The pattern of how blood sugar levels change during a typical 24-hour time period in persons with SCI is not known. There may be unknown factors that affect blood sugar levels. In order to find out that information, this study will involve continuously monitoring blood sugar over a 3-day period in a variety of persons with SCI. A non-invasive, wireless monitoring system will be attached to the abdomen. This system records blood sugar levels every 5 minutes. The information gathered from this observational study is vital to the understanding of how SCI alters the regulation of sugar levels in the blood and to the subsequent medical management of this population.
