Upper Motor Neuron vs Lower Motor Neuron?
UMN - LMN
Spastic paralysis - flaccid paralysis
No atrophy - Severe atrophy
Deep tendon reflex is increased - DTR is absent
Positive babinski sign - absent babinski sign
Absent superficial reflex - present sup reflex
No fasciculation and fibrillation - fasciculation and fibrillation could be present
Spasticity (clasp knife) - hypotonia
DİPNOT: Spasticity and rigidity are hypertonia types therefore they are not the same thing
Where does rigidity during movement originate from?
It originates from extrapyramidal system abnormality.
Spasticity (clasp knife) vs rigidity?
Spasticity–> increased tone of flexors of upper limb and extensor of lower limb
Rigidity–> equal resistance in both antagonists or agonists
What is myostatin mutation?
Myostatin-related muscle hypertrophy is a rare genetic condition characterized by reduced body fat and increased skeletal muscle size. Affected individuals have up to twice the usual amount of muscle mass in their bodies, but increases in muscle strength are not usually congruent.
Çocuklarda görüldüğünü hatırla, bir de kalpte hipertrofiye yol açabildiğini.
Match the motor strength abnormalities with their definitions
Quadriplegia
Hemiplegia
Paraplegia
Monoplegia
Quadriplegia - weakness in 4 limbs
Hemiplegia - weakness in one arm and leg on the same side
Paraplegia - weakness in both legs but no arms
Monoplegia - weakness in one limb
Which tractus is related with these followings: numbness, tightness, pins and needles, tingling or burning sensation in the face limbs or trunk
Corticospinal or spinothalamic?
Spinothalamic.
Which tractus is related with spastic walking?
Corticospinal
(Pyramidal tract cs tracti kapsar o nedenle pyramidal da denebilir)
Which tractus is related with these followings: weakness, stiffness heaviness or dragging of arms or legs
Corticospinal
(Pyramidal tract cs tracti kapsar)
Which type of paralysis is seen in internal capsule level?
Evenly distributed contralateral hemiplegia and central facial paralysis
Hemisensory loss could be present or not.
Fill the blanks with ipsilateral or contralateral hemiplegia
Cortex -
İnternal Capsule -
Brain Stem -
Spinal cord -
Cortex - contralateral
İnternal Capsule - contralateral
Brain Stem - crossed hemiplegia, ipsilateral CN palsy + contralateral hemiplegia or sensory loss
Spinal cord - A) Complete transverse spinal lesions –> 1) motor lesions 1-a) cervical cord lvl, quadriplegia 1-b) thoracal cord lvl, paraplegia 2) Sensory signs, a level of sensory loss below lesion 3) Autonomic, sphincter loss
B) Hemisections (Brown sequard syndrome)
Below the lesion –> contralateral loss in pain and temprature
İpsilateral UMN weakness n loss of proprioception
what is pyramidal tract?
The pyramidal tracts are part of the UMN system and are a system of efferent nerve fibers that carry signals from the cerebral cortex to either the brainstem or the spinal cord. It divides into two tracts: the corticospinal tract and the corticobulbar tract.
what is gowers sign and which disease is almost always associated with it?
Weakness in pelvic girdle, therefore the child uses hands to push his legs to stand.
Almost always associated with Duchenne muscular dystrophy
Why there is + babinski sign in UMN lesions?
Due to reflex arch. Mostly corticospinal tract s upper motor neurons inhibit the lower. So, if upper motor neuron is inhibited, the lower motor neurons cause accentuated reflex which causes + babinski reflex.
What does ‘‘Hemi’’ sensory loss indicate?
CNS disease, likely involving either the cortex or the thalamus.
What does Crossed deficits (affecting the face and the body on the opposite side) indicate?
brainstem disease.
what does Deficits involving both sides of the body below a certain level (e.g., T5) indicate?
spinal cord disease
What does A spinal cord level with “sacral sparing” indicate?
intraparenchymal spinal cord pathology
What does A spinal cord level without “sacral sparing” indicate?
myelopathy due to external pressure.
