Neuro Exam/Localization Flashcards
1
Q
LMN Signs
A
- Areflexia/Hyporeflexia
- Severe, rapid muscle atrophy
- Hypotonia/atonia of innervated mm
* *decreased to absent reflexes
2
Q
C1-C5 Lesions
A
Clinical Picture:
- Tetraparesis
- Sensory ataxia
- Postural reaction deficits to all four limbs
- UMN signs to all four limbs
3
Q
C6-T2 Lesions
A
Clinical Picture:
- Tetraparesis/tetraplegia
- Sensory ataxia
- Postural reaction deficits to all four limbs
- LMN signs to thoracic limbs
- UMN signs to pelvic limbs
4
Q
T3-L3 Lesions
A
Clinical Picture:
- Paraparesis/paraplegia
- Sensory ataxia of trunk and/or pelvic limbs
- Postural reaction deficits to pelvic limbs
- UMN signs to pelvic limbs

7
Q
Polyneuropathies
A
Clinical Picture:
- generalized weakness; tetraparesis
- sensory ataxia may be present
- true LMN signs to all four limbs
- may affect sensory, motor, or both systems
8
Q
Polymyopathies
A
Clinical Picture:
- Generalized weakness; tetraparesis
- neuro exam typically normal
- mm atrophy +/-
- CK level may be elevated
9
Q
Junctionopathies
A
Clinical Picture:
- generalized weakness
- postural reactions typically normal
- reflexes typically normal initially; may decrement/fatigue with repeated testing
- typically no mm atrophy
