Applied muscle relaxation” is traditionally used to describe the relaxation of muscles by contracting a muscle, holding the contraction, and then releasing tension. This might also be called “contract-release muscle relaxation.” Another method of muscle relaxation, such as that used in yoga, involves stretching a muscle by forced elongation and then holding the forced elongation a certain time, then releasing it. This might also be called “elongation-release relaxation” or “stretch-release relaxation.” CA Multiplex CBT teaches both applied muscle relaxation (i.e., “contract-release” relaxation) and applied muscle stretching (i.e., “elongation-release” relaxation), but emphasizes elongation-release relaxation, that is, yoga-type stretching. Traumatized patients have multiple symptoms induced by muscle tension. Examples of sensations caused by muscle tension include joint soreness, muscle soreness, and headache. Additionally, as discussed in the Introduction, applied muscle stretching allows for the introduction of phrases and images that promote a positive self-image of flexibility and prime to being flexible. These are embodied metaphors.
