Introduction

Introduction Limb twitching refers to the involuntary twitching of limbs caused by various reasons. All convulsions, pulls, or flexions and extensions that cannot be controlled by the limbs are in the category of convulsions. It manifests as involuntary contraction of the striated muscle. Commonly seen in the clinic are the following: convulsions, tonic convulsions, tremors, dance-like movements, twisting of the hands and feet, twitching of the muscles, habitual convulsions. Chinese medicine believes that the cause of convulsions is mainly caused by heat and poison, wind and yang disturbance, wind and phlegm, and blood loss. Common in brain diseases, head injuries, rickets, convulsions in children, tetanus rabies and other diseases. Clinically, when the disease with convulsions as the main disease is still uncertain, it can be diagnosed as a preliminary diagnosis and dialectical treatment.

Cause

Cause

High fever, epilepsy, tetanus, rabies, calcium deficiency, etc. can cause cramps, which are systemic, and localized such as gastrocnemius (commonly known as calf), often due to rapid exercise or work fatigue or severe twisting of the ankle Caused, often appearing while lying down or sleeping.

There are many causes of convulsions, and there are many manifestations of symptoms. The main ones are: fever, fever, constipation, snoring in the throat, yellowing, yellow greasy moss, thirst, constipation, bloating, rash, tongue, irritability , bitterness, bitterness, insomnia, and blood deficiency, frequent convulsions, frequent convulsions, sputum, sputum, poor appetite, abdominal distension, cold limbs, loose stools, closed jaws, angulation, The whole body is paralyzed, the upper and lower limbs are twitching, the attack is not regular, and the mind is awake.

Nervous system examination

1, the body tonic convulsions: body muscle rigidity, bursts of twitching, angulation of the horns (head back, the whole body is curved back and bowed), eyes up or gaze, unconscious.

2, limited convulsions: only local muscle twitch, such as only one side of the body twitch, or facial muscle twitch, or finger, toe twitch, or eyeball rotation, nystagmus, blinking action, gaze and so on. Most of them are unconscious. The fashion of the above ventilating can be a few seconds or a few minutes, in severe cases, several minutes or repeated episodes, and the convulsion lasts for more than 30 minutes.

3, febrile seizures: mainly seen in children from 6 months to 4 years old when the high heat occurred in the wind. The febrile seizures are short-lived, and the recovery is quick after the pumping. Most of them occur in the early stage of fever. In a fever of the disease, there is often only one episode of convulsion, which can rule out diseases and other serious diseases in the brain. The EEG is normal.

Diagnosis

Differential diagnosis

Differential diagnosis of limb twitching:

1, high fever: fever is a common symptom of a variety of diseases. High Fever is clinically critical. Normal body temperature in children is usually measured by anal temperature of 36.5 ~ 37.5 ° C, and temperature of 36 ~ 37 ° C. Under normal circumstances, the temperature of the sputum is 0.2 to 0.5 ° C lower than the mouth temperature (sublingual), and the temperature of the anus is about 0.5 ° C higher than the temperature of the sputum. Although the anus temperature is more accurate than the temperature, it is often based on various reasons. If the temperature exceeds 37.4 ° C and the body temperature fluctuates above 1 ° C during the day, it is considered to be fever. The so-called low heat means that the temperature is 37.5 ° C 38, the moderate heat is 38.1 ° 39 ° C, the high heat is 39.1 ~ 40 ° C, and the super high heat is 41 ° C or more. Long-term fever is caused by fever for more than two weeks.

2. Epilepsy: Epilepsy is a chronic disease in which sudden abnormal discharge of brain neurons leads to transient brain dysfunction. Epileptic seizure refers to the clinical phenomenon caused by abnormal brain neurons and excessive hypersynchronous discharge. It is characterized by sudden and transient symptoms, and there are various manifestations of abnormally discharged neurons in the brain. It may be a sensory or autonomic nerve with or without a change in consciousness or alertness.

3. Tetanus: An acute specific infection caused by tetanus invading human wounds, growing and reproducing, and producing toxins. Tetanus is a long-established infection of Clostridium tetani, an acute specific infection caused by invasion of human wounds, growth and reproduction, and production of toxins. Tetanus and its toxins cannot invade normal skin and mucous membranes, so tetanus occurs after injury. All open injuries have the potential for tetanus.

4. Rabies: Rabies, also known as rabies, is an acute viral infection that invades the central nervous system. All warm-blooded animals, including humans, may be infected. It is mostly obtained by biting animals. It is generally believed that mad dogs with white foam on the mouth bite into the infection. In fact, cats, white raccoons, raccoons, skunks, foxes or bats may also be sick and contagious. Diseased animals often become very savage, and the virus in the saliva enters the next patient from the bite wound.

5. Calcium deficiency: The blood calcium of normal people is maintained at 2.18-2.63 mmol/L (9-11 mg/dl). If it is below this range, it is considered to be calcium deficiency. However, for the elderly over 60 years old, due to physiological reasons, the long-term compensatory increase of parathyroid hormone in the elderly has caused "calcium moving" and increased blood calcium. Thus, the measurement results can not truly reflect the calcium content in the body.

6, gastrocnemius tendon: gastrocnemius tendon, that is, "calf cramps." It is the most common type of painful phlegm. It is characterized by a sudden onset of gastrocnemius muscles, such as tonic, phlegm, and pain, such as twisting. It lasts for tens of seconds to several minutes or more, and its pain is difficult to name.
