1

Upper Motor Signs

Positive Babinski
Hyperflexia
Hypertonia

2

Lower Motor Signs

Negative Babinski
Hypoflexia
Hypotonia
Fasciculation (random twitching)
Atrophy

3

Peripheral Neurological Syndromes

Neuropathy- dysfunction of nerves
Polyneuropathy- diffuse dysfunction of peripheral nerves
Mononeuropathy- dysfunction of single nerve
Radiculopathies- spinal nerve root dysfunction

4

Myopathy Syndrome

Diffuse skeletal muscle weakness
SYMMETRIC BILATERAL PROXIMAL LIMB WEAKNESS

5

Median Neuropathy (C5-T1)

THUMB ABDUCTION, thumb flexion, thumb
opposition
Sensation of all anterior & distal posterior
skin of thumbs, index fingers, middle fingers,
and lateral halves of ring fingers

6

Ulnar Neuropathy (C8-T1)

Adduction and abduction of all fingers
except thumb abduction; little finger
opposition; flexion of ring and little fingers
Sensation of anterior & posterior medial
hands including the little fingers and medial
halves of the ring fingers

7

Radial Neuropathy (C5-T1)

Finger and wrist extension
Sensation of the lateral posterior hands and
the proximal posterior skin of the thumbs,
index fingers, middle fingers, and the lateral
halves of the ring fingers; brachioradialis
reflexes

8

Seventh Cervical Radiculopathy

Elbow extension, wrist and finger extension
Sensation of the posterior forearms, hands,
and middle fingers; triceps reflexes

9

Sixth Cervical Radiculopathy

Shoulder abduction, elbow flexion
Sensation of the lateral forearms, lateral
hands, thumbs, and index fingers; biceps &
brachioradialis reflexes

10

Peroneal Neuropathy

Foot dorsiflexion, toe extension, foot
eversion
Sensation of the lateral lower legs and the
medial and superior feet

11

Lateral Femoral Cutaneous Neuropathy

Abnormal sensation of the lateral thighs

12

Fifth Lumbar Radiculopathy

Hip abduction, knee flexion, foot
dorsiflexion, toe extension, foot inversion &
eversion
Sensation of the lateral upper & lower legs
and medial & superior feet; difficult to elicit
stretch reflexes of the medial hamstrings

13

First Sacral Radiculopathy

Hip extension, knee flexion, foot
plantarflexion, toe flexion
Sensation of the posterior upper & lower
legs AND lateral & inferior feet; Achilles
reflexes

14

Polyneuropathy

Symmetric distal limb weakness; lower
motor signs
Sensory loss of distal limbs

15

Neuromuscular Junctionopathy

Same symptoms as myopathy, drooping eyelid (ptosis) ophthalmoparesis.
Possible Dysarthria, dysphagia, dysphonia

16

Myelopathy

Syndrome of Spinal cord tracks

17

Lower Sacral Myelopathy and cauda equina syndrome

Dysfunction of cauda equina and lower sacral spinal cord.
Dysfunction to perineum, bladder, bowel and genitals
Legs not involved

18

Lumbosacral Enlargement Myelopathy

Affect myotomes of legs and include sacral myelopathy

19

Thoracic Myelopathy

Causes a horizontal line on abdomen, where below line you have dysfunction
Distal muscles weaker than promixal

20

Cervical enlargement Myelopathy

Deficits of thoracic myelopathy as well as deficits in myotomes of the arms
6th- lower motor neuron to biceps and myotome, UMN to tricepts

21

Upper Cervical Myelopathy

Dysfuncticuase horiztonal line encircling neck with somatosensory and UMN abnormality to below.
Look for Pronator Drift, clumsy quick motor movement. Respiratory weakness

22

Unilateral Myelopathy (Brown Sequard)

1)Ipsilateral lower motor abnormality at site of lesion
2)UMN abnormality of all ipsilateral myotomes below lesion
3) Loss of Vibration, Proprioceptin, Fine tounch ipsilateraly below lesion
4) loss of pain/ temp and crude touch, 2 below contalaterally
5)

23

Anterior Myelopathy

Due to anterior spinal blockage
1) Bilateral LMN loss to ventral horn
2) Loss of spinothalmic tract 2 below lesion
3) Initial Shock, then UMN sydrome takes over
4) Autonomic Functions lost below lession

24

Posterior Myelopathy

due to posterior spinal artery blockage
1) Dorsal Column lost.
2) total IPSILATERAL anesthesia at level.
3) possibly affect to descending motor

25

Medial Cerebellar Syndrome

Symptoms-
1) Ataxia, dysarthria, vertigo, nystagmus, nausea

26

Lateral Cerebellar Syndrome

Ataxia
Dysmetria
intentional tremor of ipsilateral limb
