DTRs
Also written as: DTRs — deep tendon reflexes
Deep tendon reflexes, neurological examination components assessed during psychiatric evaluations to detect medication side effects or underlying neurological conditions.
Full Definition
Deep tendon reflexes (DTRs) are involuntary muscle contractions elicited by sudden stretching of tendons, routinely assessed during comprehensive psychiatric examinations. In behavioral health settings, DTR evaluation serves multiple clinical purposes including baseline neurological assessment, monitoring for extrapyramidal side effects of psychotropic medications, and identifying potential organic causes of psychiatric symptoms. Healthcare providers typically assess DTRs at standard anatomical locations including biceps, triceps, patellar, and Achilles reflexes using a standardized grading scale from 0 (absent) to 4+ (hyperactive with clonus). Abnormal DTR findings may indicate medication toxicity, movement disorders, or concurrent medical conditions requiring further evaluation or treatment modification.
Usage
Usage note: Use DTRs for the abbreviation; spell out 'deep tendon reflexes' on first mention in formal documents.
