What does reflex grade 1 indicate?

• A. No response even with reinforcement.
• B. Reflex only elicited with reinforcement such as voluntary muscle contraction indicating diminished response.
• C. Brisk contraction without exaggeration.
• D. Very brisk contraction with movement.

Answer: (B)

Reflex grading measures how easily the reflex arc responds. A grade 1 reflex is diminished and not easily elicited on its own; it only appears when you engage reinforcement, such as having the person contract a muscle or use a maneuver that increases reflex excitability. This shows hypoactive reflexes—not completely absent, but noticeably reduced. For context, a normal reflex is typically 2+, brisk contractions without effort; absent reflexes are 0; brisk, exaggerated responses with movement are 4+. So a 1+ finding sits between absent and normal, indicating a mild decrease in reflex responsiveness that can be unmasked with reinforcement.
