Design outcomes

Primary

MeasureTime frame
Expected outcome 1: There is a difference between the TMD diagnostic groups regarding the mandible, depression and pain limitations assessed by the RDC / TMD Axis II (Kruskal Wallis Test).;Outcome found 1: 1: Limitations related to mandibular function, depression and pain did not present differences regarding TMD diagnoses and muscular impairment. Depression was different in terms of joint impairment and pain in the presence of bruxism. Women with no joint impairment presented higher depression scores, 0.90 (0.55 - 1.50), compared to those with monoarticular involvement, 0.37 (0.15-0.83), (p = 0.008) . Women with biarticular impairment, 0.80 (0.45 - 1.60) had a higher rate of depression compared to monoarticular impairment, 0.37 (0.15 - 0.83), (p = 0.023). The group with bruxism reported a greater degree of pain at the time, 3.0 (2.0 - 6.0), than the group without bruxism, 0 (0 - 2.0), (p = 0.001), as also showed a greater impairment in the ability to work through pain, 1.5 (0 - 3.0), compared to the group without reporting bruxism, 0 (0 - 0.75), (p = 0.039).;Expected outcome 2: It presents difference between TMD diagnostic groups regarding postural angles, range of cervical movement and surface electromyography (Kruskal Wallis Test).;Outcome found 2: The muscular TMD group, and the mixed TMD group, had lower right ROMs, 69.00 (64.5 - 79.3) and 78.60 (71.6 - 85.0) respectively, compared to joint diagnosis, 93.15 (91.3 - 95.0), p = 0.037 and p = 0.033. The myofascial pain group, 82.95 (66.0 - 88.0) and myofascial pain with aperture limitation 77.00 (67.8 - 79.6) had a lower cervical rotation ROM to the right compared to the non-muscle group 93.15 (91.3 - 95.0), p = 0.049 and p = 0.028, respectively. ;Expected outcome 3: Lower cervical range of motion, worse posture and difference in surface electromyography (Kruskal Wallis Test).;Outcome found 3: Participants who did not report bruxism had lower ROM in left cervical rotation, 75.95 (68.35 - 80.90), compared to the br

Secondary

MeasureTime frame
Expected outcome 4: Correlation between limitations related to mandibular function with postural changes, range of cervical joint motion and surface electromyography (Spearman Test).;Outcome found 4: The variables related to posture, the EMGs showed no correlation with the limitations related to the mandibular function. There was a weak negative correlation between the lateral tilt ADM to the right of the cervical (? = -0.315 - p = 0.026).;Expected outcome 5: Correlation between limitations related to mandibular function with depression and pain assessed by RDC / TMD Axis II (Spearman Test).;Outcome found 5: There was a positive correlation between depression (? = 0.333 - p = 0.015), pain interference in daily activities (? = 0.298 - p = 0.036) and leisure 0.341 - p = 0.015) with limitations related to mandibular function.
