SCI can be divided into two types of injury - complete and incomplete. A complete injury means that there is no function below the level of the injury; no sensation and no voluntary movement. Both sides of the body are equally affected. An incomplete injury means that there is some functioning below the primary level of the injury. A person with an incomplete injury may be able to move one limb more than another, may be able to feel parts of the body that cannot be moved, or may have more functioning on one side of the body than the other. With the advances in acute treatment of SCI, incomplete injuries are becoming more common. webmaster@thescizone.com (Super Admin) Tue, 10 Jul 2007 00:00:00 -0400 http://www.thescizone.com/questions/articles/30/1/Has-the-incidence-of-SCI-changed-in-recent-years/1.html We don't know, because there haven't been any national studies of incidence in the past 15 years. The statewide registries will eventually be able to answer this question after they have been in existence a while longer. webmaster@thescizone.com (Super Admin) Thu, 22 Sep 2005 00:00:00 -0400 http://www.thescizone.com/questions/articles/17/1/Whats-leading-cause-of-death/1.html In years past, the leading cause of death among persons with SCI was renal failure. Today, however, significant advances in urologic management have resulted in dramatic shifts in the leading causes of death. Persons enrolled in the National SCI Database since its inception in 1973 have now been followed for 27 years after injury. During that time, the causes of death that appear to have the greatest impact on reduced life expectancy for this population are pneumonia, pulmonary emboli and septicemia. webmaster@thescizone.com (Super Admin) Tue, 23 Aug 2005 00:00:00 -0400 http://www.thescizone.com/questions/articles/37/1/Causes-of-Spinal-Cord-Injury/1.html The most common causes of spinal cord injury are car and other motor vehicle collisions (54.7%), falls (17.7%), and other medical conditions and sports injuries (27.6%). The injury is usually caused by sudden impact, which crushes the spine and cord. webmaster@thescizone.com (Super Admin) Sun, 17 Jul 2005 00:00:00 -0400 http://www.thescizone.com/questions/articles/76/1/What-Gender/1.html Overall, 81.6% of all persons in the national database are male. Although this four-to-one male to female ratio has varied little throughout the 25 years of the Model Systems data collection, since 1990, the percentage of males has decreased to 80.5% (from 81.8% in the 1970's). webmaster@thescizone.com (Super Admin) Mon, 13 Jun 2005 00:00:00 -0400 http://www.thescizone.com/questions/articles/15/1/Whats-the-age-SCI-happen/1.html SCI primarily affects young adults. Fifty-five percent of SCIs occur among persons in the 16 to 30 year age group, and the average age at injury is 32.1 years. Since 1973 there has been an increase in the mean age at time of injury. Those who were injured before 1979 had a mean age of 28.6 while those injured after 1990 had a mean age of 35.3 years. Another trend is an increase in the proportion of those who were at least 61 years of age at injury. In the 1970's persons older than 60 years of age at injury comprised 4.7% of the database. Since 1990 this has increased to 10%. This trend is not surprising since the median age of the general population has increased from 27.9 years to 35.3 years during the same time period. webmaster@thescizone.com (Super Admin) Wed, 23 Mar 2005 00:00:00 -0500 http://www.thescizone.com/questions/articles/57/1/Does-demylination-STOP-conduction-or-SLOW-DOWN-conduction/1.html Axons that are demyelinated cannot conduct as well. Cells called oligodendroglial cells form myelin around segments of axons. Each segment may be as long as several millimeters in length. Also, the axons are usually partially remyelinated after injury. The conduction deficit depends on the extent of demyelination and remyelination. Demyelination may stop or slow down conduction. More important, it may prevent the conduction of a train of impulses. Axonal information is often coded in bursts of action potentials. Demyelinated axons may be able to support one impulse but not a rapid train of impulses. Demyelination can also reduce the safety factor of conduction. In other words, an impulse has a smaller chance of getting through a demyelinated zone. Demyelination or abnormal myelination reduces the amount of information that an axon can pass through. webmaster@thescizone.com (Super Admin) Sat, 16 Oct 2004 00:00:00 -0400 http://www.thescizone.com/questions/articles/31/1/How-many-people-are-alive-today-in-the-US-with-SCI/1.html Estimates vary, but the generally accepted range is between 183,000 and 230,000 persons are alive today in the U.S. with SCI. webmaster@thescizone.com (Super Admin) Sat, 02 Oct 2004 00:00:00 -0400 http://www.thescizone.com/questions/articles/18/1/What-ethnic-groups-have-SCI/1.html  A significant trend over time has been observed in the racial distribution of persons in the Model System database. Among persons injured between 1973 and 1978, 77.5% of persons in the database were Caucasian, 13.5% were African-American, 5.7% were Hispanic, 2% were American Indian and 0.8% were Asian. However, among those injured since 1990 only 59.1% were Caucasian, while 27.6% were African-American, 7.7% were Hispanic, 0.4% were American Indian, 2.1% were Asian (and 0.5% were unknown and 2.5% were unclassified). webmaster@thescizone.com (Super Admin) Thu, 23 Sep 2004 00:00:00 -0400 http://www.thescizone.com/questions/articles/29/1/What-are-the-leading-causes-of-SCI/1.html  Motor vehicle crashes rank 1st at 38.5% followed by acts of violence at 24.5%; falls at 21.8%; sports at 7.2% and all others at 7.9%. These figures are for all injuries reported to the National Database since 1990. The percentage of cases due to acts of violence and falls have increased steadily since 1973. The percentage of cases due to motor vehicle crashes and sports has been falling. webmaster@thescizone.com (Super Admin) Mon, 20 Sep 2004 00:00:00 -0400
