PurposeConsidering the fascial continuity and its biomechanical characteristics, the purpose of this study was to assess the change in muscular stiffness (Dm) of the upper trapezius muscles after the application of myofascial induction therapy (MIT) to the masticatory muscles of musicians.MethodsThis was a pre-posttest design involving one treatment.SubjectsThe total sample was 33 subjects (n = 33). The experimental group comprised 18 violin, viola, and woodwind players, and the control group was comprised of 15 non-musicians. The outcome measures included pre-posttest measurements with tensiomyography of the upper trapezius (muscle stiffness, Dm), and baseline neck disability (Neck Disability Index), and pain (SF-36 questionnaire). The experimental group received MIT for 5 minutes on each side of the lateral pterygoid muscle. The control group assumed a supine position for 10 minutes.ResultsAfter the intervention, there was a significant difference in Time per Group (F = 2.896, p = 0.034, ƞ2p = 0.367, and w = 0.755). There were statistically significant differences in pre-post and side-by-side analyses for the Dm of the upper trapezius in the experimental group as well as between the two groups.ConclusionMIT of the lateral pterygoids is effective in decreasing upper trapezius stiffness as measured by an increase in the Dm measured by tensiomyography. The greatest change occurred in musicians with a lower percentage of Neck Disability Index at baseline.
