Q

What is the definition of a TBI?

A

damage to the brain, which occurs after birth and it not related to a congenital or degenerative disease. Impairments may be temporary or permanent and cause partial or functional disability or psychosocial maladjustment.

25
what is retrograde amnesia?
memory loss prior to the accident | may gradually, but incompletely improve
26
what is anterograde amnesia
inability to learn new long-term declarative info | typically last to improve
27
what are characteristics of Glasgow Coma Scale 1?
Pain: has no motor response to pinch, does not open eyes Speech: makes no noise
28
what are characteristics of Glasgow Coma Scale 2?
Pain: opens yes when pinched body become rigid in an extended position when examiner pinches victim(decerebrate posturing) Speech:makes sound that examiner can't understand
29
what are characteristics of Glasgow Coma Scale 3?
Speech: opens eyes when asked to in a loud voice talks to examiner, can understand but makes no sense Pain: flexes body away when pinched by examiner
30
what are characteristics of Glasgow Coma Scale 4?
Spontaneous: opens eyes on own Pain: pulls a part of body away when pinched by examiner Speech: Seems confused or disoriented
31
what are characteristics of Glasgow Coma Scale 5?
Pain: pulls examiner;s hand away when pinched Speech: carries on a conversation correctly and tells examiner where and who he or she is and the month and year
32
what are characteristics of Glasgow Coma Scale 6?
command: follows simple commands
33
What are characteristics of a Rancho Level 1?
no response total assistance no response to pain, touch, sight or sound
34
What are characteristics of a Rancho Level 2?
generalized response total assistance generalized reflex response to stimuli
35
What are characteristics of a Rancho Level 3?
localized response total assistance demonstrates withdrawal or vocalization to painful stimuli responds inconsistently to commands
36
What are characteristics of a Rancho Level 4?
confused agitated max assist agitated, alert, very active, aggressive or bizarre behaviors, performs motor activities, but behavior is non purposeful, extremely short attention span
37
What are characteristics of a Rancho Level 5?
confused, inappropriate, non-agitated max assist gross attention to environment, highly distractibly, requires continual redirection, difficulty learning new tasks, agitated by too much stimulation. may engage in social conversation, but with inappropriate verbalization
38
What are characteristics of a Rancho Level 6?
confused, appropriate mod assist inconsistent orientation to time and place. selective task attention, recent memory impaired, begins to recall past, consistently follows simple directions, goal-directed behavior with assistance
39
What are characteristics of a Rancho Level 7?
automatic appropriate min assist performs daily routine in highly familiar environment in nonconfused, but automatic robot-like manner, skills noticeably deteriorate in familiar and unfamiliar environment. lacks realistic planning for own future.
40
What are characteristics of a Rancho Level 8?
purposeful and appropriate stand by assist consistently oriented to person place and time. initiates and carries out steps to complete familiar personal, household, community, work and leisure routines with stand-by assistance and can modify the plan when needed with min assist.
41
What are characteristics of a Rancho Level 9?
purposeful appropriate stand by assist on request able to think of consequence of decision or actions with assistance when requested. Initiates and carries out steps to complete familiar personal, household, community, work and leisure routines independently and unfamiliar personal household, work, and leisure tasks with assistance when requested
42
What are characteristics of a Rancho Level 10?
purposeful appropriate modified independence able to think about consequences of decision or actions with assistance when requested
43
what is the modified ashworth scale used for?
used to manually rate spasticity
44
what is a 0 on the Modified Ashworth Scale?
no increase in tone
45
what is a 1 on the Modified Ashworth Scale?
slight increase in muscle tone, manifested by a catch and release or min resistance at the end of the ROM when the affected part(s) is/are moved in flexion or extension
46
what is a 1+ on the Modified Ashworth Scale?
slight increase in muscle tone, manifested by a catch, followed by minimal resistance throughout the remainder(less than half) of ROM
47
what is a 2 on the Modified Ashworth Scale?
more marked increase in muscle tone through most of the ROM, but affected part(s) easily moved

memory, difficulty adapting. difficulty with motor learning, depression, PTSD, substance abuse, aggressive behavior
51
What is the clinical picture of TBI?
``` decorticate, decerebrate, and motor rigidity abnormal muscle tone and spasticity primitive reflexes muscle weakness decrease functional endurance ataxia postural defects/deficits dysphagia cognitive deficits limitation in joint motion visual and perceptual deficits behavioral and pyschosocial challenges ```
52
what is ataxia?
movement abnormality characterized by incoordination, impaired sitting and standing balance, or both
53
what are the postural defects seen in TBI?
Pelvis=posterior pelvic tilt Trunk=kyphosis, scoliosis, and lordosis, and lateral trunk flexion Head and Neck=forward flexion or hyperextension of the neck and lateral flexion of the head(follows trunk)
54
what are the postural deficits seen in TBI?
scapula=depressed, protracted or retracted, downwardly rotated, or all due to imbalance in scapular muscle tone UE's= bilaterally or unilaterally involved LE's=severe extension patterns in both LE's also hip ADD, internal rotation, knee flexion, plantar flexion, and inversion of the feet.
55
what can cause the limitation in joint motion for TBI pts
``` increase muscle tone volitional resistance contractures heterotopic ossication fractures or dislocations pain ```
56
What are some of the areas of cognitive deficits seen in pts with TBI
``` attention and concentration memory initiation and termination of activities safety and awareness and judgement processing info executive functions and abstract thought generalization ```
57
what are some of the pyschosocial challenges for pt's with TBI?
``` self-concept social roles independent living status dealing with loss affect changes ```
58
what are the driving rehabilitation and the unique contributions by OT?
``` understands medical conditions and disease process analyze ADLs and IADLS knowledge of adaptive devices occupation-based interventions social impact roles ```
59
What does the OT driving Assessment cover?
sensory, cognitive, and motor performance performance patterns safety concerns contextual and environmental barriers and supports influence of community mobility and driving on the client's ability to participate in daily life address mental health issues when community mobility/driving is comprised
60
Loss of consciousness or amnesia for less than 10 min is characteristic of what type of TBI? What would be the Glasglow coma scale
``` Mild TBI Glasgow Coma Scale 13-15 no skull fracture on physical examination nonfocal neurological examination 80% of TBIS ```
