Maintaining resilience over time: A qualitative exploration of the experiences of living with chronic musculoskeletal pain.

BACKGROUND: Living with chronic pain can have several negative consequences. However, some individuals are more resilient despite pain. Although a large body of research exploring resilience-enhancing factors exists, there is a lack of research focused on the changes of individual's resilience over time. OBJECTIVES: This study aims to explore how people with chronic musculoskeletal pain (CMP) describe their experience regarding the maintenance of resilience in the long term. METHODS: Within the framework of the qualitative research strategy, semi-structured interviews and two focus groups with 17 purposefully selected research participants (ages 29-64) were conducted. The data were analysed by integrating thematic analysis and narrative analysis. RESULTS: To maintain resilience in the long term, it is important to take responsibility for one's physical and mental well-being by practicing regular ability-adjusted physical activity, giving up unrealistic expectations, focussing on finding opportunities, not obstacles, maintaining a positive future perspective, and finding significance in life despite experiencing chronic pain. Financial support from the government and access to rehabilitation can facilitate better self-care for those with limited finances. CONCLUSION: This study may be useful for healthcare professionals, psychologists, social workers, and other specialists who daily encounter patients with CMP and aspire to understand the main challenges and needs of this particular group of patients.

The effectiveness of multidisciplinary interventions based on health belief model on musculoskeletal pain in the elderly living in nursing homes: a study protocol for a randomized controlled trial.

BACKGROUND: Due to the burden of musculoskeletal diseases in the elderly and the multifactorial nature of such conditions, controlling the pain caused by these disorders requires multidisciplinary approach. This approach requires the participation of the elderly in applying effective prevention measures. This study aims to design a multidisciplinary educational intervention based on health belief model (HBM) for elderly residents of nursing homes. METHODS: This is a parallel randomized clinical trial among elderly people aged 60 years and over living in a nursing home who suffer from musculoskeletal pain. Eligible participants will be divided into two groups including the intervention group who will receive a multidisciplinary intervention (vitamin D consumption, psycho-social stress management, and physiotherapy) and the control group who will receive usual care. Data collection instruments will include demographic data, the Depression, Anxiety, and Stress Scale (DASS), the visual analogue scale (VAS), and a self-designed questionnaire containing the HBM constructs. The interventions will be carried out by the educational team (general practitioner, psychologist, physiotherapist, and health education specialist). Interventions include changing the wrong beliefs of the elderly, taking 800 units of vitamin D daily, daily walking exercise by the elderly for at least 30 min and maintaining proper body posture during daily activities, muscle relaxation, relaxation techniques, regular exercise, examining their diet and eliminating stimulants (such as smoking and coffee), regular visits with friends and family, and deep breathing techniques. All questionnaires will be completed by the elderly before, after, 3, and 6 months after the intervention. DISCUSSION: The present study will evaluate the effect of an educational intervention based on a multifaceted pain control approach for elderly people who reside in nursing homes in order to reduce musculoskeletal pain in the elderly living in nursing homes. One of the features of this study is its focus on improving the health of elderly residents in nursing homes. Given the increase in the elderly population worldwide, the findings from the current trial might benefit elderly populations. TRIAL REGISTRATION: IRCT20220904055881N1 .

Does pain influence cognitive performance in patients with mild traumatic brain injury?

OBJECTIVES: Pain is still a neglected problem in mild traumatic brain injury (mTBI). In this cross-sectional study, we examined the frequency of musculoskeletal pain in a sample of adult patients with persistent cognitive symptoms after mTBI and whether pain level affected cognition. METHODS: The participants were 23 adult patients aged 18-50 referred to brain injury rehabilitation clinics for neuropsychological assessment after having sustained an mTBI. A non-injured control group (n = 29) was recruited through advertisements. The patients were, on average, assessed 22 months after trauma. All participants completed a comprehensive neuropsychological test battery and completed the Örebro Musculoskeletal Pain Screening Questionnaire, The Rivermead Post-Concussion Symptoms Questionnaire, and the State-Trait Anxiety Inventory. RESULTS: Patients reported high levels of current pain and significantly more frequent neck and shoulder pain than the non-injured controls. Patients also reported high post-concussive symptoms and anxiety levels and performed less well on several neuropsychological tests. Pain level was associated with slower processing speed among the controls but not related to performance in the mTBI group. CONCLUSION: We conclude that musculoskeletal pain is frequent in mTBI patients referred to rehabilitation settings. Furthermore, the results indicate that the interaction between pain and cognitive functioning differs in mTBI compared to controls. Our results implicate that pain screening should be an integrated part of neuropsychological rehabilitation after mTBI to identify conditions that run the risk of becoming chronic. The study was approved by the Regional Ethical Board in Stockholm, Sweden (04-415/2).

Duloxetine and cognitive behavioral therapy with phone-based support for the treatment of chronic musculoskeletal pain: study protocol of the PRECICE randomized control trial.

BACKGROUND: Chronic musculoskeletal pain (CMP) is the most common, disabling, and costly of all pain conditions. While evidence exists for the efficacy of both duloxetine and web-based cognitive behavioral therapy (CBT) as monotherapy, there is a clear need to consider study of treatment components that may complement each other. In addition, given the reported association between patient's adherence and treatment outcomes, strategies are needed to enhance participant's motivation to adopt and maintain continued use of newly learned pain coping skills from CBT. METHODS: Two hundred eighty participants will be recruited from the primary care clinics of a large academic health care system in North Carolina. Participants with CMP will be randomized to one of three treatment arms: (1) combination treatment (duloxetine + web-based self-guided CBT) with phone-based motivational interviewing (MI), (2) combination treatment without phone-based MI, and (3) duloxetine monotherapy. Participants will be in the study for 24 weeks and will be assessed at baseline, week 13, and week 25. The primary outcome is the Brief Pain Inventory (BPI)-Global Pain Severity score, which combines BPI pain severity and BPI pain interference. Secondary measures include between-group comparisons in mean BPI pain severity and BPI pain interference scores. Data collection and outcome assessment will be blinded to treatment group assignment. DISCUSSION: This randomized controlled trial (RCT) will determine if combination treatment with duloxetine and web-based CBT is superior to duloxetine monotherapy for the management of CMP. Furthermore, this RCT will determine the effectiveness of phone-based motivational interviewing in promoting the continued practice of pain coping skills, thereby enhancing treatment outcomes.

Empowering patients with persistent pain: The potential of cognitive functional therapy in interdisciplinary care: A single-case experimental design.

INTRODUCTION AND PURPOSE: Persistent musculoskeletal pain (PMP) is multifactorial and causes both societal and financial burdens. Integration of multifactorial management in patients with PMP remains challenging. A single-case experimental design was performed on three patients suffering from high impact PMP (lumbar spine, shoulder and knee) to i) assess the potential for Cognitive Functional Therapy (CFT) in interdisciplinary care, ii) describe in detail the clinical journey patients experienced during the intervention, and iii) evaluate the changes and associations in relation to the outcome measures of pain, disability, maladaptive movement behavior, subjective overall improvement, health related quality of life and work status. These were monitored over one year, at the end of each of the six intervention modules. RESULTS: After introducing the intervention systematic changes were seen, with medium to large changes (Non-overlap of All Pairs 0.67-1) for all outcome measures. Associations between changes of the outcome measures were large (r ≥ 0.50) and changes occurred concurrently. Minimally clinically important difference thresholds were exceeded for all outcome measures and two patients achieved relevant improvements related to work reintegration. DISCUSSION: The positive results of this study are comparable with recent CFT studies. However, the difference regarding the number of sessions and duration of the intervention is evident. The length of the intervention in this study seemed to enable continuous significant improvements up until 12 months post onset and follow-up. CONCLUSION: CFT in interdisciplinary care was effective for all measures. The detailed descriptions of the clinical processes aim to improve clinical care.

Translation and adaptation of the Arabic version of the injustice experience questionnaire in patients with chronic musculoskeletal pain.

OBJECTIVE: The objectives of this study were to (1) translate the short version of the Injustice Experience Questionnaire (IEQ-SF) from English to Arabic and (2) test the validity and reliability of the translated Arabic version of the IEQ-SF. SUBJECTS AND METHODS: A cross-sectional study in which the original English version of the IEQ-SF was translated into Arabic was conducted in accordance with Beaton's translation process. Internal consistency, reproducibility (retest within 5 days), and validity of the translated Arabic version of the IEQ-SF were tested in Arabic-speaking participants (n = 20). Individuals with chronic pain (n = 99) completed the Arabic versions of the IEQ-SF and the Musculoskeletal Health Questionnaire (MSK-HQ) from June to August 2021. The main analyses included Cronbach's alpha (α), Intraclass Correlation Coefficients (ICC), and Spearman's rank correlations (ρ). RESULTS: The internal consistency (α = 0.74) and test-retest reliability (ICC = 0.88, 0.83-0.92 95% CI) for the translated Arabic version of IEQ-SF were high. There was also a high correlation between the translated Arabic version of the IEQ-SF and different health-related questionnaires such as the MSK-HQ (ρ = -0.738; p < 0.001), Hospital Anxiety and Depression Scale (ρ = 0.701-0.791; all, p < 0.001), and Pain Catastrophizing Scale (ρ = 0.762; p < 0.001). CONCLUSIONS: The Arabic version of the IEQ-SF demonstrated high reliability and validity and would be useful for clinicians and researchers studying Arabic-speaking individuals with chronic pain.

Nocebo expectations rather than placebo expectations affect topical pain relief: A randomized clinical trial.

Patients' expectations and beliefs regarding the potential benefits and harms of medical interventions may induce placebo and nocebo effects, and affect the response to pain therapies. In a randomized clinical trial, we examined the effect of placebo and nocebo expectations on pain relief and adverse events (AEs) in association with a topical treatment among 65 cancer survivors experiencing chronic musculoskeletal pain. Participants received either a 1% camphor-based topical pain patch or a placebo treatment for 14 days. We measured pain severity with the worst pain item of the Brief Pain Inventory (BPI) at baseline and 14 days and treatment expectations at baseline with validated expectation questionnaires. We found that high vs. low nocebo expectations decreased pain severity improvements by 2.5 points (95% confidence interval [CI] -3.8 to -1.2; p<0.001) on a 0-10 numeric rating scale of the BPI and pain response rate by 42.7% (95% CI 0.2-0.6; p<0.001) at day 14, irrespective of placebo expectation status or treatment arms. Patients with high vs. low nocebo expectations in the true arm reported 22.4% more unwanted AEs. High nocebo expectations were associated with increased AEs by 39.5% (odds ratio: 12.0, 95% CI 1.2, 145.5; p=0.029) and decreased pain response in the true arm vs. placebo. Our study demonstrated that nocebo expectations, rather than placebo expectations, elevate the risk of AEs and compromise the effect of topical pain interventions. The findings raise the possibility that nocebo expectations may worsen somatic symptoms through heightening central pain amplification and should be further investigated.

Psychometric properties of the Turkish version of Central Sensitization Inventory-9 in patients with chronic musculoskeletal pain.

The aim of the study was to assess the psychometric properties of the Turkish version of Central Sensitization Inventory-9 (CSI-9) in patients with chronic musculoskeletal pain. The methodological study included 92 patients with chronic musculoskeletal pain. The original version of the CSI-9 was translated and culturally adapted into Turkish. The internal consistency and test-retest reliability were evaluated with Cronbach's α and the intraclass correlation coefficient (ICC), respectively. The assessment of reproducibility was conducted with the standard error of measurement (SEM) and minimal detectable difference (MDD) values. Convergent validity was explored by correlation analysis between the CSI-9 and Central Sensitization Inventory (CSI-25), Brief Pain Inventory (BPI), and European Quality of Life Survey-5 Dimensions (EQ-5D). The structural validity was assessed with factor analysis. Floor and ceiling effects were also analyzed. We found a very good internal consistency (Cronbach's α of 0.83) and excellent test-retest reliability (ICC of 0.96) of the Turkish CSI-9. The SEM demonstrated a range between 0.19 and 1.12, and the MDD was observed to vary from 1.17 to 1.35. The CSI-9 correlated significantly with the CSI-25 ( r  = 0.77, P  < 0.001), the pain severity subscale of the BPI ( r  = 0.41 to 0.53, P  < 0.001), the pain interference subscale of the BPI ( r  = 0.21 to 0.58, P  = 0.02 to P  < 0.001), the EQ-5D ( r  = 0.24 to 0.48, P  < 0.05), and the EQ-5D visual analog scale ( r  = -0.41, P  < 0.001). One factor was identified within the CSI-9. Our data suggest that the Turkish CSI-9 is reliable and valid outcome measure for assessing CS in patients with chronic musculoskeletal pain.

Social support for functional dependence, activity patterns, and chronic pain outcomes: A cross-lagged mediation panel study.

OBJECTIVE: Received social support undermining engagement in life activities of individuals with chronic pain (e.g., solicitousness, support for functional dependence) is consistently correlated with worse physical functioning, pain severity, and disability. Whether such responses lead to worse pain outcomes (operant model of pain) or the latter lead to more supportive responses undermining activity engagement (social communication and empathy models of pain) is unknown, given the lack of cross-lagged panel studies. Furthermore, the mediating role of activity patterns in such relationships over time is entirely unclear. This study aimed to bridge these gaps. METHOD: This was a 3-month prospective study with three waves of data collection (T1-T3; 6-week lag in-between), including 130 older adults (71% women; Mage = 78.26) with musculoskeletal chronic pain attending day-care centers. At every time point, participants filled out self-report measures of staff social support for functional dependence, activity patterns, physical functioning, pain severity, and interference. Scales showed good/very good test-retest reliability (ICC = .74-.96) and internal consistency (all α > .90). RESULTS: Parsimonious cross-lagged panel mediation models showed the best fit (χ²/df < 2.44; CFI > .96; GFI > .93; RMSEA < .09). Bidirectional effects were found over time, but poorer pain outcomes at T1 (higher pain severity/interference, lower physical functioning) more consistently predicted higher social support for functional dependence than vice versa. Poorer pain outcomes (T1) predicted more avoidance/less overdoing (T3), via increased received support for functional dependence (T2). CONCLUSION: Further research on the cyclical relationships between the study variables across chronic pain trajectories is needed to harness the power of interpersonal relationships in future self-management interventions.

Physical and psychosocial work demands associated with pain and disability among skilled male Arab waiters.

BACKGROUND: Physical and psychosocial demands (e.g., serving, cleaning, fulfilling orders) can lead to work-related musculoskeletal pain (WRMSP). OBJECTIVE: To assess the prevalence of WRMSP in the upper quadrant and lower back among skilled male Arab waiters; to evaluate the disability related to WRMSP; to evaluate the association between work demands and WRMSP with related disability. METHODS: 100 skilled male Arab waiters working full-time, aged 18-60, participated in the cross-sectional study. Participants completed basic demographics and working conditions; the NDI; QuickDASH; the OswestryQ; workload, burnout, and job satisfaction at work; the adjusted NordicQ; and the TaskQ, compiled especially for this study. RESULTS: A 12-month pain prevalence, pain frequency, and work avoidance were high: neck- 42%, 60.5%, 89.5%; shoulders -53%, 78.2%, 94.4%; elbows- 46%, 78.6%, 83.3%; lower back- 45%, 44%, 78.7%, respectively. Pain prevalence in at least one site was 83%. The OswestryQ, QuickDASH, and NDI revealed mild-moderate pain and disability (14.85/50, 25.54/75, 13.74/50, respectively). Burnout score was positively associated with OswestryQ, QuickDASH, and NDI. Job satisfaction was negatively associated with 12 months of pain in the lower back, hands, arms, shoulders, and hands (NordicQ). TaskQ was positively associated with OswestryQ. CONCLUSION: Male Arab waiters who work in physically and psychologically challenging conditions report high levels of WRMSP with a high frequency and related work avoidance. Many of them must keep their jobs as they are their families' primary or sole providers. It is possible that they are trying to prevent more severe disabilities in the future by ensuring temporary rest and pain prevention.

Emotion-Focused Psychodynamic Interview for People with Chronic Musculoskeletal Pain and Childhood Adversity: A Randomized Controlled Trial.

Childhood adversity and emotional conflicts are associated with the presence and severity of chronic musculoskeletal pain (CMP), yet common treatments for CMP do not address such risk factors. We developed a single session, emotion-focused psychodynamic interview, based on Emotional Awareness and Expression Therapy and Intensive Short-term Psychodynamic Therapy, and we tested the interview's effects on pain-related outcomes and potential psychological mediators in a randomized, controlled trial. Adults (N = 91; ages 21-70, M = 44.64; 87.9% women) reporting CMP and at least 3 adverse childhood experiences completed measures at baseline and 6-week follow-up. Participants were randomized to immediate interview or waitlist control conditions. The 90-minute interview was conducted via videoconference, and the interviewer elicited disclosure of adversities and conflicts, linked these with pain, and encouraged the experience and expression of adaptive emotions. Analyses indicated that conditions did not differ significantly on change in pain severity; however, compared to control, the interview led to a significantly greater reduction in pain interference (P = .016, ηp2 = .05) and a similar trend for anxiety (P = .058, ηp2 = .04). The interview also significantly changed several potential mediators: pain-related anxiety (P = .008, ηp2 = .06), pain controllability (P = .016, ηp2 = .06), and psychological (P < .001, ηp2 = .15) and brain attributions (P = .022, ηp2 = .05) for pain. Participants viewed the interview as very valuable. We conclude that addressing childhood adversities and conflicts in a psychodynamic interview is beneficial for people with CMP. PERSPECTIVE: This study found that, compared to waitlist control, a 90-minute, remotely-administered, emotion-focused, psychodynamic interview improved pain interference, and anxiety among adults with chronic musculoskeletal pain and childhood adversity. Intensive emotional work can be done in a single session to the benefit of patients with chronic musculoskeletal pain.

Demographic and clinical factors associated with psychological wellbeing in people with chronic, non-specific musculoskeletal pain engaged in multimodal rehabilitation: -a cross-sectional study with a correlational design.

OBJECTIVES: To investigate which demographic and clinical factors were associated with psychological wellbeing in working-aged people in multimodal rehabilitation for musculoskeletal disorders. METHODS: 116 participants met the criteria for inclusion: persistent or intermittent pain for at least three months; pain that adversely impacts daily life; potential for active change despite pain; no co-morbidity or condition that will hinder participation in the rehabilitation program. Primary outcome was psychological wellbeing and independent measures were general, physical and mental health, pain intensity, limitations in daily life, depression and sleep. RESULTS: The results show decreased odds of psychological wellbeing for persons rating high on depression. The results remained significant after adjusting for sex and age. Being a woman increased the odds of high psychological wellbeing. Logistic regression showed that psychological wellbeing was not significantly associated with pain intensity; sleep; functional limitations; general, physical, or mental health. None of the other independent variables was significantly associated with high vs. low psychological wellbeing. CONCLUSIONS: Depression turned out to be significantly related to psychological wellbeing, contrary to pain and limitations in daily life. If further studies with larger, random samples can confirm these results, this knowledge may be important both in clinical settings and in future research.

Effects of a videoconference-based therapeutic exercise intervention on the musculoskeletal pain of eldercare workers: protocol for the ReViEEW randomized controlled trial.

BACKGROUND: Prevalence of musculoskeletal pain is high among eldercare workers, and therapeutic exercise has shown to be effective for its management. Although telerehabilitation is an increasingly used alternative for delivering therapeutic exercise, no studies have assessed synchronous group telerehabilitation interventions for the management of musculoskeletal disorders. Thus, the aim of this article is to describe the protocol of a randomized controlled trial that will assess the effects of a videoconference-based group therapeutic exercise intervention on the musculoskeletal pain of eldercare workers. METHODS: This multicenter trial will randomly assign 130 eldercare workers to either a control or experimental group. Participants in the control group will not receive any intervention, and participants in the experimental group will take part in a 12-week remote supervised videoconference-based intervention, consisting of 2 weekly 45-min group sessions. Each session will include 4 sets of 6 progressive resistance exercises for the lower limbs, upper limbs and trunk, performed with bodyweight and elastic bands at moderate-high intensity. Following the 12 weeks, participants in the experimental group will be provided with material for autonomously carry on the therapeutic exercises and advised to continue performing 2 weekly sessions on their own until a 48-week follow-up. Assessments will be performed at baseline, 12 and 48 weeks. Primary outcome will be average pain intensity in the low back during the last 7 days, measured by the 0-10 Numerical Rating Scale. Secondary outcomes will include additional measures of musculoskeletal pain, psycho-affective state, work-related variables, and physical fitness. DISCUSSION: This will be the first trial, to our knowledge, assessing whether a remote delivery of a group therapeutic exercise intervention via videoconference is effective for reducing the musculoskeletal pain, improving the psycho-affective state and physical fitness, and enhancing the work-related parameters in eldercare workers. If successful, this study will provide innovative tools for implementing effective, scalable and affordable interventions to tackle musculoskeletal disorders in the workplace. It will also highlight the utility of telehealth, and address the importance of therapeutic exercise to manage musculoskeletal pain in a critical population for the future of the aging societies as it is the eldercare workers. TRIAL REGISTRATION: The study protocol was prospectively registered at ClinicalTrials.gov (registration number: NCT05050526) on September 20, 2021.

Understanding Discrepancies in a Person's Fear of Movement and Avoidance Behavior: A Guide for Musculoskeletal Rehabilitation Clinicians Who Support People With Chronic Musculoskeletal Pain.

BACKGROUND: Generic self-report measures do not reflect the complexity of a person's pain-related behavior. Since variations in a person's fear of movement and avoidance behavior may arise from contextual and motivational factors, a person-centered evaluation is required-addressing the cognitions, emotions, motivation, and actual behavior of the person. CLINICAL QUESTION: Most musculoskeletal rehabilitation clinicians will recognize that different people with chronic pain have very different patterns of fear and avoidance behavior. However, an important remaining question for clinicians is "How can I identify and reconcile discrepancies in fear of movement and avoidance behavior observed in the same person, and adapt my management accordingly?" KEY RESULTS: We frame a clinical case of a patient with persistent low back pain to illustrate the key pieces of information that clinicians may consider in a person-centered evaluation (ie, patient interview, self-report measures, and behavioral assessment) when working with patients to manage fear of movement and avoidance behavior. CLINICAL APPLICATION: Understanding the discrepancies in a person's fear of movement and avoidance behavior is essential for musculoskeletal rehabilitation clinicians, as they work in partnership with patients to guide tailored approaches to changing behaviors.

Interdisciplinary Multimodal Pain Rehabilitation in Patients with Chronic Musculoskeletal Pain in Primary Care-A Cohort Study from the Swedish Quality Registry for Pain Rehabilitation (SQRP).

Chronic pain is a major public health issue. Mounting evidence suggests that interdisciplinary multimodal pain rehabilitation programs (IMMRPs) performed in specialist pain care are an effective treatment for patients with chronic pain, but the effects of such treatment if performed in primary care settings have been less studied. The aims of this pragmatic study were to (1) describe characteristics of patients participating in IMMRPs in primary care; (2) examine whether IMMRPs in primary care improve pain, disability, quality of life, and sick leave 1-year post discharge in patients with chronic pain; and (3) investigate if outcomes differ between women and men. Data from 744 (645 women and 99 men, age range 18-65 years) patients with non-malignant chronic pain included in the Swedish Quality Registry for Pain Rehabilitation Primary Care were used to describe patient characteristics and changes in health and sick leave. At 1-year follow-up, the patients had improved significantly (p < 0.01) in all health outcome measures and had reduced sick leave except in men, where no significant change was shown in physical activity level. This study indicates that MMRPs in primary care improved pain and physical and emotional health and reduced sick leave, which was maintained at the 1-year follow-up.

The development and measurement properties of the Dutch version of the fear-avoidance components scale (FACS-D) in persons with chronic musculoskeletal pain.

OBJECTIVES: The Fear-Avoidance Components Scale (FACS) is a recently developed patient-reported instrument assessing different constructs related to the fear-avoidance model of pain. The aim was to translate the original English FACS into Dutch (FACS-D) and assess its measurement properties in persons with chronic musculoskeletal pain. METHODS: The original English FACS (20 item-scale, range: 0-100) was translated in Dutch through standard forward-backward translation methodology. The FACS-D's measurement properties were evaluated in 224 persons with chronic musculoskeletal pain. Internal consistency, test-retest reliability and measurement error were assessed with the Cronbach's alpha coefficient (α), intraclass correlation coefficient (ICC), and standard error of measurement (SEM). Construct validity was assessed through inter-item correlation analyses, exploratory factor analysis, association with other fear-avoidance-related constructs, and hypothesis testing. RESULTS: Internal consistency, test-retest reliability and hypotheses testing were good (α=0.92; ICC=0.92, CI 0.80-0.96; 7/8 hypotheses confirmed). Similar to the original FACS and other translated versions, a two-factor model best fit the data. However, the item distribution differed from other versions. One factor represented "pain-related cognitions and emotions" and a second factor represented "avoidance behaviour." In contrast to the original FACS, low inter-item correlations for item 12 were found. The FACS-D was more strongly associated with fear-avoidance-related constructs of pain severity, perceived disability, feelings of injustice, and depressive/anxiety symptoms than the other fear-avoidance-related scales studied here. CONCLUSIONS: The FACS-D demonstrated good reliability and construct validity, suggesting that it may be a useful measure for Dutch-speaking healthcare providers. Two clinically relevant factors, with a different item distribution than the original FACS, were identified: one covering items on pain-related cognitions and emotions, and one covering items on avoidance behaviour. The stronger association between FACS-D and fear-avoidance related constructs suggests that the FACS-D may be more effective in evaluating the cognitive, emotional and behavioural constructs of pain-related fear-avoidance than other similar measures.

The Portuguese version of the musculoskeletal pain intensity and interference questionnaire for musicians (MPIIQM-Pt): Translation, cultural adaptation, and multicenter validation study in professional orchestra musicians.

OBJECTIVES: We aim to assess the validity and reliability of the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians (MPIIQM) and to add to its cross-cultural adaptation process by translating, culturally adapting, and validating the MPIIQM into European Portuguese language in the population of Portuguese musicians. METHODS: A Portuguese version of the MPIIQM (MPIIQM-Pt) was created through a process of forward and back translation, pilot testing, and cultural adaptation by expert panel evaluation. The psychometric evaluation was performed in a validation sample of 134 musicians, at baseline and after 7 days. RESULTS: The high degree of internal consistency and the substantial test-retest reliability coefficients were demonstrated for each subscale (α = 0.896 and ICC = 0.997 for "pain intensity," and α = 0.879 and ICC = 0.999 for "pain interference," respectively). Exploratory factor analysis indicated two-factor structure (pain intensity and interference) that explained 75.5% of the variance. Both convergent and divergent validity are well demonstrated, confirming more than 90% of the previously defined hypotheses regarding correlations with other measures. DISCUSSION: MPIIQM-Pt is the first validated questionnaire to evaluate pain among Portuguese musicians. It showed excellent psychometric properties, both in terms of internal consistency, test-retest reliability, factor analysis, and construct validity. Therefore, it is a valid and reliable tool suitable for both research and clinical practice purposes. MPIIQM-Pt will allow the development of more robust studies on pain among musicians and the improved assessment and monitoring of pain in this population, filling an important gap in this field of Pain Medicine.

The perceptions of individuals with musculoskeletal disorders towards prognosis: An exploratory qualitative study.

QUESTION(S): How do individuals living with musculoskeletal disorders perceive the concept of prognosis? DESIGN: Exploratory phenomenological study. PARTICIPANTS: Individuals aged 18 years or older currently experiencing a musculoskeletal disorder. DATA ANALYSIS: Single semi-structured one-on-one interviews were conducted. Data was analysed using inductive coding and thematic analysis. RESULTS: Five themes were identified. First, participants defined prognosis as the likely outcome associated with their diagnosis. Their prognosis was often associated with outcomes related to pain, tissue health, and function. Second, participants perceived pain as having a negative impact on their prognosis by limiting their function and having a psychological impact. Third, participants held biomedical views in that tissue health was perceived as a cause for their pain and that tissue healing was essential for pain cessation. It was also difficult for participants to distinguish between pain related to tissue damage, and pain that was not. Fourth, participants use their ability to complete leisure and functional activities to determine the success of their recovery. Finally, participants perceived receiving individual prognoses for pain, tissue health, and function that may be simultaneously occurring as both important and beneficial. CONCLUSION: Overall, participants viewed receiving prognostic information as important and beneficial. When constructing their views on prognosis participants perceived that pain, tissue health, and functional ability could all impact upon prognosis, whilst having a prognosis of their own. Physiotherapists should consider conceptualising and discussing prognosis in terms of pain, tissue health, and function when managing musculoskeletal disorders.
