Vertical Suspension Positioning

How to perform the "Vertical Suspension Positioning"?

• The infant is held upright and facing away from the examiner, with the examiner’s hands under the axillae for support. 
• Normally, the infant will maintain the head in the midline and flex the legs at the hips and knees. 

What is the positive result?

• Fixed extension and crossed adduction of the legs (scissoring) indicate spastic paraplegia or diplegia.
• This reflex normally disappears after 4 months of age.
