Physical activity and exercise for chronic pain in adults: an overview of Cochrane Reviews

Getting Active Mindfully: Rationale and Case Illustration of a Group Mind-body and Activity Program for Chronic Pain

Chronic pain is associated with substantial decreases in physical and emotional health. Psychosocial and physical restoration interventions, although potentially helpful, typically show small-to-moderate improvements that are limited to the short term, and often exhibit problematic adherence. Here, we present GetActive-Fitbit, a novel 10-week group program that integrates mind-body skills, pain coping and gradual increases in activity reinforced by a commercially available digital monitoring device (Fitbit). We illustrate the program among a group of 4 adults with heterogeneous chronic pain. We also highlight pre to post-program improvements in physical function (objective, performance-based and self-report), emotional function (depression and anxiety) and other relevant outcomes targeted by the program (e.g., pain intensity, catastrophizing, mindfulness, coping, kinesiophobia, emotional support, social isolation, pain resilience, program satisfaction and impression of change). Group participants' experiences suggest that GetActive-Fitbit is credible, useful, and shows potential to improve physical and emotional function among this challenging population.Clinical trial number: NCT03412916.

The aversive value of pain in human decision-making

BACKGROUND

In order to decide between avoiding pain or pursuing competing rewards, pain must be assigned an abstract value that can be traded against that of competing goods. To assess the relationship between subjectively perceived pain and its value, we conducted an experiment where participants had to accept or decline different intensities of painful electric shocks in exchange of monetary rewards.

METHODS

Participants (n = 90) were divided into three groups that were exposed to different distributions of monetary rewards. Monetary offers ranged linearly from $0 to $5 or $10 in groups 1 and 2, respectively, and exponentially from $0 to $5 in group 3. Pain offers ranged from pain detection to pain tolerance thresholds. The value of pain was assessed by identifying the indifference points corresponding to a 50% chance of accepting a certain level of pain for a given monetary reward.

RESULTS

The value of pain increased quadratically as a function of the anticipated pain intensity and was found to be relative to the mean and standard deviation of monetary offers. Moreover, decision times increased as a function of the intensity of accepted painful stimulations. Finally, inter-individual differences in psychological traits related to harm avoidance and persistence influenced the value of pain.

CONCLUSIONS

This is the first demonstration that the value of pain follows a curvilinear function and is relative to the mean and standard deviation of competing monetary rewards. These new observations significantly contribute to our understanding of how pain is assigned value when making decisions between avoiding pain and obtaining rewards.

SIGNIFICANCE

This work provides a description of the pain value function indicating how much people are willing to pay to avoid different intensities of pain. We found that the function was curvilinear, suggesting that the same unit of subjective pain has more value in the high vs. low pain range. Moreover, the pain value was influenced by the experimental manipulation of the rewards distribution and of the inter-individual differences in harm avoidance and persistence. Altogether, the present study provides a detailed account of how subjectively experienced pain is assigned value.

The effects of quality of evidence communication on perception of public health information about COVID-19: Two randomised controlled trials

BACKGROUND

The quality of evidence about the effectiveness of non-pharmaceutical health interventions is often low, but little is known about the effects of communicating indications of evidence quality to the public.

METHODS

In two blinded, randomised, controlled, online experiments, US participants (total n = 2140) were shown one of several versions of an infographic illustrating the effectiveness of eye protection in reducing COVID-19 transmission. Their trust in the information, understanding, feelings of effectiveness of eye protection, and the likelihood of them adopting it were measured.

FINDINGS

Compared to those given no quality cues, participants who were told the quality of the evidence on eye protection was 'low', rated the evidence less trustworthy (p = .001, d = 0.25), and rated it as subjectively less effective (p = .018, d = 0.19). The same effects emerged compared to those who were told the quality of the evidence was 'high', and in one of the two studies, those shown 'low' quality of evidence said they were less likely to use eye protection (p = .005, d = 0.18). Participants who were told the quality of the evidence was 'high' showed no statistically significant differences on these measures compared to those given no information about evidence quality.

CONCLUSIONS

Without quality of evidence cues, participants responded to the evidence about the public health intervention as if it was high quality and this affected their subjective perceptions of its efficacy and trust in the provided information. This raises the ethical dilemma of weighing the importance of transparently stating when the evidence base is actually low quality against evidence that providing such information can decrease trust, perception of intervention efficacy, and likelihood of adopting it.

Effect of Spinal Alignment Changes on Lower Back Pain in Patients Treated with Total Hip Arthroplasty for Hip Osteoarthritis

Background and objectives: The influence of changes in spinal alignment after total hip arthroplasty (THA) on improvement in lower back pain (LBP) remains controversial. To evaluate how changes in spinal malalignment correlate with improvement in preoperative LBP in patients who underwent THA for hip osteoarthritis. Materials and Methods: From November 2015 to January 2017, 104 consecutive patients who underwent unilateral THA were prospectively registered. Whole spine X-rays and patient-reported outcomes (PROs) were obtained preoperatively and 12 months postoperatively. The PROs used were the Numerical Rating Scale (NRS) for back pain, EuroQol 5 Dimension, and Short Form-12. Results: Seventy-four (71%) patients with complete data were eligible for the analysis. The sagittal parameters changed slightly but significantly. Coronal alignment significantly improved. Twenty-six (37%) patients had LBP preoperatively. These patients had smaller lumbar lordosis (LL), larger PT, and larger PI minus LL than the patients without LBP. Fourteen (54%) of the 26 patients with preoperative LBP showed pain improvement, but there were no significant differences in the radiographic parameters. Conclusions: Although preoperative LBP was likely to be resolved after THA, there were no significant correlations between alignment changes and LBP improvement. The cause of LBP in patients with hip osteoarthritis (OA) patients might be multifactorial.

Community-based interventions for chronic musculoskeletal health conditions in rural and remote populations: A systematic review

Chronic musculoskeletal health conditions are highly prevalent in rural and remote areas, globally. It is unknown, however, whether interventions shown to be effective for urban populations are also effective for rural and remote populations. The purpose of the review was to evaluate the effectiveness of community-based interventions for management of chronic musculoskeletal health conditions in rural and remote populations. A systematic review was undertaken of the major databases: Medline, Scopus, Web of Science, Rural and Remote Health, Embase and PEDro to April 2020 with no restrictions on language or publication date. Odds Ratios were calculated to report differences between intervention and control groups. Risk of bias was assessed using the PEDro scale. Meta-analysis was not conducted, given the high heterogeneity among studies. From a total of 3,219 articles identified from the title search, five studies were eligible, with a total of 2,831 participants. Interventions evaluated included education alone, exercise with education and ergonomic modifications. Community-based education and exercise led to significantly reduced chronic musculoskeletal pain [OR = 1.85 (95% CI 1.22, 2.82)] compared with controls. Ergonomic stove installation significantly reduced average prevalence of back pain (0.25% reduction in pain prevalence; p < .05); however, no significant effect [OR = 1.02 (0.63, 1.65)] was found when transformed to Odds Ratio. There were divergent findings for education programmes alone: one study reported a positive effect [OR = 1.78 (1.27, 2.49)], while another reported no significant effect [delivered either in home [OR: 1.21 (0.78, 1.86)] or in small groups [OR = 0.95 (0.60, 1.51)]. A significant improvement in knowledge was found with community-based education delivered in participants' homes [SMD: 1.27 (1.01, 1.54)], in small groups [SMD: 0.79 (0.53, 1.06)], using traditional puppetry [SMD: 4.79 (4.51, 5.06)], and with education and exercise [SMD: 0.29 (0.06, 0.52)]. There is low quality evidence that education and/or exercise improves knowledge of arthritis, and the effectiveness of ergonomic interventions on pain was unclear.

Aerobic exercise with blood flow restriction causes local and systemic hypoalgesia and increases circulating opioid and endocannabinoid levels

This study examined the effect of aerobic exercise with and without blood flow restriction (BFR) on exercise-induced hypoalgesia and endogenous opioid and endocannabinoid systems. In a randomized crossover design, pain-free individuals performed 20 min of cycling in four experimental trials: 1) low-intensity aerobic exercise (LI-AE) at 40% V̇o_2max; 2) LI-AE with low-pressure BFR (BFR40); 3) LI-AE with high-pressure BFR (BFR80); and 4) high-intensity aerobic exercise (HI-AE) at 70% V̇o_2max. Pressure pain thresholds (PPTs) were assessed before and 5 min postexercise. Circulating concentrations of beta-endorphin and 2-arachidonoylglycerol were assessed before and 10 min postexercise. In the exercising legs, postexercise PPTs were increased following BFR40 and BFR80 compared with LI-AE (23-32% vs. 1-2% increase, respectively). The increase in PPTs was comparable to HI-AE (17-20% increase) with BFR40 and greater with BFR80 (30-32% increase). Both BFR80 and HI-AE increased PPTs in remote areas of the body (increase of 26-28% vs. 19-21%, respectively). Postexercise circulating beta-endorphin concentration was increased following BFR40 (11%) and HI-AE (14%), with the greatest change observed following BFR80 (29%). Postexercise circulating 2-arachidonoylglycerol concentration was increased following BFR40 (22%) and BFR80 (20%), with the greatest change observed following HI-AE (57%). Addition of BFR to LI-AE can trigger both local and systemic hypoalgesia that is not observed follow LI-AE alone and activate endogenous opioid and endocannabinoid systems of pain inhibition. Compared with HI-AE, local and systemic hypoalgesia following LI-AE with high-pressure BFR is greater and comparable, respectively. LI-AE with BFR may help pain management in load-compromised individuals.NEW & NOTEWORTHY We have shown that performing blood flow restriction (BFR) during low-intensity aerobic exercise can trigger local and systemic hypoalgesia, which is not typically observed with this intensity of exercise. High-pressure BFR triggers greater and comparable hypoalgesia than high-intensity aerobic exercise in the exercising limbs and remote areas of the body, respectively. Performing BFR during low-intensity aerobic exercise activates the opioid and endocannabinoid systems, providing novel insight into potential mechanisms of hypoalgesia with BFR exercise.

Comprehensive pain management as a frontline treatment to address the opioid crisis

BACKGROUND

The opioid crisis continues to devastate individuals and communities in the United States and abroad. While there have been several measures to address the over-prescription of opioid analgesics, the number of overdose deaths related to prescription opioids has not changed appreciably in the last 10 years. Comprehensive (or multidisciplinary) pain recovery programs consist of providers from multiple backgrounds that treat pain on an individual level through a combination of approaches including physical therapy, emotional and spiritual support, cognitive behavioral therapy, and non-opioid pharmacotherapies. Because there is a dynamic interplay between a given chronic pain patient and multiple providers, comprehensive pain programs are not as "standardized" as other medical treatments because they are meant to meet the individual needs of each patient and their specific pain diagnoses Methods: Review of the literature.

RESULTS

There is evidence that comprehensive pain treatment can reduce pain severity and improve functioning; comprehensive pain treatment can be used to treat those with post-surgical pain, thus preventing the onset of non-medical opioid use and opioid use disorder, and in persons with chronic pain who are on long-term opioid therapy, as a method to reduce or eliminate opioid medication use. Comprehensive pain recovery programs were abundant for a period from the 1960s through the 1980s, but for a variety of reasons, they became financially unsustainable as the national reimbursement environment evolved.

CONCLUSIONS

In the context of the protracted and deadly opioid crisis, revitalizing and expanding comprehensive pain treatment should be considered as a frontline approach to treat chronic pain.

Does adding hip strengthening exercises to manual therapy and segmental stabilization improve outcomes in patients with nonspecific low back pain? A randomized controlled trial

BACKGROUND

The literature is unclear on the need for hip strengthening in persons with low back pain (LBP).

OBJECTIVES

To investigate the effectiveness of hip strengthening exercises when added to manual therapy and lumbar segmental stabilization in patients with chronic nonspecific LBP.

METHODS

Seventy patients with chronic nonspecific LBP were randomly assigned to either the manual therapy and lumbar segmental stabilization group or the manual therapy and lumbar segmental stabilization plus specific hip strengthening group. A 10 cm visual analogue scale and the Rolland-Morris Questionnaire were the primary clinical outcome measures at baseline, at the end of treatment (posttreatment), and 6- and 12-months posttreatment. Hip strength and kinematics were measured as secondary outcomes .

RESULTS

While within-group improvements in pain, disability, and hip extensors strength occurred in both groups, there were no significant between-group differences at posttreatment or follow-ups. Mean difference in changes in pain level between groups at posttreatment and at 6- and 12-month follow-up were 0.5 points (95% confidence interval [CI]: -0.5, 1.5), 0.3 points (95% CI: -0.9, 1.5), and 0.0 points (95% CI: -1.1, 1.1), respectively. The mean differences in changes in disability were 0.8 points (95% CI: -1.3, 2.7), 0.0 points (95% CI: -2.4, 2.4), and 0.4 points (95% CI: -2.0, 2.8), respectively. Finally, we did not observe any between-group differences for any of the other outcomes at any timepoint.

CONCLUSION

The addition of specific hip strengthening does not appear to result in improved clinical outcomes for patients with nonspecific LBP.

The effect of two weeks of spinal manipulative therapy and home stretching exercises on pain and disability in patients with persistent or recurrent neck pain; a randomized controlled trial

Background

Recurrent or persistent neck pain affects a vast number of people globally, leading to reduced quality of life and high societal costs. Clinically, it is a difficult condition to manage, and treatment effect sizes are often moderate at best. Activity and manual therapy are first-line treatment options in current guidelines. We aimed to investigate the combination of home stretching exercises and spinal manipulative therapy in a multicentre randomized controlled clinical trial, carried out in multidiscipline ary primary care clinics.

Methods

The treatment modalities utilized were spinal manipulative therapy and home stretching exercises compared to home stretching exercises alone. Both groups received 4 treatments for 2 weeks. The primary outcome was pain, where the subjective pain experience was investigated by assessing pain intensity (NRS − 11) and the quality of pain (McGill Pain Questionnaire). Neck disability and health status were secondary outcomes, measured using the Neck Disability Indexthe EQ-5D, respectively. One hundred thirty-one adult subjects were randomized to one of the two treatment groups. All subjects had experienced persistent or recurrent neck pain the previous 6 months and were blinded to the other group intervention. The clinicians provided treatment for subjects in both group and could not be blinded. The researchers collecting data were blinded to treatment allocation, as was the statistician performing data analyses. An intention-to-treat analysis was used.

Results

Sixty-six subjects were randomized to the intervention group, and sixty-five to the control group. For NRS − 11, a B-coefficient of − 0,01 was seen, indication a 0,01 improvement for the intervention group in relation to the control group at each time point with a p-value of 0,305. There were no statistically significant differences between groups for any of the outcome measures.

Conclusion

Based on the current findings, there is no additional treatment effect from adding spinal manipulative therapy to neck stretching exercises over 2 weeks for patients with persistent or recurrent neck pain.

Trial registration

The trial was registered 03/07/2018 at ClinicalTrials.gov, registration number: NCT03576846.

A Brief Survey of the COVID-19 Pandemic's Impact on the Chronic Pain Experience

Background

The COVID-19 pandemic has forced sweeping social and behavioral changes that have adversely affected the general population. Many changes, such as business closures, working from home, increased psychological distress, and delayed access to health care, could have unique adverse effects on patients diagnosed with chronic pain (CP). The present study sought to examine perceived changes in the CP experience brought about by the COVID-19 pandemic.

Design

Participants included 487 self-reported patients with musculoskeletal, neuropathic, or postsurgical pain recruited using CloudResearch. A 53-item survey was created to assess changes in perceived pain, mood, control over pain, physical activity, employment, and medical access since the onset of the pandemic.

Results

Results suggested a worsening of the pain experience, particularly for women, with greater pain, negative affect, sedentary functioning, perceived decline in treatment quality, and increased treatment delays. Of note, pandemic-related declines in control over pain, which represents an important clinical target, are associated with other pandemic-related declines and also mediates relevant associations.

Conclusions

For frontline treatment providers, particularly primary care nurses and physicians, these findings may be relevant in order to reduce the likelihood of a worsening of symptoms, loss of self-efficacy regarding management of pain and/or potential maladaptive increase in the use of pain medications.

A randomized controlled trial to evaluate a behavioral economic strategy for improving mobility in veterans with chronic pain

Rates of chronic pain and daily opioid use are higher among veterans relative to civilian populations. Increasing physical activity can reduce pain severity and decrease opioid use among patients with chronic pain. Behavioral economic strategies can improve physical activity levels but have been undertested in veterans with chronic pain. The objective of this study was to evaluate if a financial incentive combined with a loss aversion component-a "regret lottery" in which veterans could win money if they met a set goal or told how much they could have won had they met their goal-would increase physical activity levels among veterans with chronic pain. A 12-week single-blinded randomized controlled trial (ClinicalTrials.gov: NCT04013529) was designed. Veterans with chronic pain (N = 40) receiving care at a specialty pain clinic were eligible for participation, and were randomly assigned (1:1) to either (a) activity trackers and daily text message reminders to increase physical activity ("control arm"), or (b) the same plus a weekly regret lottery ("intervention arm"). For those in the intervention arm, participants who met their activity goal, had a chance to win a small ($30) or large ($100) gift card incentive; those who did not meet their goals were informed of what they would have won had they met their goal. The primary outcome, physical activity, was measured using self-reported physical activity and step counts using activity trackers. Secondary outcomes included changes in physical function, chronic pain severity, depression and opioid use. The sample was primarily white, male and disabled, with an average age of 57 years. No between-arm differences were noted for physical activity, physical function, chronic pain severity, depression or opioid use. Regret lottery-based approaches may be ineffective at increasing physical activity levels in veterans with chronic pain. Trial Registry: NCT04013529.

The effects of blood flow restriction resistance training on indices of delayed onset muscle soreness and peak power

BACKGROUND: Low-load resistance training with blood flow restriction (LL + BFR) attenuated delayed onset muscle soreness (DOMS) under some conditions. OBJECTIVE: The purpose of this study examined the effects of reciprocal concentric-only elbow flexion-extension muscle actions at 30% of peak torque on indices of DOMS. METHODS: Thirty untrained women (mean ± SD; 22 ± 2.4 years) were randomly assigned to 6 training days of LL + BFR (n= 10), low-load non-BFR (LL) (n= 10), or control (n= 10). Participants completed 4 sets (1 × 30, 3 × 15) of submaximal (30% of peak torque), unilateral, isokinetic (120∘s-1) muscle actions. Indices of DOMS including peak power, resting elbow joint angle (ROM), perceived muscle soreness (VAS), and pain pressure threshold (PPT) were assessed. RESULTS: There were no changes in peak power, ROM, or VAS. There was a significant interaction for PPT. Follow-up analyses indicated PPT increased for the LL + BFR condition (Day 5 > Day 2), but did not decrease below baseline. The results of the present study indicated LL + BFR and LL did not induce DOMS for the elbow extensors in previously untrained women. CONCLUSION: These findings suggested LL + BFR and LL concentric-only resistance training could be an effective training modality to elicit muscular adaptation without inducing DOMS.

Promoting physical activity and physical function in people with long-term conditions in primary care: the Function First realist synthesis with co-design

Background

As people age and accumulate long-term conditions, their physical activity and physical function declines, resulting in disability and loss of independence. Primary care is well placed to empower individuals and communities to reduce this decline; however, the best approach is uncertain.

Objectives

To develop a programme theory to explain the mechanisms through which interventions improve physical activity and physical function in people with long-term conditions in different primary care contexts, and to co-design a prototype intervention.

Data sources

Systematic literature searches of relevant databases with forwards and backwards citation tracking, grey literature searches and further purposive searches were conducted. Qualitative data were collected through workshops and interviews.

Design

Realist evidence synthesis and co-design for primary care service innovation.

Setting

Primary care in Wales and England.

Participants

Stakeholders included people with long-term conditions, primary care professionals, people working in relevant community roles and researchers.

Methods

The realist evidence synthesis combined evidence from varied sources of literature with the views, experiences and ideas of stakeholders. The resulting context, mechanism and outcome statements informed three co-design workshops and a knowledge mobilisation workshop for primary care service innovation.

Results

Five context, mechanism and outcome statements were developed. (1) Improving physical activity and function is not prioritised in primary care (context). If the practice team culture is aligned to the elements of physical literacy (mechanism), then physical activity promotion will become routine and embedded in usual care (outcome). (2) Physical activity promotion is inconsistent and unco-ordinated (context). If specific resources are allocated to physical activity promotion (in combination with a supportive practice culture) (mechanism), then this will improve opportunities to change behaviour (outcome). (3) People with long-term conditions have varying levels of physical function and physical activity, varying attitudes to physical activity and differing access to local resources that enable physical activity (context). If physical activity promotion is adapted to individual needs, preferences and local resources (mechanism), then this will facilitate a sustained improvement in physical activity (outcome). (4) Many primary care practice staff lack the knowledge and confidence to promote physical activity (context). If staff develop an improved sense of capability through education and training (mechanism), then they will increase their engagement with physical activity promotion (outcome). (5) If a programme is credible with patients and professionals (context), then trust and confidence in the programme will develop (mechanism) and more patients and professionals will engage with the programme (outcome). A prototype multicomponent intervention was developed. This consisted of resources to nurture a culture of physical literacy, materials to develop the role of a credible professional who can promote physical activity using a directory of local opportunities and resources to assist with individual behaviour change.

Limitations

Realist synthesis and co-design is about what works in which contexts, so these resources and practice implications will need to be modified for different primary care contexts.

Conclusions

We developed a programme theory to explain how physical activity could be promoted in primary care in people with long-term conditions, which informed a prototype intervention.

Future work

A future research programme could further develop the prototype multicomponent intervention and assess its acceptability in practice alongside existing schemes before it is tested in a feasibility study to inform a future randomised controlled trial.

Chronic Pain and Associated Factors Related to Depression among Older Patients in Hanoi, Vietnam

The interaction of chronic pain and depression among older people has been studied for many years. This study aimed to investigate the frequency of chronic pain and depression among older patients and correlated factors. A cross-sectional study was conducted in 921 older patients at the National Geriatric Hospital from November 2019 to March 2020. We used the Charlson Comorbidity Index (CCI) to assess the comorbid condition, a numerical rating scale (NRS) to examine pain severity, and Geriatric Depression Scale-15 items (GDS-15) to measure depression among participants. A chi-square test and Tobit regression were used to analyze the relationships. A total of 921 older patients participated in the study. The proportion of depression accounted for 55.8%. The mean Charlson score and number of diseases were 1.2 and 4.7, respectively. A positive correlation was found between comorbidity and chronic pain and depression. Moreover, socio-demographic variables such as occupation, education, and income were associated with pain and depressive symptoms. This study highlights the issue of mental health in older people with chronic pain. The results indicate the necessity of frequent depression screening, pain management, and social activity programs for older people to enhance their health.

Multimodal Interventions to Improve the Management of Chronic Non-Malignant Pain in Primary Care Using Participatory Research

BACKGROUND

The use of diverse therapies combined with a multidisciplinary approach and prevention initiatives for patients with chronic non-malignant pain (CNMP) can improve health and have a positive impact on psychotropic drug use and the self-management of pain.

PURPOSE

This purpose of this study has been two-fold: to conduct a literature review with a view to selecting best evidence recommendations for CNMP and to prioritize self-care recommendations using a participatory methodology for the analysis and selection of interventions.

METHODS

A qualitative, descriptive, and documentary method based on participatory action research was used.

FINDINGS

Based on the study results, a multimodal psychosocial intervention program has been designed for CNMP that includes psychoeducational therapy, pharmacological therapy, physical exercise, and health assets.

DISCUSSION

The findings are consistent with previous studies underlining the need to invest in resources for the management of CNMP, including strategies for good differential diagnoses and pharmacological treatments combined with non-pharmacological treatments to confer greater well-being for people living with pain who want to participate in their own recovery.

The Impact of the First Wave of the COVID-19 Pandemic on Patients' Perceptions of Chronic Pain

PURPOSE

On 10 March 2020, Greece entered an increasingly restrictive 42-day lockdown, in order to contain the first wave of the COVID-19 pandemic. All scheduled appointments and activities of the pain clinics around the country were postponed indefinitely. The aim of this prospective study was to assess the perceived impact of the first wave of the pandemic on pain, quality of life, and access to treatment, during the first austere lockdown in Greece.

PATIENTS AND METHODS

In this cross-sectional study, 101 patients suffering from chronic pain completed a structured questionnaire. Levels of depression, anxiety, stress, personal wellbeing, optimism and personality traits were also evaluated, using the Depression, Anxiety and Stress Scale (DASS42), the Ten Item Personality Index (TIPI), the Life Orientation Test-Revised (GrLOT-R) and the Personal Wellbeing Index (PWI).

RESULTS

Despite the dramatic decrease in health care visitations before, during and after the imposed lockdown, most patients did not feel that access to pain physicians and medication was significantly affected. Higher levels of stress, anxiety, depression, neuroticism, openness to experience and general satisfaction with life seemed to be important determinant factors in how patients experienced their level, intensity and duration of pain, quality of life and response to medication.

CONCLUSION

The effects of the lockdown had a more severe impact on patients than the pandemic itself. For most, the level of their pain was not affected by the pandemic and was affected only slightly by the lockdown. Quality of life, however, was affected formost participants. Both the necessity and the complications of introducing the use of telemedicine to Greek chronic pain patients became evident during the study.

The effects of race/ethnicity and physician recommendation for physical activity on physical activity levels and arthritis symptoms among adults with arthritis

BACKGROUND

Among U.S. adults with physician-diagnosed arthritis, we examined the association of 1) participant race/ethnicity with meeting physical activity guidelines and arthritis symptoms, and 2) the association of receipt of a physician exercise recommendation with physical activity levels and arthritis symptoms, and whether race/ethnicity moderates these associations.

METHODS

Retrospective, cross-sectional study of National Health Interview Survey pooled data from 2002, 2006, 2009, and 2014 from 27,887 U.S. adults aged ≥18 years with arthritis. Outcomes were meeting aerobic (yes/no) and strengthening guidelines (yes/no), arthritis-associated activity limitations (yes/no) and arthritis-related pain (0-10; higher score = more pain). Predictors were race/ethnicity (White, African American, Latino, and Asian) and receipt of physician recommendation for exercise (yes/no). Covariates included demographic and health characteristics.

RESULTS

Adjusting for covariates, African Americans were more likely (AOR = 1.27; 95% CI 1.12, 1.43) and Asians were less likely (AOR = 0.75; 95% CI 0.61, 0.92) than Whites to meet muscle strengthening activity guidelines. Compared to Whites, African Americans (B = 0.48; 95% CI 0.24, 0.72) and Latinos (B = 0.44; 95% CI 0.15, 0.72) reported more severe, while Asians reported less severe (B = -0.68; 95% CI -1.22, - 0.14) joint pain. Controlling for covariates, physician exercise recommendation was associated with meeting aerobic (AOR = 1.20; 95% CI 1.11, 1.30) and strengthening (AOR = 1.21; 95% CI 1.11, 1.33) guidelines, regardless of race/ethnicity except for a weak negative association with meeting strengthening guidelines (AOR = 0.85; CI 0.74-0.99) among Latinos.

CONCLUSIONS

Disparities in pain exist for African Americans and Latinos with arthritis. Physician exercise recommendation is critical among patients with arthritis to relieve symptom burden.

Depressive Symptoms Associated With Musculoskeletal Pain in Inactive Adults During COVID-19 Quarantine

Background

Depression has been associated with episodes of musculoskeletal pain. However, it is not clear whether such relationships could be mitigated according to the physical activity level.

Aim

To describe, during the COVID-19 pandemic, the relationship between depression and musculoskeletal pain according to the physical activity levels.

Design

Cross-sectional study.

Methods

This research was conducted in Brazil between May 5 and March 17, 2020. Participants (N = 1872; 58% women) were invited through social media to answer a structured online questionnaire. Depressive symptoms were assessed through self-report of perception of depression during quarantine. Musculoskeletal pain was assessed based on the Nordic questionnaire identifying nine possible pain points in the body. Physical activity was assessed based on the weekly frequency, intensity, and duration of each session of physical activity the participants engaged in during COVID-19. The logistic binary regression analyzed the associations between depressive symptoms and musculoskeletal pain according to the participants’ level of physical activity.

Results

Depressive symptoms were associated with pain in six different regions of the body in physically inactive participants. In physically inactive participants, those with depressive symptoms 1.51 (95% CI = 1.04-2.19) and 2.78 (95% CI = 1.81-4.26) times more likely to have pain in one or two and ≥three regions body regions, respectively. In active participants, depressive symptoms were not associated with pain.

Conclusion

During the COVID-19 pandemic, depression was associated with musculoskeletal pain in physically inactive participants.

Aerobic Physical Exercise for Pain Intensity, Aerobic Capacity, and Quality of Life in Patients With Chronic Pain: A Systematic Review and Meta-Analysis

BACKGROUND

Currently, chronic pain is a disabling condition that is difficult to manage, which generates a high burden on health systems. The objective is to determine the effects of aerobic physical exercise in adults with chronic pain.

METHODS

A systematic review of searches in databases including MEDLINE, LILACS, ScienceDirect, PEDro, OTseeker, The Cochrane Library, EBSCO, and Google Scholar was conducted. The search process was carried out until July 31, 2020, and the study selection process was independently carried out through a criteria analysis for each phase. Outcome measures were chosen: aerobic capacity, physical function, quality of life, and pain.

RESULTS

Twenty-seven studies were included in which aerobic exercise was considered as an option to treat chronic pain. These studies showed significant results compared with other treatment options in terms of pain measurements (-0.22 [-0.42 to -0.03]) and aerobic capacity. For quality of life, there were significant improvements in the physical function component over the mental health component evaluated with the short form health survey-36/12.

CONCLUSION

Aerobic exercise is a nonpharmacological therapeutic option for treatment. Also, aerobic capacity and endurance improved when this type of exercise was prescribed, thus resulting in a substantial improvement in the quality of life of people suffering from chronic pain.

Cognitive Change and Relaxation as Key Mechanisms of Treatment Outcome in Chronic Pain: Evidence From Routine Care

Despite effective treatment approaches within the cognitive behavioral framework general treatment effects for chronic pain are rather small to very small. Translation from efficacy trials to naturalistic settings is questionable. There is an urgent need to improve the effectiveness of well-established treatments, such as cognitive-behavior therapy (CBT) and the investigation of mechanisms of change is a promising opportunity. We performed secondary data analysis from routine data of 1,440 chronic pain patients. Patients received CBT in a multidisciplinary setting in two inpatient clinics. Effect sizes and reliable change indices were computed for pain-related disability and depression. The associations between changes in the use of different pain coping skills (cognitive restructuring, activity despite pain, relaxation techniques and mental distraction) and changes in clinical outcomes were analyzed in structural equation models. Pre-post effect sizes range from g = 0.47 (disability) to g = 0.89 (depression). Changes in the use of cognitive restructuring, relaxation and to a lesser degree mental distraction were associated with changes in disability and depression. Effects from randomized trials can be translated to naturalistic settings. The results complement experimental research on mechanisms of change in the treatment of chronic pain and indicate an important role of cognitive change and relaxation as mechanisms of change. Our findings cautiously suggest that clinicians should optimize these processes in chronic pain patients to reduce their physical and emotional disability.

Differences in adaptive and maladaptive psychosocial responses to chronic pain among adults with varying physical activity levels

AIM

Chronic pain is a global public health problem that detrimentally impacts people's health and well-being. Physical activity is beneficial and a recommended self-management strategy for adults living with chronic pain. Yet, many of them struggle to meet the public health recommendation of 150+ minutes/week of moderate-vigorous physical activity. Identifying modifiable factors related to physical activity participation is needed. Adaptive (i.e., self-regulatory efficacy to overcome pain and related barriers [SRE-pain], psychological flexibility) and maladaptive (i.e. pain anxiety) responses were the modifiable factors examined in the present study. The purpose was to investigate whether adults living with chronic pain who were sufficiently active, insufficiently active or inactive significantly differed in their adaptive and maladaptive responses to chronic pain.

METHODS

Adults with self-reported chronic pain for 6+ months (N = 318) completed an online survey that measured physical activity, psychological flexibility, SRE-pain and pain anxiety. Sufficiently active (n = 139), insufficiently active (n = 91) and inactive (n = 88) groups were identified.

RESULTS

A significant multivariate analysis of covariance (MANCOVA) (p < .001) with univariate follow-up tests illustrated that the sufficiently active individuals reported the highest psychological flexibility and SRE-pain compared to insufficiently active and inactive individuals (p's < .001). Overall, sufficiently active participants responded the most adaptively and least maladaptively to their pain, followed by the insufficiently active. Inactive participants responded the most maladaptively.

CONCLUSION

Identifying differences in adaptive and maladaptive responses to pain highlights possible modifiable factors to target in future physical activity intervention research that focuses on improving chronic pain self-management.

A qualitative investigation of activity measurement and change following a mind-body activity program for chronic pain

Increasing activity is important yet challenging among people with chronic pain. Objective assessment of activity using accelerometers (i.e., ActiGraph) has gained popularity, but reactivity to assessment and non-adherence to wearing the ActiGraph may bias data. We explored: 1) experiences of wearing the ActiGraph to identify ways to increase adherence and facilitate accurate assessment of activity; and 2) barriers and facilitators to increasing activity following two mind-body activity programs to optimize future interventions. We conducted semi-structured exit interviews with 13 participants with heterogenous chronic pain who completed a randomized controlled trial of two mind-body activity programs. We analyzed transcripts using a framework approach to generate themes. Participants indicated that receiving reminders increased ActiGraph wear adherence and reported that program skills such as gratitude, pacing, mindfulness, and deep breathing were facilitators to increasing activity, while medical problems were barriers. Interventions aiming to increase activity may benefit from emphasizing mind-body skills and sending ActiGraph wear reminders.

A Retrospective Analysis of Pain Etiology in Middle-Aged Patients with Peripheral Neuropathy

Background and Objectives: Correct assessment and a multidisciplinary approach appear to be extremely important in preventing peripheral neuropathy and its complications. The purpose of this study was to find the correlations and dissimilarities between different types of peripheral neuropathy, the occurrence of pain, and laboratory results. Materials and Methods: This retrospective study assessed 124 patients who were hospitalized in our neurology department due to various types of sensory or motor disturbances. The patients were eventually diagnosed with peripheral neuropathy, based on the electrophysiological study, anamnesis, physical examination, and laboratory results. The whole group was subjected to statistical analysis. Results: The mean age of patients was over 56 years, with a slight woman predominance. A statistically significant (p < 0.05) relationship between the place of residence and gender was seen, where more men than women live in the rural area, while more women than men live in the urban area. Most often we observed symmetric, sensorimotor, demyelinating, inflammatory, and chronic neuropathy. More than 40% of patients reported pain. A statistically significant correlation between the evolution/severity and the occurrence of pain was seen in subacute type (p < 0.05) and small fibre neuropathy (p < 0.01). Conclusions: A higher incidence of peripheral neuropathy in middle-aged people will become essential in the aging society with lifestyle and chronic disorders. Peripheral neuropathy is slightly more common in women than men and its occurrence may be influenced by work performed or internal and external factors. In the study group, more than 40% of patients reported pain, therefore the pain measurement for each patient should be implemented and repeated at every visit. An assessment of sodium level and, in women, markers of neuroinflammation level in the various types of peripheral neuropathy may be an interesting direction for the future.

Effect of aerobic water exercise during pregnancy on epidural use and pain: A multi-centre, randomised, controlled trial

OBJECTIVE

The physical and psychological benefits of exercise during pregnancy are well established. However, the impact of exercise on pain during labour and the use of epidural analgesia has been less explored. The main aim of this study was to analyse the effectiveness and safety of moderate aerobic water exercise by pregnant women on the subsequent use of epidural analgesia during labour, induction of labour, mode of delivery, and pain perception.

DESIGN

A multi-centre, parallel, randomised, evaluator blinded, controlled trial in a primary care setting.

SETTING

Primary care centres in a health district of a tertiary obstetric metropolitan hospital in Mallorca, Spain.

PARTICIPANTS

Pregnant women (14 to 20 weeks' gestation) who had low risk of complications.

METHODS

Three hundred and twenty pregnant women were randomly assigned to two groups: women who practiced moderate aquatic aerobic exercise with usual antenatal care, and those who received usual prenatal care alone. The gynaecologist, anaesthesiologist and midwife who assisted the women during labour were blinded to group allocations. Principal outcome: use of epidural analgesia during labour. Other outcomes: use of epidural analgesia before 6 cm cervical dilation, labour pain, type of delivery, time of active labour, episiotomy or perineal tear, and induction of labour.

RESULTS

The exercise program did not affect the use of epidural analgesia (OR = 0.79, 95% CI = 0.44 to 1.40), vaginal delivery (OR = 1.35, 95% CI = 0.73 to 2.41), or caesarean section (OR = 0.94, 95% CI = 0.47 to 1.89). However, women in the exercise group reported less pain during labour (mean difference: -0.6, 95% CI = -1.11 to -0.09). The two groups (moderate aquatic aerobic exercise versus usual antenatal care) showed no significant differences in maternal or newborn adverse events.

CONCLUSION

Aquatic aerobic exercise during pregnancy had no effect on the use of epidural analgesia during labour, whereas pain perception was lower after aquatic exercise compared to usual care in pregnancy. The intervention was safe for pregnant women and their newborns.

'Function First': how to promote physical activity and physical function in people with long-term conditions managed in primary care? A study combining realist and co-design methods

OBJECTIVES

To develop a taxonomy of interventions and a programme theory explaining how interventions improve physical activity and function in people with long-term conditions managed in primary care. To co-design a prototype intervention informed by the programme theory.

DESIGN

Realist synthesis combining evidence from a wide range of rich and relevant literature with stakeholder views. Resulting context, mechanism and outcome statements informed co-design and knowledge mobilisation workshops with stakeholders to develop a primary care service innovation.

RESULTS

A taxonomy was produced, including 13 categories of physical activity interventions for people with long-term conditions.

ABRIDGED REALIST PROGRAMME THEORY

Routinely addressing physical activity within consultations is dependent on a reinforcing practice culture, and targeted resources, with better coordination, will generate more opportunities to address low physical activity. The adaptation of physical activity promotion to individual needs and preferences of people with long-term conditions helps affect positive patient behaviour change. Training can improve knowledge, confidence and capability of practice staff to better promote physical activity. Engagement in any physical activity promotion programme will depend on the degree to which it makes sense to patients and professions, and is seen as trustworthy.

CO-DESIGN

The programme theory informed the co-design of a prototype intervention to: improve physical literacy among practice staff; describe/develop the role of a physical activity advisor who can encourage the use of local opportunities to be more active; and provide materials to support behaviour change.

CONCLUSIONS

Previous physical activity interventions in primary care have had limited effect. This may be because they have only partially addressed factors emerging in our programme theory. The co-designed prototype intervention aims to address all elements of this emergent theory, but needs further development and consideration alongside current schemes and contexts (including implications relevant to COVID-19), and testing in a future study. The integration of realist and co-design methods strengthened this study.

Can dogs and cats really help our spinal cord stimulation patients?

OBJECTIVES

Pet ownership has been shown to decrease morbidity and mortality in several aspects of health but has not been studied in chronic pain patients. We evaluate whether subjects who underwent spinal cord stimulation (SCS) and own a pet have improved outcomes compared to non-pet owners.

METHODS

After obtaining IRB approval, we re-contacted 38 subjects who underwent SCS surgery with preoperative and 1-year postoperative data on Numerical Rating Scale (NRS), McGill Pain Questionnaire (MPQ), Oswestry Disability Index (ODI), Beck Depression Inventory (BDI), and Pain Catastrophizing scale (PCS). We examined influence of pets and pet ownership-specific behaviors on improvement in SCS outcomes.

RESULTS

Patients included 24 males/14 females with a mean age of 59.9 ± 11.5 years. At mean follow-up of 12.2 months (range 10-14), there were improvements in NRS, ODI, BDI, PCS and MPQ. Twenty subjects owned pets and 18 did not; all believed pet ownership could improve health. Pet owners improved more on NRS-right now (p = 0.05) and BDI (p = 0.05), and were more satisfied with SCS (p = 0.04). No significant improvement was seen in ODI, MPQ, or PCS. However, PCS did improve in pet owners who exercised their pet (PCS-total, p < 0.01; PCS-helplessness, p < 0.01; PCS-rumination, p = 0.05; PCS-magnification, p = 0.02).

CONCLUSIONS

We provide preliminary evidence that pet ownership is associated with improved pain, depression and SCS satisfaction. Exercising with a pet also appears to be beneficial in limiting pain catastrophizing. Pets show promise as a novel means to improve patient SCS outcomes.

Pain in Veterans with COPD: relationship with physical activity and exercise capacity

BACKGROUND

Pain is a common but underappreciated symptom experienced by people with Chronic Obstructive Pulmonary Disease (COPD). The relationships between pain and physical activity (PA) and exercise capacity are poorly understood.

METHODS

This retrospective secondary analysis includes three cohorts of Veterans with COPD who participated in longitudinal studies evaluating PA and exercise capacity with objective measures of daily step counts and 6-min walk test (6MWT) distance, respectively. Pain was assessed using the bodily pain domain of the Veterans RAND-36. In two cohorts, participants were randomly assigned to a web-based, pedometer-mediated PA intervention which has previously been demonstrated to improve PA.

RESULTS

Three-hundred and seventy-three (373) unique study participants were included in this analysis. Eighty-three percent (n = 311) of the population reported at least mild pain and/or at least a little bit of interference due to pain at baseline. Cross-sectionally, greater bodily pain was associated with lower 6MWT distance (β = 0.51; 95% CI 0.20, 0.82; p = 0.0013). Longitudinally, worsening bodily pain was associated with a decline in 6MWT distance (β = 0.30; 95% CI 0.03, 0.58; p = 0.0312). There was no association between baseline bodily pain and baseline daily step counts, baseline bodily pain and change in PA, or change in bodily pain and change in PA. Compared to usual care, our PA intervention improved bodily pain scores (β = 6.17; 95% CI 1.84, 10.45; p = 0.0054). Bodily pain scores did not affect the impact of the intervention on daily step counts.

CONCLUSION

Pain is highly prevalent and significantly associated with lower exercise capacity among Veterans with COPD. Worsening pain co-occurred with decline in exercise capacity but not PA. Our intervention reduced pain, although pain did not affect the impact of the intervention on PA.

Effects of a progressive resistance exercise program in patients with hand osteoarthritis: A randomized, controlled trial with a blinded assessor

OBJECTIVE

To assess the effectiveness of a progressive resistance strength program on pain, function and strength in hand osteoarthritis patients.

DESIGN

Randomized controlled trial.

SETTINGS

Outpatients, University Hospital.

SUBJECTS

Sixty hand osteoarthritis patients were randomly allocated to exercise group (n = 30) or control group (n = 30).

INTERVENTION

The exercise group performed a progressive resistance strength program for hand muscles over 12 weeks. Both groups had a single education session.

MAIN MEASURES

The primary outcome was pain intensity (numeric pain scale). The secondary outcomes were - AUSCAN Hand Osteoarthritis Index, Cochin Hand Functional Scale for function and grip and pinch strength. A blinded evaluator performed the evaluations at baseline, 6 and 12 weeks.

RESULTS

The mean age were 68.9 (8.8) and 64.7 (8.9) for control and exercise groups, respectively. No significant differences between-group was observed for pain after 12 weeks (mean difference between groups was -1.30 (-0.02 to 2.62) for dominant hand and -1.33 (0.01-2.65) for non-dominant hand at T12, with P = 0.085 and 0.295, respectively). Regarding secondary outcomes, statistically significant differences between groups were found in exercise group: AUSCAN index - total score (P = 0.005), pain (P = 0.006), function (P = 0.047), and Cochin scale (P = 0.042) with the following mean difference between groups: -9.9 (4.07-15.73), -3.26 (1.06-5.46), -5.03 (1.20-8.86), and -6.27 (0.18-12.36), respectively.

CONCLUSION

No difference was observed for pain (numerical pain scale) after the progressive resistance exercise program performed, however in exercise group, an improvement was observed on secondary outcomes such as pain during activities and function for patients with hand osteoarthritis.

Left to themselves: Time to target chronic pain in childhood rare diseases

BACKGROUND

Chronic pain is prevalent among patients with rare diseases (RDs). However, little is understood about how biopsychosocial mechanisms may be integrated in the unique set of clinical features and therapeutic challenges inherent in their pain conditions.

METHODS

This review presents examples of major categories of RDs with particular pain conditions. In addition, we provide translational evidence on clinical and scientific rationale for psychosocially- and neurodevelopmentally-informed treatment of pain in RD patients.

RESULTS

Neurobiological and functional overlap between various RD syndromes and pain states suggests amalgamation and mutual modulation of the respective conditions. Emotional sequelae could be construed as an emotional homologue of physical pain mediated via overlapping brain circuitry. Given their clearly defined genetic and molecular etiologies, RDs may serve as heuristic models for unraveling pathophysiological processes inherent in chronic pain.

CONCLUSIONS

Systematic evaluation of chronic pain in patients with RD contributes to sophisticated insight into both pain and their psychosocial correlates, which could transform treatment.

Pain Management of Amazon Indigenous Peoples: A Community-Based Study

Purpose

Indigenous peoples are vulnerable populations that live in remote areas of the Amazon forest with limited access to health-care services. Underreporting and undertreatment of pain is a common event in the general population but little is known about these issues in indigenous peoples. The aim of this study was to investigate the characteristics and cultural aspects of pain management in five ethnicities of the Brazilian Amazon.

Materials and Methods

Cross-sectional study carried out with adult indigenous individuals from five ethnicities of the Brazilian Amazon over two scientific expeditions (June–July/2017 and February–March/2019). Pain assessment included etiology, intensity, duration, aggravating and alleviating factors, body location, impact of pain on activities of daily living, and treatment.

Results

Ninety indigenous individuals with a mean age of 41.42 ± 19.59 years (range 19‒98 years) and median age of 37 years participated in the study. Sixty-four individuals (71.1%) reported experiencing pain at the time of interview with intermittent musculoskeletal pain of strong intensity being the more prevalent (back pain: 45.3%, joint pain: 43.7%) followed by headache (26.5%). The main alleviating factors reported were traditional indigenous medicine (21.0%) and rest (30.0%), and physical exertion was the main aggravating factor (69.0%). Most study participants reported that pain affected their mood, activities of daily living, and sleep and that they used both traditional indigenous medicine (78.0%) and conventional medicine (81.0%) for pain relief.

Conclusion

Musculoskeletal pain is prevalent among indigenous individuals, affects their quality of life, and is partly attributed to their lifestyle. Cultural aspects mediating the pain experience were observed. Traditional indigenous medicine for pain relief remains partially preserved among the ethnic groups investigated. The findings of this study can help improve the delivery care to these vulnerable populations.

Perception of musculoskeletal pain in the state of confinement: associated factors

OBJECTIVE

to describe the perception of musculoskeletal pain in the population and how the state of confinement (adopted as a measure to control contagion by COVID-19) has interfered with it, as well as identifying the sociodemographic, occupational, physical, and psychosocial factors involved.

METHOD

an observational, cross-sectional and analytical study, with simple random probabilistic sampling, aimed at residents in Spain over 18 years old during the confinement period. An ad hoc survey was conducted, consisting in 59 items.

RESULTS

a total of 3,247 surveys were answered. Persistent musculoskeletal pain or significant episodes thereof increased 22.2% during confinement. The main location was the spine (49.5%). The related factors were decreased physical activity, increased seated position, and use of electronic devices. The psychological impact of confinement was also related to the perception of musculoskeletal pain.

CONCLUSION

the state of confinement causes an increase in the perception of musculoskeletal pain. The identification of a particularly sensitive population profile, as well as that of the related factors, allows establishing multidisciplinary approaches in health promotion.

Evaluation of clinical practice guidelines (CPG) on the management of female chronic pelvic pain (CPP) using the AGREE II instrument

Introduction and hypothesis

Variations in guidelines may result in differences in treatments and potentially poorer health-related outcomes. We aimed to systematically review and evaluate the quality of national and international guidelines and create an inventory of CPG recommendations on CPP.

Methods

We searched EMBASE and MEDLINE databases from inception till August 2020 as well as websites of professional organizations and societies. We selected national and international CPGs reporting on the diagnosis and management of female CPP. We included six CPGs. Five researchers independently assessed the quality of included guidelines using the AGREE II tool and extracted recommendations.

Results

Two hundred thirty-two recommendations were recorded and grouped into six categories: diagnosis, medical treatment, surgical management, behavioural interventions, complementary/alternative therapies and education/research. Thirty-nine (17.11%) recommendations were comparable including: a comprehensive pain history, a multi-disciplinary approach, attributing muscular dysfunction as a cause of CPP and an assessment of quality of life. Two guidelines acknowledged sexual dysfunction associated with CPP and recommended treatment with pelvic floor exercises and behavioural interventions. All guidelines recommended surgical management; however, there was no consensus regarding adhesiolysis, bilateral salpingo-oophorectomy during hysterectomy, neurectomy and laparoscopic uterosacral nerve ablation. Half of recommendations (106, 46.49%) were unreferenced or made in absence of good-quality evidence or supported by expert opinion. Based on the AGREE II assessment, two guidelines were graded as high quality and recommended without modifications (EAU and RCOG). Guidelines performed poorly in the “Applicability”, “Editorial Independence” and “Stakeholder Involvement” domains.

Conclusion

Majority of guidelines were of moderate quality with significant variation in recommendations and quality of guideline development.

Does the Addition of Pain Neurophysiology Education to a Therapeutic Exercise Program Improve Physical Function in Women with Fibromyalgia Syndrome? Secondary Analysis of a Randomized Controlled Trial

Therapeutic exercise (TE) is one of the most investigated approaches for the management of FMS. Pain neurophysiology education (PNE) helps toward understanding the pain condition, leading to maladaptive pain cognitions and coping strategies in patients with chronic pain. Our study aimed to assess the effects of therapeutic exercise and pain neurophysiology education versus TE in isolation on fatigue, sleep disturbances, and physical function in the short term and at three months of follow-up in women with fibromyalgia syndrome (FMS). A single-blind randomized controlled trial was carried out. A total of 32 women with FMS referred from medical doctors and fibromyalgia association were randomized in 2 groups: PNE + TE group or TE group. Fatigue and sleep disturbances (Visual Analog Score) and physical function (Senior Fitness Test) were assessed before, after intervention, and at three months of follow-up. Significant improvements were achieved in the Timed Up and Go test (p = 0.042) and Arm Curl test (p = 0.043) after intervention and on handgrip in the non-dominant side at three months of follow-up (p = 0.036) on the PNE + TE group. No between-groups differences were found for fatigue, sleep disturbances, and the rest of test included in the Senior Fitness Test. In conclusion, these results suggest that PNE + TE appears to be more effective than TE in isolation for the improvement of physical function (Timed Up and Go test and Arm Curl test) in women with FMS in the short term.

Patients want their doctors' help to increase physical activity: a cross sectional study in general practice

BACKGROUND

Inactivity is prevalent in patients presenting in general practice, and the health benefits of increased physical activity (PA) are well known. Few studies have explored whether patients want their general practitioner's (GPs) contribution in facilitating a lifestyle change.

OBJECTIVE

To identify the characteristics of patients who expect help from their doctor in increasing levels of PA.

DESIGN

We collected data via questionnaires for this cross-sectional study from general practices.

SETTING

General practices in Norway, during Spring 2019.

SUBJECTS

A total of 2104 consecutive patients (response rate 75%) participated.

MAIN OUTCOME MEASURES

The questionnaire included questions about self-rated health, level of physical activity, the desire to become more physically active, and questions about the role of the GP in increasing the level of physical activity in their patients. We analysed our data using Pearson chi-square and binary logistic regression.

RESULTS

Female patients were less active, but their motivation to increase activity and their expectations of receiving help from their doctor were similar to males. Younger patients were more motivated for increased activity, and to manage without help from their doctors. Impaired self-rated health (SRH) was associated with inactivity and, at the same time, with the motivation to become more active with help from general practitioners.

CONCLUSION

Most patients in the GPs' office are physically inactive. This study revealed an important message for GPs: in clinical work, emphasise physical activity for health gains, especially for patients with impaired SRH.Key PointsFour out of five patients attending Norwegian general practice are inactiveMore than 85% of these patients want to increase their physical activity levelMore than 50% would like help from their GP to achieve this goal.

Chronic pain: an update on burden, best practices, and new advances

Chronic pain exerts an enormous personal and economic burden, affecting more than 30% of people worldwide according to some studies. Unlike acute pain, which carries survival value, chronic pain might be best considered to be a disease, with treatment (eg, to be active despite the pain) and psychological (eg, pain acceptance and optimism as goals) implications. Pain can be categorised as nociceptive (from tissue injury), neuropathic (from nerve injury), or nociplastic (from a sensitised nervous system), all of which affect work-up and treatment decisions at every level; however, in practice there is considerable overlap in the different types of pain mechanisms within and between patients, so many experts consider pain classification as a continuum. The biopsychosocial model of pain presents physical symptoms as the denouement of a dynamic interaction between biological, psychological, and social factors. Although it is widely known that pain can cause psychological distress and sleep problems, many medical practitioners do not realise that these associations are bidirectional. While predisposing factors and consequences of chronic pain are well known, the flipside is that factors promoting resilience, such as emotional support systems and good health, can promote healing and reduce pain chronification. Quality of life indicators and neuroplastic changes might also be reversible with adequate pain management. Clinical trials and guidelines typically recommend a personalised multimodal, interdisciplinary treatment approach, which might include pharmacotherapy, psychotherapy, integrative treatments, and invasive procedures.

Health outcomes among detoxification patients: The role of chronic pain

Understanding associations between chronic pain and health outcomes among detoxification patients may help improve treatment outcomes and abstinence rates. Exercise is a modifiable lifestyle factor that may reduce the effect of pain on outcomes in this population. The current study examined whether baseline pain, exercise, and their interaction were associated with psychiatric and medical severity, and abstinence self-efficacy, over six months following detoxification. Participants were veteran patients in alcohol or opioid detoxification treatment (N = 298) who were followed for six months (91.1%). Psychiatric severity and abstinence self-efficacy improved over the six months after detoxification; medical severity was stable. More intense pain at baseline was associated with poorer psychiatric and medical outcomes during the post-detoxification period. Regular exercise at baseline was associated with less psychiatric severity and more abstinence self-efficacy during the post-detoxification period. A significant pain by exercise interaction at baseline indicated that regular exercise was associated with more abstinence self-efficacy during the post-detoxification period only among participants with less intense pain. Pain by exercise interactions was not significant for the outcomes of psychiatric and medical severity. Among detoxification patients, exercise may be beneficial in improving outcomes among those with less intense pain.

Improving Outpatient Management of Patients On Chronic Opioid Therapy

Managing patients with chronic pain on chronic opioid therapy (COT) can be challenging if done mainly by an individual clinician. A stepwise, systematic approach to managing patients on COT includes centering the discussion around safety for the patient. Treatment agreements and monitoring plans are important to safe prescribing. With a team-based care approach programs can be implemented, which optimize the benefits of opioid therapy and mitigate the risk. In these settings COT can be prescribed adhering to current guidelines in order to help achieve pain management, optimize function, and advance the patients' quality of life goals.

Development of a Novel Mind-Body Activity and Pain Management Program for Older Adults With Cognitive Decline

BACKGROUND AND OBJECTIVES

Chronic pain (CP) and cognitive decline (CD) often co-occur in older adults, which can reinforce a "disability spiral." Early interventions teaching pain coping skills and gradual increases in activity (walking) are needed to promote overall well-being and potentially delay further decline of cognition and daily functioning. The goal of this mixed-methods study was to guide the development of two mind-body activity programs for CP and CD which focus on increasing walking using time goals (Active Brains) or step count reinforced by a Fitbit (Active Brains-Fitbit).

RESEARCH DESIGN AND METHODS

Older adults with CP and CD (N = 23) participated in a one-time focus group (four total) and completed measures of physical, emotional, and cognitive functioning. Qualitative analyses identified population-specific needs, preferences, and perceptions of proposed program skills. Quantitative analysis compared clinical characteristics to population norms and explored intercorrelations among treatment targets.

RESULTS

Thematic analyses revealed six main themes: (1) challenges living with CP and (2) CD, (3) current walking, (4) technology (Fitbit) to increase walking, (5) perceptions of proposed program skills (e.g., mind-body, pain, and increased walking), and (6) program barriers and facilitators. Quantitative analyses showed that (a) participants had physical function below reference values and (b) higher self-efficacy correlated with higher cognitive, emotional, and physical functioning.

DISCUSSION AND IMPLICATIONS

Focus group participants were enthusiastic about the proposed program skills. Current work includes open pilot testing, qualitative interviews, and a small randomized controlled trial to optimize the programs and methodology in preparation for efficacy testing against an educational control.

Should Exercises be Painful or not? Effects on Clinical and Experimental Pain in Individuals with Shoulder Pain

Exercise can reduce pain, however the effect of painful versus non-painful exercises is uncertain. The primary aim of this randomized crossover study was to compare the effect of painful versus nonpainful isometric shoulder exercises on pain intensity after exercise in individuals with rotator cuff-related shoulder pain. Secondary exploratory aims were to describe the effects on pressure pain thresholds (PPTs), conditioned pain modulation (CPM) and muscle strength. On separate days, 35 individuals performed painful isometric shoulder exercises (external rotation; 20% above pain threshold), nonpainful isometric shoulder exercises (external rotation; 20% below pain threshold), and a rest condition, in randomised order. Shoulder pain intensity, PPTs, CPM, and external rotation strength were assessed before, immediately after and 45 minutes after conditions. No significant differences were observed between painful and nonpainful exercises. Visual analogue scale scores increased immediately after both painful and non-painful exercises compared with rest (P = .047, partial ƞ² = .07), but were similar to preexercise levels after 45 minutes. No changes in PPTs, CPM, or muscle strength after exercises compared with rest were observed. Painful and non-painful isometric exercises caused a moderate but short-lasting increase in shoulder pain in individuals with RCRSP. Isometric exercises had no effect on pain sensitivity and shoulder muscle strength or CPM. Perspective: This study evaluated for the first time in individuals with rotator cuff-related shoulder pain the effects of painful versus non-painful isometric exercises on different pain-related outcome measures. Both painful and non-painful isometric exercises caused a moderate but relatively short-lasting increase in shoulder pain in individuals with rotator cuff-related shoulder pain. Trial registration number: (ClinicalTrials.gov) NCT03675399.

Auricular Acupuncture to Facilitate Outpatient Opioid Weaning: A Randomized Pilot Study

Objective: The purpose of this study was to integrate acupuncture within the standard of care during outpatient opioid tapering and assess impact of this treatment on cumulative withdrawal symptoms, psychologic distress, and pain. Methods: This prospective randomized controlled pilot study administered the National Acupuncture Detoxification Association protocol following monthly opioid tapering. A total of 9 participants were randomized into the intervention group and compared with 6 participants who underwent the standard of care for outpatient opioid tapering. All providers prescribing medication management to both groups were blinded. Psychologic distress was evaluated using the hospital anxiety and depression scale (HADS). The clinical institute narcotic assessment (CINA) measured subjective withdrawal symptoms and pain was assessed using the numerical rating scale (NRS). Results: Overall anxiety appeared slightly higher in the acupuncture group (HADS 7.0 compared with 6.5), however, depression was lower when compared with the standard of care group (HADS 4.0 compared with 6.5). The standard of care group reported more intense withdrawal symptoms (CINA 9.0 compared with 3.5) as well as higher pain scores (NRS 6.5 compared with 5.0). There were no statistically significant differences among the standard of care and acupuncture groups. Conclusions: This study suggests that auricular acupuncture may be implemented within the standard of care for patients undergoing outpatient opioid weaning regimens. Although results were not statistically significant, they support future research and reveal a promising expansion of treatment options for patients physically dependent on opioid medication.

Therapeutic Effectiveness of AxioBionics Wearable Therapy Pain Management System in Patients with Chronic Lower Back Pain

Chronic lower back pain is one of the most common medical conditions leading to a significant decrease in quality of life. This study retrospectively analyzed whether the AxioBionics Wearable Therapy Pain Management (WTPM) System, a customized and wearable electrical stimulation device, alleviated chronic lower back pain, and improved muscular function. This study assessed self-reported pain levels using the visual analog scale before and during the use of the AxioBionics WTPM System when performing normal activities such as sitting, standing, and walking (n = 69). Results showed that both at-rest and activity-related pain were significantly reduced during treatment with the AxioBionics WTPM System (% reduction in pain: 64% and 60%, respectively; P < .05). Thus, this study suggests that the AxioBionics WTPM System is efficacious in treating chronic lower back pain even when other therapies have failed to sufficiently decrease reported pain levels.

Lower levels of physical activity are associated with pain progression in older adults, a longitudinal study

BACKGROUND

While pain is common in older adults, the association with physical activity remains unclear. Currently, the role physical activity plays in impacting pain developing over time is not well defined.

METHODS

Latent transition analysis (LTA) is a model-based approach to identifying underlying subgroups in a population, longitudinally, based on measured characteristics. In this study, LTA was used to explore the associations between physical activity levels and pain classes of adults aged over 50 years, from the Irish Longitudinal Study on Ageing (n = 8,175) across three waves of data collection (4 years).

RESULTS

Using three previously established pain classes (No Pain; Low-Moderate Impact Pain; High Impact Pain), 66% of older adults were classified as having 'No Pain' across the three waves. At Wave 1, individuals reporting low (OR = 4.00, 95% CI [3.21, 5.17]) or moderate (OR = 1.59, 95% CI [1.27, 1.99]) levels of physical activity are more likely to be in the High Impact Pain class, than the No Pain class. Longitudinally, individuals in the No Pain class with low or moderate physical activity were more likely to transition to the High Impact Pain class compared to those with higher physical activity scores (from Wave 1 to Wave 2, OR = 1.90, 95% CI [1.15, 3.37]; and from Wave 2 to Wave 3, OR = 2.27, 95% CI [1.40, 4.74]).

CONCLUSION

Older adults who do not meet minimum physical activity guidelines for moderate intensity exercise are at increased risk of higher impact pain when followed over 4 years.

SIGNIFICANCE

Older adults who do not meet minimum physical activity guidelines are at increased risk of transitioning to higher impact pain classes when followed over 4 years.

Treatment targets of exercise for persistent non-specific low back pain: a consensus study

OBJECTIVES

Despite several hundred previous randomised controlled trials (RCTs), the key treatment targets of exercise for persistent non-specific low back pain (NSLBP) remain unclear. This study aimed to generate consensus about the key treatment targets of exercise interventions for patients with NSLBP.

DESIGN

Consensus was generated using modified nominal group technique in two, sequential, workshops. The results of a previous systematic review informed the first, national, workshop idea generation and the results of this workshop informed the second, international, workshop. The authors generated a starting list of 30 treatment targets from the systematic review. A pre-specified consensus threshold of 75% was used in the voting stage.

PARTICIPANTS

Workshop participants included people with experience of using exercise to manage their persistent NSLBP, clinicians who prescribe exercise for persistent NSLBP, and researchers who design and evaluate exercise interventions in RCTs. All participants generated, voted and ranked the treatment targets in each workshop using an online platform.

RESULTS

A total of 39 participants contributed to the consensus (15 in the national workshop and 24 in the international workshop), comprising two people with NSLBP, six clinicians and 31 researchers/clinicians. A total of 40 exercise treatment targets were generated, and 25 were retained after voting and ranking. The prioritised targets of exercise for persistent NSLBP were: improving function, improving quality of life, reducing pain, meeting patient-specific goals and reducing fear of movement.

CONCLUSIONS

Future RCTs of exercise should specify the targets of their exercise intervention and consider assessing these treatment targets as well as including mediation analyses.

The effects of age-related macular degeneration on quality of life in a Brazilian population

BACKGROUND

To evaluate the impact of age-related macular degeneration (AMD) on the quality of life (QoL) in a Brazilian population using The National Eye Institute-Visual Function Questionnaire-25 (NEI-VFQ-25).

METHODS

This observational study included 462 participants from the Departments of Ophthalmology of the University of Campinas and Conderg-Divinolândia. The NEI-VFQ-25 questionnaire and Rasch analysis were used to assess the vision-related quality of life (VRQoL). Patients with macular neovascularization were interviewed at enrollment and after three loading doses of intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment.

RESULTS

One hundred thirty-three patients were excluded because they had another ophthalmic disease, for a total of 349 patients included in the study (177 in the AMD group, 172 in the control group; 56.4% were women; mean ± standard deviation age, 70.6 ± 9.5 years). Most NEI-VFQ-25 subscale scores were significantly lower in the AMD group compared with the control group. The Rasch-calibrated NEI-VFQ-25 median score in the visual-functioning component was 56.41 for the AMD group and 61.53 for the control group, a difference of ± 4.00 (P = 0.0001). Separate analyses of the sociodemographic and ocular characteristics showed that the NEI-VFQ-25 scores were affected mostly by family income, educational level, descent, diet (vegetables/fruits), physical activity, and visual acuity (VA). The longitudinal component assessed a different group of 48 patients with exudative disease treated with anti-VEGF drugs. The mean logarithm of the minimum angle of resolution change in VA in treated eyes was a 0.16 decrease (P = 0.01). The mean change in the optical coherence tomography macular thickness was a 36.74-μm decrease (P = 0.012) from baseline to 4 months. The mean NEI-VFQ-25 scores improved significantly from baseline to follow-up at 4 months in almost all subscales.

CONCLUSIONS

In a Brazilian community, patients with AMD had a worse VRQoL than controls. The AMD severity and bilaterality were associated with decreased NEI-VFQ-25 scores. Higher family income, educational level, descent, and lifestyle significantly improved several subscales of the NEI-VFQ-25 questionnaire. Treated patients with exudative AMD had improvements in the VA, macular thickness, and most NEI-VFQ-25 subscale scores.

Telerehabilitation for Pain Management

Telerehabilitation for pain management uses communication technology to minimize geographic barriers. Access to such technology has proven critically important during the coronavirus disease-2019 pandemic and has been useful for patients with chronic pain disorders unable to travel. The evaluation and treatment of such disorders requires a whole health approach that individualizes treatment options and delivers care through a biopsychosocial approach. The goals of care are unchanged from an in-person patient-provider experience. Telerehabilitation can be successfully implemented in pain management with appropriate consideration for staging an evaluation, a structured approach to the visit, and application of standard clinical metrics.

Region-specific Exercises vs General Exercises in the Management of Spinal and Peripheral Musculoskeletal Disorders: A Systematic Review With Meta-analyses of Randomized Controlled Trials

OBJECTIVE

To compare the efficacy of region-specific exercises to general exercises approaches for adults with spinal or peripheral musculoskeletal disorders (MSKDs).

DATA SOURCES

Electronic searches were conducted up to April 2020 in Medline, Embase, Cochrane Central Register of Controlled Trials, and Cumulative Index to Nursing and Allied Health.

STUDY SELECTION

Randomized control trials (RCTs) on the efficacy of region-specific exercises compared to general exercises approaches for adults with various MSKDs.

DATA EXTRACTION

Mean differences and standardized mean differences were calculated using random-effects inverse variance modeling. Eighteen RCTs (n=1719) were included. Cohorts were composed of participants with chronic neck (n=313) or low back disorders (n=1096) and knee osteoarthritis (OA) (n=310).

DATA SYNTHESIS

Based on low-quality evidence in the short-term and very low-quality in the mid- and long-term, there were no statistically significant differences between region-specific and general exercises in terms of pain and disability reductions for adults with spinal disorders or knee OA. Secondary analyses for pain reduction in the short-term for neck or low back disorders did not report any statistically significant differences according to very low- to low-quality of evidence.

CONCLUSIONS

The difference in treatment effect remains uncertain between region-specific and general exercises approaches. Based on very low- to low-quality evidence, there appear to have no differences between both types of exercise approaches for pain reduction or disability for adults with spinal disorders. Future trials may change the current conclusions. More evidence is needed for region-specific exercises compared to general exercises for other peripheral MSKDs including knee OA.

The 4-Element Movement System Model to Guide Physical Therapist Education, Practice, and Movement-Related Research

The movement system has been adopted as the key identity for the physical therapy profession, and recognition of physical therapists' primary expertise in managing movement dysfunction is an important achievement. However, existing movement system models seem inadequate for guiding education, practice, or research. Lack of a clear, broadly applicable model may hamper progress in physical therapists actually adopting this identity. We propose a model composed of 4 primary elements essential to all movement: motion, force, energy, and control. Although these elements overlap and interact, they can each be examined and tested with some degree of specificity. The proposed 4-element model incorporates specific guidance for visual, qualitative assessment of movement during functional tasks that can be used to develop hypotheses about movement dysfunction and serve as a precursor to more quantitative tests and measures. Human movement always occurs within an environmental context and is affected by personal factors, and these concepts are represented within the model. The proposed scheme is consistent with other widely used models within the profession, such as the International Classification of Functioning, Disability and Health and the Patient Management Model. We demonstrate with multiple examples how the model can be applied to a broad spectrum of patients across the lifespan with musculoskeletal, neurologic, and cardiopulmonary disorders.
