Self-report and device-based physical activity measures and adherence to physical activity recommendations: a cross-sectional survey among people with inflammatory joint disease in four European countries.

OBJECTIVES: Self-monitoring of physical activity (PA) has the potential to contribute to successful behaviour change in PA interventions in different populations, including people with inflammatory joint diseases (IJDs). The objectives of this study were to describe the use and knowledge of self-report-based and device-based PA measures in people with IJDs in four European countries, and to explore if the use of such devices, sociodemographic or disease-related variables were associated with adherence to the recommendations of at least 150 min of moderate to vigorous PA per week. SETTING: Cross-sectional survey, performed in 2015-2016. PARTICIPANTS: People with IJDs in Belgium, Denmark, Ireland and Sweden. PRIMARY AND SECONDARY OUTCOME MEASURES: Use of self-report and device-based PA measures, receipt of instructions how to use PA measures, confidence in using them, adherence to PA recommendations and associated factors for adherence to PA recommendations. RESULTS: Of the 1305 respondents answering questions on PA measures, 600 (46%) reported use of any kind of self-report or device-based measures to self-monitor PA. Between country differences of 34%-58% was observed. Six per cent and four per cent received instructions from health professionals on how to use simple and complex devices, respectively. Independent associated factors of fulfilment of recommendations of PA were living in Ireland (OR=84.89, p<0.001) and Sweden (OR=1.68, p=0.017) compared with living in Denmark, not perceiving activity limitations in moderate activities (OR=1.92, p<0.001) and using a device to measure PA (OR=1.56, p<0.001). Those living in Belgium (OR=0.21, p<0.001) were less likely to fulfil recommendations of PA. CONCLUSIONS: Almost half of the participants with IJDs used self-report-based or deviced-based PA measures, although few used wearable devices regularly. The results indicate that participants meeting public PA health guidelines were engaged in self-monitoring of PA.

Treatment of Provoked Vulvodynia: A Systematic Review.

BACKGROUND: Treatment recommendations for provoked vulvodynia (PVD) are based on clinical experiences and there is a need for systematically summarizing the controlled trials in this field. AIM: To provide an overview of randomized controlled trials and non-randomized studies of intervention for PVD, and to assess the certainty of the scientific evidence, in order to advance treatment guidelines. DATA SOURCES: The search was conducted in CINAHL (EBSCO), Cochrane Library, Embase (Embase.com), Ovid MEDLINE, PsycINFO (EBSCO) and Scopus. Databases were searched from January 1, 1990 to January 29, 2021. STUDY ELIGIBILITY CRITERIA: Population: Premenopausal women with PVD. INTERVENTIONS: Pharmacological, surgical, psychosocial and physiotherapy, either alone or as combined/team-based interventions. CONTROL: No treatment, waiting-list, placebo or other defined treatment. OUTCOMES: Pain during intercourse, pain upon pressure or touch of the vaginal opening, sexual function/satisfaction, quality of life, psychological distress, adverse events and complications. STUDY DESIGN: Randomized controlled trials and non-randomized studies of interventions with a control group. STUDY APPRAISAL AND SYNTHESIS METHODS: 2 reviewers independently screened citations for eligibility and assessed relevant studies for risk of bias using established tools. The results from each intervention were summarized. Studies were synthesized using a narrative approach, as meta-analyses were not considered appropriate. For each outcome, we assessed the certainty of evidence using grading of recommendations assessment, development, and evaluation (GRADE). RESULTS: Most results of the evaluated studies in this systematic review were found to have very low certainty of evidence, which means that we are unable to draw any conclusions about effects of the interventions. Multimodal physiotherapy compared with lidocaine treatment was the only intervention with some evidential support (low certainty of evidence for significant treatment effects favoring physiotherapy). It was not possible to perform meta-analyses due to a heterogeneity in interventions and comparisons. In addition, there was a heterogeneity in outcome measures, which underlines the need to establish joint core outcome sets. CLINICAL IMPLICATIONS: Our result underscores the need of stringent trials and defined core outcome sets for PVD. STRENGTH AND LIMITATIONS: Standard procedures for systematic reviews and the Population Intervention Comparison Outcome model for clinical questions were used. The strict eligibility criteria resulted in limited number of studies which might have resulted in a loss of important information. CONCLUSION: This systematic review underlines the need for more methodologically stringent trials on interventions for PVD, particularly for multimodal treatments approaches. For future research, there is a demand for joint core outcome sets. Bohm-Starke N, Ramsay KW, Lytsy P, et al. Treatment of Provoked Vulvodynia: A Systematic Review. J Sex Med 2022;19:789-808.

Identification and Prediction of Fatigue Trajectories in People With Rheumatoid Arthritis.

OBJECTIVE: We aimed to identify groups demonstrating different long-term trajectories of fatigue among people with rheumatoid arthritis and determine baseline predictors for these trajectories. METHODS: Our study included 2741 people aged 18 to 75 years who were independent in daily living. Data were collected from the Swedish Rheumatology Quality Register and questionnaires at baseline, 14 months, and 26 months. Fatigue was rated on a 100-mm visual analog scale. K-means cluster analysis was used to identify fatigue trajectories. Multinomial logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals for potential predictors of trajectory membership. RESULTS: The mean age was 60 years, 73% of participants were female, and the mean baseline fatigue level was 39. Three distinct fatigue trajectories were identified, representing mild (mean 15, n = 1024), moderate (mean 41, n = 986), and severe (mean 71, n = 731) fatigue. Consistent patterns indicated that poorer health perception (ORs 1.68-18.40), more pain (ORs 1.38-5.04), anxiety/depression (ORs 0.85-6.19), and activity limitation (ORs 1.43-7.39) were associated with more severe fatigue. Those in the severe fatigue group, compared with those in the mild fatigue group, were more likely to be college educated than university educated (OR 1.56) and less likely to maintain physical activity (OR 0.54). Those in the severe fatigue group, compared with those in both the moderate (OR 0.67) and mild (OR 0.59) fatigue groups, were less likely to have one additional adult in the household. CONCLUSION: This study identified stable fatigue trajectories, predicted by health perception, pain, anxiety/depression, activity limitation, educational level, maintained physical activity, and household composition. Interventions aimed at reducing these disabilities and supporting physical activity behaviors may help reduce fatigue.

Cardiovascular Autonomic Function Changes and Predictors During a 2-Year Physical Activity Program in Rheumatoid Arthritis: A PARA 2010 Substudy.

Background: Chronic inflammation leads to autonomic dysfunction, which may contribute to the increased risk of cardiovascular diseases (CVD) in patients with rheumatoid arthritis (RA). Exercise is known to restore autonomic nervous system (ANS) activity and particularly its parasympathetic component. A practical clinical tool to assess autonomic function, and in particular parasympathetic tone, is heart rate recovery (HRR). The aim of this substudy from the prospective PARA 2010 study was to determine changes in HRR post-maximal exercise electrocardiogram (ECG) after a 2-year physical activity program and to determine the main predictive factors associated with effects on HRR in RA. Methods: Twenty-five participants performed physiotherapist-guided aerobic and muscle-strengthening exercises for 1 year and were instructed to continue the unsupervised physical activity program autonomously in the next year. All participants were examined at baseline and at years 1 and 2 with a maximal exercise ECG on a cycle ergometer. HRR was measured at 1, 2, 3, 4, and 5 min following peak heart rate during exercise. Machine-learning algorithms with the elastic net linear regression models were performed to predict changes in HRR1 and HRR2 at 1 year and 2 years of the PARA program. Results: Mean age was 60 years, range of 41-73 years (88% women). Both HRR1 and HRR2 increased significantly from baseline to year 1 with guided physical activity and decreased significantly from year 1 to year 2 with unsupervised physical activity. Blood pressure response to exercise, low BMI, and muscular strength were the best predictors of HRR1/HRR2 increase during the first year and HRR1/HRR2 decrease during the second year of the PARA program. Conclusion: ANS activity in RA assessed by HRR was improved by guided physical activity, and machine learning allowed to identify predictors of the HRR response at the different time points. HRR could be a relevant marker of the effectiveness of physical activity recommended in patients with RA at high risk of CVD. Very inactive and/or high CVD risk RA patients may get substantial benefits from a physical activity program.

"A Necessary Investment in Future Health": Perceptions of Physical Activity Maintenance Among People With Rheumatoid Arthritis.

OBJECTIVE: A few studies with a qualitative design have addressed physical activity (PA) maintenance in people with rheumatoid arthritis (RA), but none of them focused specifically on maintenance of PA according to public health recommendations. The purpose of this study was to describe perceptions of PA maintenance during the second year of an outsourced 2-year support program among people with RA. METHODS: For this descriptive design with a qualitative inductive approach, semi-structured interviews were conducted with 18 participants with RA (3 men and 15 women). Variation in age, disease duration, activity limitation, pain, levels of PA, and PA maintenance was targeted through strategic sampling. Qualitative content analysis was used, and a pattern of theme, subthemes, and categories was constructed based on the participants' perceptions of PA maintenance. RESULTS: A main overarching theme, "A necessary investment in future health"-with 3 subthemes of dedication, awareness, and affinity-was identified as participants' perceptions of PA maintenance. Eight categories further described are a changed mindset, habits, commitments, monitoring, insights in PA, health gains, social support, and PA context. CONCLUSIONS: PA according to public health recommendations was perceived as a true investment in future health and wellness requiring dedication, awareness, and affinity. To promote PA maintenance, physical therapists working with people with chronic conditions should consider strengthening these prerequisites by targeting patients' negative attitudes to PA, supporting their creation of PA habits to incorporate in daily routines, introducing monitoring of PA intensity, supporting development of PA self-regulation skills, and providing suitable gym facilities with the possibility of peer support.

Long-term, health-enhancing physical activity is associated with reduction of pain but not pain sensitivity or improved exercise-induced hypoalgesia in persons with rheumatoid arthritis.

BACKGROUND: We aimed to evaluate the 1-year and 2-year outcome of a health-enhancing physical activity (HEPA) support program on global pain, pressure pain sensitivity, and exercise-induced segmental and plurisegmental hypoalgesia (EIH) in persons with rheumatoid arthritis (RA). METHODS: Thirty participants (27 women and 3 men) were recruited from a larger intervention cohort that engaged in strength training and moderate-intensity aerobic activity. Assessments were performed before the HEPA intervention and at 1-year and 2-year follow-ups. Global pain was assessed on a visual analogue scale (0-100). Pressure pain thresholds (PPTs) and suprathreshold pressure pain at rest corresponding to 4/10 (medium pain) (SP4) and 7/10 (strong pain) (SP7) on Borg CR 10 scale were assessed by algometry. In a subsample (n = 21), segmental and plurisegmental EIH were assessed during standardized submaximal static contraction (30% of the individual maximum), by algometry, alternately at the contracting right M. quadriceps and the resting left M. deltoideus. RESULTS: Global pain decreased from before the intervention to 2-year follow-up (median 11 to median 6, P = 0.040). PPTs and SP4 pressure pain at rest did not change from before the intervention to 2-year follow-up, while SP7 decreased from mean 647 kPa to mean 560 kPa (P = 0.006). Segmental EIH during static muscle contraction increased from the assessment before the intervention (from mean 1.02 to mean 1.42, P = 0.001), as did plurisegmental EIH (from mean 0.87 to mean 1.41, P <0.001). There were no statistically significant changes in segmental or plurisegmental EIH from before the intervention to 2-year follow-up. CONCLUSION: Participation in a long-term HEPA support program was associated with reduced global pain, whereas pressure pain sensitivity at rest was not reduced and EIH did not change. Thus, our results do not favor the hypothesis that long-term HEPA reduces pain by improving descending pain inhibition in persons with RA.

Associations between fatigue and physical capacity in people moderately affected by rheumatoid arthritis.

To explore the contribution of physical capacity in explaining variations in fatigue among people with rheumatoid arthritis (RA). This study included participants recruited for a physical activity intervention. Data were collected from the Swedish Rheumatology Quality Registers, from questionnaires on fatigue, activity limitation, perceived health, pain and anxiety/depression and from physical capacity tests (lower limb function, grip strength, and aerobic capacity). We used logistic regression to estimate the association between severe fatigue (≥ 50, visual analogue scale 0-100) and (A) independent variables related to disease and disease impact and (B) model A plus physical capacity tests. Pooled odds ratio tests compared model fit. Out of the 269 participants (mean age 60 years, mean disease activity score [DAS28] 2.8), severe fatigue was reported by 35%. The three variables which were statistically significantly associated with severe fatigue (p < 0.05) in both models were perceived health, pain and anxiety/depression. Anxiety/depression demonstrated the largest effect size with odds ratios of 2.43 (95% CI 1.20, 4.94) in model A and 2.58 (95% CI 1.25, 5.32) in model B. The likelihood ratio test indicated that model B was a better fit to the data than model A with Χ2 (df 3) = 2.65, p = 0.048. Severe fatigue in people with RA is associated with self-rated health, pain and anxiety/depression rather than with physical capacity. Future studies should be prospective, use multidimensional assessments of fatigue to explore the influence of physical capacity and control for possible influence of comorbidities associated with fatigue.

A survey across four European countries to determine rheumatology health professionals' awareness of physical activity measures in people with inflammatory joint diseases.

OBJECTIVES: The objectives of this study were to determine rheumatology health professionals' (HPs)' awareness of and confidence in using physical activity (PA) measures in people with inflammatory joint diseases (IJDs), their own self-reported PA levels and to identify HP-related educational needs. METHODS: Rheumatology HPs in Denmark, Sweden, Ireland and Belgium participated in an on-line survey. Descriptive statistics and latent class analysis (LCA) were undertaken SPSS (v21and SASv9.4) to describe data aggregates and range and to identify subclasses of groups with respect to use of PA measures. RESULTS: 322 (n=322, 75.5% women) HPs responded from Denmark (n=50, 15.5%), Sweden (n=66, 20.5%), Ireland (n=28, 8.7%) and Belgium (n=178, 55.3%) and the majority of respondents (n=286, 91.7%) reported it was important to measure PA in people with IJDs. Only 28.2% of HPs used simple body worn sensors to measure PA levels in their patients. The majority were interested in on-line education on measuring PA (82.9%). LCA, used to generate classes of PA measures employed by HPs, revealed three distinct classes reflecting differences in self-reported PA levels, awareness of PA measures, further education requirements and professional background. CONCLUSIONS: The majority of respondents reported that they considered measuring PA as important in people with IJDs; however, the majority lacked confidence in how to measure it. There was strong interest in further education around measuring PA. Three distinct respondent classes were identified to inform targeted education on how to measure PA.

An Outsourced Health-enhancing Physical Activity Program for People with Rheumatoid Arthritis: Study of the Maintenance Phase.

OBJECTIVE: To describe changes of health-enhancing physical activity (HEPA), health perception, and functioning during the second year of a 2-year support program, determine aspects of adherence and response, and describe perceptions of the program. METHODS: Out of 220 individuals with rheumatoid arthritis (RA), 177 participated in the followup. Group support, strength training, and moderate-intensity aerobic activity were encouraged. Data collection included HEPA, perceived health, functioning, and perceptions of the program. Participants with unchanged/improved general health perception and at least 2 of aerobic capacity, grip strength, or timed standing were considered responders. RESULTS: Current and maintained HEPA decreased from 82% to 75% (p = 0.0141) and from 41% to 27% (p < 0.0001) during the second year. Minor declines in quality of life and activity limitation occurred (p = 0.0395 and 0.0038, respectively), while outcome expectations for benefits of physical activity increased (p = 0.0010 and 0.0186) and waist circumference tapered off (p = 0.0070). Strength training was performed on average 41 and 35 times among responders (n = 54) and nonresponders (n = 105), respectively (p = 0.2708); HEPA 194 and 171 days, respectively (p = 0.0828); and support group meetings 12 and 10 times, respectively (p = 0.0943). Strength training, aerobic activity, and short text message reminders were perceived as most valuable; step registration and the self-monitoring walk tests were less appreciated. CONCLUSION: About one-fourth of the originally sedentary individuals with RA sustained their new HEPA behaviors after 2 years and most improvements of health and functioning were sustained. Structured use of behavior change techniques and a second year to support maintenance with a reduced program might help patients with RA to sustain HEPA behavior.

Pain sensitivity at rest and during muscle contraction in persons with rheumatoid arthritis: a substudy within the Physical Activity in Rheumatoid Arthritis 2010 study.

BACKGROUND: We aimed to explore pressure pain sensitivity and the function of segmental and plurisegmental exercise-induced hypoalgesia (EIH) in persons with rheumatoid arthritis (RA) compared with healthy control subjects (HC). METHODS: Forty-six participants with RA (43 female, 3 male) and 20 HC (16 female, 4 male) participated in the study. Pressure pain thresholds, suprathreshold pressure pain at rest, and segmental and plurisegmental EIH during standardised submaximal contractions were assessed by algometry. Assessments of EIH were made by performing algometry alternately at the contracting (30% of the individual maximum) right m. quadriceps and the resting left m. deltoideus. RESULTS: Participants with RA had higher sensitivity to pressure pain (RA, 318 kPa; HC, 487 kPa; p < 0.001), suprathreshold pressure pain 4/10 (RA, 433 kPa; HC, 638 kPa; p = 0.001) and suprathreshold pressure pain 7/10 (RA, 620 kPa; HC, 851 kPa; p = 0.002) than HC. Segmental EIH (RA, 0.99 vs 1.27; p < 0.001; HC, 0.89 vs 1.10; p = 0.016) and plurisegmental EIH (RA, 0.95 vs 1.36; p < 0.001; HC, 0.87 vs 1.31; p < 0.001) increased significantly during static muscle contraction in both groups alike (p > 0.05). CONCLUSIONS: Our results indicate a generally increased pain sensitivity but normal function of EIH among persons with RA and offer one possible explanation for pain reduction observed in this group of patients following clinical exercise programmes.

Trajectories of Fear-Avoidance Beliefs on Physical Activity Over Two Years in People With Rheumatoid Arthritis.

OBJECTIVE: To identify and describe 2-year trajectories of fear-avoidance beliefs on physical activity and to identify predictors of these trajectories in people with rheumatoid arthritis (RA). METHODS: We included 2,569 persons with RA (77% women, mean age 58 years). Data on fear-avoidance beliefs (Fear-Avoidance Beliefs Questionnaire physical activity subscale [FABQ-PA]; range 0-24), sociodemographics, disease-related variables, self-efficacy, and health-enhancing physical activity (HEPA) were collected from registers and by questionnaires at baseline, 14, and 26 months. K-means cluster analysis was used to identify fear-avoidance trajectories, and multinomial logistic regression was used to identify predictors of trajectory membership. RESULTS: Three trajectories of fear-avoidance beliefs were identified: low (n = 1,060, mean FABQ-PA = 3), moderate (n = 1,043, mean FABQ-PA = 9), and high (n = 466, mean FABQ-PA = 15). Consistent predictors of being in the high fear-avoidance trajectory versus the other 2 trajectories were high activity limitation, male sex, income below average, not performing current HEPA, and elevated anxiety/depression. In addition, less consistent predictors such as shorter education, more pain, and low exercise self-efficacy were also identified. CONCLUSION: Stable trajectories of fear-avoidance beliefs on physical activity exist among people with RA. Fear-avoidance may be targeted more effectively by tailoring physical activity promotion to vulnerable socioeconomic groups, men, and those with high activity limitation and anxiety/depression.

Pain rather than self-reported sedentary time explains variation in perceived health and activity limitation in persons with rheumatoid arthritis: a cross sectional study in Sweden.

To investigate (1) the amount of self-reported time spent sedentary among a large cohort of persons with rheumatoid arthritis (RA), and (2) the contribution of sedentary time to explain perceived health and activity limitation in RA beyond that of previously known correlates. This cross-sectional study used data from a postal questionnaire and the Swedish Rheumatology Quality registers (SRQ). The International Physical Activity Questionnaire was used to assess sedentary time (sitting) and moderate, vigorous and walking activity (MVPA). Sociodemographics, pain, fatigue, fear-avoidance beliefs, anxiety/depression, disease duration, MVPA and sedentary time were included in multiple regression models with perceived health (Visual Analogue Scale 0-100) and activity limitation (Stanford Health Assessment Questionnaire) as dependent variables. RESULTS: In all 3152 (59%) of 5391 persons identified as eligible from the SRQ, responded to the questionnaire. 2819 individuals with complete data on all study variables were analysed. Mean time (SD) spent sedentary was 257 (213) minutes per day. Sedentary time did not contribute significantly to explain perceived health and only minimally to explain activity limitation. Instead, variation was mainly explained by pain; for perceived health (Beta = 0.780, p < 0.001) and for activity limitation (Beta = 0.445, p < 0.001).The results indicate a non-significant role of sedentary time and a need for increased focus on pain in the management of RA. Future studies should use prospective designs and objective assessment methods to further investigate the associations between sedentary time and health outcomes in persons with RA.

Trajectories of Physical Activity Over Two Years in Persons With Rheumatoid Arthritis.

OBJECTIVE: To identify and describe different trajectories of physical activity over 2 years and to identify baseline predictors for each trajectory within a large cohort of people with rheumatoid arthritis (RA). METHODS: The sample included 2,752 people ages 18-75 years and independent in daily living. Data on sociodemographic, disease-related, and psychosocial variables and physical activity (total weekly hours of vigorously/moderately intense activity and walking) were collected from registers and by questionnaires at baseline, and at 14 and 26 months. K-means cluster analysis was used to identify different physical activity trajectories. Multinomial logistic regression was used to identify predictors of trajectory membership. RESULTS: Three trajectories were identified: 1 stable high (n = 272; with an average of 25 hours of physical activity/week), 1 decreasing (n = 564; changing from 22 to 8 hours), and 1 stable low (n = 1,916; with an average of 3 hours). Predictors of the stable high trajectory versus the other 2 were male sex and already established physical activity at baseline. Predictors of the stable high trajectory versus decreasing trajectory were lower age and less social support for exercise, while predictors of stable high versus the stable low trajectory were less activity limitation and higher exercise self-efficacy. CONCLUSION: The results indicate that distinct trajectories of physical activity over 2 years in people with RA exist, and that stable, high physical activity is mainly predicted by male sex and already established physical activity at baseline. Additional predictors, amenable to change, include activity limitation, social support, and self-efficacy for exercise, suggesting a wide perspective on maintained physical activity in RA.

Criterion Validity of the activPAL Activity Monitor for Sedentary and Physical Activity Patterns in People Who Have Rheumatoid Arthritis.

BACKGROUND: Accurate measurement of physical activity and sedentary behavior is an important consideration for health care professionals. The activPAL activity monitor has not been validated against a criterion measure for people with rheumatoid arthritis (RA). OBJECTIVE: The objective of this study was to determine the criterion validity of the activPAL activity monitor for measuring step counts, transition counts, and time spent in sedentary, standing, and walking behaviors in people with RA. DESIGN: A laboratory-based criterion validation study was conducted. METHODS: Participants with a confirmed medical diagnosis of RA were recruited from 2 outpatient rheumatology clinics. The testing procedure consisted of standardized testing components and tasks related to activities of daily living. Participants wore an activPAL activity monitor and were video recorded throughout the testing procedure. Direct observation was used as the criterion measure. Data analysis consisted of validation analysis of the activPAL activity monitor data and the criterion measure data. RESULTS: Twenty-four people participated in the study. Data from 20 participants were included in the final analysis. The activPAL significantly underestimated step counts by 26% and transition counts by 36%. There was no significant difference between the activPAL activity monitor and the criterion measure for time spent in sedentary, standing or light activity, and walking behaviors. LIMITATIONS: Validation of activities of daily living in a laboratory environment is a limitation of this study. CONCLUSIONS: The activPAL activity monitor underestimated step and transition counts and, therefore, is not valid for measuring these outcomes in people with RA. Relative to direct observation, the activPAL activity monitor is valid for measuring time spent in sedentary, standing, and walking behaviors in people with RA.

The Swedish Exercise Self-Efficacy Scale (ESES-S): reliability and validity in a rheumatoid arthritis population.

PURPOSE: The aim of the present study was to investigate aspects of reliability and validity of the Exercise Self-Efficacy Scale (ESES-S) in a rheumatoid arthritis (RA) population. METHODS: A total of 244 people with RA participating in a physical activity study were included. The six-item ESES-S, exploring confidence in performing exercise, was assessed for test-retest reliability over 4-6 months, and for internal consistency. Construct validity investigated correlation with similar and other constructs. RESULTS: An intraclass correlation coefficient (ICC) of 0.59 (95% CI 0.37-0.73) was found for 84 participants with stable health perceptions between measurement occasions. Cronbach's alpha coefficients of 0.87 and 0.89 were found at the first and second measurements. Corrected item-total correlation single ESES-S items ranged between 0.53 and 0.73. Construct convergent validity for the ESES-S was partly confirmed by correlations with health-enhancing physical activity and outcome expectations respectively (Pearson's r = 0.18, p < 0.01). Construct divergent validity was confirmed by the absence of correlations with age or gender. No floor or ceiling effects were found for ESES-S. CONCLUSIONS: The results indicate that the ESES-S has moderate test-retest reliability and respectable internal consistency in people with RA. Construct validity was partially supported in the present sample. Further research on construct validity of the ESES-S is recommended. IMPLICATIONS FOR REHABILITATION: Physical exercise is crucial for management of symptoms and co-morbidity in rheumatoid arthritis. Self-efficacy for exercise is important to address in rehabilitation as it regulates exercise motivation and behavior. Measurement properties of self-efficacy scales need to be assessed in specific populations and different languages.

"A gift from heaven" or "This was not for me". A mixed methods approach to describe experiences of participation in an outsourced physical activity program for persons with rheumatoid arthritis.

Most persons with rheumatoid arthritis (RA) do not perform health-enhancing physical activity (HEPA). Evaluations of innovative HEPA programs need to be complemented with descriptive and qualitative data from the users. The aim of this mixed methods study was to explore and describe how a subgroup of the RA population perceives participation during the first year of an outsourced 2-year HEPA program. Data were collected by a study-specific postal survey to 220 program participants (response rate 87%, n = 191) and by interviews with a purposefully selected subsample of 35, including completers and dropouts. The survey data were analyzed by descriptive statistics and the interviews by qualitative content analysis.The survey demonstrated increased self-reported physical activity in 165 participants (86%). After the first year of the program, participants reported having performed "regular" or "periodical" circuit training (78%) and physical activity in daily life (92%). The most valued program components were circuit training and physical activity in daily life, both rated median 5/5. Coach support, prompts by text messages, and expert lectures were rated median 4/5. Five categories emerged from the interviews describing expectations, facilitators, gains, maintenance, and obstacles/suggestions for improvement of the program. The results demonstrate that HEPA outside health care is highly appreciated by a subgroup of the RA population. Professional coaching and prompts by text messages seem to be particularly useful facilitators. Individual preferences emphasize the need to tailor settings, exercise formats, and behavioral support for HEPA even in a narrow, self-selected group with RA.

An outsourced health-enhancing physical activity programme for people with rheumatoid arthritis: exploration of adherence and response.

OBJECTIVES: The aims of this study were to document adherence to and changes in health-enhancing physical activity (HEPA) levels and self-reported and assessed functioning and to explore aspects of adherence and response during the first year of an outsourced 2-year HEPA programme in people with RA. METHODS: Two-hundred and twenty patients participated in this observational cohort study, which included daily physical activity, twice-weekly circuit training and biweekly support group meetings. Self-reported data included current (past week) and maintained (past 6 months) HEPA levels, sociodemographics and disease-related and psychosocial factors. Tests of aerobic capacity and muscle function were performed and anthropometric data were collected. RESULTS: Eighty-eight per cent of the participants completed 1 year assessments. Self-reported current and maintained HEPA increased. General health perception and a number of other self-reported disease-related and psychosocial factors improved, while exercise self-efficacy declined. Aerobic capacity, timed standing and grip strength improved and waist circumference decreased. The mean number of circuit training sessions performed was 48, the mean number of days with HEPA was 189 and the mean number of support group meetings attended was 9. Better adherence to circuit training improved general health, and better adherence to group meetings improved timed standing. Exercise self-efficacy improved among those adhering more to circuit training or support group meetings. CONCLUSION: The outsourced HEPA programme had high retention and reasonable adherence. A number of health outcomes improved. Relationships between adherence to the programme components and response were not clear-cut and need further attention.

Criterion validation of two submaximal aerobic fitness tests, the self-monitoring Fox-walk test and the Åstrand cycle test in people with rheumatoid arthritis.

BACKGROUND: Aerobic capacity tests are important to evaluate exercise programs and to encourage individuals to have a physically active lifestyle. Submaximal tests, if proven valid and reliable could be used for estimation of maximal oxygen uptake (VO2max). The purpose of the study was to examine the criterion-validity of the submaximal self-monitoring Fox-walk test and the submaximal Åstrand cycle test against a maximal cycle test in people with rheumatoid arthritis (RA). A secondary aim was to study the influence of different formulas for age predicted maximal heart rate when estimating VO2max by the Åstrand test. METHODS: Twenty seven subjects (81% female), mean (SD) age 62 (8.1) years, diagnosed with RA since 17.9 (11.7) years, participated in the study. They performed the Fox-walk test (775 meters), the Åstrand test and the maximal cycle test (measured VO2max test). Pearson's correlation coefficients were calculated to determine the direction and strength of the association between the tests, and paired t-tests were used to test potential differences between the tests. Bland and Altman methods were used to assess whether there was any systematic disagreement between the submaximal tests and the maximal test. RESULTS: The correlation between the estimated and measured VO2max values were strong and ranged between r = 0.52 and r = 0.82 including the use of different formulas for age predicted maximal heart rate, when estimating VO2max by the Åstrand test. VO2max was overestimated by 30% by the Fox-walk test and underestimated by 10% by the Åstrand test corrected for age. When the different formulas for age predicted maximal heart rate were used, the results showed that two formulas better predicted maximal heart rate and consequently a more precise estimation of VO2max. CONCLUSIONS: Despite the fact that the Fox-walk test overestimated VO2max substantially, the test is a promising method for self-monitoring VO2max and further development of the test is encouraged. The Åstrand test should be considered as highly valid and feasible and the two newly developed formulas for predicting maximal heart rate according to age are preferable to use when estimating VO2max by the Åstrand test.

Who makes it to the base? Selection procedure for a physical activity trial targeting people with rheumatoid arthritis.

OBJECTIVE: To compare those who were finally included in a large well-defined sample of individuals with rheumatoid arthritis (RA) at target for a physical activity (PA) trial with those who were not. METHODS: In total, 3,152 individuals answered questionnaires on sociodemographic, disease-related, and psychosocial factors and PA levels. The differences between individuals making it to the baseline assessments and those who did not were analyzed in 3 steps. RESULTS: In a first step, 1,932 individuals were eligible for the trial if they were interested in participating, not physically active enough, and fluent in Swedish and if they were not participating in any other study. The participants were mainly younger women, had higher education and income, were more likely to live with children, and had better support for exercise and had higher outcome expectations of PA than the 1,208 ineligible individuals. In a second step, the 286 individuals accepting participation had higher income and education, more support for exercise, less fear-avoidance beliefs, and higher outcome expectations of PA than the 1,646 individuals declining participation. In a third step, the 244 individuals assessed at baseline reported less fatigue than the 42 withdrawing before assessment. CONCLUSION: To our knowledge, this is the first study describing the entire selection procedure, from a target sample for a PA trial to the sample assessed at baseline, in individuals with RA. Factors other than those related to the disease seemed to mainly determine participation and largely resembled determinants in the general population. Sociodemographic and psychosocial factors should be recognized as important for PA in people with RA.
