Paraplegia and quadriplegia have some differences in concept, etiology and clinical manifestations.
1. Concept: Paraplegia refers to a transverse lesion in the higher level segment of the spinal cord, usually the second thoracic vertebrae and above, resulting in paralysis as paraplegia. Quadriplegia refers to bilateral paralysis of the upper and lower extremities, mainly upper and lower motor neuron paralysis.
2. Etiology: Paraplegia is mainly caused by spinal cord trauma, spinal cord degeneration, spinal cord compression, and transverse lesions in the high spinal cord, resulting in abnormal function. Quadriplegia can be seen in cerebral lesions, cervical myelopathy, peripheral neuropathy, and muscular lesions. Spinal cord lesions can also lead to quadriplegia.
3. Clinical manifestations: Paraplegia presents with complete loss of sensory and motor functions below the injury level, autonomic dysfunction, spinal shock, etc. The extent of the lesion depends on the location of the injury. Quadriplegia can be characterized by muscle weakness or complete inactivity of the limbs, and loss of sensory function of the limbs can occur.
There are more differences between paraplegia and quadriplegia. If you feel unwell, it is recommended that you seek medical attention and standardized treatment.
