Welcome to The Movement PhD!
This is Season 1, Episode 10: The Knee: Bony Anatomy, Alignment, and Arthrokinematics.

In this first part of the knee unit, Dr. Dustin Hardwick (PhD in Movement Science, Physical Therapist) reviews the anatomy and mechanics of the knee joint. You’ll learn about the tibiofemoral, patellofemoral, and proximal tibiofibular joints, normal alignment angles, and how forces act through the knee during standing and movement.

We’ll review anatomy, alignment, the screw-home mechanism, how the patella enhances quadriceps function, and the arthrokinematics.. This episode provides the mechanical foundation for understanding knee movement and injury mechanics in both clinical and functional settings.

In the next episode we will continue our discussion of the knee with a discussion of the muscles, ligaments, and how they contribute to movement.

Explore how the sacroiliac joint and posture contribute to lumbar movement and pain syndromes.

Welcome to The Movement PhD!
This is Season 1, Episode 9: The Sacroiliac Joint and Lumbar Movement Syndromes.

In this episode, Dr. Dustin Hardwick (PhD in Movement Science, Physical Therapist) explains the role of the sacroiliac joint as the bridge between the spine and lower limbs and explores how posture and movement patterns affect lumbar function. You’ll learn about nutation and counternutation, SI joint stability, and common lumbar movement syndromes, from hyperlordosis and facet loading to flexion-based disc pathology and instability.

Whether you’re a student, clinician, or movement professional, this episode brings together the anatomy, mechanics, and common pathologies of the lower back to complete the lumbar spine unit.

Welcome to The Movement PhD!
This is Season 1, Episode 8: The Lumbar Spine Part 2: Lower Back and Abdominal Muscles

In this episode, Dr. Dustin Hardwick (PhD in Movement Science, Physical Therapist) reviews the muscles that move and stabilize the lumbar spine and abdomen. You’ll learn how the abdominals, deep back muscles, diaphragm, and pelvic floor work together to create stability, manage load, and coordinate movement.

We’ll discuss the function of each muscle group, how they interact to produce flexion, extension, lateral flexion, and rotation, and how core timing—especially activation of the transversus abdominis and multifidus—affects spinal control. Whether you’re a student, clinician, or trainer, this episode helps you connect structure to movement and movement to performance.

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.

This is Season 1, Episode 6: Hip Function in Normal and Pathological Gait

In this final part of the hip series, Dr. Dustin Hardwick (PhD in Movement Science, Physical Therapist) connects anatomy and muscle function to real-world movement. You’ll learn how the hip contributes to each phase of gait, from initial contact to terminal swing, and how internal and external moments shape stability and propulsion. We’ll also review common gait deviations—like Trendelenburg, dynamic valgus collapse, glute max lurch, and hip flexor contracture—and the underlying muscle mechanics behind them.

Whether you’re a student, clinician, or movement professional, this episode ties together the structure, function, and clinical implications of the hip in motion, setting the stage for our next unit on the lumbar spine.

A breakdown of hip muscle actions, force couples, and their role in posture and movement.In this episode, Dr. Dustin Hardwick (PhD in Movement Science, Physical Therapist) reviews the muscles that cross the hip joint and their role in movement across all planes. You’ll learn the primary hip flexors and extensors, how abdominals stabilize hip flexion, the role of adductors and abductors in pelvic control, and why the posterior fibers of the gluteus medius are key for anti-gravity stability. We’ll also explore internal and external rotators, force couples for pelvic tilts, and how torque capacity differs among hip muscle groups. This episode connects anatomy to function and lays the groundwork for our upcoming discussion on the hip in gait.
