Study Design

A qualitative research study comprising online participant focus groups in adults with SSc was developed and conducted to capture barriers and facilitators to exercise experience by people with SSc. This study was approved by the University of Southern Queensland Human Research Ethics Committee (ethics approval number: H21REA094, approved June 2021).

Participants

The study inclusion criteria included participants aged ≥18 years old; English speaking; access to a laptop, tablet, or mobile phone device; ability to provide informed consent; and diagnosed with SSc according to the European League Against Rheumatism (EULAR) or America College of Rheumatology (ACR) classification criteria (3,4). Enrollment decisions were guided by a purposive sampling framework (21), developed by the research team, to ensure a representative participant cohort with respect to disease subtype (mixture of limited and diffuse), disease duration (<10 and ≥10 years), demographic location within Australia (mixture between states), and exercise participation (mixture between exercisers and nonexercisers). Participants were recruited via snowball sampling through advertisement in the Scleroderma New South Wales (NSW) and Scleroderma Australia social media groups, websites, and newsletters. Each focus group was limited to a maximum of 8 participants to ensure all participants had the opportunity to express their personal views and could confidently challenge alternate or opposing experiences expressed within the group. A minimum of one focus group was originally planned, with an intention to undertake additional focus groups until thematic saturation was achieved (22).

Data Collection

Participant demographic information was collected by the principal investigator (SF) prior to the focus groups to guide purposive sampling. Information included demographics such as age, sex, work status, home location, disease type, duration, and manifestations, and exercise participation. Each of the 3 focus groups lasted approximately 1 hour in duration, were conducted on Zoom (online video communication software, San Jose, California) between August 2021 and September 2021, led by author SF, and were audio-recorded, transcribed, and anonymized. An interview guide was developed by the research team (authors SF, MC) and reviewed by a registered psychologist.

Data Analysis

Qualitative analysis of the focus group transcripts was undertaken by all members of the research team (SF, CC, SB, MC) to ensure a fair and unbiased appraisal of the experiences expressed. Reflexive thematic analysis was adopted in accordance with qualitative research guidelines, ensuring findings were grounded in shared person experiences rather than imposed from existing concepts (23–26). Data analysis software (NVivo, QSR International, release 1.5.1, Burlington, Massachusetts) was used to facilitate qualitative analysis. During the transcription phase, participants were deidentified using alphanumeric codes characterized by disease duration (For example, F01). Initially, anonymized transcripts were read multiple times independently by authors SF and CC, and initial words or phrases (codes) that captured important experiences derived from the research questions were independently applied to each transcript to ensure a rigorous analysis and to minimize researcher bias. The codes were then explored and refined during several discussions between authors SF and CC to see how conceptually related codes could be grouped to form themes and sub-themes (23). This process was an iterative one, undertaken concurrently with data collection, allowing emerging themes to be explored in subsequent groups. After a preliminary independent analysis of the data and several discussions, revisions of the themes were conducted by the research team (authors SF, CC, MC, SB) to derive consensus. Deidentified key quotations from the transcripts were selected to illustrate themes and sub-themes (Supplemental Material).

Participants

Twenty-three adults with SSc met study inclusion criteria and participated in one online focus group (Group 1, n = 8; Group 2, n = 8; Group 3, n = 7). Following a total of 3 focus groups including 23 participants, thematic saturation was reached. The mean age of participants was 59 ± 11 years (range 36–77), and 91% (n = 21) were female. Purposive sampling ensured broad and representative participation in terms of SSc disease type (diffuse SSc n = 14, 61%; limited SSc n = 9, 39%), disease duration (<10 years, n = 11, 48%; ≥10 years, n = 12, 52%) and lung involvement (n = 12, 52%). Most participants were currently engaged in exercise (n = 20, 87%) and from New South Wales, Australia (n = 16, 70%). See Table for further details about individual participant characteristics.

Themes

Four themes emerged following thematic analysis of the focus group data, that together constitute barriers and facilitators to exercise in adults with SSc. The themes identified are (a) disease-related and general barriers to exercise, (b) perceived change in personal exercise capacity postdiagnosis, (c) beneficial effects of exercise, and (d) preference for modified supervised exercise. Each theme and subtheme are described in further detail below. Illustrative quotations for each subtheme are included in the Supplemental Material, and a thematic schema summarizing the relationship between the themes are presented in the Figure.

Theme 1-Disease-Related and General Barriers to Exercise. Participants reported several barriers and challenges to engaging in, adhering to, and performing exercise, with this being the predominant theme amongst all 3 focus groups. The subthemes are further illustrated using key quotations in Supplemental Table S2.

Disease-Related Barriers . The cold weather (Q1–5) pertaining to Raynaud's phenomenon (RP), which was a disease manifestation experienced by all participants in our study, was expressed as “a huge factor,” and “…stops me doing a lot,” and affecting exercise. This barrier was described to affect exercise engagement all year around, however RP was described to be particularly problematic during the winter months and was influenced by where participants lived in Australia (i.e., participants who live in Queensland did not report the cold weather as a significant barrier for them to exercise because the average temperature is generally higher than other states in Australia) (27). Skin tightening causing difficultly or the inability to perform exercises that involved gripping objects with their hands (for example, holding a dumbbell or the handle of a gym-based machine), or bearing weight down onto their hands (for example, a floor push-up position), largely attributed to disease manifestations such as hand and/or finger ulcerations, calcinosis, or sclerodactyly (Q8–14). Further, digital ulcerations on the feet were also hindrances to do certain exercise such as meaningful walking. Lung capacity restrictions due to pulmonary fibrosis or interstitial lung disease were reported to cause “shortness of breath” while trying to perform aerobic exercise such as walking long distances and/or walking up a hill (Q15–19), making it difficult to engage in exercise. Fatigue and exhaustion before and resulting from exercise (Q20–22), and skin and tendon tightening or restrictions (Q23–27) were other deterrents to engage in exercise.

General Barriers. The following barriers are categorized independent to the disease-related barriers because they are not considered to be related to manifestations of the disease itself and could apply to people without SSc. Participants transparently expressed “laziness” and a lack of motivation (Q28–32) as reasons for not exercising or being a barrier to exercise. A “new” barrier to exercise expressed strongly by participants was the recent COVID-19 outbreak and subsequent lockdown restrictions (Q33–35). This barrier was twofold; participants were fearful of being exposed to the community and contracting the virus, “I'm being extra careful”; and because the lockdown restrictions meant that their usual exercise routine was compromised. Other barriers included the “expensive” cost of exercise, and difficultly in “accessing” exercise because of a lack of services available for those who live in rural and remote areas of Australia.

Perceived Change in Personal Exercise Capacity Post-diagnosis. A discussion that formed within each of the focus groups focused on a perceived change in their exercise participation and capacity following their diagnosis with SSc (Supplemental Table S3). Participants described exercise(s) that they used to do before they were diagnosed with SSc and commented on how it has significantly differed following their diagnosis (Q1–9). Sport such as tennis, squash, dancing, athletics, or soccer used to be played, and since diagnosis they have stopped because of reasons such as “joints are no good,” “tightness and swelling in legs,” and descriptions such as “but that's all gone now,” “… but no longer,” and “not as strong as I used to be” were made. There was a mixed description between acceptance of this change, and conversely disappointment and frustration that they could no longer do what they used to do. An expectation that they “should” be able to do more than what they can currently do, and expressions such as “I'll cry because I should be able to do this stuff” were made. On the contrary, comments such as “accepting our bodies' limits” and self-talk to remind themselves that “whatever we're doing is sufficient” were described. Remarks were made about the importance of having a “different mental attitude” and changing their own mindset from “I should be able to do it” to “at least I do it” were highlighted. Furthermore, participants suggested to one another that they should “try and pace” and understand when they can “keep going” and when to “pull back.”

Beneficial Effects of Exercise. Participants acknowledged that exercise is beneficial in countering their disease-related barriers and have been categorized into several sub-themes for a more comprehensive view (Supplemental Table S4). An improvement in mental well-being and physical mobility were described to be beneficial from engaging in regular exercise (Q1–5). Participants' also described exercise to be beneficial in improving their lung capacity and fitness (Q6–8) and in improving their energy levels and sleep, with some describing exercise as “invigorating” and expressed that not performing exercise can make them feel “more fatigued” (Q9–11). Participants also described exercise to help reduce overall pain and stiffness, improve circulation, and make them feel “warmer internally,” “feel accomplished,” and that exercising regularly also helped them to “eat healthier” (Q12–16). Participants who performed group exercise expressed that the social aspect was a benefit to exercising, with descriptions such as “it's a good social outlet” and that exercise gives you a sense of “togetherness” (Q17–19), highlighting the social benefit of exercise.

Preference for Modified Supervised Exercise . This theme was categorized into several subthemes according to participants' specific suggestions that would facilitate their engagement in exercise (Supplemental Table S5), however, the consensus was that participants expressed the importance of and preference for modified supervised exercise. Participants conveyed the need for accountability to keep them “motivated” (Q1–3). A lack of interest in going to a gym or performing exercise that was “structured” were described, and participants reported a preference in incidental exercise such as walking or gardening, especially if it's walking outdoors in the fresh air and sunlight, or with a friend. A preference to exercising in a group or with a partner was highlighted, or having a health professional come to their house, again keeping them “accountable.” An emphasis was placed on exercises and/or environments to exercise that were modified to suit their needs (Q4–6). For example, performing Pilates on a reformer bed or standing to perform an exercise, instead of getting on the floor, or turning on the heater before they commence exercise. Suggestions such as having exercise videos online were described as an effective strategy in assisting exercise engagement (Q7–9). For example, using YouTube and performing chair yoga online to engage in exercise at home effectively. This theme was enhanced by the recent COVID-19 pandemic, where, for many, exercising in a gym or clinic was either not an option due lockdown restriction, or they were fearful of being exposed to infection. Another suggestion to facilitate exercise was to come prepared in suitable clothing for the cold (Q10–11), for example, wearing “hoodies,” “gloves,” or “orthopedic boots,” with comments such as “being appropriately clothed adds to the benefit of the exercise.” Participants also held high value in the health professional team having a good understanding about their disease and pointing them in the right direction with exercise (Q12–13). Other suggestions about ways to exercise effectively included finding the right balance, pacing, and knowing “...when to pull back and when to just push yourself.”
