Decreased reflexes present in lower motor neuron lesions, including nerve root lesions with radiculopathy and peripheral nerve lesions. Diabetes and hypothyroidism slow down the response of the DTR.
If absent when initially tested, the response can be elicited with repetitive tapping of the tendon; however, this maneuver sometimes causes extinguishment of the reflex. Muscle disease may cause the reflex to become diminished as the muscle fiber can not respond adequately.
A patient with a spinal cord injury presenting spinal shock can have hyporeflexia. Cerebellar disease can also produce hyporeflexia. If the reflexes decrease bilaterally, it is often a normal finding.
If the reflex is absent, other findings are usually present secondary to the lower motor neuron disease. They include muscle atrophy, weakness, and sometimes fasciculations. If it is an isolated reflex deficit, it is most commonly the result of a root lesion, a peripheral nerve injury or entrapment, or a mononeuropathy.
Bilateral absent ankle jerk usually indicates a peripheral neuropathy, but a cauda equina syndrome can also produce it. Specific peripheral nerve injuries can produce decreased or absent DTR. Musculocutaneous nerve injury will have the biceps reflex affected. A radial nerve injury can have the triceps or the brachioradialis reflex affected depending on the anatomical area of damage in the nerve. Femoral nerve lesions will affect the patellar reflex, and tibial nerve lesions will affect the ankle reflex.

As a nurse and nursing student, you will learn how to assess the deep tendon reflexes. The deep tendon reflex examination is part of the neuro assessment.
This assessment is usually conducted during the head-to-toe nursing assessment. This acronym is the equivalent of having 'the chat' about where your relationship is heading, meaning ' define the relationship. Otherwise known as bread-crumbing, this is when someone you've been dating stops agreeing to meet in person, but continues to contact you over message and social media.
You install it behind your firewall so that you can securely store and manage the Docker images you use in your applications. Nutrition and dietetics technicians, registered NDTRs are educated and trained at the technical level of nutrition and dietetics practice for the delivery of safe, culturally competent, quality food and nutrition services. NDTRs are an integral part of healthcare and food service management teams.
Defining the relationship — otherwise known as DTR — is a scary thing. Clonus is a sign of certain neurological conditions, particularly associated with upper motor neuron lesions involving descending motor pathways, and in many cases is, accompanied by spasticity another form of hyperexcitability. Tendon reflex tests are used to determine the integrity of the spinal cord and peripheral nervous system, and they can be used to determine the presence of a neuromuscular disease.
In a normal test, your knee will extend and lift your foot a little. A decreased or absent reflex may mean that there is compression in the L2, L3, or L4 region. Achilles tendon reflex. A decreased or absent reflex may mean that there is compression in the S1 region. As a nurse and nursing student, you will learn how to assess the deep tendon reflexes. The deep tendon reflex examination is part of the neuro assessment. This assessment is usually conducted during the head-to-toe nursing assessment.
What does the term DTR stand for? DTR is an acronym that means define the relationship. Used in chat and texting, it implies a critical point in a relationship in which one person wants clear answers from the other.
What is DTR work? Payroll system is based on the employee timekeeping: the employee's salary will be based with the hours they have worked for. Online DTR Software is an employee timekeeping clock and a managerial device. What does DTR mean sexually? What is clonus a sign of? Clonus is a series of involuntary, rhythmic, muscular contractions and relaxations. Clonus is a sign of certain neurological conditions, particularly associated with upper motor neuron lesions involving descending motor pathways, and in many cases is, accompanied by spasticity another form of hyperexcitability.
