“…Ramazanoglu, Turhan and Usgu, in their study of a large group of patients without TMD, found significant differences in masseter elasticity between genders and some differences in muscle tension. As in our study, he found no difference in masseter muscle stiffness between women and men [23]. However, according to Dietsch et al, female sex is associated with greater stiffness of the orofacial tissues [20].…”

“…There are relatively few studies using myotonometry involving the orofacial muscles [16,[20][21][22][23][24][25][26][27][28]. Hence, there is a need to learn about the biomechanical properties of muscles, not only among healthy patients but also among people with various parafunctions, among people with malocclusion and among patients with TMD pain.…”

It seems extremely important to know the biomechanical properties of the orofacial tissues among patients with increased activity of masticatory muscles, such as bruxism. The aim of this study was to evaluate biomechanical properties of the masseter muscle by using MyotonPRO in adults with probable bruxism and to define gender relations. This study was conducted in the Temporomandibular Disorders Department at Poznan University of Medical Sciences, Poland (June 2021–November 2021) among patients that reported bruxism symptoms The patients underwent a clinical examination, then the biomechanical properties of the masseter muscles were assessed. The MyotonPro measured masseter tone, stiffness and elasticity in 36 patients with a self-assessment of bruxism (18 women and 18 men). Data were collected from relaxed and contracted muscles. In relaxed masseter muscles there were no statistically significant differences between the sexes in muscle tone, stiffness and elasticity. During contraction significant differences were found between the sexes in the tension and the stiffness of the masseter muscles. Moreover, women often experienced headaches in the temporal region and pain in the masseter muscles during palpation. Among patients with a self-assessment of bruxism, accompanying pain was significantly more frequent in women. Male gender was associated with increased muscle tension and stiffness of the contracted masseter muscle.

“…The sample in this study was relatively homogenous comprising predominantly female (68%), young (22.7 ± 4.5 years), and right-handed (91%) subjects. In general, muscle tone and stiffness are reported to be greater in males than females 72 – 74 , however, there are also (partially) conflicting findings 70 , 71 , 75 . Nonetheless, higher muscle tone and stiffness in males may arise due to differences in muscle size, mass, conditioning, and fiber composition between the sexes 124 , 139 , which possibly relate to differences in sex hormones 70 and skinfold thickness 75 .…”

“…For example, practical experience suggests that low-pressure techniques might be preferred for smaller and thinner muscles, whereas high-pressure techniques may be favoured for larger and thicker muscles. Another factor to consider is that changes in muscle properties probably differ between sexes (although the effect seems to vary depending on the treated muscles and measured parameters) 70 – 75 .…”

Musculoskeletal disorders (MSDs) are highly prevalent, burdensome, and putatively associated with an altered human resting muscle tone (HRMT). Osteopathic manipulative treatment (OMT) is commonly and effectively applied to treat MSDs and reputedly influences the HRMT. Arguably, OMT may modulate alterations in HRMT underlying MSDs. However, there is sparse evidence even for the effect of OMT on HRMT in healthy subjects. A 3 × 3 factorial randomised trial was performed to investigate the effect of myofascial release (MRT), muscle energy (MET), and soft tissue techniques (STT) on the HRMT of the corrugator supercilii (CS), superficial masseter (SM), and upper trapezius muscles (UT) in healthy subjects in Hamburg, Germany. Participants were randomised into three groups (1:1:1 allocation ratio) receiving treatment, according to different muscle-technique pairings, over the course of three sessions with one-week washout periods. We assessed the effect of osteopathic techniques on muscle tone (F), biomechanical (S, D), and viscoelastic properties (R, C) from baseline to follow-up (primary objective) and tested if specific muscle-technique pairs modulate the effect pre- to post-intervention (secondary objective) using the MyotonPRO (at rest). Ancillary, we investigate if these putative effects may differ between the sexes. Data were analysed using descriptive (mean, standard deviation, and quantiles) and inductive statistics (Bayesian ANOVA). 59 healthy participants were randomised into three groups and two subjects dropped out from one group (n = 20; n = 20; n = 19–2). The CS produced frequent measurement errors and was excluded from analysis. OMT significantly changed F (−0.163 [0.060]; p = 0.008), S (−3.060 [1.563]; p = 0.048), R (0.594 [0.141]; p < 0.001), and C (0.038 [0.017]; p = 0.028) but not D (0.011 [0.017]; p = 0.527). The effect was not significantly modulated by muscle-technique pairings (p > 0.05). Subgroup analysis revealed a significant sex-specific difference for F from baseline to follow-up. No adverse events were reported. OMT modified the HRMT in healthy subjects which may inform future research on MSDs. In detail, MRT, MET, and STT reduced the muscle tone (F), decreased biomechanical (S not D), and increased viscoelastic properties (R and C) of the SM and UT (CS was not measurable). However, the effect on HRMT was not modulated by muscle–technique interaction and showed sex-specific differences only for F.Trial registration German Clinical Trial Register (DRKS00020393).
