Agitation and Spasticity After Severe TBI
A 26-year-old man is 5 weeks post severe traumatic brain injury (GCS 5 at scene) from a fall. He has a tracheostomy (weaned to room air, speaking valve trials), a percutaneous feeding tube, and is now in inpatient rehabilitation. He is agitated, strikes at staff during transfers, and has intermittent extensor posturing of both legs with scissoring. He follows one-step commands inconsistently. His family wants him to "walk again soon" and asks why he is not yet in gait training. Current meds: baclofen 10 mg TID, trazodone at night, and levetiracetam.
1. How do you distinguish agitation from post-traumatic confusional state versus a medical cause, and what is your evaluation?
Read the worked answer
Agitation in this population is usually part of a post-traumatic confusional state (PTCS) - a transitional phase of recovery - but you must exclude reversible medical causes first.
Screen for medical contributors: pain, constipation, urinary retention or infection, occult fracture, medication effects (sedatives, anticholinergics), seizures, hydrocephalus, and sleep disruption. Review the medication list and consider simplifying.
Characterize the behavior: use a structured tool (e.g., Agitated Behavior Scale) and document triggers, timing, and whether agitation is worse with overstimulation. Inconsistent command following and posturing suggest impaired arousal and emerging cognition rather than pure psychiatric agitation.
Key reasoning: do not label this as "behavior" and do not escalate sedatives reflexively - sedation can prolong PTCS and mask a treatable cause. Coordinate with the team, obtain labs/imaging as indicated, and treat pain and bowel/bladder issues aggressively.
2. The family demands gait training now. How do you counsel them and structure the plan?

Acknowledge the goal and reframe the timeline: "Walking is the goal, but his brain is still in an early recovery phase. Pushing him too hard now can set him back." Explain PTCS in plain language.
Plan:
- Environment: low-stimulation setting, consistent staff, structured daily routine, and safety precautions for falls and impulsivity.
- Mobility: begin with supported standing and transfer training using a gait belt and two assistants, only when he can tolerate and is safe; progress to a walker or tilt table as tolerated.
- Therapy dosing: short, frequent sessions matched to his attention span; use familiar tasks and family presence to improve engagement.
- Behavioral approach: redirection rather than confrontation; identify and avoid triggers.
- Spasticity: address the extensor posturing with positioning, stretching, and medication review; consider botulinum toxin for focal lower-extremity spasticity if it interferes with hygiene or mobility.
- Family education: set measurable short-term goals (e.g., tolerating standing, participating in ADLs) so progress is visible.
3. What is your medication strategy for his spasticity and agitation, and what would make you reconsider it?
Read the worked answer
Spasticity: current baclofen 10 mg TID is reasonable; titrate based on function and comfort rather than tone alone. Add positioning and stretching. If focal extensor posturing limits care or mobility, consider botulinum toxin to hip adductors/gastrocnemius. Avoid abrupt baclofen changes.
Agitation: prefer nonpharmacologic management first. If medication is needed, choose agents that do not worsen cognition or arousal; avoid benzodiazepines and strongly anticholinergic drugs. Trazodone at night is reasonable for sleep. Reassess levetiracetam indication with neurology.
Reconsider if: new focal deficits, worsening arousal, fever, or a change in posturing suggest a new medical or neurosurgical problem; or if sedation is impairing participation in therapy. Coordinate with the physiatrist, pharmacist, and family throughout.
