Selective Terms Flashcards
Apraxia
Inability to perform movements, not from loss of strength or coordination
Ideational: cannot perform at all
Ideomotor: cannot perform on command
Astereognosis
Inability to recognize objects by touch alone
Athetosis
Slow, involuntary, wormlike, twisting motions
Cerebral palsy
Cheyne Stokes Respirations
Bizzarre breathing pattern characterized by a period of apnea
Lasting 10–60 seconds, followed by gradually increasing, then decreasing depth and frequency of respirations
Can occur with severe traumatic brain injury or coronary heart failure
Chorea
Rapid, involuntary, jerky movements
Huntington’s
Clonus
Rhythmic oscillation of a muscle in response to sustain stretch in patients with upper motor neuron disease
Decerebrate rigidity
Contraction of upper extremity and lower extremity extensor muscles
From brainstem injury
Decorticate rigidity
Contraction of upper extremity flexors with lower extremity extensors
Dysmetria
Inability to judge distances – seen in cerebellar dysfunction
Horner’s Syndrome
Ptosis of eyelid, constriction of pupil, lack of sweating at ipsilateral face
From stroke or anterior – inferior, for posterior-inferior cerebellar artery
Morton’s neuroma
Excessive pronation during stance leads to compression of third and fourth metatarsal’s
Nerve can enlarge, forming neuroma
Somatognosia
Lack of body awareness/relationships
Apraxia vs ataxia
Apraxia – inability to perform voluntary movement from brain damage
Ataxia – lack of coordination
Agnosia
Inability to recognize familiar objects with one form of sensation, example visual agnosia
Lead pipe rigidity
Uniform throughout
Basal ganglia lesions
