What you’re seeing here is a perfect example of hypermobility in the hip joint, specifically in flexion and rotation.
The Test:
1. Passive ROM: Her hip flexion, external rotation (>55 degrees), and internal rotation (>45 degrees) all exceed the normal range. This is her potential (passive) mobility.
2. Active ROM: When she performs internal rotation on her own (sitting up), the range drops significantly. This shows ~25 degree gap between her passive range and her active, controlled range.
The Fix:
A big passive-to-active gap means the joint is lacking stability and control within that massive range of motion. The training focus should shift from stretching to isolated hip stability and control work:
• Clamshells & Reverse Clamshells
• Cable-resisted Abduction/Adduction
• Closed-chain Internal/External Rotation
• Single-leg dominant movements (RDLs, Split Squats, Single-leg Squats)
