Association of Pharmacologic Treatment of Depression/Anxiety With Initial Patient-Reported Outcome Measures in Patients With Hip and Knee Osteoarthritis

INTRODUCTION

Depression and anxiety are common comorbidities that may exacerbate osteoarthritis (OA)-related pain. We aim to evaluate the effect of pharmacologic treatment of depression/anxiety on hip and knee patient-reported outcome measures (PROMs).

METHODS

A multi-institutional PROMs database was queried for patients with depression or anxiety and hip or knee OA who completed a PROMs questionnaire at an initial orthopaedic visit between January 2015 and March 2023. Data on demographics, comorbidities, and duration of pharmacologic treatment of depression/anxiety were obtained. Patients were stratified into three cohorts based on treatment duration. PROMs were compared across cohorts.

RESULTS

Two thousand nine hundred sixty patients who completed PROMs at their initial orthopaedic visit had both OA and depression/anxiety. One hundred thirty-four (4.5%) received pharmacologic treatment of depression/anxiety for < 1 year, versus 196 (6.6%) for more than 1 year. In unadjusted analyses, patients with pharmacologic treatment had significantly lower Patient-Reported Outcomes Measurement Information System (PROMIS)-Physical (39.8 [IQR 34.9, 44.9] vs 42.3 [37.4, 47.7], P < 0.001) and PROMIS-Mental (43.5 [36.3, 50.8] vs 48.3 [41.1, 53.3], P < 0.001) scores than those without treatment. After adjusting for demographics and comorbidities, only differences in PROMIS-Mental scores remained statistically significant, with pharmacologic treatment associated with lower scores (β = -2.26, 95% CI, [-3.29, -1.24], P < 0.001). On secondary analysis including duration of pharmacologic treatment, < 1 year of treatment was associated with significantly lower PROMIS-Mental scores than those not treated (β = -4.20, 95% CI [-5.77, -2.62], P < 0.001) while scores of patients with more than 1 year of treatment did not differ significantly from those without treatment.

CONCLUSION

:Our results indicate that pharmacologic treatment of depression/anxiety is associated with improved psychological health but not with improved physical symptoms related to OA. We observed a nonsignificant trend that patients with depression/anxiety who warrant pharmacologic treatment tend to have worse physical symptoms than those who do not; however, unadjusted analyses suggest this is a complex relationship beyond the isolated effect of pharmacologic treatment.

The predicting factors of chronic pain among nursing students: a national study in Iran

BACKGROUND

Nursing students are faced with a variety of challenges that demand effective cognitive and emotional resources. The physical and psychological well-being of the students plays a key part in the public health of the community. Despite the special lifestyle of nursing students, few studies have addressed chronic pain in this population. Accordingly, the present study aims to identify the predictors of chronic pain among nursing students.

METHODS

This cross-sectional study was conducted on 1,719 nursing students aged 18-42 years, between February and November 2019. Sampling was carried out in several stages. Data were collected using seven instruments, namely a demographics survey, the characteristics of chronic pain form, Spielberger State-Trait Anxiety Inventory (STAI), the Patient Health Questionnaire-9 (PHQ-9), the Bar-on Emotional Quotient Inventory, Academic Satisfaction Scale, and Procidano and Heller Social Support Scale. Descriptive statistics, multinomial logistic regression, and regression models were used to describe the characteristics of the pain and its predictive factors.

RESULTS

The average age of the participants was 22.4 ± 2.96 years. The results of univariate analysis showed that gender (P = 0.506), mother's education (P = 0.056, P = 0.278, P = 0.278), father's education (P = 0.817, P = 0.597, P = 0.41), place of residence (P = 0.215), depression (P = 0.501), grade point average (P = 0.488), academic satisfaction (P = 0.183) and chronic pain weren't significantly correlated with chronic pain in nursing students. The results of the multiple logistic regression models showed that chronic pain was positively correlated with age, social support, state anxiety, and trait anxiety (OR = 1.07, 95% CI: 1.02-1.12; OR = 0.95, 95% CI: 0.93-0.97; OR = 1.03, 95% CI: 1.02-1.05; and OR = 1.97, 95% CI: 0.95-1.99; respectively).

CONCLUSION

The prevalence of chronic pain was relatively high in these students. In addition, age, social support, and anxiety could be important factors in the development or persistence of chronic pain in nursing students. The results also provided basic and essential information about the contributing factors in this area. However, consideration of factors such as referral for treatment, home medications for pain relief, and outcomes of chronic pain are suggested in future longitudinal studies.

Wellness of patients with chronic pain is not only about pain intensity

OBJECTIVE

Attaining good outcomes in the management of chronic pain remains a clinical challenge. This study aimed to investigate the relationships between - and the contribution of - pain and related conditions to the wellness of these patients.

DESIGN

A secondary analysis of database of patients with chronic pain treated with medical cannabis (MC) to carry out a one-year prospective follow-up study was conducted. Questionnaires were completed before (T₀ ), six (T₆ ), and twelve (T₁₂ ) months after MC initiation. Data included patients' demographics and questionnaires related to three latent factors: pain intensity measures, related conditions (catastrophizing, sleep disturbance, anxiety, and depression), and wellness parameters (quality-of-life, disability, subjective-health-state). Weighted average of the observed variables (WOBs) were calculated for each latent factor. Longitudinal structural equation modeling (SEM) and mediation analyses were performed to identify predictors and interrelations between the WOBs, respectively.

RESULTS

Participants included 510 patients. All variables were significantly improved from T₀ to T₆ and T₁₂ . SEM revealed that related conditions, and to a lesser extent pain, predicted wellness at T₀ , T₆ , and T₁₂ (related conditions: β₀  = 0.55, p < 0.001; β₆  = 0.54, p < 0.001; and β₁₂  = 0.51, p < 0.001; pain: β₀  = 0.42, p < 0.001; β₆  = 0.18, p < 0.001; and β₁₂  = 0.25, p < 0.001). Mediation analyses demonstrated that the effect of WOB-related conditions was greater than WOB-pain on wellness.

CONCLUSION

Wellness of patients with chronic pain can be determined not only by pain itself but even more so by the severity of related conditions. Thus, considering a broad spectrum of pain measures and related conditions seems relevant for improving the wellness of patients with chronic pain.

Examining the roles of depression, pain catastrophizing, and self-efficacy in quality of life changes following chronic pain treatment

Background

Adults with chronic pain have a lower quality of life (QOL) compared to the general population. Chronic pain requires specialized treatment to address the multitude of factors that contribute to an individual's pain experience, and effectively managing pain requires a biopsychosocial approach to improve patients' QOL.

Aim

This study examined adults with chronic pain after a year of specialized treatment to determine the role of cognitive markers (i.e., pain catastrophizing, depression, pain self-efficacy) in predicting changes in QOL.

Methods

Patients in an interdisciplinary chronic pain clinic (N = 197) completed measures of pain catastrophizing, depression, pain self-efficacy, and QOL at baseline and 1 year later. Correlations and a moderated mediation were completed to understand the relationships between the variables.

Results

Higher baseline pain catastrophizing was significantly associated with increased mental QOL (b = 0.39, 95% confidence interval [CI] 0.141; 0.648) and decreased depression (b = -0.18, 95% CI -0.306; -0.052) over a year. Furthermore, the relationship between baseline pain catastrophizing and the change in depression was moderated by the change in pain self-efficacy (b = -0.10, 95% CI -0.145; -0.043) over a year. Patients with high baseline pain catastrophizing reported decreased depression after a year of treatment, which was associated with greater QOL improvements but only in patients with unchanged or improved pain self-efficacy.

Conclusions

Our findings highlight the roles of cognitive and affective factors and their impact on QOL in adults with chronic pain. Understanding the psychological factors that predict increased mental QOL is clinically useful, because medical teams can optimize these positive changes in QOL through psychosocial interventions aimed at improving patients' pain self-efficacy.

Mental health among patients with chronic musculoskeletal pain and its relation to number of pain sites and pain intensity, a cross-sectional study among primary health care patients

BACKGROUND

Chronic musculoskeletal pain (CMP) is characterised by pain related to the muscles or the joints with a duration of three months or more and is associated with high symptomatic burden in patients in primary health care. CMP is commonly associated with impaired mental health, which may affect the rehabilitation process. The primary aim of this study was to compare symptoms of anxiety, depression, fatigue, and insomnia in patients in primary health care with and without CMP. The secondary aim was to assess difference in mental health symptoms related to number of pain sites and pain intensity.

METHODS

This cross-sectional study was conducted in Trondheim, Norway. All patients aged 21-58 from randomly selected general practitioners (GPs) were invited to participate. Participants were classified into two groups according to presence of CMP. Symptoms of anxiety, depression, fatigue, and insomnia were assessed by the Hospital Anxiety and Depression Scale (HADS), Chalder Fatigue Questionnaire (CFQ), and Insomnia Severity Index (ISI), respectively, using an online survey system.

RESULTS

From the patient lists of six GPs, we included 969 patients. Mean age 46 years (SD: 10.1), and 517 reported CMP. CMP patients reported higher mean symptom score for anxiety (5.4 vs 3.7), depression (3.4 vs 2.0), fatigue (14.2 vs 11.2), and insomnia (8.1 vs 4.4), all p < 0.01 compared to no-CMP patients. Symptoms of impaired mental health increased with increasing number of pain sites and pain intensity (p < 0.001).

CONCLUSIONS

Primary health care patients with CMP reported significantly more symptoms of anxiety, depression, fatigue, and insomnia than patients without CMP. The higher number of pain sites and pain intensity, the more mental health symptoms, especially of anxiety. Primary health care personnel have to address mental health issues when treating patients with CMP.

The relationship between the Keele STarT back screening tool, the short form of central sensitivity inventory and health-related quality of life in patients with low back pain

INTRODUCTION

It has been reported that the scores of the Keele STarT Back Screening Tool (SBST) and the short form of Central Sensitization Inventory (CSI-9) are associated with Health-Related Quality of Life (HRQoL) in patients with low back pain (LBP). However, it is unclear which screening tool is more associated with HRQoL in patients with LBP.

OBJECTIVE

To identify which SBST and CSI-9 are more related to HRQoL and investigate the association between SBST and CSI-9 scores.

STUDY DESIGN

Cross-sectional study.

METHOD

A multiple regression analysis was conducted to examine the factors associated with the HRQoL using age, pain intensity, disability, SBST score, and CSI-9 score as independent variables. Spearman's rank correlation coefficient was also conducted to determine the association between SBST and CSI-9 score.

RESULTS

Multiple regression analysis revealed that the Oswestry Disability Index (ODI) score (p < 0.01, β = -0.62, VIF = 1.70) and SBST score (p < 0.01, β = -0.32, VIF = 1.86) were significant associated variables. A significant association was found between SBST and CSI-9 scores (p < 0.01, ρ = 0.47).

CONCLUSION

The results showed that in patients with LBP the association of HRQoL with SBST was more substantial than with CSI-9.

Prognostic Factors for Quality of Life After Interdisciplinary Pain Rehabilitation in Patients with Chronic Pain-A Systematic Review

BACKGROUND

Health-related quality of life (hrQoL) is a core outcome in evaluating interdisciplinary pain rehabilitation (IPR). This systematic review aimed to identify prognostic factors for hrQoL at least six months after IPR in chronic pain patients.

METHODS

A systematic search was conducted in MEDLINE, PsycINFO, EMBASE, CINAHL, Web of Science and Cochrane CENTRAL until September 2020. Included were prognostic studies on the outcome hrQoL in adults aged 18 to 67 years with chronic pain (excluding malignancies, systemic-, inflammatory or degenerative joint diseases) who had undergone IPR. Studies were assessed with The Quality in Prognostic Studies-tool. Potential prognostic factors at baseline for the domains pain, psychological and physical functioning were qualitatively synthesized for hrQoL. Grading of Recommendations Assessment, Development and Evaluation was used to evaluate the level of evidence.

RESULTS

Fourteen studies on 6,668 participants (mean age 37.4-52.8 y), with musculoskeletal pain/fibromyalgia and a pain duration ranging between 13.1 and 177.4 months were considered eligible. With a very low certainty of evidence, pain intensity, emotional distress, and physical functioning at baseline were inconsistent for prediction of hrQoL and pain duration was not predictive. With low certainty of evidence, fewer pain sites, lower levels of negative cognitive behavioral factors, and higher levels of positive cognitive behavioral factors predicted a better outcome.

CONCLUSIONS

The overall certainty of evidence was low to very low, making it difficult to reach definitive conclusions at present. Future studies with a predefined core set of predictors investigating hrQoL in patients with chronic pain after IPR are needed.

Depression and work productivity: insights from a longitudinal cohort study on digital care programs for Musculoskeletal conditions

BACKGROUND

Comorbidity between musculoskeletal (MSK) pain and depression is highly common and associated with greater symptom burden and greater loss of work productivity. Multimodal care programs tackling both physical and mental health components may maximize productivity recovery and return to work. Digital delivery of such programs can facilitate access, ensure continuity of care, and enhance patient engagement.

OBJECTIVE

Assess the impact of a completely remote multimodal digital care program (DCP) for MSK pain on mental health and work-related outcomes stratified by baseline depression levels.

METHODS

The present study is an ad-hoc analysis of an interventional, single-arm, cohort study of individuals with MSK pain undergoing a DCP. Three subgroups with different baseline depression severity levels were created based on the Patient Health Questionnaire (PHQ-9): cluster 1 (<5: minimal depression); cluster 2 (5-10: mild depression) and cluster 3 (≥10: moderate depression). The mean change between baseline and end-of-program (8-12 weeks) on depression, anxiety, fear-avoidance beliefs, work productivity and activity impairment and adherence was assessed across subgroups. Outcome changes were analyzed by latent growth curve analysis.

RESULTS

From a total of 7785 eligible participants, 6137 (78.8%) were included in Cluster 1, 1158 (14.9%) in cluster 2 and 490 (6.3%) in cluster 3. Significant improvements in depression and anxiety scores were observed in clusters 2 and 3 but not cluster 1, with average end-of-the program scores in clusters 2 and 3 below the initially defined cluster thresholds (5 and 10 for clusters 2 and 3, respectively). All clusters reported significant improvements in productivity impairment scores (mean changes from -16.82, 95%CI -20.32 to -13.42 in cluster 1 to -20.10, 95%CI -32.64 to -7.57 in cluster 3). Higher adherence was associated with higher improvements in depression in clusters 2 and 3, and with greater recovery in activities of daily living in cluster 3. Overall patient satisfaction was 8.59/10.0 (SD 1.74).

CONCLUSIONS

A multimodal DCP was able to promote improvements in productivity impairment scores comparable to those previously reported in the literature, even in participants with comorbid depression and anxiety. These results reinforce the need to follow a biopsychosocial framework to optimize outcomes in patients with MSK pain.

Health-related quality of life in patients with chronic orofacial pain compared with other chronic pain patients

Background

Health‐related quality of life (HRQoL) of orofacial pain patients is lower than that of the general population and impaired in multiple dimensions. The aim of the present study was to investigate HRQoL of orofacial pain patients in comparison with patients suffering from other chronic pain disorders.

Materials and Methods

One hundred and fifty‐one tertiary care facial pain patients (mean age, 50 years; standard deviation [SD], 15; 119 females), were compared with 312 other non‐cancer chronic pain patients (mean age, 46 years; SD, 13; 204 women), recruited from three multidisciplinary pain clinics in Finland. The groups were compared using the 15D, and pain‐related measures such as pain interference, pain acceptance, anxiety, depression, and sleep. Statistical comparisons between groups were done using t test, χ² test, or analysis of covariance. Multivariate linear regression analysis was used to study whether pain‐related aspects influencing HRQoL are similar between the patient groups.

Results

The 15D score was significantly higher in facial pain patients (0.823; SD, 0.114) indicating better HRQoL in comparison with other chronic pain patients (0.732; SD, 0.107) (p < .001). The 15D profiles of studied populations resembled each other but orofacial pain patients showed significantly higher scores for most individual 15D dimensions. Dimensions regarding discomfort and symptoms and sleep were most affected in both groups. Orofacial pain patients showed less psychosocial disability and better acceptance of their pain. Pain acceptance was a weaker explanatory factor of HRQoL in orofacial pain patients.

Conclusion

Compared to other non‐cancer chronic pain, chronic pain in the orofacial area causes less impairment in HRQoL. Orofacial pain patients showed less psychosocial disability and better pain acceptance.

[Kinesiophobia in patients requiring hip and knee endoprosthetics: severity and provoking factors]

Kinesiophobia (KP), or an irrational fear of physical activity, significantly hinders the active rehabilitation of patients with joint pathology.

PURPOSE OF THE STUDY

To study the severity and risk factors of KP in patients requiring total hip and knee endoprosthetics (EP).

MATERIAL AND METHODS

We examined 50 patients requiring total EP of the hip and knee joints. Pain syndrome was assessed in the preoperative and early postoperative periods in all patients using a visual analog scale, as well as the levels of kinesiophobia, anxiety, and depression using the Hospital Anxiety and Depression Scale and the Tampa Scale for Kinesiophobia (TSK). Quality of patients life was studied in the preoperative period (RAND SF36 questionnaire).

RESULTS

In the majority of cases, both before and after EP, the level of KP corresponded to an average degree of severity. Both in the preoperative and in the early postoperative periods, not a single case of the absence of KP was detected (≤17 points according to the TSK); at the same time, a very high level of KP (≥55 points according to TSK) was also rarely recorded - in 3 patients in the postoperative period after EP of the hip joint. KP level significantly correlated with the duration of the pain syndrome, while the mental component of the KP, in addition to the duration of the pain syndrome, was influenced by the social status: in patients who had a steady job, the psychological component of the KP was expressed in a less degree. KP level was negatively correlated with such indicators of quality of life as vitality and physical functioning. In addition, the physical component of the KP significantly correlated with the pain intensity, the mental component - with role-playing behavior.

CONCLUSION

Early detection of KP and timely correction of distorted ideas about physical activity are necessary for successful rehabilitation of patients requiring total joint endoprosthetics of the lower limb.

Multiple Factors Affecting Health-Related Quality of Life in Women With Chronic Multisite Musculoskeletal Pain: A Cross-Sectional Study in Ankara, Turkey

Although chronic multi-site musculoskeletal pain is known to cause decreased physical function and impair work and social life, there is insufficient research about its impact on health-related quality of life (HRQoL) in women. The aim of this study was to investigate multiple factors affecting HRQoL in women with chronic multi-site musculoskeletal pain. This study included 227 women with two or more musculoskeletal areas which were painful during the last 3 months. The HRQoL and musculoskeletal system symptoms were evaluated with the Nottingham Health Profile (NHP) and the Nordic Musculoskeletal Questionnaire (NMQ), respectively. Physical activity level, social functionality and depressive symptoms were assessed with the International Physical Activity Questionnaire-Short Form (IPAQ- SF), Social Functioning Scale (SFS) and Beck Depression Inventory (BDI), respectively. Significant predictors for the total score on the NHP were found to be the number of children (p < 0.001), social engagement/withdrawal scale (p:0.094), the number of regions with musculoskeletal pain during the last year (p:0.002) and last 7 days (p:0.036), depressive symptoms (p < 0.001), current employment status (p:0.084), and the presence of chronic disease (p < 0.001). The results of this study demonstrated that both sociodemographic characteristics, and social and psychological factors may affect the HRQoL in women with chronic multi-site musculoskeletal pain.

What factors are associated with health-related quality of life among patients with chronic musculoskeletal pain? A cross-sectional study in primary health care

BACKGROUND

Chronic musculoskeletal pain (CMP) affects daily life function and is the most prevalent disorder in primary health care. The primary objective was to examine demographic factors and pain characteristics associated with reduced health-related quality of life (HRQoL) among patients in primary care reporting CMP. Our secondary objective was to compare HRQoL in patients with and without CMP.

METHOD

This cross-sectional study was conducted in Trondheim, Norway. Twenty randomly selected GPs, and their listed patients aged 21-58 were invited to participate. Self-reported CMP data was collected using online questionnaires. HRQoL was measured by the 15D questionnaire, total score of 0.9 was used as cut-off for clinical reduced HRQoL.

RESULTS

A total of 969 patients (650 females) were recruited from six GPs' patient lists, mean age 45.6 (SD 10.1). CMP was reported by 517 (53%). Factors significantly associated with reduced HRQoL were gender (OR 2.0, 95% CI 1.2, 3.4), disability pension (OR 26.6, 95% CI 3.1, 228.0), mood (OR 1.3, 95% CI 1.1, 1.6), relations with other people (OR 0.8, 95% CI 0.6, 0.9), sleep (OR 1.2, 95% CI 1.0, 1.3) and enjoyment (OR 1.2, 95% CI 1.0). CMP patients had significantly lower total HRQoL score compared to patients without CMP (Between group difference 0.08, 95% CI 0.07-0.09). Half of the CMP patients reported a HRQoL score < 0.9 compared to 14% in the no CMP group.

CONCLUSIONS

Being female, receiving disability pension, and several psychosocial factors were found highly associated with reduced HRQoL in CMP patients, whereas pain characteristics were not. Patients with CMP reported statistically and clinically significant lower HRQoL than patients without CMP. Due to low response rate the conclusions must be handled with caution.

Health-related quality of life and its determinants in patients with chronic low back pain at a tertiary hospital in Cameroon: a cross-sectional study

OBJECTIVE

To evaluate health-related quality of life (HRQoL) and its determinants in chronic low back pain (CLBP) patients in Cameroon.

DESIGN

Observational cross-sectional study.

SETTING

Tertiary hospital.

PARTICIPANTS

There were 150 eligible adults with low back pain of at least 12 weeks who provided informed consent. Of these, 136 with complete questionnaires were analysed.

OUTCOMES

HRQoL was measured using the WHO Quality of Life questionnaire (WHOQOL-BREF). Outcome measures included its four domain (physical health, psychological, social relationships and environmental) scores and two independent scores for overall quality of life (OQOL) and general health satisfaction (GH).

RESULTS

Participants had a median age of 52 years, and median pain duration of 33 (IQR: 69) months. The median OQOL score was 50 (IQR: 25). After multivariable adjustment, tertiary education (β=11.43, 95% CI 3.12 to 19.75), age (β=0.49, 95% CI 0.12 to 0.87) and being a student (β=23.07, 95% CI 0.28 to 45.86) contributed to better OQOL. Age (β=0.57, 95% CI 0.10 to 1.04) and physical-type employment (β=-14.57, 95% CI -25.83 to -3.31) affected GH. Smoking (β=-20.49, 95% CI -35.49 to -5.48) and radiological anomalies (β=-7.57, 95% CI -14.64 to -0.49) affected the physical health domain, while disability (β=-0.67, 95% CI -1.14 to -0.20) and duration of pain (β=-0.13, 95% CI -0.20 to -0.05) affected the psychological domain. Income (β=14.94, 95% CI 4.06 to 25.81) affected the social domain, while education (β=9.96, 95% CI 1.41 to 18.50) and disability (β=-0.75, 95% CI -1.26 to -0.24) affected the environmental domain.

CONCLUSIONS

Our findings suggest that CLBP affects HRQoL and multiple socioeconomic and clinical factors influence its impact on different domains of HRQoL. Multipronged management programmes, especially those that reduce disability, could improve HRQoL in patients with CLBP.

Quality of life among district hospital nurses with multisite musculoskeletal symptoms in Vietnam

Background

Nurses are one of the population groups with the highest prevalence of musculoskeletal disorders (MSDs). At many sites, musculoskeletal symptoms (MS) represent a major health‐care burden, adversely affecting nurses' quality of life and giving rise to mental health issues.

Objectives

This study measured the prevalence of multi‐body‐site (two or more anatomical sites) musculoskeletal symptoms (MMS), and the association between MMS, a number of demographic and work characteristics, psychological distress, and the quality of life among district hospital nurses.

Material and Methods

A cross‐sectional study was performed with 1179 nurses in Haiphong City using three questionnaires: the Modified Nordic; Quality of Life Enjoyment and Satisfaction Short Form (Q‐LES‐Q‐SF); and the Kessler Psychological Distress Questionnaire (K6).

Results

Women have a higher MMS prevalence than men (57.1% in women vs 37.6% in men, P < .001). Having a higher number of anatomical sites of MS appears to be associated with a worse quality of life among nurses. Linear regression analysis found a number of other factors negatively associated with the nurses' quality of life: gender (female), age (50‐60 years old vs 19‐29 years old), and psychological distress.

Conclusions

This study shows a high prevalence of MMS and the relationship between, on the one hand, MMS, gender, age, as well as psychological distress and, on the other hand, the quality of life among nurses in Vietnam. Further in‐depth studies are needed to investigate the causal relationships between these indicators.

Chronic Pain Patients' Kinesiophobia and Catastrophizing are Associated with Activity Intensity at Different Times of the Day

Purpose

To examine the relationship between baseline kinesiophobia and baseline pain catastrophizing with the 4-day average activity intensity at different times of the day while accounting for different wake and sleep-onset times in chronic pain patients.

Methods

Twenty-one participants suffering from idiopathic chronic pain completed baseline questionnaires about kinesiophobia, catastrophizing, disability, depression, and pain. We measured the participants' activity using accelerometers and calculated activity intensity in the morning, afternoon, and evening. We performed a 2-way repeated measures ANOVA to compare activity levels at different times of the day, and multiple linear regressions.

Results

Baseline kinesiophobia was significantly associated with 4-day average evening light activity and sedentary activity at all time periods while baseline catastrophizing was significantly associated with increased 4-day average light activity in the evening and more moderate to vigorous activity in the morning. Our participants engaged in more light activity on average than sedentary activity, and very little moderate-vigorous activity. Participants were most active in the afternoon.

Conclusion

Baseline kinesiophobia and baseline catastrophizing were not associated with the 4-day average total daily activity; however, they were associated with 4-day average activity intensities at different times throughout the day. Segmenting daily activity into morning, afternoon, evening may influence the relationship between daily activity, and kinesiophobia and pain catastrophizing. Individuals with chronic pain are less sedentary than previously thought which may affect future interventions.

Mechanism-based pain management in chronic pancreatitis - is it time for a paradigm shift?

INTRODUCTION

Pain is the most common symptom in chronic pancreatitis and treatment remains a challenge. Management of visceral pain, in general, is only sparsely documented, and treatment in the clinic is typically based on empirical knowledge from somatic pain conditions. This may be problematic, as many aspects of the neurobiology differ significantly from somatic pain, and organs such as the gut and liver play a major role in tolerability to analgesics. On the other hand, clinical awareness and new methods for quantitative assessment of pain mechanisms, will likely increase our understanding of the visceral pain system and guide more individualized pain management. Areas covered: This review includes an overview of known pain mechanisms in chronic pancreatitis and how to characterize them using quantitative sensory testing. The aim is to provide a mechanism-oriented approach to analgesic treatment, including treatment of psychological factors affecting pain perception and consideration of side effects in the management plan. Expert opinion: A mechanism-based examination and profiling of pain in chronic pancreatitis will enable investigators to provide a well-substantiated approach to effective management. This mechanism-based, individualized regime will pave the road to better pain relief and spare the patient from unnecessary trial-and-error approaches and unwanted side effects.

People with musculoskeletal shoulder pain demonstrate no signs of altered pain processing

BACKGROUND

Central sensitisation may contribute to persistent musculoskeletal shoulder pain. Few studies have provided a comprehensive sensory and psychosocial evaluation of this population.

OBJECTIVE

To comprehensively assess whether sensory function and psychosocial aspects are impaired in people with shoulder pain and whether age, gender and clinical outcomes are related to impaired sensory function.

STUDY DESIGN

Observational case-control study.

METHODS

Twenty-three participants with musculoskeletal shoulder pain and 23 age- and gender-matched healthy participants were included. Static (pressure and thermal pain thresholds) and dynamic (temporal summation) quantitative sensory testing was performed bilaterally at the shoulder and remote tibialis anterior muscle. Conditioned pain modulation was measured at the affected/matched shoulder. Shoulder function (SPADI), depression, anxiety and stress (DASS-21) and health-related quality of life (EQ-5D-5L) were also measured. Comparisons were performed between body regions and groups. Age and gender were included as factors in analyses. Clinical outcomes were tested for correlation with sensory measures.

RESULTS

Shoulder pain group had higher local pressure pain threshold (i.e., hypoalgesia; p = 0.03; Z = 0-5.04), higher SPADI score (p < 0.01; Z = -5.76) and higher EQ-5D-5L (p < 0.01; Z = 5.23) compared to the control group. There was no difference between groups for thermal pain sensitivity, dynamic sensory testing or psychological measures.

CONCLUSION

People with shoulder pain demonstrated mechanical hypoalgesia, increased upper limb disability and poorer quality of life compared with healthy controls. Central sensitisation seems not be a characteristic of musculoskeletal shoulder pain although it could be present in a subgroup of patients.

How does exercise dose affect patients with long-term osteoarthritis of the knee? A study protocol of a randomised controlled trial in Sweden and Norway: the SWENOR Study

INTRODUCTION

Osteoarthritis (OA) of the knee is characterised by knee pain, disability and degenerative changes, and places a burden on societies all over the world. Exercise therapy is an often-used modality, but there is little evidence of what type of exercise dose is the most effective, indicating a need for controlled studies of the effect of different dosages. Thus, the aim of the study described in this protocol is to evaluate the effects of high-dose versus low-dose medical exercise therapy (MET) in patients with knee OA.

METHODS AND ANALYSIS

This is a multicentre prospective randomised two-arm trial with blinded assessment and data analysis. We are planning to include 200 patients aged 45-85 years with symptomatic (pain and decreased functioning) and X-ray verified diagnosis of knee OA. Those eligible for participation will be randomly allocated to either high-dose (n=100) or low-dose (n=100) MET. All patients receive three supervised treatments each week for 12 weeks, giving a total of 36 MET sessions. The high-dose group exercises for 70-90 min compared with 20-30 min for the low-dose group. The high-dose group exercises for a longer time, and receives a greater number of exercises with more repetitions and sets. Background and outcome variables are recorded at inclusion, and outcome measures are collected after every sixth treatment, at the end of treatment, and at 6-month and 12-month follow-ups. Primary outcome is self-rated knee functioning and pain using the Knee Injury and Osteoarthritis Outcome Score (KOOS). The primary end point is at the end of treatment after 3 months, and secondary end points are at 6 months and 12 months after the end of treatment.

ETHICS AND DISSEMINATION

This project has been approved by the Regional Research Ethics Committees in Stockholm, Sweden, and in Norway. Our results will be submitted to peer-reviewed journals and presented at national and international conferences.

Role of kinesiophobia on pain, disability and quality of life in people suffering from chronic musculoskeletal pain: a systematic review

Objective

(1) To explore the level of association between kinesiophobia and pain, disability and quality of life in people with chronic musculoskeletal pain (CMP) detected via cross-sectional analysis and (2) to analyse the prognostic value of kinesiophobia on pain, disability and quality of life in this population detected via longitudinal analyses.

Design

A systematic review of the literature including an appraisal of the risk of bias using the adapted Newcastle Ottawa Scale. A synthesis of the evidence was carried out.

Data sources

An electronic search of PubMed, AMED, CINAHL, PsycINFO, PubPsych and grey literature was undertaken from inception to July 2017.

Eligibility criteria for selecting studies

Observational studies exploring the role of kinesiophobia (measured with the Tampa Scale for Kinesiophobia) on pain, disability and quality of life in people with CMP.

Results

Sixty-three articles (mostly cross-sectional) (total sample=10 726) were included. We found strong evidence for an association between a greater degree of kinesiophobia and greater levels of pain intensity and disability and moderate evidence between a greater degree of kinesiophobia and higher levels of pain severity and low quality of life. A greater degree of kinesiophobia predicts the progression of disability overtime, with moderate evidence. A greater degree of kinesiophobia also predicts greater levels of pain severity and low levels of quality of life at 6 months, but with limited evidence. Kinesiophobia does not predict changes in pain intensity.

Summary/conclusions

The results of this review encourage clinicians to consider kinesiophobia in their preliminary assessment. More longitudinal studies are needed, as most of the included studies were cross-sectional in nature.

Symptoms of anxiety and depression are related to cardiovascular responses to active, but not passive, coping tasks

Objective:

Anxiety and depression have been linked to blunted blood pressure (BP) and heart rate (HR) reactions to mental stress tests; however, most studies have not included indices of underlying hemodynamics nor multiple stress tasks. This study sought to examine the relationships of anxiety and depression with hemodynamic responses to acute active and passive coping tasks.

Methods:

A total of 104 participants completed the Hospital Anxiety and Depression Scales and mental arithmetic, speech, and cold pressor tasks while BP, HR, total peripheral resistance, and cardiac output (CO) were assessed.

Results:

After adjustment for traditional risk factors and baseline cardiovascular activity, depression scores were negatively associated with systolic BP, HR, and CO responses to the mental arithmetic task, while anxiety scores were inversely related to the systolic BP response to mental arithmetic.

Conclusion:

High anxiety or depression scores appear to be associated with blunted cardiac reactions to mental arithmetic (an active coping task), but not to the cold pressor test or speech tasks. Future research should further examine potential mechanisms and longitudinal pathways relating depression and anxiety to cardiovascular reactivity.

The Role of Health Locus of Control in Evaluating Depression and Other Comorbidities in Patients with Chronic Pain Conditions, A Cross-Sectional Study

OBJECTIVE

Chronic pain is significantly influenced by behavioral, cognitive, and emotional factors. Few studies have investigated the health locus of control (HLC)-one's belief regarding where control over one's health lies-as it relates to patients with chronic pain. The purpose of this prospective, cross-sectional study was to examine the relationship between depression and health/pain locus of control (HLC) in adult patients with persistent pain.

MATERIAL AND METHODS

A series of questionnaires was administered to chronic pain patients, and these questionnaires were scored and analyzed. Patients were categorized into 3 groups based on health locus of control (internal, chance, powerful-others), which were examined with respect to their depression scores using analysis of variance.

RESULTS

A total of 131 patients completed the study: 33% belonged to the internal group, 39% in the chance group, and 28% in the powerful-others group. The 3 groups had depression scores of 40 (SD = 8), 47 (SD = 10), and 42 (SD = 8), respectively. We found significant difference in depressions scores between the chance group and the internal group (P < 0.005) with the chance group having higher depression scores compared to the internal group.

CONCLUSIONS

The study shows that patients with an internal locus of control are less depressed compared to patients with fatalistic views on their health/pain in the chance group. The chance dimension of the Multidimensional Health Locus of Control scale was found to be a potential predictor of psychiatric comorbidities such as depression in the chronic pain patient population.

Chronic stress, cortisol dysfunction, and pain: a psychoneuroendocrine rationale for stress management in pain rehabilitation

Pain is a primary symptom driving patients to seek physical therapy, and its attenuation commonly defines a successful outcome. A large body of evidence is dedicated to elucidating the relationship between chronic stress and pain; however, stress is rarely addressed in pain rehabilitation. A physiologic stress response may be evoked by fear or perceived threat to safety, status, or well-being and elicits the secretion of sympathetic catecholamines (epinephrine and norepinepherine) and neuroendocrine hormones (cortisol) to promote survival and motivate success. Cortisol is a potent anti-inflammatory that functions to mobilize glucose reserves for energy and modulate inflammation. Cortisol also may facilitate the consolidation of fear-based memories for future survival and avoidance of danger. Although short-term stress may be adaptive, maladaptive responses (eg, magnification, rumination, helplessness) to pain or non-pain-related stressors may intensify cortisol secretion and condition a sensitized physiologic stress response that is readily recruited. Ultimately, a prolonged or exaggerated stress response may perpetuate cortisol dysfunction, widespread inflammation, and pain. Stress may be unavoidable in life, and challenges are inherent to success; however, humans have the capability to modify what they perceive as stressful and how they respond to it. Exaggerated psychological responses (eg, catastrophizing) following maladaptive cognitive appraisals of potential stressors as threatening may exacerbate cortisol secretion and facilitate the consolidation of fear-based memories of pain or non-pain-related stressors; however, coping, cognitive reappraisal, or confrontation of stressors may minimize cortisol secretion and prevent chronic, recurrent pain. Given the parallel mechanisms underlying the physiologic effects of a maladaptive response to pain and non-pain-related stressors, physical therapists should consider screening for non-pain-related stress to facilitate treatment, prevent chronic disability, and improve quality of life.

Hypnotherapy for disability-related pain: A meta-analysis

Hypnotherapy can address the biopsychosocial aspects of disability-related pain, although the available evidence is limited in quality and quantity. Meta-analytic techniques were utilised to evaluate 10 controlled studies. Hypnotherapy produced significant short-term improvements in fatigue, pain experience and affect. However, a lack of significance was noted at 3- to 6-month follow-up. A beneficial effect size (d(w)= 0.53; confidence interval = 0.28-0.84) in comparison to control conditions was reported, although comparability with other cognitive-behavioural treatments could not be confirmed across the few studies reporting this data (d(w)= 0.06; confidence interval = -0.33 to 0.45). The findings highlight the need for further controlled and longitudinal research in this area.

Variables associated with patient activation in persons with multiple sclerosis

Identifying variables associated with patient activation in the multiple sclerosis population could serve to facilitate better multiple sclerosis self-management behaviors. Using a cross-sectional survey design, 199 participants were recruited from a multiple sclerosis center in the Southeastern United States. Depression, multiple sclerosis quality of life, and multiple Sclerosis self-efficacy were all significantly correlated with patient activation. Results of a hierarchical regression indicated that patient activation was significantly related to educational attainment, depression, and self-efficacy but not to quality of life. The results suggest several possible targets for intervention to increase patient activation, including health literacy, depression symptoms, and self-efficacy for multiple sclerosis disease management.

Trajectory of change in pain, depression, and physical functioning after physical activity adoption in fibromyalgia

Fibromyalgia is associated with widespread pain, depression, and declines in physical functioning. The purpose of this study was to examine the trajectory of these symptoms over time related to physical activity adoption and maintenance via motivational interviewing versus education, to increase physical activity. There were no treatment group differences; we divided the sample ( n = 184) based on changes in physical activity. Repeated measures analyses demonstrated differential patterns in depression, pain, and physical functioning at 24 and 36 weeks. Findings suggest increased physical activity may serve as a multiple-target intervention that provides moderate to large, long-lasting benefits for individuals with fibromyalgia.

Age and the role of restricted activities in adjustment to disability-related pain

Chronic pain is common in individuals with multiple sclerosis and spinal cord injury and is associated with depressed mood. This may be because pain creates interference in performing and enjoying valued activities. The importance of pain interference may also vary with age, since older adults may have lowered expectations regarding function. This study analyzed relationships among pain variables, age, and mood in 521 individuals with multiple sclerosis or spinal cord injury. As predicted, pain interference mediated the relationship between pain severity and depressed mood. There was no evidence that older adults were less distressed by pain interference than were younger adults.

Gender differences in perception of quality of life in adults with and without chronic health conditions: the role of depressive symptoms

Previous studies have shown that chronic conditions have a negative impact on quality of life. Furthermore, this impact appears to be different in males and females, but it is not yet clear what factors may mediate this relationship. Females with chronic health conditions had poorer quality of life in the physical and psychological domains as compared to males with chronic health conditions. The difference between male and female patients in the psychological domain disappeared when the analysis was adjusted for confounding factors such as age, presence of a chronic health condition, socioeconomic status, and depressive symptoms.
