The woman tends to have verbal self-stimulatory behaviors – with a great degree of perseveration of sounds. She is almost insistently singing and loud in conversation with herself. The woman is given Protac KneedMe^® immediately after morning care to prevent escalation of sounds / self-stimulatory behavior. Already at the first trial, it is evident that the knee blanket provides the woman a feeling of calmness; her voice is lower, and she responds more appropriately when she spoken to by others. After using the knee blanket, her facial expression is gentler than usual. The woman now sits with the knee blanket every day and preferably several times during the day.
