The leg clamping syndrome is a form of masturbation (mostly for women), masturbation is commonly known as masturbation, but masturbation does not necessarily use the hands, the use of leg clamping or leaning on an object (such as bedding, arms, each other’s thighs, etc.) to squeeze the vulva by rubbing, can also produce sexual pleasure. Children produce this instinctive physiological response around the age of 2 to 3, less common after the age of 10; however, once this response is inadvertently discovered, some people will consciously begin to masturbate. Women grow up with a more conservative education, and they have always considered touching their genitals to be a cheap and nasty thing to do, and therefore feel guilty about masturbation. This pressure creates an internal conflict with the pursuit of masturbatory pleasure. In fact, this is anxiety-induced phytodysfunction. From a certain point of view, this “leg-holding” behavior of children is a kind of self-masturbation, a generalized pressure on the external genitalia, but different from the masturbation that occurs during adolescence and adulthood, which is limited to the external genitalia (such as vagina, penis, etc.). This is because children can receive sexual information or stimulation from the outside world, but are unable to realize and understand it internally. Generally, this leg clenching habit in children disappears at a certain age or is replaced by the act of masturbation. It is important to note that this self-masturbatory behavior in children can occur as early as a few months of age. Manifestations include paroxysmal body twisting, facial flushing, sweating, and moaning. Therefore, it often causes parental concern and can also be misdiagnosed as epilepsy, or other serious illness. Triggering factors 1. Excessive parental stimulation of the child’s legs and perineal area, including too frequent cleaning care scrubbing; 2. Local itching and friction caused by pinworms, vulvar eczema or too tight pants; 3. Increased sympathetic nerve stress due to calcium deficiency; 4. Individual children are emotionally unsatisfied due to lack of maternal love or discrimination, and vent their frustration through their own stimulation, etc. Corrective measures found that the child’s leg habit, parents do not have to be overly nervous, because it does not mean that the child is not mentally or spiritually healthy, worry about the child will become bad later, not to mention the child’s behavior to scold and forcibly stop. The parents’ attitude is too strong, but will increase the child’s further reinforcement of this behavior. Parents can, with the help of a doctor, carefully check the child’s body for local irritants, and if they are suffering from pinworms, eczema of the vulva and other diseases, they should be treated promptly. If the above-mentioned negative stimuli are ruled out, parents should help their children in real life. 1, to develop a good habit of children to work and rest on time, do not go to bed too early at night, do not stay in bed after waking up, in order to reduce the chances of children “pinch legs” occurrence. 2, parents should also pay attention to create a good family environment for the child, give the child sufficient warmth and affection. Usually encourage children to participate in more outdoor activities, and try to reduce the time to play alone. 3, when parents find that the child “pinch leg” action will happen, or is happening, parents can pretend as if nothing happened, did not see, the child will pick up and walk, or give some of the children have more attractive toys, cartoons, etc., to divert the child’s attention. If the above methods still do not work, you should go to the hospital to see a doctor in time.
