What does it mean when you have no reflex in your arm?

Usually, absent reflexes are caused by an issue with the nerves in the tendon and muscle. You may have other muscle symptoms along with areflexia, like weakness, twitching, or atrophy.

What is a positive reflex test?

Reflex Tests refer to the additional testing, which occurs when initial test results are positive or outside of normal parameters and indicate that a second related test (second level) is medically appropriate.

What does the bicep reflex test assess?

Unsourced material may be challenged and removed. Biceps reflex is a reflex test that examines the function of the C5 reflex arc and the C6 reflex arc. The test is performed by using a tendon hammer to quickly depress the biceps brachii tendon as it passes through the cubital fossa.

Why do doctors test your reflexes?

If you think you have brisk reflexes you can ask your doctor for a reflex test. This test helps determine how effective your nervous system is by assessing the reaction between your motor pathways and sensory responses.

What is normal reflex?

The normal reflex response is flexion of the great toe. An abnormal response is slower and consists of extension of the great toe with fanning of the other toes and often knee and hip flexion. This reaction is of spinal reflex origin and indicates spinal disinhibition due to an upper motor neuron lesion.

Why is reflex testing important?

Reflex testing contributes to accurate bedside diagnosis in many cases of neuromuscular disease, providing localising diagnostic information that cannot be obtained by any other method (including clinical neurophysiological and neuroradiological investigations).

Why do doctors check for reflexes?

What is a abnormal reflex?

Definition. Any anomaly of a reflex, i.e., of an automatic response mediated by the nervous system (a reflex does not need the intervention of conscious thought to occur). [

What are doctors looking for when they test your reflexes?

If you think you have brisk reflexes you can ask your doctor for a reflex test. This test helps determine how effective your nervous system is by assessing the reaction between your motor pathways and sensory responses. During the test, your doctor may tap your knees, biceps, fingers, and ankles.

What are abnormal reflexes?

What diseases affect reflexes?

Causes of Reflex Sympathetic Dystrophy Syndrome

• certain heart diseases, including myocardial infarction.
• cervical spine or spinal cord disorders.
• lesions on the brain.
• certain infections.
• invasive surgery.
• repetitive motion disorders leading to such ailments as carpal tunnel syndrome.

What can cause slow reflexes?

Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. And the parts of the brain involved in motor control lose cells over time.
