Shear wave elastography for assessing rectus femoris stiffness: a study on the interaction and reliability of body position and contraction state

Puntos clave

Stiffness assessment focuses on rectus femoris, highlighting the interaction between body position and contraction state.
Findings show the need for standardized measurement in stiffness evaluation using shear wave elastography, offering a foundational approach.
Assessment used observational methods to detail the interplay of posture and muscle contraction on measurements.
Implications suggest that standardized protocols may enhance reliability in biomechanics, sports science, and rehabilitation fields.

Resumen

This study establishes a methodological basis for assessing the stiffness of the RF, identifying posture and contraction as key factors. Our findings underscore the need for standardized measurement and support the future application of SWE in biomechanics, sports, and rehabilitation.
