1: Attach the mid thigh pull bar to sensor 4 with the housing rotated 180 degrees.
2: Stand far side of the housing, adopt a staggered stance, on testing limb flex knee to 110 degrees and hip flexed to 120 degrees. Position testing foot slightly off center so knee does not come into contact with attachment cord. Maintain a positive shin angle with ankle Dorsi Flexed to 70 degrees. Rear foot used to provide additional stability for the athlete by maintaining ground contact with the great toe.
