DTR assessment
Pronunciation: dee-tee-are assessment
Also written as: DTR — Deep Tendon Reflex assessment
Deep tendon reflex evaluation performed to monitor for neurological side effects of psychiatric medications, particularly lithium and antipsychotics.
Full Definition
Deep tendon reflex (DTR) assessment is a neurological examination component routinely performed in psychiatric settings to detect medication-induced movement disorders and neurological complications. This assessment involves testing reflexes at the knees, ankles, biceps, and triceps using a reflex hammer. In psychiatry clinics, DTR assessments are particularly important for patients on lithium therapy, as diminished reflexes may indicate lithium toxicity. The assessment is also used to establish baseline neurological function before initiating antipsychotic medications and to monitor for the development of extrapyramidal symptoms. Documentation of DTR findings is essential for treatment planning and liability protection.
Usage
Usage note: Always specify 'DTR assessment' rather than just 'DTR' to avoid confusion with other medical abbreviations. Document specific reflex grades (0-4+ scale) in clinical notes.
