What is known and what is still unknown within chronic musculoskeletal pain? A systematic evidence and gap map

Co-creating a Choosing Wisely leaflet supporting the reduction of imaging usage in low back pain management - A multi-method study

OBJECTIVE

The objective was to co-create an information resource in the form of a leaflet, to be distributed in clinical settings, websites or social media targeting people with low back pain.

METHODS

This multi-method study was conducted in four stages: literature search, input from practice consultants, program theory development, and think-aloud interviews with people experiencing low back pain. Each stage was followed by a consensus meeting in which the steering group refined the leaflet based on the emerging knowledge.

RESULTS

The literature search highlighted patients' need for easy-to-understand information about their back pain diagnosis, management strategies, social activities, work and solutions for supported self-management strategies. Practice consultants emphasized concise, relatable content. The program theory identified potential mechanisms for content creation, development, and implementation of the leaflet, such as addressing patient concerns, reducing diagnostic uncertainty, insights into management options, and validation. Think-aloud interviews with 18 people living with low back pain informed the iteration of the leaflet, enhancing language clarification and content comprehension.

CONCLUSIONS

We co-created a new Choosing Wisely leaflet, created with end-users in mind, specifically focused on reducing unnecessary imaging for low back pain.

PRACTICE IMPLICATIONS

This leaflet may support clinical settings in delivering evidence-based approaches and supporting self-management.

Shouldering Our Way Into a More Meaningful Research Agenda for Atraumatic Shoulder Pain: A Priority Setting Study

OBJECTIVE: To amplify the voices of people living with atraumatic shoulder pain, their relatives, and health care practitioners, and to establish research questions. DESIGN: A priority-setting study using a modified approach originally formulated by the James Lind Alliance (JLA). METHODS: The process consisted of 6 phases (initiation, consultation, collation, prioritization, validation, and reporting), and included 2 e-surveys and 2 separate virtual workshops. We included people with atraumatic shoulder pain, relatives, health care practitioners managing shoulder pain, and researchers conducting research within the field. RESULTS: Six hundred and eight people participated (n = 383 [63%] patients, n = 213 [35%] health care practitioners, and n = 12 [2%] carers). In the first survey, 297 participants submitted 1080 potential research questions, which were collated into 16 main themes and 94 subthemes and transformed into research questions. These research questions were featured in the second survey, where 290 participants prioritized the questions, resulting in a compilation of the top 25 questions. Based on discussions from 2 separate online workshops with a total of 21 participants, a top-10 list was created. CONCLUSION: In the final priority list, the 3 research questions with the highest ranking were, first, "how can we improve the translation of research into clinical practice?"; second, "how can we prevent atraumatic shoulder pain?"; and third, "who benefits from surgery, and who does not?"

Global and regional trends and projections of chronic pain from 1990 to 2035: Analyses based on global burden of diseases study 2019

Background

Chronic pain poses a significant public health challenge. We present the global and regional data on Prevalence, Incidence and Years Lived with Disability (YLDs) for Chronic pain from the Global burden of disease (GBD) study 2019 data and analyze their associations with Socio-demographic index (SDI), age, and gender, and the future trends from 2020 to 2035.

Methods

Regional trends in the burden of chronic pain and its association with age, gender, and SDI were assessed from 1990 to 2019. Joinpoint analysis was employed to describe trends in chronic pain burden across different SDI regions. Additionally, the Bayesian Age-Period-Cohort model (BAPC) was used for predicting future trends. Age-standardized rates (ASRs) of prevalence, incidence, and YLDs were employed to quantify the burden of chronic pain.

Results

Between 1990 and 2019, a significant increase was observed in global prevalence and YLDs rates of chronic pain. Higher rates were found among females, whereas a faster rise was noted among males. Notably, Low Back Pain (LBP) and Migraine accounted for predominant YLDs globally, particularly among those aged 75 and above. A notable prevalence of Tension-type Headache (TTH) was observed among younger populations. Furthermore, ASRs for chronic pain were highest in high-SDI regions. Projections suggest an increase in headache ASRs globally for both genders from 2020 to 2035.

Conclusion

From 1990 to 2019, the global burden of chronic pain increased significantly, with projections indicating a continued rise in headache burden over the next 15 years, underscoring the need for heightened attention to these issues.

Adolescent and Parent Experiences and Perceived Effectiveness of Physical Interventions for Chronic Musculoskeletal Pain: A Qualitative Study

INTRODUCTION

There is a paucity of evidence on the effectiveness of physical interventions for chronic musculoskeletal pain affecting adolescents. This study explored adolescent and parent experiences and perceived effectiveness of physical intervention for chronic musculoskeletal pain in the UK.

METHODS

Using semi-structured interviews, 21 young people receiving treatment for chronic musculoskeletal pain and 21 parents were interviewed regarding their healthcare experiences. Data regarding experiences of physical interventions were analysed in this secondary qualitative analysis using inductive reflexive thematic analysis.

RESULTS

Three themes that captured why adolescents and parents perceived physical interventions to be effective or not were (1) feeling in control, (2) the right person and an explanation that makes sense and (3) make a difference to me not my foot.

DISCUSSION

Core concepts that appeared to influence the perceived effectiveness of physical interventions from the perspectives of adolescents and parents included facilitating adolescent autonomy, establishing a therapeutic alliance on the basis of trust and focusing physiotherapy treatment on meaningful participation in life.

CONCLUSION

There were no ideal physical interventions. The themes convey the importance of therapeutic alliance, intervention context and the need for personalised care.

Developing attributes and attribute-levels for subacromial pain syndrome: A systematic review and qualitative study

BACKGROUND

Subacromial pain syndrome (SAPS), the most common cause of shoulder pain, can be treated through different treatments with similar effects. Therefore, in terms of deciding on the right treatment fit, patient preferences need to be understood. We aimed to identify treatment characteristics that delineate interventions (attributes) and corresponding sets of specific categorical range (attribute-levels) for SAPS.

METHODS

This multiple method study systematically reviewed both qualitative and quantitative studies on patient preferences for treatment of SAPS, which informed semi-structured interviews with 9 clinicians and 14 patients. The qualitative data from the interviews was analyzed using the framework analysis formulated by Ritchie and Spencer. Attributes and attribute levels of the systematic review and interviews were summarized and categorized.

RESULTS

The search resulted in 2607 studies, 16 of which met the eligibility criteria. The review identified 120 potential attributes, which were synthesized into 25 potential attributes. Fourteen new potential attributes were identified through the interviews, equaling a total of 39 attributes across 11 categories. Levels for 37 attributes were identified through systematic review and interviews, we were unable to identify levels for 2 attributes.

CONCLUSIONS

This study identified attributes and attribute levels for the treatment of SAPS. There was a discrepancy in the frequency of the represented attributes between the literature and interviews. This study may improve the understanding of patient preferences for the treatment of SAPS and help individualize care. Our study informs a future discrete choice experiment and supports shared decision-making in clinical practice.

Understanding the importance of therapeutic alliance during physiotherapy treatment for musculoskeletal pain in children: a scoping review

Introduction

Musculoskeletal pain affecting children is common. Rehabilitation and treatment effectiveness can be influenced by multiple individual and contextual factors. The need for more rigorous evaluation of physiotherapy treatment for children's pain, identification of the role of specific techniques, and exploration of the influence of the therapeutic alliance is needed. This scoping review of research aimed to examine: (1) What are the perceptions of children, parents, and physiotherapists about the importance of therapeutic alliance during musculoskeletal pain treatment? (2) What are the key characteristics of therapeutic alliance during a child's musculoskeletal pain treatment from the perspectives of children, parents, and physiotherapists? and (3) What are the perceived impacts of therapeutic alliance (positive and negative) during a child's physiotherapy treatment for musculoskeletal pain?

Methods

The scoping review, based on Arksey and O'Malley's framework and reporting was guided by PRISMA-ScR. The search strategy was based on three concept blocks: (1) Study population: Children (<18 years); (2) Medical condition: Any musculoskeletal pain (acute, chronic primary, chronic secondary); (3) Intervention: Qualitative exploration of experience of physiotherapy treatment delivered by a physiotherapist from the perspective of a child, parent, or physiotherapist. The search (no date limit) was conducted in February 2024 across Medline, AMED and CINAHL.

Results

Following duplicate removal and assessment of eligibility of the initial 236 articles, nine articles were included; of these, only one specifically aimed to explore therapeutic alliance and it was the only paper to directly mention therapeutic alliance. All nine articles presented the child's experience. One overarching theme "Finding resilience within me through therapeutic alliance" and three main themes: "A trusted guide through the ups and the downs of rehabilitation"; "Having a route map"; and "Take me seriously but make it fun" were identified.

Discussion

Therapeutic alliance was considered important by children, parents and physiotherapist and it influenced child and parent perceptions of physiotherapy and overall treatment outcomes. Physiotherapists can foster the children's resilience when experiencing musculoskeletal pain by providing disciplinary expertise, connecting and collaborating with the child by becoming their trusted guide, and co-creating a route map for rehabilitation by helping them to learn about their body, pain and recovery timeline.

Development and internal validation of a multivariable prognostic model to predict chronic pain after a new episode of non-specific idiopathic, non-traumatic neck pain in physiotherapy primary care practice

OBJECTIVE

To develop and internally validate a prognostic model to predict chronic pain after a new episode of acute or subacute non-specific idiopathic, non-traumatic neck pain in patients presenting to physiotherapy primary care, emphasising modifiable biomedical, psychological and social factors.

DESIGN

A prospective cohort study with a 6-month follow-up between January 2020 and March 2023.

SETTING

30 physiotherapy primary care practices.

PARTICIPANTS

Patients with a new presentation of non-specific idiopathic, non-traumatic neck pain, with a duration lasting no longer than 12 weeks from onset.

BASELINE MEASURES

Candidate prognostic variables collected from participants included age and sex, neck pain symptoms, work-related factors, general factors, psychological and behavioural factors and the remaining factors: therapeutic relation and healthcare provider attitude.

OUTCOME MEASURES

Pain intensity at 6 weeks, 3 months and 6 months on a Numeric Pain Rating Scale (NPRS) after inclusion. An NPRS score of ≥3 at each time point was used to define chronic neck pain.

RESULTS

62 (10%) of the 603 participants developed chronic neck pain. The prognostic factors in the final model were sex, pain intensity, reported pain in different body regions, headache since and before the neck pain, posture during work, employment status, illness beliefs about pain identity and recovery, treatment beliefs, distress and self-efficacy. The model demonstrated an optimism-corrected area under the curve of 0.83 and a corrected R2 of 0.24. Calibration was deemed acceptable to good, as indicated by the calibration curve. The Hosmer-Lemeshow test yielded a p-value of 0.7167, indicating a good model fit.

CONCLUSION

This model has the potential to obtain a valid prognosis for developing chronic pain after a new episode of acute and subacute non-specific idiopathic, non-traumatic neck pain. It includes mostly potentially modifiable factors for physiotherapy practice. External validation of this model is recommended.

Cross-cultural adaptation and validation of the Mental Health Quality of Life (MHQoL) questionnaire in a Chinese-speaking population with chronic musculoskeletal pain

BACKGROUND

The Mental Health Quality of Life (MHQoL) questionnaire is concise and suitable for rapid assessment of CMP (chronic musculoskeletal pain) patients in primary care. However, there is a lack of Chinese versions of the MHQoL.

OBJECTIVE

To cross-culturally translate the MHQoL into Chinese and to assess its psychometric properties in Chinese-speaking patients with CMP.

METHODS

The MHQoL was translated into Chinese according to the International Guidelines for the Cross-Cultural Adaptation of Self-Report Measures. 171 CMP patients were recruited to receive the Chinese versions of the MHQoL, SF-36, and HADS tests, and the MHQoL was retested seven days later.

RESULT

The Chinese version of MHQoL had good retest reliability (MHQoL-7D: ICC = 0.971; MHQoL-VAS: ICC = 0.988) and internal consistency (Cronbach's alpha = 0.829). It showed a moderate correlation with the SF-36 total score (r=-0.509); the MHQoL-VAS moderately correlated with the Hospital Anxiety Depression Scale (r=-0.548). The MHQoL-7D showed no correlations with the SF-36's PF (r=-0.083) and BP (r=-0.170), weak correlations with RP (r=-0.284), RE (r=-0.298), and SF (r=-0.380), and moderate-to-strong correlations with GH (r=-0.638), VT (r=-0.480), and MH (r=-0.632).

CONCLUSION

The Chinese version of the MHQoL can be used in clinical practice and research in Chinese-speaking CMP patients.

Improving Rehabilitation Research to Optimize Care and Outcomes for People with Chronic Primary Low Back Pain: Methodological and Reporting Recommendations from a WHO Systematic Review Series

Chronic primary low back pain (CPLBP) is a prevalent and disabling condition that often requires rehabilitation interventions to improve function and alleviate pain. This paper aims to advance future research, including systematic reviews and randomized controlled trials (RCTs), on CPLBP management. We provide methodological and reporting recommendations derived from our conducted systematic reviews, offering practical guidance for conducting robust research on the effectiveness of rehabilitation interventions for CPLBP. Our systematic reviews contributed to the development of a WHO clinical guideline for CPLBP. Based on our experience, we have identified methodological issues and recommendations, which are compiled in a comprehensive table and discussed systematically within established frameworks for reporting and critically appraising RCTs. In conclusion, embracing the complexity of CPLBP involves recognizing its multifactorial nature and diverse contexts and planning for varying treatment responses. By embracing this complexity and emphasizing methodological rigor, research in the field can be improved, potentially leading to better care and outcomes for individuals with CPLBP.

The influence of cultural and religious factors on cross-national variations in the prevalence of chronic back and neck pain: an analysis of data from the global burden of disease 2019 study

Introduction

Low back pain and neck pain are among the most commonly reported forms of chronic pain worldwide, and are associated with significant distress, disability and impairment in quality of life. Though these categories of pain can be analyzed and treated from a biomedical perspective, there is evidence that they are both related to psychological variables such as depression and anxiety. The experience of pain can be significantly influenced by cultural values. For example, cultural beliefs and attitudes can influence the meaning attached to the experience of pain, the responses of others to a sufferer's pain, and the likelihood of seeking medical care for particular symptoms. Likewise, religious beliefs and practices can influence the both experience of pain and the responses to it. These factors have also been associated with variations in the severity of depression and anxiety.

Methods

In the current study, data on the estimated national prevalence of both low back pain and neck pain, obtained from the 2019 Global Burden of Disease Study (GBD 2019), is analyzed in relation to cross-national variations in cultural values, as measured using Hofstede's model (n =115 countries) and in religious belief and practice, based on the most recent Pew Research Center survey (n = 105 countries). To address possible confounding factors, these analyses were adjusted for variables known to be associated with chronic low back or neck pain, namely smoking, alcohol use, obesity, anxiety, depression and insufficient physical activity.

Results

It was found that the cultural dimensions of Power Distance and Collectivism were inversely correlated with the prevalence of chronic low back pain, and Uncertainty Avoidance was inversely correlated with the prevalence of chronic neck pain, even after adjustment for potential confounders. Measures of religious affiliation and practice were negatively correlated with the prevalence of both conditions, but these associations were not significant after adjusting for cultural values and confounders.

Discussion

These results highlight the existence of meaningful cross-cultural variations in the occurrence of common forms of chronic musculoskeletal pain. Psychological and social factors that could account for these variations are reviewed, along with their implications for the holistic management of patients with these disorders.
