Postural tremor is mainly caused by variant physiological tremor, heredity and metabolic encephalopathy, and it is recommended to go to the hospital for examination to clarify the cause of the disease and then carry out targeted treatment to control and improve the condition as soon as possible. Postural tremor refers to a series of random and irregular shaking of a certain part of the body when the patient maintains a certain posture (e.g., keeping the head upright or extending the upper arm forward). The tremor disappears at rest. This type of tremor mostly occurs in the upper limbs and head. 1. 1. Variable physiological tremor: Postural tremor occurs when the regulatory response of adrenergic receptors is increased after the application of epinephrine or during hyperthyroidism, emotional stress, anxiety, panic and fatigue. 2. Genetic factors: Hereditary postural tremor can occur at all ages, and the amplitude of the tremor is related to the degree of muscle tension, which needs to be differentiated from the resting tremor of Parkinson’s disease and the action tremor caused by cerebellar lesions. 3. Metabolic encephalopathy: Hepatomegaly, hepatic encephalopathy, and uremia can also cause a slow-paced, coarse tremor involving the limbs. Postural tremor is a relatively common disease, timely examination and diagnosis in the hospital, according to the guidance of a professional doctor combined with the individual situation of symptomatic treatment, daily life, pay attention to rest to avoid excessive fatigue, maintain a relaxed mood, can effectively alleviate the symptoms, the patient does not have to worry too much.
