In the posterior–anterior posture pattern described in the Saliba Postural Classification System from the Institute of Physical Art, the body develops an imbalance between the front and back that often leads to stiffness or restricted movement at the thoracolumbar (TL) junction — where the mid-back meets the lower back.
When this area loses mobility, the body begins to compensate.
🔹 The lower back muscles become overactive and tight, causing discomfort and fatigue.
🔹 The thoracic spine and rib cage grow less mobile, limiting the diaphragm and creating shallow, inefficient breathing.
🔹 The upper body may shift into rounded shoulders and forward head posture, increasing tension through the neck, shoulders, and upper back — sometimes contributing to neck pain and headaches.
This creates a chain reaction where restricted motion at the TL junction affects posture, breathing patterns, muscle balance, and overall movement efficiency.
Restoring mobility and control through postural retraining, breathing exercises, and core stabilization can help relieve strain, improve alignment, and reduce pain throughout the spine.
