Sixteen participants with a history of trigeminal neuropathic pain (<jats:styled-content style=\"fixed-case\">TNP<\/jats:styled-content>) and 15 age\u2010 and gender\u2010matched healthy controls had jaw movements recorded during open\/close, free gum chewing and chewing at standardised rates. All completed the Pain Catastrophising Scale (<jats:styled-content style=\"fixed-case\">PCS<\/jats:styled-content>), the Pain Self\u2010Efficacy Questionnaire (<jats:styled-content style=\"fixed-case\">PSEQ<\/jats:styled-content>), and the Depression, Anxiety and Stress Scales (<jats:styled-content style=\"fixed-case\">DASS<\/jats:styled-content>). Velocity and amplitude for open\/close and chewing, as well as variability, bias and mean square error for open\/close jaw movements were compared between groups. Spearman's rank correlation coefficient was used to relate kinematic variables with psychological variables. Statistical significance: <jats:italic>P\u00a0<\/jats:italic>&lt;\u00a00\u00b705. There were no significant differences in mean jaw velocity and amplitude between the <jats:styled-content style=\"fixed-case\">TNP<\/jats:styled-content> and control groups during the open\/close jaw movements or free or standardised chewing. In comparison with control, the <jats:styled-content style=\"fixed-case\">TNP<\/jats:styled-content> participants exhibited significantly greater variability, bias and\/or mean square error during slow and\/or fast opening, and significantly greater variance in velocity and\/or amplitude during free and standardised chewing. There were significant negative correlations between <jats:styled-content style=\"fixed-case\">PCS<\/jats:styled-content> scores and velocity and\/or amplitude of free and\/or standardised chewing. This exploratory study suggests that individuals with a history of pain have altered patterns of jaw movements in comparison with asymptomatic control participants and that catastrophising may play a role in the manifestation of these altered jaw movements.<\/jats:p>","DOI":"10.1111\/joor.12220","type":"journal-article","created":{"date-parts":[[2014,8,22]],"date-time":"2014-08-22T06:35:10Z","timestamp":1408689310000},"page":"18-26","source":"Crossref","is-referenced-by-count":15,"title":["Jaw movements in patients with a history of pain: an exploratory study"],"prefix":"10.1111","volume":"42","author":[{"given":"M.","family":"Bhaskaracharya","sequence":"first","affiliation":[{"name":"Jaw Function and Orofacial Pain Research Unit Faculty of Dentistry University of Sydney Westmead NSW Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
