Studied the effects of the intervention technique of Structural Integration on state-trait anxiety. Matched pairs of Ss were assigned randomly to either the experimental (received rolfing) or control group (N = 48). State anxiety questionnaires were administered beofre rolfing and then again in 5 weeks after rolfing. Results indicated that rolfing caused a decrease in state anxiety when compared to the control group. Results were discussed in terms of the release of emotional tension stored up in the muscles due to Structural Integration.
