Nowadays, we generally use behavioral therapy and cognitive therapy for pinched leg syndrome. Behavior therapy is a way to help children slowly reduce or eliminate these behaviors. This requires the cooperation of three parties: parents, teachers and doctors. The doctor needs to give advice and help, set goals, and develop some behavior assignments based on the child’s situation, the parents, the characteristics of the school, and the child’s personality. It is the parents and teachers who do the actual operation and implementation. The behavioral treatment we suggest is aimed at the original cause of the child’s symptoms. Most of the child’s main learning experiences in preschool are through games, but these games are learned through imitation and interaction, so we do not advocate that the child play alone or watch TV alone, which is not helpful to the child. We advocate a kind of interactive communication, if parents feel you are very busy, you can let the child go next door to the neighbor’s children to play, or downstairs to play with other children in the neighborhood. In this kind of interactive communication, the child will be less bored, and in addition will learn a lot of knowledge. This knowledge is not cultural knowledge, but knowledge of how to get along socially, such as interactive communication, self-confidence, and an ability to understand each other’s emotions. When parents notice this in their child, we can break his boredom by not letting him have too much time alone. Parents have to make some behavior records of their children, of course, the child already knows, understand, parents for this behavior do not hide. For example, the mother should not say “you do not how to do” and so on, you can openly talk to the child, this behavior is not good, mom to help you reduce it together. At the same time, parents also want to do hidden, because the child is very dignified, you can not make this matter public so that many people know, do not let him around the children know, if you know will make the child feel very bad face. Parents can use some small methods, such as small reminders, small dolls, you can put a mark on the doll, you see the doll will find the mother remind you, such as in kindergarten or at home, the child sees the doll, there will be this awareness of being reminded by the mother. Many girls, because there are more girls with this symptom, we advocate that parents tie a very beautiful rubber band on their hands, will not be noticed, because this rubber band can always tie the braid, but when she really wants to do it herself, let her pull that rubber band, to achieve a distracting effect. Others won’t think she’s abrupt and abnormal, and she’ll naturally pay attention to the rubber band on her hand, but this will serve as a self-reminder.
