Introduction

Introduction Dance-like involuntary movement is a clinical manifestation of involuntary movement. Involuntary movement or abnormal movement is an involuntary contraction of a part of a muscle, a muscle or a certain muscle group. It refers to the skeletal muscle movement in which the patient has a clear consciousness and cannot control it by himself. Clinically common are fasciculation, muscle fiber twitching, convulsions, convulsions, myoclonus, tremors, dance-like movements, hand and foot movements, and twisting sputum. More common in children and adolescents, especially women aged 5 to 15 years old. The incidence of adolescents has declined rapidly, and occasionally adult women have developed symptoms, mainly pregnant women. Encephalitis, diphtheria, chickenpox, measles, whooping cough and other infections, systemic lupus erythematosus and carbon monoxide poisoning can cause this disease.

Cause

Cause

Choral disease is a common cause of this disease, often occurring after streptococcal infection, and is a neurological symptom in acute rheumatic fever. The lesion mainly affects the cerebral cortex, basal ganglia and cerebellum, which is caused by dysfunction of the extrapyramidal system. The clinical features are mainly involuntary dance-like movements.

diagnosis:

1. convulsions: muscles are rapid, repetitive, clonic or tonic, unintentional contractions, often one or more muscles are produced at the same time, sometimes in the facial or limb symmetry, the amplitude is large and not limited, more than one The spread to him, the frequency is not equal, the rhythm, the internal and external factors of the receptor, accompanied by physical discomfort and other abnormal feelings, objective examination without abnormalities.

2. : Intermittent or persistent involuntary contraction of muscles or muscle groups due to abnormal excitation of motor or neuromuscular muscles of the brain or spinal cord. Some sputum can be associated with myalgia, myotonia and or involuntary movements and head, neck, limb, torso deformity. The rhythmic muscle contraction continues, the muscle relaxation is called the clonic tendon; the longer-lasting muscle contraction is called the tonic tendon. Most cockroaches fall into this category.

3. Tremor: It is the involuntary and fast rhythmic movement of the joint caused by the alternating contraction of the active muscle and the antagonistic muscle. This movement can have a certain direction, but the magnitude of the amplitude varies, with the most common hand, followed by the eyelid, Head and tongue.

4. Myoclonus: For sudden onset of muscles or muscles, short lightning-like involuntary contractions. Can be seen in normal people, pathological myoclonus is divided into rhythmic and non-rhythmic, the former is more common.

5. Dance-like movement: It is a kind of rapid involuntary movement with no purpose, no omen, irregular, asymmetrical, and varying amplitude. The head and face dance movements are characterized by wrinkling, blinking, pouting, involuntary retraction of the tongue, shaking the head and shaking the brain and other fleeting weird activities. Often affecting speech, in the body manifested as a large movement without a certain direction, it is often difficult for patients to maintain a certain posture.

6. Hand and foot hyperactivity disorder: also known as fingering movement. It is characterized by myotonia and slow tonic flexion and extension exercises of the hands and feet, which can occur in the upper limbs, lower limbs, face and head. Usually the upper end of the fat and the face are most obvious. The patient's fingers often have irregular "creep-like" hyperkinetic movements, the metacarpophalangeal joints are overstretched, and the fingers are twisted, which can be in a "Buddha"-like special posture. Increased muscle tone involved in hyperkinetic movements. When the lower limbs are involved, walking is difficult, the toes are twisted, and the hallux is spontaneously dorsiflexed. The patient presents a variety of bizarre involuntary movements. The tongue stretches out from time to time and sometimes retracts. The head twists and twists to the left and right sides, sometimes the pharyngeal muscles are involved and the difficulty of swallowing and articulating occurs. These involuntary movements are relieved when they are quiet, completely stopped during sleep, and are aggravated when they are nervous or free to move, but they feel normal and their intelligence may decrease.

7. Twisting sputum: Also known as deformed dystonia, torsional dystonia, is the acromion of the trunk. Clinically, dystonia and the proximal or extremities of the extremities are characterized by distortion of the longitudinal axis of the body. The muscle tension is increased during the torsion and normal when the torsion is stopped. Other involuntary movements include unilateral throwing, muscle fiber tremor, fasciculation, and muscle fibrillation.

Diagnosis

Differential diagnosis

Differential diagnosis: Involuntary movement is a kind of involuntary movement with no purpose, no regularity, asymmetry, and variable amplitude. The head and face are characterized by strange and varied eyebrows, eye-opening, squeaking, shaking their heads, etc. When the tongue is extended, it cannot maintain a certain tongue position; it often affects talking, chewing, and eating. In the limbs, there is a large movement without a certain direction, rapid flexion and extension of the upper limbs, lifting, rapid flexion of the lower limbs, abduction, adduction, and flexion of the toes from time to time, etc., it is often difficult for patients to maintain a certain posture.

Dance-like sports are seen in:

1 Infectious chorea: small chorea, a disease that is more common in children, often a manifestation of acute rheumatism, which occurs in pregnant women as gestational chorea.

2 chronic progressive chorea: also known as hereditary chorea, the onset of more than 30 years old, family history and mental symptoms.

3 senile chorea: old age onset, but no dementia and family history.

4 Others: brain diseases such as acute or chronic encephalitis, intracranial space-occupying lesions, cerebrovascular disease, hepatolenticular degeneration and brain degeneration, hypoxia, poisoning (lead, magnesium, mercury, carbon monoxide, etc.) and the whole body Sexual metabolic diseases (such as hypoglycemia secondary to brain damage caused by islet cell tumors), and the use of strong tranquilizers can cause dance-like movements, called symptomatic chorea.
