What are normal, expected reflex assessment findings in a neurological assessment?

• A. Absent reflexes everywhere
• B. Normal peripheral reflexes with symmetric responses and normal central reflexes (cough, gag, swallow)
• C. Hyperactive reflexes in all limbs
• D. Babinski reflex present in adults

Answer: (B)

Normal reflex findings reflect intact reflex arcs both peripherally and in the brainstem. In a healthy exam, deep tendon reflexes (like knee and ankle jerks) are present on both sides with similar strength, typically graded as 2+. In addition, central reflexes such as coughing, gag, and swallowing should be normal, indicating intact brainstem function. If reflexes were absent everywhere, that would point to diffuse peripheral nerve or muscle disease or acute spinal cord injury, which is not normal. Hyperactive reflexes in all limbs suggest upper motor neuron involvement, not a normal finding. A Babinski sign in an adult is abnormal and indicates corticospinal tract dysfunction. So the best description of normal findings is normal, symmetric peripheral reflexes with normal central reflexes.
