What is the normal deep tendon reflex grade in a healthy adult?

• A. 0
• B. 2+
• C. 1+
• D. 3+

Answer: (B)

Deep tendon reflexes are graded on a 0 to 4+ scale, and a normal response in a healthy adult is 2+. This indicates an average, expected reflex that is present and felt with a standard strength. Reflexes should be roughly equal on both sides. A score of 0 or 1+ suggests hyporeflexia, which can point to peripheral nerve or spinal root issues, muscle disease, or acute conditions. A score of 3+ or 4+ indicates hyperreflexia, which can be normal for some individuals but often signals upper motor neuron involvement when excessive or asymmetric. So, 2+ best represents the typical normal reflex in a healthy adult.
