axis
A
both are true
14
Q
- This participant could improve the _____ phase of her gait pattern.
- pronation
- supination
A
a
15
Q
- Which statements are true?
a. a noisy gait means too much force is being delivered to the feet, ankles, knees, hips, and spine
b. a proper toe push-off is crucial in maintaining normal fore-foot and toe ROM, along with proper activation of the gastrocnemius and soleus
A
both are true
