DTRS Fda Abbreviation

Deep Tendon Reflexes

Deep Tendon Reflexes (DTRs) are a type of reflex that tests the function of the nervous system. These reflexes are involuntary muscle contractions that occur in response to a sudden stretch or tap on a specific tendon. DTRs are important for maintaining posture, balance, and coordination, and are controlled by the nervous system.

During a DTR test, a healthcare provider will use a reflex hammer to tap the tendon just below the muscle belly. The reflex response is graded on a scale of 0 to 4, with 0 indicating no reflex response and 4 indicating a very brisk reflex response. The most commonly tested DTRs are the knee-jerk reflex and the ankle reflex.
