Infantile masturbation is considered a variant of normal behaviour. The abrupt and spontaneous onset, altered sensorium and autonomic phenomena during episodes may suggest an epileptic fit. Therefore, children with infantile masturbation are often admitted to hospital and undergo unnecessary tests. The purpose of the present study was to provide a detailed description of hand activities in infantile masturbation.
The authors reviewed video recordings of 2 boys and 11 girls with infantile masturbation. Position, movements and activities of hands and fingers during episodes were registered.
Five patterns of hand activities were registered: Fisting (four infants), grasping of toys, furniture or clothing (ten infants), chorea-like "piano playing" hand movements (two infants), pressure over the diaper/genital region (one infant) and bimanual manipulation of items (four infants). Fisting was primarily observed in the younger infants, and bimanual manipulation was primarily seen in the older infants.
Recognizing one or more of the five distinct patterns of hand activities in infantile masturbation may help establishing the diagnosis.
婴儿自慰被认为是一种正常行为的变体。在发作期间突然出现的自发性发作、改变的感觉和自主现象可能提示癫痫发作。因此，患有婴儿自慰的儿童经常住院并接受不必要的检查。本研究的目的是详细描述婴儿自慰时的手部活动。
作者回顾了 2 名男孩和 11 名女孩患有婴儿自慰的视频记录。记录了发作期间手和手指的位置、运动和活动。
记录了五种手部活动模式：握拳（4 名婴儿）、抓玩具、家具或衣物（10 名婴儿）、类似舞蹈的“弹钢琴”手部运动（2 名婴儿）、压迫尿布/生殖器区域（1 名婴儿）和双手操作物品（4 名婴儿）。握拳主要发生在较小的婴儿中，双手操作主要发生在较大的婴儿中。
识别婴儿自慰中一种或多种独特的手部活动模式可能有助于确立诊断。
