The Mediating Role of Depression and Negative Partner Responses in Chronic Low Back Pain and Relationship Satisfaction

Is Social Support Associated With Clinical Outcomes in Adults With Nonspecific Chronic Low Back Pain? A Systematic Review

OBJECTIVES

Nonspecific chronic low back pain (NSCLBP) is associated with psychological and social factors such as social support. However, little research has focused on the latter. This article aimed to review the literature on the association between social support and clinical outcomes of patients with NSCLBP, particularly regarding differences in sex, gender, and types of social support.

METHODS

MEDLINE, EMBASE, Web of Science, PsycINFO, and CENTRAL were searched until April 19, 2024, without restrictions of time or language. Eligible articles were observational studies reporting measures of association between social support and clinical outcomes among adults with NSCLBP. Risk of bias was assessed using the QUIPS tool, and findings were analyzed qualitatively. This systematic review was registered on PROSPERO (CRD42022363210).

RESULTS

Of the 3528 identified studies, 11 were included in the review (1290 patients), showing a moderate to high risk of bias. Of the 5 studies showing a significant finding for pain, 4 reported a negative correlation (r=-0.18, -0.32, -0.35, -0.36) and 1 did not report any association index. Of the 6 studies showing a significant finding for disability, 2 reported a negative correlation (r=-0.29, -0.42), 2 reported a positive association (r=0.322; β=0.29), and 2 did not report any association index. No data was available for the investigated subgroups or secondary clinical outcomes.

DISCUSSION

Small associations were found between social support and clinical outcomes of individuals with NSCLBP. Further research is needed to establish its clinical relevance according to types of social support, sex, and gender.

My Catastrophizing and Your Catastrophizing: Dyadic Associations of Pain Catastrophizing and the Physical, Psychological, and Relational Well-being of Persons With Endometriosis and Their Partners

OBJECTIVES

Endometriosis, a painful chronic gynecologic condition, contributes to disruptions in multiple areas of life for both those affected and their partner. Pain catastrophizing has been associated with worse pain outcomes and quality of life for women with endometriosis and with more cognitive load for partners. Examining both partners' pain catastrophizing dyadically with our variables of interest will enhance understanding of its associations with the distressing nature of experiencing and responding to pain during sex for couples with endometriosis.

METHODS

Persons with endometriosis experiencing pain during sex and their partners (n=52 couples; 104 individuals) completed online self-report measures of pain catastrophizing, depressive symptoms, sexual satisfaction, and partner responses to pain. Persons with endometriosis reported on pain during sexual activity. Analyses were guided by the Actor-Partner Interdependence Model.

RESULTS

Persons with endometriosis' pain catastrophizing was associated with their higher pain intensity and unpleasantness during sex. When persons with endometriosis reported more pain catastrophizing, they were less sexually satisfied and reported their partners responded more negatively to their pain. When partners reported higher catastrophizing, they were more depressed and responded more negatively to the pain.

DISCUSSION

Consistent with the Communal Coping Model of pain catastrophizing, although meant to elicit support from the environment, the often-deleterious cognitive process of magnifying, ruminating, and feeling helpless about one's pain (or one's partner's pain) is associated with poorer outcomes for the individual with pain and their romantic partner. Implications for pain management include the relevance of involving the partner and attending to the pain cognitions of both members of the couple.

The use of a biopsychosocial model in the treatment of patients with chronic

OBJECTIVE

To explore the available knowledge on the application of biopsychosocial model (BPS) in patients with chronic low back pain (CLBP).

METHODS

A scoping review, including 32 papers that used a BPS to manage adult patients with CLBP, published in any language. Six different databases were searched.

RESULTS

According to the description of the protocols, most of them use BPS for assessment of the patients. In this first stage the most often evaluated were pain and disability, kinesiophobia and quality of life, and work-related factors. The intervention most used associate psychological and physical domains using pain education or cognitive functional therapy and active exercise. Even though was not the most common, in the social domain occupational, behavioral and family interventions were observed.

CONCLUSION

BPS is more often used as combination of physical and psychological aspects, being the social domain restricted to work-related factors. Patien'ts perception of their health status is little explored, and it is suggested that the International Classification of Functioning, Disability and Health be used.

PRACTICE IMPLICATION

Patient perception as well as social factors in addition to occupational ones should be included in the clinical approach of the patient with CLBP and should be further explored in research.

ChatGPT in the development of medical questionnaires. The example of the low back pain

In the last year, Chat Generative Pre-Trained Transformer (ChatGPT), a web software based on artificial intelligence has been showing high potential in every field of knowledge. In the medical area, its possible application is an object of many studies with promising results. We performed the current study to investigate the possible usefulness of ChatGPT in assessing low back pain. We asked ChatGPT to generate a questionnaire about this clinical condition and we compared the obtained questions and results with the ones obtained by other validated questionnaires: Oswestry Disability Index, Quebec Back Pain Disability Scale, Roland-Morris Disability Questionnaire, and Numeric Rating Scale for pain. We enrolled 20 subjects with low back pain and we found important consistencies among the validated questionnaires. The ChatGPT questionnaire showed an acceptable significant correlation only with Oswestry Disability Index and Quebec Back Pain Disability Scale. ChatGPT showed some peculiarities, especially in the assessment of quality of life and medical consultation and treatments. Our study shows that ChatGPT can help evaluate patients, including multilevel perspectives. However, its power is limited, and further research and validation are required.

Unmet needs and depression among spousal caregivers: the mediating role of marital satisfaction

OBJECTIVES

Previous research has identified that unmet needs are associated with adverse mental health outcomes in older adults. However, the unmet needs of older adults' spousal caregivers are unknown. The present study examined the association between unmet needs and depression among spousal caregivers, and whether marital satisfaction mediated this association.

METHODS

We included 1,856 participants who provided care to their spouses with difficulties in activities of daily living (ADL) and instrumental activities of daily living (IADL) from the 2018 China Health and Retirement Longitudinal Survey. Unmet needs of spousal caregivers were assessed as the total number of ADL/IADL tasks with which respondents had unmet needs. Path models were conducted to evaluate the associations between unmet needs, marital satisfaction, and depression. Subgroup analyses by sex were conducted to examine the sex differences regarding the associations.

RESULTS

Spousal caregivers with more unmet ADL/IADL needs reported higher levels of depression (p < 0.001). Additionally, for wife caregivers, unmet ADL/IADL needs were associated with lower marital satisfaction, and lower marital satisfaction was associated with higher degrees of depression, indicating that marital satisfaction partially mediated the association between unmet needs and depression (p < 0.01). However, marital satisfaction did not mediate the association between unmet needs and depression among husband caregivers.

CONCLUSIONS

The mediating effect of marital satisfaction on the association between unmet needs and depression only existed in wife caregivers. Social services should be provided to meet the needs of caregivers with ADL/IADL difficulties, and interventions should be implemented to promote the marital satisfaction of wife caregivers.

Electrical dry needling versus conventional physiotherapy in the treatment of active and latent myofascial trigger points in patients with nonspecific chronic low back pain

Background

Chronic low back pain is considered to be one of the main causes of absenteeism from work and primary and specialized consultations. The symptoms of nonspecific chronic low back pain may be accompanied by the activation of myofascial trigger points in the muscles, together with local and/or referred pain. Electrical dry needling is increasingly used in the treatment of lumbar myofascial pain. Conventional physiotherapy, however, is a popular approach to chronic pathologies, and there is evidence of different modalities of physiotherapy being used in the treatment of chronic low back pain. The aim of this study has been to determine the effectiveness of electrical dry needling versus conventional physiotherapy when applied to active and latent myofascial trigger points in patients with nonspecific chronic low back pain.

Methods

This is a controlled, randomized, two-arm, double-blind study. A total of 92 patients with chronic low back pain (time to onset ≥ 3 months, Roland Morris Disability Questionnaire score ≥ 4) will be recruited from the University of Almería. Participants will be divided into two study groups (n = 40) to receive treatment of low back pain with electrical dry needling and conventional physiotherapy (ischaemic compression, analytic stretching and postural education training dossier). A total of 6 sessions will be administered once a week for 6 weeks. Pain intensity, disability, fear of movement, quality of life, quality of sleep, anxiety and depression, pressure pain threshold, abdominal strength and lumbar mobility will be recorded at 6 weeks (post-immediate) and 2 months after the end of treatment.

Discussion

We believe that an approach including electrical dry needling to chronic low back pain dysfunction will be more effective in these patients. The results of this study will inform clinicians on which type of treatment is more beneficial for patients with chronic low back pain.

Chronic primary or secondary non-inflammatory musculoskeletal pain is associated with disrupted sexual function and relationships: a systematic review

OBJECTIVE

Evidence points to the impact of chronic musculoskeletal pain conditions on sexual function, yet there is little systematic appraisal and synthesis of evidence examining these associations across non-inflammatory conditions. We aimed to systematically review evidence surrounding the association between chronic primary and secondary musculoskeletal pain with intimate relationships and sexual function.

METHODS

Four electronic databases were searched from 1^st January 1990 to 5^th September 2019 for cross-sectional or prospective epidemiologic and qualitative studies among cohorts with chronic primary or secondary non-inflammatory musculoskeletal pain, defined by ICD-11 classification criteria.

RESULTS

Fifty-one eligible studies were included (46 quantitative, 3 qualitative, 2 mixed-methods designs). Sample sizes ranged from 13 to 12,377 and mean age from 32.6 to 69.2 years. Cross-sectional controlled cohort studies consistently reported poorer sexual function outcomes among cohorts with pain relative to comparison groups. Of 15 studies reporting outcomes for the Female Sexual Function Index, 14 demonstrated mean scores ≤26.55 for the pain group, indicating sexual dysfunction. In four studies reporting the International Index of Erectile Function, the pain cohorts demonstrated consistently lower mean subscale scores and the erectile function subscale scores were ≤25.0, indicating erectile dysfunction. Three key themes emerged from a meta-synthesis of qualitative studies: impaired sexual function; compromised intimate relationships; and impacts of pain on sexual identity, body image and self-worth.

CONCLUSION

Sexual dysfunction and negative impacts on intimate relationships are highly prevalent among people with chronic non-inflammatory musculoskeletal pain. Consideration of these associations is relevant to the delivery of holistic, person-centred musculoskeletal pain care.

Assessment of health-related quality of life and patient's knowledge in chronic non-specific low back pain

BACKGROUND

Chronic non-specific low back pain syndrome (cnsLBP) is a severe health problem in developed countries, which has an important effect on patients' quality of life and is highly determined by socio-demographic factors and low back pain specific knowledge. We examined patients' health-related quality of life according to the results of the Short Form Health Survey (SF-36), low back pain knowledge (LBPKQ) and the social determinants of the participants.

METHODS

We carried out our research in the first half of 2015 in Southern Transdanubia, Hungary. The examination included 1155 respondents living with chronic non-specific low back pain. The confidence interval of 95% was used, and the level of. significance was p < 0.05 using SPSS 22.0 software.

RESULTS

The SF-36 questionnaire is suitable for the examination of patients' health-related quality of life (Cronbach's Alpha> 0.76), as the LBPKQ's Cronbach's Alpha was 0.726 also, which showed good validity. Longer-term disease meant a lower health-related quality of life (p < 0.05). A greater decrease of function (Roland Morris scores (RM)) accounts for a lower HRQoL and higher knowledge level. We found significant differences in LBPKQ scores according to sociodemographic parameters. The general health status was positively correlated with LBPKQ (p = 0.024) adjusted for demographic and pain and functional status.

CONCLUSION

The negative effect of the symptoms on patients' quality of life is proved, which is determined by different socio-demographic parameters furthermore by knowledge. Above all could be useful information for professionals to adopt the right interventions.

The Perioperative Symptom Severity of Higher Patient Health Questionnaire-9 Scores Between Genders in Single-Level Lumbar Fusion

BACKGROUND

Preoperative depression is associated with increased perioperative pain, worse physical function, reduced quality of life, and inferior outcomes. Few studies have evaluated depressive symptoms between genders for individuals undergoing minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). The purpose of this investigation was to assess the severity of Patient Health Questionnaire-9 (PHQ-9) scores among patients with depressive symptoms before and after single-level MIS TLIF.

METHODS

A prospective surgical registry was retrospectively reviewed for spine surgeries between March 2016 and December 2018. We included patients with at least mild depressive symptoms (PHQ-9 scores ≥ 5) who underwent primary, single-level MIS TLIF and compared genders using χ2 tests and t tests. Genders were stratified by depressive symptom severity: mild (5-9), moderate (10-14), and moderately severe (≥15) and then analyzed at preoperative and postoperative intervals: 6 weeks, 12 weeks, 6 months, and 1 year. Finally, PHQ-9 scores were validated with a Pearson correlation test against the 12-item Short Form (SF-12) Mental Composite Score (MCS) and the Veterans RAND (VR-12) MCS.

RESULTS

Of 75 subjects, 44.0% were women and the mean age was 49.9 years. The preoperative distribution among PHQ-9 subgroups was 38.7%, 26.6%, and 34.7% for mild, moderate, and moderately severe depressive symptoms, respectively. Among PHQ-9 stratifications both genders demonstrated intermittent statistically significant improvements in PHQ-9 scores. The moderately severe PHQ-9 subgroup had improvement at all postoperative time points. The PHQ-9 scores demonstrated a strong correlation with the SF-12 MCS and VR-12 MCS at all postoperative evaluations.

CONCLUSION

At baseline and by the final 1-year follow-up there were no statistically significant PHQ-9 score differences between genders within any depressive symptom stratifications. Whereas some contend that men and women have substantial mental health differences, this study is aligned with growing evidence that demonstrates similar depressive symptoms between genders.

LEVEL OF EVIDENCE

3.

CLINICAL RELEVANCE

Men and women may be at an equivalent risk for perioperative depressive symptoms.

Reliability and concurrent validity of a mobile application to measure thoracolumbar range of motion in low back pain patients

BACKGROUND

Smartphone devices have been used to measure range of motion (ROM) in different joints.

OBJECTIVE

To verify the concurrent validity of thoracolumbar ROM using a mobile application and a digital inclinometer, as well as the intrarater reliability of individuals with and without back pain.

METHODS

One investigator was responsible for measuring the ROM during the evaluations performed on 20 asymptomatic subjects and 20 symptomatic subjects in two consecutive days.

RESULTS

Regarding to the concurrent validity, the Intraclass Correlation Coefficients (ICC) were classified as very good for all analyzed movements. For intrarater reliability, the mobile application had ICC varying between good and very good for the symptomatic subjects and very good for asymptomatic subjects.

CONCLUSIONS

The mobile application may be considered a valid and reliable tool to assess thoracolumbar ROM for both asymptomatic and chronic low back pain subjects.

The Impact of Cognitive Anxiety and the Rating of Pain on Care Processes in a Vigilance Task: The Important Part Played by Age

Chronic pain is a serious public health problem that has grown exponentially in recent years, which is why it has received the attention of numerous researchers. Most of the studies in the field of chronic pain have focused on care as a mediating variable on the perception of painful stimuli and emotions. Nevertheless, there are very few studies that have gone in the opposite direction. This study's aim is therefore to analyse the impact of emotional variables (anxiety and depression), the rating of pain, and age on vigilance processes in a sample of patients with chronic pain. To do so, the attentional performance of a cohort of 52 patients with chronic pain was measured through the use of a modified dot-probe task. Furthermore, all the participants were evaluated using the following self-report measures: Beck's Depression Inventory-II (BDI-II), the McGill Pain Questionnaire, and the Pain Anxiety Symptoms Scale-20 (PASS-20). Stepwise multiple linear regression analysis revealed a significant negative correlation between the pain rating index and the number of mistakes the participants made during the attention test. There was also a positive and significant correlation with age and another negative and significant correlation with cognitive anxiety regarding the overall performance times during the undertaking of the experimental task. These results point to the importance of a more in-depth understanding of the impact that the emotional variables and other variables such as age have on attentional processes and the rating of pain. Finally, the discussion focuses on the implications these results could have for clinical practice or for future research studies in this field.

Lumbar Spine Fusion Patients' Use of an Internet Support Group: Mixed Methods Study

BACKGROUND

Internet use within health care contexts offers the possibility to provide both health information and peer support. Internet Support Groups (ISGs) for patients may offer advantages, which are not found in face-to-face support. In patients undergoing lumbar spine fusion (LSF), ISGs could have a particular potential, as peer support on the web might bridge the decreased satisfaction with social life and social isolation found within these patients. ISGs might in this way contribute to increasing the functioning and overall health-related quality of life. However, LSF patients may generally belong to a group of citizens not prone to internet and online peer support. However, our knowledge of how LSF patients use ISGs is limited.

OBJECTIVE

The aim of this study was to describe the characteristics of users of an ISG and thematically explore the content of ISG interactions in Danish patients undergoing instrumented LSF because of degenerative spine disorders.

METHODS

Participants were recruited from a randomized controlled trial and included in a prospective cohort with a mixed methods design. Sociodemographic characteristics and information on psychological well-being (symptoms of anxiety and depression) were obtained at baseline and 1 to 5 weeks before surgery. Usage of the ISG was registered from baseline until 3 months after surgery. All posts and comments were collected, and content analysis was performed.

RESULTS

A total of 48 participants comprised the study population, with a mean age of 53 years (range 29-77). Of the participants, 54% (26/48) were female, 85% (41/48) were cohabitating, 69% (33/48) were unemployed, and the majority (69% [33/48]) had secondary education. Approximately one-third of the participants had symptoms of depression (35%, 17/48) and anxiety (29%, 14/48). Overall, 90% (43/48) of the participants accessed the ISG. No correlations were found between sociodemographic characteristics and access to the ISG. Women were more prone to be active users, contributing with posts (P=.04). Finally, active users contributing with posts or comments had viewed more pages, whereas passive users, users without posts or comments, had more interactions with the ISG (P<.001). The ISG contained 180 conversation threads, generating 354 comments. The 180 conversation threads in the ISG were constituted by 671 independent dialogue sequences. On the basis of those 671 dialogue sequences, 7 thematic categories emerged.

CONCLUSIONS

Sociodemographic characteristics were not predictors of ISG use in this study, and active use was found to be gender dependent. Content of interactions on the ISG emerged within 7 thematic categories and focused on social recognition, experience of pain or use of pain medication, experience of physical activity or physical rehabilitation, expression of psychosocial well-being, advising on and exploring the ISG, and employment, which seemed to correspond well with the prevalent occurrence of symptoms of anxiety and depression.

A web-based platform to accommodate symptoms of anxiety and depression by featuring social interaction and animated information in patients undergoing lumbar spine fusion: a randomized clinical trial

BACKGROUND

Approximately one-third of patients undergoing spine surgery have symptoms of anxiety and depression that correlate with pain, disability, and lower health-related quality of life. The use of web-based informative strategies before surgery and principles from cognitive behavioral therapy, have been applied in other patient groups, facilitating mobility and encouraging beneficial coping behavior.

PURPOSE

To examine the effect of a web-based Spine Platform featuring Interaction and Information by Animation (w-SPIINA) on symptoms of anxiety and depression, pain, disability, and health-related quality of life.

STUDY DESIGN

A single-center, two-arm, randomized controlled trial PATIENT SAMPLE: One hundred fourteen consecutive patients scheduled for instrumented lumbar spine fusion due to degenerative disc disease or spondylolisthesis.

OUTCOME MEASURES

Primary outcome was the change in self-reported Hospital Anxiety and Depression Scale (HADS) scores from baseline to 3-month follow-up. Secondary outcomes were change in HADS 1-day before surgery 2days and 6 months after and changes in self-reported disability measured on the Oswestry disability index (ODI), quality of life (EQ-5D-5L questionnaire), and the low back pain rating scale (LBPRS) 2days and 3 and 6 months after surgery.

METHOD

Patients were randomized to either a control group receiving a standard information regimen or an intervention group gaining access to w-SPIINA in addition to the standard regimen. The independent charity Helsefonden contributed $45,000, the Health Research Fund of the Regional Hospital Central Jutland contributed $10,000, and the Toyota foundation contributed $10,000 to remunerate a dedicated investigator. The authors have no conflict of interest to declare.

RESULTS

There was no statistically significant difference within the w-SPIINA group and the control group regarding changes in HADS at 3-month follow-up (p≥.37). Approximately 40% reached minimum clinically important difference (MCID) in the w-SPIINA group on the HADS at 3 months. In the control group 50% reached MCID on anxiety subscale and 35% on the depression subscale at 3 months. No statistically significant differences were found between groups with regard to the overall outcomes at any of the predefined time points.

CONCLUSION

Providing patients with access to w-SPIINA in addition to a standard information regimen had no additional effect on HADS and patient-reported outcomes1day before, 2days, 3 or 6 months after surgery. However, a high compliance and degree of interaction with w-SPIINA indicates that this mode of web-based support could be applicable in this group of patients.

Anxiety and depression in spine surgery-a systematic integrative review

BACKGROUND

Symptoms of preoperative anxiety and depression occur in approximately one-third of patients with chronic back pain undergoing surgery. In the last 2 decades, several studies have established that preoperative anxiety and depression are important outcome predictors of greater pain and physical impairments, and lower health-related quality of life in patients undergoing spine surgery. To accommodate symptoms of anxiety and depression and thereby better surgical outcomes, we need to identify factors associated with these symptoms.

PURPOSE

We aimed to identify factors associated with symptoms of anxiety and depression in adults both before and after undergoing spinal surgery.

STUDY DESIGN

An integrative literature review was carried out.

METHODS

The independent charity Helsefonden supported this literature review by contributing $45,000 to remunerate a dedicated investigator. A systematic literature search was conducted in PubMed, CINAHL, PsycINFO, Embase, Scopus, Cochrane, and Web of Science. A three-step selection and assessment process was conducted; titles and abstracts of 1,124 articles were skimmed for relevance and of these, 53 articles were found to be of relevance and were read in full. Articles not meeting the inclusion criteria (n=26) were excluded. The 31 articles were critically appraised for methodological validity; 14 of these were synthesized and analyzed using a convergent qualitative design to transform both qualitative and quantitative articles into qualitative findings.

RESULTS

Fourteen studies were included, reporting results based on 4,833 participants, 3,017 men and 1,816 women, whose mean age was approximately 49 years. From these results, we extracted 75 individual findings, which we then divided into five categories of factors associated with anxiety and depression both before and after undergoing spine surgery: pain, information, disability, employment, and mental health.

CONCLUSIONS

Five categories of interacting factors that influenced symptoms of anxiety and depression both before and after surgery were identified: pain, lack of information, disability, return to work, and mental health. Information appears to have a regulating effect on anxiety and depression.

Beyond solicitousness: a comprehensive review on informal pain-related social support

Adults with chronic pain cite social support (SS) as an important resource. Research has mostly focused on general SS or pain-specific solicitousness, resulting in a limited understanding of the role of SS in pain experiences. Drawing on SS theoretical models, this review aimed to understand how pain-related SS has been conceptualized and measured and how its relationship with pain experiences has been investigated. Arksey and O'Malley scoping review framework guided the study. A database search (2000-2015) was conducted in PsycINFO, CINAHL, MEDLINE, and EMBASE using a combination of subject headings/keywords on pain and SS; 3864 citations were screened; 101 full texts were assessed for eligibility; references of 52 papers were hand searched. Fifty-three studies were included. Most studies were either a-theoretical or drew upon the operant conditioning model. There are several self-report measures and observational systems to operationalize pain-related SS. However, the Multidimensional Pain Inventory remains the most often used, accounting for the centrality of the concept of solicitousness in the literature. Most studies focused on individuals with chronic pain self-report of spousal pain-related SS and investigated its main effects on pain outcomes. Only a minority investigated the role of pain SS within the stress and coping process (as a buffer or mediator). Little is known about mediating pathways, contextual modulation of the effectiveness of SS exchanges, and there are practically no SS-based intervention studies. Drawing on general SS models, the main gaps in pain-related SS research are discussed and research directions for moving this literature beyond solicitousness are proposed.

Association Between Symptoms of Central Sensitization and Cognitive Behavioral Factors in People With Chronic Nonspecific Low Back Pain: A Cross-sectional Study

OBJECTIVE

The objective of this cross-sectional study was to analyze the relationship between symptoms of central sensitization (CS) and important cognitive behavioral and psychosocial factors in a sample of patients with chronic nonspecific low back pain.

METHODS

Participants with chronic nonspecific low back pain for at least 3 months were included in the study. They completed several questionnaires and a functional test. Pearson's correlation was used to analyze associations between symptoms of CS and pain behavior, functioning, pain, pain catastrophizing, kinesiophobia, and illness perceptions. Additionally, a between-group analysis was performed to compare patients with and without clinically relevant symptoms of CS.

RESULTS

Data from 38 participants were analyzed. Significant associations were found between symptoms of CS and all other outcomes, especially current pain (r = 0.510, P = .001), mean pain during the past 7 days (r = 0.505, P = .001), and pain catastrophizing (r = 0.518, P = .001). Patients with clinically relevant symptoms of CS scored significantly worse on all outcomes compared with persons without relevant symptoms of CS, except on functioning (P = .128).

CONCLUSIONS

Symptoms of CS were significantly associated with psychosocial and cognitive behavioral factors. Patients exhibiting a clinically relevant degree of symptoms of CS scored significantly worse on most outcomes, compared with the subgroup of the sample with fewer symptoms of CS.

Understanding Monitoring Technologies for Adults With Pain: Systematic Literature Review

BACKGROUND

Monitoring of patients may decrease treatment costs and improve quality of care. Pain is the most common health problem that people seek help for in hospitals. Therefore, monitoring patients with pain may have significant impact in improving treatment. Several studies have studied factors affecting pain; however, no previous study has reviewed the contextual information that a monitoring system may capture to characterize a patient's situation.

OBJECTIVE

The objective of this study was to conduct a systematic review to (1) determine what types of technologies have been used to monitor adults with pain, and (2) construct a model of the context information that may be used to implement apps and devices aimed at monitoring adults with pain.

METHODS

A literature search (2005-2015) was conducted in electronic databases pertaining to medical and computer science literature (PubMed, Science Direct, ACM Digital Library, and IEEE Xplore) using a defined search string. Article selection was done through a process of removing duplicates, analyzing title and abstract, and then reviewing the full text of the article.

RESULTS

In the final analysis, 87 articles were included and 53 of them (61%) used technologies to collect contextual information. A total of 49 types of context information were found and a five-dimension (activity, identity, wellness, environment, physiological) model of context information to monitor adults with pain was proposed, expanding on a previous model. Most technological interfaces for pain monitoring were wearable, possibly because they can be used in more realistic contexts. Few studies focused on older adults, creating a relevant avenue of research on how to create devices for users that may have impaired cognitive skills or low digital literacy.

CONCLUSIONS

The design of monitoring devices and interfaces for adults with pain must deal with the challenge of selecting relevant contextual information to understand the user's situation, and not overburdening or inconveniencing users with information requests. A model of contextual information may be used by researchers to choose possible contextual information that may be monitored during studies on adults with pain.

Short-term effectiveness of spinal manipulative therapy versus functional technique in patients with chronic nonspecific low back pain: a pragmatic randomized controlled trial

BACKGROUND CONTEXT

Chronic low back pain (LBP) is a prevalent condition associated with pain, disability, decreased quality of life, and fear of movement. To date, no studies have compared the effectiveness of spinal manipulation and functional technique for the management of this population.

PURPOSE

This study aimed to compare the effectiveness of spinal manipulation and functional technique on pain, disability, kinesiophobia, and quality of life in patients with chronic LBP.

STUDY DESIGN/SETTING

A single-blind pragmatic randomized controlled trial conducted in a university research clinic was carried out.

PATIENT SAMPLE

Sixty-two patients (62% female, age: 45±7) with chronic LBP comprised the patient sample.

OUTCOME MEASURES

Data on disability (Roland-Morris Disability Questionnaire [RMQ], Oswestry Low Back Pain Disability Index [ODI]), pain intensity (Numerical Pain Rate Scale [NPRS]), fear of movement (Tampa Scale of Kinesiophobia [TSK]), quality of life (Short Form-36 [SF-36] quality of life questionnaire), isometric resistance of abdominal muscles (McQuade test), and spinal mobility in flexion (finger-to-floor distance) were collected at baseline immediately after the intervention phase and at 1 month postintervention by an assessor blinded to group allocation of the patients.

METHODS

Patients were randomly assigned to the spinal manipulative therapy group or the functional technique group and received three once-weekly sessions.

RESULTS

In comparison to patients receiving functional technique, those receiving spinal manipulation experienced statistically, although not clinically, significant greater reductions in terms of RMQ (standardized mean difference in score changes between groups at post-treatment: 0.1; at 1 month: 0.1) and ODI (post-treatment: 2.9; at 1 month: 1.4). Linear longitudinal analysis showed a significant improvement in both groups over time for RMQ (manipulative: F=68.51, p<.001; functional: F=28.58, p<.001) and ODI (manipulative: F=104.66, p<.001; functional: F=32.15, p=.001). However, significant treatment-by-time interactions were not detected for pain intensity (p=.488), TSK (p=.552), any domains of the SF-36 quality of life questionnaire (p≤.164), McQuade test (p=.512), and finger-to-floor distance (p=.194). Differences between and within groups were not clinically meaningful in any of the reported measures.

CONCLUSIONS

In comparison to functional technique, spinal manipulative therapy showed greater reduction in disability in patients with chronic LBP, but not in terms of pain, fear of movement, quality of life, isometric resistance of trunk flexors, or spinal mobility. However, differences in disability were not clinically meaningful; therefore, spinal manipulative therapy did not result in any clinically important short-term benefits over functional technique therapy. In addition, as neither group met the threshold for minimum clinically important difference following treatment, neither treatment resulted in a clinically meaningful benefit.

The Communal Coping Model of Pain Catastrophizing in Daily Life: A Within-Couples Daily Diary Study

The Communal Coping Model characterizes pain catastrophizing as a coping tactic whereby pain expression elicits assistance and empathic responses from others. Married couples (N = 105 couples; 1 spouse with chronic low back pain) completed electronic daily diary assessments 5 times/day for 14 days. In these diaries, patients reported pain catastrophizing, pain, and function, and perceived spouse support, perceived criticism, and perceived hostility. Non-patient spouses reported on their support, criticism, and hostility directed toward patients, as well as their observations of patient pain and pain behaviors. Hierarchical linear modeling tested concurrent and lagged (3 hours later) relationships. Principal findings included the following: a) within-person increases in pain catastrophizing were positively associated with spouse reports of patient pain behavior in concurrent and lagged analyses; b) within-person increases in pain catastrophizing were positively associated with patient perceptions of spouse support, criticism, and hostility in concurrent analyses; c) within-person increases in pain catastrophizing were negatively associated with spouse reports of criticism and hostility in lagged analyses. Spouses reported patient behaviors that were tied to elevated pain catastrophizing, and spouses changed their behavior during and after elevated pain catastrophizing episodes. Pain catastrophizing may affect the interpersonal environment of patients and spouses in ways consistent with the Communal Coping Model.

PERSPECTIVE

Pain catastrophizing may represent a coping response by which individuals' pain expression leads to assistance or empathic responses from others. Results of the present study support this Communal Coping Model, which emphasizes interpersonal processes by which pain catastrophizing, pain, pain behavior, and responses of significant others are intertwined.

Association of pain and depression in those with chronic low back pain: the mediation effect of patient sexual functioning

OBJECTIVES

One theoretical model suggests that the pathway from pain to depression is through the disruption of social and relationship function. This study sought to test this hypothesis by considering the mediating effect of sexual functioning on the association between pain intensity and depressive symptoms in sexually active patients with chronic low back pain.

MATERIALS AND METHODS

This was a cross-sectional study on consecutive patients attending a chronic pain management clinic in Iran. All measures (pain intensity, depressive symptoms, sex-specific sexual function) were obtained by a self-report questionnaire, completed by patients while attending the clinic. Sobel testing, including bias-corrected bootstrapping, was used to produce 95% confidence intervals (95% CI) to test the mediating effect of sexual function.

RESULTS

A total of 742 patients (351 men, 391 women) took part in this study. Both the male and female mediation models showed a significant association between pain intensity and depressive symptoms, and both the models were significantly mediated by sexual functioning (P<0.001). Effect size calculations show a medium to large effect on male patients (κ 0.23; 95% CI, 0.15-0.39) and a medium effect for female patients (κ 0.16; 95% CI, 0.06-0.28). Both the models accounted for over 50% of the variance in depressive symptoms (model R).

DISCUSSION

This study has shown that sexual functioning significantly mediates the relationship between pain intensity and depressive symptoms in sexually active patients with chronic low back pain. Clinicians may wish to consider the assessment of sexual functioning within this patient group and align treatments that address sexual dysfunction and general pain management.

'I think positivity breeds positivity': a qualitative exploration of the role of family members in supporting those with chronic musculoskeletal pain to stay at work

Background

It is proposed that family members are important sources of support in helping those with chronic musculoskeletal pain to remain at work, but the phenomenon remains largely unexplored. The aim of this study was to examine the extent and nature of support provided by family members in this respect.

Methods

Qualitative data were collected from workers and their ‘significant others’ (spouses/partners/close family members) in two un-related studies focused on working with pain; one conducted in the United Kingdom (n = 10 dyads) and one in the Netherlands (n = 21 dyads). Thematic analysis techniques were applied to both sets of data independently, and findings were then assimilated to establish common themes.

Results

Findings were broadly similar in both studies. Workers acknowledged significant other support in helping them to manage their pain and remain at work, and their descriptions of the type of support provided and required were echoed by their significant others. Three common themes were identified - ‘connectivity’, ‘activity’ and ‘positivity’. Worker and significant other responses were largely congruent, but significant others provided more in-depth information on the nature of their support, their concerns and the impact on their relationship.

Conclusions

This research presents novel insights about the specific contribution made by significant others in helping their relatives with chronic musculoskeletal pain to stay at work. These findings add to the under-represented ‘social’ dimension of the biopsychosocial model currently applied to our understanding and treatment of pain, and point to harnessing support from significant others as a potentially effective management strategy.

Psychosocial aspects of everyday life with chronic musculoskeletal pain: A systematic review

Background and objective Chronic pain is a growing phenomenon worldwide. It is considered a medical problem because, besides the socio-economic issues involved, pain is often accompanied by psychosocial problems. Apart from the physical pain, living with chronic pain has many additional consequences. People living with chronic pain generally suffer from other physical and psychological consequences. The impact of chronic pain varies enormously between individuals, but the suffering is frequently pervasive and detrimental. The objective of this study was to review the evidence concerning, ways in which people living with chronic pain are affected in their everyday lives. Methods Electronic databases Scopus, Cinahl and PsycINFO were searched from 2008 to September 2012 using a 'building blocks' approach and reference lists were scanned. PubMed was also searched and checked for duplicates compared to Scopus, Cinahl and PsycINFO. Data were extracted from included studies and methodological quality assessed with a view to exploring quality differences. To guide the review and interpretation, individual components of methodological quality were compared against a checklist. A narrative synthesis was formulated involving three categories: (1) clinical aspects, (2) everyday life aspects and (3) interpersonal aspects. Results The search strategy identified 1140 citations; one study was found during the preliminary searching through references, and a search of reference lists provided five publications. Of these, 24 publications, representing 23 populations, met the inclusion criteria. In total, there were 22 cross-sectional studies and 2 cohort studies. Study populations ranged from 74 to 3928 participants and were heterogeneous in nature across studies with respect to age, duration and localisations of pain and outcome measures. We found a general consensus that life with chronic pain was associated with higher prevalence and higher levels of depression and diagnoses of widespread pain and nonspecific pain are more clearly associated with depression than is specific pain. The results of link between chronic pain and anxiety and stress were not obvious. Overall, there is plausible evidence to suggest a positive relationship between chronic pain and disability and the evidence is stronger for a significant positive association between nonspecific pain and disability, compared to specific pain. It can be summarized that there is a lack of evidence for a relationship between intensity of pain and quality of life. However, there is evidence that nonspecific pain is more compellingly associated with low quality of life than is specific pain. The evidence of a positive relation between pain and problems in close relations is not convincing but there is an indication to suggest that there is a pain-related issue regarding participation in many social aspects of everyday life. Conclusion Besides the pain itself, people living with chronic pain are affected in other aspects of life. In particular, it is evident that they experience challenges with respect to depressive thoughts, disability, lower quality of life and conflicts in close relationships. Implications When designing interventions for people with chronic pain, it is essential to take into consideration the fact that living with chronic pain has far-reaching consequences beyond the pain suffered.

Impact of pain intensity on relationship quality between couples where one has back pain

Objectives

To investigate associations of pain intensity in those with long‐term back pain, with their partners' rating of key constructs of relationship quality: cohesion (activities together), consensus (affection, sexual relations), satisfaction (conflict, regrets).

Methods

Self‐report questionnaires on relationship quality (partner‐rated), depression (partner‐rated), relationship length, and pain intensity (patient‐rated) were collected from back pain patients and their partners (N = 71). Linear regression was carried out to test for associations, standardized coefficients (β) and 95% confidence intervals (95% CI) are reported.

Results

There was no main effect between patient pain intensity and partner rating of relationship quality. However, partner ratings of relationship quality were lower if the partner reported increasing depressive symptoms. Adjusting for the effects of partner depression show that ratings of consensus (affection, sexual relations) from partners were actually higher with increasing levels of pain intensity in patients (β 0.54, 95% CI 0.17 to 0.90, P < 0.01). Furthermore lower ratings of consensus were reported where patient pain intensity interacted with partner depression (β −0.11, 95% CI—0.19 to −0.03, P < 0.05).

Conclusions

These findings illustrate the association of pain outcomes beyond the patient within a primary care sample. Moderators of the responses about the relationship construct of consensus generated by partners appear to be partners' own level of depressive symptoms and whether their depressive symptoms are associated with the patients' pain intensity. Consultations should consider the social context of patients with pain.

The relationship between cortical excitability and pain catastrophizing in myofascial pain

Pain catastrophizing regularly occurs in chronic pain patients. It has been suggested that pain catastrophizing is a stable, person-based construct. These findings highlight the importance of investigating catastrophizing in conceptualizing specific approaches for pain management. One important area of investigation is the mechanism underlying pain catastrophizing. Therefore, this study explored the relationship between a neurophysiological marker of cortical excitability, as assessed by transcranial magnetic stimulation, and catastrophizing, as assessed by the Brazilian Portuguese Pain Catastrophizing Scale, in patients with chronic myofascial pain syndrome. The Pain Catastrophizing Scale is a robust questionnaire used to examine rumination, magnification and helplessness that are associated with the experience of pain. We include 24 women with myofascial pain syndrome. The Brazilian Portuguese Pain Catastrophizing Scale and cortical excitability were assessed. Functional and behavioral aspects of pain were evaluated with a version of the Profile of Chronic Pain scale and by multiple pain measurements (eg, pain intensity, pressure pain threshold, and other quantitative sensory measurements). Intracortical facilitation was found to be significantly associated with pain catastrophizing (β = .63, P = .001). Our results did not suggest that these findings were influenced by other factors, such as age or medication use. Furthermore, short intracortical inhibition showed a significant association with pressure pain threshold (β = .44, P = .04). This study elaborates on previous findings indicating a relationship between cortical excitability and catastrophizing. The present findings suggest that glutamatergic activity may be associated with mechanisms underlying pain catastrophizing; thus, the results highlight the need to further investigate the neurophysiological mechanisms associated with pain and catastrophizing.

PERSPECTIVE

This study highlights the relationship between cortical excitability and catastrophizing. Cortical measures may illuminate how catastrophizing responses may be related to neurophysiological mechanisms associated with chronic pain.

Massage on experimental pain in healthy females: A randomized controlled trial

This randomized controlled study evaluated the effect of massage on affect, relaxation, and experimental pain induced by electrical stimulation. Participants were 96 healthy women ( M age = 20.13 ± 5.93 years; 84.4% White) randomly assigned to a 15-minute no-treatment control, guided imagery, massage or massage plus guided imagery condition. Multilevel piecewise modeling revealed no group differences in pain intensity, threshold, or tolerance. The two massage conditions generally reported decreased pain unpleasantness, lower unpleasant affect, maintenance of pleasant affect, and increased relaxation compared to the no-treatment condition. The results suggest that massage may alter immediate affective qualities in the context of pain.

"I can't get no satisfaction": deep dyspareunia and sexual functioning in women with rectovaginal endometriosis

OBJECTIVE

To assess the impact of rectovaginal endometriosis on pain at intercourse and sexual functioning.

DESIGN

Case-control study.

SETTING

Academic department.

PATIENT(S)

Case subjects were women with rectovaginal endometriosis (n = 100), and control subjects were women with a surgical diagnosis of peritoneal and/or ovarian endometriosis (n = 100) or without endometriosis (n = 100).

INTERVENTION(S)

Questionnaires (visual analogue scale [VAS] and revised Sabbatsberg Sexual Self-Rating Scale [SRS]).

MAIN OUTCOME MEASURE(S)

Frequency and severity of deep dyspareunia and sexual functioning.

RESULT(S)

Deep dyspareunia was reported by 67/100 (67%) women in the rectovaginal endometriosis group, 52/99 (53%) in the peritoneal and/or ovarian endometriosis group, and 24/93 (26%) in the nonendometriosis group. Mean ± SD dyspareunia VAS scores were, respectively, 44 ± 34, 30 ± 32, and 13 ± 26. Women in both endometriosis groups performed significantly worse than those in the nonendometriosis group in several SRS subdomains. No significant difference in overall SRS score was detected between women in the two endometriosis groups.

CONCLUSION(S)

Women with endometriosis experienced more frequent and severe deep dyspareunia and worse sexual functioning compared with women without endometriosis, whereas differences between women with diverse endometriosis forms were marginal.

Kinesio Taping reduces disability and pain slightly in chronic non-specific low back pain: a randomised trial

QUESTION

Does Kinesio Taping reduce disability, pain, and kinesiophobia in people with chronic non-specific low back pain?

DESIGN

Randomised trial, with concealed allocation, assessor blinding, and intention-to-treat analysis.

PARTICIPANTS

Sixty adults with chronic non-specific low back pain.

INTERVENTION

The experimental intervention was Kinesio Taping over the lumbar spine for one week; the control intervention was sham taping.

OUTCOME MEASURES

The following outcomes were measured at baseline, immediately after the week with the tape in situ, and four weeks later: Oswestry Disability Index, Roland- Morris Low Back Pain and Disability Questionnaire, pain on a 10-cm visual analogue scale, Tampa kinesiophobia scale, trunk flexion range of motion, and the McQuade test of trunk muscle endurance.

RESULTS

At one week, the experimental group had significantly greater improvement in disability, by 4 points (95% CI 2 to 6) on the Oswestry score and by 1.2 points (95% CI 0.4 to 2.0) on the Roland-Morris score. However, these effects were not significant four weeks later. The experimental group also had a greater decrease in pain than the control group immediately after treatment (mean between-group difference 1.1cm, 95% CI 0.3 to 1.9), which was maintained four weeks later (1.0cm, 95% CI 0.2 to 1.7). Similarly trunk muscle endurance was significantly better at one week (by 23 sec, 95% CI 14 to 32) and four weeks later (by 18 sec, 95% CI 9 to 26). Other outcomes were not significantly affected.

CONCLUSION

Kinesio Taping reduced disability and pain in people with chronic non-specific low back pain, but these effects may be too small to be clinically worthwhile.

Physical and psychosocial predictors of functional trunk capacity in older adults with and without low back pain

OBJECTIVE

The purpose of this study was to determine the physical and psychosocial predictors of functional trunk capacity in a group of healthy elderly individuals and a group of elderly patients with chronic low back pain (LBP).

METHODS

The study was done in Canada and included 61 community-dwelling elderly individuals (29 patients with nonspecific chronic LBP and 32 healthy participants) who performed maximal trunk endurance and force tasks. Participants completed various psychologic and functional questionnaires. Sequential linear regression analyses were performed with functional capacity results (endurance and force) as dependent variables and questionnaire scores as independent variables.

RESULTS

Endurance time and peak force were significantly lower in patients compared with healthy elderly individuals (all P values < .001), whereas pain-related fear of movement, pain catastrophizing, and depression levels were higher in patients than their healthy counterpart (all P values < .001). After adjusting for physical activity and disability levels (R(2) = 33.7%-50.5% in patients; R(2) = 0.1%-5.7% in healthy individuals), none of the psychologic questionnaire could explain variations observed in functional capacity in patients (R(2) changes, 4.8%-6.7%) and in healthy participants (R(2) changes, 5.2%-10.6%).

CONCLUSION

Patients showed diminished functional capacity compared with healthy participants. Moreover, physical activity levels represent the most important predictors of functional capacity in elderly patients with LBP.

The role of relationship quality and perceived partner responses with pain and disability in those with back pain

Objective

The objectives of this study were to investigate the associations of key constructs of relationship quality (cohesion, consensus, and satisfaction) and perceived partner responses to pain behavior (e.g., solicitous and negative responses) with the outcomes of pain and disability in those with long-term low back pain, and to explore the role of the patient's depressive symptom mood state on those associations.

Methods

Self-report questionnaires on pain intensity, disability, relationship quality, perceived partner reactions to pain, and depressive symptoms were collected from participants (N = 174) taking part in a longitudinal study on low back pain within a primary care sample.

Results

Participants reporting more consensus (e.g., agreement about sexual intimacy, level of affection) in their relationships had significantly higher pain intensity (P = 0.03), and solicitous partner responses (P = 0.04) were significantly positively associated with disability levels. However, the findings for pain intensity were only present in those with higher levels of depression, while the association of solicitous responses with disability was only significant in those with lower levels of depression, indicating a suppression effect of depression on pain and disability.

Conclusions

Depressive symptoms play a significant role in determining the associations between relationship quality, perceived partner reactions, and pain and disability. The relationship construct of consensus and perceived solicitous responses were associated with pain and disability. These findings illustrate the importance of social context and patient mood state on the outcomes for those with low back pain.

Catastrophizers with chronic pain display more pain behaviour when in a relationship with a low catastrophizing spouse

The present study examined the relationship between couple concordance of catastrophizing and adverse pain outcomes. Possible mechanisms underlying the relationship between couple concordance of catastrophizing and pain outcomes were also explored. Fifty-eight couples were recruited for the study. The chronic pain patients were filmed while lifting a series of weighted canisters. The spouse was later invited to view the video and answer questions about the pain experience of their partner. Median splits on Pain Catastrophizing Scale scores were used to create four 'catastrophizing concordance' groups: low catastrophizing patient-low catastrophizing spouse; low catastrophizing patient-high catastrophizing spouse; high catastrophizing patient-low catastrophizing spouse; and high catastrophizing patient-high catastrophizing spouse. Analyses revealed that high catastrophizing pain patients who were in a relationship with a low catastrophizing spouse displayed more pain behaviours than patients in all other groups. These findings suggest that high catastrophizing chronic pain patients may need to increase the 'volume' of pain communication to compensate for low catastrophizing spouses' tendency to underestimate the severity of their pain experience. Patients' perceived solicitousness and punitive response from the spouse could not explain the group differences in pain behaviour. Theoretical and clinical implications of the findings are discussed.

Causal attributions and alexithymia in female patients with fibromyalgia or chronic low back pain

AIMS

Our general objective was to assess the psychological symptoms and the types of causal attributions linked to the symptoms among women chronic pain.

METHODS

70 fibromyalgia (FM) patients, 56 chronic low back pain (CLBP) patients and 72 healthy controls were assessed within a general hospital setting, using the Toronto Alexithymia Scale, Brief Symptom Inventory and Symptom Interpretation Questionnaire. Three-way analysis of variance and chi-square tests were used for inter-group comparisons, followed by multivariate correlation, covariate analysis and linear regression.

RESULTS

Alexithymia, somatization, depression, anxiety and hostility scores were significantly higher in FM patients relative to CLBP patients and healthy controls (P < 0.05). Alexithymia was linked to psychological attributions in FM patients and to somatic attributions in CLBP patients. Psychological attributions, the number of symptoms and difficulty in describing emotions were related to increased anxiety in FM patients. Depression, anxiety and somatization were significantly increased in subjects with high alexithymia scores in the FM group. There was no difference between groups regarding causal attributions.

CONCLUSIONS

Causal attributions do not seem to have distinctive features between functional somatic syndromes like FM and CLBP, though differences might exist between groups as to the effects of coexisting psychological distress symptoms like anxiety and depression.
