Exam 2 Flashcards
Coma
- complete paralysis of cerebral function; a state of unresponsiveness
- eyes are closed; no response to painful stimuli;
- reflexes may be present depending on the site of the lesion
- 2-4 weeks, nearly all patients begin to awaken
Consciousness
- alert wakefulness
- clearly appreciates environment
- responds quickly and appropriately to visual, auditory, other sensory stimuli
- gradual recovery of orientation and recent memory
Minimally Conscious State
definite evidence of environmental awareness
characterized by inconsistent behavior but reproducible and localized rather than generalized
PT for patients in a minimally conscious state includes:
- disorders of consciousness program
- structured stimulation and recording of responses to document emergence
Persistent Vegetative State
- wakeful, reduced responsiveness
- no evident cerebral function
- eye tracking, minimal motor
- no speaking or response to verbal stimuli
- non-purposeful movement
JFK Coma Recovery Scale
a research tool used for studying recovery of patient’s in a coma; 23 items that comprise six subscales addressing:
- auditory
- visual
- motor
- oral motor
- communication
- arousal functions
What are the two most commonly used clinical rating scales for patients s/p TBI?
- Rancho Los Amigos Hospital Level of Cognitive Functioning Scale (LOCF)
- Glasgow Coma Scale
Rancho Los Amigos LOCF
- consists of 10 levels
- describes pt. during recovery
- not always clearly in one level
Rancho Los Amigos LOCF: Levels 1-3
total assistance
Rancho Los Amigos LOCF: Levels 4-5
maximal assistance
Rancho Los Amigos LOCF: Levels 6
moderate assistance
Rancho Los Amigos LOCF: Levels 7-10
progressively less assistance
Glasgow Coma Scale
- quantify degree of coma at time of injury, and every 2-3 days
- three categories (EMV score): Eye opening, best Motor response, and Verbal response
- 3-15 point range; 3 = coma
Functional Assessment Measure
an adjunct to the FIM to specifically address major functional area less emphasized in the FIM including:
- cognitive
- behavioral
- communication
- community functioning
Mortality after TBI
over 1600 subjects surviving 1 year after injury, with increased risk of death from:
- aspiration pneumonia
- seizures
- pneumonia
- suicide
- digestive conditions
Postural changes following TBI:
- decorticate posture - UE flexed, LE extended
- decerebrate posture - UE and LE extended
both indicate low brain function and absence of selective movement
Sensory changes following TBI:
- light touch
- deep pressure
- pain
- temperature
- proprioception
- kinesthesia
- cranial nerve involvement
Motor changes following TBI:
- monoparesis
- hemiparesis
- tetraparesis
- coordination, timing, sequencing deficits
*Highly variable between patients
Perceptual changes following TBI:
- unilateral visuospatial neglect
- hemispatial neglect, hemiagnosia, and contralateral neglect
Input vs. Output Neglect
input neglect or “inattention” includes ignoring contralesional sights, sounds, smells, or tactile stimuli; output neglect includes motor and pre-motor deficits. A person with motor neglect does not use a contralesional limb despite the neuromuscular ability to do so.
The presence of neglect w/in the first ten days following TBI is a strong predictor of ____ __________ ________ after 1 year than several other variables
poor functional recovery
Perception
integration of sensory info into meaningful psychological info, including prior information; more complex than sensation
Cognitive impairments following TBI:
- memory deficits
- attention deficits
Memory deficits
post-traumatic amnesia - time between the injury and the time patient remembers ongoing events (short-term); declarative (habit) vs. declarative (facts)
Retrograde vs. Anterograde amnesia
retrograde amnesia is the inability to recall memories of prior events, while anterograde amnesia is the inability to make new memories
Attention deficits
- decreased attention span
- impulsiveness/lack of safety awareness
- distractibility
Emotional/behavioral changes
most enduring and socially disabling of any sequelae
- disinhibition
- lability
- aggression
- low frustration tolerance
- inpatient
Secondary body function/structure impairments
- soft tissue contractures
- altered muscle tone/spasticity
- pressure sores
- DVT
- heterotopic ossification
Factors in predicting outcomes following TBI
- severity of injury
- duration of coma
- duration of post-traumatic amnesia (≥12 wks = poor; ≤4 wks = good prognosis)
- low Glasgow Coma Scale
Predicting outcomes
motor disturbances generally have GOOD prognosis, but cranial nerve injury - hearing, smell, vestibular sense are rarely fully recovered
Care Manager/Case Manager
coordination of care, seeking appropriate services, conducting team meetings, family liaison, etc.
Physical Therapist
mobility skills, transfers, walking, balance, attention, memory, community reintegration
Occupational Therapist
self-care, gross and fine motor skills, emphasis on UE, memory, attention, organization, community reintegration
Speech Language Pathologist
communication: rehabilitation of dysarthria, aphasia, swallowing (dysphagia), along with memory, attention, community reintegration
Physician
medical management; medication, imaging, testing
Nurse
personal care and carrying out medical plan, follow-up care consistent with rehab team
Neuropsychologist
assessment of cognition and behavior through testing; psychological, personal, interpersonal, and wider contextual circumstances
Precautions during examination of pts. following a TBI
- cervical ROM caution: shunts, head should be elevated in acute phase
- passive ROM: LOCF I-III
- position changes: confirm status of fracture before standing, sitting contraindicated if unstable ICP or BP, tube/line management
Essential outcome measures during examination of pts. following a TBI
- FIM
- Modified Ashworth Scale
- Balance assessments
- Timed walking tests (2 min, 3 min)
- Functional reach balance test
- Single-limb stance
- activity limitations
- bed mobility
In which two ways should you classify patients following a TBI?
- Sahrmann & Scheets model
2. Rancho Los Amigos LOCF

Behavioral Treatment Strategies
- assumption: cognitive recovery can be inferred from progressive behavioral changes
- LOCF is determined by observation throughout the day

What are the specific recommendations to make regarding ramps?
1” rise per 1 foot of length; pay attention to neighborhood zoning problems
Multiple Sclerosis
MS causes the body’s immune system to mistakenly attack and destroy the myelin that surrounds the axons of nerves in the CNS (brain, spinal column, and/or optic n.)
Gliosis
the damaged myelin forms scar tissue (sclerosis). This scarring along the myelin sheath interferes with the transmission of nerve impulses, which produces the symptoms of MS.
T/F: Multiple Sclerosis is considered an auto-immune disease
true; it is also considered an immune-mediated disease
Epidemiology of MS
- most common neurological disorder in young people, typically diagnosed between ages 20-50
- more common in women, but more progressive in men
- more frequent in caucasians, especially those of northern European ancestry
