The purpose of the study is to examine the relationship between the location of the initial onset of back pain as revealed by the subject's pain drawing and the site of maximum muscle tension at rest, while jaw-clenching and during a cold stressor, in men and women. Subjects were 30 males and 30 females divided into three groups of 10 males and 10 females each and designated according to back pain history as no back pain (NBP), upper back pain onset (UBP) and lower back pain onset (LBP). Six bipolar, bilateral electromyographic (EMG) recording sites were instrumented on each subject. EMG levels were recorded from the forehead, forearm, upper back, lower back, thighs and ankles under conditions of rest, jaw-clenching and a cold stressor. Seven hypotheses predicted that EMG levels would distinguish groups and gender of the subjects and that interactions would exist between site of pain onset and EMG elevations.
