This case controlled study was performed at the Physical Medicine and Rehabilitation outpatient clinic between April 2022 and June 2022. 25 patients who were diagnosed with FS according to the 2010 American College of Rheumatology (ACR) criteria were included in the study. For the control group 25 healthy volunteers with no previous chronic disease history were included . The investigators planed to investigate the relationship between the anxiety level of the FS patients and dysphonia. Thus an acoustic voice analysis (fundamental frequency (F0), jitter, shimmer, noise to harmonic ratio (NHR), harmonic to noise ratio (HNR)) and an aerodynamic analysis (maximal phonation time (MPT)) were performed by an experienced otolaryngologist specialized in voice disorders for evaluation of objective voice quality and function. These analyses were performed on all the volunteers from both groups, and the results obtained were compared between the groups.
Our aim in conducting this study is to determine the relationship between voice disorders and anxiety in patients with fibromyalgia syndrome (FS).
