Hemiplegia left arm?

summary

Hemiplegia, also known as hemiplegia, refers to one side of the upper and lower limbs, facial and tongue muscle movement disorders, it is a common symptom of acute cerebrovascular disease. Although patients with mild hemiplegia can still move, when walking, they often bend their upper limbs and straighten their lower limbs. The paralyzed lower limbs walk one step and half a circle. This special walking posture is called hemiplegic gait. Hemiplegia left arm? Let's talk about it

Hemiplegia left arm?

In cortical hemiplegia, the upper limb paralysis is obvious, and the distal part of it is located. If there is cortical stimulation, there are seizures. In parietal lobe lesions, there is cortical sensory disturbance, which is characterized by normal superficial sensation, such as tactile sensation and warm pain sensation, while obvious disturbance of entity sense, position sense and two-point discrimination. The sensory disturbance was obvious in the distal part. Right cortical hemiplegia often accompanied by aphasia, apraxia, agnosia and other symptoms (right side), bilateral subcortical hemiplegia with disturbance of consciousness, mental symptoms. Cerebral cortical hemiplegia generally does not have muscle atrophy, late can have disuse muscle atrophy; But the hemiplegia caused by parietal lobe tumor may have obvious muscular atrophy. Cortical or subcortical hemiplegic tendon hyperreflexia, but other pyramidal tract signs were not obvious. Cortical and subcortical hemiplegia is most common caused by middle cerebral artery disease, followed by trauma, tumor, occlusive vascular disease, syphilitic vascular disease or cerebral embolism caused by heart disease.

After the pyramidal tract was injured in the internal capsule, there was internal cystic hemiplegia, which manifested as paralysis of upper and lower limbs including lower facial and lingual muscles on the opposite side of the lesion. In hemiplegia, the muscles dominated by bilateral cortex are not involved, namely masticatory muscles, pharyngeal muscles, eye, trunk and upper facial muscles. But sometimes the upper facial muscles may be slightly affected, and sometimes the frontal muscles may be weak, showing that the eyebrows are slightly lower than the opposite side, or the orbicularis oculi muscles may be weak, but these disorders are short-lived and soon return to normal. When the anterior 2 / 3 of the posterior limb of the internal capsule was damaged, the increase of muscle tension appeared earlier and obviously. The pathological reflex of extensor muscle was easy to appear. When the anterior limb of the internal capsule was damaged, the muscle stiffness appeared, and the pathological reflex was mainly flexor muscle group. The most common cause of internal cystic hemiplegia is hemorrhage or occlusion of the supply area of lenticular artery in the branch of middle cerebral artery.

Brainstem hemiplegia (also known as crossed hemiplegia) the hemiplegia caused by brainstem lesions is mostly manifested as crossed hemiplegia, that is, unilateral cranial nerve paralysis and contralateral upper and lower limb paralysis. The most common causes are vascular disease, inflammation and tumor.

matters needing attention

(1) Physical exercise can enhance physique, improve disease resistance and delay aging（ 2) Physical exercise can enhance the heart function, improve the elasticity of blood vessels, promote the blood circulation of the whole body, and improve the blood flow of the brain（ 3) Physical exercise can reduce blood pressure, dilate blood vessels, accelerate blood flow, and reduce blood viscosity and platelet aggregation, which can reduce thrombosis（ 4) Physical exercise can promote lipid metabolism, improve the content of high-density lipoprotein in blood, so as to prevent arteriosclerosis. Long term exercise can reduce weight and prevent obesity. Therefore, physical exercise is an important measure to prevent hemiplegia.
