Lower Extremity Biomechanics Quiz

Ankle joint is pivotal for both dorsiflexion and plantarflexion movements of the foot.

Quadriceps are the primary muscles responsible for knee extension.

The swing phase follows the stance phase during the walking cycle.

Biceps femoris is a hamstring muscle, not part of the quadriceps group.

Pronation refers to the inward rotation of the foot and ankle.

The tibialis anterior muscle group is chiefly responsible for dorsiflexion of the foot.

The arches of the foot primarily provide structural support, shock absorption, and weight distribution, not propulsion.

The primary function of the iliotibial band is to stabilize the knee during abduction movements of the hip.

The primary function of the patella is to increase the leverage of the quadriceps muscles during knee extension.

The ATFL is frequently injured in lateral ankle sprains due to its location and role in ankle stability.

The Achilles tendon is crucial for plantarflexion of the foot.

The plantar fascia plays a significant role in stabilizing the medial longitudinal arch of the foot.

Inversion and eversion movements predominantly occur at the subtalar joint.
