Spinal cord injuries Flashcards
Etiology of SCI:
falls, violence, sports, vehicle crashes ***
quadraplegia:
injury between C1 to T1
Parapeligia
thoracic, lumbar, or sacral regions of spine.
Mechanisms of SCI:
85 % are trauma caused. 15% tumors or ischemia. hyper flexion, hyper extension or compression forces applied to the spine
last functioning neurological segment
vertebrae that the patient fractured
myotomes:
each nerulogical segments supplies groups of muscle.(myotomes) COMPLETE C6 would have function of muscles supplied by myotomes C1-C6
Dermatomes:
Area of skin that is supplied by that nerve root. Sensory loss would be expected in the dermatomes below the level of SCI.
Incomplete SCI:
Myotomes and dermatomes that are functioning below the level of the SC injury. Some function and sensation remains below injury.
2 classifications of incomplete:
Central (greater loss of U/E), Lateral (motor loss of one side).
Cauda Equina Lesion:
below L2. (horse’s tail). Loss of sensation betwen legs (thighs) and back of legs. Bladder/ Bowel dysfunction. weak legs.
Stages of recovery:
spinal shock (flacid paralysis), Recovery (spastic paralysis)
Complications:
Autonomic dysreflexia, respiratory problems, decreased vital capacity of the lungs, ulcers.
Recovery:
neuroplasticity (reorganization within the CNS) and neurogenesis
Epidural Stimulation:
extensive electrical stimulation of subjects lower spinal cord mimicking brain signals to create movement. TREADMILL
