Hip 90-90 Rotation Injury Screen
Hip 90-90 rotation injury screen compares internal and external hip rotation side by side—asymmetry before lunges and splits predicts compensation under load better than a quick toe-touch.
Hip 90-90 rotation injury screen sits both legs bent at ninety degrees—front leg externally rotated, back leg internally rotated—to compare left-right hip rotation comfort before lunges, splits, and rotational sports. Asymmetry or pinching flags need targeted CARs and 90-90 switches, not forcing depth into pain.
Note which side blocks internal versus external rotation. Brief daily switches often beat weekly long holds alone.
Screen monthly, not obsessively daily. Hip rotation limits drive knee valgus and low-back twist under load.
Common questions
-
What if only one side pinches in 90-90?
Work the limited side with smaller ranges, CARs, and switches—avoid forcing the painful arc. Persistent pinching with loading warrants a clinician movement assessment.
