O impacto da síndrome da fibromialgia na musculatura mastigatória e cervical: análise eletromiográfica, ultrassonográfica, força de mordida e eficiência mastigatória
Аннотация:Fibromyalgia syndrome is characterized by chronic and diffuse muscle pain in at least eleven points of the human body (tender points), morning stiffness, fatigue, sleep disturbances, extensive pain symptoms in the face, which is mainly manifested in the masticatory muscles, temporomandibular joint and ear region.The aim of this study was to analyze the masticatory (masseter and temporal) and cervical (sternocleidomastoid and trapezius) muscles in women with diagnosis of fibromyalgia syndrome.Sixty-eight women aged between 40 and 60 years participated in this research.They were divided into two distinct groups: FG: fibromyalgia syndrome (n = 34) and CG: healthy control (n = 34).The Myosystem-Br1 electromyography was used to analyze the EMG activity.The thicknesses of the masticatory and neck muscles were acquired by ultrasound Sonosite Titan.The maximum molar bite force was obtained using a digital force gauge Kratos.The data of EMG activity, muscles thickness and maximal molar bite force were tabulated, standardized and subjected to statistical analysis (SPSS 21.0).There were statistically significant differences (p≤ 0.05) between FG and CG at all mandibular postural conditions, chewing, muscle thickness and molar bite force, with lower average data for FG.Based on the results of this research, the authors concluded that women with fibromyalgia syndrome have alterations in the stomatognathic system.
