You’re treating a 24-year-old who was in a car accident three months ago. They can walk, but their balance is off, they fatigue easily, and they struggle to follow your instructions. This is traumatic brain injury (TBI)—and as a PT, you’re not just treating the brain; you’re treating the whole person.
What is Traumatic Brain Injury (TBI)?
Traumatic brain injury (TBI) is a disruption in normal brain function caused by an external mechanical force—a blow, jolt, or penetrating injury to the head. It’s classified by severity using the Glasgow Coma Scale (GCS): mild (13–15), moderate (9–12), and severe (3–8). You’ll also encounter terms like diffuse axonal injury, contusions, and subdural hematomas, each presenting with vastly different functional deficits.
Why TBI Matters in Physical Therapy Practice
TBI is a leading cause of long-term disability, and PTs are central to the rehabilitation team. The injury impacts motor control, balance, cognition, vision, and endurance—all of which directly shape your Plan of Care (POC). Your interventions must be tailored to the patient’s cognitive capacity and safety awareness, not just their physical impairments. Prognosis varies widely, making reassessment at every stage essential.
What You’ll See in the Clinic
Presentation is highly variable. You may observe hemiparesis, ataxia, spasticity, or apraxia. Gait is often slowed with reduced step length, and patients report headaches, dizziness, and fatigue. They may become irritable or confused when overstimulated.
“Patient is a 32-year-old male, s/p moderate TBI (MVA, 2 months ago). Ambulating 100 feet with a front-wheeled walker; requires verbal cues for safety and sequencing. Berg Balance Scale 38/56. Cognitive fatigue noted after 20 minutes of therapy. Plan: progress standing balance with dual-task training, grade gait endurance, and monitor for overstimulation.”
Common Pitfall & Pro Tip
⚠️ Pitfall: Pushing the patient too hard, too fast. Cognitive fatigue and sensory overload can cause setbacks. Watch for irritability, headache, or decreased responsiveness—these are your cues to back off.
💡 Pro Tip: Use structured, predictable sessions with clear starts and ends. Break tasks into single steps and use external cues like visual targets or verbal checklists. This reduces cognitive load and builds confidence.
Memory Aid for TBI
Think “STOP” — Safety first (fall risk), Task breakdown (one step at a time), Observe for fatigue (cognitive and physical), Progress slowly (reassess often). This keeps sessions effective without overloading the patient.
NPTE Connection
Expect TBI questions involving GCS scoring, Rancho Los Amigos Levels of Cognitive Functioning, and matching interventions to specific cognitive stages—especially safety precautions and contraindications.
Related Physical Therapy Concepts
TBI connects directly to Stroke Rehabilitation (similar motor deficits, different etiology), Cerebellar Ataxia (balance and coordination issues), and Vestibular Rehabilitation (dizziness and gaze instability). You’ll also apply principles from Motor Learning Theory to structure practice and feedback.
