Rehabilitation in Cerebrovascular Disease and Traumatic Brain Injury Prawit Rungcharoensak M.D. Dept. of Rehabilitation Medicine BMA Medical College & Vajira Hospital
Cerebrovascular disease / stroke Prevalence : 690 / 100,000 Risk factors 1. Age (<45 yr : 60/100,000 ; 45-65 yr : 998 ; >65 yr : 5063) 2. Hypertension 3. Valvular heart disease, arrhythmia (AF) 4. D.M. 5. Previous stroke / TIA 6. Race 7. Sex 8. Smoking 9. Family Hx. 10. DM 11. Elevated fibrinogen 12. Erythrocytosis 13. LDL
Pathology : 1. Ischemic stroke (80-90% of CVD) Thrombotic (40%) : previous stroke, large vv. Embolic : small vv., younger age, heart disease Lacunar : penetrating artery in basal ganglion, internal capsule, brainstem (good recovery) 2. Hemorrhagic stroke mortality 50-70% Lesion : putamen, thalamus
Pattern of neurological recovery Hypotonia / flaccidity (48 hr) Flexion / extension synergies (2-30 d.) Isolated movement (6-33 d.) Full recovery (10% of Pt.) Prognosis : ~12 weeks
Rehabilitation Goal : Independence Candidate : able to perceive, understand, follow command (verbal/gesture) Assessment : • pathology • site of lesion • symptoms & signs • risk factors • stage of neurological recovery • functional performance
Positive predictors 1. Bladder control (within 1-2 wk) 2. Recovery of trunk, hip, shoulder muscles within 2-4 wk (proximal muscle) 3. Recovery of each muscles 4-6 wk (Isolatemuscles) 4. Family support 5. No depression 6. Good perception
Negative predictors 1. Prolonged coma 2. Prolonged flaccid (> 2 months) 3. Severe proximal muscles spasticity 4. Inability to control bladder & bowel (within 2-3 wk) 5. Severe unilateral neglect 6. Severe intellectual / memory impairment 7. Visuospatial deficit / hearing deficit 8. Previous stroke 9. Severe depression 10. Associated diseases (CAD, CHF, PVD)
Deficits 1. Cognitive problems • Left hemiplegia : perceptual deficit, neglect, poor insight & judgement • Right hemiplegia : aphasia 2. Behavioral / emotional problems • Depression (25-60%) : 6 m- 2 yr, 70% of right hemiplegia • Undue cheerfulness (anxiety, lability) : right frontal lobe • Apathy : right frontal lobe • Denial
Deficits 3. Communication disorder • Language : aphasia (spontaneous recovery 3-6 m) • Articulation : apraxia, dysarthria, dysphonia 4. Sensory deficits • Visual field deficit • Visual perceptual deficit (right hemisphere) : body image, special related disorder • Peripheral sensory deficit (propioception)
Deficits 5. Motor deficits • Spasticity • Incoordination • Weakness • Motor apraxia 6. Bladder, bowel, sexual deficits • Bladder : 70% of Pt. can control (PC exercise, CIC) • Bowel : diet (75% of Pt. can control, incontinence in bed ridden) • Sexual : in 70% of cases
Rehabilitation program 1. Mobility • Bed positioning • Therapeutic exercise (ROM) • Bed mobility • Sitting balance / trunk control training • Transfer training • Wheelchair management • Standing / progressive ambulation (ROM, propioception, sitting balance, cognition, hip extensor power) 2. Activities of daily living • UE function, good sitting balance, no sensory deficits
Complications 1. Shoulder subluxation (50-80%) Causes : - paralysis of shoulder M., flaccid stage - laxity of joint capsule Treatment : shoulder support / sling, ES, proper bed & sitting position 2. Shoulder hand syndrome (RSD) (12.5%, Mo 2-4) Causes : ANS disorder, increased sympathetic tone Stage 1: pain on ROM, swelling of wrist & fingers, cold skin Stage 2: swelling, joint stiffness, osteoporosis Stage 3: skin dystrophy, osteoporosis Treatment : ROM, wrist & hand splint, pain reduction (TENS, drug)
Complications 3. Seizure (10-15%) Early seizure (2 wk) : brain swelling, cytotoxic metabolite, embolic > thrombotic stroke, no treatment Late seizure (6 m - 2 yr) : hemorrhagic stroke, medication 4. Aspiration Pneumonia (50%) Causes: - swallowing disorder, dysphagia (brainstem lesion) - cognitive function Treatment : oral hygiene, proper eating position, proper diet, swallowing training
Traumatic Brain Injury (TBI) • Traffic accident 60% Risk factors 1. Age : 15-24 yr, 0-5 yr, >65 yr 2. Sex : male > female 3. Alcohol 4. Other : psychological, personality
Classification of TBI 1. Severity : Glasgow Coma Scale (GCS) Severe : 3-8 Moderate : 9-12 Mild : > 13
Classification of TBI 2. Pathology 2.1 Focal : • Focal cortical contusion (FCC) • Deep hemorrhage • Focal hypoxic-ischemic injury (FHII) 2.2 Diffuse : • Diffuse axonal injury (DAI) • Diffuse hypoxic-ischemic injury (DHII) 2.3 Indirect pathological condition & secondary phenomena : • extracerebral hematoma, herniation syndrome, hydrocephalus, chronic subdural hematoma, hygroma, posttraumatic seizure
FCC frontal polar, orbital frontal : apathy, disinhibition, IQ anterior inferior temporal : aphasia, agnosia Deep hemorrhage basal ganglion : hemiparesis, discordination, hypertonia, movement disorder, aphasia / neglect FHII posterior cerebral artery : hemianopia, amnesia DAI corpus collosum : coma (without lucid interval), confusional state, residual attention, cognitive & behavioral impairments
Recovery of diffuse TBI DAI : • Coma • Vegetative state • Mute / low level responsiveness • Confusional state : attention deficit, abn. behavior • Evolving independence • Intellectual / social competence FHII : prolonged coma & confusion, poor prognosis
Specific impairments after TBI Physical : 1. Movement control* 2. Abnormal tone, spasticity 3. Cerebellar incoordination 4. Involuntary movement 5. Seizure Neuropsychological : 1. Neurological : arousal, attention (memory), behavior 2. Postconcussion syndrome : headache, dizziness, insomnia, depression, fatigue 3. Psychological : depression, anxiety, posttraumatic stress
Rehabilitation program Acute : neurosurgery Acute rehabilitation phase : Coma : • prevention of complications • coma stimulation (sensory stimulation, sitting) Confused : • rehab team approaching • medication • behavioral management
Rehabilitation program Postacute rehabilitation phase : (post discharge) • Day care • Day treatment • Transitional living center Cognitive rehabilitation : • Functional skill training (ADL) • Process oriented rehabilitation (attention, executive function)
Outcome 1. Severe TBI (GCS 3-7) : dead 35-50%, cognitive impair = 21%, abn behavior = 24% 2. Mild TBI (GCS 12-15) : postconcussion syndrome 3. Focal pathology : multiple, mass effect, abn pupil = poor prognosis 4. Diffuse pathology : GCS, length of coma & posttraumatic amnesia (PTA) 5. Recovery rate
