What does reflex grade 3 indicate?

What does reflex grade 3 indicate?

• A. Absent reflex.
• B. Reflex only with reinforcement.
• C. Brisk contraction with movement.
• D. Very brisk contraction and increased movement indicating hyperreflexia.

Answer: (D)

Reflex grading shows how strongly a tendon tap elicits a muscle contraction. A grade of 3 is above normal, indicating a brisk, exaggerated response. The description of a very brisk contraction with increased movement fits this heightened reaction and is used to denote hyperreflexia. Hyperreflexia reflects increased excitability of the reflex arc, often due to reduced inhibitory control from the brain, and is commonly associated with upper motor neuron involvement. That’s why this option best matches what a grade 3 reflex represents.
