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.

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 …

2023年8月28日 · There are five primary deep tendon reflexes: biceps, brachioradialis, triceps, patellar, and ankle. Biceps Reflex. Brachioradialis Reflex. Triceps Reflex. Patellar Reflex (knee-jerk) Achilles Reflex (ankle-jerk)

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.

2023年8月12日 · Explore the physiology of deep tendon reflexes, their neural pathways, and clinical importance in neurological assessment. Understand the monosynaptic reflex arc, common reflexes, and their diagnostic significance.

2024年10月9日 · Deep tendon reflexes include the patellar, biceps, triceps, and brachioradialis reflex. They are an important indicator of intact peripheral nerves and spinal cord. Tests are done in routine neurological examinations, and to investigate …

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.

2024年12月1日 · Reflexes elicited by application of a stretch stimulus to either tendons or periosteum, or occasionally to bones, joints, fascia, or aponeurotic structures are usually referred to as muscle stretch or deep tendon reflexes. The reflex is caused by sudden muscle stretch, brought about by percussion of its tendon. Occasionally, the tendon is
