Rehabilitation Interventions, Functional Recovery, and Assistive Technology
Dose, task, and technology
Rehabilitation after brain injury is interdisciplinary: physiatry leads, with PT, OT, speech-language pathology, neuropsychology, nursing, social work, and vocational services. Recovery is driven by intensity and specificity of practice, so early mobilization and task-specific, repetitive training (gait, reach, ADLs) form the core. Constraint-induced movement therapy suits patients with active wrist extension; body-weight-supported and robotic gait training help those who cannot yet walk overground; functional electrical stimulation addresses foot drop and shoulder subluxation. Spasticity is treated when it interferes with function or care - stretch and positioning first, then focal chemodenervation (botulinum toxin, phenol) or intrathecal baclofen for generalized severe tone.
Cognitive rehabilitation is two-tracked: restorative drill-based training for attention, and compensatory strategy training (external memory aids, checklists, environmental modification, routine) for memory and executive deficits - compensation usually yields the more durable gain. Communication ranges from word-finding therapy to AAC devices, voice output, and eye-gaze systems; access methods must match vision, cognition, and motor control. Environmental control units, powered mobility, smart-home technology, and driving evaluation extend independence.
Measure function with tools matched to the question: FIM for burden of care, Barthel for basic ADLs, GOS-E and DRS for global outcome, Berg/TUG/FAC for mobility, and the CRS-R for disorders of consciousness.
Traps: FIM ceiling effects in high-functioning patients; assuming more therapy is always proportionally better; prescribing an AAC device without a trial and training of communication partners.
Rule of thumb: gains track intensity × specificity × practice - but the ceiling is set by arousal and attention, so treat those first.
Worked example: a patient with severe memory impairment wants to return to work. Prioritize compensatory training (phone alerts, one calendar, checklists) with employer accommodation over repeated memory drills, and verify carryover in the actual environment.
