SCI Flashcards
Incomplete SCI
sensory loss related to damage within specific spinal tracts
classifications
Quadraplegia and tetraplegia- occurs above the thoracic vertebrae (C1-C8)
Paraplegia- occurs at T1 or below
Central Cord Syndrome
incomplete SCI that results in more weakness in the UEs than in the LEs.
-A lesion to the centrally located structures of region, that produces sacral sparing and greater weakness in the upper limbs than in the lower limbs.
neurological and functional classification of SCI
Grade the amount of “key muscle” strength of the body.
- determine the key points of “light touch” and “pin prick” sensation of the body
- the neurologic level of injury is the lowest level on the spinal cord where key muscles test at least 3/5 and sensation intact for this level dermatome
- Functional level lowest segment which strength of key muscles graded at 3+/5 or higher and sensation intact.
Brown-Sequard Syndrome
Hemisection of the cord which produces ipsilateral (same sided) proprioceptive and motor loss and contralateral (other side) loss of pain and temp.
-gunshot knife wound
Posterior Cord Syndrome
Rare, results from compression by tumor or infarction of the posterior spinal artery. Proprioception, stereognosis, two point discrimination, and vibration sense are lost below the lesion.
Anterior cord syndrome
A lesion that produces variable loss of motor function and of sensitivity to pain and temperature, while preserving proprioception, touch and vibration
Conus Medullaris Syndrome
Injury of the sacral cord (conus) and lumbar nerve roots within the neural canal that usually results in nonreflexive bladder, bowel and lower limbs. Sacral segments may occasionally show preserved reflexes.
Cauda Equina Syndrome
Injury to the lumbosacral nerve roots within the neural canal resulting in nonreflexive bladder, bowel and lower limbs.
in both the equina and medullaris are LMN injuries- bladder is flaccid. better prognosis for recovery since it is peripheral and there is regeneration capacity.
