Question 1

The sartorius muscle is unique because it crosses which two joints?

Accepted Answer

Hip and knee

Answer

The sartorius is a biarticular muscle crossing both the hip and knee, functioning as a hip flexor/abductor and knee flexor.

Question 2

In gait analysis, 'cadence' is defined as:

Accepted Answer

The number of steps taken per unit of time

Answer

Cadence is the number of steps (or strides) per minute and is a key temporal parameter of gait.

Question 3

Which prosthetic foot feature is most beneficial for a transtibial amputee with a K3 activity level who frequently walks on uneven terrain?

Accepted Answer

Multiaxial dynamic response foot

Answer

A multiaxial dynamic response foot allows motion in multiple planes, improving stability and adaptability on uneven surfaces for active users.

Question 4

The 'double support' phase of gait refers to the period when:

Accepted Answer

Both feet are simultaneously in contact with the ground

Answer

Double support occurs twice per gait cycle (at initial contact and pre-swing) when both feet are simultaneously on the ground.

Question 5

Which bony landmark is most commonly used as the distal reference for measuring residual limb length in a transfemoral amputee?

Accepted Answer

Medial femoral condyle

Answer

The medial femoral condyle (or its equivalent in shorter residual limbs) serves as the standard distal reference point for transfemoral limb length measurement.
