TBI Model System

North Texas Traumatic Brain Injury Model System 

The North Texas Traumatic Brain Injury Model System (NTX-TBIMS) is a unique research and clinical collaborative between Baylor Scott and White Institute for Rehabilitation and UT Southwestern Medical Center. The NTX-TBIMS is one of 16 centers nationwide that was awarded a competitive grant by the National Institute of Disability, Independent Living, and Rehabilitation Research, due to its recognition as a national leader in TBI research and patient care.

Purpose of the TBI Model System
  • Deliver coordinated rehabilitation care to patients with TBI
  • Track the health of patients over their life-time to better understand and support their recovery
  • Conduct innovative research to improve patient outcomes
  • Participate in collaborative, multi-site research with other TBIMS centers across the country
  • Provide resources to patients and families

The North Texas TBI Model System has been funded since 2002 and provides the largest continuum of care to individuals with TBI in North Texas and surrounding states. This continuum includes emergency medical services, acute care, rehabilitation, and outpatient services with partners including Baylor Scott and White Health, Parkland Health and Hospital System, and John Peter Smith Hospital. The NTTBIMS pools the efforts and talents of caring individuals with expertise in areas such as rehabilitation, neuropsychology, and therapy at the leading medical institutions in North Texas with a long-standing history of collaboration.

Efficacy of an evidence-based weight-loss intervention post TBI.


Simon Driver, PhD (PI); Shannon Juengst, PhD (co-I)

Importance: Weight gain is common among people with TBI, with 70% of NTTBIMS patients being overweight/obese 10-years post injury. Weight gain greatly increases the risk of chronic diseases such as diabetes, metabolic syndrome, pulmonary and heart disease. Approaches to weight-loss are lacking, yet necessary, due to the unique physiological and cognitive needs of persons with TBI. There is evidence that interventions that improve physical activity and healthy eating behaviors concurrently offer greatest potential for weight-loss. The Group Lifestyle Balance (GLB) intervention is a 12-month, evidence-based weight-loss program that has been used extensively with the general population, but not with people with TBI.

Goal: We will conduct a randomized controlled trial to examine the efficacy of the GLB-TBI on primary (weight) and secondary outcomes (step count; waist circumference; blood pressure; HbA1c and lipid panel; functional measures; risk of diabetes; and quality of life) at 3, 6, and 12 months from baseline. We will also develop and use a mobile app to compliment the GLB-TBI and support participant’s weight-loss overtime.

Expected Outcome: Successful completion of this study will provide an evidence-based program, specifically tailored to meet the unique needs of people with TBI, which supports weight-loss and improves overall health and function. The intervention will be scalable to community agencies serving people with TBI, ensuring a national impact.
