Introduction

Introduction Writing snoring is due to occupational factors for a long time engaged in fine hand movements, resulting in hand muscle spasm, a symptom group mainly based on writing dysfunction. For example, teachers, editors, secretaries, writers, painters, calligraphers, scribes, drafters, typists, telegraphers, and players. This disease occurs in young and middle-aged people. The exact cause is still unclear, mainly showing that the fingers are inflexible and uncoordinated; the hand muscles are exploding or the hands are vibrating or even the muscles of the whole arm are vibrating, which makes the function of the hands impede and cannot be done by hand.

Cause

Cause

This disease is an occupational disease of a professional who has been working fine by hand for a long time, and is a good cause for young and middle-aged people. The exact cause is still unclear, mainly showing that the fingers are inflexible and uncoordinated; the hand muscles are exploding or the hands are vibrating or even the muscles of the whole arm are vibrating, which makes the function of the hands impede and cannot be finely worked by hand; Typical and intuitive to see is difficult to hold a pen, writing is skewed, heavy can not hold the pen and writing. This condition is often caused by physical fatigue (especially hand fatigue) or stress. It is estimated that it has a certain relationship with the degenerative changes of basal ganglia cells; it is closely related to mental factors (tension, fear, etc.).

Blood electrolytes, drugs, trace elements and biochemical tests, middle-aged and elderly people are prone to suffer from neurological diseases such as Parkinson's disease or cerebellar ataxia, and symptoms such as finger twitching or tremor may also occur after getting sick. Patients with dysentery are quick-thinking, face-free, normal, no muscle atrophy, sensory presence, normal reflex, and no abnormal CT scan of the brain, which is helpful for differential diagnosis.

1. CT and MRI examinations are meaningful for the differential diagnosis of intracranial diseases.

2. Electromyography examination is meaningful for differential diagnosis.

3. Genetic analysis is important for the identification of certain hereditary dystonia.

Diagnosis

Differential diagnosis

Primary writing sputum is generally considered to be a variant of idiopathic tremor because the frequency of tremor is similar. Primary tremor is accompanied by mild upper limb or motor tremor, and idiopathic tremor Effective drugs can also be used for primary writing tremors.

The onset of idiopathic tremor can only be manifested as unilateral tremor, but as the disease progresses, it can eventually develop into bilateral symmetrical whole body tremor. Primary writing sputum, especially task-inducing, usually remains relatively stable and remains confined to the tremor of the hand.

Primary tremor is also considered to be a variant of writing sputum, both of which are task-specific. To a certain extent, writing also shows a large tremor. The age of onset of writing sputum is 10 to 20 years younger than that of primary tremor. Blood electrolytes, drugs, trace elements and biochemical tests are helpful for differential diagnosis.
