Churg-Strauss syndrome (CSS) is an eosinophilic vasculitis, which involves multiple organ systems, including the lungs, heart, skin and neuromuscular system. Since CSS is an inflammatory disease, administration of systemic glucocorticoids has been a standard therapy for the disease. However, even if the inflammation has been controlled by glucocorticoids, neuromuscular disorders often do not improve. Thus, we aimed in this study to evaluate the efficacy of low-intensity exercise with blood flow restriction (BFR) on CSS-induced muscle atrophy and weakness. A 40-year-old female ballet dancer with CSS-induced muscle atrophy in her right lower leg underwent a 14-wk training program, which consisted of low-intensity resistance exercise (plantar flexion, leg extension and leg curl) and walking exercise with BFR. To measure cross-sectional area (CSA) of lower leg muscles, magnetic resonance images (MRI) of both lower legs were obtained before and after the 14-wk training period. After the 14-wk training period, muscle CSA of the right lower leg showed 29.1% increase, though it was still 23.4% smaller than that of the left side. In conclusion, this case study showed that low-intensity exercise with BFR induced muscle hypertrophy in a female ballet dancer with CSS. It is suggested that low-intensity exercise with BFR can be a valuable rehabilitation tool for patients with CSS to counteract muscle atrophy and weakness.
