At stage two, the skin breaks open, wears away, or forms an ulcer, which is usually tender and painful. The sore expands into deeper layers of the skin. It may appear as a scrape, blister, or a shallow crater in the skin. At times this stage looks like a blister filled with clear liquid. Also at this stage some skin may be damaged beyond repair or may die.
Altered reciprocal inhibition <span>is caused by a tight agonist muscle decreasing the neural drive to its functional antagonist. Altered reciprocal inhibition changes the relationships of force pairs, resulting in equal superiority, resulting in further non-functioning patterns in movement, muscle control on a neurological level, and specifically malfunction of joints. </span>
