Well it appears as though there have been developments in the use of cord blood to treat cerebral palsy, or CP. Since January 2010, the U.S. Food and Drug Administration (FDA) has approved 2 different clinical trials to investigate the effect of cord blood in patients with CP. CP is a disorder that affects a person’s ability to move and maintain balance and posture. It is most often caused by a lack of oxygen to the brain, usually before or during birth, that results in damage to the portion of the brain that controls muscle tone.
