EVALUATION OF THE RELATIONSHIP BETWEEN VOICE DISORDERS AND THE DISEASE ACTIVITY IN PATIENTS WITH FIBROMYALGIA SYNDROME

Methods: This study included 23 patients with fibromyalgia and 24 healthy subjects. Pain was assessed with visual analog scale, anxiety and depression were evaluated with Beck Anxiety Inventory and Beck Depression Inventory, the disease activity and quality of life were assessed with Fibromyalgia Impact Questionnaire, and fatigue were evaluated fatigue severity scale in patients with FMS. In addition, perceptual voice analysis, aerodynamic analysis and acoustic analysis was administrated to all patients with FMS.

Results: The mean age was 51.47±11.60 years in group of FMS and 33.84±17.14 years in the control group. There was no significantly difference between mean age values of control and patient groups. The average duration of symptoms was 43.20±19.41 months in FMS patients. The mean of VAS score was 66.00±11.34, the average fatigue severity scale was 6.20±1.26, FIQ average was 66.18±16.43, Beck Depression Inventory mean value was 30.13±12.52, Beck Anxiety Inventory mean value was 24.33±12.22. VHI-total value was higher in the FMS group but there was no significantly difference. However, usage of voice and usage of songs sound values were significantly lower in the FMS group than controls. Maximum phonation time and SPLmax were significantly lower than the control group. Although F0min and F0max were lower in patients with FMS than the control group, the differences were not statistically significant. There was no statistically significant difference between the control group and the FMS group for Jitter % and DSI average.

Conclusion: Laryngeal function was almost normally in patients with fibromyalgia syndrome, but respiratory muscle dysfunction might lead to dysphonia via affected sound production. Keywords : Fibromyalgia, Acousticvoiceanalysis, Aerodynamicevaluation, Voice handicapindex
