Traumatic Injuries:Traumatic Brain Injury
KNR 279
TRAUMATIC BRAIN INJURY
Insult to brain, not of degenerative or congenital nature, but caused by an external force that may produce a diminished or altered state of consciousness, which results in an impairment of cognitive or physical functioning
Open or closed injury Mild (concussion) to severe (coma)
INCIDENCES OF TBI
Over 2-5 million in US 1 injury every 15 seconds Many result in life long disability 56,000 killed annually Leading cause of death among
Americans under 45 Males 14-24 have highest rate
CAUSES OF TBI
50% Motor vehicle crashes 21% Falls 12% Violence 10% Sports & recreation 7% Other
Symptoms: Frontal Lobe/Foreheadwww.braininjury.com
Paralysis Problems sequencing for multi-step task Persistence of a single thought Inability to focus on task Mood changes/emotional liability Changes in personality Difficulty with problem solving Inability to express language
Parietal Lobe/ Near back & top of head
Inability to attend to more than 1 object at a time
Inability to name an object Inability to locate words for writing Problems reading Difficulty with drawing tasks Difficulty to distinguish left from right Difficulty with math Difficulty with eye-hand coordination
Occipital Lobes: Back of head
Defects in vision (visual field cuts) Difficulty locating objects in the
environment Problems identifying colors Difficulties with reading & writing Visual illusions (inaccurately seeing
objects)
Temporal Lobes: Side of head above ears
Difficulty recognizing faces Difficulty in understanding spoken words Short term memory loss Interference with long term memory Inability to categorize objects Right lobe can cause persistent talking Increased aggressive behavior
Brain stem: Deep within brain
Difficulty swallowing food & water Problems with balance & movement Dizziness & nausea Sleeping difficulties Decreased vital capacity in
breathing needed for speech
Cerebellum: Base of skull
Loss of ability to coordinate fine movements
Loss of ability to walk Tremors Slurred speech Inability to make rapid movements
EFFECTS OF TBI
Balance or equilibrium Behavior / emotion Cognitive Physical Seizures Speech / language
Glasgow Coma Scale
Ranchos Los Amigos ScaleLevel of Cognitive Functioning / Recovery
I = No response, comatose II = Generalized response,
nonpurposeful, inconsistent III = Localized response,
inconsistent reaction to specific stimuli
IV = Confused, agitated, nonpurposeful behavior, inability to process information
Ranchos Los Amigos ScaleLevel of Cognitive Functioning / Recovery
V = Confused, inappropriate, nonagitated behavior, alert, highly distractible, responds to simple commands
VI = Confused but appropriate behavior, goal-directed, uses external input for direction
Ranchos Los Amigos ScaleLevel of Cognitive Functioning / Recovery
VII = Automatic, appropriate behavior, robot like compliance with routine, shallow recall, increased awareness of others
VIII = Purposeful, appropriate behavior, alert, oriented, independent functioning
Recommended TR Interventions
I, II, III = Sensory stimulation, passive stretching, art, movement to music, cognitive retraining, reality orientation
IV, V, VI = Aquatic therapy, expressive arts, leisure education, horticulture, behavior management, stretching & flexibility exercises, table & board games
Carter, Van Andel, & Robb, 2003
Recommended TR Interventions
VII, VIII = Computer games, Community integration, expressive arts, social skills training
Carter, Van Andel, & Robb, 2003
Considerations/Accommodations
Decrease distractions in environment Provide repetition & consistency Demonstrate new tasks & provide
examples Help with planning Behavior management Guidance with appropriate behavior in
social situations May not remember that just asked
question
Considerations/Accommodations
Structure Start with simple tasks & small
steps Give clear, concrete directions Supervise, may not know own
limitations
