The DTR score for a normal knee-jerk reflex is which number?

Explanation:
A normal deep tendon reflex is graded as 2+. Reflexes are scored on a 0 to 4+ scale: 0 means no response, 1+ is diminished, 2+ is normal, 3+ is brisk, and 4+ is hyperactive with clonus. The knee-jerk (patellar) reflex should produce a clear, brisk contraction of the quadriceps without being exaggerated. If the reflex is 2+, it indicates a normal, symmetric response, appropriate for age and individual variation. Scores at the extremes (0 or 4+) or even 3+ can suggest abnormalities such as nerve damage or upper motor neuron involvement, while 1+ would indicate a weaker-than-normal response.
