Internal health locus of control as a predictor of pain reduction in multidisciplinary inpatient treatment for chronic pain: a retrospective study

Interoceptive bodily awareness in patients seeking pain relief with osteopathic manipulative treatment: an observational cohort pilot study

CONTEXT

Interoceptive bodily awareness (IBA) is one's attentional focus on and relationship with comfortable and uncomfortable (e.g., pain) internal body sensations. Integrating IBA into research on osteopathic manipulative treatment (OMT) is growing, both as an outcome and predictor of treatment outcomes; however, it has yet to be studied in a clinical setting.

OBJECTIVES

We aimed to conduct a pilot study to measure IBA, with the Multidimensional Assessment of Interoceptive Awareness (MAIA), in patients seeking OMT for pain, and to test if OMT exposure may be associated with higher IBA as measured by the MAIA. The primary outcome was the change in MAIA scores, and the secondary outcomes were reduction in pain intensity, reduction in pain interference, and increase in participants' perception of change post-OMT.

METHODS

A convenience sample was recruited from individuals presenting for OMT appointments at a College of Osteopathic Medicine OMT teaching clinic. Participants were recruited into our single-arm observational cohort study (n=36), and categorized into one of two groups, OMT-naïve (n=19) or OMT-experienced (n=17), based on prior exposure to OMT. We measured MAIA scores and clinical pain-related outcomes prior to, immediately after, and at 1 and 3 weeks after a usual-care OMT session in the clinic. Covariates including experience with mind-body activities, non-OMT body work, and physical and emotional trauma were also collected to explore potential relationships. We utilized t tests to compare MAIA scores and pain outcomes between groups and across time points. Stepwise regression models were utilized to explore potential relationships with covariates.

RESULTS

The OMT-experienced group scored higher on the MAIA scales "Not-worrying" (p=0.002) and "Trusting" (p=0.028) at baseline. There were no significant changes in the MAIA scores before and after the single OMT session. Analysis of secondary outcomes revealed that all pain outcomes significantly decreased post-OMT (p<0.05), with the largest relative improvements in the acute pain and OMT-naïve subgroups, with diminishing effects over time.

CONCLUSIONS

Assessing IBA with MAIA in a clinical OMT setting is feasible. There were significant positive correlations between OMT exposure and two of the eight MAIA scales. Future studies are justified to further explore this relationship.

How Treatment Motivation Predicts Favorable Outcomes in Interdisciplinary Multimodal Pain Treatment Among Patients with Chronic Primary Pain

As motivation for psychological treatment at intake has been shown to predict favorable outcomes after an inpatient stay, this study aimed to further characterize the different components of psychological treatment motivation that predict favorable treatment outcomes. 294 inpatients with chronic primary pain participating in an interdisciplinary multimodal pain treatment in a tertiary psychosomatic university clinic completed a battery of psychological questionnaires at intake and discharge. Treatment motivation was assessed at intake using the scales of the FPTM-23 questionnaire, while pain intensity, pain interference, anxiety, and depression were assessed both at intake and discharge. After treatment, pain intensity, pain interference, anxiety, and depression were significantly reduced. While higher levels on the FPTM-23 scale of suffering predicted smaller decreases in anxiety after treatment, higher scores on the scale of hope, i.e., lower levels of hopelessness, predicted lower levels of pain interference, anxiety, and depression after treatment. None of the scales of treatment motivation predicted pain intensity levels after treatment. Above and beyond providing symptom relief, reducing hopelessness and fostering hope regarding the treatment process and outcome might help clinicians treat patients with chronic primary pain more effectively.

Impact of Locus of Control on Patient-Provider Communication: A Systematic Review

Growing evidence shows there is heterogeneity in patient communication preferences and a need to tailor communication approaches accordingly. However, little is known about the psychosocial factors that influence communication preferences. Among them is locus of control (LOC), a belief about who or what determines outcomes, including health. Although LOC theory was developed over 60 years ago as a personality theory, its relevance in healthcare has increased over the past two decades. There is a paucity of empirical evidence on patient or provider LOC as it influences communication quality and outcomes in healthcare settings. We conducted a systematic review to collate the current state of the literature.We carried out a comprehensive search of PubMed MEDLINE, Embase, PsycInfo, and Cochrane Library databases to retrieve relevant peer-reviewed articles. A total of 1152 publications were identified. Our final review included 17 articles that underwent data extraction and quality assessment.The included studies found evidence of LOC associations with several patient and provider communication-related outcomes including satisfaction with care; medical decision-making and communication preferences; adherence; and patient-provider rapport. As opposed to generalized approaches to communication, assessing patient LOC may allow clinicians to tailor their approaches to match patients' LOC. Our findings provide a starting point and highlight the need for future studies.

Negative impact of chronic pain: The role of locus of control and perceived family validation of chronic pain

The present study investigates how participants' locus of control and their family and friends' validation of their pain influences participants' chronic pain experiences. Four thousand, 25 adults were recruited through the Chronic Pain In America survey. Results show that individuals who endorse an internal locus of control and experience family and friends' validation of their chronic pain reported better chronic pain outcomes and less negative life impact due to chronic pain. The current results indicate the locus of control and family and friends' validation of chronic pain experience plays an important role in chronic pain and the impact of chronic pain across the life course.

Psychological variables and quality of life in women with endometriosis

BACKGROUND

Endometriosis is a common gynecological condition which has been found to have a detrimental impact upon women's quality of life (QoL). This study investigated the impact of pain self-efficacy, health locus of control (HLOC), coping style and illness uncertainty on QoL in women with endometriosis.

METHOD

Two hundred and thirty women completed online questionnaires. Standard multiple regressions assessed the relationship between the psychological predictors and QoL.

RESULTS

The psychological variables accounted for a statistically significant proportion of the variance (p < .0005) in scores across the four QoL domains. The model accounted for 55, 26, 10 and 32% of the scores in physical, psychological, social and environmental QoL domains, respectively. Pain self-efficacy made the largest unique contribution, followed by illness uncertainty.

CONCLUSIONS

Women's perception of their ability to manage their pain and how uncertain they felt about their condition, were important factors in QoL, particularly in the physical domain.

The Influence of the Locus of Control Construct on the Efficacy of Physiotherapy Treatments in Patients with Chronic Pain: A Systematic Review

The biopsychosocial paradigm contemplates the patient’s personality traits in physiotherapy treatments for chronic pain. Among these traits, the locus of control has a direct relationship with the person’s coping strategies in the face of their health problems. The objective of this systematic review was to assess the influence of locus of control on the efficacy of physiotherapy treatments in patients with chronic pain. A systematic review of the publications of the last ten years in Pubmed, Scopus, Science Direct and Web of Science databases was conducting with the terms physical therapy modalities, chronic pain, internal-external control, self-management, physical therapy and physiotherapy. The inclusion criteria were participants with chronic pain lasting at least three months who have received at least one session of physical therapy; the studies should have collected the patient’s locus of control as a prognostic factor at the beginning of physiotherapy treatment; the variables studied should include the pain intensity or clinical variables related to pain. A total of 13 articles were found, of which three were experimental studies and ten were observational studies. The included samples had chronic knee pain, nonspecific back pain, low back pain or neck pain; were people over 65 years of age or patients who had undergone hand surgery. In patients with chronic pain for more than three months, the locus of control construct participates as a predictor of the results of physiotherapy treatment. The presence of an internal locus of control favors better results. The personality traits of the subjects represent an important factor to take into account when planning physiotherapy treatments.

Physiotherapy support for self-management of persisting musculoskeletal pain disorders

BACKGROUND

Musculoskeletal pain (MSKP) is an extremely common pain disorder in almost all populations. Self-management (SM) support is a programme to prepare people to self-manage their health condition effectively, while maintaining quality of life. SM is a cost-effective and context-specific strategy to address the global public health burden.

OBJECTIVES

Self-management needs a change in behaviour from seeking unnecessary medical care to safely self-managing symptoms. As changing individuals' behaviour is challenging, the objective of my literature review was to identify the characteristics, in both therapist and patient, to successfully engage in SM.

METHOD

A narrative literature review, that could inform evidence-based support programmes for SM of MSKP.

RESULTS

Studies on successful implementation of SM of MSKP do not report strong outcomes. However, in more recent years a few positive outcomes were reported, possibly as a result of research evidence for the application of psychosocial skills and contemporary pain neuroscience in the management of persistent MSKP.

CONCLUSION

Psychologically-informed physiotherapy, addressing psychosocial barriers to the maintenance of SM programmes, could facilitate more successful outcomes.

CLINICAL IMPLICATIONS

Before engaging in a SM support programme, obstacles to behaviour change must be identified and addressed in a SM support programme, to facilitate individuals towards taking safe responsibility for their healthcare. Therapists working with patients with persistent MSKP, should upskill themselves to be in line with the latest pain and psychosocial research literature. Moreover, communication skills training seems to be a priority for effective SM support programmes.

Does aerobic exercise training alter responses to opioid analgesics in individuals with chronic low back pain? A randomized controlled trial

ABSTRACT

We tested whether aerobic exercise training altered morphine analgesic responses or reduced morphine dosages necessary for adequate analgesia. Patients with chronic back pain were randomized to an 18-session aerobic exercise intervention (n = 38) or usual activity control (n = 45). Before and after the intervention, participants underwent 3 laboratory sessions (double-blinded, crossover) to assess effects of saline placebo, i.v. morphine (0.09 mg/kg), and i.v. naloxone (12 mg) on low back pain and evoked heat pain responses. Differences in evoked and back pain measures between the placebo and morphine conditions indexed morphine analgesia, with pre-post intervention changes the primary outcome. Endogenous opioid analgesia was indexed by differences in evoked and low back pain measures between the naloxone and placebo conditions. A Sex X Intervention interaction on the analgesic effects of morphine on visual analogue scale back pain intensity was observed (P = 0.046), with a similar trend for evoked pain threshold (P = 0.093). Male exercisers showed reduced morphine analgesia pre-post intervention, whereas male controls showed increased analgesia (with no differences in females). Of clinical significance were findings that relative to the control group, aerobic exercise produced analgesia more similar to that observed after receiving ≈7 mg morphine preintervention (P < 0.045). Greater pre-post intervention increases in endogenous opioid function (from any source) were significantly associated with larger pre-post intervention decreases in morphine analgesia (P < 0.046). The overall pattern of findings suggests that regular aerobic exercise has limited direct effects on morphine responsiveness, reducing morphine analgesia in males only.

What Influences Outcomes From Inpatient Multidisciplinary Pain Management Programs?: A Systematic Review and Meta-analysis

OBJECTIVES

Although inpatient multidisciplinary pain management programs (PMPs) are effective for chronic pain, not all patients benefit equally and there is limited evidence regarding predictors of outcome. This meta-analysis aimed to identify patient or program characteristics associated with outcomes from inpatient PMPs, and to examine the time course of effects following discharge.

MATERIALS AND METHODS

Medline, EBSCO, and Scopus were searched to identify articles reporting outcomes from inpatient multidisciplinary PMPs. Information was extracted on study design, participant and program characteristics, and outcomes. Effect sizes were computed for pain, physical function, depression, anxiety, and mental health outcomes. Study-level predictors of outcome were investigated with moderator analyses and meta-regression. A risk of bias assessment and sensitivity analyses were conducted and the GRADE criteria for prognostic studies were applied to assess confidence in findings.

RESULTS

In all, 85 studies (111 cohorts; 15,255 participants) were included. Three quarters of studies demonstrated low risk of bias. Larger effect sizes (for at least 1 outcome measure) occurred in studies where participants had more severe pain (greater intensity/longer duration), participants with alcohol or drug problems were not excluded, samples comprised mixed pain conditions, and programs included a cognitive component and/or a passive therapy component. Effect sizes for pain and physical function were maintained at follow-up, but effect sizes for depression and anxiety declined over time.

DISCUSSION

Inpatient multidisciplinary PMPs may be well suited to patients with severe or long-lasting pain. Programs should adopt broad patient inclusion criteria, and outcomes were similar for programs based on cognitive-behavioral versus mindfulness/acceptance-based therapies.
