Syfte. Att retrospektivt undersöka relationen mellan central sensitisering i det orofacialaområdet och refererad smärta, som kliniskt fynd, samt psykosociala faktorer hos patienter medDC/TMD-muskeldiagnosen myofasciell smärta med refererad smärta (MPR). Studien syftadeäven till att undersöka skillnader gällande psykosociala faktorer mellan patienter somdiagnostiserats med DC/TMD muskeldiagnoserna myofasciell smärta med refererad smärta(MPR), lokal myalgi (LM) och patienter med orofacial smärta eller käkdysfunktion men ejkäkmuskeldiagnos (WMD) som kontrollgrupper.Material och metod. Information från 85 patienters DC/TMD-undersökning utförd påOrofaciala smärtenheten vid Malmö högskola mellan september 2012 till årsslutet 2013insamlades retrospektivt. Undersökta variabler inkluderade smärtintensitet, smärt-relateraddysfunktion, psykosociala faktorer (depression, ångest och stress) samt refererad smärta.Patienterna indelades i grupper baserade på muskeldiagnos enligt DC/TMD samt utbredning avsmärta. Non-parametrisk statistik användes och P < 0,05 betraktades som signifikant.Resultat. Patienter med MPR uppvisade en signifikant korrelation mellan totala antaletrefererade smärtlokalisationer och smärt-relaterad dysfunktion (rs = 0,43, n = 49, p = 0,002),depression (rs = 0,32, n = 49, p = 0,023) och stress (rs = 0,39, n = 49, p = 0,006). Patienter meden generell smärtutbredning uppvisade en signifikant högre grad av stress (p = 0,020) samt flerantal refererade smärtlokalisationer (p = 0,019) jämfört med patienter med lokal och/ellerregional orofacial smärta.Konklusion. Studien indikerar att grad av central sensitisering kan bedömas med hjälp avutbredningen av refererad smärta, undersökt enligt DC/TMD, hos patienter med diagnosenmyofasciell smärta med refererad smärta i det orofaciala området. Studien kunde inte påvisaskillnader gällande psykosociala faktorer mellan de undersökta grupperna. / Objective. The aim of this study was to retrospectively investigate the relation between referredpain, as a clinical finding, and psychosocial factors versus central sensitization in patients withmyofascial pain with referral (MPR) as assessed according to DC/TMD. The study also aimedto investigate differences regarding psychosocial factors between patients demonstratingmyofascial pain with referral (MPR) and patients diagnosed with the DC/TMD muscle diagnoselocal myalgia (LM) as well as OFP/TMD patients without masticatory muscular diagnose(WMD) as control patients.Material and methods. Patients’ medical records of 85 patients examined at the Orofacial PainUnit at Malmö University during September 2012 till the end of 2013 were retrospectivelyexamined for DC/TMD data. Examined variables included pain intensity, pain-related disability,psychosocial factors (depression, anxiety and stress) and referred pain. The patients weredivided into groups based on DC/TMD muscle diagnosis as well as extension of pain. Nonparametricstatistics were used and a probability level of P < 0.05 was considered as significant.Results. Patients with MPR demonstrated significant correlations between the total number ofreferred pain sites and disability score (rs = 0.43, n = 49, p = 0.002), depression (rs = 0.32, n =49, p = 0.023) as well as stress (rs = 0.39, n = 49, p = 0.006). Patients with generalized paindistribution demonstrated a significantly higher degree of stress (p = 0.020) as well as highernumber of referred pain sites (p = 0.019) than patients with local and/or regional orofacial pain.Conclusion. This study indicates that the degree of central sensitization can be estimated bythe extent of referred pain, as assessed according to DC/TMD, in patients with myofascial painwith referred pain in the orofacial region. This study could not detect a difference inpsychosocial factors between the three groups, myofascial pain with referral (MPR), localmyalgia (LM) and no masticatory muscle diagnosis (WMD).
