Rehabilitation describes specialized healthcare dedicated to improving, maintaining or restoring physical strength, cognition and mobility with maximized results. Typically, rehabilitation helps people gain greater independence after illness, injury or surgery. Rehabilitation can also be explained as the process of helping an individual achieve the highest level of function, independence, and quality of life possible. Rehabilitation does not reverse or undo the damage caused by disease or trauma, but rather helps restore the individual to optimal health, functioning, and well-being.
