What does DTR mean?

DTR stands for Deep Tendon Reflexes, the reflexes tested by tapping a tendon, such as the knee-jerk reflex, to check the nervous system.

DTR stands for Deep Tendon Reflexes. These are the reflexes a clinician tests by tapping a tendon with a small hammer, causing the muscle to jerk. The most familiar example is the knee-jerk reflex, where tapping below the kneecap makes the lower leg kick out.

Testing deep tendon reflexes gives useful information about the nervous system. Reflexes are often graded on a scale, commonly from 0 (absent) to 4 (very brisk), with 2+ being normal. Reflexes that are too weak or too strong can point to problems with the nerves, spinal cord, or muscles.

DTRs are a routine part of the neurological examination and are recorded alongside other findings such as strength, sensation, and coordination.

When is DTR used?
