- Abstract
- Background: the term bruxism has circulated since 1907, and can be divided into 2 subgroups; sleep bruxism or nocturnal bruxism and awake or diurnal bruxism. Bruxism can lead to temporomandibular disorder affecting the integrity of the temporomandibular joint and could potentially lead to a reduction in the capsular width. Nevertheless, its etiology and pathophysiology are still unclear. Sleep bruxism can have a strong impact on the dentition of patients not to mention a debilitating effect on an individual's quality of life. Objective: the objective is to investigate to what extent a muscle energy technique on the masseter muscles could influence the capsular width and quality of life in a patient with sleep bruxism. Design: ABAB single-case research design. Method: sleep bruxer' was recruited from the European School of Osteopathy population. The subject was given the Steigerwald Maher TMD disability Index (SMTDI), a quality of life questionnaire, twice a week to fill in before the experiment. A SonoSite M-turbo musculo-skeletal transducer was paced over the TMJ's In a transverse direction. The capsular width was measured between the articular capsule and the condylar laterosuperior surface, using the caliper function. An upper left quadrant protocol was used throughout the research.Results: the muscle energy technique showed effectiveness on the left TMJ capsular width by increasing its measurements from ± 0.10cm to ±0.15cm. On the contrary, no profound effects were found on the right TMJ, nor did the quality of life index show any improvement (stable score of 2). Discussion: research documenting the effects of manual therapy on the capsular width is lacking. The results from this research arouse conflicting conclusions. This study was able to demonstrate that manual therapy can have an impact on the capsular width of the temporomandibular joint. However, there was no evidence in the research linking the capsular width and SMTDI questionnaire. Conclusion: muscle energy technique applied to the TMJ increased the capsular width of one of the joints. The technique does not appear to be clinically useful to treat individuals with sleep bruxism in regards to the scarcity of evidence.
