I. Sensory impairment below the plane of injury are lost. Need to wait until the recovery of spinal shock, sensation can gradually appear. Sometimes in the spinal shock period in the anus and perineum can have partial sensory preservation, indicating that the spinal cord injury is incomplete. Second, the motor function of transverse injury in the spinal cord shock period after the fading of the motor function below the injured segment completely disappeared, but muscle tone gradually increased, hyperreflexia. Some of the injured people in the spinal cord shock period after recovery can gradually appear muscle autonomic activity, but the muscle groups governed by the equivalent of the damaged segment can show tension relaxation, atrophy, tendon reflexes disappeared, etc.. Clinical signs of this lower motor neuron paresis, if found, when there is a localized diagnostic significance. Third, spinal cord shock is a clinical phenomenon of complete flaccid paralysis with loss of various reflexes, sensory and sphincter functions that occurs immediately after spinal cord injury below the injured segment. In cases of minor injuries, this phenomenon can be recovered within a few hours or days, leaving no after-effects. In more severe injuries, however, this phenomenon will persist for a long time, often taking 3 to 6 weeks before spinal cord autonomic activity below the injured segment gradually appears. In spinal shock it is often difficult to determine whether the injury to the spinal cord is a functional block or an anatomical transection. However, the longer the duration of spinal cord shock, the more serious the damage and the worse the prognosis. Fourth, the reflexes of the paralyzed limbs gradually become hyperactive after the shock period disappears, and the muscle tone changes from flaccid to spastic. In cases of complete spinal cord injury, flexion paraplegia can be observed, while in cases of partial spinal cord injury, extension paraplegia can be observed. If the skin of the lower limbs is stimulated, involuntary flexion and urination can be induced, which is called the total reflex. Fifth, bladder function in different periods of spinal cord injury can appear in different types of neurogenic bladder. In the spinal cord shock period manifested as an atonic bladder, when the shock gradually recovered, manifested as a reflex bladder and intermittent incontinence. When the spinal cord recovers to the point where reflexes appear stimulation of the skin of the lower extremities produces involuntary reflex urination. In the late stage, it manifests as a contractile bladder. When the patient develops an overall reflex, it may manifest as an uninhibited bladder.
