Neuro Screen Flashcards
Neurological screen versus exam
Neurologic screen- rule in or out need for more comprehensive examination
Exam- in the case of a known neurological diagnosis
Neurologic screen
Differentiate between lower motor neuron pathology (radiculopathy) and upper motor neuron pathology, (spinal cord compression stroke)
Determine source and location of Neurologic dysfunction (sensory motor reflex testing)
Assist in differential diagnosis
Motor element of the Neurologic screen
Observe muscle bulk
Check myotomes
Resistance to passive stretch
Myotome versus dermatome
Myotome is the muscles or muscle groups, innervated by single spine root usually performing similar actions
Dermatome region of skin who sensory information is received by a single spinal nerve root
C5 myotome
Shoulder abduction
C6 myotome
Elbow flexion
C7 myotome
Elbow extension
C8 myotome
Finger flexion or thumb abduction (grip)
T1 myotome
Finger abduction
L2, L3 myotome
Hip flexors
L3, L4 myotome
Knee extensors
L4 myotome
Ankle dorsiflexor’s
L5 myotome
Hallux extension
S1 myotome
Ankle plantar flexors
C5 dermatomes
Lateral anti-cubital fossa proximal to the elbow
C6 dermatome

L3 dermatome
medial femoral condyle of knee
L4 dermatome
