A therapist on the ward says: "The woman uses the  ball chair on her own initiative several times a day; especially when she needs to be calmed and get her thoughts gathered. She describes that it helps her to find peace during the day without having to go to bed. She finds that the combination of using the Protac Ball Blanket^® at night and the Protac SenSit^® ball chair during the day is completely optimal for her. In the ward, it is experienced that the ball chair can help prevent and limit her tendency to become agitated and angry during the day. She is observed, among other things, to use it before and after she goes to meetings or conversations. In previous hospitalizations she has been mechanically restrained with a fixation belt, but this has not been necessary during this hospitalization".
