subarachnoid hemorrhage (SAH)
intraventricular hemorrhage
intracerberal hemorrhage
skull fractrues
epidural hematomas (EDH)
subdural hematomas (SDH)
cerebral contusion => intraparanchymal hemorrhage
focal and diffuse axonal injuries with cerebral edema

Q
Secondary Brain Injury and the path to increased ICP
A
Chain of Cellular Events Following Tissue Damage
- glutamate neurotoxicity => increased swelling, ICP
- electrolyte imbalances
- mitocondrial dysfunction
- inflammatory responses
- apoptosis (cell death)
All contribute to brain swelling and increased ICP
Lack of oxygenated blood flow to the brain may also be due to
- systemic hypotension
- anoxia (seen in drowning victims)/hypoxia (seen in pt’s who have an event where they don’t breathe)
- vascualr damage
3

- obtudation (decreased responsiveness)/decreased consciousness
- failure to improve or decreaseing status
- pyschomotor retardation
- memeory loss
- gait deterories (may have wide base)
- intontinence
- unusal symptoms including emotional disorder

Q
What are the 8 levels of cognitive funciton for adults in the Ranchos Los Amigos Scale?
A
- Level I: No response
- Level II: generalized response
- level III: localized response
- Level IV: confused-agitated
- Level V: Confused-inappropriate
- Level VI: Confused-appropriate
- Level VII: Automatic-appropriate
- Level VIII: Purposeful-appropriate
9
Q
Characteristics of each of the Rancho Levels of Cognitive Funciton
A
- Levels 1-3: Low level patients -> Stimulation oriented approach
- stimulation must have structure (include rest periods)
- Levels 4-5: Agitated-Confused and Confused-Inappropriate => Structure Oriented Approach
- won’t be teaching anything new => work on keeping the patient calm and from hurting themselves/others
- if patient get’s worked up, remove the agitating stimulus
- Levels 6-8: Confused, Automatic, and Purposeful-Appropriate => decreased structure, increase task complexity
- level 6 = this is often where people are when starting to look at discharge to home setting with supervision
- as the level increases, you continue decreasing structure while making the tasks more complex

- Appears to be in a deep sleep
- Total assistance
- Glasgow Coma Scale score: 3 out of 15 (3 is the lowest score on this scale and indicates unresposiveness)
12
Q
The following are characteristics of which level of Rancho Los Amigos?

- Open your eyes……Close your eyes
- Stick out your tongue
- Does not remember new information
- Awake intermittently
A
Level III: Localized Response
14
Q
What is the biggest difference between Rancho Levels 2 and 3?
A
- Level 3 = may be able to follow commands
- even if they aren’t following commands, if you pinch them, they are able to draw their arm away instead of having generalized increased arousal (they have a localized response to stimuli)
15
Q
How does a PT Examine a Low Level Patient?
A
- Observation
- Determine level of alterness and response to commands
- assess cranial nerves
- sensory motor exam
- assess neruomuscular system
- try rolling the pt
- can do some neurodevelopmental training
- musculoskeletal system exam
- assess cardiovascular system
- assess integumentary system
- evaluate funcitonal abilities
- try sitting the pt up (can they hold their head up?)
- check for head-riding (if traciton is applied through the upper trap and the head does not come up => this involves the mid-brainstem and is not good)
16

- Test each limb for withdrawal from painful stimulus
- Skin pinch/twist
- Nail bed pressure
- Assess response
- Reflexive (spinal cord level)
- UE: pinch flexor surface of arm, arm flexes, no abduction
- L/E: triple flexion (pinch flexor surface of leg and hip, knee flex + ankle DF)
- Purposeful withdrawal
- pinch flexor surface, arm flexes and abducts: moves away from stimulus
- Reflexive (spinal cord level)

- a response to patient’s internal state of confusion and discomfort
- decreased ability to process information, distractable, fatigure, sleep distrubances
- unable to recall new information
- may recognize family/friends
- can respond to simple commands with structure
- Overreacts: hitting behavior, yelling, foul language, restless
- short attention span, confabulation, no memory
A
Level IV: Confused and Agitated: Maximal Assisstance
- max assit = for structure and for safety and problem solving and sequencing to finish a task
- these patients need structure for safety
- Approach: Structure Oriented Program
21
Q
What are some team goals for treating Ranchos Level IV: confused-agitated?
A
- Decrease intensity, duration and frequency of agitation
- goal is basically to get the pt through this stage as quickly and safely as possible without them injurying themselves or anyone else
- Prevent injury
- Prevent inappropriate response patterning
- Increase attending behaviors to environmental stimuli
- Complete simple tasks with structure (giving the pt verbal cues)
- Facilitate appropriate behaviors
- Family education re patient behavior, team goals
- Facilitate automatic responses in ADL and mobility
22
Q
What are some treatment stratergies to meet goals for Level IV: confused-agitated?
A
- Decrease agitation, prevent injury
- Prevent inappropriate response patterning
- Improve ability to pay attention
- ID and remove sources of agitation
- Structure environment: consistent PT, schedule, treatment session structure, private room
- Reality orientation (where are you? what day is it? who is the president? Why are you here? what happened? => you are in the hospital, you have had an accident, you are here to get better)
- Have help readily available
- Calm with slow rocking, neutral warmth, etc.
- Fatigue hyperactive patients with gait, w/c mobility, ADL’s, etc.
- reassure the pt they are safe
- allow as much movement as is safe
- facilitate automatic, overlearned responses in ADL’s and mobility (i.e., repeated sit-to-stand, walking, washing hands, rolling, sitting up => consider using mobility and things the person has to do every day of their life)
23
Q
what are intervention stratergies that can be used when treating ranchos level IV: confused-agitated?
A
Structure, re-direction
- Skills should be directed to level of function and focus on cognitive endurance rather than progressing to new skills
- Consistency is very important
- Teaching new skills is unrealistic at this level
- Patient is likely to model the behavior of the caregiver
- Therapist must be flexible with treatment activities
- Family education regarding patient behavior and team goals is critical!
- Don’t reinforce inappropriate behaviors
- Consider how you might do the same task but work on the pt’s cognitive endurance (i.e., more repititions)
24
Q
Which rancho level is characterized by the following characteristics?
- Non-agitated
- Agitation and confused are now in response to EXTERNAL stimuli
- Responds to simple commands consistently with assistance
- Performs self-care/ ADL’s with MAXIMAL supervision/ step by step instruction and assist (STRUCTURE)
- Distractible, lacks ability to focus attention (minutes)
- Cannot learn new information
- Memory severely impaired, some immediate memory
- Verbalizations: confabulatory, inappropriate
- Perseverates on basic needs; hunger, thirst, sleep, going home
A
Level V: Confused-Inappropriate
- Approach: Structure Oriented Program
- pt’s can still get agitated if you overstimulate them and irritate and/or challening them too much
- when doing a transfer with this level of pt, they will need maximum supervision and step by step instruction from a cognitive standpoint
25
Which ranchos level has the following characteristics?
* Awake and aware! Now emerges from PTA (post traumatic amnesia), has some day to day recall.
* Goal Directed Behavior
* Moderate assistance/cues to structure tasks, ADL’s
* Purposeful interactions, converses on a simple, social level
* Carry-over with simple tasks
* Can remember main points but will confuse the details
* Can follow a schedule
* Knows month, year, and place
* Can pay attention for about 30 minutes but is easily distracted, difficulty multitasking
* Manage own bathroom needs (with supervison if they are safe enough with their mobility)
* More aware of physical problems than cognitive problems
* Focal injuries more apparent
Level VI: Confused Appropriate
* Approach: Structure Oriented Program
* oftentimes, this is the level that someone can go home from an acute care inpatient rehab into an outpatient program
26
The following are appropraite PT goals for which ranchos level?
* Decrease confusion from environment
* Increase cognitive abilities (i.e., tell the pt a short story and have them try to re-tell it to you)
* Increase frequency, rate, duration & quality of appropriate interactions with environment
* Incorporate increasing cognitive function into functional activity (i.e., when walking, tell a patient their room #, then have them stop and read room #'s on the way back)
Level V: Confused Inappropriate
27
The following are appropriate PT goals for which ranchos level?
* The goal is to maximize functional recovery & prepare the patient for discharge to home & the community
Level VI: Confused Appropriate
28
What are some intervention strategies for Levels V and VI?
* The same strategies as level IV should be considered
* Continue reality orientation
* Repetition
* Memory planner
* Use re-direction if patient gets argumentative

* Balance, coordination, strength, endurance, mobility
* Locomotor training (gait training, wheelchair mobility)
29
What are stratergies applied to the environment for Level V?
* Consistent (as you can't assume the pt being able to get out of bed at the hospital means they can do the same thing at home, you have to perform a home evaluation and structure your environment accordingly to make it consistent)
* Memory aids in visual range (i.e., a sign that says "paper towel" on a paper towel dispenser)
* Minimize distractions (as a treatment, you can vary the amount of distractions from none to increasing them)
* Same therapy staff
* Everyone orients patient to time, place, activity and staff names
* Bring in family pictures & other personal items
* Limit to 2-3 visitors at a time
30

* Head/neck/trunk control
* Balance
* Strengthening
* Simple, repetitive exercises
* Progress to more complex as ability to participate improves
* Early Functional Training
* 1 step activity
* Verbal, visual, tactile cues
* Do not anticipate carry-over of learning to new situations, practice in specific situation
* can perform activities in devlopmental postures (i.e., tall kneeling on a pad while boxing = function + head/neck/trunk control)
Level V: Confused Inappropriate
31
What are some guidelines for treating patients who are confused?
* Structure: repetition of relevant functional activity
* *doing the same thing,...*
* *at the same time, in the same place,...*
* *with the same person, in the same way*
