Article Abstract
Background: The MyotonPro is a portable device for measuring biomechanical and viscoelastic properties in superficial soft tissues. The aims of this study are firstly to validate the MyotonPro compared to a reliable gold-standard frame and secondly to observe the influence of MyotonPro measurement on the total wrist viscoelasticity.
Methods: Three silicone polymers with different elastic properties were assessed with the MyotonPro and with a reference rheometer (Universal Tribometer Mod). Then, a free oscillations method was used to measure the passive elastic and viscous stiffness of the wrist and compared to MyotonPro forearm measurements.
Results: A one-way ANOVA demonstrated the validity of the MyotonPro's stiffness ( = 0.001), decrement ( < 0.001), and relaxation ( = 0.008) parameters for measuring the elastic stiffness () of the three polymers. The MyotonPro parameters demonstrated excellent reliability on the forearm. Proximal and distal anterior myofascial measurements of the MyotonPro were moderately correlated to the elastic stiffness ( = 0.0027-0.0275, absolute = from 0.270 to 0.375) of the wrist while the postero-distal myofascial tissues of the forearm demonstrated a moderate correlation with the viscous stiffness of the wrist ( = 0.0096-0.0433, absolute = from 0.257 to 0.326).
Discussion: The MyotonPro is a valid device for measuring elastic stiffness as well as a portable, affordable, and easy-to-use tool for quantifying the biomechanical properties and viscoelasticity of myofascial tissue in healthy subjects.

Alterations in skeletal muscle morphology and composition are critical factors in cerebral palsy (CP), including changes in passive stiffness and in belly and fascicle lengths. In this study, we quantified the relative contributions of muscle and tendon to passive stiffness across the ankle range of motion in individuals with CP and typically developing (TD) peers. We also investigated morphological factors underlying increased muscle stiffness.

The coexistence of chronic hepatitis B (CHB) and metabolic dysfunction-associated liver disease (MASLD) gained recognition, but the diagnostic performance of non-invasive markers regarding it remains underexplored. This study aimed to evaluate the utility of the FIB-4 index for fibrosis prediction in CHB patients and investigate its performance in the distinct subgroup of CHB-MASLD. A prospective study from 2021 to 2022 included 109 CHB and 64 CHB-MASLD patients.

This study investigates the phenomenon of mode repulsion in Lamb waves propagating through two coupled plates with an elastic interface. Using a spring-based coupling model and the Scaled Boundary Finite Element Method, the dispersion curves of the coupled system are analyzed under various interface conditions-weak coupling, sliding boundary, and perfect coupling. This research highlights how the mechanical stiffness of the interface influences the separation of modes and the emergence of repulsion regions.
