Electromyographic analysis of relaxed postures.
Six male volunteers assumed either "relaxed" or "unrelaxed" postures, as defined by a Behavioral Relaxation Scale, in seven areas of the body. Electromyographic (EMG) levels in the muscle groups associated with each area were determined for both categories of postures. In all instances, the "relaxed" postures produced significantly lower EMG levels than the "unrelaxed" postures. This indicates that the Behavioral Relaxation Scale is a valid behavioral measure of relaxation. Also, it supports other studies which have shown that direct training in emitting relaxed postures is an effective means of achieving relaxation.
