Ankle-angle-dependent shear wave velocity of the Achilles tendon and triceps surae during passive dorsiflexion in runners with Achilles tendinopathy
Purpose This study aimed to determine whether runners with mid-portion Achilles tendinopathy (Achilles tendinopathy runners [ATR]) show altered ankle-angle-dependent mechanical behavior of the Achilles tendon and triceps surae muscle–tendon unit during passive dorsiflexion. Methods Twelve ATR and 11 control runners (CON) participated in this study (ATR: age 43.9 ± 12.0 years, running distance 38.3 ± 22.3 km/week; CON: age 41.2 ± 13.7 years, runni…
Determining the Minimal Number of Passive Hip and Knee Joint Movement Repetitions Recommended for the Stiff Rectus Femoris Muscle Due to Osgood–Schlatter Disease
Background/Objectives: Osgood–Schlatter disease (OSD) is a common overuse condition in adolescents characterized by increased stiffness of the rectus femoris muscle, which contributes to pain and functional limitations around the knee. We investigated whether repeating 10 min passive joint movements of the hip and knee produces additional immediate reductions in elevated rectus femoris (RF) stiffness in adolescents with OSD. Methods: Fifteen pati…
Angle-specific stiffness profiles of the achilles tendon and Triceps surae muscles
The stiffness of the triceps surae (TS) muscles during passive stretch has been increasingly studied using shear wave elastography (SWE). However, the continuous behavior of the Achilles tendon (AT) and its interaction with the TS muscles remain poorly understood, limiting understanding of tissue mechanics. This study aimed to characterize the angle-specific stiffness profiles of the individual TS muscles-the medial gastrocnemius (MG), lateral ga…
The Relationship Between L2 Interactional Competence and Proficiency
The relationship between L2 linguistic skills and the ability to use language for social purposes is still under-explored. While previous research suggests that higher proficiency coincides with better pragmatic and interactional performance, incongruities are also apparent with some low-proficiency learners being able to communicate effectively, and some high-proficiency learners showing pronounced weaknesses in interactional performance. In thi…
What scores from monologic speaking tests can(not) tell us about interactional competence
The overarching aim of the study is to explore the extent to which test takers’ performances on monologic speaking tasks provide information about their interactional competence. This is an important concern from a test use perspective, as stakeholders tend to consider test scores as providing comprehensive information about all aspects of L2 competence. One hundred and fifty test takers completed a TOEFL iBT speaking section consisting of six mo…
