Somatic tremor mainly includes resting tremor, postural tremor and locomotor tremor, and its symptoms include tongue tremor, hands tremor, lip tremor, head tremor and lower limb tremor. 1. Resting tremor: the tremor occurs in quiet and muscle relaxation, manifested as quiet, reduced during activities, disappeared during sleep, and rhythmic shaking of fingers, about 4 to 6 times per second, “pill rubbing”, and in serious cases, it can occur in the head, jaw, lips and tongue, forearms, lower limbs and feet. It is common in Parkinson’s disease. 2. Postural tremor: it does not occur during casual movement, but when the movement is completed, the tremor occurs when the limbs and trunk are actively kept in a certain posture. The tremor disappears when the limbs are relaxed and becomes obvious when the muscles are tense. Postural tremor is predominantly in the upper limbs, and can also be seen in the head and lower limbs. It is common in idiopathic tremor, chronic ethanol intoxication, hepatic encephalopathy and hepatomegaly. 3. Locomotor tremor: when the body purposefully approaches a certain target, the tremor occurs during the movement, and the closer the target, the more obvious the tremor. The closer the target, the more pronounced the tremor. When the target is reached and the posture is maintained, the tremor sometimes still persists. The tremor is most common in cerebellar lesions, and can also occur in thalamic and red nucleus lesions. The symptoms of body tremor are complex, and a comprehensive examination should be conducted immediately after the onset of the disease, so that targeted treatment can be carried out after a clear diagnosis is made.
