Midterm Dz Info Flashcards
(25 cards)
Changes to muscle bulk
Atrophy, fasciculations: LMN
Hypotonia
LMN
Cerebellum (mild/subtle, not important)
Hypertonia
UMN (spasticity + often rigidity)
Basal ganglia (rigidity)
Decrease in characteristic distribution of strength
LMN, UMN
Hyporeflexia
LMN
Hyperreflexia
UMN
Babinski sign
UMN
Movement disorder
Basal ganglia (hypo or hyperkinetic)
Coordination - appropriate strength
LMN, UMN
Coordination - appropriate for tone and abnormal movements
Basal ganglia
Ataxia lesion location
Cerebellum - includes intention tremor
Chorea - def
rapid, jerk like purposeless NON STEREOTYPED movements
Parkinsonian tremor - def
Present at rest, slow and pill rolling appearance
Essential tremor - def
present with action = fast
Tremor worsens with movement
Improves with alcohol
Dystonia - def
Slow sustained abnormal movement
Akathisia - def
sensation of inner restlessness that is relieved by moving the body.
Tics - def
Involuntary, rapid, jerk like, purposeless, STEREOTYPED movement
Ataxia - def
unsmooth, uncoordinated movements
Parkinsonism - Clinical findings
- Bradykinesia/akinesia
- Rigidity (inc in muscle tone)
- Resting tremor
patient is never weak
Parkinsonism lesion location
- SN (midbrain)
- Putamen
- Globus pallidus
Chorea - lesion location
- Putamen
2. Subthalmic nucleus
LMN lesion signs
Atrophy/Fasciculations Hypotonia Dec strength in characteristic dist Hyporeflexia Appropriate strength in coord
UMN lesion signs
Hypertonia (spasticity + often rigidity) Dec strength in characteristic dist Hyperreflexia BABINSKI SIGN Appropriate strength in coord
Basal Ganglia lesion signs
Hypertonia (rigidity)
Normal strength
Movement disorder: hyper or hypokinetic
Coord is appropriate for tone and abnormal movements
