COVID-19 pandemic and exercising: a cross-sectional study with 1156 patients with fibromyalgia.

OBJECTIVE: The aim of this study was to analyze the effects of pandemic in the exercising practice and impact of the disease in patients with Fibromyalgia. METHODS: This is a cross-sectional, Internet-based survey answered by 1156 individuals with Fibromyalgia diagnosis. Questions were on epidemiology, social distancing habits, and exercise practice before and after COVID-19 pandemic, including subtypes of exercises (for resistance, flexibility, balance, and strength). The Fibromyalgia Impact Questionnaire was applied. RESULTS: In the whole sample, 57.7% of individuals practiced exercises before pandemic; during pandemic, only 34.8% practiced and 39.6% left this practice. Among those taking quarantine (n=440), 52.9% used to do exercises prior to pandemic; in the pandemic, 28.1% (reduction of 53.2%). The median Fibromyalgia Impact Questionnaire among those who practiced exercises in the pandemic was 73.6 (61.1-83.2) and that among those who did not was 80.4 (71.9-86.9), with p<0.0001. The Fibromyalgia Impact Questionnaire did not change according to the type of physical exercise (p=0.27). CONCLUSION: A high proportion of patients with Fibromyalgia stopped exercising during COVID-19 pandemic; as a result, the impact of the disease during this period was worse among those not practicing exercises.
