Throwing action (twitch)

Introduction Throwing action (twittering) is a kind of involuntary movement of the limb, which is expressed as a throwing dance movement, with obvious proximal muscles, which can be divided into single limb throwing movement, side throwing movement and double side throwing movement. It is the clinical manifestation of involuntary movement. The lesion is in the subthalamic nucleus (Luys body) and the structure directly related to it, mostly caused by vascular damage, also seen in encephalitis or brain tumor. In daily life, we often see some elderly people's hands, heads or lower limbs involuntarily tremble or swing back and forth, which has a certain impact on the lives of the elderly. In fact, because many causes can cause limb involuntary tremor, it is necessary to identify the treatment. Tremor refers to the shaking and shaking of the head and limbs. Paralysis refers to the inability of a certain part or all of the limbs to move autonomously. Common in Parkinson's disease.

Cause

The cause of throwing action (twittering) is mostly due to involuntary movement.

The clinical manifestations of involuntary exercise are diverse, and their types and characteristics are described as follows:

1. Tremor: It is the involuntary movement of a certain part of the body that oscillates in a certain direction and varies in magnitude. It is most common in the hands, followed by the eyelids, head and tongue. Tremor can be divided into three types: physiological, functional and pathological.

2. Dance movement: It is an involuntary movement with no purpose, no rhythm, asymmetry, uncoordinated and fast, and varying amplitudes. It is expressed as pouting, blinking, and tongue. The limbs are characterized by a large movement without orientation, rapid flexion and extension of the upper limbs, and rapid flexion, abduction, adduction, and flexion of the toes from time to time. When you continue to shake hands with the patient, you can feel the time. tight. Dance movements are often caused by striatum lesions, especially when the caudate nucleus is involved. Dance movements are common in clinical practice in chorea.

3. Hand and foot hyperactivity disorder: also known as finger movement, characterized by dystonia and slow and irregular torsional movements of the hands and feet, mainly due to damage to the shell nucleus and globus pallidus.

4. Twisting sputum: also known as deformed dystonia, torsional dystonia, lenticular dystonia. It is characterized by involuntary movement of the limb or trunk torsion of the longitudinal axis. It is characterized by dystonia and severe and involuntary torsion of the extremities, trunk and even the whole body. The muscle tension increases when twisted, and normal when the twist stops.

5. Throwing action (twittering): It is a kind of involuntary movement of the limb, which is expressed as a throwing dance movement, which is obvious to the proximal muscles, which can be divided into single limb throwing movement, side throwing movement and double side throwing movement. The lesion is in the subthalamic nucleus (Luys body) and the structure directly related to it, mostly caused by vascular damage, also seen in encephalitis or brain tumor.

Differential diagnosis

Throwing action (twitching) is easily confused with the following symptoms:

Involuntary movement: refers to a pathological action in which the patient has no purpose, involuntary, and uncontrollable in the case of clear consciousness. Involuntary movement can occur in any part of the nervous system, such as the cerebral cortex motor area and its descending fibers, basal ganglia, brain stem, cerebellum, spinal cord, peripheral nerves, and various lesions can be caused. Its performance is diverse, and the involuntary movements are mainly related to the dysfunction of the extrapyramidal system. Common involuntary movements in clinical practice include: tremor, dance-like exercise, partial body throwing, hand and foot hyperkinesia, myotonia, myoclonus, muscle fibrillation, and tendon.

Paroxysmal involuntary movement: mainly manifested as paroxysmal involuntary movement, posture dystonia, balance disorder, dysarthria. Emotional stress and drinking can aggravate seizures. The physical examination during the interictal period was normal.

Dance-like involuntary movement: 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.

Rhythmic and repetitive involuntary movements: Delayed dyskinesia (TD), also known as delayed onset ADHD, persistent dyskinesia, is induced by antipsychotics and is a persistent stereotyped repetitive involuntary movement.

Involuntary tremor of the limbs: In daily life, we often see some elderly people's hands, heads or lower limbs involuntarily shaking or swinging back and forth, which has a certain impact on the lives of the elderly. In fact, because many causes can cause limb involuntary tremor, it is necessary to identify the treatment. Tremor refers to the shaking and shaking of the head and limbs. Paralysis refers to the inability of a certain part or all of the limbs to move autonomously. Common in Parkinson's disease.
