23
Q
perseveration
A
repetitive and continuous behavior, speech or thought that occurs due to changes in cognitive skills
24
Q
dysmetria
A
can’t control distance, speed & ROM necessary to perform smoothly coordinated movements
25
ataxia
lack of coordination of involuntary movements
26
prospopagnosia
face blindness
27
agnosia
can't recognize familiar objects via the senses
28
focus of acute phase of TBI rehab
PHASE 1: in intensive care unit & acute care units of hospitals
- IMPORTANT: wc positioning, inhibit primitive reflexes, increase sitting tolerance, improve respiration/swallowing, interact with environment
- bed positioning
- splinting/casting
- sensory stimulation
- agitation
29
focus of inpatient rehabilitation phase of TBI rehab
PHASE 2: stimulus specific responses (RLA Level V)
- INITIAL: optimize motor function, motor learning, skill acquisition, exercise (GM)
- ataxia
- apraxia
- visual abilities
- visual-perceptual abilities
- cognitive function
- voice & speech
- competence in self management (dysphagia/self-feeding, bed mobility, wc management, functional emulation, community mobility, transfers, home management, community reintegration)
- mediate problem behaviors (environmental/interactive interventions)
- caregiver support
30
focus of postacute rehab phase of TBI rehab
PHASE 3 (last): home based therapy, residential program, day tx program, outpatient community re-entry program)
- cognitive function
- visual & visual perceptual
- self-maintainence
- leisure/social participation
- work
- behavioral/emotional adaptation
- caregiver support
31
TBI splinting
- resting/functional splint: not active/functional
- cone splint: keep fingers from digging into palm
- antispasticity splint: position hand/wrist in functional position, abduct fingers to decrease spasticity
- elbow cast for loss of PROM in elbow flexors
32
how to manage agitation
- common in acute phase
- behavior management strategies
- track arousal/alertness
- yes/no system with eye blinks, head nods, thumbs up
33
bed positioning during acute phase of TBI
abnormal tone: lie on side/semi prone
- sensory input
- pillows, foam wedges, splinting
34
how to treat ataxia
- compensatory strategies for control (weighting body parts, weighted utensil/cup)
35
how to treat apraxia
- hand over hand exercises
- following steps in pics or written on card
36
how to optimize vision
- environmental adaptation
- vision correction
- compensatory strategies: contrasting colors, textured tapes, sunglasses
37
how to optimize visual perceptual abilities
compensatory & rehabilitative
- neglect: encourage use of affected side
- environmental adaptation: moving meal tray to that side
- COMPENSATORY: place all objects in that field of vision for success
38
how to treat expressive aphasia
- conversation exercises with OT recognizing client errors
- ask client to verbalize what they meant to say
- compensatory: communication devices, pictures, charts
39
how should dysphagia be treated?
begin feeding instruction in isolated, quiet area to prevent distraction & grade to include social situations
- rocker knife, plate guard, non spill mug
- place fork down between bites to ensure full chew/swallow
40
how to train in bed mobility
from scooting up/down to rolling, bridging, moving from/to supine, sitting & standing
41
compensatory devices for functional empulation
walker with bags/baskets, canes, reachers
42
community mobility AD
scooters, wheelchairs
43
transfers in PHASE 2 of rehab
difficult due to memory issues
- train caregivers
44
how are clients in PHASE 2 reintegrated back into community?
community trips to practice IADLs in natural environment
45
how to decrease/mediate problem behaviors
isolated, quiet room without roommate
- AT: wander guards (wandering)
- environmental cues to orient to place/time
- calm, concise, deliberate speech
- behavioral management programs
46
how to encourage leisure/social participation in PHASE 3 of TBI rehab
- social skills training groups
- behavior contracts
- role play
- self reflection through video feedback, role modeling
47
how to restore competence in work in PHASE 3 of TBI rehab
- punctuality/feedback response, follow work schedule
- vocational rehabilitation
48
what cognitive issues remain in PHASE 3 of TBI rehab?
memory problems, EF
- provide stable/consistent environment
- self awareness
49
coup
tissue at point of impact
50
contrecoup
opposite pole
51
pharmacologic interventions for TBI
antibiotics, anticonvulsants, sedatives, antidepressants
52
postconcussion syndrome
symptoms continuing for weeks, months, year+ after a concussion
- symptoms usually subside in a few weeks
- symptoms: concussion with/without LOC
- headache, fatigue, cog impairment, dizzy, depressed, impaired balance, irritable, apathy
53
how is postconcussion syndrome dx?
- exercise testing (treadmill)
- neuropsych eval, vestibular testing
54
interventions for postconcussion syndrome
- cognitive/physical rest
- CBT
- antidepressants
