The Achilles tendon (AT) comprises three subtendons whose relative locations, and respective lines of action, vary individually. This study was aimed to demonstrate the efficacy a novel method, combining Ultrasound electrical STIMulation (USTIM), identify in vivo location individual cross-sections AT. We individually stimulated triceps surae muscle heads imaged localized tissue movement on transverse plane 1 cm proximal calcaneus using B-mode ultrasonography. Movement induced by stimulation...
Abstract Purpose The aim of this study was to investigate internal Achilles tendon (AT) displacement, AT shear wave velocity (SWV), and triceps surae (TS) muscle modulus in athletes. Methods Internal displacement assessed using ultrasound during isometric contraction. Shear elastography used assess SWV (m × s –1 ) at rest TS (kPa) passive ankle dorsiflexion. Results A total 131 athletes participated study. Athletes who had not exercised within two days greater non-uniformity mean anterior...
Enhancing traditional three-dimensional gait analysis with a portable ultrasound device at the lower-limb muscle-tendon level enables direct measurement of muscle and tendon lengths during walking. However, it is important to consider that size probe its attachment on lower limb may potentially influence pattern.
ABSTRACT Purpose To investigate early structural and mechanical predictors of plantarflexor muscle strength the magnitude Achilles tendon (AT) nonuniform displacement at 6 12 months after AT rupture. Methods Thirty‐five participants (28 males 7 females; mean ± SD age 41.7 11.1 years) were assessed for isometric plantarflexion maximal voluntary contraction (MVC) nonuniformity Structural properties measured 2 months. Limb asymmetry index (LSI) was calculated all variables. Multiple linear...
BackgroundTo better understand muscle remodelling in dynamic conditions after an Achilles tendon rupture, this study examined the length of medial gastrocnemius fascicles during a heel-rise at 6- and 12-months non-operative ATR treatment.MethodsParticipants (15 M, 3F) were diagnosed with acute rupture. Medial subtendon length, fascicle pennation angle assessed resting conditions, shortening bi- unilateral heel-rises.FindingsFascicle was smaller on injured side (mean difference [95% CI]: −9.7...
BackgroundThe interplay between the medial gastrocnemius muscle and Achilles tendon is crucial for efficient walking. In cerebral palsy, remodelling alters role of contractile elastic components. The aim was to investigate length changes belly fascicles, understand their gait propulsion in individuals with palsy.MethodsTwelve young palsy 12 typically developed peers were assessed during multiple cycles using 3D analysis combined a portable ultrasound device. By mapping image locations into...
The Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score (KJOC) is developed to evaluate the shoulder elbow function in overhead athletes. To date, has not been adapted into Finnish language. aim of this study was perform a cross-cultural adaptation language its validity, reliability, responsiveness athletes.Forward-backward translation method followed process. Subsequently, 114 athletes (52 males, 62 females, mean age 18.1 ± 2.8 years) completed version KJOC score, Disabilities Arm, Hand...
