Exercise habits and factors associated with exercise in systemic sclerosis: a Scleroderma Patient-centered Intervention Network (SPIN) cohort study

Effects of a telerehabilitation-based exercise program in patients with systemic sclerosis

BACKGROUND

This study aimed to evaluate the effect of telerehabilitation-based exercise programs in systemic sclerosis (SSc) patients.

METHODS

Forty-six SSc patients were randomly separated into two groups as telerehabilitation and control. Videos comprising clinical Pilates-based exercises were designed and uploaded to YouTube™ for the telerehabilitation group by physiotherapists. A video interview was conducted with the SSc patients once a week and an exercise program was performed twice daily for 8 weeks in the telerehabilitation group. The same exercise programs were printed on paper brochures and patients were instructed on their application in the form of a home exercise program to be continued for 8 weeks in the control group. Pain, fatigue, quality of life, sleep, physical activity, anxiety, and depression were assessed in all patients at the beginning and end of the study.

RESULTS

The clinical and demographic characteristics were similar in both groups (p > 0.05). Fatigue, pain, anxiety, and depression decreased in both groups, while quality of life and sleep quality increased after the exercise program (p < 0.05). However, the improvements in the telerehabilitation group were statistically more significant than in the control group for all studied parameters (p < 0.05).

CONCLUSION

The results of our study demonstrate the superior efficacy of telerehabilitation-based treatment programs over home exercise programs, hence, we suggest widespread use of this innovative treatment program in SSc patients.

Systematic literature review informing the EULAR recommendations for the non-pharmacological management of systemic lupus erythematosus and systemic sclerosis

Through this systematic literature review, we assembled evidence to inform the EULAR recommendations for the non-pharmacological management of systemic lupus erythematosus (SLE) and systemic sclerosis (SSc). We screened articles published between January 2000 and June 2021. Studies selected for data extraction (118 for SLE and 92 for SSc) were thematically categorised by the character of their intervention. Of 208 articles included, 51 were classified as robust in critical appraisal. Physical activity was the most studied management strategy and was found to be efficacious in both diseases. Patient education and self-management also constituted widely studied topics. Many studies on SLE found psychological interventions to improve quality of life. Studies on SSc found phototherapy and laser treatment to improve cutaneous disease manifestations. In summary, non-pharmacological management of SLE and SSc encompasses a wide range of interventions, which can be combined and provided either with or without adjunct pharmacological treatment but should not aim to substitute the latter when this is deemed required. While some management strategies i.e., physical exercise and patient education, are already established in current clinical practice in several centres, others e.g., phototherapy and laser treatment, show both feasibility and efficacy, yet require testing in more rigorous trials than those hitherto conducted.

Minimal Clinically Important Differences (MCID) for the Functional Assessment of Chronic Illness Therapy Fatigue Scale in Patients with Systemic Sclerosis

(1) Background: Systemic sclerosis (SSc) is characterized by significant fatigue, causing diminished quality of life (QoL). The aim of this study was to examine fatigue levels and their associations with clinical factors and determine the minimal clinically important difference (MCID) value for the Functional Assessment of Chronic Illness Therapy Fatigue Scale (FACIT-FS). (2) Methods: A total of 160 SSc patients and 62 individuals without SSc were followed-up over a 12-month period by measuring the FACIT-FS and the Visual Analogue Scale and the Short Form 36 Vitality Score analyzing changes in exhaustion. (3) Results: Fatigue was strongly correlated with HRQoL, level of pain, emotional disorders, physical capability and functionality. The MCID values for FACIT-FS were calculated as -3 for deterioration and +4 for improvement after a 12-month follow-up. The predictors of improvement of fatigue from baseline parameters were the significant disease activity, the patients' poorer functionality and the short disease duration. Patients with scleroderma-related interstitial lung disease at baseline had approximately tripled risks for worsening fatigue. The independent influential factors regarding the changing of FACIT-FS were improving or worsening in the same direction in reference to physical condition, gastrointestinal and emotional factors. (4) Conclusions: Fatigue is a multi-dimensional symptom, which is strongly correlated to HRQoL. MCID values of FACIT-FS can be useful tools in monitoring the changes of HRQoL in clinical trials and in daily practice among patients with SSc.

Exploring the effects of a combined exercise programme on pain and fatigue outcomes in people with systemic sclerosis: study protocol for a large European multi-centre randomised controlled trial

Background

Pain, related to Raynaud’s phenomenon or digital ulceration, has been identified as very prevalent and debilitating symptoms of systemic sclerosis (SSc), both significantly affecting patients’ quality of life (QoL). Pharmacological therapeutic strategies were found not to be sufficiently effective in the management of SSc-induced pain and fatigue, and evidence for exercise is scarce. As yet, the effects of a long-term, tailored exercise programme on pain and fatigue in patients with SSc have not been explored. In addition to pain and fatigue, this study aims to evaluate the effects of exercise on QoL, physical fitness, functional capacity, and vascular structure in people with SSc (PwSSc).

Methods

This will be a multicentre (n = 6) randomised controlled clinical trial to assess the effect of a previously established, supervised 12-week combined exercise programme on pain and fatigue as compared to no exercise in PwSSc. The study will recruit 180 patients with SSc that will be allocated randomly to two groups. Group A will perform the exercise programme parallel to standard usual care and group B will receive usual care alone. Patients in the exercise group will undertake two, 45-min sessions each week consisting of 30-min high-intensity interval training (HIIT) (30-s 100% peak power output/30-s passive recovery) on an arm crank ergometer and 15 min of upper body circuit resistance training. Patients will be assessed before as well as at 3 and 6 months following randomisation. Primary outcomes of the study will be pain and fatigue assessed via questionnaires. Secondary outcomes include quality of life, structure of digital microvasculature, body composition, physical fitness, and functional capacity.

Discussion

Data from this multi-centre research clinical trial will primarily be used to establish the effectiveness of a combined exercise protocol to improve pain and fatigue in SSc. In parallel, this study will be the first to explore the effects of long-term exercise on potential microvascular alterations assessed via NVC. Overall, this study will provide sufficient data to inform current clinical practice guidelines and may lead to an improvement of QoL for patients with SSc.

The Preventive Role of Physical Activity in Systemic Sclerosis: A Cross-Sectional Study on the Correlation with Clinical Parameters and Disease Progression

Although exercise is associated with improved health in many medical conditions, little is known about the possible influences of physical activity (PA) habits pre- and post- a diagnosis of systemic sclerosis (SSc) on disease activity and progression. This cross-sectional study assessed, for the first time, self-reported pre- and post-diagnostic PA levels with the aim to verify if changes in these levels were correlated with demographic/anthropometric data (e.g., weight, height, gender, age, BMI), disease duration, diagnostic/clinical parameters (e.g., skin involvement, pulmonary hemodynamic/echocardiographic data, disease activity) related to disease activity and progression, and quality of life in a population-based sample of patients with SSc. Adult participants (n = 34, age 56.6 ± 13.3 years) with SSc (limited cutaneous SSc, lcSSc, n = 20; diffuse cutaneous SSc, dcSSc, n = 9; sine scleroderma SSc, n = 5) were enrolled at the Division of Rheumatology and Clinical Immunology of the Humanitas Research Hospital. All medical data were recorded during periodic clinical visits by a rheumatologist. Moreover, all subjects included in this study completed extensive questionnaires to evaluate their health-related quality of life (HRQOL), and others related to health-related physical activity performed before (PRE) and after (POST) the diagnosis of disease. The linear regression analysis has shown that either a high Sport_index or Leisure_index in the PRE-diagnostic period was correlated with lower disease duration in dcSSc patients. Physical load during sport activity and leisure time accounted for ~61.1% and ~52.6% of the individual variation in disease duration, respectively. In lcSSc patients, a high PRE value related to physical load during sporting activities was correlated with a low pulmonary artery systolic pressure (sPAP) and the POST value of the Work_index was positively correlated with the left ventricular ejection fraction (LVEF), and negatively with creatine kinase levels (CK). Interestingly, the univariate analysis showed that Work_index accounts for ~29.4% of the variance in LVEF. Our analysis clearly reinforces the concept that high levels of physical load may play a role in primary prevention-delaying the onset of the disease in those subjects with a family history of SSc-as well as in secondary prevention, improving SSc management through a positive impact on different clinical parameters of the disease. However, it remains a priority to identify a customized physical load in order to minimize the possible negative effects of PA.

Fatigue and activity management education for individuals with systemic sclerosis: Adaptation and feasibility study of an intervention for a rare disease

Purpose

Fatigue is an overlooked symptom for musculoskeletal diseases, including rare conditions like systemic sclerosis (SSc). The purpose of this study were the following: (1) to adapt the content and delivery method of an existing fatigue intervention, and (2) to determine the feasibility of Fatigue and Activity Management Education in Systemic Sclerosis (FAME‐iSS).

Methods

In Phase 1 adaptations were recorded using the Framework for Modification and Adaptations. In Phase 2, participants completed the 6‐week FAME‐iSS intervention and baseline, post‐intervention, and 3‐month follow‐up assessments measuring fatigue levels, fatigue impact, mental health, self‐efficacy, and use of energy conservation strategies. Qualitative data included a post‐intervention focus group and 3‐month follow‐up interviews.

Results

Three main changes were made to the original intervention: (1) the content was adapted from management of Lupus‐related fatigue to management of SSc‐related fatigue, (2) context for delivery from Ireland to United States, and (3) in‐person to online format. Participants (n = 4) were 51.8 ± 12.1 years old, had been diagnosed with SSc for 12.0 ± 8.0 years, were receiving disability support, and had college degrees. All participants had 100% attendance and completed all study activities. Participants had positive comments about the programme format, content, and implementation. Post‐intervention, improvements were observed in most measures. Moderate effect sizes were noted in fatigue and self‐efficacy scores.

Conclusion

Participants' positive responses supported the need for FAME‐iSS for people with SSc. Even with the small sample, FAME‐iSS led to improvements in fatigue and use of energy conservation strategies. The online format allowed for participation and sharing of ideas, especially during the global pandemic.

Happiness, quality of life and their determinants among people with systemic sclerosis: a structural equation modelling approach

BACKGROUND

Patients' objectives and experiences must be core to the study and management of chronic diseases, such as SSc. Although patient-reported outcomes are attracting increasing attention, evaluation of the impact of disease on the overall subjective well-being, equivalent to 'happiness', is remarkably lacking.

OBJECTIVES

To examine the determinants of happiness and quality of life in patients with SSc, with emphasis on disease features and personality traits.

METHODS

Observational, cross-sectional multicentre study, including 142 patients, with complete data regarding disease activity, disease impact, personality, health-related quality of life (HR-QoL) and happiness. Structural equation modelling was used to evaluate the association between the variables.

RESULTS

The results indicated an acceptable fit of the model to the data. Perceived disease impact had a significant negative direct relation with HR-QoL (β = -0.79, P < 0.001) and with happiness (β = -0.52, P < 0.001). Positive personality traits had a positive relation with happiness (β = 0.36, P = 0.002) and an important indirect association upon QoL (β = 0.43) and happiness (β = 0.23). Perceived disease impact is influenced by body image, fatigue and SSc-related disability to a higher degree (β = 0.6-0.7) than by disease activity (β = 0.28) or form (β = 0.17). Impact of disease had a much stronger relation with HR-QoL than with happiness.

CONCLUSIONS

The results suggest that treatment strategies targeting not only disease control but also the mitigation of relevant domains of disease impact (body image, fatigue, global disability) may be important to improve patients' experience of the disease. The reinforcement of resilience factors, such as positive psychological traits, may also play a contributory role towards better patient outcomes.

Exercise as a multi-modal disease-modifying medicine in systemic sclerosis: An introduction by The Global Fellowship on Rehabilitation and Exercise in Systemic Sclerosis (G-FoRSS)

Systemic sclerosis (SSc) is a heterogeneous multisystem autoimmune disease whereby its main pathological drivers of disability and damage are vascular injury, inflammatory cell infiltration, and fibrosis. These mechanisms result in diffuse and diverse impairments arising from ischemic circulatory dysfunction leading to painful skin ulceration and calcinosis, neurovascular aberrations hindering gastrointestinal (GI) motility, progressive painful, incapacitating or immobilizing effects of inflammatory and fibrotic effects on the lungs, skin, articular and periarticular structures, and muscle. SSc-related impairments impede routine activities of daily living (ADLs) and disrupt three critical life areas: work, family, social/leisure, and also impact on psychological well-being. Physical activity and exercise are globally recommended; however, for connective tissue diseases, this guidance carries greater impact on inflammatory disease manifestations, recovery, and cardiovascular health. Exercise, through myogenic and vascular phenomena, naturally targets key pathogenic drivers by downregulating multiple inflammatory and fibrotic pathways in serum and tissue, while increasing circulation and vascular repair. G-FoRSS, The Global Fellowship on Rehabilitation and Exercise in Systemic Sclerosis recognizes the scientific basis of and advocates for education and research of exercise as a systemic and targeted SSc disease-modifying treatment. An overview of biophysiological mechanisms of physical activity and exercise are herein imparted for patients, clinicians, and researchers, and applied to SSc disease mechanisms, manifestations, and impairment. A preliminary guidance on exercise in SSc, a research agenda, and the current state of research and outcome measures are set forth.

Barriers and facilitators to physical activity for people with scleroderma: a Scleroderma Patient-centered Intervention Network (SPIN) Cohort study

OBJECTIVE

To support physical activity among people with systemic sclerosis (SSc; scleroderma), we sought to determine the (1) prevalence and importance of barriers and (2) likelihood of using possible facilitators.

METHODS

We invited 1,707 participants from an international SSc cohort to rate the (1) importance of 20 barriers (14 medical; 4 social or personal; 1 lifestyle; 1 environmental); and (2) likelihood of using 91 corresponding barrier-specific and 12 general facilitators.

RESULTS

Among 721 respondents, 13 barriers were experienced by ≥25% of participants, including 2 (fatigue, Raynaud's) rated 'important' or 'very important' by ≥50% of participants, 7 (joint stiffness and contractures, shortness of breath, gastrointestinal problems, difficulty grasping, pain, muscle weakness and mobility limitations, low motivation) by 26-50%, and 4 by <26%. Overall, 23 (18 medical-related) of 103 facilitators were rated by ≥75% as 'likely' or 'very likely' to use among those who experienced corresponding barriers; these facilitators focused on adapting exercise (e.g., using controlled, slow movement), taking care of one's body (e.g., stretching), keeping warm (e.g., wearing gloves), and protecting skin (e.g., covering ulcers). Among those who had previously tried the facilitator, all facilitators were rated by ≥50% as 'likely' or 'very likely' to use; among those with the barrier who had not tried the facilitator, only 12 of 103 were rated by >50% as 'likely' or 'very likely'.

CONCLUSION

Medical-related physical activity barriers were common and considered important. Facilitators considered as most likely to be used involved adapting exercise, taking care of one's body, keeping warm, and protecting skin.

Physical or Occupational Therapy Use in Systemic Sclerosis: A Scleroderma Patient-centered Intervention Network Cohort Study

OBJECTIVE

Systemic sclerosis (SSc) is characterized by significant disability because of musculoskeletal involvement. Physical and occupational therapy (PT/OT) have been suggested to improve function. However, the rate of PT/OT use has been shown to be low in SSc. We aimed to identify demographic, medical, and psychological variables associated with PT/OT use in SSc.

METHODS

Participants were patients with SSc enrolled in the Scleroderma Patient-centered Intervention Network (SPIN) Cohort. We determined the rate and indication of PT/OT use in the 3 months prior to enrollment. Multivariable logistic regression was used to identify variables independently associated with PT/OT use.

RESULTS

Of the 1627 patients with SSc included in the analysis, 23% used PT/OT in the preceding 3 months. PT/OT use was independently associated with higher education (OR 1.08, 95% CI 1.04-1.12), having moderately severe small joint contractures (OR 2.09, 95% CI 1.45-3.03), severe large joint contractures (OR 2.33, 95% CI 1.14-4.74), fewer digital ulcerations (OR 0.70, 95% CI 0.51-0.95), and higher disability (OR 1.54, 95% CI 1.18-2.02) and pain scores (OR 1.04, 95% CI 1.02-1.06). The highest rate of PT/OT use was reported in France (43%) and the lowest, in the United States (17%).

CONCLUSION

Despite the potential of PT/OT interventions to improve function, < 1 in 4 patients with SSc enrolled in a large international cohort used PT/OT services in the last 3 months. Patients who used PT/OT had more severe musculoskeletal manifestations and higher pain and disability.

Physical activity in patients with systemic sclerosis

OBJECTIVES

To compare self-reported levels of physical activity (PA) of systemic sclerosis (SSc) patients with the general population. To evaluate in SSc patients factors associated with PA levels and needs and preferences regarding PA.

METHODS

Fifty nine SSc patients completed the Short QUestionnaire to ASsess Health-Enhancing PA. The proportion of patients meeting the Dutch Recommendation for PA (= moderate PA for 30 min on ≥ 5 days/week) and total minutes of PA per week were calculated and compared with similar data from the Dutch population. Characteristics were univariately and multivariately compared between patients with low and high PA levels (either ≤ or > mean minutes/week of the Dutch population). Needs and preferences regarding PA promotion and guidance related to exercise were assessed by questionnaires.

RESULTS

Stratified for age (< 55 or ≥ 55 years) and gender, the proportion SSc patients meeting the Dutch recommendation for PA was not significantly different from the Dutch population. The total minutes of PA per week was significantly lower among SSc patients (1704 vs. 2614, P < 0.001). Multivariable analyses showed that in SSc patients the male gender, scleroderma health assessment questionnaire (SHAQ) and lack of energy were significantly associated with lower PA levels (P = 0.007; P = 0.042; P = 0.025). Two-third of patients required more information about PA.

CONCLUSION

In SSc patients, the total minutes of PA per week are significantly lower compared to the general population. The male gender, functional ability as reflected by SHAQ and lack of energy seem to interfere with PA. These results might guide health professionals in providing their patients with appropriate information on PA.
