Tinnitus is an endogenous sonorous sensation, or rather, it is any sound perceived by the individual without the existence of an external acoustic stimulation (1,2). Thus, their presence in tinnitus patients should be more investigated as a possible etiologic or adjuvant factor. Conclusion: Myofascial trigger points were surprisingly common in tinnitus patients and evoked a high rate of tinnitus modulation during digital pressure. There was an association of laterality between the ear with worst tinnitus and the side of the body with more trigger points in 56.5% of the cases (p< 0.001). The rate of tinnitus modulation was significantly higher at the same side of the trigger point subject to examination in 6 out of 9 muscles. Among them, 55.9% reported temporary tinnitus modulation during trigger point's digital pressure. Results: The presence of trigger points was observed in 72.3% of tinnitus patients (OR= 4.87 p< 0,001). The intensity of tinnitus was examined through a numeric scale from 0 to 10, assuming as tinnitus modulation the immediate increase or decrease of at least one point in the scale and/or changes in the type of sound. All of them underwent an evaluation protocol and digital pressure, in order to search for trigger points in 9 bilateral muscles in the head, neck and shoulder girdle. Method: In this case control study 94 subjects with tinnitus, and 94 symptomless were analyzed. Objectives: Investigate a possible association between tinnitus and myofascial trigger points and their capacity to modulate tinnitus.
However, this issue is poorly explored in the literature. Introduction: Some patients suffering from tinnitus may have their symptom influenced by myofascial trigger points located in the head and neck muscles.
