“…In the study conducted by Herman et al, the mean stiffness of the masseter muscle in 176 healthy volunteers was 10.0± 4.3 kPa [38]. The study by Olchowy et al conducted on 140 healthy adults determined the elasticity to be 10.67 ± 1.77 kPa [39]. The average value obtained in the pediatric population in the present study was 6.37 ± 0.77 kPa, which was about one third less than in adults.…”

In children, the quality and muscle function are altered in many pathologic conditions, including temporomandibular disorders. Although several methods have been used to evaluate muscle tonus, none became a golden standard. Moreover, the masseter muscle characteristics in children have not been investigated to date. This study aimed to measure the stiffness of the masseter muscle using shear-wave elastography in healthy children. We enrolled 30 healthy children (mean age 10.87 ± 3.38 years). The stiffness of masseter muscles was measured with shear wave elastography. Stiffness for the total sample was 6.37 ± 0.77 kPa. A comparison of the measurements did not show significant differences between the right and the left masseter muscles (left—6.47 ± 0.78 kPa; right—6.24 ± 0.76 kPa; p = 0.3546). A significant difference was seen between boys and girls (boys—5.94 ± 0.50 kPa; girls—6.63 ± 0.80; p = 0.0006). Shear-wave elastography is a promising diagnostic tool. It may help to detect changes in the stiffness of the masseter muscle and draw attention to pathological processes within the jaw muscles. Directions for further research shall include determining stiffness values in pathological conditions and the impact of biological and functional factors on the stiffness of the masseter muscle.

“…Ultrasonographic reference values for different muscles remain scarce, and limited to relatively small study samples [21][22][23][24][25][26] . The use of different measurement techniques and study populations, and the investigation of different muscles and muscle parameters within this limited number of studies, make it very difficult to extrapolate their results to the general population 14 .…”

Objectives: Muscle ultrasound is gaining importance as a measurement tool to evaluate sarcopenia in daily clinical practice. This study sought to collect reference values of the biceps brachii (BB) in healthy subjects, and to correlate them to bioelectrical impedance analysis (BIA) and hand grip strength (HGS). Methods: Ultrasound was used to measure muscle thickness (MT), cross-sectional area (CSA) and muscle stiffness (EG). Lean mass (LM), fat mass (FM) and phase angle (PhA) were measured by BIA. HGS was measured using a Jamar dynamometer. Intra-rater reliability was calculated using intraclass correlation (ICC). Correlations were investigated using Pearson correlation (PCC). Results: One-hundred-twenty-three Caucasian individuals (51 male and 72 female subjects) between 18 and 69 years old were included. ICC for ultrasound was 0.99 (CI 0.98-0.99). LM, PhA and HGS showed significant correlations with MT and CSA in the entire population (PCC>0.684). These correlations were more significant and stronger in male than in female subjects (PCC>0.419 and >0.279 resp.). Significant correlations with respect to FM and EG were seen exclusively in female subjects. Conclusion: Significant correlations were observed between parameters of muscle quantity measured by ultrasound, BIA and HGS. Intra-rater reliability was excellent. Future studies in larger populations are needed to clarify the observed gender differences.

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.
