Left AIC Pattern
Definition
A structural pattern where the left anterior interior chain (left diaphragm, left psoas, left iliacus) is in a position of relative overactivity, pulling the left pelvis into anterior tilt and internal rotation. This is the most common structural pattern observed in biomechanical assessment, driven by the inherent anatomical asymmetry of the human body (liver on the right, heart on the left).
Clinical Significance
The Left AIC pattern creates a predictable set of compensations: the left pelvis tilts forward, the right pelvis compensates with relative external rotation, the lumbar spine side-bends right, and the thorax counter-rotates left. It explains why many people have reproducible left-right asymmetries in hip ROM, shoulder position, and weight-bearing distribution. Recognizing this pattern changes the intervention from bilateral correction to pattern-specific repositioning.
How AKMI Assesses This
AKMI identifies the Left AIC pattern through bilateral hip ROM comparison (internal vs. external rotation asymmetry), pelvic position assessment, rib cage orientation testing, and adductor/hamstring length comparison. The pattern is confirmed when multiple tests converge on the same structural presentation.
