While the actual overt, covert, and neurophysiological responses necessary for changes in subjective pain
levels can vary (Arena & Blanchard, 2002), the fundamental paradigm in biofeedback involves contingent reinforcement of certain neurophysiologically based responses, such as muscle tension or blood flow, and overt verbal responses with positive feedback.
The purpose of this study is to evaluate the factors that affect patients' subjective pain
5 g collagen and other matrix components, including glucosamine daily for four months, resulted in a marked alleviation of subjective pain
assessed by the face scale.
But regardless of the validity of the above evolutionary hypothesis, if the current finding that pain increases impulsiveness has generalization, then individuals living with physical pain, or even purely subjective pain
, are at increased risk for making impulsive choices, such as drug abuse, binge eating, or work absenteeism; and that while producing immediate reinforcement, these choices may ultimately result in greater pain.
Patients were evaluated using a VAS, objective and subjective pain
evaluations and physical exams.
