A DTR comprises of a reflex arc, which is a neural pathway that ... Deep Tendon Reflexes: A Study Of Quantitative Methods. The tendon tap used by clinicians to elicit DTRs and the reflex response elicited were quantified, and a systematic method for DTR testing was proposed, which fell into 3 ranges: 0–20 Nt for hyperreflexia, 21–50 NT for normoreflexia, and >50 N t for hyporeflexic.in understanding the reflex activity from his vast physiologic investigations in the late 1800s to early 1900s (1, 2). Muscle Stretch Reflexes or Deep Tendon Reflexes In 1859, Silas Weir Mitchell was the first person to appreciate the response elicited by percussed muscles with a hammer. The term ‘reflex’ was not used at that time and theHealthcare providers use the deep tendon reflex (DTR) examination to check for hyporeflexia or hyperreflexia as part of a neurological exam. The best known of the …The principal deep tendon reflexes and their corresponding spinal roots are listed in Table 2-3. Severe hyper-reflexia results in clonus— repeated rhythmic contraction elicited by striking a tendon or dorsiflexing the ankle. By convention, deep tendon reflexes are graded on a scale of 0 to 5 (Box 2-3). 2. Plantar reflex The deep tendon reflex is sometimes called the stretch reflex or myotatic reflex because of the stretch action and the muscle response involved. Some authors argue that they are not the same reflex. They believe the tendon reflex occurs after the tendon's active stretching when it is tapped with the hammer.
