Objective: To assess mortality, life expectancy, risk factors, and causes of death by age groups among persons who received inpatient traumatic brain injury (TBI) rehabilitation.
Design: Prospective cohort study.
Setting: The TBI Model Systems.
Objective: To compare the reliability of quadriceps-angle (Q-angle) measurements performed using a short-arm goniometer and a long-arm goniometer and to assess the accuracy of goniometer-based Q-angle measurements compared with anatomic Q angles derived from magnetic resonance imaging (MRI).
Design: An intra- and interobserver reliability study.
Setting: University hospital.
