The Impact of Observational Learning on Physical Activity Appraisal and Exertion Following Experimental Back Injury and the Role of Pain-Related Fear

Description: Chronic low back pain (CLBP) is one of the most prevalent and disabling health conditions in the US and worldwide. Biomedical explanations of acute injury fail to account for why some individuals experience remission of pain and restoration of physical function while others do not. Pain-related fear, accompanied by elevated appraisals of physical exertion and avoidance of physical activity, has emerged as a central psychosocial risk factor for transition from acute injury to chronic pain and disability. Research has indicated that these pain-related factors may be maintained through observational learning mechanisms. To date, no studies have experimentally examined the role of observational learning and pain-related fear in the context of actual musculoskeletal injury. Accordingly, the present study examined the impact of observational learning and pain-related fear on activity appraisals and exertion following experimentally- induced acute low back injury. Healthy participants' appraisal of standardized movement tasks along with measures of physical exertion were collected prior to and following a procedure designed to induce delayed onset muscle soreness (DOMS) to the lower back. Following induction of DOMS, participants observed a video prime depicting CLBP patients exhibiting either high or low pain behavior during similar standardized movements. In line with hypothesized effects, participants assigned to the high pain behavior prime demonstrated greater elevation in pain and harm appraisals as well as greater decrement in physical exertion. Further in line with hypotheses, significant changes in appraisal and physical performance following the high pain behavior prime were only observed among participants endorsing high pain-related fear during baseline assessment. Discussion of findings addresses potential mechanisms of action as well as study limitations and direction for future research.

Quantitative EEG Analysis of Individuals with Chronic Pain

Description: Recent advances in neuroimaging and electromagnetic measurement technology have permitted the exploration of structural and functional brain alterations associated with chronic pain. A number of cortical and subcortical brain regions have been found to be involved in the experience of chronic pain (Baliki et al., 2008; Jensen et al., 2010). Evidence suggests that living with chronic pain shapes the brain from both an architectural and a functional perspective, and that individuals living with chronic pain display altered brainwave activity even at rest. Quantitative EEG (qEEG) is a method of spectral analysis that utilizes a fast Fourier transform algorithm to convert analog EEG signals into digital signals, allowing for precise quantification and analysis of signals both at single electrode locations and across the scalp as a whole. An important advance that has been permitted by qEEG analysis is the development of lifespan normative databases against which individual qEEGs can be compared (Kaiser, 2006; Thatcher et al, 2000). Pilot data utilizing qEEG to examine brainwave patterns of individuals with chronic pain have revealed altered EEG activity at rest compared to age- and gender-matched healthy individuals (Burroughs, 2011). The current investigation extended the findings of the pilot study by utilizing qEEG to examine a larger sample of individuals with chronic pain. Individuals with chronic pain displayed significantly reduced slow wave activity in frontal, central, and temporal regions. Findings will be presented in terms of specific patterns of altered EEG activity seen in individuals with chronic pain.

Treatment efficacy in a chronic pain population: Pre- to post-treatment.

Description: The purpose of the current study was to investigate the effects of a multidisciplinary pain management program on five measures of subjective psychosocial factors. Ninety-five participants in the comprehensive multidisciplinary treatment group and the standard medical intervention control group were surveyed about various psychosocial factors using Axis II of the West Haven - Yale Multidimensional Pain Inventory (MPI), pre- to post-treatment. It was hypothesized that post-treatment levels would be significantly lower than pre-treatment levels for all five psychosocial variables. Additionally, gender and ethnicity variables were examined. Based on preliminary analyses indicating pre-treatment differences between the experimental and control group, five 2 x 2 x 3 analyses of covariances (ANCOVAs) were used to examine the above hypotheses. Results indicated significant differences between the treatment conditions on measures of control, with the comprehensive group feeling more in control than the standard group at post-treatment. No other significant main effects for treatment condition were found on the measures of pain severity, interference with daily activities, negative mood, or social support. However, a significant gender main effect was found for social support at post-treatment, with females reporting more social support than males. A significant gender x ethnicity interaction was also found for post-treatment control, with African-American females exhibiting higher levels of control than the other groups. Finally, a significant gender x treatment condition was found for negative mood, with males in the comprehensive group reporting more affective distress than those in the standard group. In this study, control appeared to be an integral factor in the chronic pain sample and greatly improved with comprehensive multidisciplinary treatment; while other areas of relative efficacy were not confirmed in this population.

Quantitative EEG Analysis of Patients with Chronic Pain: An Exploratory Study

Description: This study examined quantitative EEGs of six individuals with chronic pain and compared them to an age- and gender-matched normative database of healthy control subjects in an attempt to discern whether a particular pattern of resting state EEG activity is associated with chronic pain. In the chronic pain group, significantly reduced absolute power was seen in delta and theta bandwidths at frontal sites in the eyes-closed condition. In the eyes-open condition, significantly reduced absolute power was seen in delta, theta, and alpha bandwidths at frontal, central, and temporal sites, and increased relative high beta power was seen in the parietal region. Reduced theta/high beta and delta/high beta ratios were seen in the parietal region. Quantitative EEG neuromarkers of chronic pain are suggested.

Sleep Patterns and Chronic Pain

Description: Sleep, emotions and pain are intimately connected, physiologically, by their location and utilization of the same brain centers and neurotransmitters. Sleep disturbances have been clinically observed in chronic pain populations; yet, no treatment program has formally addressed this aspect of patient care. It is hypothesized that a pain population (PN) will differ significantly from a non-injured workforce (WF) when reviewing quantitative and qualitative sleep data. This study strongly supports that sleep disturbances and socioeconomic decrements exist in chronic pain patients. Forty-seven variables were surveyed and 13 were found to show significant differences between the groups and seven were found to discriminate between the PN and WF groups at less than the .0001 level. A discriminant analysis was performed to determine the smallest model which could efficiently classify cases, according to successive root variables. The major discriminators are pain levels, medication, amount of sleep obtained and number of awakenings.

The Effects of Perceived Locus of Control and Dispositional Optimism on Chronic Pain Treatment Outcomes.

Description: The financial cost for health care and lost productivity due to chronic pain has been estimated at over $70 billion per year. Researchers have attempted to discover the psychosocial and personality factors that discriminate between people who learn to cope well with chronic pain and those who have difficulty adjusting. The purpose of the present study was to examine the effects of perceived locus of control and dispositional optimism on chronic pain treatment outcomes. Subjects reported significantly lower post-treatment pain levels as compared with pre-treatment levels (M = 0.66, SD = 1.58), t(45) = 2.85, p = .007 (two-tailed), but decreased pain was not associated with scores on the internality dimension of the Pain Locus of Control Scale (PLOC) or on the Life Orientation Test-Revised (LOT-R) (a measure of dispositional optimism). Overall, participants' increased coping ability was associated with scores on the LOT-R, but not with scores on the internality dimension of the PLOC. Subjects with the lowest pre-treatment scores on the LOT-R demonstrated significantly greater increases in post-treatment coping ability than those with the highest scores (F(2,40) = 3.93, p < .03). Participants with the highest pre-treatment scores on both the PLOC internality dimension and the LOT-R demonstrated greater post-treatment coping ability (F(2,32) = 4.65, p < .02), but not less post-treatment pain than other subjects. Participants' post-treatment LOT-R scores were significantly higher than their pre-treatment scores (M = 2.09, SD = 3.96), t(46) = 3.61, p = .001 (two-tailed), but post-treatment PLOC internality scores were not significantly higher than pre-treatment scores. Implications of these results are discussed.

The relationship between the MCMI-III and the MMPI-2 in a chronic pain population.

Description: The purpose of the present study was to study the relationship of MCMI-III clinical scales with MMPI-2 clusters in a chronic pain population. Data was obtained through assessment data (N = 242) from the Dallas Spinal Rehabilitation Center (DSRC), that included MMPI-2 and MCMI-III, as well as pre-and post-assessment information (n = 21) and follow-up questionnaires (n = 19). Subjects' age ranged from 18 to 64. Each patient had a primary diagnosis related to a back and/or a cervical injury, a chronic pain diagnosis, and often medical prescription dependency and/or addition. Each has experienced back pain in the lumbar region (L1 to L5) or cervical region (C1 to C7) for an average of 32 months. Patients with thoracic (mid-spine) and carpal tunnel pain were excluded from this study. A multivariate cluster analysis procedure was performed that yielded 3 homogeneous female MMPI-2 clusters and 4 MMPI-2 homogeneous male clusters. Seven multiple regression analyses were performed to determine which MCMI-III clinical scales predicted cluster membership in the MMPI-2 clusters. Results indicated that MCMI-III clinical scales "7" Compulsive, "X" Validity and "C" Borderline were predictors for membership in the male MMPI-2 clusters. Membership in the female MMPI-2 clusters were predicted by MCMI-III clinical scales "4" Histrionic, "T" Drug Dependence and "2A" Avoidant. Nineteen pre-and post-MCMI-IIIs were analyzed for change after participants completed the six-week pain management program. Paired-sample t-tests were performed on these data and revealed that significant change was noted on 10 MCMI-III clinical scales. Follow-up data questionnaires were available on these same individuals. Results from a correlation analysis indicated that patients who reported having supportive relationships with their spouse and family and a secure source of income report better quality of sleep, better mood, are able to relax and are believe that they are able to manage their pain. Participants who ...

The Use of Coping Strategies in Depressed and Nondepressed Chronic Pain Patients

Description: This study investigated the relationship between preferred coping strategies, and major stressors for nondepressed, and depressed chronic pain patients. The subjects for this study were 67 chronic pain patients who are participating in a pain/spinal rehabilitation program. The information collected from the individuals or their records included: (1) basic demographic information, (2) level of activity, (3) level of perceived pain, (4) medication usage, (5) therapist rating of level of stabilization, (6) scores on three inventories including the Coping Strategies Questionnaire, the Ways of Coping Checklist, and the Beck Depression Inventory. Analyses included an examination of the relationship between level of depression and (1) type of stressors, (2) coping strategies, and (3) level of perceived pain. Further analyses included multiple regression with outcome as defined by therapist ratings at the end of treatment, and patients' ratings at follow up as the criterion variables.

Does Unemployment Become a Major Stressor in the Evolution of Chronic Pain?

Description: Pain has been described as the most complex human experience and most frequent reason patients seek medical treatment. Few people fail to experience the pain associated with disease, injury, or medical/surgical procedures. However, the impact of unemployment that results from chronic pain suffering has not been widely researched. To present a comprehensive view of the effect unemployment has upon the chronic pain experience, this study focused upon stress philosophy, chronic pain, employment, and coping effectiveness. The Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and a Personal Data Questionnaire (PDQ) were administered to 96 persons (four groups of 24 subjects) representing either unemployed or employed and either chronic or non-chronic (acute) pain populations.

Correlates of the Scales of a Modified Screening Version of the Multidimensional Pain Inventory with Depression and Anxiety on a Chronic Pain Sample

Description: This correlational study investigated the relationship between changes in the psychosocial scales of the MPI Screener Patient Report Card (Clark, 1996) with changes in depression and anxiety with a sample of chronic pain patients who completed a 4-week outpatient interdisciplinary treatment program located in a large regional medical center. Race, gender, and primary pain diagnosis were additional predictors. Data analyzed came from an existing patient outcome database (N = 203). Five research assumptions were examined using ten separate (five pre and five post-treatment) hierarchical multiple regression analyses. Statistical significance was found in pre and post-treatment analyses with predictors BDI-II (Beck, Steer, & Brown, 1996) and BAI (Beck & Steer, 1993) on criterions Pain Interference, Emotional Distress, and Life Control, and Total Function.

The theory of planned behavior and adherence to a multidisciplinary treatment program for chronic pain.

Description: The primary objective of this study was to examine the association between the theory of planned behavior (TBP) and adherence to a multidisciplinary pain center (MPC) treatment program for chronic pain. While the results of several studies have provided support for the efficacy of MPC treatment in chronic pain, the problems of adherence and attrition are important. TPB is a cognitive/social model of behavior that has been used to predict a variety of behaviors, although it has never been used to predict adherence to a multidisciplinary chronic pain treatment program. It was predicted that Adherence would be predicted by Intentions and that Intentions would be predicted by 1) Perceived Social Norms, 2) Perceived Behavioral Control, 3) Attitudes Toward New Behavior (completing the treatment program), and 4) Attitude Toward Current Behavior (maintaining current treatment and coping strategies). It was found that the total Intentions scores did not predict the total Adherence scores. However, Intentions was predicted by 1) Perceived Behavioral Control, 2) Attitudes Toward New Behavior (completing the treatment program), and 3) Attitude Toward Current Behavior (maintaining current treatment and coping strategies). The finding that Perceived Social Norms did not predict Intentions was consistent with results of previous studies with the TBP. The secondary objective was to examine the extent to which MPC treatment affects patients' attitudes towards behaviors that are associated with successful pain management. The majority of the patients (82%) developed a more favorable attitude toward the program and their average report of the importance of the program was 6.78 on a 10-point scale. The majority of patients (74%) reported experiencing a greater decrease in pain than expected, and the average amount of pain decrease was 5.39 on a 10-point scale.

Imagery Technology: Effects on a Chronic Pain Population

Description: The effects of a computer program (Health Imagery Technology Systems, HITS) designed to promote attitude and cognitive changes through elicitation of evoked response potentials were evaluated with chronic pain patients. A treatment and control group were used for comparison (52 patients, 22 females, 32 males, mean ages 47). Wechsler Adult Intelligence Scale-Revised subtests, a Semantic Differential scale, the Health Attribution Test, an imagery protocol, the McCoy-Lawlis Pain Drawing, and the Zung Depression scale were used at admission and discharge to measure change. A pre- post-mood thermometer was used with the treatment group. The hypotheses that the treatment group would show significant changes on these measures were tested with a two group repeated measures analysis of variance design. No significant changes were noted for either group on the intellectual measures, on health attitudes, or reports of pain. The similarities subscale showed significant within group variance (F = 5.46, p < .023). One bipolar adjective pair indicated significant differences (F = 4.79, p < .035), possibly a result of chance. One of seven imagery measures suggested a significant improvement in strength of imagery for the treatment group (F = 18.2, p < .00008). Both groups showed significantly improved imagery of body defenses (F = 4.58, £ < .037) and significantly reduced depression scores (F = 15.93, p < .000021). A mood thermometer was measured for the treatment group alone and five situational mood changes were significant in predicted directions. Post hoc discriminant analysis showed significant differences only on one adjective pair (F = 9.75, p < .0029). No combination of variables added to the prediction of group membership. Overall, the effects of the HITS program did not seem strong enough to indicate its value as a treatment modality in chronic pain populations beyond current treatment. It did indicate some significant situational mood ...

Muscle Tension and Locus Of Pain in Subjects With and Without Chronic Backpain

Description: 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.

Heart rhythm variability in persons with chronic pain.

Description: The present study evaluated the utility of heart rhythm coherence (HRC) feedback to reduce the reported pain intensity of patients enrolled in a multimodal pain management program. Participants were recruited and assigned to a usual treatment group (UT) or a heart rhythm coherence feedback group (UT+HRC). It was hypothesized that UT+HRC participants who achieved heart rhythm coherence would report a reduction of pain intensity, as measured by the McGill Pain Inventory. For those whose pain intensity decreased, it was also expected that their self reported levels of depression as measured by the Beck Depression Inventory-Second Edition and state anger as measured by the State Trait Anger Inventory would decrease. It is also hypothesized that with a reduction in pain levels, anger, and depression, blood pressure would also decrease among those who had high blood pressure prior to the intervention. Multivariate analyses of variance (MANOVA) were used to investigate the relationship between treatment condition, coherence status and pain levels. A series of independent t-tests were utilized to investigate the change in pain, depression, and state anger from baseline to posttest, followed by Pearson product moment correlation coefficients on difference scores to understand the relationship between the outcome variables for Hypothesis 2. Standard multiple regression analyses were computed using difference scores to determine if the outcome measures were significant predictors of systolic blood pressure and diastolic blood pressure. Results indicated a failure to reject the null with regard to hypothesis one. No relationship between treatment assignment, coherence status or pain levels were found. Hypothesis 2 was partially supported. Although there was a positive significant relationship between depression and anger when utilizing difference scores, these affective measures were not related to difference scores on either pain measure. In regard to Hypothesis 3, there was also a failure to reject the null. None of ...

Factor Analysis of Health Concerns in the Chronic Back Pain Patient-MMPI2

Description: The purpose of this study was to analyze the factor structure of items pertaining to health on the Minnesota Multiphasic Personality Inventory (MMPI2) for chronic back pain patients in comparison to a control group. The results may be used as groundwork for developing an MMPI2 subscale to describe this population. The groups differed in the sequence of the resulting factors and the percentage of variance accounted for by each factor. The factors extracted when evaluating the control group were titled in order: Poor Physical Health, Digestive Difficulties, Equilibrium, Depression/Malaise, and Multiple Somatic Complaints. Resulting factors for the pain group were: Depression/Malaise, Digestive Difficulties, Multiple Somatic Complaints, Headaches/Dizziness, and Neurological Reaction/Poor Physical Health.

Massage Therapy: Mind/Body Effects on Chronic Pain Patients

Description: This study assessed the influence of massage therapy on the psychobiology of chronic pain patients. A pre- and posttest design measured the effects of a one-month treatment program Twenty outpatients and twenty inpatients of two chronic pain treatment programs, were administered several psychological and physiological tests before and after the study. Experimental subjects received massage therapy twice a week for one month in addition to their other therapies. Control subjects continued with their regular treatment modalities for one month. Results showed statistically significant differences (p < .05) on 5 of the 17 psychological variables and on the electromyograph levels. Analysis of Holmes-Rahe scores suggested that these differences were not attributable to the artifact effect of differential life stress.

A Culturally Sensitive Intervention in Pain Management Settings: Use of Dichos in Multi-Ethnic Pain Groups.

Description: The present study explored whether use of Spanish language sayings, or dichos, improved group climate within multi-ethnic chronic pain groups. Use of this form of figurative language fits within psychological theory identifying use of metaphor as a means of promoting change and creating new meaning. Further, metaphor use is consistent with the broader aims of experiential therapy. Group climate was measured by group members' self reports using the Group Climate Questionnaire-Short Form. A pilot study involving Latino Americans in medical and non-medical contexts aided in categorizing dichos as high versus low-relevance. It was anticipated that clients would rate high-relevance sessions as involving greater engagement, and less conflict and avoidance than low-relevance groups. Participants were recruited from four multidisciplinary pain management clinics offering similar programs. Once every four to six weeks, group leaders were provided with a list of either high or low-relevance dichos, and were blind to the existence of dichos categories. Three hierarchical regression analyses were employed to determine whether dichos relevance, characterized as low, mixed or highly relevant, contributed to variance in group conflict, avoidance and engagement. Dichos familiarity was the last variable entered into the regression equation, with gender, ethnicity and acculturation score entered in sequential fashion. Consistent with predictions, low-relevance groups yielded higher conflict scores than all groups combined. Also, high-relevance groups predicted lower avoidance when compared to all groups. In contrast to hypotheses, high-relevance groups predicted lower ratings of group engagement when compared to all groups. Post-hoc analysis indicated the mixed-relevance groups yielded significantly higher engagement scores than the low and high-relevance groups. Implications of these findings are discussed in relation to impact on approaches to group therapy with Latino American clients, and within the chronic pain population. Limitations of the study and recommendations for future research are offered.

Cluster Analysis of the MMPI-2 in a Chronic Low-Back Pain Population

Description: The Minnesota Multiphasic Personality Inventory (MMPI) is the most frequently used psychological measure in the assessment of chronic pain. Since the introduction of the MMPI-2 in 1989 only two published studies have focused on cluster analysis of chronic pain patients. This study investigated MMPI-2 cluster solutions of chronic low-back pain patients. Data was collected from 2,051 chronic low-back pain patients from a multidisciplinary pain clinic in the southwestern United States. A hierarchical clustering procedure was performed on K-corrected T-scores of the MMPI-2 using the three validity and ten clinical scales. Four relatively homogeneous subgroups were identified for each sex with the MMPI-2. In general, these results replicated the findings of previous researchers using both the MMPI and MMPI-2.

Validation of the Spanish Dallas Pain Questionnaire

Description: The purpose of this study was to validate the Spanish version of the Dallas Pain Questionnaire (DPQ). Not only does the DPQ offer the potential of statistical and clinical diagnostic value but also is easily interpretable across cultural lines. No such instrument has presently been validated for the Mexican-American population. A total of 81 Spanish speaking subjects participated in this study. Of these subjects, 56 were classified as chronic pain patients by nature of their medical diagnosis and duration of pain. The 25 normal subjects were family members of the chronic pain patients and members of the Northern New Mexico Hispanic community chosen at random. Hypothesis one predicted that reliability would be obtained on Spanish speaking populations based on test-retest with correlation coefficients of the items. The second hypothesis predicted that the Spanish DPQ would have content validity or consistent internal structure on those items that measure the trait or behavior of interest based upon factor analysis approaches and internal consistency measures. Hypothesis three predicted that the Spanish version of the DPQ would significantly correlate with the English version of the DPQ on all four factors. All four hypotheses were supported. The Spanish DPQ showed reliability over time based on test-retest. The statistics revealed an internally reliable test, alpha coefficient analysis and factor analysis. The validity was supported by significant correlations with the English DPQ and discrimination between chronic and nonchronic pain patients. While all four hypotheses were upheld, interpretation of the present findings should be moderated by recognition of the limitations of the studies. Future studies should test larger samples to improve confidence in the psychometric properties of the instrument. Still notable limitations of the questionnaire are that the Spanish DPQ is a form that is more accurately viewed as a global measure.

Cognitive Decline in Chronic Pain Patients: A Neuropsychological Evaluation

Description: The purpose of the present study was to investigate cognitive functioning in a group of 30 chronic pain patients (CPG) as compared to a group of 39 acute pain patients (APG). In order to assess cognitive performance, certain subtests were selected from the McCarron-Dial System (MDS) of Neuropsychological Evaluation. Specifically, a measure of haptic discrimination was used along with the Bender Visual Motor Gestalt Test. As such, completion of these subtests required a cortically mediated, central nervous system processing of sensory information. This particular method of assessment was chosen because it provided a nonverbal measure of higher-order cognitive performance. Additionally, the haptic measure provided separate scores for right and left hemispheric functioning. Data analysis revealed significantly poorer Bender performance among CPG members (t(69) = -5.09, E - •0004, two tailed). Further data analysis revealed that the CPG performed significantly poorer on certain of the haptic discrimination subtests. Specifically, both texture and configuration scores for the right hemisphere were significantly lower among CPG members (texture, p = -042 and configuration, p = .002). Subsequent analyses were conducted to determine predictive relationships between important variables. These data are discussed in terms of their clinical significance and importance for future research.

Correlational Study of the UNT Neuropsych-Screen, the MMPI and Time among Chronic Pain Patients

Description: Although many theorists have speculated that chronic pain may be linked to some sort of central neuropsychological integration deficit, a review of the current literature reveals no empirical support for this theory. This study attempts to assess the severity, if any, of neuropsychological deficits in chronic pain subjects by using a neuropsychological screen developed at the University of North Texas. Also, presented are studies of correlations between the UNT Neuropsych-screen and the MMPI. the Dallas Pain Questionnaire (DPQ), the Dallas Pain Drawing CDPD), and time since injury in order to assess any possible relationships. The subjects in this study consist of 100 volunteers. Of these subjects, 74 were patients of the Spinal and Chronic Pain Center at Medical Arts Hospital in Dallas, Texas and represented the clinical population. The remaining 26 subjects were staff volunteers from the hospital . The results of the study indicate significant differences between chronic pain subjects and non-pain subjects across many areas of neuropsychological functioning, as well as other significant correlations among many of the variables. The implications of this study are elaborated upon, in the discussion section, in detail along with limitations and future research directions.
