Estimates of the precision of total and regional soft tissue body composition by dual-energy X-ray absorptiometry in persons with chronic spinal cord injury

In both the clinical and research setting, the total body dual energy X-ray absorptiometry (DXA) scan is widely employed to measure longitudinal changes in fat tissue mass and lean tissue mass of the total body and regional areas in persons with spinal cord injury (SCI). Knowledge of the precision error is essential due to less than optimal limb positioning (i.e., joint contracture and spasticity) that could confound the reliability of body composition measurements.
