Lego Therapy is a programme aimed at children with Autistic spectrum disorder (ASD) involving regular structured play therapy through Lego activities. Children participating first learn a set of clear rules and develop Lego brick building skills, including collaborative building, in individual therapy. They are then introduced to a group of peers, which meets on a regular basis (preferably weekly) for around 90 minutes to engage in collaborative Lego building activities and other projects tailored to their skill level. The team works together to assemble the project with an emphasis on verbal and non-verbal communication, joint attention and task focus, collaborative problem-solving, sharing and turn-taking (switching roles during the task). During the Lego system therapy sessions, social conventions can be directly instructed or prompted. For example, if two peers are physically fighting, the supervisors can redirect the children to use language, negotiation and compromise to settle their dispute.
LEGO Therapy falls within the broad class of 'Play Therapy' within ASD research. The goal is that through play therapy, children should learn to communicate with others, express feelings, modify behaviour, develop problem-solving skills, and learn a variety of ways of relating to others.
Lego Therapy has not been included in any systematic reviews into the effectiveness of educational programmes.
