Involuntary Movement Check

Involuntary movement is also called involuntary movement. Refers to the purposeless abnormal movement that the patient cannot control at will. The involuntary movement examination is mainly used to determine whether the extrapyramidal lesion is a lesion. Emotions have a great influence on the results of the examination, so the family members should appease the patient's emotions during the examination so that the examination can proceed smoothly. Basic Information Specialist classification: neurological examination classification: neuroelectrophysiology Applicable gender: whether men and women apply fasting: not fasting Tips: Pay attention to rest a few days before the test, do not overwork. Normal value There were no phenomena such as fasciculation, tremor, hand and foot sputum, hand and foot hyperkinesia, dance-like movement, emptiness, twisting, and myoclonus. Clinical significance Abnormal results: manifested as dance-like movements, torsion spasms, acromegaly, or a group of muscles twitching. Intensified every time when you are emotionally stressed or active, and disappear after falling asleep, mainly in extrapyramidal diseases. People who need to be examined: There are patients with untargeted abnormal movements that cannot be controlled at will. Precautions Taboo before examination: emotional stress, posture, sleep, distraction, quiet rest, fatigue, etc. have a greater impact on involuntary movements, so rest a few days before the examination, do not overwork. Requirements for inspection: 1. The environment should be quiet when inspecting. 2. Emotions have a great influence on the results of the examination. Therefore, the family members should comfort the patient's emotions during the examination so that the examination can proceed smoothly. Inspection process (1) Inspection methods and contents Inspection of involuntary movements mainly depends on visual inspection. Attention should be paid to its location, time, amplitude and rhythm, whether the form of motion is uniform or varied. And directly observe or ask about the effects of voluntary exercise, emotional stress, posture, sleep, distraction, quiet rest, fatigue and other involuntary movements, and then determine the type of involuntary movement. (B) the types of common types of involuntary movements are seen in fasciculation, tremor, hand and foot sputum, hand and foot hyperkinesia, dance-like exercise, emptiness, torsion, myoclonus and so on. 1. Fasciculation refers to the appearance of small, rapid or peristaltic vibrations in a muscle of a patient's body. It can be induced by mild percussion muscles in percussion. It is an important sign of lower motor neuron damage, often used as a basis for identification of neurogenic muscle atrophy and myogenic muscle atrophy. It can be seen in secondary muscle atrophy caused by degeneration of lower motor neurons, such as amyotrophic lateral sclerosis, progressive spinal muscular atrophy, progressive bulbar palsy, and the like. It can also be seen in a variety of other lower motor neuron disorders, such as syringomyelia, polio, intramedullary or extramedullary tumors. 2. Tremor An involuntary, rhythmic, alternating small jitter. According to the relationship between tremor and random movement (1) Resting tremor means that the patient has a series of involuntary and more regular shaking in a certain state of waking and quiet state, and the tremor disappears during sleep. In the case of resting tremor, the hand can be a tremor-like tremor, which can be combined with other types of tremor. Typical resting tremors are found in Parkinson's disease and syndrome, hepatolenticular degeneration, and essential tremor. (2) Action tremor can be posture tremor or intentional tremor. The former patient trembles when holding a certain position, and disappears when it is still; the latter appears at the action, at the end of the movement, the closer to the target obvious. Found in cerebellar diseases, flapping tremors and alcohol, mercury, niacin and other drug poisoning. Also seen in chronic liver disease, early hepatic coma. (3) Senile tremor often manifests as nodding or shaking head movements, generally without changes in muscle tone. Similar to tremor paralysis, but more common in elderly patients with arteriosclerosis. In addition, the slight tremor of the finger is common in hyperthyroidism. 3. The hand and foot muscles are tense when the tetany is attacked. In the upper limbs, the wrist flexes, the fingers stretch, the palmar joint flexes, the thumb is close to the palm and is opposite to the little finger, forming an obstetrician hand. . In the lower limbs, the ankle joint and the toe joint are both flexed. In the interval of the attack, an excitation test can be performed, that is, the patient's forearm is wrapped with a sphygmomanometer cuff, and then inflated to make the mercury column reach a diastolic pressure or more, and when it occurs for 4 minutes, it is called Trousseau sign positive. Found in hypocalcemia and alkalosis. Not suitable for the crowd Inappropriate population: Patients with disabilities on their limbs or disease. Adverse reactions and risks Nothing.
