The assessment of personality, anxiety and depression in mandibular pain dysfunction subjects.

The search for distinct personality characteristics of mandibular pain dysfunction patients has produced confusing and contradictory results. The present study represents an attempt to clarify this area of research by assessing reliable measures of personality (MMPI), anxiety (Speilberger State-Trait Anxiety Inventory), and depression (Beck Depression Inventory) in ten subjects with a history of facial pain and TMJ sounds. Two control groups, one with TMJ sounds only and other with no history of these symptoms, were matched for sex. The results indicated that the groups did not differ on any of these measures. Discussion focuses on possible explanations for the failure to find any differences in these measures and the future of personality assessment in mandibular pain dysfunction populations.

Covert positive reinforcement and pain modification: a test of efficacy and theory.

The effects of covert positive reinforcement, covert positive reinforcement plus positive expectancy, covert positive reinforcement plus negative expectancy, covert positive reinforcement of pain, attention placebo and no treatment on control of headache and finger pressure pain were examined. Self-report, behavioural and physiological measures were taken. Groups did not differ on any measures except for validity checks of the expectancy manipulation. The results provide little support for the efficacy of covert positive reinforcement in modifying pain. Additionally, the data failed to substantiate the theoretical basis of the procedure.

A more efficient biofeedback procedure for the treatment of nocturnal bruxism.

The study describes a noval approach in the use of a conditioning procedure for the treatment of nocturnal bruxism. The effectiveness of the procedure is demonstrated through its application with two nocturnal bruxists in controlled study designs. Subject 1 received several variations of this procedure and the result indicated that using a loud tone which she manually reset after awakening was the most effective approach to this treatment. The second study was designed to compare the effectiveness of relaxation training to the conditioning technique. Subject 2 failed to show any decrease in her bruxing behavior when taught relaxation. However, she showed immediate decreases in both frequency and duration of bruxing responses when treated with the biofeedback procedure. The need for future research in this area is discussed with emphasis on the development of low cost, home treatment units.

Modification of combined migraine-muscle contraction headaches using BVP and EMG feedback.

The effect of blood volume pulse (BVP) and frontalis muscle action potential (EMG) feedback on control of vasoconstriction of the temporal artery and frontalis muscle activity in combined migraine-muscle tension subjects was investigated in a multiple baseline design (across subjects and responses). The data indicated: (a) both subjects obtained an ability to control BVP during BVP feedback and EMG during EMG feedback; (b) there were decreases in frequency of migraine headaches during BVP feedback and decreases in muscle contraction headaches during EMG feedback. The results of this study supported the theoretical explanation of two pain mechanisms involved in combined muscle contraction-migraine headaches as well as the effectiveness of bio-feedback procedures that target directly the specific pain mechanism in the elimination of the two types of head pain.

Cephalic vasomotor feedback in the modification of migraine headache.

The effect of cephalic vasomotor response (CVMR) and frontalis electromyographic (EMG) feedback on control of temporal arterial vasoconstriction and frontalis muscle activity in migraine and muscle contraction headache patients was investigated. A single subject multiple baseline design (across subjects and responses) was introduced to evaluate (1) patterning in the two physiological systems and (2) the effects of CVMR and EMG feedback on headache activity. The data indicated that (a) all four patients demonstrated an ability to control CVMR activity during CVMR feedback and EMG during EMG feedback, (b) idiosyncratic patterns of physiological activity emerge during feedback training, and (c) learned control of the pain mechanism for muscle contraction and migraine headaches was related to reduced frequency and duration of these headaches.
