* Testing deep tendon reflexes is an important part of the newborn neurological exam. They can be technically difficult to do. The first thing is to use a reflex hammer, not a finger or a stethoscope. Ideally, the baby is in a quiet alert state with the head in the midline. The head turned to one side can reinforce the tone and reflexes on that side. I usually start with the knee jerk because is the easiest to obtain. Take control of the leg with the hand under the knee and the leg at about a 90 degree angle at the knee. Then strike the patellar tendon with the reflex hammer using a pendular action rather a chopping action. | * Testing deep tendon reflexes is an important part of the newborn neurological exam.
