Abstract
The literature addressing relaxation training for retarded individuals is limited. Adding to the controversy over the benefits of relaxation training is the failure of many researchers to document levels of relaxation through physiological measures. The following single-subject study was designed to determine if relaxation techniques could be learned by a hyperkinetic, moderately retarded child based on a predetermined criteria, and the extent to which these techniques resulted in quantifiable muscle relaxation. The child was able to learn the relaxation techniques to criteria within five sessions. Reduced levels of muscle tension as indicated by an electromyogram were evident during relaxation training sessions when compared with baseline sessions. Implications of these techniques for classroom use are discussed.
