Cognition and Perceptual Impairments categories

~higher order/ executive function


Cognition and perceptual impairments: cognition categories

~attention deficits

~Selective attention
~Divided attention
~Alternative attention


Cognition and perceptual impairments: cognition categories- memory impairments

~immediate recall
~short- term

Ability to move



Want to do something so you plan your movement


Purposive action

When you are able to do an action that has a pursue


Cognition and perceptual impairments: Higher-order/ executive function

~Purposive action
~Effective performance


Cognition and perceptual impairments: performance

~body scheme/ body image
~spatial relations impairment


Cognition and perceptual impairments: body scheme/ body image

~Unilateral neglect
~Right-left discrimination
~Finger agnosia


Cognition and perceptual impairments: spatial relations impairment

~Figure-ground discrimination
~Form discrimination
~Spatial relations
~Position in space
~Topographical disorientation
~Depth and distance perception
~Vertical disorientation


Unilateral neglect

~inability to recognize half of your sensory form ½ your body that is not due to a sensory loss
~Usually left side
~pusher- push towards their affected side/ involved side
~The person will not know/ think about the involved side; the body wants to compensate and will push towards the involved side to try and make a new midline



~No insight or awareness of their injury; their brain does not know that they has had the injury
~Usually resolved in the first few months
~Usually more prominent right CVA



~“body agnosia”
~Difficulty with body structure and the relationship with one body part to another; where is my elbow in relationship to my hand


Right-left discrimination

~No clue on R/L
~Have to put some other input besides r/l; tapping, colors, etc


Finger agnosia

~Cant figure out how to use the fingers in a helpful fashion; any fine motor skill is not easy
~Opposition, tying shoes, buttoning, etc


Figure-ground discrimination

~You wont be able to discriminate between lines to find a figure; will just random line and not image
~Cant see where things are because they are all just in the background
~Cant figure out where to grab on a wheelchair


Form discrimination

~Small difference are hard for the pt to discriminate/ separate
~If you open up a drawer- there are lots of long skinny object (pencils, pens, tooth brush, etc) but they all look the same to the stroke pt


Position in space

~Up, down, in, out, below, above- all a jumbled mess to them
~Get on top of the table? Put you hand on top of your knee? Etc
~They cannot understand what that means


Topographical disorientation

~Map- if you want them to gym from their room, they wont remember how they got there (the twists and turns)
~They wont remember how to get to the restroom
~Very common in TBI and stroke; good reason to keep them in therapy


Depth and distance perception

~Can be visual
~Do you where glasses? Near or far sighted?
~Stairs- can look like a slide or a wall; pouring into a glass; curves; potholes/ bumps in the ground


Vertical disorientation

~Everyone is off by 10-15*at first after stroke; not standing straight because they think the world is off tilted
~The world is off to them, so they walk funny/ at an angle
~*like you are walking through the crazy house
~Typically gets better; can occur in either type of stroke (right or left)



~visual agnosia
~auditory agnosia
~tactile/ asterognosis


Visual agnosia

~Has normal eye function/ their eyes work
~They have problems naming the object when they just looking at it
~If they can hold it, they can name it right away
~Just can’t process the visual pathways to say what it is


Auditory agnosia

~They can still hear, but is a sound has a similar sound, it sound the same
~Inability to recognize/ decipher the sounds
~Bark and lightening; cell phone and an ambulance going down the street, voices will probably sounds similar
~Typically have other processing issues


Tactile/ astereognosis

Cant tell you what it is when it is in your hand without looking at it





Ideomotor apraxia

~Breakdown btw concept and performance
~They can do the task but they cannot do the task when asked
~Can brush their teeth without thinking, but if you ask them to do it, they cant
~Can get it form an idea to a motor
~You can sometimes trick them into doing it (if you tell them to stand, they cant, but if you try and get them to get a drink of water, they will easily stand up)
~Also tend to perseverate (motor or verbal)- yes, yes, yes, yes or they keep doing the same action over and over again


Ideational apraxia

~A complete failure of the conceptionalization of the task
~Cant even do the task
~Have no idea on how to put the tasks together to walk, stand up, roll over, etc


Constructional apraxia

The ability to put parts together to make a whole (in the correct way)


Dressing apraxia

~Are you able to dress properly
~Putting underwear on the outside, etc


Non equilibrium tests

Does someone have coordination outside of balance; don’t have to know all these, but should know at least one for UE and LE for exams


Non equilibrium tests- list

1) Finger-to-nose
2) Finger-to therapist’s finger
3) Finger-to-finger
4) Alternate nose-to-finger
5) Finger opposition
6) Mass grasp
7) Pronation/supination
8) Rebound test
9) Tapping (hand)
10) Tapping (foot)
11) Pointing and past pointing
12) Alternate heel-to-knee; heel-to-toe
13) Toe to examiner’s finger
14) Heel on shin (common)
15) Drawing a circle
16) Fixation or position holding


Equilibrium test

Testing balance- berg’s, etc


COM- stands for

Center of mass


COM- male vs female

Men COM is around the navel, but females are lower because of hips


Cone of stability

~if you take your COM to the limits of the BOSs without falling (leading forwards/ backwards/ side to side)
~After you fall, the person has a very small cone



~after the fall, fight standing up
~will push back so they will move backwards
~rigid extension


BOS- stand for

Base of support



~Feet: different when they are shoulder width, staggered, narrow, etc
~can be your butt when sitting- want 90/90/90 (hip, knee, ankles); moving forward and backwards will change BOS bc it changes where the feet are


As you get older, your BOS will..

they get more narrow



Maintaining your COM over your BOS


Influence COM

~Large boobs
~Larger belly/ pregnancy
~Injuries on LE- will stand on the uninvolved side


If you start to fall to try and keep from fall, what are the 3 steps

~Bend at the ankle
~Bend at the hip
~Take a step


If pt has fallen...

~You want to work on putting them right to the point of them falling without making them fall
~Don’t let them fall!
~Strengthen muscles and neuro system to work faster
~Will find out where they are weak and work on that part
~You want to perturb them, unstable surfaces, etc
~Want to do a lot of single leg stuff (walking involves single leg stance)


Standing with assistive devices- cane

Com is in the center, but if you have a cane, the cane will move the COM towards the cane side


Standing with assistive devices- crutches

Crutches are like a double cane (one on each side) people need to be really good with their BOS with the feet are off the ground


Standing with assistive devices-walker

~Walkers- make sure that the pt is within the walk’s base
~if the walker is in front of the pt, the COM is way in front of the feet
~Different walkers: Standard walker, rolling walker, posterior walker, hemiplegic walker


Standing with assistive devices- roller

Roller- will not let you get within the walking space


Standing with assistive devices- cane

COM is normally in the center, but if you have a cane, the cane will move the COM towards the cane side
