Summary: This article systematically reviewed the literature on the change in muscle stiffness as measured by ultrasound elastography in stroke survivors. The analysis of 29 relevant studies showed that ultrasound elastography has good validity in assessing muscle stiffness in stroke survivors and identified factors that affect muscle stiffness.

Summary: This study investigates the impacts of various physical parameters and different sports on patellar tendon stiffness in professional athletes using shear wave elastography (SWE). The results show no significant differences in patellar tendon stiffness according to gender, age, body mass index (BMI) and type of sport. Oral contraceptive (OC) intake may have some impact on patellar tendon stiffness in female athletes, but not significantly.

Summary: The study aimed to evaluate the reliability of shear wave elastography in assessing anterior and middle scalene muscles in healthy adult subjects. Results showed a positive correlation between the left middle scalene muscle and body mass index, as well as a significant difference between the right and left middle scalene muscles.

Summary: This study aimed to investigate the sonoelastographic features of the sartorius muscle and its relation to demographic factors. The results showed a positive correlation between the elastic modulus of the right sartorius muscle, weight, and body mass index, serving as a reference point for evaluating sartorius muscle stiffness in future research.

Summary: Individual activation strategies during hamstring strengthening exercises have not been thoroughly explored for their consequences on muscle damage distribution. This study found a significant correlation between the distribution of activation and the distribution of damage in the hamstring muscle heads during maximal eccentric contractions.

Summary: The study focuses on quantitatively measuring the elastic degree of anisotropy (DoA) in muscle, kidney, breast, and other organs using the ARFI PD as a measurement. The results demonstrate the feasibility of using ARFI PD to accurately measure the elastic DoA in biological tissues.

Summary: Objective Shear wave elastography (SWE) was used to assess the stiffness of muscles and tendons in the lower limb of professional (PG) and semiprofessional female athletes (SG). The results showed that professional female athletes had higher stiffness values in muscles and tendons of the lower limb compared to semiprofessional female athletes, except for the patellar tendon. Understanding these differences is important for diagnosing tendon pathology and injuries. Musculoskeletal SWE can provide significant benefits in sports medicine, rehabilitation, and preventive medicine.

Summary: This study investigated the effect of knee joint angle on the mechanical properties of the vastus medialis (VM) and vastus lateralis (VL) during voluntary contractions. The results showed that the Young's modulus of the VM did not differ significantly among torque levels and knee angles, while the Young's modulus of the VL was significantly higher at 25% muscle contraction for a knee angle of 100 degrees compared to 75% muscle contraction for the same knee angle, and it was also higher at 25% muscle contraction for a knee angle of 100 degrees compared to 50 degrees.

Summary: This study assessed muscle mass and function in elderly patients with type 2 diabetes using ultrasound and shear wave elastography. Various clinical indicators were measured, and the thickness, cross-sectional area, and shear wave elastography values of the rectus femoris muscle were also measured. The study found independent predictors for sarcopenia and established a diagnostic model with high accuracy.

Summary: The study reviews the use of ultrasound elastography techniques for evaluating muscle stiffness caused by spasticity in patients with central nervous system diseases. While showing some limitations in spasticity assessment, the technique holds promise as a diagnostic tool for designing treatment plans and monitoring treatment effectiveness.

Summary: This study assessed the application of wave elastography in muscle stiffness assessment and compared the measurement results of two different devices. The study found significant differences in stiffness variability among different muscle regions, with the 75% location having the lowest variability and highest agreement, suggesting its use in future stiffness assessments.

Summary: The study found moderate to strong correlations between MyotonPRO and SWE measurements of lower limb muscle stiffness during resting and active voluntary contraction. Muscle stiffness was generally higher in men compared to women at rest and during contraction, except for the TA muscle. The instruments showed good intra-rater reliability and moderate to good correlations between measurements at rest and during active voluntary contraction.
