The patellar reflex occurs when there is a sudden change in muscle length. In this situation, apply a hammer blow to stretch the tendon [3, 4].
A quick leg extension should be the expected response. A decrease or increase in response is a sign of damage or disruption in the quadriceps innervation. Her L2, L3, and L4 levels of the spinal cord, spinal neurons located primarily in the L4 root, mediate the patellar reflex, a deep tendon reflex.
A patellar reflex test is performed by striking the patellar tendon under the patella with a test hammer to determine the neurological functional integrity of the peripheral nervous system and may alter the patellar reflex response.
Other variables, such as stroke severity, the patient's level of anxiety during the test, and the patient's age, can also affect the outcome of the test.
Right knee +2; left knee +1 is the right way to document.
