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.
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.
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'.
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.
