Lumbar Spine Controlled Articular Rotation (CAR)

Methodical, breath-synchronized rotation of the lumbar spine to enhance articulator health and controlled range of motion.

Functional Range Conditioning (FRC) · Established by Dr. Andreo Spina within the Functional Range Conditioning (FRC) system. · Perceived lumbar stiffness, reduced spinal mobility, or a need to actively control end-range spinal movement without soft tissue mobilization. · Perform 3-5 repetitions in each direction, 1-2 times daily. Focus on controlled, deliberate movement rather than speed or maximal range, especially initially. As control improves, gradually expand the active range.

Why it works

Lumbar CARs involve activating the muscles surrounding the lumbar spine across its full, active range of motion. This systematic engagement signals to the nervous system that the available range is safe and controllable. The slow, controlled movement at the end range, coupled with isometric contractions (irradiation), progressively expands neurological control over the joint capsule and surrounding connective tissues, improving intervertebral health and proprioception. This can reduce tissue threat perception and improve global spinal mechanics.

How to practice

Starting Position: Lie supine (on your back) with knees bent and feet flat on the floor, about hip-width apart. Ensure your lower back is in a neutral position, not pressed flat or excessively arched. Place your hands lightly on your abdomen or by your sides.
Initiate Pelvic Tilt (Anterior): Gently arch your lower back by tilting your pelvis forward, bringing your pubic bone closer to your feet. Imagine "spilling water" out of the front of your pelvis. This is a subtle movement. Maintain a controlled breath.
Initiate Pelvic Tilt (Posterior): Next, gently flatten your lower back towards the floor by tilting your pelvis backward, bringing your pubic bone towards your face. Imagine "spilling water" out of the back of your pelvis. Continue with controlled, diaphragmatic breathing.
Combine and Circle: Begin to combine these tilts into a smooth, controlled circular motion. The goal is to articulate each segment of the lumbar spine, moving through anterior tilt, then to one side (lateral flexion), then posterior tilt, then to the other side (lateral flexion), completing the circle. The movement should be small and originate purely from the lumbar spine and pelvis, avoiding rocking the upper body or using momentum.
Maintain Tension: Throughout the movement, maintain a gentle, active tension in your core musculature (approximately 20% effort). This creates "irradiation," or tension, in the surrounding tissues, enhancing the neuromuscular signal to the joint.
Reverse Direction: After completing your prescribed repetitions in one direction, smoothly reverse the circular motion, moving with the same control and spinal articulation.
