Spinal cord hemi-cut syndrome
Hemi cut spinal cord syndrome as lesions level, above the ipsilateral motor neuron paralysis, articular muscle vibration Cox missing, contralateral pain and temperature sensation disappeared; adjacent to the lesion, with a considerable segment of lesions, a segmental lower motor neuron paralysis and sensory impairments. Because after cable cut, the focus of the following section, the ipsilateral proprioception and Tinel disappear. As cut pyramidal tract lesions segmental level, the ipsilateral upper motor neuron paralysis; Extrapyramidal EC because the inhibition was blocked, the spinal cord and roots into the role of impulsivity significantly, thereby enhancing muscle tone, Deep hyperreflexia, reflecting toe into toe dorsiflexion. Due to the spinal cord cut off thalamus, in the contralateral, or lesions following a segment or two segments of the spinal cord level, pain and temperature sensation disappeared. Because of the festival cut off root involvement, there ipsilateral segmental feeling disappeared. Since the upper section of the right stimulus, feeling disappeared in the top of a segmental hypersensitivity. As Angle involvement, sympathetic symptoms can occur, as in eight of the neck injury, the ipsilateral face Head and neck skin can be a sign of vascular ataxia syndrome and neck (Miosis, eyes narrow cleft and enophthalmos).
