    Acceptance of Pain in Neurological Disorders: Associations With Functioning and Psychosocial Well-Being
    (American Psychological Association, 2013) Kratz, Anna L.; Hirsh, Adam T.; Ehde, Dawn M.; Jensen, Mark P.; Psychology, School of Science
    Objective: Chronic pain acceptance has been shown to be related to positive adjustment to chronic pain in patients presenting with pain as a primary problem. However, the role of pain acceptance in adjustment to chronic pain secondary to a neurological disorder that is often associated with physical disability has not been determined. The purpose of this study was to examine whether two domains of chronic pain acceptance--activity engagement and pain willingness--predict adjustment to pain, controlling for pain intensity and key demographic and clinical variables in individuals with muscular dystrophy (MD), multiple sclerosis (MS), post-polio syndrome (PPS), or spinal cord injury (SCI). Method: Participants were 508 community-dwelling adults with a diagnosis of MD, MS, PPS, or SCI who also endorsed a chronic pain problem. Participants completed self-report measures of pain acceptance, quality of life, pain interference, pain intensity, depression, and social role satisfaction. Results: Hierarchical linear regressions indicated that activity engagement predicted lower pain interference and depression, and greater quality of life and social role satisfaction. Pain willingness predicted less pain interference and depression. Together, the two pain acceptance subscales accounted for more variance in outcomes than did self-reported pain intensity. Conclusions: Findings correspond with the broader pain acceptance literature, although activity engagement appears to be a more robust predictor of adjustment than does pain willingness. This research supports the need for future studies to determine the extent to which treatments that increase acceptance result in positive outcomes in persons with chronic pain secondary to neurological disorders.

    Combining Cognitive Behavioral Therapy and Milnacipran for Fibromyalgia: A Feasibility Randomized-controlled Trial
    (Wolters Kluwer, 2013) Ang, Dennis C.; Jensen, Mark P.; Steiner, Jennifer L.; Hilligoss, Janna; Gracely, Richard H.; Saha, Chandan; Psychology, School of Science
    Objectives: To evaluate the feasibility of a randomized-controlled trial and to obtain estimates of the effects of combined cognitive-behavioral therapy (CBT) and milnacipran for the treatment of fibromyalgia. Methods: Fifty-eight patients with fibromyalgia were randomized to 1 of the 3 treatment arms: (1) combination therapy (n = 20); (2) milnacipran+education (n = 19); and (3) placebo+CBT (n = 19). Patients received either milnacipran (100 mg/d) or placebo. Patients also received 8 sessions of phone-delivered CBT or educational instructions, but only from baseline to week 9. Assessments were conducted at baseline, week 9, and 21. The primary endpoints were baseline to week 21 changes in weekly average pain intensity and physical function (SF-36 physical function scale). Results: Compared with milnacipran, combination therapy demonstrated a moderate effect on improving SF-36 physical function (SE = 9.42 [5.48], P = 0.09, effect size = 0.60) and in reducing weekly average pain intensity (mean difference [SE] = -1.18 [0.62], P = 0.07, effect size = 0.67). Compared with milnacipran, CBT had a moderate to large effect in improving SF-36 physical function (mean difference [SE] = 11.0 [5.66], P = 0.06, effect size = 0.70). Despite the presence of concomitant centrally acting therapies, dropout rate was lower than anticipated (15% at week 21). Importantly, at least 6 out of the 8 phone-based therapy sessions were successfully completed by 89% of the patients; and adherence to the treatment protocols was > 95%. Conclusions: In this pilot study, a therapeutic approach that combines phone-based CBT and milnacipran was feasible and acceptable. Moreover, the preliminary data supports conducting a fully powered randomized-controlled trial.

    Moderate-vigorous physical activity improves long-term clinical outcomes without worsening pain in fibromyalgia
    (Wiley, 2013) Kaleth, Anthony S.; Saha, Chandan K.; Jensen, Mark P.; Slaven, James E.; Ang, Dennis C.; Exercise & Kinesiology, School of Health and Human Sciences
    Objective: To evaluate the relationship between long-term maintenance of moderate to vigorous physical activity (MVPA) and clinical outcomes in fibromyalgia (FM). Methods: Patients with FM (n = 170) received individualized exercise prescriptions and completed baseline and followup physical activity assessments using the Community Health Activities Model Program for Seniors questionnaire at weeks 12, 24, and 36. The primary outcome was the change in the Fibromyalgia Impact Questionnaire-Physical Impairment (FIQ-PI) score. The secondary outcomes included improvements in overall well-being (FIQ total score), pain severity ratings, and depression. Results: Using a threshold increase in MVPA of ≥10 metabolic equivalent hours/week above usual activities, 27 subjects (15.9%) increased and sustained (SUS-PA), 68 (40%) increased but then declined (UNSUS-PA), and 75 (44.1%) did not achieve (LO-PA) this benchmark. Compared to LO-PA subjects, both SUS-PA and UNSUS-PA subjects reported greater improvement in FIQ-PI (P < 0.01) and FIQ total score (P < 0.05). Additionally, the SUS-PA group reported greater improvement in pain severity compared to the LO-PA group (P < 0.05). However, there were no significant group differences between SUS-PA and UNSUS-PA for any primary or secondary outcome measure. Conclusion: Increased participation in MVPA for at least 12 weeks improved physical function and overall well-being in patients with FM. Although sustained physical activity was not associated with greater clinical benefit compared with unsustained physical activity, these findings also suggest that performing greater volumes of physical activity is not associated with worsening pain in FM. Future research is needed to determine the relationship between sustained MVPA participation and subsequent improvement in patient outcomes.

    Pain Coping Skills Training for Patients Who Catastrophize About Pain Prior to Knee Arthroplasty: A Multisite Randomized Clinical Trial
    (Journal of Bone and Joint Surgery, Inc., 2019-02-06) Riddle, Daniel L.; Keefe, Francis J.; Ang, Dennis C.; Slover, James; Jensen, Mark P.; Bair, Matthew J.; Kroenke, Kurt; Perera, Robert A.; Reed, Shelby D.; McKee, Daphne; Dumenci, Levent; Medicine, School of Medicine
    BACKGROUND: Pain catastrophizing has been identified as a prognostic indicator of poor outcome following knee arthroplasty. Interventions to address pain catastrophizing, to our knowledge, have not been tested in patients undergoing knee arthroplasty. The purpose of this study was to determine whether pain coping skills training in persons with moderate to high pain catastrophizing undergoing knee arthroplasty improves outcomes 12 months postoperatively compared with usual care or arthritis education. METHODS: A multicenter, 3-arm, single-blinded, randomized comparative effectiveness trial was performed involving 5 university-based medical centers in the United States. There were 402 randomized participants. The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Scale, measured at baseline, 2 months, 6 months, and 12 months following the surgical procedure. RESULTS: Participants were recruited from January 2013 to June 2016. In 402 participants, 66% were women and the mean age of the participants (and standard deviation) was 63.2 ± 8.0 years. Three hundred and forty-six participants (90% of those who underwent a surgical procedure) completed a 12-month follow-up. All 3 treatment groups had large improvements in 12-month WOMAC pain scores with no significant differences (p > 0.05) among the 3 treatment arms. No differences were found between WOMAC pain scores at 12 months for the pain coping skills and arthritis education groups (adjusted mean difference, 0.3 [95% confidence interval (CI), -0.9 to 1.5]) or between the pain coping and usual-care groups (adjusted mean difference, 0.4 [95% CI, -0.7 to 1.5]). Secondary outcomes also showed no significant differences (p > 0.05) among the 3 groups. CONCLUSIONS: Among adults with pain catastrophizing undergoing knee arthroplasty, cognitive behaviorally based pain coping skills training did not confer pain or functional benefit beyond the large improvements achieved with usual surgical and postoperative care. Future research should develop interventions for the approximately 20% of patients undergoing knee arthroplasty who experience persistent function-limiting pain. LEVEL OF EVIDENCE: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

    Research to Encourage Exercise for Fibromyalgia (REEF): Use of Motivational Interviewing, Outcomes From a Randomized-controlled Trial
    (The Clinical Journal of Pain, 2013) Ang, Dennis C.; Kaleth, Anthony S.; Bigatti, Silvia; Mazzuca, Steven A.; Jensen, Mark P.; Hilligoss, Janna; Slaven, James; Saha, Chandan
    Objectives Regular exercise is associated with important benefits in patients with fibromyalgia (FM). Unfortunately, long-term maintenance of exercise after a structured program is rare. The present study tested the efficacy of Motivational Interviewing (MI) to promote exercise and improve symptoms in patients with FM. Methods 216 patients with FM were randomized to 6 MI sessions (n=107) or an equal number of FM self-management lessons (education control/EC, n=109). Co-primary endpoints were an increase of 30 minutes in moderate-vigorous physical activity and improvement in the Fibromyalgia Impact Questionnaire-Physical Impairment (FIQ-PI) score, assessed at pre-treatment, post-treatment, and 3- and 6-month follow-up. Secondary outcomes included clinically meaningful improvements in FIQ score, pain severity ratings, and a 6-minute walk test. Results There were no significant treatment group differences in either co-primary endpoint at 6-month follow-up. However, more MI participants than controls exhibited meaningful improvements in FIQ score at 6-month follow-up (62.9% vs. 49.5%, p=0.06). Compared to EC subjects, MI subjects also displayed a larger increment in their 6-minute walk test (43.9 vs. 24.8 meters, p=0.03). Additionally, MI was superior to EC in increasing the number of hours of physical activity immediately post-intervention and in reducing pain severity both immediately after the intervention and at 3-month follow-up. Conclusions Despite a lack of benefits on long term outcome, MI appears to have short-term benefits with respect to self-report physical activity and clinical outcomes. This is the first study in FM that explicitly addresses exercise maintenance as a primary aim.
