1.What are the risk factors? Uncontrollable factors: age p gender p family history p race, etc. Interventional factors: hypertension p smoking p high blood pressure p high salt diet p obesity p alcoholism p heart disease p diabetes mellitus p transient cerebral blood supply deficiency p mental stress, etc. 2.What functional disorders can be caused by hemiplegia? Motor impairment: The longest seen is paralysis of one limb. In severe cases, the paralyzed limb is completely unable to move on its own, with loss of sensation and no muscle strength, and in less severe cases, the paralyzed side has reduced muscle strength and is less active. Sensory impairment: mainly manifested as pain p temperature p touch p pressure p visual impairment. Language communication disorders: motor aphasia-patients can understand other people’s words, but they can’t express themselves in words; sensory aphasia-patients do not have visual p hearing impairment, but can’t understand their own and other people’s words, and speak 拢拢莶 emblem! Emotional disorders: depression-is the most frequent emotional disorder in patients with hemiplegia, with two peak incidences within 6 months and 24 months after the disease; anxiety disorder-is mostly seen in patients with more severe hemiplegia. Cognitive impairment: Patients’ memory p analyzing ability p thinking ability is significantly reduced, reflexes are slow, and in severe cases, they may lose use p recognition and cannot perform their previous work. 3.How to grasp the timing of rehabilitation? The disability rate of hemiplegia is quite high. If rehabilitation intervention is implemented correctly at an early stage, the disability rate of hemiplegia can be greatly reduced. Generally speaking, the time to start rehabilitation intervention should be 48 hours after the patient’s vital signs are stable and the neurological symptoms no longer develop. Patients with ischemic hemiplegia can be rehabilitated after 1 week of onset and patients with hemorrhagic hemiplegia after 2-3 weeks of stabilization. Passive rehabilitation can only be performed in the acute phase without interfering with resuscitation, such as ensuring correct body position p turning p appropriate passive movement of the limbs, etc. Because of the high possibility of recurrence of subarachnoid hemorrhage in the near future, patients who have not undergone surgical treatment should be observed for about 1 month before cautiously starting rehabilitation training. 4.How to avoid aggravation of hemiplegia? Control known risk factors: Patients with transient ischemic attack p heart disease p diabetes mellitus p hypertension and other conditions should be treated actively. Develop reasonable dietary habits: advocate eating low cholesterol p low fat p low salt p low sugar food, diversify food, and change bad smoking and drinking habits. Perform appropriate medication and physical exercise. Pay attention to the precursors of hemiplegia aggravation: if symptoms such as headache p hemifacial numbness p finger inflexibility p walking instability appear or aggravate, go to the hospital promptly. Prevent complications: such as respiratory tract infection p urinary tract infection p deep vein thrombosis p pressure sores, etc.
