Sensory Changes Brain Injury Sequelae
Proprioception - inability to feel where a body part is in relation to rest of body or things around them
Vision– hemianopsia and hemi-sensory imercaeption
Apraxia (ideational and ideomotor)
Dysphasia
Bowel and bladder changes
What is hemianopsia?
blindness in half of visual field of each eye
what is hemisensory imperception?
visual input from one side of body is not consistently recognized or attended to
What is the difference between ideational and ideomotor apraxia?
Ideational: inability to plan movements related to interaction with objects, due to lost perception of the objects purpose
Ideomotor: inability to translate an idea into motion; no loss of ability to perform an action automatically, but the action cannot be performed upon request
What are the 4 basic assessment Scales
Glascow Coma Scale
Ranchos Los Amigos Scale
Orientation Log
Agitated Behavior Scale
The glascow coma scale is most often performed in…
what does a higher score mean?
acute care
higher score = higher performance, better prognosis
Which level of Ranchos Los Amigos?
Continuous absence of observable change of eye opening
Rancho I: Coma
Which level of Ranchos Los Amigos?
State of wakefulness without awareness of self or environment
patient has sleep-wake cycles and a range of reflexive and spontaneous behaviors
Rancho II: Unresponsive Wakefulness Syndrome, Vegetative
Which level of Ranchos Los Amigos?
Purposeful responses, (squeezing hand on command), correctly demonstrative use of object
Command following may be inconsistent
Rancho III: Minimally conscious, localized response
Which level of Ranchos Los Amigos?
Confused, disoriented, restless, agitated
unaware of current situation
limited ability to correct inappropriate actions or behaviors
*Unable to lay down new memories or learn from mistakes / no new learning
Rancho IV: Confused-Agitated
Which level of Ranchos Los Amigos?
Generally non agitated, but may have episodes of agitation if overstimulated (fatigue, environment)
Confused and inappropriate
short attention span (+- 5 mins)
Confabulation, perseveration, wandering
no new learning
Rancho V: Confused-Inappropriate
Which level of Ranchos Los Amigos?
Can start to learn basic skills again, but impaired memory
Difficulty with changes to routine
Attending to tasks up to 30 mins
Benefits from goal-oriented behavior, needs cueing to complete tasks
Some awareness of self and others
