In young children with high leg dystonia, there can be abnormal leg posture as well as twitching of the leg muscles. Symptoms of high leg dystonia in young children include abnormal leg posture, such as crossed legs, which is caused by hypertonia of the adductor muscles of the lower limbs. If the hypertonia is persistent, twitching of the leg muscles may occur. It can also cause dystonia, such as bradykinesia. Increased muscle tone in the legs of young children can cause the patient to be unable to maintain the normal posture and movement of the legs of the body. These symptoms may also be present during sedentary rest. If you find that your child has increased leg dystonia, you should consult a doctor and have an electroencephalogram (EEG), electromyogram (EMG), and other relevant tests performed.
