Explore the lumbar spine’s anatomy and arthrokinematics

Welcome to The Movement PhD!This is Season 1, Episode 7.

In this episode, Dr. Dustin Hardwick (PhD in Movement Science, Physical Therapist) explains the structure and movement mechanics of the lumbar spine. You’ll learn how spinal curves distribute load, how vertebrae and discs handle compression and shear, and how the facet orientation guides motion. We also review key ligaments, the arthrokinematics of flexion, extension, rotation, and lateral flexion, and how posture affects spinal forces.

Whether you’re a student, clinician, or movement professional, this episode gives you a clear anatomical and mechanical foundation for understanding lumbar spine function.
