All participants used a portable single-channel EMG device (Medotech A\/S) for four nights. There was no significant difference in EMG activity between craniofacial pain (24.5 \u00b1 17.9 events\/hr) and no painful conditions (19.7 \u00b1 14.5), or between TTH (20.8 \u00b1 15.0) and healthy control individuals (15.2 \u00b1 11.6, p &gt;.050). There were positive correlations between EMG activity and number of painful muscles (r = 0.188; p = 0.044), characteristic pain intensity (r = 0.187; p = 0.046), McGill Pain Questionnaire (r = 0.251; p = 0.008), and depression scores (r = 0.291; p = 0.002). Patients with painful conditions had significantly higher night-to-night variability compared with pain-free individuals (p &lt; 0.050). This short-term observational study suggests that there are no major differences between patients with different craniofacial pain conditions and pain-free individuals in terms of jaw-muscle EMG activity recorded with a single-channel EMG device during sleep. However, some associations may exist between the level of EMG activity and various parameters of craniofacial pain. Longitudinal studies are warranted to further explore the relationship between sleep bruxism and craniofacial pain.<\/jats:p>","DOI":"10.1177\/0022034512446340","type":"journal-article","created":{"date-parts":[[2012,4,19]],"date-time":"2012-04-19T20:39:55Z","timestamp":1334867995000},"page":"562-567","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":51,"title":["Craniofacial Pain and Jaw-muscle Activity during Sleep"],"prefix":"10.1177","volume":"91","author":[{"given":"W.","family":"Yachida","sequence":"first","affiliation":[{"name":"Department of Oral Rehabilitation, Graduate School of Dental Medicine, Hokkaido University, Sapporo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.E.","family":"Castrillon","sequence":"additional","affiliation":[{"name":"Section of Clinical Oral Physiology, Department of Dentistry, Aarhus University, Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Baad-Hansen","sequence":"additional","affiliation":[{"name":"Section of Clinical Oral Physiology, Department of Dentistry, Aarhus University, Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Jensen","sequence":"additional","affiliation":[{"name":"Danish Headache Center, Department of Neurology, Glostrup Hospital, University of Copenhagen, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Arima","sequence":"additional","affiliation":[{"name":"Department of Oral Rehabilitation, Graduate School of Dental Medicine, Hokkaido University, Sapporo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Tomonaga","sequence":"additional","affiliation":[{"name":"Department of Oral Rehabilitation, Graduate School of Dental Medicine, Hokkaido University, Sapporo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Ohata","sequence":"additional","affiliation":[{"name":"Department of Oral Rehabilitation, Graduate School of Dental Medicine, Hokkaido University, Sapporo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Svensson","sequence":"additional","affiliation":[{"name":"Section of Clinical Oral Physiology, Department of Dentistry, Aarhus University, Aarhus, Denmark"},{"name":"Center for Functionally Integrative Neuroscience (CFIN), MindLab, Aarhus University Hospital, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2012,4,18]]},"reference":[{"key":"bibr1-0022034512446340","first-page":"342","volume":"22","author":"Abe S","year":"2009","journal-title":"Int J Prosthodont"},{"key":"bibr2-0022034512446340","unstructured":"American Academy of Sleep Medicine (2005).
