Freehand three-dimensional ultrasound (3DUS) was used to investigate longitudinal and biaxial transverse deformation rotation of the free Achilles tendon in vivo during a voluntary submaximal isometric muscle contraction. Participants ( n = 8) were scanned at rest 70% maximal contraction (MVIC) plantarflexors. Ultrasound images manually digitized render 3D reconstruction for computation length, volume, cross-sectional area (CSA), mediolateral diameter (MLD), anteroposterior (APD), rotation....
Mechanical loading of the Achilles tendon during isolated eccentric contractions could induce immediate and region-dependent changes in mechanical properties. Three-dimensional ultrasound was used to examine effect exercise on properties distal (free tendon) proximal (gastrocnemii) regions tendon. Participants (n = 14) underwent two testing sessions which measurements were made at rest a 30% 70% isometric plantar flexion immediately before after either: (a) 3 × 15 heel drops or (b) 10-min...
Musculoskeletal tissues, including tendon, are sensitive to their mechanical environment, with both excessive and insufficient loading resulting in reduced tissue strength. Tendons appear be particularly strain magnitude, there appears an optimal range of tendon that results the greatest positive adaptation. At present, no tools allow localized rapidly measured or estimated training a clinical environment. In this paper, we first review current literature regarding Achilles adaptation,...
Our work combines medical imaging and electromyogram-informed neuromusculoskeletal modeling data to estimate free Achilles tendon strain during selected rehabilitation, locomotor, jumping, landing tasks in trained middle-distance runners. These may potentially be used inform training rehabilitation maximize anabolic remodeling.
Our understanding of in vivo Achilles tendon (AT) conditioning is limited to two-dimensional ultrasound measures longitudinal deformation the whole tendon. This study investigated regional three-dimensional (3D) AT during conditioning. Eighteen ATs were scanned using 3D freehand 10 successive 25 s submaximal (50%) voluntary isometric plantarflexion contractions. Longitudinal strain was assessed for AT, aponeurosis, and free transverse proximal-, mid-, distal-portions AT. primarily driven by...
Mid-portion Achilles tendinopathy (MAT) alters the normal three-dimensional (3D) morphology of tendon (AT) at rest and under a single tensile load. However, how MAT changes 3D AT during repeated loading remains unclear. This study compared longitudinal, transverse volume strains in with those contralateral people unilateral MAT. Ten adults performed 10 successive 25 second submaximal (50%) voluntary isometric plantarflexion contractions both legs. Freehand ultrasound scans were recorded used...
Cerebral palsy (CP) remains the world's most common childhood physical disability with total annual costs of care and lost well-being $A3.87b. The PREDICT-CP (NHMRC 1077257 Partnership Project: Comprehensive surveillance to PREDICT outcomes for school age children CP) study will investigate influence brain structure, body composition, dietary intake, oropharyngeal function, habitual activity, musculoskeletal development (hip status, bone health) muscle performance on motor attainment,...
Our understanding of the immediate effects exercise on Achilles free tendon transverse morphology is limited to single site measurements acquired at rest using 2D ultrasound. The purpose this study was provide a detailed 3D description changes in immediately following clinical dose exercise. Freehand ultrasound used measure length, and regional cross-sectional area (CSA), medio-lateral (ML) diameter antero-posterior (AP) healthy young adults (n=14) during isometric muscle contraction, before...
Tendon geometry and tissue properties are important determinants of tendon function injury risk altered in response to ageing, disease, physical activity levels. The purpose this study was compare free Achilles mechanical between trained elite/sub-elite middle-distance runners a healthy control group. Magnetic resonance imaging (MRI) used measure volume, length, average cross-sectional area (CSA), regional CSA, moment arm, T2* relaxation time at rest, while freehand three-dimensional...
This study investigated reliability of freehand three-dimensional ultrasound (3DUS) measurement in vivo human Achilles tendon (AT) moment arm. Sixteen healthy adults were scanned on 2 separate occasions by a single investigator. 3DUS scans performed over the free AT, medial malleolus, and lateral malleolus with ankle passively positioned maximal dorsiflexion, mid neutral, plantar flexion flexion. 3D reconstructions created from manual segmentation images used to geometrically determine AT...
