The direct, and much of the indirect, evidence supporting the existence psychophysiological mechanisms for phantom limb pain is reviewed. Phantom pain is shown to be a symptom class composed of different, but similarly described problems, each having its own underlying mechanisms. At least some descriptive types of phantom pain probably have mainly(More)
The amygdala is thought to be an important neural structure underlying the "fight-or-flight" response, but information on its role in humans is scarce. The clinical and psychophysiological effects of amygdalar destruction were studied in 2 patients who underwent bilateral amygdalotomy for intractable aggression. After surgery, both patients showed a(More)
This study is the first systematic examination of a trapezius EMG biofeedback training regimen with tension headache sufferers. It evaluated the differential effects of three psychophysiological treatments for tension headache: (1) a standard 12-session frontal EMG biofeedback training regimen (n = 8), (2) a 12-session upper trapezius EMG biofeedback(More)
Surface EMG recordings of bilateral paraspinal muscle tension were measured on 207 subjects (29 non-back pain controls, 20 individuals with spondyloarthritis, 52 with intervertebral disk disorders, 66 with unspecified musculoskeletal backache, 17 with some combination of the above 3 groups and 23 subjects with other types of back pain, including unknown,(More)
The present study examined the psychological test responses of 99 headache sufferers and 30 matched nonheadache controls. Headache subjects were of four types: migraine (n = 26), muscle contraction (n = 39), combined migraine-muscle contract ion (n = 22), and cluster (n = 12). Measures consisted of the Minnesota Multiphasic Personality Inventory, a modified(More)
This study examined the temporal stability of three psychophysiological responses (frontal electromyographic activity, hand surface temperature, and heart rate) recorded over four sessions (days 1, 2, 8, and 28) on 34 subjects, 17 with high Spielberger Trait Anxiety Inventory scores and 17 with low scores. Each session consisted of a 20-minute adaptation(More)
Surface electromyographic (EMG) activity recordings of bilateral paraspinal muscle tension were measured twice on 20 non-pain controls and on 46 low back pain subjects (21 individuals with intervertebral disk disorders and 25 subjects with unspecified musculoskeletal backache) during 6 positions: standing, bending from the waist, rising, sitting with back(More)
We evaluated the effects of an 8-week progressive muscle-relaxation therapy regimen on the headache activity of 10 elderly tension-headache subjects. Posttreatment assessment at 3 months revealed significant decreases in overall headache activity (50% or greater) in 7 subjects. Significant clinical or statistical prepost differences, or both, were also(More)
