Which grade reflects a mid-range normal response in DTR testing?

  1. DTR Grade 1

  2. DTR Grade 2

  3. DTR Grade 3

  4. DTR Grade 4

The correct answer is: DTR Grade 2

DTR Grade 2 indicates a mid-range normal response in deep tendon reflex (DTR) testing. This grading scale typically ranges from 0 to 4, with 0 signifying no reflex response, 1 representing a diminished reflex, 2 indicating a normal and expected reflex, 3 showing an exaggerated reflex, and 4 reflecting a very brisk reflex response often associated with clonus. A DTR Grade of 2 is considered optimal for a healthy individual, representing an intact reflex arc and normal nervous system functioning. This finding suggests that the spinal cord's reflex pathways are intact, providing assurance that no underlying neurological deficit is present. The mid-scale nature of this grade helps clinicians assess the adequacy of neurological function in patients, guiding further investigation if necessary.
