The Effects of Progressive Muscle Relaxation on the Behavior of Autistic Adolescents:

Five autistic adolescents were trained in the use of progressive muscle relaxation to determine the effects of the relaxation training on task-oriented, disruptive, and stereotypic behavior, in a structured academic session. Each academic session was 12 minutes in length. Prior to each session, the children engaged in one of two activities with the relaxation trainer for 10 minutes, i.e., the practice at relaxation or a Simon-says game. Measures of disruption, on-task, and academic rate were gathered in the 12-minute academic session. In addition, a relaxation checklist was used to determine the extent to which the child was relaxed in the relaxation sessions. The results gave little evidence of differential effects as a consequence of the relaxation procedures on any of the dependent measures. The addition of relaxation cues during academic sessions failed to produce any change in the children's behaviors.
