- Background: Chronic widespread pain (CWP) is common (population prevalence of approximately 10%) and has a significant impact on the individual, healthcare, and society. Currently little is known about the actual course of CWP over time, in particular the pathways to the development and maintenance of CWP. One useful way to understand these pathways is to identify common clusters of people who share pain trajectories. Such information is clinically useful to identify factors that predict development, persistence, and resolution of CWP.Objectives: To identify different longitudinal pain trajectories over a period of 21 years.Methods: A 21-year longitudinal open-population cohort of n=1858 adults (aged 20-74) who completed surveys relating to their pain status in at least three of the five time points 1995, 1998, 2003, 2007, and 2016. Pain status (presence of persistent pain) was ascertained from a report of painful regions (0-18) on a pain mannequin and categorised into: NCP (No chronic pain), CRP (Chronic regional pain) and CWP (chronic widespread pain). Latent Class Growth Analysis (LCGA) was carried out based on these categories. Participants were assigned to a trajectory cluster where the posterior probability was the highest. Model fit was assessed by statistical indices and clinical interpretations of clusters.Results: LCGA identified five clusters describing different pathways of NCP, CRP and CWP over the 21 years. The cluster “Persistent NCP” was the most common pathway (n = 1052, 57%) representing those with no chronic pain over the whole time period. The “Persistent CRP or Migration from CRP to NCP” cluster included 411 individuals (22%) representing a group with stable or improving regional pain. In the groups who were shown to increase pain status, the “Migration from NCP to CRP or CWP” cluster included 92 individuals (5%), and there were 184 individuals (10%) in the cluster “Migration from CRP to CWP” representing a group with regional pain who developed CWP. The final cluster “Persistent CWP” included 119 individuals (6%) representing those with stable CWP throughout the time period. Figure 1 presents the mean number of pain sites over time by cluster.Conclusion: This study showed that whilst half of adults report no chronic pain over 21 years, a substantial proportion develop CWP or have persistent CWP over this time period. Whilst a common trajectory was movement from chronic regional pain to no chronic pain, a pattern of improving CWP was not seen suggesting this is an uncommon trajectory. This is the first study to show long-term trajectories for CWP, and further work is now required to understand factors that may identify individuals at risk of worsening pain status and factors that might promote improvement. These identified pathways of chronic pain over a lifespan improve the understanding of long-term development of chronic pain and chronic widespread pain. © Aili et al. 2019. No commercial re-use.

Markers of stress as predictors of wellbeing and workability
- 2015

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In order to prevent sickness absence and to maintain a safe and sound work climate, interventions may be needed in the workplace. Occupational Health Services (OHS) are special advisers, with the opportunity to suggest/perform interventions at individual and group level. The use of methods for evaluating changes in health is a precondition when assessing that such interventions are meaningful and successful. The aim of this thesis is to study markers of general stress as indicators of changes in the risk of negative health effects, which are feasible when evaluating interventions at group as well as at individual level. Sleep disorders are common in conjunction with stress, and are also associated with negative health effects. Sleep has been investigated in this thesis using: (1) a questionnaire assessing global sleep (during the last six months) (studies I and II); (2) self-reported sleep during one or several specific nights of interest (in a sleep diary) (studies III and IV); (3) objectively measured sleep with an actigraph (study IV). Heart rate variability during sleep is another potential marker, and is examined in study III. Study I and study II are five-year prospective studies investigating sleep as a predictor of: (I) sickness absence in three groups with different pain conditions, and (II) change in number of pain sites between baseline and follow-up. Study III is a cross-sectional twin study investigating self-reported stress during the day and changes in heart rate variability, heart rate and self-reported sleep quality the subsequent night. Further, study III investigated whether individual factors related to genes and/or familial environment had an effect on the associations between stress and heart rate variability/heart rate and stress and self-reported sleep quality. In study IV, repeated objective and subjective sleep measurements during seven consecutive nights were performed. The measurements took place in a workplace, i.e., under conditions translatable to an OHS setting. The number of consecutive measurements that are needed for a reliable sleep measure, and the correlation between subjective and objective sleep measures, are investigated in this study. Sleep disturbances were found to be an indicator of increased risk of sickness absence during five-year follow-up within all the three pain groups that presumably represent three different levels of wellbeing at baseline (study I). Further, sleep was an indicator of change in number of self-reported pain sites between baseline and the five-year follow-up. Associations between perceived daytime stress and changes in heart rate variability, heart rate, and self-reported sleep quality the subsequent night were seen in study III. The results of study III further indicate that these associations are influenced by individual factors related to genes and/or the familial environment. In study IV, it was shown that subjective (sleep quality) and objective (sleep efficiency) measures correlate poorly on a day-by-day basis, which indicates that objective and subjective sleep may capture different dimensions of sleep. If only week nights are included in repeated sleep measurements, fewer measurements are needed to obtain a reliable measure of sleep as compared with when weekend nights are included. In all, measurements of sleep are easier to use than measurements of heart rate variability, which makes sleep a more realistic marker, especially when considering larger groups.

- Background: Chronic widespread pain (CWP) is a common condition (approximately 10% prevalence), that affects women twice as often as men. There is a lack of knowledge in how different coping strategies relates to health status during CWP development in a general population.Objectives: To explore different ways of coping with CWP and to relate the different coping strategies to health-related factors, before and after developing CWP.Methods: A sequential explorative mixed methods study including 19 women 45-67 of age, who had reported CWP in a survey 2016, but not in 1995. Individual interviews were analysed with a phenomenographic approach, and resulted in four categories of coping strategies. These categories were further explored with regard to four dimensions of health status (physical function, bodily pain, vitality and mental health) as measured by SF-36 (0-100, a lower score indicates more disability) and sleep problems measured both in 1995, and 2016.Results: The qualitative analysis revealed four categories representing different coping strategies, where each woman was labelled by the most dominant category; the mastering woman, the persistent woman, the compliant woman and the conquered woman. The first two categories emerged as being active coping strategies, and the latter two as passive. Women with passive strategies reported significantly lower vitality (median 57.5 vs 75, p=0.007) and worse mental health (median 54 vs 93, p=0.021) in 1995, before they had developed CWP compared with those with active coping strategies. No differences were seen between the groups on physical function, bodily pain or sleep.In 2016, there were still a difference between the passive and active group regarding mental health (median 56 vs 80, p=0.022), but not for vitality (median 35 vs 40, p=0.707). No differences were seen between the groups on physical function or bodily pain. All eight women with passive strategies reported problems with sleep in 2016, as compared to 6 of the 11 women with active strategies (p=0.045).Conclusion: Women that reported CWP in 2016, but not in 1995, described both active and passive coping strategies. The qualitative findings were associated with differences in vitality and mental health already in 1995, before they had developed CWP. Further, those with passive coping strategies reported worse health with regard to mental health and sleep problems in 2016. Interestingly, the groups did not differ in bodily pain or physical function neither in 1995 nor in 2016, which implicates the importance for the clinician to take the typical coping strategy into consideration, when meeting these patients in clinical settings. © Aili, Bergman, Bremander, Haglund & Larsson 2019.

- STUDY OBJECTIVES: The aim of the study was to investigate how many nights of measurement are needed for a reliable measure of sleep in a working population including adult women and men.METHODS: In all, 54 individuals participated in the study. Sleep was assessed for 7 consecutive nights using actigraphy as an objective measure, and the Karolinska sleep diary for a subjective measure of quality. Using intra-class correlation and the Spearman-Brown formula, calculations of how many nights of measurements were required for a reliable measure were performed. Differences in reliability according to whether or not weekend measurements were included were investigated. Further, the correlation between objectively (actigraphy) measured sleep and subjectively measured sleep quality was studied over the different days of the week.RESULTS/CONCLUSIONS: The results concerning actigraphy sleep measures suggest that data from at least 2 nights are to be recommended when assessing sleep percent and at least 5 nights when assessing sleep efficiency. For actigraphy-measured total sleep time, more than 7 nights are needed. At least 6 nights of measurements are required for a reliable measure of self-reported sleep. Fewer nights (days) are required if measurements include only week nights. Overall, there was a low correlation between the investigated actigraphy sleep parameters and subjective sleep quality, suggesting that the two methods of measurement capture different dimensions of sleep.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Disturbed sleep and pain often co-exist and the relationship between the two conditions is complex and likely reciprocal. This 5-year prospective study examines whether disturbed sleep can predict the onset of multi-site pain, and whether non-disturbed sleep can predict the resolution of multi-site pain.METHODS: The cohort (n = 1599) was stratified by the number of self-reported pain sites: no pain, pain from 1-2 sites and multi-site pain (≥3 pain sites). Sleep was categorized by self-reported sleep disturbance: sleep A (best sleep), sleep B and sleep C (worst sleep). In the no-pain and pain-from-1-2 sites strata, the association between sleep (A, B and C) and multi-site pain 5 years later was analysed. Further, the prognostic value of sleep for the resolution of multi-site pain at follow-up was calculated for the stratum with multi-site pain at baseline. In the analyses, gender, age, body mass index, smoking, physical activity and work-related exposures were treated as potential confounders.RESULTS: For individuals with no pain at baseline, a significantly higher odds ratio for multi-site pain 5 years later was seen for the tertile reporting worst sleep [odds ratio (OR) 4.55; 95% confidence interval (CI) 1.28-16.12]. Non-disturbed (or less disturbed) sleep had a significant effect when predicting the resolution of multi-site pain (to no pain) (OR 3.96; 95% CI 1.69-9.31).CONCLUSION: In conclusion, sleep could be relevant for predicting both the onset and the resolution of multi-site pain. It seems to be a significant factor to include in research on multi-site pain and when conducting or evaluating intervention programmes for pain.

- Background: Musculoskeletal pain is one of the most common causes of sickness absence. Sleep disturbances are often co-occurring with pain, but the relationship between sleep and pain is complex. Little is known about the importance of self-reported sleep, when predicting sickness absence among persons with musculoskeletal pain. This study aims to study the association between self-reported sleep quality and sickness absence 5 years later, among individuals stratified by presence of lower back pain (LBP) and neck and shoulder pain (NSP). Methods: The cohort (n = 2286) in this 5-year prospective study (using data from the MUSIC-Norrtalje study) was stratified by self-reported pain into three groups: no LBP or NSP, solely LBP or NSP, and oncurrent LBP and NSP. Odds ratios (ORs) for the effect of self-reported sleep disturbances at baseline on sickness absence (> 14 consecutive days), 5 years later, were calculated. Results: Within all three pain strata, individuals reporting the most sleep problems showed a significantly higher OR for all-cause sickness absence, 5 years later. The group with the most pronounced sleep problems within the concurrent LBP and NSP stratum had a significantly higher OR (OR 2.00; CI 1.09-3.67) also for long-term sickness absence (> 90days) 5 years later, compared to the group with the best sleep. Conclusions: Sleep disturbances predict sickness absence among individuals regardless of co-existing features of LBP and/or NSP. The clinical evaluation of patients should take possible sleep disturbances into account in the planning of treatments.

- Background: If localised pain represent one end of a pain spectra, with overall better general health, chronic widespread pain (CWP) and fibromyalgia represent the other end of the spectra with worse general health and more comorbidities with other somatic diseases and mental illness. Sleep problems and fatigue are common among individuals reporting CWP and previous research indicate that sleep problems may be an important predictor for pain prognosis.Objectives: The aim of this population-based study was to investigate if sleep problems and fatigue predict the onset of CWP 5 and 18 years later.Methods: In order to get more stable baseline classifications of CWP, a wash-out period was used, including only individuals who had not reported CWP (according to ACR 1990 criteria for fibromyalgia) at baseline (−98) and three years prior baseline (−95). In all, data from 1249 individuals entered the analyses for the 5 year follow-up (−03) and 791 entered for the 18 year follow-up (−16). Four parameters related to sleep (difficulties initiating sleep, maintaining sleep, early morning awakening and non-restorative sleep), and one parameter related to fatigue (SF-36 vitality scale) were investigated as predictors for CWP. Binary logistic regression analysis were used for analyses.Results: All investigated parameters predicted the onset of CWP five years later (problems with initiating sleep (OR 1.91; 1.16–3.14), maintaining sleep (OR 1.85; 1.14–3.01), early awakening (OR 2.0; 1.37–3.75), non-restorative sleep (OR 2.27; 1.37–3.75) and fatigue (OR 3.70; 1.76–7.84)) in a model adjusted for age, gender, socio-economy and mental health. All parameters except problems with early awakening predicted the onset of CWP also 18 years later. In all, 785 individuals did not report any of the sleeping problems at baseline (fatigue not included), 268 reported one of the problems, 167 two, 128 three and 117 subjects reported to have all four sleep problems. Reporting all four sleep problems was significantly associated with CWP at follow-up at both time points when adjusting for age, gender, socio economy and mental health (OR 4.00; 2.03–7.91 and OR 3.95; 1.90–8.20); adjusting for age, gender, socio economy and number of pain regions (OR 2.94; 1.48–5.82 and OR 2.65; 1.24–5.64) and in a model adjusting for age, gender, socio economy and pain severity (OR 2.97;1.53–5.76; and OR 3.02;1.47–6.21) for the 5 year and 18 year follow-up respectively, compared to not reporting any of the sleep problems at baseline.Conclusions: Both sleeping problems and fatigue predicts the onset of CWP 5- and 18 years later. The results highlight the importance of the assessment of sleep quality in the clinic.

- BackgroundPrevious research suggests that sleep problems may be an important predictor for chronic widespread pain (CWP). With this study we investigated both sleep problems and fatigue as predictors for the onset of CWP over a 5-year and an 18-year perspective in a population free from CWP at baseline.MethodsTo get a more stable classification of CWP, we used a wash-out period, including only individuals who had not reported CWP at baseline (1998) and three years prior baseline (1995). In all, data from 1249 individuals entered the analyses for the 5-year follow-up and 791 entered for the 18-year follow-up. Difficulties initiating sleep, maintaining sleep, early morning awakening, non-restorative sleep and fatigue were investigated as predictors separately and simultaneously in binary logistic regression analyses.ResultsThe results showed that problems with initiating sleep, maintaining sleep, early awakening and non-restorative sleep predicted the onset of CWP over a 5-year (OR 1.85 to OR 2.27) and 18-year (OR 1.54 to OR 2.25) perspective irrespective of mental health (assessed by SF-36) at baseline. Also fatigue predicted the onset of CWP over the two-time perspectives (OR 3.70 and OR 2.36 respectively) when adjusting for mental health. Overall the effect of the sleep problems and fatigue on new onset CWP (over a 5-year perspective) was somewhat attenuated when adjusting for pain at baseline but remained significant for problems with early awakening, non-restorative sleep and fatigue. Problems with maintaining sleep predicted CWP 18years later irrespective of mental health and number of pain regions (OR 1.72). Reporting simultaneous problems with all four aspects of sleep was associated with the onset of CWP over a five-year and 18-yearperspective, irrespective of age, gender, socio economy, mental health and pain at baseline. Sleep problems and fatigue predicted the onset of CWP five years later irrespective of each other.ConclusionSleep problems and fatigue were both important predictors for the onset of CWP over a five-year perspective. Sleep problems was a stronger predictor in a longer time-perspective. The results highlight the importance of the assessment of sleep quality and fatigue in the clinic.

- Background: Approximately ten percent of the population report chronic widespread pain (CWP), the condition is more common among women than men. For most people, the pain interferes with many aspects of every-day life and implies large consequences. However, the group reporting CWP is heterogeneous and there is a need for better understanding of the different strategies used for coping with pain in every-day life.Objectives: The purpose of this study was to describe women’s experiences of how to cope with CWP.Methods: The study had a descriptive design with a qualitative content analysis approach. Individual interviews were conducted with 19 women, 31–66 of age, who had reported CWP in a survey 2016. CWP was defined according to the 1990 ACR criteria for fibromyalgia. To be considered chronic, the pain should have persisted for more than three months during the last 12 months. A manifest qualitative content analysis was used to analyze the main question “How do you cope with your chronic widespread pain?” The analysis resulted in four categories.Results: Women described their coping with CWP in four different ways; to take control, to continue as usual, to follow instructions and to rest. To take control meant to make deliberate decisions to handle everyday day life. It also meant to take care of oneself, to think positive and to exercise at an adequate level. To continue as usual meant not to listen to body signals and either to ignore or accept the pain. To follow instructions meant listening to the health professionals and following advices, but without taking any part of the responsibility for the treatment outcome. To rest meant to perceive an unreasonable need for recovery, to resign and let the pain set the terms for the daily living.Conclusions: Women expressed different ways of coping with CWP including both active and passive strategies. The coping strategies included two dimensions, where one ranged from actively taking control over the pain, to passively following instructions and the other from actively continue as usual by either accepting or ignoring the pain to passively rest and being mastered by pain.

Tidskriftsartikel (refereegranskat)abstract
- Background: Chronic musculoskeletal pain (CMP) is a common cause of disability and impaired quality of life. In Sweden, chronic pain and mental illness are major causes of sick leave. But sick leave itself is also proposed as a risk factor for prolonged sick leave and disability pension.Objectives: To study CMP and sick leave as potential risk factors for long term sick leave or disability pension in a 21 year follow up of a general population cohort.Methods: In a cohort study, with a baseline survey in 1995, 1466 individuals aged 20-67 years were followed for 3 years and 691 for 21 years, or up to the age of 67. CMP (>3 months duration) was reported on a pain mannequin. Sick leave and disability pension were self-reported. Mental health was measured by the mental health (MH) score of the SF-36 health status, and categorized into tertiaries (best, medium and worst). CMP, sick leave, and mental health at baseline, were studied as potential predictors for long term sick leave (disability pension or sick leave >3 months) at a 3 and 21 year follow up. Other potential predictors (socioeconomic group, education, and immigrant status) were introduced in multiple regression analyzes but did not add to the results and were removed from the final models, which were controlled for age and sex.Results: CMP and mental health predicted long term sick leave at the 3 year follow up (OR 2.11, p=0.010 and OR 3.52, p<0.001). Mental health (OR 1.92, p=0.046), but not CMP (OR 0.77, p=0.409), was also a predictor at the 21 year follow up. Sick leave >3 months, irrespectively if due to pain or not, predicted long term sick leave both at the 3 and the 21 year follow up (Table). Sick leave for ≤3 months also predicted long term sick leave at both follow ups when due to pain (OR 2.70, p=0.008 and OR 2.78, p=0.012), but not when due to other causes (OR 1.52, p=0.212 and OR 1.17, p=0.606).Conclusion: Sick leave and especially sick leave due to pain predicted long term sick leave up to 21 years later, independently of pain status or mental health at baseline. It is thus important to early identify individuals at risk and minimize sick leave by providing proper rehabilitation.© Drab, Aili, Haglund & Bergman 2019. No commercial re-use.

Tidskriftsartikel (refereegranskat)abstract
- Background: Modern strategies for knee osteoarthritis (OA) treatment and prevention includes early detection and analyses about pain, gait and lower extremity muscle function including both strength and stability. The very first sign of knee OA is pain or perceived knee instability, often experienced during weight bearing activities e.g. walking. Increased muscle strength will provide dynamic joint stability, reduce pain, and disability. Specific measures of gait symmetry (GS) can be assessed objectively by using accelerometers, which potentially is a feasible method when evaluating early symptoms of symptomatic knee OA.Objectives: The aim was to study if symptoms of early knee pain affected gait symmetry, and the association between lower extremity muscles function and gait symmetry in patients with symptomatic knee OA.Methods: Thirty-five participants (mean age 52 SD 9 years, 66% women) with uni- or bilateral symptomatic knee OA, and without signs of an inflammatory rheumatic disease or knee trauma were included. Pain was assessed by a numeric rating scale (NRS, range 0-10 best to worse), tests of lower extremity muscle function with the maximum number of one leg rises. Dynamic stability was measured as GS by using wearable inertial sensors (PXNordic senseneering platform), during the 6 min walking test to obtain spatio-temporal gait parameters. GS was computed based on stride time (temporal symmetry, TS) and stride length (spatial symmetry, SS). Stride length was normalized by height. Kruskal-Wallis and Spearman’s correlation coefficient were used for analyses.Results: Reports of knee pain did not differ between gender (women 4.7, SD 2.4 vs. men 3.9, SD 2.4, p= 0.362), neither did one leg rises or gait symmetry. Participants who reported unilateral knee pain (left/right side n=9/13), had a shorter stride length on the painful side. The mean difference in stride length was 0.7% of the subject’s height (SD 1.3). Participants with unilateral pain also presented less SS gait than those who reported bilateral pain (p=0.005). The higher number of one-leg rises performed, the better TS was observed. We found a significant relationship between TS and one-leg rise for the right r s =-0.39, p=0.006, and left r s =-0.40, p=0.004 left side). No significant relationship was observed between SS and one-leg rises.Conclusion: Our results is in line with earlier findings stating that knee pain affects GS negatively and that lower extremity muscle function is an important feature for symmetry and dynamic joint stability in patients with symptomatic knee OA. We also found that pain in one leg was related to impaired GS. Bilateral knee pain was however more symmetrical and will need healthy controls for comparison to better understand the negative impact of symptomatic knee OA.

- Background: Chronic widespread pain (CWP) is a major burden to both the person and the community. Non-tumor chronic pain is one of the most common causes for long-term sickness absence in Sweden. The prevalence of CWP in the general population is approximately 10%, and the condition is almost twice as prevalent in women, than in men. Increased understanding of how women with CWP describe triggering factors of pain and pain progress would be of importance when preventing poor pain prognosis, and when customizing the treatment strategy in a setting with person-centered care.Objectives: To explore experiences of factors influencing the progress and severity of pain among women who have developed CWP within the last 21 years.Methods: This is a descriptive study, using a qualitative content analysis with an abductive approach 1 . Nineteen women reporting CWP in a survey 2016, between 45-67 (median 57) years of age, who had not reported CWP in a survey 1995, participated in the study. Data were collected through individual interviews with open-ended questions: “Can you describe how your CWP has developed the last 20 years?”, “How did your CWP change over time?” and “Have you experienced any important events that have influenced the development of your CWP?” Data were analyzed through a manifest qualitative content analysis and six categories emerged.Results: The women described their journey to CWP in terms of triggering, aggravating and consolidating factors. Six different categories emerged; physical strain, emotional strain, social strain, work-related strain, biological strain and environmental strain. Physical strain included strenuous physical activities in leisure time, having muscle tension, inactivity or sleeping problems. Emotional strain included being depressed, worried and stressed, as well as neglecting the pain. Social strain included to prioritize other people before oneself and to meet distrust from the social surroundings. Work-related strain included heavy, monotonous and stressful work but also sedentary work. Biological strain referred to heredity, age and infections. Environmental strain meant that the climate or weather aggravated the pain.Conclusion: The women in the study described how their journey to CWP was influenced by both external and internal strains. The six categories representing different types of strains were recurrent in a context describing triggering, aggravating and consolidating factors. This highlights the complexity of individual pain progress and argues for the importance of person-centred care approaches and rehabilitation programs. The fact that women with CWP feel mistrust from healthcare professionals indicates that the current care approach needs to be changed.

Living every-day life in the shadow of pain or live every-day life with the pain in the shadow – A constant balancing

Tidskriftsartikel (refereegranskat)abstract
- Background: Approximately 10% of the population report chronic widespread pain (CWP), the condition is more common in women than in men. Long-term pain is a public health problem. For most women, the pain interferes with many aspects of every-day life and implies large consequences. Thus, knowledge about how to facilitate life for these women is important.Objectives: To explore women’s experiences of how CWP influence their daily lifeMethods: The study has a latent qualitative content analysis design 1 . Individual interviews were conducted in 19 women 45-67 of age, who had reported CWP in a survey 2016. CWP was defined according to the 1990 ACR criteria for fibromyalgia. Pain that had lasted for more than three months, during the last 12 months, was considered chronic. A latent qualitative content analysis was used to analyze the main questions “Can you describe your experiences of living with CWP?” and “How do the CWP influence your life today?” The interviews were recorded, transcribed verbatim and coded into eight subcategories and three categories; represent the manifest content, and a latent theme exploring the interpreted content of women’s experiences of how CWP influence their every-day life.Results: The interviewed women expressed a life with CWP as “Living every-day life in the shadow of pain or live every-day life with the pain in the shadow” including three categories; the experience of alienation, limitations and plasticity. 1) The experiences of alienation appeared in the subcategories; suspicion and loneliness. Suspicion meant a feeling of not be taken seriously by healthcare and authorities and loneliness meant not being able to participate in social contexts. 2) The experiences of limitations in daily life includes the subcategories; barriers, stress, and dependence of other people. Barriers meant that fatigue limits the activities in every-day life, stress that constitutes limitations in life and dependence on other people’ support. 3) The experiences of plasticity referred to the subcategories resignation, adjustment and resistance. Resignation meant refraining from activities that could affect the pain, such as gardening, walking and dancing. Adjustment were manifested by making the best of the situation, and resistance meant to resist letting the pain set the terms, to give the pain a fight.Conclusion: Women with CWP have to deal with their physical, mental, social and spiritual environment in every-day life. They express a constant balancing in their life between mastering the pain in order to continue living as normal, and allowing the pain to set the terms, i.e. living every-day life in the shadow of pain or live every-day life with the pain in the shadow. Healthcare professionals may consider supporting the patients in finding their individual counterweight to manage life in order to reach better treatment outcome. © Westergården, Aili & Larsson 2019.
