Brief summary
The aim of the study was to assess and compare the relationship between jaw function, neck disability, sleep quality, fatigue, and headache in patients with myofascial Temporomandibular Disorder (TMD) with Sleep Bruxism (SB) and without (non-SB).
Detailed description
The study was conducted on TMD patients who were willing to participate in the study between January and December 2020. The case-control study included patients diagnosed with myofascial TMD by dental practitioners at regional hospitals referred for physiotherapy. Total of 200 myofascial TMD patients, comprising 91 identified as SB and 109 as non-SB were included in the study. The Jaw Function Limitations Scale (JFLS), Neck Disability Index (NDI), Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale (FSS), and Headache Impact Test-6 (HIT-6) scales and indexes were used for both groups. The effect of Sleep Bruxism (SB) on jaw function, neck problems, sleep quality, fatigue, and tension headache were evaluated. The interactions of these factors and the importance of taking SB into consideration when evaluating and treating patients with TMD were examined.
Interventions
OTHERScales and indexes
Patients with TMD regardless of diagnosis with sleep bruxism were assessed with the Jaw Function Limitations Scale (JFLS), Neck Disability Index (NDI), Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale (FSS), and Headache Impact Test-6 (HIT-6) scales.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Visual Analogue Scale | Baseline | The severity of pain in muscles was measured in centimeters using a 0-10 Visual Analogue Scales (VAS). The scale ranges from 0 = no pain at all to 10 = intolerable pain |
| Jaw Functional Limitation Scale | Baseline | The Jaw Functional Limitation Scale-20 was used to assess jaw function in the masticatory system. The scale consists of a total of 20 items with three constructs. Each item is scored from 0-10, with 0 indicating no restriction and 10, severe restriction. A total of ≥5 indicates jaw function limitation. |
| Neck Disability Index | Baseline | Neck problems were assessed with Neck Disability Index (NDI). It is a scale of 10 sections with total points ranging from 0-50. Higher scores indicate severe pain, and a score of ≥5 indicates a neck disorder. |
| Pittsburgh Sleep Quality Index | Baseline | The sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). The scale comprises a total of 24 items in 7 sub-scales. The total points of the 19 items that score from 0-21, with a total of ≥5 indicating poor sleep quality. |
| Fatigue Severity Scale | Baseline | The effect of fatigue on functional and behavioral aspects was evaluated by the Fatigue Severity Scale (FSS). The total score is calculated as the average of the 9 item scores -the lower the total score, the lower the fatigue level. A cut-off value of ≥4 has been defined for fatigue |
| Headache Impact Test | Baseline | The Headache Impact Test-6 (HİT-6) was used to assess the headache. The 6 items scale evaluating the frequency, the degree of restriction to daily life and social life, and changes in the mood because of headache. The total score 50-59 reflects important impact, and scores ≥60 indicate severe impact. |
