The whole body jumps in the clinic generally refers to the muscle bundle tremor, the muscle bundle tremor is mainly divided into physiological factors and pathological factors, pathological factors such as motor neuron disease, calcium deficiency and so on. 1. Physiological factors: myofascial tremor is mainly caused by strenuous exercise and over-excitement of the body, which belongs to the normal physiological response, and appropriate adjustment of the way of exercise does not require special treatment. 2. Pathologic factors: (1) motor neuron disease: the pathogenesis of motor neuron disease is not clear, and it is considered to be related to infectious factors, metal poisoning and nutritional disorders, which will lead to amyotrophic lateral sclerosis, muscle stiffness and weakness, and when severe, it will cause myofascial tremor. (2) Calcium deficiency: Calcium deficiency is mainly caused by the lack of calcium in the body and insufficient exposure to sunlight, which will lead to weakness, irritability, and moodiness, etc. Failure to replenish calcium in a timely manner will lead to myofascial tremor. Myofascial tremor may also be caused by peripheral neuropathy, epilepsy and Parkinson’s disease, etc. Excluding physiological factors, it is necessary to consult a doctor in time to clarify the cause and treatment.
