ABSTRACT
ABSTRACT BACKGROUND AND OBJECTIVES: Musculoskeletal pain (MSP) is related to psychogenic factors and quality of sleep, showing that this triad is a biopsychosocial process. The aim of this study was to analyze an association between poor sleep quality and MSP in adolescents. METHODS: This study has an observational, cross-sectional character, in which 545 adolescents, aged between 11 and 15 years, were analyzed. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), the presence of MSP using the Nordic Musculoskeletal Questionnaire (NMQ), temporomandibular disorder using the Axis II of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and excessive daytime sleepiness using the Epworth Sleepiness Scale (ESS). Pearson Chi-square or Fishers Exact test were used to assess the association between two categorical variables. RESULTS: The prevalence of poor sleep quality, sleep disorders, MSP and excessive daytime sleepiness were, respectively, 66.8, 9.5, 87.5 and 30.5%. An association was observed between the quality of sleep and the number of hours of sleep per night [OR = 1.49; (1.01 to 2.21)], and between sleep disorders and MSP in the upper back [OR=1.9; (1.0 to 3.3)], and the wrists and hands [OR=2.8; (1.4 to 5.7)]. However, there was no association between sleep quality and MSP [OR=1.29; (0.76 to 2.17)]. CONCLUSION: An association was found between sleep disorders and MSP, as well as between the number of hours slept per night and quality of sleep.
RESUMO JUSTIFICATIVA E OBJETIVOS: As dores musculoesqueléticas (DME) possuem relação com fatores psicogênicos e qualidade de sono, evidenciando que essa tríade se refere a um processo biopsicossocial. O objetivo deste estudo foi analisar a associação entre má qualidade de sono e DME em adolescentes. MÉTODOS: Realizou-se estudo observacional, com delineamento transversal, no qual foram analisados 545 adolescentes, na faixa etária entre 11 e 15 anos. A qualidade do sono foi avaliada através do Índice de Qualidade do Sono de Pittsburgh (PSQI), a presença de DME pelo Questionário Nórdico de Sintomas Osteomusculares (QNSO), disfunções temporomandibulares pelo Eixo II dos Critérios Diagnósticos de Pesquisa em Disfunção Temporomandibular (RDC/TMD) e a sonolência diurna excessiva através da Escala de Sonolência de Epworth (ESE). Para avaliar associação entre duas variáveis categóricas, foi utilizado o teste Qui-quadrado de Pearson ou o teste Exato de Fisher. RESULTADOS: A prevalência da má qualidade do sono, distúrbios do sono, DME e sonolência diurna excessiva foram 66,8, 9,5, 87,5 e 30,5%, respectivamente. Observou-se associação entre qualidade do sono e quantidade de horas de sono por noite [OR=1,49; (1,01 a 2,21)], e entre distúrbios do sono e DME na parte superior das costas [OR=1,9; (1,0 a 3,3)] e nos punhos e mãos [OR=2,8; (1,4 a 5,7)]. No entanto, não foi verificada associação entre qualidade do sono e DME [OR=1,29; (0,76 a 2,17)]. CONCLUSÃO: Foi verificada associação entre distúrbios de sono e DME, bem como entre qualidade do sono e quantidade de horas dormidas por noite.
ABSTRACT
Abstract Temporomandibular disorders (TMD) is a term used to describe a set of clinical conditions that may compromise the temporomandibular joint (TMJ) and masticatory muscles and/or associated structures, considered the most frequent cause of orofacial pain of non-dental origin. In recent years, many forms of physical therapy have been used in the treatment of TMD to reduce pain and improve the range of mandibular movement present in this impairment. Among these resources are kinesiotherapy (exercise), electrothermal and manual therapy, acupuncture, training posture, mobilizations, and biofeedback. Objectives To determine if exercises with or without occlusal splints are effective in reducing pain in patients with temporomandibular disorders (TMD) of myogenic origin. Methodology This systematic review was registered in the International Prospective Register of Systematic Reviews (CRD 42019134244). Controlled trials published in PubMed, Scopus, and Cochrane Library following PRISMA guidelines up to April 2022 were randomized and included. The population above 18 years, which evaluated the effectiveness of exercise with or without occlusal splints in reducing pain in patients with TMD of myogenic origin, diagnosed through the Research Diagnostic Criteria for Temporomandibular Disorders, was also included. There was no restriction on the period of publication. Cochrane risk of bias analysis was performed. Results Of the five included articles, all showed a reduction of pain, but without significant differences between the interventions performed. Additionally, studies that evaluated the quality of life and mandibular movements showed a reduction in pain, but no significant differences between therapies. Conclusion The analyzed studies showed no difference in the improvement of pain, quality of life, and mandibular movements between the groups that performed only exercises or the associated treatments.
