The disabling conditions of chronic low-back pain continue to cost patient, family, and society. The intricate mechanisms which perpetuate this medical condition often consist of both organic and functional factors. This study evaluated personality and psychosocial variables which may control individual responses to facet denervation, a treatment for chronic lumbar distress. The subjects were 47 chronic pain patients whose symptoms conformed to the facet syndrome. Patient responses to the Minnesota Multiphasic Personality Inventory (MMPI) and the Sixteen Personality Factor Questionnaire were reviewed in an effort to predict statistically symptomatic relief. Also, the patients' involvement in litigation and their accuracy in determining their pain level were studied as possible influencing variables. Results show the litigation factor and two scalesof the MMPI to be most useful in predicting patient response from facet denervation treatment.
