Hyperactive Deep Tendon Reflexes (Overview)

Hyperactive deep tendon reflexes are a clinical finding in which the reflexes of the major joints in the body are tested by a physician (such as tapping beneath the knee) and are found to be produce more of a reflex response in speed or amount of movement.

What are hyperactive deep tendon reflexes?

See below: A DTR is a brisk contraction of a muscle in response to a sudden stretch induced by a sharp tap by a finger or rubber hammer on the tendon of insertion of the muscle. Absence of the reflex may be caused by damage to the muscle, peripheral nerve, nerve roots, or spinal cord at that level. A hyperactive reflex may indicate disease of the pyramidal tract above the level of the reflex arc being tested. ...Read more

What are deep tendon reflexes and how they are graded?

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. ...Read more

What is the definition or description of: deep tendon reflex?

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. ...Read more

I need your help please? What makes me kick so hard when they test deep tendon reflex?

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. ...Read more

My son has brisk deep tendon reflex and thinks he has brain cancer. Please help im his mother?

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. ...Read more

What happens to the patellar tendon reflex after running on the spot and why does this happen? Please help, this is urgent

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. ...Read more

How does a hyperactive stretch reflex (due to spinal cord injury) result in clonus?

Brakes are released: The quick answer: the brain/spinal cord send electrical fibers to control the muscles. When the fibers are severed, the muscles "do their own thing", unregulated.

In fingers how deep below surface is fat tissue layer? &how deep are nerves/tendons?

Depends: The thickness of the fat layer varies greatly between different parts of the body and in different people. The fat layer in hands and feet is usually quite thin while fat on the abdomen can be several inches thick. Obese people may have several inches of fat while athletic people may have nearly none. Nerves are present in the skin and below the fat but tendons are only present underneath the fat. ...Read more

My md has recently written in my physical exam, deep tendon response is sluggish. What does it mean and what are the implications? I take 500mgmetfor

Many things: There are metabolic and neurologic causes of sluggish reflexes. Ask him/her what was meant and what sort of followup is necessary. If you are taking metformin for diabetes ask what other neurological tests were done and whether you have peripheral diabetic neuropathy. ...Read more

Not sure if I have a palpable supraclavicular lymph node or not. Should be able to feel tissue and tendons deep in hollow above collar bone?

Not sure if I have a palpable supraclavicular lymph node or not. Should be able to feel tissue and tendons deep in hollow above collar bone?

Probably normal: People can easily feel muscles, tendons, and other irregularities if they try, this site or elsewhere. Anything you have to work hard to decide if it's abnormal probably is not. Repeated poking can cause tenderness and swelling -- and what was previously normal becomes nonspecifically inflamed and that much harder to diagnose. If you remain concerned, see a doctor. In the meantime, hands off. ...Read more

Deep bruise from a fall on my right Achilles tendon 8wks ago. Still swollen, hurts to touch and is numb. Doc hasn't done tests. What do I do now?

Second opinion: It would be unusual for a simple bruise to last that long. It's possible you may have a partially torn achilles
tendon. Have a podiatrist evaluate the area. He will likely want to get an MRI to check for tendon damage. ...Read more
