CO Gait Analysis & Lower Extremity Biomechanics 2

Question 1

Trendelenburg gait is characterized by which of the following findings during single limb stance?

Accepted Answer

Contralateral pelvic drop on the swing limb side

Answer

Ipsilateral trunk lean toward the stance limb

Answer

Excessive knee flexion on the stance side

Answer

Circumduction of the stance limb

Question 2

A patient with foot drop (weak or absent dorsiflexors) most commonly exhibits which compensatory gait pattern?

Accepted Answer

Steppage gait

Answer

Antalgic gait

Answer

Trendelenburg gait

Answer

Scissor gait

Question 3

Scissor gait, characterized by hip adduction and internal rotation crossing the midline during swing, is most commonly associated with which condition?

Accepted Answer

Spastic diplegic cerebral palsy

Answer

Peripheral neuropathy

Answer

Hip osteoarthritis

Answer

Lumbar disc herniation

Question 4

Antalgic gait is best described as a gait pattern in which:

Accepted Answer

The stance phase is shortened on the painful limb to minimize time bearing weight

Answer

The hip drops on the contralateral side during stance

Answer

The patient rises on the toes to assist limb clearance

Answer

The swing limb is circumducted to avoid knee flexion

Question 5

A 'vaulting' gait deviation occurs when the patient:

Accepted Answer

Rises onto the toes of the stance limb to provide clearance for the swing limb

Answer

Leans the trunk laterally toward the affected side

Answer

Swings the swing limb in a wide lateral arc

Answer

Hyperextends the knee during mid-stance

Question 6

When the quadriceps are severely weak during mid-stance, which gait deviation is most commonly observed?

Accepted Answer

Forward trunk flexion or knee recurvatum (hyperextension)

Answer

Crouch gait

Answer

Steppage gait

Answer

Trendelenburg gait

Question 7

Circumduction gait deviation most commonly results from:

Accepted Answer

An inability to adequately shorten the swing limb through flexion

Answer

Weakness of the hip abductors

Answer

Excessive ankle plantar flexor strength

Answer

Excessive dorsiflexion range of motion
