Forty patients with a diagnosis of FMS were divided randomly into two groups. Twenty one subjects in first group received supervised breathing exercises and also physiotherapy and rehabilitation for a total of three weeks, five sessions per week, while nineteen subjects in second group received home-based breathing exercises and also physiotherapy and rehabilitation.Outcomes were Visual Analog Scale (VAS) for pain, Fibromyalgia Impact Questionnaire (FIQ) for functional capacity, 6-minute walk test (6-MWT) for physical performance, and Pittsburgh Sleep Quality Index (PSQI) for sleep quality.It was found that there were significant improvements in FIQ and PSQI scores for post-treatment compared to pre-treatment in both groups (p<0.05). VAS score was statistically reduced in the first group, but not in the second group. In addition, no statistically significant differences on physical performance were found in both groups. A comparison of the two groups showed no statistically significant difference for VAS, FIQ, 6-MWT, and PSQI scores (p>0,05).Our results showed that both supervised and home-based breathing exercise programs have beneficial effects on FIQ, PSQI and have no effects on 6-MWT. In pain management, only supervised breathing exercise seems to have positive effects.
