Hoovers sign is the term used to describe the breathing pattern seen in copd patients in whom the lower costal margins of the chest wall draw inward with each inspiration.
<h3>What is Hoover's sign?</h3>
- Dr. Charles Franklin Hoover first described the Hoover's sign more than a century ago to distinguish between the biological and functional weakness of pyramidal origin.
- When one is uncertain about the type of hemiparesis at the bedside, this test—which is typically carried out in the lower limbs—is helpful.
- When requested to flex the hip of the normal leg against resistance, a subject with hemiparesis of an organic nature will not exert pressure on the examiner's hand placed beneath the heel on the affected side, however in hysterical weakness, heightened pressure will be felt on the examiner's hand.
- The crossed extensor reflex or the idea of synergistic contraction may have contributed to the development of this sign.
- Although it has a moderate sensitivity (63%) and a high specificity (100%) for identifying functional and organic paresis, there are several limitations that should be considered when evaluating a patient.

Answer:
Homeostasis can be defined as the natural mechanism of the body by which the internal temperature of the body is maintained.
This phenomenon is important for the normal metabolism and functioning of the body.
Whenever the body encounters any change in the outer environment, the body tries to cope up with the conditions by maintaining a proper internal temperature inside the body.
Example: shivering of body is a normal response during cold environment to maintain the internal temperature of the body.
