What range of motion is most limited in the lumbar spine?

Question

Quizplus · Accepted Answer

The lumbar spine is designed to primarily support weight-bearing and provide stability, which limits motion. Rotation is the most restricted motion in the lumbar spine, as the orientation of the facet joints limits twisting movements that can potentially cause injury or instability. Lateral flexion and extension are also restricted to some extent, but flexion can occur more easily due to the shape of the intervertebral discs and the forward bend of the lumbar spine.
