Movement is a language. For children affected by autism, movement may be the only language they can rely on. Children with autism often have limited verbal abilities, making it extremely difficult for them to reach out to others (Hartshorn et al., 2001). When words fail, dance/movement therapy fosters a child's ability to relate, communicate, and connect on a nonverbal level.
