Weird asynchronous state

Introduction That is, weird walking posture, common in the elderly or young children, the elderly can be presumed to have vascular dementia, the possibility of vascular dementia is very high, the child's strange asynchronous state often has lower limb stiffness, gait instability, horseshoe inversion, etc. May be dystonia.

Cause

May be dystonia.

The lower limbs are stiff, the gait is unstable, the horseshoe is turned over, the standing is unstable, and the steps are short.

Differential diagnosis

The symptoms of the asynchronous state need to be distinguished from the following symptoms:

Cross-threshold gait: The common peroneal nerve is composed of L4-S3, and its damage causes dorsiflexion, abduction and adduction, and obstacles to the toe, as well as anterior and lateral sensation of the lower leg.

Abnormal gait: Gait is the posture of the patient while walking. It is a complex exercise process that requires a high degree of coordination between the nervous system and the muscles, and involves many spinal reflexes and adjustments of the large and cerebellum, as well as the complete coordination of various posture reflexes, sensory systems, and motor systems. Therefore, observing gait often provides important clues to neurological diseases. Different diseases can have different special gaits, but gait is not the basis for diagnosis, but has a reference for diagnosis. Care should be taken to exclude gait abnormalities caused by bone deformities and bone, joint, muscle, blood vessels, skin and subcutaneous tissue.

Auto-Babinske Sign Positive: The Babinske sign is a special spinal reflex that occurs when the spinal cord loses control of the cerebral cortex. When the blunt object is used to scribe the foot, the big toe is bent back, and the four toes are fan-shaped outward. The spinal cord of the positive adult is active under the control of the cerebral cortex motor area. Normally, this reflection is suppressed and cannot be manifested. When the cone system or the extrapyramidal system is damaged and the inhibition is lost, the Babinski sign appears. The Babinski's sign can be examined clinically to determine the function of the pyramidal or extrapyramidal system. Babinski's sign is also positive before the infant's pyramidal tract is not well developed, and when the adult is deeply asleep or anesthetized. Common in dopa-responsive dystonia, it is a rare hereditary disease that occurs in children or adolescents with dystonia or gait abnormalities as the first symptom.

Localized dystonia: dystonic syndrome is called dystonia, which is an inconsistency or excessive contraction of active muscles and antagonistic muscle contractions, which leads to the synthesis of dyskinesia characterized by abnormal muscle movements and postures. The sign is characterized by involuntaryness and continuity. Although it is called dystonia syndrome, the changes in muscle tone are not noticeable, but the abnormal posture posture and involuntary transformation action are noticeable.

Child-type dystonia: deformed dystonia, idiopathic torsion myodystonia, formerly known as deformed dystonia, is a group of more common extrapyramidal diseases characterized by At the beginning of active exercise, the active muscle and the antagonistic muscle simultaneously undergo continuous involuntary contraction, showing a special twist posture or posture. The abnormal movement of this disease begins with local dystonia and gradually develops into systemic dystonia. Due to the early onset of the disease, the disease has recently been called early-onset torsion myodystonia, and the hereditary pattern is autosomal dominant inheritance.
