StandingPatient's posture will reveal protective manoeuvers to alleviate pressure on hip: slightly flexed hip and ipsilateral knee. Shoulder height and height of iliac crest for leg length issues.GaitAdam's forward bendingTrendelenburg TestClinical popping, snapping or clicking
SeatedPatient will slouch and lean in the direction of the unaffected hip to lessen the degree of flexion to the affected side.Straight leg testBabinski testInternal and external rotation measurementsLudloffDeep tendon reflexes of Achilles and patella
SupineAssess musculature of the lower extremity visually and by measured thigh circumference. Differences in circumference in the affected and non-affected side may reflect chronic conditions and muscle atrophy.Straight leg testFADDIR test and
Scour test
Thomas testPatrick or FABER testMcCarthy test
LateralPatient lies on unaffected hip in the lateral decubitus position. Muscle tone should be assessed; if a large gluteus medius tear is present, the leg cannot lift.Tinel signSnapping of the iliotibial band: bicycle testOber testFADIR test
