What does exaggerated knee reflex indicate?

On the other hand, multiple oscillation of the leg (pendular reflex) following the tap may be a sign of cerebellar diseases.

Exaggerated (brisk) deep tendon reflexes such as this can be found in upper motor neuron lesions, hyperthyroidism, anxiety or nervousness..

Is Hyperreflexia a sign of MS?

Motor weakness often is accompanied by upper motor neuron signs, such as mild spasticity, hyperreflexia, and pathologic signs. The most common initial presentation is paraparesis, but weakness can be also found in just one extremity (monoparesis) or all four extremities (quadriparesis).

What will happen if we don’t have reflex action?

If the reaction is exaggerated or absent, it may indicate a damage to the central nervous system. Most reflexes go completely unnoticed because they don’t involve a visible and sudden movement. Body functions such as digestion or blood pressure, for example, are all regulated by reflexes.

Who controls reflex?

Reflex actions are under the control of the spinal cord.

What do hyperactive reflexes indicate?

Hyperreflexia refers to hyperactive or repeating (clonic) reflexes. These usually indicate an interruption of corticospinal and other descending pathways that influence the reflex arc due to a suprasegmental lesion, that is, a lesion above the level of the spinal reflex pathways.

What was your first signs of MS?

What causes exaggerated reflexes?

Hyperthyroidism: This condition can cause too much thyroid hormone to be released in your body. This can cause the muscle fibers to break down too quickly, causing brisk reflexes. Anxiety: The adrenaline rushes caused by anxiety can cause your reflexes to be more responsive than normal.

What is the fastest reflex in the human body?

There are many various reflexes that can occur simultaneously during a startle response. The fastest reflex recorded in humans happens within the masseter muscle or jaw muscle. The reflex was measured by electromyography which records the electrical activity during movement of the muscles.

What is a natural reflex?

A reflex, or reflex action, is an involuntary and nearly instantaneous movement in response to a stimulus. … A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain.

What do reflexes show?

Reflex tests are performed as part of a neurological exam, either a mini-exam done to quickly confirm integrity of the spinal cord or a more complete exam performed to diagnose the presence and location of spinal cord injury or neuromuscular disease. Deep tendon reflexes are responses to muscle stretch.
