Hip ER 0

Setup

Frame Setup Diagram

1: Lie on testing side, with hips and trunk neutral and knee at 90° flexion. Flat pad 1cm above medial malleolus

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 player has < 15° of internal rotation range, raise the housing one position for every 5° of IR lacking. This allows MVIC to be measured closer to the subject's hip neutral position

4: Rotate housing to ensure flat pad is flush with apex of malleolus and the sensor arm is at right angles to tibia

Cues

1: Test unilaterally, with opposing leg supported by pillow or wedge

2: Describe femoral rotation axis

3: Squeeze ankle bone into pad as 'femur falls to floor'

4: Feel deep hip rotators (deep in low gluteals) working

5: Discourage activation of adductors

6: Bracing of the upper body using a kettle bell or similar is permitted

7: Build to maximum force over 5 seconds
