What is a DTR test?

A DTR (Deep Tendon Reflex) test is a neurological examination used to assess the integrity of the nervous system by evaluating reflexes. It involves tapping specific tendons with a reflex hammer to elicit involuntary muscle contractions, such as the knee-jerk response. The DTR test helps clinicians identify potential issues with the spinal cord, peripheral nerves, or neuromuscular junctions. Abnormal responses can indicate various neurological conditions.
