Hip Internal Rotation 90

Setup

Frame Setup Diagram

1: Lie on non-testing side, with hips at 90° flexion and knees at 90° flexion. Flat pad 1cm above lateral malleolus of upper leg.

2: Start with neutral transverse plane hip rotation. Use wedges/pillows to maintain separation of knees and feet and hip neutral in frontal plane.

3: If the subject has < 15° of internal rotation range, separate knees with towel/block 5cm for each 5° of IR lacking to ensure testing is not too near end of available hip IR range

4: Adjust subject and housing position to place pad lightly over lateral malleolus of the upper leg with sensor arm at right angles to tibia

Cues

1: Test unilaterally

2: Describe femoral rotation axis through femur, describing the plane of rotation (not abduction)

3: Squeeze ankle bone up into the sensor pad as knees stay together

4: No lifting of upper thigh or change in trunk position

5: Build to maximum force over 5 seconds
