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…
Can online interactions reduce loneliness in young adults during university closures in Japan? The directed acyclic graphs approach
As a countermeasure to the increased loneliness induced by the COVID‐19 pandemic‐related university closures, universities provided students with online interaction opportunities. However, whether these opportunities contributed to reducing loneliness during the university closures remains unclear, as previous studies have produced contradictory findings. We conducted a nationwide cross‐sectional survey. Data were collected on demographics, socia…
