Pharmacological management is often inadequate, and evidence on exercise is limited. This study aimed to evaluate the effects of a tailored exercise programme on pain and fatigue in people with SSc (PwSSc).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This European multicentre randomised controlled trial (n=6) recruited 170 PwSSc (89% limited cutaneous SSc), randomised to an exercise intervention group (EIG) or usual care group (UCG). The EIG completed a 12-week, twice-weekly supervised programme combining 30\u2009min of high-intensity interval training (HIIT) and 15\u2009min of resistance training (RT), in addition to usual care. The UCG received usual care alone. Outcomes were assessed at baseline, 12 weeks (primary endpoint) and 24 weeks, with pain and fatigue as primary outcomes, and QoL, depression, functional ability, musculoskeletal strength\/endurance and cardiorespiratory fitness as secondary outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>At 12 weeks, the mean group differences for the primary, fatigue (\u221210.4 (95% CI 19.4 to \u22121.4), p&lt;0.05) and pain (0.48 (95% CI 0.21 to 0.76), p&lt;0.05), secondary, depression (p&lt;0.001), QoL and self-reported function (p&lt;0.05) and exploratory outcomes musculoskeletal strength and endurance (p&lt;0.01), and cardiorespiratory fitness (p&lt;0.001) were significantly improved in EIG compared with UCG.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>A 12-week supervised combined upper body exercise programme can improve pain, fatigue, depression, QoL, function, strength and cardiorespiratory fitness in PwSSc.
