Partial limb twitching

Introduction Local limb twitching is common in local convulsions, also known as habitual spasms, which are sudden contractions of a group of muscles. This type of action is rapid and involuntary and often repeated. Sometimes the appearance seems to be completing an action, and it is actually purposeless. It is one of the common types of neurosis in children and is rare in adults. Physiological local convulsions can be seen in the transitional phase of normal people from waking to sleep. If you have conjunctivitis or foreign body into the eye caused by blinking action, it begins to have protective significance, and later fixed into a blink twitch.

Cause

There are many reasons for this, mainly in the following three categories:

1 It has a protective meaning and becomes an unnecessary habitual convulsion in the future. If you have conjunctivitis or foreign body into the eye caused by blinking action, it begins to have protective significance, and later fixed into a blink twitch.

2 by imitating the actions of others.

3 various acute mental factors such as being frightened, being beaten, sudden death of a loved one, and poor academic performance.

Because children's brain motion analyzers are highly excitatory, they are prone to convulsive reactions, and such motion-induced reflexes are rapidly formed and easily fixed, becoming pathologically inert reactions.

Local tic disorder often occurs in children 4 to 6 years old, and boys are more common. The types of twitches are varied. The most common are facial muscle twitching such as squeezing eyes, cavities, making some strange phase; followed by neck and limb twitching such as head shaking, nodding, squeaking in the throat, twisting the neck, shaking the arm, shaking Legs, etc. The convulsions of the same sick child are relatively fixed and rigid, but they can also show a combination of various convulsions. Some patients have some convulsions that can occur at different stages. Children with tics can be accompanied by other neurological symptoms such as restlessness, night terrors, restlessness, and enuresis. Children's pre-disease personality is often characterized by excitement, arbitrariness, irritability, and stubbornness.

Differential diagnosis

Local convulsions are functional and originate from mental factors, but similar actions can be found in chorea, epilepsy or other brain organic diseases and should be identified. It is often misdiagnosed as chorea in clinical practice. The action of convulsions is sudden, rapid, rapid, and often repeated in the same fixed form, while chorea movements are gradual, with longer duration, large amplitude, irregular movements, and often With signs of rheumatic fever. With regard to the identification of this disease and myoclonic epileptic jerk, the latter has typical clinical features: the head is bent, the two upper limbs are stretched, and the two thighs are flexed to the abdomen; the convulsions can be controlled for a while under voluntary efforts. Excitement is aggravated, while children with myoclonus epilepsy are powerless; and there is an abnormal EEG at the time of onset. Identification of multiple tics with organic origin.
