The common “childhood leg rubbing syndrome” in children often shocks parents, which is one of the psychological behavior abnormalities, i.e., a behavior disorder that causes excitement in children by rubbing their legs, which we also call “emotional cross-leg syndrome”. Children with leg-rubbing syndrome have normal intelligence and are alert when they have an attack, mostly before bedtime, after waking up or while playing. During seizures, sweating, girls like to sit on hard objects, press their hands on their legs or lower abdomen, straighten and cross their lower limbs, make fists or grab things to make force; boys mostly show lying on the bed, rubbing back and forth, or similar performance as girls. Girls have episodes of vulvar congestion, increased secretion or increased labial pigmentation; boys have erect penis, slightly congested urethra, and mild edema. Fan Hui, Department of Pediatrics, The First Affiliated Hospital of Henan College of Traditional Chinese Medicine, believes that children’s leg rubbing syndrome is a result of local stimulation of the vulva to form recurrent habits, but because some episodes can be as young as 2 months of age and have not yet reached the habit-forming stage, or the symptoms do not improve according to vulvodynia or pinworm treatment, and the dopamine blocker has certain efficacy, so it is presumed that it may be due to the metabolic disorder of the choline system, causing hyperdopamine function. Some studies have also suggested that children with seizures have disorders of sex hormone levels. Although the etiology of the disease is unknown and the treatment is not uniform, psycho-behavioral treatment methods should be used to relieve the child’s psychological stress, provide more affection, make him happy, and encourage him to participate in various play activities. During seizures, the child’s attention can be distracted by interesting stimuli, and measures such as letting the child fall asleep quickly when tired and getting up immediately after waking can reduce seizures. In addition to daily washing, infants should also use diapers or diapers during daytime play, and wear closed-file pants as early as possible to protect the perineal skin and avoid infection. EEG should be done only if the seizure manifestations are to be differentiated from epilepsy. Leg rubbing syndrome in children mostly resolves gradually on its own with age, so parents need not worry or blame their children.
