What is DTR Testing?

DTR (Deep Tendon Reflex) testing is a neurological examination technique used to assess the integrity of the reflex arc in the nervous system. It involves striking specific tendons with a reflex hammer to elicit an involuntary muscle contraction, which helps evaluate the function of the spinal cord and peripheral nerves. Commonly tested reflexes include the patellar (knee-jerk) and Achilles reflexes. Abnormal responses can indicate neurological disorders or issues with nerve function.
