Abstract
In 30 anxious and tense patients a record was made of symptoms, bodily complaints attributable to muscular over-activity, and muscle tension (by summation of action potentials) in the frontalis, forearm extensors and, in some, the neck muscles. Those with the most clinical manifestations of anxiety and tension were the more muscularly over-active. Head, neck and arm symptoms correlated with significantly higher muscle tension. Onset of headache was accompanied by increased innervation in the frontalis muscle. Tremor and startle were accompanied by significant increases in muscle activity in well-separated areas. The body musculature as a whole probably receives increased innervation in anxiety patients.
