Causes Of Deep Tendon Reflex Decrease
Deep tendon reflex: Dtr or deep tendon reflex is a test done on physical exam to evaluate specific nerve function. Certain nerves like cervical and lumber spinal nerves control certain reflexes and when absent can indicate a problem with that nerve. Like the patellar or knee reflex can indicate a spinal nerve problem or herniated disc.

See below: A deep tendon reflex reflects the function of a part of the nervous system that travels to and from the spinal cord. It is also influenced by the brain. It is involuntary. Some people have brisker reflexes than others and it is completely normal. Some conditions can cause brisker reflexes like an overactive thyroid or certain nervous system conditions like injury to the brain or spinal cord.
Is a change in your deep tendon reflex history an ominous sign? Like going from 2+ to 4+ on a scale that goes to 5+
That is not: A very sensitive test, depends on how performed and your mental state at that time. Would be significant if not present or you had other signs to associate with
Spastic muscles: Muscles get "tetanic" when there isn't enough calcium. They contract more easily because the decreased calcium affects contractility of muscle fibers.
A little learning...: ... Is a dangerous thing. People's deep tendon reflexes are widely variable. A brain tumor that makes a DTR brisker will always (no exceptions) do so asymmetrically, and will have some other symptom (headache, personality change, nausea, altered walk). Some folks, including one of my neurology attendings, have no dtr's, and they're normal unless even a lay person can see they aren't.See 1 more doctor answer
Big jerks in all of my deep tendon reflex test. I have numbness and tingling and postural tremors. Normal MRI of braim and spine. Low B12 and sjogrens
What happens to the patellar tendon reflex after running on the spot and why does this happen? Please help, this is urgent
Patellar reflex: The patellar tendon reflex is an involuntary reflex arc that occurs in response to rapid stretching of the tendon. When the tendon is tapped with a reflex hammer, involuntary stimulation of the quadriceps muscle (e.g., knee extension) is produced. Running and other exercises that promote fatiguability of the quad muscles can blunt, but typically cannot eliminate, the effect of the reflex itself.See 1 more doctor answer
Bursitis: Popping of a tendon is usually either chronic dislocating or the tendon rubbing an adjacent structure. Since the achilles really can't dislocate, it is likely rubbing on a small, fluid-filled sac underneath called the retrocalcaneal bursa. If it is painful and avoiding irritating shoes doesn't improve things, see a podiatrist. Sometimes a steroid injection can help.
0-4: Deep tendon reflexes, of which the knee-jerk is the best known, are spinal reflexes triggered by hitting certain tendons. Triceps, biceps, patellar (knee) and ankle are the most commonly tested and are graded 0-4 as follows: 0-absent 1-small reaction 2=normal 3=brisk 4=clonic (continuous jerking) clinical context and symmetry more important than the actual reflex grade though.
Irritation: If the shoes rubs on the tendon it can irritate the skin and create an itching feeling.See 1 more doctor answer
Tendonitis usually: The attachment of the tendons or ligaments to bone can get inflamed - insertional tendonitis, assuming no fractures on xrays. Usually this results from somewhat tight quadriceps (thigh muscles), and a course of stretching with antiinflammatories helps. If this is not an isolated site of the inflammation, with other places in the body inflamed as well, a rheumatological workup would be in order.
Weak tendon sheath: Degenerative tears in the achilles are caused by a weak sheath that covers the tendon itself. Since the sheath protects the tendon and gives it it's nourishment, if it is congenitally weaker it will create tears. This is also made worse by Cipro (ciprofloxacin) or levoquin antibiotics and some statin drugs. A syrinx is a cavity in the spinal cord (short for syringomyelia), not in the achilles.See 1 more doctor answer
