Tetraplegia, also known as quadriplegia, is defined as the dysfunction or loss of motor and/or sensory function in the cervical area of the spinal cord. [1] A loss of motor function can present as either weakness or paralysis leading to partial or total loss of function in the arms, legs, trunk, and pelvis.
cerebellar ataxia a gait with a broad base; the patient falters to the side of the lesion ; inability to coordinate fine motor activities (intention tremor), e.g. "past-pointing" (pointing beyond the finger in the finger-nose test) inability to perform rapid alternating movements (dysdiadochokinesia), e.g. inability to rapidly flip the hands
Incomplete lesions of the spinal cord: Central cord syndrome (top), Anterior cord syndrome (middle), and Brown-Séquard syndrome (bottom) Central cord syndrome , almost always resulting from damage to the cervical spinal cord, is characterized by weakness in the arms with relative sparing of the legs, and spared sensation in regions served by ...
Spastic quadriplegia, also known as spastic tetraplegia, is a subset of spastic cerebral palsy that affects all four limbs (both arms and legs). Compared to quadriplegia , spastic tetraplegia is defined by spasticity of the limbs as opposed to strict paralysis .
The Hangman's fracture which is a fracture of the C2 vertebral body or dens of the cervical spine upon which the skull base sits to allow the head to rotate, can also be associated with atlanto-occipital dislocation. Despite its eponym, the fracture is not usually associated with a hanging mechanism of injury.
Conversely, a lower motor neuron lesion affects nerve fibers traveling from the anterior horn of the spinal cord or the cranial motor nuclei to the relevant muscle(s). [ 1 ] Upper motor neuron lesions occur in the brain or the spinal cord as the result of stroke , multiple sclerosis , traumatic brain injury , cerebral palsy , atypical ...
The patient may become paralyzed on the same side as the lesion causing the pressure, or damage to parts of the brain caused by herniation may cause paralysis on the side opposite the lesion. [11] Damage to the midbrain , which contains the reticular activating network which regulates consciousness , will result in coma . [ 11 ]
A lower motor neuron lesion is a lesion which affects nerve fibers traveling from the lower motor neuron(s) in the anterior horn/anterior grey column of the spinal cord, or in the motor nuclei of the cranial nerves, to the relevant muscle(s).
