In collaboration with Torbjørn Helgesen, who had experience with 3D models and CNC technology, we developed a wooden tool with a concave groove for a marble. You give it to the patient. Who then tilts it so that the marble rolls from one side to the other. Who feel the wooden handle in their hands. Feel the vibration from the marble. Hear it rolling. And follow it with their eyes. The therapist can observe from a distant. Or close enough to physically assist, if needed, or just hand the tool back and forth between sets.

The first patient whom I attempted to use this on, was a young man with Asperger’s syndrome.

We had used the light bar to process memories of a childhood with a controlling and violent father. The first few sessions had gone well. But in the fourth or fifth session he suddenly felt that I was like his father, and that by controlling his eye movements, I was controlling all of him. We had to cancel the treatment that session.

The same thing happened the next session. We tried sound and vibrations, but it made no difference. He still felt I was controlling him. I then brought out the Eymo balance tool, and he agreed to try. With a curious look he tilted the wooden tool and let his gaze follow the marble. A smile appeared on his face. I like it, he said. He had regained control of himself.

The next patient I used it on was an Asian woman with very limited mimicry and body language, which made her difficult to read. It made using the light bar difficult. But with Eymo balance, she revealed her emotions through how she rolled the marble. When she felt helpless, the marble rolled so, so slowly, as if pushing it was an uphill struggle and she just wanted to lie down. When she dissociated, it stopped completely. And when she felt anger, she rolled so quick and hard that the marble smashed back and forth.

Assisting position

Observing position

Eymo balance provides bilateral stimulation of five senses: VISION, HEARING, TOUCH, PROPRIOCEPTION and BALANCE. In addition, the brain’s motoric system is activated with easily executive functions, as well as the basic relational need for cooperation with another human, in this case the therapist. It also increases the patient’s autonomy.

AS A STARTING SIGNAL Hans Petter will say “GO AHEAD” or “WHEN YOU ARE READY”, or just hand the tool over to the patient. As a stop signal, he’ll say “PAUSE” or use his hands to stop the tool. Eventually, many patients prefer to decide for themselves when to start or end the bilateral stimulation.

It is perceived as something primal to hold a tool carved out of wood and make a round object roll. Some say they like the interplay between initiating the movements themselves and seeing the marble moving on its own. Some say they like that it feels playful and unpretentious. It has not yet been tested on children.

Relaxing grip

Thumb grip

Power grip

By alternating between different grips and sitting positions, you can achieve various effects.

RELAXING GRIP: Rest your hands on your thighs and tilt the tool with your fingertips.

THUMB GRIP: Keeping your thumbs by the ends of the groove increases tactile stimulation while reducing noise and increasing speed.

POWER GRIP: A firm grip on the handle can add a feeling of force and increased control.

“It was good to have something to hold on to when I was so afraid,” says one patient. “At least I had control of one thing.”

Holding the ends of the tool also furthers a more open posture, which in turn affects the patient’s bodily reactions and emotions. It can reduce feelings of shame and increase the contact between patient and therapist.

Varying positions between therapist and patient allows for different interactions.

OBSERVING POSITION: The therapist observes from a distance.

ASSISTING POSITION: The therapist sits closer to the patient, so that they may hand the tool back and forth between each set.
If necessary, the therapist can assist with the tilting by indirect physical contact via the tool or direct physical contact by lightly holding the patient’s hands. This allows the therapist to demonstrate the use of the tool before letting the patient try alone.

Presentingthe Eymo

Eymo balance is a new device for trauma treatment. The Eymo is carved out of wood. Spruce is used, which is a lighter type of tree that gives a comfortable grip and more pleasant sound for the marble.
