The relative effectiveness of three techniques used for relaxation training (EMG Biofeedback, Progressive Muscle Relaxation, and Self-relaxation) was compared for 12 subjects who scored high or low on trait anxiety. Dependent variables included change scores based on EMG readings and pulse rate and posttreatment State-anxiety. Pulse rate was significantly affected by the type of treatment, i.e., Progressive Muscle Relaxation produced less decrease in pulse rate than the other two techniques. EMG and State anxiety measures did not differ as a function of treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
