Deep tendon reflexes are monosynaptic stretch reflexes initiated by sudden stretching of a muscle sending impulses from the muscle spindle afferents (intrafusal fibers), which synapse directly with the motor neurons leading to contraction of the extrafusal muscle. Superficial reflexes. Deep tendon reflexes. Type.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 theDeep tendon reflexes are involuntary muscle contractions that occur in response to a sudden stretch of a muscle. They are controlled by the nervous system and are commonly tested using a reflex hammer. During pregnancy, the deep tendon reflexes can change due to a combination of hormonal and mechanical factors.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. 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. Abstract Objective: The deep tendon reflex (DTR) is routinely used by …Clonus is a rhythmic, oscillating, stretch reflex. The cause of the oscillations are related to lesions in upper motor neurons and is generally accompanied by hyperreflexia. Therefore, clonus is used as part of the neurological physical exam to assess the status of a patient’s nervous system. It is also used in prognostic evaluation of seizures in certain drug overdoses, and therefore ... The deep tendon reflex examination is part of the neuro assessment for the nursing head to toe assessment. This assessment is usually conducted during the head-to-toe nursing assessment.
