Final answer:
At initial contact, the hip is in medial (internal) rotation, which allows for proper alignment during gait as the foot meets the ground.
Step-by-step explanation:
During initial contact in gait, the hip is generally in a position of medial (internal) rotation. This position allows for the alignment of the lower extremity as the foot makes contact with the ground, facilitating a smooth transfer of weight and momentum. Medial rotation refers to the movement that brings the anterior surface of the limb toward the midline of the body. In contrast, lateral (external) rotation moves the anterior surface away from the midline. Both of these movements can only occur at the multiaxial shoulder and hip joints, such as the ball-and-socket joint of the hip, which is instrumental for both stability and a wide range of motion.
