18-year-old boy with Cerebral Palsy

We have a young man with Cerebral Palsy here at the group home. He has an intellectual disability and is estimated to have a cognitive functional level of 3 - 6 months old. He is a wheelchair user and is passively transported around in his wheelchair. He has bouts of self-harming behavior and periods with many spasms. He very easily becomes insecure and reacts with self-harming behavior and loud noises. He has undergone a sensory integration evaluation that concluded that he craves stimulation of all the proximal senses, but primarily the proprioceptive and vestibular senses.

During therapy, insecurity and self-harming behavior can be alleviated by giving him plenty of proprioceptive stimuli. I do this by passively facilitating movement in the typical tone-reducing patterns, e.g., calm rhythmic movements in hip flexion and rotation over the spine. In addition, I give deep touch pressure on the extremities and vibrations on the chest. With my hands I can keep him relaxed and comfortable in therapy. I would really like him to be able to take this relaxed state home with him.

The Protac SenSit® ball chair and the Protac Ball blanket® Combi have made this wish come true! He has been granted funding for the blanket because it gives him peace at night and makes him more rested when he wakes up. Previously, he would make quite a ruckus at night – rocking from side to side and shouting. A behavior we (staff) have interpreted as inner turmoil and vestibular and proprioceptive self-stimulation (like "blind-rocking") The Protac SenSit® chair he bought himself, and it gives him enough peace to be able to stay in common rooms with his fellow residents without becoming restless and self-harming as used to be the case. He also uses it to “wind down” after training.

6-year-old boy with tendency to be self-destructive

During a 3-month period, the boy has spent approximately 20 minutes in the Protac SenSit® ball chair every day after breakfast and during the morning gathering. The chair is also used spontaneously. His concentration has increased during the morning gathering, he can now keep up with what is happening and is not as disturbing to the other children as he was before. He calms down more. It is evident that he calms down when he sits down in the chair. The mornings when he feels bad, the chair helps him “move on”, “get over it” and have a better day.

13-year-old boy with ADHD

It is obvious that all forms of contact and communication, as well as bodily calmness increase both while and after the boy sits in the Protac SenSit® chair. He seeks out the chair spontaneously and often tries to “pretend sleep” to be allowed to stay in the chair a bit longer. He is clearly calmer, happier and easier to work with when he has been sitting in the chair. He often expresses with a twinkle in his eye: “one day I will snatch the chair and take it home without you noticing".
