Tension levels from muscles in the forehead (frontalis) and back of the neck (semispinalis capitis) were simultaneously recorded during short term relaxation training with EMG feedback to assess the efficacy of this technique for producing generalized deep muscle relaxation. The degree of association between the activity of the two muscles was measured both with cross‐correlation coefficients and a linear regression technique. The two muscles showed a tendency to covary which did not change during training and was unrelated to which muscle was the source of feedback. These results provide evidence for a moderate degree of association between these muscle groups during relaxation training and suggest that EMG feedback may be more useful in producing general relaxation than was previously thought.
