Loss of temperature sensation is one of the symptoms of spinal cord cavernous disease, which is caused by disruption of thalamic fibers in the spinal cord. The formation of a tubular cavity in the spinal cord due to a variety of causes is called spinal cord cavernous disease, and there is often neurogliosis around the cavity. The onset of the disease is relatively slow, clinical manifestations of the affected spinal cord segmental nerve damage symptoms, characterized by pain, temperature sensation loss and disappearance, while the preservation of deep sensation of the dissociative sensory impairment, combined with the damage to the long tracts of the spinal cord motor and neurotrophic disorders. Prevention and care of loss of temperature sensation: 1. Combination of work and rest. Avoid functional exercise, because forced functional exercise will be due to skeletal muscle fatigue, which is not conducive to the recovery of skeletal muscle function, muscle cell regeneration and repair. 2.Keep optimistic and happy mood Stronger long-term or repeated mental tension, anxiety, boredom, pessimism and other emotional changes can make the balance of the cerebral cortex excitation and inhibitory process imbalance, make the muscle jump aggravate, make the development of myasthenia gravis. 3, reasonable diet, maintain normal digestive function patients with spinal cord cavernous myasthenia gravis maintain normal digestive function, reasonable allocation of dietary structure is the basis of recovery, spinal cord cavernous myasthenia gravis patients need high protein, high energy dietary supplements, to provide the necessary substances for the reconstruction of nerve cells and skeletal muscle cells, in order to enhance the muscle force, muscle growth, early use of high protein, rich in vitamins, phospholipids and trace elements of food, and actively cooperate with medicinal diets, such as the mountain, the mountain, the mountain, the mountain, the mountain, the mountain, the mountain, the mountain, the mountain, the mountain. And actively cooperate with the medicinal diet, such as yam, coix seed rice, lotus heart, Chen Pi, tai zi ginseng, lily, etc., but also prohibit spicy food, quit smoking, alcohol. For patients in the middle and late stages, high protein, high nutrition, energy-rich semi-fluid food and fluids are the mainstay, and small meals are used to maintain the nutritional and electrolyte balance of the patients.
