Sleep quality and facial pain in fibromyalgia syndrome.

Keywords: Fibromyalgia, sleep apnea, poor sleep quality, snoring, daytime sleepiness, temporomandibular disorder, TMD, TMJ, and facial pain.

Fibromyalgia patients experience many disabilities on a daily basis including poor sleep quality and severe facial pain. A recent study aimed to evaluate sleep conditions and the influence of temporomandibular disorders (TMD) in fibromyalgia patients. Forty women with fibromyalgia were compared to 40 healthy women. Three questionnaires were used to diagnose TMD and to determine sleep quality and pain intensity. Their findings included intense facial pain and poor sleep quality in fibromyalgia patients as well as excessive daytime sleepiness. Dr. Stan Farrell is a Diplomate with the American Board of Orofacial Pain and a member of the American Academy of Dental Sleep Medicine. Dr. Stan Farrell has extensive training in sleep medicine, making him one of the best choices for your sleep apnea and temporomandibular disorder treatment. Dr. Stan Farrell also uses the most effective methods of treatment and works diligently to erase the pain caused by TMD in the lives of his patients. If you or someone you know is experiencing facial pain, daytime sleepiness, and or poor sleep quality caused by fibromyalgia, please schedule a consultation with Dr. Stan Farrell at 480-945-3629 or visit us online at for more information.

Aims: This study aims to evaluate the sleep conditions in fibromyalgia syndrome and the influence of the temporomandibular disorders (TMDs) and fibromyalgia association in self-reported sleep quality. Methodology: Forty female patients with fibromyalgia (FMS) were compared with 40 healthy women [control group (CG)]. Three questionnaires were used (i.e. RDC/TMD to diagnose TMD and to determine pain intensity and disability and Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) to assess sleep conditions). Statistical analyses were performed using the Wilcoxon-Mann-Whitney test to ordinal variables, Student’s t-test to obtain the quantitative total scores of PSQI and chronic pain classification, Spearman’s rho to determine the correlation between facial pain and quality sleep, and Fisher’s exact test for other variables. Results: A moderate correlation between facial pain intensity and low sleep quality was found (rho = 0·56; P<0·0001); however, TMD and FMS association did not show worse sleep quality (P>0·05). Excessive daytime sleepiness was more prevalent in FMS (37·5%; P<0·0001) besides having the worst sleep quality (PSQI = 12·72) compared with CG (PSQI = 4·62). Conclusion: Fibromyalgia patients experience intense facial pain in addition to poor sleep and high disabilities. TMD and FMS association do not appear to worsen this condition; however, facial pain intensity was correlated with low sleep quality.
