Reflex Exam (Deep Tendon Reflexes) The reflex exam is fundamental to the neurological exam and important to locating upper versus lower motor neuron lesions. There are five deep tendon reflexes and a number of superficial and visceral reflexes covered here.

By convention the deep tendon reflexes are graded as follows: Whether the 1 + and 3 + responses are normal depends on what they were previously, that is, the patient's reflex history; what the other reflexes are; and analysis of associated findings such as muscle tone, muscle strength, or other evidence of disease.

2023年8月28日 · Deep tendon reflexes or, more accurately, the 'muscle stretch reflex' can aid in evaluating neurologic disease affecting afferent nerves, spinal cord synaptic connections, motor nerves, and descending motor pathways.

2023年7月24日 · This article will focus on the “deep tendon reflexes” which are more appropriately named — and will be referred to herein — as muscle stretch reflexes (MSR). MSR grading is based on a clinician’s subjective evaluation of amplitude, with a …

2023年5月26日 · Deep tendon reflexes are involuntary muscle contractions that occur when a specific tendon is stretched. They are also known as myotatic reflexes and are part of the neurological assessment. The spinal cord and the brain control these reflexes.

2024年8月28日 · Deep Tendon Reflexes (DTRs) are involuntary, automatic responses to a stimulus applied to a tendon, typically involving the muscle it is connected to. These reflexes are essential for assessing the integrity of the nervous system, particularly the …

The deep tendon reflex (DTR), also known as a myotatic reflex, is a sequence of lengthening, contraction, and relaxation of a group of muscles. A DTR comprises of a reflex arc, which is a neural pathway that controls a reflex. The reflex arc is made up of five components:

2015年11月19日 · With deep reflexes, an internal structure (i.e., a tendon) stretches and stimulates the receptors in the muscle group. The aroused receptors initiate the reflex arc, causing the muscle to move. Deep reflexes include patellar, Achilles, plantar, triceps, and …

2023年7月16日 · Deep tendon reflexes are involuntary muscle contractions that occur in response to the stretching of a tendon. These reflexes provide important information about the integrity of the nervous system and help healthcare professionals assess …
