Limb involuntary tremor

In daily life, we often see some elderly people's hands, head, or lower limbs involuntarily tremble or swing back and forth, which has a certain impact on the elderly's life. In fact, because many causes can cause limb involuntary tremor, it should be treated differentially. Tremor refers to the trembling and shaking of the head and limbs, and paralysis refers to the inability of some or all of the limbs to move autonomously. Common in Parkinson's disease.
