In what plane of motion does hip adduction occur?

Hip adduction occurs in the frontal plane of motion. This plane divides the body into anterior (front) and posterior (back) sections. Movements in the frontal plane include actions that bring limbs toward or away from the midline of the body.

During hip adduction, the leg moves toward the body's midline, reducing the angle between the leg and the torso. This action is different from movements in the sagittal plane, which involve flexion and extension (like moving the leg forward or backward), or in the transverse plane, where rotational movements occur (like twisting the torso). The oblique plane involves combinations of movements from multiple planes but does not specifically apply to hip adduction, which is distinctly categorized within the frontal plane. Thus, understanding the correct classification of hip adduction is important for analyzing human movement and designing effective training or rehabilitation programs.
