Imaging Dopamine Function and Its Impact on Outcome After Traumatic Brain Injury (TBI)

February 2, 2018 updated by: Baylor Research Institute

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Disability Rating Scale
Time Frame: Baseline, 1 week, 2 weeks, 3 weeks, 4 weeks
The primary outcome measure will be the change in Disability Rating Scale over 4 weeks. The Disability Rating Scale is a commonly used and reliable instrument for monitoring minor changes occurring throughout the course of a patient's recovery (Rappaport et al., 1982).
Baseline, 1 week, 2 weeks, 3 weeks, 4 weeks
