1

Rancho Los Amigos Levels of Cognitive Functioning

A descriptive scale of response to stimuli that is useful for communicating or documenting general cognitive and/or behavioral status. Rating scale I-VIII.

2

RLA I

No response. Completely unresponsive to any stimuli.

3

RLA II

Generalized response. Pt reacts inconsistently and nonspecifically to stimuli.

4

RLA III

Localized response. Pt reacts to inconsistently but specifically to stimuli

5

RLA IV

Confused/agitated. Pt is in a heightened state of activity. Behavior is bizarre and non purposeful relative to immediate environment. Recall and attention span are poor.

6

RLA V

Confused-inappropriate. Pt able to respond to simple commands but not able to do complex tasks. Memory is impaired. Verbalization is inappropriate.

7

RLA VI

Confused-appropriate. Pt is dependent upon external input but can perform consistently. Memory improved.

8

RLA VII

Automatic-appropriate. Can perform automatically and appropriately in structured environments. Judgement remains impaired.

9

RLA VIII

Purposeful-appropriate. Pt acts appropriately though not perfectly. May have some problems in stressful or unusual circumstances.

10

Glasgow Coma Scale

An objective way to describe a pt's level of consciousness. Consists of eye opening, best motor response, and verbal response.

Score ranges from 3-15.
3-8: severe brain injury
9-12: moderate brain injury
13-15: minor brain injury

11

Alertness

Pt can open eyes, look at examiner, respond fully and appropriately to stimuli

12

Lethargy

Pt appears drowsy, can open eyes, look at examiner, respond to questions but falls asleep easily

13

Obtundation

Pt can open eyes, look at examiner, but responds slowly and is confused. Pt demonstrates decreased alertness and interest in the environment

14

Stupor

Pt can be aroused from sleep only with noxious stimuli, verbal responses are slow or absent, pt returns to unresponsive state when stimuli are removed, demonstrates minimal awareness of self and environment

15

Coma

A state of unconsciousness from which a pt cannot be aroused. Eyes remain closed, no response to external stimuli or environment

16

Vegetative state

A state characterized by the return of sleep/wake cycles, normalization of respiration, HR, BP, and digestion, lack of cognitive response. Can be aroused but is unaware.

17

Persistent vegetative state

A state lasting >1 year for TBI and >3months for anoxic brain injury

18

Minimally conscious state

A state characterized by severely altered consciousness with minimal but definite evidence of self or environmental awareness

19

What could cause an elevated temperature in a pt with brain injury?

Infection
Central origin: damage to the hypothalamus or the brainstem

20

Asymmetrical Tonic Neck (ATNR)

Rotation of the head to one side produces flexion of the skull limbs and extension of the jaw limbs

21

Symmetrical Tonic Neck (STNR)

Flexion of the neck produces flexion of the UE and extension of the LE. Extension of the neck produces extension of the UE and flexion of the LE.

22

Positive Supporting Reflex

Contact to the ball of the foot in the standing position creates rigid extension of the LEs

23

Associated Reactions

Strong voluntary movements in one body segment produces involuntary movement in another resting extremity
