Assessing muscle flexibility and architecture is important for hamstring strain injury (HSI) prevention. We investigated the relationship between shear modulus passive force in muscles at different sites effect of on slope modulus-passive using wave elastography (SWE).
Abstract The present study aims to assess the effect of hip flexion angle on shear modulus adductor longus (AL) muscle associated with passive abduction and rotation. Sixteen men participated in study. For task, angles used were − 20, 0, 40, 60, 80°, 10, 30, 40°. rotation 0 40°, 20° internal rotation, 0° external at extension was significantly higher than that 80° for 30 40° (i.e., P < 0.05). regardless mechanical stress AL extended position. Furthermore, could increase only hip-extended
Purpose: This study used ultrasound shear wave elastography (SWE) to evaluate the mechanical properties of hamstring muscles from cadaveric specimens with knee flexion contractures. Methods: Hamstring for tensile testing were harvested Thiel soft-embalmed cadavers and without contracture. Muscle mounted on a machine. The initial load detected when was applied distal end as slack length. cross-sectional areas muscle at length measured proximal sites using B-mode ultrasonography. Subsequently,...
We investigated the shear modulus-passive force relationship in hip adductor longus (AL) muscles of human cadavers and explored effect muscle architecture on elastic properties AL using wave elastography (SWE). Nine were harvested from a soft, embalmed cadaver. The affixed to custom-built device comprising two clamps, pulley, cable provide passive loads, which increased 0 600 g 60-g increments. modulus was measured proximal (Pro), middle (Mid), distal (Dis) regions. masses anatomical...

This study examined the effect of chest mobilization on intercostal (IC) muscle stiffness using IC shear modulus. Sixteen healthy young men participated two days with a minimum 24 h between stretching and control conditions (SC CC). The tasks were resting breathing deep breathing. modulus activity rib cage circumference measured before after each condition. In SC, was performed for 1 min x 5 sets. CC, breathing, in sitting position, min. decreased significantly (p < 0.05) at maximum...
PURPOSE: External compression with a support belt has been used as means of preventing the development disability and recurrence muscle injury. However, effect external on passive elongation stress not fully demonstrated. Muscle elasticity obtained by ultrasound shear wave elastography is highly reflective force generated (R2 = 0.99). The goal this study was to investigate examine whether local useful in reducing skeletal muscles. METHODS: rectus femoris (RF) 11 healthy men (Age: 22.2 ± 2.7...
