Injury Severity and Disability

What factors led to poor long-term functional outcomes in the TBI participant population?

• Less pre-injury education

• Lower Glasgow Coma Scale (GCS) scores

• Significantly longer post-traumatic amnesia (PTA)

  • Age and gender identified as potential contributing factors

What functional outcome measures were assessed in the TBI study (Ponsford et al., 2008)?

• Cognitive functioning

• Emotional regulation (anxiety, depression)

• Employment and social functioning

• Community integration

• Living skills and independence

How did education influence long-term outcomes after TBI?

• Higher pre-injury education was associated with:

  • Better employment outcomes

  • Improved social functioning

  • Greater community integration

• Skilled pre-injury employment predicted better living skills, relationships, and employment outcomes

What types of cognitive impairments were associated with poor functional outcome after TBI?

• Attention deficits

• Slowed information processing speed

• Memory impairments

• Executive dysfunction (planning, organization, self-control, time management)

How did TBI participants perform on cognitive tests compared to healthy controls?

• TBI participants scored lower across multiple cognitive domains

• Deficits persisted 10+ years post-injury

• Cognitive impairments were not solely explained by education level

Which cognitive abilities remained impaired 10 or more years after TBI?

• Working memory

• Processing speed

• Executive functions (planning, self-regulation, critical thinking, organization)

How was emotional regulation affected in individuals with TBI?

• TBI participants experienced greater emotional distress than controls

• Anxiety was especially evident in those with more severe injuries

• Emotional difficulties were not fully explained by education level

What was the relationship between depression and functional outcome after TBI?

Greater depression was not significantly associated with poorer functional outcome

What is known about motor impairment after TBI according to Kawabori et al.?

• Motor impairment occurs in approximately 30% of TBI survivors

• Over 30% of individuals with severe TBI had at least one neuromotor impairment

• Motor impairments were still present 2 years after inpatient rehabilitation

Why is TBI considered a chronic condition rather than an acute injury?

• Long-term consequences include:

  • Physical disability

  • Cognitive impairment

  • Emotional and psychological problems

• Functional deficits can persist for 10+ years post-injury, impacting independence and quality of life
