Background: This work presents the experience of an Emancipatory action research led at the Therapeutic Center for Adolescents (CThA) at Saint Luc’s Clinics (UCL). Subject and methods: This research focuses on the practice effects of “Pixels” and “Passerelle” workshops at CThA. It is about the use of video games as a therapeutic tool, mobilizing of the symptomatology of the teenager. Results: “Pixels” workshops use playing according to three specific forms: the paper role-play game, the video game, and the cards playing game. Their specificity is that the participative adult shows a regressive ability strong enough to play with teenagers and is very careful to not interpret what takes place within. Conclusions: “Passerelle” workshops demonstrate the link between the teenager’s mind and the use of his own virtual avatar. It allows to evolve from a “play together” to a “talk together”, a moment of symbolization and of being able to stand back in regards to his or her own recreational activities. As a discussion, this clinical illustration of Karl recovering from depression and dependency. This setting for speech allowed him to evolve into an impulse mood and to reconnect emotionally.
