Patella reflex

The patellar reflex ranks among the proprioceptive reflexes on the lower limb with L2–L4 root innervation. The examination of the patellar reflex is performed at 90° flexion of the lower limb in the hip and knee, by striking the patellar ligament with a hammer, i.e. striking between the  patella and the attachment of the quadriceps femoris muscle to the tibia. The physiological response is the adequate extension of the lower leg.
