Full Definition

Sleep-related rhythmic movement refers to a group of stereotyped, repetitive motor behaviors that occur during drowsiness or sleep, most commonly involving head banging, head rolling, or body rocking. These behaviors typically begin in infancy or early childhood and usually resolve with age, though they can persist into adulthood. The movements occur at frequencies of 0.5-2 Hz and may cause sleep disruption or injury in severe cases, requiring protective measures.
