Description: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disease with estimated prevalence of 1 in 5000 that characterized by the presence vascular malformations (VMs). These result chronic bleeding, acute hemorrhage, and complications from shunting through VMs. The goal Second International HHT Guidelines process was to develop evidence-based consensus guidelines for management prevention HHT-related symptoms complications. Methods: were developed using AGREE II...
Planar biaxial tension remains a critical loading modality for fibrous soft tissue and is widely used to characterize mechanical response, evaluate treatments, develop constitutive formulas, obtain material properties use in finite element studies. Although the application of on all edges test specimen represents situ environment, there need address interpretation experimental results. Unlike uniaxial tension, applied forces at clamps do not transmit fully region interest (ROI), which may...
The heterogeneous composition and mechanical properties of the supraspinatus tendon offer an opportunity for studying structure-function relationships fibrous musculoskeletal connective tissues. Previous uniaxial testing has demonstrated a correlation between collagen fiber angle distribution mechanics in response to tensile loading both parallel transverse longitudinal axis. However, planar may be more appropriately characterized through biaxial testing, which avoids limitation...
Semitendinosus/gracilis (STG) tendon autograft has been used effectively for restoring knee stability after anterior cruciate ligament (ACL) rupture. Though ACL reconstruction with STG is an effective surgical technique return to sports, short-term hamstring strength asymmetries exist surgery. Although imaging evidence demonstrated regrowth and reorganization of the semitendinosus (ST) tendon, no studies show whether associated residual muscle function. Continuous shear wave elastography...
Changes in tendon viscoelastic properties are observed after injuries and during healing as a product of altered composition structure. Continuous Shear Wave Elastography is new technique measuring soft tissues using external shear waves. Tendon has not been studied with this technique, therefore, the aims study were to establish range viscosity moduli healthy Achilles tendons, determine bilateral differences these parameters explore correlations viscoelasticity plantar flexion strength...
The mechanical behavior of the annulus fibrosus (AF) intervertebral disc can be modeled as a mixture fibers, extra-fibrillar matrix (EFM), ions, and fluid. However, properties EFM have not been measured directly. We human at several locations, determined effect age degeneration, evaluated whether changes in correspond to AF compositional changes. were using method that combines osmotic loading confined compression. samples dissected from correlated with age, composition. modulus was found...
Achilles tendinopathy is a debilitating overuse injury characterized by pain, altered tendon structure, and impaired functional performance. Evaluating structure as part of the physical examination may help establish well-defined prognosis. However, usefulness measuring for developing prognosis has been questioned since structural abnormalities can exist without symptoms.To determine whether initial measures morphology mechanical properties were associated with patient-reported symptoms calf...
Patellar tendons are assumed to be uniform in morphology and mechanical properties despite a higher prevalence of tendinopathies observed the medial region. The purpose this study was compare thickness, length, viscosity, shear modulus medial, central, lateral regions healthy patellar young males females vivo. B-mode ultrasound continuous wave elastography were performed on 35 (17 females, 18 males) over three interest. A linear mixed-effects model (α = 0.05) used determine differences...
Abstract Graft site morbidities after bone‐patellar tendon‐bone (BPTB) autograft harvest for anterior cruciate ligament reconstruction (ACLR) negatively impacts rehabilitation. The purpose of this study was to establish tendon structural properties 1‐month BPTB compared the uninvolved patellar tendon, and subsequently quantify healing trajectory over course Patellar morphology (ultrasound) mechanical (continuous shear wave elastography) from 3 regions (medial, lateral, central) were measured...
Purpose This study aims to: (1) measure the shear modulus of nucleus pulposus (NP) in intact human vertebra–disc–vertebra segments using a magnetic resonance elastography setup for 7T whole-body scanner, (2) quantify effect disc degeneration on NP measured elastography, and (3) compare to other resonance-based biomarkers dis degeneration. Methods Thirty were classified as normal, mild, or severely degenerated. The was custom-made that included novel inverse method less sensitive noisy...
Achilles tendinopathy negatively affects a person's ability to be physically active. However, remaining active during the rehabilitation process does not impact clinical outcomes when pain-monitoring model is followed. There are several factors, such as progression of pain and structural changes, kinesiophobia, functional impairments, or medical advice, which may explain why some patients become inactive while others maintain lifestyle.The purposes this study were 1) compare presentation...
Patellar tendon injuries occur via various mechanisms such as overuse, or due to surgical graft harvest for anterior cruciate ligament reconstruction (ACLR). Quantified patellar stiffness after injury may help guide clinical care. Continuous shear wave elastography (cSWE) allows the assessment of viscosity and modulus in tendons. The reliability measure, however, has not been established tendon. purpose this study was investigate interrater reliability, intrarater between-day stability cSWE...
