What is the normal range for deep tendon reflexes?

There are five primary deep tendon reflexes: bicep, brachioradialis, triceps, patellar, and ankle. Each reflex corresponds to a particular root and muscle and will evaluate the integrity of the root and associated nerve. NINDS grading of DTR ranges from 0 to 4. A normal response is grade 2 or 3.

What does deep tendon reflexes mean?

What causes loss of reflexes?

The most common cause of low reflex response is peripheral neuropathy. Diabetes, anemia, and vitamin deficiency are possible causes of absent reflexes. However, the conditions don’tcause brisk reflexes.

What is a deep tendon reflex rating?

Deep tendon reflexes are often rated according to the following scale: Deep tendon reflexes are normal if they are 1 +, 2 +, or 3 + unless they are asymmetric or there is a dramatic difference between the arms and the legs. Reflexes rated as 0, 4 +, or 5 + are usually considered abnormal.
