Q

Cerebellar of Basal Ganglia Disorder?

Choreoathetosis

A

basal ganglia disorder

both chorea & athetosis: slow, involuntary, writhing, twisting, “worm-like” movements (UE>LE & neck, face, tongue, trunk) combined with involuntary, rapid, irregular and jerky movt’s

Q

Cerebellar of Basal Ganglia Disorder?

rebound phenomenon

Q

Cerebellar of Basal Ganglia Disorder?

Intention tremor

A

cerebellar disorder

Occurs during movement; stops with rest

17
Q

Cerebellar of Basal Ganglia Disorder?

rigidity

A

basal ganglia disorder

increase in muscle tone causing greater resistance to passive move

18
Q

Cerebellar of Basal Ganglia Disorder?

speech slow, slurred, hesitant, inappropriate pauses, on-word-at-a-time quality

19
Q

Cerebellar of Basal Ganglia Disorder?

Athetosis

A

basal ganglia disorder

slow, involuntary, writhing, twisting, “worm-like” movements (UE>LE & neck, face, tongue, trunk)

Q

Cerebellar of Basal Ganglia Disorder?

hemiballismus

A

basal ganglia

Large amplitude involuntary movement. Causes large amplitude “flinging” motions of the extremities
