Iliopsoas stretching
hyperextension
Stretching was executed in crook lying, with both lower limbs hanging at the end of the table, so that the stretched hip could be reached beyond neutral. The opposite hip and knee were bent toward the patient's chest while stretching to support the pelvis and spine. The hip to be stretched, moved into extension or hyperextension while stabilizing the opposite leg by applying downward pressure to the anterior aspect of the distal thigh. The knee could be extended so that the two-joint rectus femoris would not limit the range. Stretching was kept for 30 seconds. The same procedures were applied on the other side
