Spinal Cord Injury Terminology Flashcards
Agnosia
inability to interpret information
Agraphesthesia
inability to recognize symbols, letters or numbers traced on skin
Agraphia
inability to write due to lesion in brain, usually seen in combo with aphasia
Aphasia
inability to communicate/comprehend dur to damage to specific areas of brain
Apraxia
inability to perform purposeful learned movements/activites, even though NO sensory/motor impairment to hinder completion of task
Astereognosis
inability to recognize objects via touch
Body Schema
having an understanding of the body as a hole and the relationship of its parts to the whole
Constructional Apraxia
inability to reproduce geometric figures/designs- person often unable to visually analyze how to perform task
Decerebrate Rigidity
characteristic of corticospinal lesion @ level of brainstem, results in extension of trunk and all extremities
Decorticate rigidity
characteristic of corticospinal lesion @ level of diencephalon where trunk/ LE are positioned in ext while UE are positioned in flex
Diplopia
double vision
Dysrthria
slurred/impaired speech due to motor deficit of tongue/other speech muscles
Dysphagia
inability to properly swallo
Emotional Lability
characteristic of right hemisphere infarct- inability to control emotions, presents as outbursts of laughing/crying that are inconsistent with situation
Fluent Aphasia
characteristic of receptive aphasia- speech produces functional output regarding articulation, but lacks content & typically is dysprosodic (affecting the frequency, rhythm, and melody of the voice in such a way that it sounds like the person is speaking with a foreign accent) using neologistic jargon (any speech which is unintelligible)
Hemiparesis
weakness on one side of the body
Hemiplegia
paralysis on one side of the body
Homonymous Hemianopsia
loss of right/left half of field of vision in both eyes
Ideational Apraxia
inability to formulate initial motor plan & impaired sequencing of tasks where proprioception input is necessary for movement
Ideomotor Apraxia
person can plan movement/task, cannot volitionally perform it- automatic movement may still occur, but pt cannot perform additional movement on command
Non-fluent Aphasia
expressive aphasia: speech is non-functional, effortful, contains paraphasias, writing is also impaired
Nystagmus
abnormal eye movement: non-volitional, rhythmic oscillation of eyes- speed is typically faster in one direction, origin is congenital/acquired
Perseveration
state of repeatedly performing same segment of task/ repeating same word/phrase without purpose
Syngery
primitive mass movement patterns coupled with spasticity due to brain damage
Unilateral neglect
inability to interpret stimuli/events on contralateral side of hemispheric lesion: left-sided is most common w/ lesion to right inferior parietal/superior temporal lobes
Vertigo
sensation of movement/rotation of self/surrounding environment- may have peripheral or central origins
