hypertonicity Flashcards
which tract is the inhibitory tract to alpha motor neurons
corticospinal tract
Damage to what cause rigidity, where they get “cog wheeling” tremors
basal ganglia
spasticity is due to what?
UMN syndrome or corticospinal tract dysfunction
how would you test for spasticity
passive range of motion is ALWAYS PATHOLOGIC
NON-progressive disorder of posture/motor control; and does NOT have cognitive dysfunction
cerebral palsy
what is the most important treatment for cerebral palsy
MOBILITY, physical fitness, and education. keep them moving or they will increase contractures! will make a tremendous difference for later developt
syringomyelia
cyst in spinal cord
What is the main surgical tx for spasticity
Rhizotomy: cutting sensory/dorsal root breaking up reflex arc
how do you indicate if it is a tremor or not
tremors ALWAYS goes away with sleep; otherwise its not a tremor
what are the 3 types of tremors
resting, postural, intension
which tremor is most associated with basal ganglia dysfunction. tremor is most prominent at rest
resting tremor
which tremor is asscoiated with cerbellum dysfunction
intention tremor
which tremor kinetic tremor producing scanning movemnt at the end of motion
intention tremor
Tx for tremors
deep brain stimulation
Gilles Dela TOURETTEs Syndrome
multiple motor tics with AT LEAST ONE vocal/sonic tic
which tremor is most related to parkinsons disease
resting tremor
which tremor can be associated with ataxia
intention tremor
which disorder is snake like involuntary movement between two dystonic posture; constantly moving
Athetosis
chorea is due to what? characteristics?
basal ganglia dysunction; involuntary random parts movemnt DANCING, may finish with voluntary movement
what movement disorder does huntington disease have?
what is the disease due to?
chorea
Caudate nucleus atrophies; cortical tissue atophies
what disorder is caused by lesion in contralateral subthalamic nucleus?
hemi-ballismus
violent form of chorea/limbs fling out in space and typically one sided
Hemi-ballismus
which disorder has abnormal parkinsoninian movemnt DUE to medication/neuropleptics (dopa-blockade)
tardive dyskinesia
which disorder is due to cerebellum damage
ataxia, intention tremor
decompositon of voluntary movement: decrease speed, cordination
affects eyes, speech, limbs, trunk
Ataxia
which disorder is seen with metabolic/toxic encephalopathies of Hepatic/renal origin
Asterixis
which disorder has “negative” myoclonus
Asterixis
involuntary jerks of muscle groups disorder associated with epilepsy, degenerative disorder of cortical tissue OR subcortical/peripheral/ spinal cord causing hemifacial spasm?
Myoclonus
restless legs; when is it worse? what is it due to?
uncomfortable urge to move legs; WORSE at rest. associated with sleep disorder and iron deficiency
movement disorder due to psychiatric probs/making things up in head
psychogenic
basal ganglia dysfunction. tremor in distal limbs (head neck lips tongue). worse with stress/fatigue/ and gets better with rest
postural tremor
abnormal posturing could be generalize/segmental/task specific
tx
dystonia
ie writers dystonia, cervical dystonica,
tx: L DOPA and botox (best tx)
