Deep tendon reflexes: the what, why, where, and how of tapping

Deep tendon reflexes demonstrate the homeostasis between the cerebral cortex and the spinal cord. When these reflexes are disrupted, hyperreflexia (disease induced) or hyporeflexia/areflexia (drug induced) occurs. Although nurses perform deep tendon reflex assessments regularly, it is difficult to incorporate theoretical principles in these assessments because of scant medical literature, a lack of nursing research, and time constraints in nursing programs. These conditions usually result in one-on-one training, causing reduced consistency. A comprehensive examination assists the clinician to apply theoretical principles, develop expert technique, and serve as a catalyst for clinical research.
