Fatigue in Sjögren's Syndrome: a Randomized Controlled Trial of Combined Non-pharmacological Therapeutic Strategies
Unexplained fatigue is a frequent (60-70%) chronic complaint in Sjögren's syndrome (SjS) with a clear unmet therapeutic need, despite the recommendation of adapted physical activity (APA) programs, which are effective and feasible, but only to some extent. Hence, other therapeutic approaches, such as Acupuncture (ACU) or transcutaneous vagal nerve stimulation (tVNS), have been evaluated during the past years, with varying degrees of success in alleviating fatigue. FESSONA has been designed as a randomized controlled monocentric trial, aiming at comparing the effects of 3 different programs on fatigue in SjS: APA alone, APA+ACU and APA+tVNS. Relevant controls will be included as well (sham ACU and simulated tVNS). Multiple fatigue and SjS-related features will be measured before (at inclusion) and after (week 12) the intervention, as well as at week 24 and 48, to evaluate the short- and long-term impact of each program. Tolerance and feasibility will also be evaluated.
