What is leg crossing and rubbing syndrome, and how should it be managed?

Leg crossing and rubbing syndrome, also known as "jactatio legum" or "leg-clamping syndrome," is a behavioral disorder in children characterized by excitement induced through squeezing the legs together. It may be associated with neurotransmitter dysfunction, and with appropriate treatment, favorable outcomes are usually achieved.

The cause of leg-clamping syndrome is not fully understood, and there is no standardized treatment approach. During episodes, children typically extend and tightly cross their legs while performing rhythmic rubbing movements. Their hands may grip objects tightly or clench into fists. Boys may experience penile erection, while girls may exhibit increased vaginal discharge. Symptoms such as facial flushing and sweating may also occur. If interrupted during an episode, the child may become agitated or start crying. Identifying and addressing underlying triggers is essential for treatment. For example, if pinworms are present, medications such as antipinworm ointment or zinc oxide ointment may be used under medical supervision. In cases where symptoms are prolonged and frequent, medications such as tiapride hydrochloride tablets or haloperidol tablets may be prescribed under a doctor's guidance.

In addition, parents should avoid blaming children who have leg-clamping syndrome, as this could lead to psychological issues. During episodes, it is important to divert the child’s attention—take them out to play or engage in other activities. Encourage healthy hobbies and help establish good daily routines.
