Hip Adduction
Definition
The movement of the leg toward and across the midline in the frontal plane. Normal hip adduction range is approximately 20-30 degrees. The adductor group (adductor longus, brevis, magnus, gracilis, pectineus) produces this movement. Adductor length and strength are commonly asymmetric in the Left AIC pattern.
Clinical Significance
Adductor tightness and asymmetry are key findings in structural pattern assessment. In the Left AIC pattern, the left adductors are typically short and overactive while the right adductors are relatively lengthened. This creates asymmetric pelvic positioning and contributes to groin pain, hip impingement, and asymmetric squatting patterns. Adductor length comparison between sides is one of the confirming tests for structural pattern classification.
How AKMI Assesses This
AKMI measures adductor length bilaterally through passive abduction range in supine position. Left vs. right comparison is a key data point for Left AIC pattern identification. Cross-referenced with hip rotation data and pelvic obliquity findings.
