Daily pain catastrophizing predicts less physical activity and more sedentary behavior in older adults with osteoarthritis

Determinants of sedentary behavior in community-dwelling older adults with type 2 diabetes based on the behavioral change wheel: a path analysis

BACKGROUND

Sedentary behavior (SB) is deeply ingrained in the daily lives of community-dwelling older adults with type 2 diabetes mellitus (T2DM). However, the specific underlying mechanisms of the determinants associated with SB remain elusive. We aimed to explore the determinants of SB based on the behavior change wheel framework as well as a literature review.

METHODS

This cross-sectional study recruited 489 community-dwelling older adults with T2DM in Jinan City, Shandong Province, China. Convenience sampling was used to select participants from relevant communities. This study used the Measure of Older Adults' Sedentary Time-T2DM, the Abbreviated-Neighborhood Environment Walkability Scale, the Social Support Rating Scale, the Lubben Social Network Scale 6, the Subjective Social Norms Questionnaire for Sedentary Behavior, the Functional Activities Questionnaire, the Numerical Rating Scale, the Short Physical Performance Battery, and the Montreal Cognitive Assessment Text to assess the levels of and the determinants of SB. Descriptive statistical analysis and path analysis were conducted to analyze and interpret the data.

RESULTS

Pain, cognitive function, social isolation, and social support had direct and indirect effects on SB in community-dwelling older adults with T2DM (total effects: β = 0.426, β = -0.171, β = -0.209, and β = -0.128, respectively), and physical function, walking environment, and social function had direct effects on patients' SB (total effects: β = -0.180, β = -0.163, and β = 0.127, respectively). All the above pathways were statistically significant (P < 0.05). The path analysis showed that the model had acceptable fit indices: RMSEA = 0.014, χ 2/df = 1.100, GFI = 0.999, AGFI = 0.980, NFI = 0.997, RFI = 0.954, IFI = 1.000, TLI = 0.996, CFI = 1.000.

CONCLUSION

Capability (physical function, pain, and cognitive function), opportunity (social isolation, walking environment, and social support), and motivation (social function) were effective predictors of SB in community-dwelling older adults with T2DM. Deeper knowledge regarding these associations may help healthcare providers design targeted intervention strategies to decrease levels of SB in this specific population.

Pain catastrophizing in rheumatic diseases: prevalence, origin, and implications

Pain is a crucial factor in rheumatic disorders, and reducing it is a primary goal of successful treatment. Adaptive pain-coping strategies can enhance this improvement, but maladaptive approaches such as pain catastrophizing may worsen overall patient well-being. This narrative review aims to provide a concise overview of the existing knowledge on pain catastrophizing in the most prevalent specific rheumatic disorders. The objective of this study was to improve understanding of this phenomenon and its implications, as well as to pinpoint potential directions for future research. We conducted searches in the MEDLINE/PubMed, SCOPUS, and DOAJ bibliography databases to identify articles related to pain catastrophizing in rheumatoid arthritis, psoriatic arthritis, axial spondylarthritis, systemic sclerosis, systemic lupus erythematosus, Sjögren's syndrome, juvenile idiopathic arthritis, and osteoarthritis (non-surgical treatment). Data extraction was performed on November 1, 2023. The investigators screened the identified articles to determine their relevance and whether they met the inclusion criteria. Following a bibliography search, which was further expanded by screening of citations and references, we included 156 records in the current review. The full-text analysis centred on pain catastrophizing, encompassing its prevalence, pathogenesis, and impact. The review established the role of catastrophizing in amplifying pain and diminishing various aspects of general well-being. Also, potential treatment approaches were discussed and summarised across the examined disorders. Pain catastrophizing is as a significant factor in rheumatic disorders. Its impact warrants further exploration through prospective controlled trials to enhance global patient outcomes.

Associations of pain sensitivity and conditioned pain modulation with physical activity: findings from the Multicenter Osteoarthritis Study (MOST)

OBJECTIVE

Individuals with chronic pain due to knee osteoarthritis (OA) are insufficiently physically active, and alterations of facilitatory and inhibitory nociceptive signaling are common in this population. Our objective was to examine the association of these alterations in nociceptive signaling with objective accelerometer-based measures of physical activity in a large observational cohort.

DESIGN

We used data from the Multicenter Osteoarthritis Study. Measures of peripheral and central pain sensitivity included pressure pain threshold at the knee and mechanical temporal summation at the wrist, respectively. The presence of descending pain inhibition was assessed by conditioned pain modulation (CPM). Physical activity was quantitatively assessed over 7 days using a lower back-worn activity monitor. Summary metrics included steps/day, activity intensity, and sedentary time. Linear regression analyses were used to evaluate the association of pain sensitivity and the presence of descending pain inhibition with physical activity measures.

RESULTS

Data from 1873 participants was analyzed (55.9% female, age = 62.8 ± 10.0 years). People having greater peripheral and central sensitivity showed lower step counts. CPM was not significantly related to any of the physical activity measures, and none of the exposures were significantly related to sedentary time.

CONCLUSIONS

In this cohort, greater peripheral and central sensitivity were associated with reduced levels of objectively-assessed daily step counts. Further research may investigate ways to modify or treat heightened pain sensitivity as a means to increase physical activity in older adults with knee OA.

A Mind-Body Intervention to Improve Physical Activity for Patients with Chronic Hip-Related Pain: Protocol for a Mixed Methods Study

BACKGROUND

Pain and dysfunction persist for most patients following hip-related pain treatment. Additionally, individuals with hip-related pain are typically less physically active than individuals without hip pain, despite evidence that regular physical activity reduces chronic musculoskeletal pain. Poor psychological health is common in patients with hip-related pain and further reinforces low physical activity. Mind-body interventions can improve psychological health and activity levels but have yet to be integrated to provide comprehensive, psychologically informed care for patients with hip-related pain. Thus, we are using the NCCIH intervention development framework to develop Helping Improve PSychological Health (HIPS), a novel, multimodal mind-body intervention to improve physical activity for individuals with hip-related pain and poor psychological health.

METHODS

We will recruit physical therapists (N = 20) and patients with hip-related pain (N = 20) to participate in 60 min qualitative interviews (focus groups with therapists; one-on-one interviews with patients). Using these data, we will develop the initial HIPS intervention and provider training materials. One physical therapist will be trained to deliver the HIPS intervention to five participants in an open pilot trial. Participants will attend six 30 min HIPS intervention sessions. We will collect quantitative data on satisfaction, improvement, and physical activity, alongside qualitative exit interviews with participants and the physical therapist in order to refine the HIPS intervention and provider training materials.

RESULTS

This study has been approved by the MGB IRB. We aim to develop and test the initial feasibility of the HIPS intervention in an open pilot trial. The findings from this project will inform a subsequent feasibility RCT.

Chain-mediating effects of kinesiophobia and self-efficacy on pain catastrophizing and physical activity in haemophilia patients

BACKGROUND

There is a lack of research on the relationship between pain catastrophizing, kinesiophobia, and physical activity (PA) in people with haemophilia (PWH), and the underlying mechanisms connecting these variables remain unclear.

AIM

The study's aim was to clarify the roles of kinesiophobia and self-efficacy in the relationship between pain catastrophizing and PA in PWH.

METHODS

This cross-sectional study included adult PWH at the Haemophilia Centre of a Tertiary hospital in Beijing, China. The following questionnaires were used to collect data: the general information, the International Physical Activity Short Questionnaire, the Pain Catastrophizing Scale, the Tampa Scale of Kinesiophobia Scale, and the Exercise Self-Efficacy Scale.

RESULTS

The study included a total of 187 PWH, including 154 having haemophilia A and 33 having haemophilia B. The median interquartile range of PA was 594 (198, 1554) MET-min/wk. There were significant differences in PA of patients based on age stage, treatment modality, highest pain score within the last seven days, and presence of haemophilic arthropathy (p < .05). It was showed that pain catastrophizing could directly predict PA (p < .001), accounting for 38.13% of the total effect. Pain catastrophizing also had indirect effects on PA through the mediating factors of kinesiophobia or self-efficacy, and through the chain-mediating effect of kinesiophobia and self-efficacy, accounting for 38.40%, 17.07%, and 6.40%, respectively.

CONCLUSION

The study discovered that PWH have limited PA due to pain catastrophizing. This not only directly affects their activity but also indirectly influences it through kinesiophobia and self-efficacy.

Examining the Association Between Objective Physical Activity and Momentary Pain: A Systematic Review of Studies Using Ambulatory Assessment

Chronic pain (CP) is a debilitating and increasingly common health condition that adversely impacts function, including physical activity (PA). Research using ambulatory assessment (AA) methods (eg, ecological momentary assessment, actigraphy) offers promise for elucidating the relationship between momentary pain and objective PA in CP populations. This study aimed to systematically review articles assessing the association between momentary pain and PA in adults with CP as measured using AA and to make recommendations for the measurement and study of this relationship. Five databases were systematically searched, and 13 unique records (N = 768) met the inclusion criteria. CP conditions included mixed/nonspecific CP (k = 3), low back pain (k = 2), fibromyalgia (k = 1), unspecified arthritis (k = 1), and hip/knee osteoarthritis (k = 6). The average age of participants across studies was 55.29 years, and the majority identified as women (60.68%) and White (83.16%). All studies measured objective PA via actigraphy, and momentary pain with either a diary/log or ratings on an actigraph. Studies varied in the quantification of PA (ie, activity counts, step count, moderate-vigorous PA), statistical method (ie, correlation, regression, multilevel modeling), and inclusion of moderators (eg, pain acceptance). Studies reported mixed results for the pain-PA relationship. This heterogeneity suggests that no summarizing conclusions can be drawn about the pain-PA relationship without further investigation into its complex nuances. More within-person and exploratory examinations that maximize the richness of AA data are needed. A greater understanding of this relationship can inform psychotherapeutic and behavioral recommendations to improve CP outcomes. PERSPECTIVE: This article presents a systematic review of the literature on the association between momentary pain and PA in adults with CP as measured using AA methods. A better understanding of this nuanced relationship could help elucidate areas for timely intervention and may inform clinical recommendations to improve CP outcomes.

Associations Between Patterns of Daily Stepping Behavior, Health-Related Quality of Life, and Pain Symptoms Among Older Adults with Chronic Pain: A Secondary Analysis of Two Randomized Controlled Trials

Purpose

One's amount, intensity, and distribution of physical activity may have implications for whether it has positive or negative effects on pain and quality of life for older adults living with chronic pain. Thus, we investigated baseline patterns of stepping related to pain symptoms and health-related quality of life at baseline and over a 12-week follow-up period.

Patients and Methods

Participants were low-active older adults (69.54±6.74 years) with obesity and chronic pain who enrolled in one of two randomized controlled trials. Participants completed measures of pain intensity, interference, and health-related quality of life and wore an accelerometer for 7 days at baseline and week 12. Functional principal components analysis identified patterns of within-day stepping behavior at baseline, and linear regressions were used to investigate how these component scores related to pain and health-related quality of life at baseline and over 12 weeks.

Results

Two patterns were extracted; one describing more vs less stepping and the second capturing movement later vs earlier in the day. More baseline stepping was associated with better physical functioning (B=0.148, p<0.001) and energy (B=0.073, p=0.033), while a later start in the day was associated with worse social functioning (B=-0.193, p=0.031). More stepping at baseline predicted positive changes in physical functioning (B=0.094, p=0.019), emotional role limitations (B=0.132, p=0.049), energy (B=0.112, p<0.001), social functioning (B=0.086, p=0.043), pain (B=0.086, p=0.009), general health (B=0.081, p=0.003) and pain intensity (B=-0.039, p=0.003). A later start to the day was associated with worsening physical functioning (B=-0.229, p<0.001), physical (B=-0.282, p=0.047) and emotional role limitations (B=-0.254, p=0.048), general health (B=-0.108, p=0.041), and pain interference (B=0.055, p=0.043).

Conclusion

Findings suggest there is value in activity patterns as an indicator for additional behavioral intervention, as those who move little and/or delay daily movement are likely to experience subsequent decrements in quality of life and pain symptoms.

Musculoskeletal Pain, Mood, and Sports Injury in Wheelchair Power Soccer Players

CONTEXT

Wheelchair Power Soccer (WPS) is the only team sport that allows the participation of people with severe physical disabilities who require the daily use of motorized wheelchairs. These individuals may live with chronic pain due to the characteristics of the disabilities and treatments, interfering with their health and limiting their participation in sports.

OBJECTIVES

To investigate the prevalence of musculoskeletal pain and its relationship with mood in WPS players and to analyze the incidence of traumatic injuries during a championship.

METHODS

A prospective, longitudinal study was carried out on 30 WPS athletes (93.33% male) with a mean (SD) (range) age of 22.37 (9.79) (47) years. Data collection was performed during a South American WPS Championship lasting 3 days, with: investigation of the presence of musculoskeletal pain and mood through a questionnaire; investigation of the occurrence of traumatic injuries through match observation; and confirmation of the occurrence of traumatic injuries through access to medical department records.

RESULTS

About 30% (n = 9/30) of the sample presented some pain on the day of evaluation, with an intensity of 5.67 (3.35) (10) points on the visual analog scale. The most common regions of pain were the lower back (13.3%, n = 4/30), thoracic (10%; n = 3/30), and cervical (10%; n = 3/30) areas of the spine. A total of 46.7% (n = 14/30) reported pain in the month before data collection but of less intensity (2.56 [4] [10] points), the most common regions being the lower limbs (20%; n = 6/30) and cervical spine (20%; n = 6/30). Among the between-group comparisons (ie, participants with pain vs without pain), no relationship was observed between mood state and pain. No traumatic injuries were identified during the competition.

CONCLUSION

The presence of musculoskeletal pain was common in WPS players, but it was not related to mood. As no traumatic injuries were observed during the championship, this modality seems to be safe for people with physical disabilities in general.

A Systematic Review of Physical Activity and Sedentary Behavior Patterns in an Osteoarthritic Population

OBJECTIVE

To explore physical activity (PA) and sedentary behaviors (SB) in individuals with lower limb (LL) Osteoarthritis (OA) and the influence of age, sex, and body mass index (BMI) on these behaviors.

DESIGN

Systematic review search: PubMed, Cochrane Library, ScienceDirect, and CINAHL databases were searched from inception until July 2023. Study criteria: Studies that reported quantifiable device-based or self-reported data for PA and SB variables in adults clinically diagnosed with LL OA were included.

DATA SYNTHESIS

A synthesis of PA and SB levels for those diagnosed with LL OA and the influence age, sex, and BMI have on these behaviors.

RESULTS

From the 1930 studies identified through the electronic search process, 48 met the inclusion criteria. PA guidelines were met by 33% of the sample population that measured moderate and moderate to vigorous PA. No studies reported 75 minutes per week or more of vigorous PA. Additionally, 58% of the population reporting SB were sedentary for 8 hours per day or more. Also, increasing age, BMI, and the female sex were identified as negative influences on PA levels. There were numerous methodological inconsistencies in how data were collected and reported, such as various activity monitor cut points for PA and SB bout duration.

CONCLUSION

Adults with LL OA may be at an increased risk of noncommunicable diseases due to low PA and high SB levels. It is important to consider age, sex, and BMI when investigating behavior patterns in those with LL OA.

Temporal Relations Between Pain Catastrophizing and Adverse Health and Mental Health Outcomes After Whiplash Injury

OBJECTIVES

Pain catastrophizing has been shown to be a prognostic indicator for pain severity and the co-occurrence of mental health conditions such as depression and post-traumatic stress disorder after whiplash injury. However, the pattern of available findings is limited in its implications for the possible "antecedent" or "causal" role of pain catastrophizing. The purpose of the present study was to examine the temporal relations between pain catastrophizing, pain severity, depressive symptoms, and post-traumatic stress symptoms (PTSS) in individuals receiving treatment for whiplash injury.

MATERIALS AND METHODS

The sample consisted of 388 individuals enrolled in a multidisciplinary program for whiplash injury. Participants completed self-report measures of pain catastrophizing, pain severity, depressive symptoms, and PTSS at the time of admission, mid-treatment (4 week), and treatment completion (7 week). A cross-lagged panel analysis was used to examine the temporal relations between pain catastrophizing, pain severity, depressive symptoms, and PTSS across all 3 timepoints.

RESULTS

Model fit was acceptable after the inclusion of modification indices. Pain catastrophizing at the time of admission predicted all other variables at 4 weeks. Pain catastrophizing at 4 weeks also predicted all other variables at 7 weeks. In addition, some bidirectional relations were present, particularly for variables assessed at week 4 and week 7.

DISCUSSION

Findings support the view that pain catastrophizing might play a transdiagnostic role in the onset and maintenance of health and mental health conditions. The findings call for greater emphasis on the development of treatment techniques that target pain catastrophizing in intervention programs for whiplash injury.

Everyday Pain in Middle and Later Life: Associations with Daily and Momentary Present-Moment Awareness as One Key Facet of Mindfulness

This study investigated everyday associations between one key facet of mindfulness (allocating attention to the present moment) and pain. In Study 1, 89 community-dwelling adults (33-88 years; Mage = 68.6) who had experienced a stroke provided 14 daily end-of-day present-moment awareness and pain ratings. In Study 2, 100 adults (50-85 years; Mage = 67.0 years) provided momentary present-moment awareness and pain ratings three times daily for 10 days. Multi-level models showed that higher trait present-moment awareness was linked with lower overall pain (both studies). In Study 1, participants reported less pain on days on which they indicated higher present-moment awareness. In Study 2, only individuals with no post-secondary education reported less pain in moments when they indicated higher present-moment awareness. Findings add to previous research using global retrospective pain measures by showing that present-moment awareness might correlate with reduced pain experiences, assessed close in time to when they occur.

Predictors of neuropathic pain and related functional disability in sciatica patients: a cross-sectional study

PURPOSE

The aim of the present paper was to assess neuropathic pain and its predictors among patients with sciatica. In addition, we sought to investigate the predictors of functional disability in sciatica patients with neuropathic pain.

METHODS

A cross-sectional study was carried out on a sample of 100 sciatica patients aged 18 years and older with a radiating pain from the lower back down to the leg below the knee. Information about socio-demographic characteristics, duration of symptoms, being treated or not, type of treatment, side of sciatica, presence of back pain, leg pain occurrence, leg pain intensity, functional disability and pain catastrophizing were collected.

RESULTS

Of the total patients, 57% had neuropathic pain. Multivariable analysis showed that leg pain intensity was higher in the neuropathic pain group as compared to the non-neuropathic pain group. Also, patients with left sciatica were less likely to have neuropathic pain than patients with right sciatica. Patients with neuropathic pain having high levels of pain catastrophizing and being on bed rest for at least one week were at a higher risk of developing functional disability as compared to their counterparts.

CONCLUSION

Low levels of pain catastrophizing and less bed rest should be considered in interventions aimed at improving the functional ability for sciatica patients with neuropathic pain.

Causal effect of physical activity and sedentary behaviors on the risk of osteoarthritis: a univariate and multivariate Mendelian randomization study

There is still a lot of ambiguity about the link between physical activity (PA), sedentary behaviors (SBs) and osteoarthritis (OA). This study aimed to investigate the causal relationship of PA/SBs on the risk of OA. A univariate and multivariate Mendelian randomization (MR) analysis was conducted to investigate the causal effect of five PA phenotypes and three SB phenotypes on overall OA, knee OA, hip OA, total hip arthroplasty, and total knee arthroplasty (TKA). MR methods used were inverse-variance weighting, MR-Egger regressions, and weighted median. Sensitivity analysis examined horizontal pleiotropy and heterogeneity, and confirmed the reliability of the results. After false discovery rate, light do-it-yourself (DIY) activities decreased the risk for overall OA (OR: 0.32, 95% CI 0.16-0.65), and knee OA (OR: 0.26, 95% CI 0.12-0.51). Resulting in a decreased risk of walking for pleasure on overall OA (OR: 0.87, 95% CI 0.70-1.04) and knee OA (OR: 0.14, 95% CI 0.06-0.32) was also observed. Television viewing, however, significantly increased the risk of OA, knee OA, hip OA, and TKA. MVMR findings revealed independent causal impacts of walking for pleasure and watching television on overall and knee OA, taking into account BMI, smoking, and education. This study suggested that light DIY and walking for pleasure were beneficial for preventing OA, and the risk of OA and TKA increased with prolonged television watching.

Factors that influence older adults' participation in physical activity: a systematic review of qualitative studies

BACKGROUND

Despite the advantages of physical activity (PA), older adults are often insufficiently active to maximise health. Understanding factors that influence PA engagement will support well-designed interventions for older people. Our aim was to review the qualitative evidence exploring the factors affecting older adults' engagement in PA.

METHODS

We searched six electronic databases for studies of community-dwelling older adults (≥70 years) including qualitative methods. We excluded studies of a single-disease group, individuals with cognitive impairment and care home residents. Methodological rigour was assessed with the Critical Appraisal Skills Programme, and framework synthesis was applied using the Capability Opportunity Motivation-Behaviour (COM-B) model, which hypothesises that behaviour is influenced by three factors: capability, opportunity and motivation.

RESULTS

Twenty-five studies were included in the review (N = 4,978; mean 79 years) and 32 themes were identified. Older adults' capability was influenced by functional capacity (e.g. strength) and perceived risk of injury from PA (e.g. falls). Opportunity was impacted by the environment 'fit' (e.g. neighbourhood safety), the availability of social interaction and socio-cultural ageing stereotypes. PA was motivated by identifying as an 'exerciser', health gains and experiencing positive emotions (e.g. enjoyment), whereas negative sensations (e.g. pain) reduced motivation.

CONCLUSIONS

The qualitative synthesis showcased a complex web of interacting factors influencing PA between the sub-domains of COM-B, pinpointing directions for intervention, including a focus on whole systems approaches. There was a lack of research exploring PA influences in the oldest old and in low-income countries. Future research should seek to involve under-served groups, including a wider diversity of older people.

Change in Pain During Physical Activity Following Total Knee Arthroplasty: Associations With Improved Physical Function and Decreased Situational Pain Catastrophizing

Background and Objectives

Knee osteoarthritis is one of the primary causes of chronic pain among older adults and because of the aging population, the number of total knee arthroplasties (TKAs) performed is exponentially increasing. While pain reduction is a goal of TKA, movement-evoked pain is rarely assessed pre- and post-TKA. We characterized the distributions of change in pain, function, and situational catastrophizing in patients from presurgery to 3 months postsurgery and explored associations among these pre-post changes.

Research Design and Methods

This prospective study longitudinally assessed movement-evoked pain, function, and situational catastrophizing in patients with knee osteoarthritis (N = 92) using in-person performance-based tests (6-min walk test [6MWT], stair-climb test [SCT]) prior to and 3 months after TKA. Patients also completed the Western Ontario McMaster Universities Scales (WOMAC) pain and function subscales, and Pain Catastrophizing Scale, presurgery and 3- and 6-months postsurgery.

Results

Movement-evoked pain and function on performance tests significantly improved from pre- to post-TKA. Improved SCT function was associated with reduced SCT pain and catastrophizing. Similarly, reduced pain during the SCT was associated with reduced catastrophizing during the SCT. However, 6MWT function was not associated with 6MWT pain or catastrophizing; yet reduced pain during the 6MWT was associated with reduced catastrophizing during the 6MWT. Reduced movement-evoked pain during both performance tests was consistently associated with improved WOMAC function and pain, whereas improved function on performance tests was inconsistently associated with WOMAC function and pain. Notably, greater movement-evoked pain on both performance tests at 3-month post-TKA was associated with worse WOMAC function and pain at 6 months, whereas better function on performance tests at 3 months was associated with better WOMAC function, but not related to WOMAC pain at 6 months.

Discussion and Implications

Findings highlight the importance of situation-specific and in vivo assessments of pain and catastrophizing during physical activity.

Domain-specific physical activity, sedentary behavior, subjective health, and health-related quality of life among older adults

PURPOSE

This study aims to investigate the association between domain-specific physical activity (PA), sedentary behavior, subjective health perception, and health-related quality of life (HR-QoL) in Korean adults aged ≥ 65 years.

METHODS

This cross-sectional study analyzed 6,004 older adults from the Korean National Health and Nutrition Examination Survey 2017-2020. PA and sedentary behavior were measured using a global PA questionnaire, and HR-QoL was assessed using the EuroQol-5 Dimension (EQ-5D, three-level version). Multiple logistic regression was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) after adjusting for confounding parameters.

RESULTS

Older adults who were physically active at work showed a negative association with subjectively good health and HR-QoL, whereas those physically active in transport or leisure time showed a positive association with subjectively good health and HR-QoL. Older adults highly engaged in sedentary behavior showed a worse perception of health and HR-QoL. Compared to high sedentary behavior and physical activity during leisure time or transport, the EQ-5D index was higher than that of their counterparts.

CONCLUSION

Both domain-specific PA and sedentary behavior were significantly associated with older adults' perception of health and HR-QoL. Interventions are needed to improve HR-QoL by reducing sedentary behavior and encouraging physical activity in transportation or leisure time among adults aged 65 years and above.

Exploring pain catastrophizing and its associations with low disease activity in rheumatic inflammatory disorders

Pain catastrophizing is a maladaptive mechanism associated with the exaggerated experience of pain, increased rumination and feelings of helplessness. The main objective of this study was to explore whether increased pain catastrophizing is independently associated with a lower proportion of low disease activity (LDA) in rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondylarthritis (axSpA). Demographics, comorbidities, treatment, disease activity measures and patient-reported outcome data were recorded in RA, PsA and axSpA patients. Pain catastrophizing score (PCS) was assessed using a standardised questionnaire. For each diagnosis, composite disease activity scores with distinct cut-off values for LDA, i.e. DAS28-CRP (RA), DAPSA (PsA) and ASDAS-CRP (axSpA) were calculated and used as the dependent variable in logistic regression reflecting LDA achieved. A total of one thousand two hundred and twenty nine patients were included: 580 with RA, 394 with PsA and 255 with axSpA. In the multivariable analysis, pain catastrophizing was independently associated with LDA rates in axSpA (OR 0.33, 95% CI [0.12, 0.88]) amongst tested groups. In RA (OR 0.90, 95% CI [0.64, 1.28]) and PsA (OR 0.77, 95% CI [0.55, 1.07]), a statistically significant association was not observed. Higher PCS was independently associated with not achieving LDA in axSpA. Our data, however, indicate that pain catastrophizing, which also reflects a patient's personality traits and coping abilities, plays a less important role for the patient than general pain perception.

The relationship between experience of knee pain and physical activity participation: A scoping review of quantitative studies

Objectives

Physical activity (PA) in people with knee pain can help to relieve pain and prevent health problems. However, engaging in regular PA is challenging for them due to chronic musculoskeletal pain. An understanding of how the experience of knee pain affects PA is important to minimize the negative effects of knee pain on participation in PA among this population. We examined the quantitative evidence describing the relationship between the experience of knee pain and participation in PA.

Methods

We conducted a scoping review based on the PRISMA-ScR process across 27 items and Peters' methodological framework. Searches using keywords were performed in Medline, PsycINFO, CINAHL and Scopus.

Results

Nine studies were included in this review. While one study clearly showed that increased knee pain increased PA, four studies indicated that knee pain decreased PA among individuals with knee pain. One study revealed that increased knee pain decreased moderate PA, but no significant difference with light intensity PA. Three studies showed that knee pain had no impact on PA. Moreover, psychological factors (catastrophizing and pain-related activity interference) and certain activities of daily living were risk factors for insufficient PA among people with knee pain.

Conclusions

The limited quantitative evidence on the relationship between the experience of knee pain and PA participation highlights a gap in the knowledge base. The review findings found mixed results, with a negative, positive or no relationship between knee pain and levels of PA among individuals with knee pain. The findings also suggest that the relationship can be affected by psychological factors and different levels and types of PA. Therefore, practitioners should consider multi-component interventions which aim to increase PA levels of individuals with knee pain, after considering the above mediating factors.

Brain system segregation and pain catastrophizing in chronic pain progression

Pain processing involves emotional and cognitive factors that can modify pain perception. Increasing evidence suggests that pain catastrophizing (PC) is implicated, through pain-related self-thoughts, in the maladaptive plastic changes related to the maintenance of chronic pain (CP). Functional magnetic resonance imaging (fMRI) studies have shown an association between CP and two main networks: default mode (DMN) and dorsoattentional (DAN). Brain system segregation degree (SyS), an fMRI framework used to quantify the extent to which functional networks are segregated from each other, is associated with cognitive abilities in both healthy individuals and neurological patients. We hypothesized that individuals suffering from CP would show worst health-related status compared to healthy individuals and that, within CP individuals, longitudinal changes in pain experience (pain intensity and affective interference), could be predicted by SyS and PC subdomains (rumination, magnification, and helplessness). To assess the longitudinal progression of CP, two pain surveys were taken before and after an in-person assessment (physical evaluation and fMRI). We first compared the sociodemographic, health-related, and SyS data in the whole sample (no pain and pain groups). Secondly, we ran linear regression and a moderation model only in the pain group, to see the predictive and moderator values of PC and SyS in pain progression. From our sample of 347 individuals (mean age = 53.84, 55.2% women), 133 responded to having CP, and 214 denied having CP. When comparing groups, results showed significant differences in health-related questionnaires, but no differences in SyS. Within the pain group, helplessness (β = 0.325; p = 0.003), higher DMN (β = 0.193; p = 0.037), and lower DAN segregation (β = 0.215; p = 0.014) were strongly associated with a worsening in pain experience over time. Moreover, helplessness moderated the association between DMN segregation and pain experience progression (p = 0.003). Our findings indicate that the efficient functioning of these networks and catastrophizing could be used as predictors of pain progression, bringing new light to the influence of the interplay between psychological aspects and brain networks. Consequently, approaches focusing on these factors could minimize the impact on daily life activities.

The Relationship Between Pain Intensity and Pain-Related Activity Patterns in Older Adults with Chronic Musculoskeletal Pain: Mediating Roles of Pain Resilience and Pain Catastrophizing

Purpose

To explore the relationship between pain intensity, pain resilience, pain catastrophizing, and pain-related activity patterns in older adults with chronic musculoskeletal pain (CMP).

Patients and Methods

A total of 220 elderly Chinese with chronic musculoskeletal pain were recruited from a tertiary general hospital. Participants completed several measures including a demographic questionnaire, Brief Pain Inventory (BPI), Pain Resilience Scale (PRS), Pain Catastrophizing Scale (PCS), and Patterns of Activity Measure-Pain (POAM-P). Moreover, Process version 3.5 plug-in SPSS26 was used to test the mediation effect between variables.

Results

The scores of POAM-P in older adults with CMP from high to low were: avoidance (27.39 ± 8.10), pacing (24.25 ± 9.48), and overdoing (16.65 ± 10.95). Mediation analysis revealed that pain resilience and pain catastrophizing mediated the relationship between pain intensity and pain-related activity patterns (avoidance and pacing) in older adults with CMP.

Conclusion

These results provide evidence for the role of pain resilience and pain catastrophizing in the relationship between pain intensity and pain-related activity patterns. Interventions targeting these factors should be included in activity management programs for elderly CMP patients. It may be possible to reduce the negative impact of pain intensity on activity patterns by improving pain resilience and reducing pain catastrophizing.

Effects of Depression, Anxiety, and Pain Catastrophizing on Total Hip Arthroplasty Patient Activity Level

BACKGROUND

Improvements in psychological factors are strongly associated with increased physical activity in the general population. The effects of depression, anxiety, and pain catastrophizing on activity level have not been thoroughly explored in patients undergoing total hip arthroplasty (THA). Mental health markedly influences patient perspectives on treatment success and quality of life. We hypothesized that improvements in screenings for depression, anxiety, and catastrophizing correlate with improvements in activity levels after THA.

METHODS

Two hundred ninety two patients (313 hips) who underwent THA with a minimum 1-year (mean 615 ± 270 days) follow-up completed preoperative and postoperative surveys containing the University of California Los Angeles (UCLA) Activity Score, Hospital Anxiety Depression Scale (HADS), Pain Catastrophizing Scale (PCS), and Depression Anxiety Stress Scale-21 (DASS). Wilcoxon signed-rank tests were performed between preoperative and postoperative times for outcome measures. Partial Spearman's rank-order correlations were performed between the change in UCLA Score and the change in HADS, PCS, and DASS.

RESULTS

There were significant improvements in UCLA Score (P value < .0001) and every subscale of PCS, HADS, and DASS (P values < .0001). Significant negative correlations existed between change in UCLA Score and change in HADS-anxiety (r_s = -0.21, P value < .001), change in HADS-depression (r_s = -0.23, P value < .001), and change in DASS-anxiety (r_s = -0.22, P value = .004) following THA. Weaker significant negative correlations existed between change in UCLA Score and change in the remaining PCS (P values = .006) and DASS-depression(P value = .037) subscales.

CONCLUSION

Improvements in patient-reported depression, anxiety, and pain catastrophizing screenings following THA were associated with increased activity levels. Patients who were screened for catastrophizing, depression, and anxiety achieved statistically and clinically meaningful improvements in symptoms following THA. Addressing patient mental health provides another avenue for holistic care of THA patients.

Combined influence of sedentary behaviours and chronic pain on depressive symptoms in older Korean adults with hypertension

AIMS

Depressive symptoms in hypertensive patients are linked to poor adherence to treatment. Sedentary behaviours and chronic pain can increase blood pressure and depressive symptoms, respectively. However, the impact of their coexistence on depressive symptoms in older adults with hypertension has not yet been investigated. This study aimed to identify the combined influence of sedentary behaviours and chronic pain on depressive symptoms in older adults with hypertension in Korea.

METHODS AND RESULTS

This cross-sectional study used data from the sixth Korea National Health and Nutrition Examination Survey from January to December 2014. The survey adopted multistage stratified sampling by geographical region, gender, and age. For the data analysis, a total of 573 patients with hypertension aged 65 years or older were included. Approximately, 61.0% of depressed older patients had both sedentary behaviours and chronic pain compared with patients without depressive symptoms. In multivariate logistic regression analysis, compared with patients without either sedentary behaviours or chronic pain, older adults with hypertension who presented both sedentary behaviours, and chronic pain had the highest risk of depressive symptoms (odds ratio = 13.86, 95% confidence interval = 5.87-32.71; P < 0.001).

CONCLUSION

Coexistence of sedentary behaviours and chronic pain in older hypertensive patients may lead to depressive symptoms. Evaluating both sedentary behaviours and chronic pain when assessing depressive symptoms in patients with hypertension would be beneficial in planning a patient-centred approach for controlling blood pressure. More prospective cohort studies with larger samples are required to identify the causal relationships.

Fitbit Activity, Quota-Based Pacing, and Physical and Emotional Functioning Among Adults With Chronic Pain

Physical activity can improve function in patients with chronic pain, however, adherence is low, in part due to inconsistent activity patterns. Smart wearable activity trackers, such as Fitbits, may help promote activity. In our program for chronic pain, we examined: 1) Fitbit activity patterns (ie, step count, moderate-to-vigorous physical activity (MVPA), sedentary behavior), and 2) whether achievement of weekly, individualized Fitbit step goals was associated with functional outcomes. We conducted a secondary analysis of Fitbit data from our 10-week mind-body activity program for chronic pain (GetActive-Fitbit arm, N = 41). Participants self-reported emotional and physical function and completed performance-based and accelerometer-based assessments. From week 1 to week 10, 30% of participants increased >800 steps; 32.5% increased MVPA; and 30% decreased sedentary behavior. Only step count significantly changed across time with mean steps peaking at week 8 (M = +1897.60, SD = 467.67). Fitbit step goal achievement was associated with improvements in anxiety (ß = -.35, CI [-2.80, -.43]), self-reported physical function (ß = -.34, CI [-5.17, 8.05]), and performance-based physical function (ß = .29, CI [-71.93, 28.38]), but not accelerometer-based physical function or depression. Adhering to individualized Fitbit step goals in the context of a mind-body activity program may improve anxiety and self-reported and performance-based physical function. PERSPECTIVE: We examine Fitbit activity patterns and the association between quota-based pacing and functional outcomes within a mind-body activity program for adults with chronic pain. Complementing quota-based pacing and coping skills with Fitbits may be a useful approach to promote activity engagement and behavior change in chronic pain populations.

Combined effects of lifestyle and psychosocial factors on central sensitization in patients with chronic low back pain: A cross-sectional study

BACKGROUND

Central sensitization is one cause of chronic low back pain. Lifestyle and psychosocial factors are involved in the exacerbation of central sensitization. However, the combined effects of these factors on central sensitization in patients with chronic low back pain are unclear. The objective of this study was to investigate the combined effects of lifestyle and psychosocial factors on central sensitization in patients with chronic low back pain.

METHODS

This was a cross-sectional study. The participants were recruited from three orthopedic clinics for a total of 70 patients with chronic low back pain. Data were analyzed using hierarchical multiple regression analysis. In Model 1, lifestyle factors such as sleep quality, physical activity, sitting time, and perceived stress were included. Model 2 included psychosocial factors (pain catastrophizing, anxiety, and depression).

RESULTS

The data showed that sleep (b = 0.30) and perceived stress (b = 0.47) were significantly correlated in Model 1, and anxiety (b = 0.41) and perceived stress (b = 0.27) were significantly correlated in Model 2. Furthermore, contributions from sleep (b = 0.14) decreased, and no significant correlations were observed. The coefficient of determination increased significantly from Model 1 to Model 2 (ΔR ² = 0.12, p < 0.05).

CONCLUSIONS

In this study, we clarified that perceived stress and anxiety were correlated with central sensitization in patients with chronic low back pain. In addition, sleep quality mediates anxiety and may be associated with central sensitization.

Active or passive pain coping: Which predicts daily physical and psychosocial functioning in people with chronic pain and spinal cord injury?

PURPOSE/OBJECTIVE

Despite medical and psychotherapeutic treatments, chronic pain is one of the most challenging and disabling conditions for individuals with spinal cord injury (SCI). A growing body of research has demonstrated that pain coping strategies are effective for the adjustment of pain. However, we still lack an understanding of how passive pain coping and active pain coping relate to daily physical and psychosocial functioning for people with chronic pain and SCI. The current study used end-of-day (EOD) diary data to examine associations of passive and active pain coping with same-day independence, positive affect and well-being, social participation, pain catastrophizing, depressive symptoms, and pain interference in adults with chronic pain and SCI.

RESEARCH METHOD/DESIGN

This observational study in N = 124 individuals with SCI (mean age = 47.53 years; 74.2% male, 25.8% female) used a combination of baseline surveys and seven consecutive days of end-of-day (EOD) diaries.

RESULTS

Results of multilevel modeling showed that, beyond the effects of key demographic variables, clinical variables (e.g., time since injury, mobility) and daily pain intensity, increased daily passive coping (from that person's average) related to increased same-day depressive symptoms (B = .29; p < .001), pain catastrophizing (B = .28; p < .001) and decreased same-day positive affect and well-being (B = -.31; p = .02). Increased daily active coping was related to higher same-day catastrophizing (B = .09; p < .05).

CONCLUSIONS/IMPLICATIONS

Behavioral interventions for pain often emphasize adoption and practice of new active coping strategies. Findings highlight the potential importance of also addressing passive coping strategies in services of improvement in physical and psychosocial outcomes in individuals with chronic pain and SCI.

Assessment of the quality of life in patients with chronic degenerative osteoarticular diseases (gonarthrosis, coxarthrosis)

Quality of life is a multidimensional concept that refers to the individual perception of one's own life and that includes aspects of individual health (cultural, social or psychological). Arthrosis is a progressive condition that involves damage to cartilage, damage to the subchondral bone and changes in the synovial and periarticular structures. Material and method. The study aims to provide information on the impact of degenerative osteoarticular diseases (gonarthrosis and coxarthrosis) while assessing the health of the population in Suceava county (one of the most affected counties in Romania due to the COVID-19 pandemic) by studying a sample of the study population. Based on the results obtained, an analysis can be made and then general ideas about the entire population. Results and discussions. The application of the SF-36 questionnaire helps to identify ways to improve the quality of life of patients diagnosed with degenerative osteoarticular disorders, gonarthrosis and coxarthrosis, and to prevent the negative aspects. In the health field, quality of life is an indicator used to assess the physical, mental and social effects of illness and the applied medical treatments, as well as to analyze the needs of a patient during the illness. Conclusions. The suffering caused by this type of disease has an impact on the quality of life of patients, both physically and emotionally. A special role in assessing the quality of life in these patients is their emotional condition and the acceptance of their functional status, trying to improve it. The quality of life of patients with chronic degenerative osteoarticular diseases is a public health issue, by the duration of the disease, by family, social, economic and medical implications. Keywords: quality of life, degenerative osteoarticular diseases, general health conditions

Pain catastrophizing: A patient-centered approach to assessment

ABSTRACT

Pain is a subjective experience and its perception and expression vary widely. Pain catastrophizing, which refers to patients' thoughts or feelings about their pain, may impact their communication of pain and nurses' subsequent response. This article discusses how nurses can more readily recognize, assess, and manage pain catastrophizing.

Accelerometer-Based Physical Activity Patterns and Associations With Outcomes Among Individuals With Osteoarthritis

BACKGROUND

This study examined patterns of physical activity and associations with pain, function, fatigue, and sleep disturbance among individuals with knee or hip osteoarthritis.

METHODS

Participants (n = 54) were enrolled in a telephone-based physical activity coaching intervention trial; all data were collected at baseline. Self-reported measures of pain and function (WOMAC [Western Ontario and McMaster Universities Osteoarthritis Index] subscales), fatigue (10-point numeric rating scale), and PROMIS (Patient-Reported Outcomes Information System) Sleep Disturbance were collected via telephone. Accelerometers were mailed to participants and were worn for at least 3 days. Proportion of time participants spent in sedentary behavior during the morning (from wake until 12:00 pm), afternoon (12:00 pm until 5:59 pm) and evening (6:00 pm until sleep) each day was averaged across all days of wear. Pearson correlations assessed associations between activity and self-reported measures.

RESULTS

Participants spent a large proportion of time in sedentary behavior: 65.6% of mornings, 70.0% of afternoons, and 76.6% of evenings. Associations between proportion of time spent in sedentary behavior and reported outcomes were generally strongest in the afternoon, strongest for WOMAC function, and lowest for PROMIS Sleep Disturbance. In the evening hours, sedentary time was most strongly associated with fatigue.

CONCLUSIONS

Overall, findings stress the importance of reducing sedentary behavior among adults with osteoarthritis and suggest behavioral interventions may be strengthened by considering patients' within-day variation in symptoms and activity.

Measurement of physical activity and prevention of physical inactivity/sedentary behaviors in patients with septic knee arthritis before and after hospital discharge: A case report

BACKGROUND

Patients with septic knee arthritis tend to have prolonged pain, which may lead to a decrease in physical activity (PA). Pain catastrophizing, which is associated with chronic pain, is known to be a limiting factor for PA. An objective measurement of PA in patients with septic knee arthritis has not been reported. Here we describe the accelerometry-based measurement of the PA of a patient with septic knee arthritis before and after discharge, and we report the ability of follow-up outpatient physical therapy to increase PA.

METHODS

A 70-year-old Japanese woman admitted to the hospital with a diagnosis of left septic knee arthritis presented with prolonged pain and pain catastrophizing in the left knee. We investigated her pre- and post-discharge PA by using an accelerometer. We also investigated her physical function, pain, and pain catastrophizing as a possible influence on PA. Follow-up outpatient physical therapy (consisting of PA feedback, counseling, and reassurance) was performed to improve the patient's physical function and increase her PA.

RESULTS

The patient's PA indicated general inactivity from pre-discharge to 1 month post-discharge, especially immediately post-discharge (sedentary behavior [SB]: 540-571.3 min/daytime, light-intensity PA: 145.8-177.8 min/daytime). The follow-up outpatient physical therapy was effective in increasing her physical function and PA (a 31-min decrease in SB, a 32-min increase in light-intensity PA) but was not effective in reducing her pain or pain catastrophizing.

DISCUSSION

Contrary to the general trend, this patient showed a decrease in PA after hospital discharge compared to PA during hospitalization. Follow-up outpatient physical therapy had the effect of increasing the patient's PA, which was decreased immediately post-discharge.

Physiological Changes and Pathological Pain Associated with Sedentary Lifestyle-Induced Body Systems Fat Accumulation and Their Modulation by Physical Exercise

A sedentary lifestyle is associated with overweight/obesity, which involves excessive fat body accumulation, triggering structural and functional changes in tissues, organs, and body systems. Research shows that this fat accumulation is responsible for several comorbidities, including cardiovascular, gastrointestinal, and metabolic dysfunctions, as well as pathological pain behaviors. These health concerns are related to the crosstalk between adipose tissue and body systems, leading to pathophysiological changes to the latter. To deal with these health issues, it has been suggested that physical exercise may reverse part of these obesity-related pathologies by modulating the cross talk between the adipose tissue and body systems. In this context, this review was carried out to provide knowledge about (i) the structural and functional changes in tissues, organs, and body systems from accumulation of fat in obesity, emphasizing the crosstalk between fat and body tissues; (ii) the crosstalk between fat and body tissues triggering pain; and (iii) the effects of physical exercise on body tissues and organs in obese and non-obese subjects, and their impact on pathological pain. This information may help one to better understand this crosstalk and the factors involved, and it could be useful in designing more specific training interventions (according to the nature of the comorbidity).

Structural and Functional Abnormalities in Knee Osteoarthritis Pain Revealed With Multimodal Magnetic Resonance Imaging

The knee osteoarthritis (KOA) pain is the most common form of arthritis pain affecting millions of people worldwide. Long-term KOA pain causes motor impairment and affects affective and cognitive functions. However, little is known about the structural and functional abnormalities induced by long-term KOA pain. In this work, high-resolution structural magnetic resonance imaging (sMRI) and resting-state functional MRI (rs-fMRI) data were acquired in patients with KOA and age-, sex-matched healthy controls (HC). Gray matter volume (GMV) and fractional amplitude of low-frequency fluctuation (fALFF) were used to study the structural and functional abnormalities in patients with KOA. Compared with HC, patients with KOA showed reduced GMV in bilateral insula and bilateral hippocampus, and reduced fALFF in left cerebellum, precentral gyrus, and the right superior occipital gyrus. Patients with KOA also showed increased fALFF in left insula and bilateral hippocampus. In addition, the abnormal GMV in left insula and fALFF in left fusiform were closely correlated with the pain severity or disease duration. These results indicated that long KOA pain leads to brain structural and functional impairments in motor, visual, cognitive, and affective functions that related to brain areas. Our findings may facilitate to understand the neural basis of KOA pain and the future therapy to relieve disease symptoms.

Gait-related Self-efficacy is Low in Older Adults with Knee Osteoarthritis: A Preliminary Study

OBJECTIVE

To investigate the differences in self-efficacy (SE) for walking tasks between older patients with knee osteoarthritis (OA) and older adults without knee OA.

METHODS

A cross-sectional design was employed. Older patients with radiographic knee OA and community-dwelling older adults without knee OA as controls were enrolled in the study. SE for the walking task was assessed using the modified gait efficacy scale (mGES). A Wilcoxon rank-sum test was used to compare the mGES between the groups of participants. A Tobit regression model was used to estimate the difference in mGES. The presence of radiographic knee OA was used as an independent variable. Sex (women), age, and body mass index were used as potential confounding variables in the model.

RESULTS

After exclusion, 78 participants (n=40 with knee OA, n=38 controls) were included. The mGES was lower in patients with knee OA than in controls. In the Tobit regression model adjusted for confounding factors, mGES in patients with knee OA was estimated to be 26.8 (95% confidence interval [CI]: 15.8-37.8) points lower than in controls.

CONCLUSION

This study demonstrated that mGES was lower in older patients with knee OA than in older adults without knee OA.

Applications of Wearable Technology in a Real-Life Setting in People with Knee Osteoarthritis: A Systematic Scoping Review

With the growing number of people affected by osteoarthritis, wearable technology may enable the provision of care outside a traditional clinical setting and thus transform how healthcare is delivered for this patient group. Here, we mapped the available empirical evidence on the utilization of wearable technology in a real-world setting in people with knee osteoarthritis. From an analysis of 68 studies, we found that the use of accelerometers for physical activity assessment is the most prevalent mode of use of wearable technology in this population. We identify low technical complexity and cost, ability to connect with a healthcare professional, and consistency in the analysis of the data as the most critical facilitators for the feasibility of using wearable technology in a real-world setting. To fully realize the clinical potential of wearable technology for people with knee osteoarthritis, this review highlights the need for more research employing wearables for information sharing and treatment, increased inter-study consistency through standardization and improved reporting, and increased representation of vulnerable populations.

Patient perspectives from the multi-disciplinary chronic pain clinic: a qualitative study

Aim: The chronic pain clinic (CPC) is a multi-disciplinary program that incorporates pharmacological and non-pharmacological methods, including First Nations healing strategies, to manage pain, improve functioning and reduce opioid misuse among patients with chronic pain in Regina, Canada. Materials & methods: The care experiences of ten current clients were explored using a narrative interview approach. Results: The CPC provides high-quality and safe care for effective chronic pain management. Clients noted pain reduction and improvements in sleep, mobility, functionality, and mood. First Nation clients emphasized the importance of traditional healing strategies. Conclusion: This unique comprehensive multi-modal approach which incorporates First Nations healing strategies is effective in supporting the unique needs of local clients.

Physical activity behavior in the first month after mild traumatic brain injury is associated with physiological and psychological risk factors for chronic pain

OBJECTIVE

The purpose of this study was to determine whether self-reported physical activity (PA) in the first month after mild traumatic brain injury (mTBI) predicts endogenous pain modulatory function and pain catastrophizing at 1 to 2 weeks and 1 month after injury in patients with mTBI.

METHODS

Patients with mild traumatic brain injury completed study sessions at 1 to 2 weeks and 1 month after injury. Assessments included a headache survey, Pain Catastrophizing Scale, International Physical Activity Questionnaire-Short Form, and several quantitative sensory tests to measure endogenous pain modulatory function including conditioned pain modulation (CPM), temporal summation, and pressure pain thresholds of the head. Hierarchical linear regressions determined the relationship between the PA variables (predictors) and pain catastrophizing and pain modulation variables (dependent variables) cross-sectionally and longitudinally, while controlling for potential covariates.

RESULTS

In separate hierarchical regression models, moderate PA, walking, and total PA at 1 to 2 weeks after injury predicted pain inhibition on the CPM test at 1 month, after controlling for significant covariates. In addition, a separate regression revealed that minutes sitting at 1 month predicted CPM at 1 month. Regarding predicting pain catastrophizing, the regression results showed that sitting at 1 to 2 weeks after injury significantly predicted pain catastrophizing at 1 month after injury.

CONCLUSION

Greater self-reported PA, especially moderate PA, 1 to 2 weeks after injury longitudinally predicted greater pain inhibitory capacity on the CPM test at 1 month after injury in patients with mTBI. In addition, greater sedentary behavior was associated with worse pain inhibition on the CPM test and greater pain catastrophizing at 1 month after injury.

Pain catastrophizing mediates rapid benefits of accessing in-person chiropractic care during the COVID-19 lockdown

Background

In March 2020, the COVID‐19 pandemic forced the Spanish government to declare a state of emergency. A stringent lockdown was enforced, restricting access to healthcare services, including chiropractic. Reduced access to care provision in combination with psychological stress, social isolation and physical inactivity during the lockdown were shown to negatively influence pain conditions. However, data on strategies to mitigate the impact of the pandemic on these conditions are lacking.

Methods

Upon easing of restrictions in May 2020, 51 chiropractic clinics throughout Spain pseudo‐randomly invited patients, recruiting a total of 385 participants. During a 14‐day period, participants were exposed to in‐person chiropractic care in either one (n = 177) or multiple encounters (n = 109) or to no care (n = 99). The effects of access to chiropractic care on patients’ pain‐related and psychological outcomes were assessed online through validated self‐reported questionnaires before and after the period of care. Coprimary outcomes included pain intensity, pain interference and pain cognitions.

Results

When comparing to participants without access to care, pain intensity and interference were significantly decreased at follow‐up, irrespective of the number of encounters. Kinesiophobia was also significantly reduced at follow‐up, though only after multiple encounters. The relationship between fear of movement, changes in pain intensity and interference was mediated by catastrophizing.

Conclusion

Access to in‐person chiropractic care may provide pain relief, associated with reductions in interference and pain cognitions. Prioritizing in‐person care for patients with maladaptive pain cognitions may help dampen the detrimental consequences of the pandemic on physical and psychological well‐being.

Exponential correlations among neuropathic components, pain intensity, and catastrophic thoughts in patients with musculoskeletal pain disorder

BACKGROUND

Neuropathic components and catastrophic thoughts contribute to the quality of life impairments in patients with chronic pain. This retrospective cross-sectional observational study examined the extent to which neuropathic components affect pain intensity and catastrophic thoughts using a mathematical model.

METHODS

Participants with chronic pain with spinal or joint disorders were rated for pain intensity using a numerical rating scale (NRS), painDETECT questionnaire (PDQ), and pain catastrophizing scale (PCS). We plotted to scatter plots between PDQ and either NRS or PCS and drew best-fit lines for patients with leg pain only. We divided patients with both leg and back pain into two clusters: located above or below the baselines, and then we drew the best-fit lines for each cluster. We performed factor analysis on PDQ items and developed and validated a discriminant to identify patients located above the baseline in another cohort of musculoskeletal disorders.

RESULTS

We analyzed 163 patients with lumbar disorders and 205 patients with joint disorders. PDQ correlated exponentially with NRS and PCS of the patients located above the baseline in both disorder groups and correlated linearly or logarithmically in patients located below the baseline. Factor analysis revealed three sets of pain characteristics for each disorder. We developed the discriminant from PDQ items to identify patients showing exponential correlations and then validated it in another cohort of 137 patients. The coefficient for "pressure-evoked pain" was the highest in the discriminant.

CONCLUSIONS

Mathematical models indicate neuropathic components demonstrate linear correlations with NRS and PCS generally, but exponential correlations in a cluster of the patients with musculoskeletal pain. We developed and validated the discriminant based on pain characteristics to identify such patients; "pressure-evoked pain" was the most significant contributor.

What factors are associated with perceived disease onset in patients with hip and knee osteoarthritis?

Introduction

Newly symptomatic osteoarthritis (OA) is often misinterpreted as new pathology or injury, which is associated with pain intensity and incapability.

Methods

Adult patients with hip and knee OA completed measures of catastrophic thinking, depression, capability, symptom duration, and perceived injury.

Results

Symptom duration was associated with OA grade and symptoms of depression. Perceived injury was common (31%) and associated with men and knee arthritis. Capability was associated with misinterpretation of symptoms and the work status 'other,' but not radiographic severity.

Conclusions

Misinterpretation of OA symptoms is common and has a greater influence on capability than radiographic grade of pathophysiology.

Heterogeneity of the strength response to progressive resistance exercise training in older adults: Contributions of muscle contractility

BACKGROUND

Older adults display wide individual variability (heterogeneity) in the effects of resistance exercise training on muscle strength. The mechanisms driving this heterogeneity are poorly understood. Understanding of these mechanisms could permit development of more targeted interventions and/or improved identification of individuals likely to respond to resistance training interventions. Thus, this study assessed potential physiological factors that may contribute to strength response heterogeneity in older adults: neural activation, muscle hypertrophy, and muscle contractility.

METHODS

In 24 older adults (72.3 ± 6.8 years), we measured the following parameters before and after 12 weeks of progressive resistance exercise training: i) isometric leg extensor strength; ii) isokinetic (60°/sec) leg extensor strength; iii) voluntary (neural) activation by comparing voluntary and electrically-stimulated muscle forces (i.e., superimposed doublet technique); iv) muscle hypertrophy via dual-energy x-ray absorptiometry (DXA) estimates of regional lean tissue mass; and v) intrinsic contractility by electrically-elicited twitch and doublet torques. We examined associations between physiological factors (baseline values and relative change) and the relative change in isometric and isokinetic muscle strength.

RESULTS

Notably, changes in quadriceps contractility were positively associated with the relative improvement in isokinetic (r = 0.37-0.46, p ≤ 0.05), but not isometric strength (r = 0.09-0.21). Change in voluntary activation did not exhibit a significant association with the relative improvements in either isometric or isokinetic strength (r = 0.35 and 0.33, respectively; p > 0.05). Additionally, change in thigh lean mass was not significantly associated with relative improvement in isometric or isokinetic strength (r = 0.09 and -0.02, respectively; p > 0.05). Somewhat surprising was the lack of association between exercise-induced changes in isometric and isokinetic strength (r = 0.07).

CONCLUSIONS

The strength response to resistance exercise in older adults appears to be contraction-type dependent. Therefore, future investigations should consider obtaining multiple measures of muscle strength to ensure that strength adaptations are comprehensively assessed. Changes in lean mass did not explain the heterogeneity in strength response for either contraction type, and the data regarding the influence of voluntary activation was inconclusive. For isokinetic contraction, the strength response was moderately explained by between-subject variance in the resistance-exercise induced changes in muscle contractility.

Predictors of vaginal penetration in women with Provoked Vestibulodynia

This study examined whether time, treatment type, baseline individual differences, and treatment satisfaction affected the vaginal intercourse trajectories of women with Provoked Vestibulodynia (PVD) before and after psychological treatment. Women (N = 130) who received CBT or MBCT completed questionnaires prior to and 2-4 weeks, 6-, and 12-months following treatment. The odds of women engaging in vaginal penetration increased by 31% at each assessment. Baseline individual differences and treatment satisfaction predicted maintenance of or re-engagement in vaginal penetration at post-treatment. Findings suggest that women who refrain from vaginal intercourse after treatment differ from women who continue or resume this activity.

Assessing the Impact of a Hilly Environment on Depressive Symptoms among Community-Dwelling Older Adults in Japan: A Cross-Sectional Study

Although some neighborhood environmental factors have been found to affect depressive symptoms, few studies have focused on the impact of living in a hilly environment, i.e., land slope, on depressive symptoms among rural older adults. This cross-sectional study aimed to investigate whether a land slope is associated with depressive symptoms among older adults living in rural areas. Data were collected from 935 participants, aged 65 years and older, who lived in Shimane prefecture, Japan. Depressive symptoms were assessed using the Zung Self-Rating Depression Scale (SDS) and defined on the basis of an SDS score ≥ 40. Land slopes within a 400 m network buffer were assessed using geographic information systems. Odds ratios (ORs) with 95% confidence intervals (CIs) of depressive symptoms were estimated using logistic regression. A total of 215 (23.0%) participants reported depressive symptoms. The land slope was positively associated with depressive symptoms (OR = 1.04; 95% CI = 1.01-1.08) after adjusting for all confounders. In a rural setting, living in a hillier environment was associated with depressive symptoms among community-dwelling older adults in Japan.

Influence of the physical activity in the elderly people diagnosed with knee osteoarthritis during the pandemic period caused by COVID-19

Introduction. Knee osteoarthritis is considered to be a chronic disease that affects the joints by causing pain, joint stiffness and decreased functional capacity. Regular physical activity can keep and increase functional capacity, it can reduce pain by improving movement behavior. The disruption of the sedentary behavior of the elderly patients with knee osteoarthritis can lead to improved physical function and general health. The purpose of this paper is to point out the role of physical activity in the elderly people diagnosed with knee osteoarthritis during the COVID-19 pandemic. Material and method. A total of 155 patients diagnosed (clinical and imaging) with knee ostoarthritis, who were treated on an outpatient basis, from May to September 2020, were studied. The parameters assessed in the study were pain, joint stiffness, the ability to carry out daily activities, anxiety and quality of life. Results and discussion.The studied group of patients was homogeneous in terms of the weight by age group and gender. Higher values were recorded in the study group in the evaluation of patients based on scales, the results being statistically significant, with value for p<0.05, which means that the hypothesis was validated. Conclusions. Patients of the study group recorded improvementin of functional capacity, joint stability and static and dynamic balance, which allowed a faster reintegration into the family and society. Keywords: physical activity, pain, elderly people, knee osteoarthritis,

Health, Physical Activity and Musculoskeletal Symptoms among Stone, Sand, and Gravel Mine Workers: Implications for Enhancing and Sustaining Worker Health and Safety

There is little data delineating relationships between health and worker musculoskeletal symptoms (MSS), particularly among stone, sand, and gravel mine (SSGM) workers. There is also little data detailing the relationships between physical activity and MSS among these workers. A cross-sectional study using data from 459 SSGM workers was completed. Logistic regression analyses assessed relationships between health factors, physical activity, and low back, neck, shoulder, and knee MSS. Those who reported their health as very good/excellent were less likely to suffer low back and knee MSS. Those who indicated their health was poor/fair were more likely to suffer shoulder, neck, and knee MSS. Obese workers were more likely to experience knee MSS and those who smoked in the past had higher odds of neck MSS. Vigorous physical activity was mostly protective, but those performing more than 5 h of moderate physical activity each week had greater odds of shoulder and neck MSS. Given these results, workers in SSGM may benefit from targeted interventions that bolster vigorous physical activity and improve health.

Pain Catastrophizing in Older Adults with Chronic Pain: The Mediator Effect of Mood Using a Path Analysis Approach

Cognitive models of pain propose that catastrophic thinking is negatively associated with chronic pain. However, pain catastrophizing is a complex phenomenon requiring a multivariate examination. This study estimates the effects of mood variables (anxiety and depression) on pain catastrophizing in older adults with chronic pain. A postal survey addressing pain aspects was sent to 6611 people ≥ 65 years old living in south-eastern Sweden. Pain catastrophizing was measured using the pain catastrophizing scale. Anxiety and depression were assessed using two subscales of the general well-being schedule. Data were analysed using a path analysis approach. A total of 2790 respondents (76.2 ± 7.4 years old) reported chronic pain (≥three months). The mediation model accounted for 16.3% of anxiety, 17.1% of depression, and 30.9% of pain catastrophizing variances. Pain intensity, insomnia, number of comorbidities, and lifestyle factors (smoking, alcohol consumption, and weight) significantly affected both pain catastrophizing and mood. Anxiety (standardized path coefficient (b_std) = 0.324, p < 0.001) in comparison to depression (b_std = 0.125, p < 0.001) had a greater effect on pain catastrophizing. Mood mediated the relationship between pain catastrophizing and pain-related factors accounting for lifestyle and sociodemographic factors.
