Filter by:The application of pulsed negative pressure to the scar tissue stimulates the cellular response, producing elastic changes in the tissue, quantifiable by ultrasound, not only in terms of thickness but also in the elastic capacity of the tissues, measured by quantified elastography.
The aim of thid study was to compare two methods applied to increase the flexibility of the hamstring muscles and objectively evaluate changes in muscle stiffness using the two-dimensional shear wave ultrasound elastography (2D SWE) method. Thirty asymptomatic young individuals with hamstring shortness were divided into two groups by simple randomization. The Mulligan bent leg raise (BLR) technique was applied to the first group, and passive static stretching exercises to the second group. Hamstring flexibility was evaluated with the sit-and-reach test, and muscle stiffness with the 2D SWE method.
To determine accuracy of elastography in assessment of superficial lymph nodes response to treatment in cases of lymphoma.
In our study, we aimed to examine the muscles and tendons of the shoulder region on the plegic side of patients with hemiplegia by elastography and to investigate whether there is a relationship between the course of the disease and the course of the lesions that will occur in the shoulder.
The overall goal of this study is to investigate the effects of a 6-week training program between two hamstring exercises-the Romanian deadlift (RDL) and the Nordic hamstring exercise (NHE)-on hamstring strain injury risk factors and sprint performance.
In this prospective cohort study, the patients who were diagnosed with either uterine fibroid (control group) or adenomyosis (study group), were examined with transvaginal ultrasound and shear wave elastography. Definitive diagnosis was established by pelvic MRI. Shear wave elastography data of both groups were compared. Features of adenomyosis on transvaginal ultrasound were also recorded for study group.
Before any treatment decisions are made for patients with lung cancer, it is crucial to determine whether the cancer has spread to the lymph nodes in the chest. Traditionally, this is determined by taking biopsy samples from these lymph nodes, using the Endobronchial Ultrasound Transbronchial Needle Aspiration (EBUS-TBNA) procedure. Unfortunately, in 40% of the time, the results of EBUS-TBNA are not informative and wrong treatment decisions are made. There is, therefore, a recognized need for a better way to determine whether the cancer has spread to the lymph nodes in the chest. The investigators believe that elastography, a recently discovered imaging technology, can fulfill this need. In this study, the investigators are proposing to determine whether elastography can diagnose cancer in the lymph nodes. Elastography determines the tissue stiffness in the different parts of the lymph node and generates a colour map, where the stiffest part of the lymph node appears blue, and the softest part appears red. It has been proposed that if a lymph node is predominantly blue, then it contains cancer, and if it is predominantly red, then it is benign. To study this, the investigators have designed an experiment where the lymph nodes are imaged by EBUS-Elastography, and the images are subsequently analyzed by a computer algorithm using Artificial Intelligence. The algorithm will be trained to read the images first, and then predict whether these images show cancer in the lymph node. To evaluate the success of the algorithm, the investigators will compare its predictions to the pathology results from the lymph node biopsies or surgical specimens.
Little is known about the correlation between ultrasound characteristics (conventional, elastography and contrast enhanced ultrasound (CEUS) )and pathological prognostic factors in breast cancer. The aim of this study was to explore the correlation between ultrasound characteristics and pathological prognostic factors using radiomics.
Chronic kidney disease is a common global public health issue and its prevalence increased year by year. Early diagnosis and intervention can prevent further complications and comorbidities of long-term dialysis, cardiovascular events and mortality as well as improve the patients' life quality. To differentiate acute from chronic kidney disease was crucial especially in the setting of crowded and high-risk emergency department. To diagnose acute or chronic kidney disease, physicians usually use blood sample test combined with image studies such as conventional sonography, CT and MRI. However, there was lots of limited factors. The patients may have no previous visit records, poor renal function to receive contrast medium, or critical clinical condition to undergo time-wasting exam. Although the conventional renal sonography is accessible and inexpensive, the judgement is subjective and provide little clinical information. Recent researches of shear wave elastography in evaluating renal parenchymal stiffness showed some correlation with nephropathy. In our study, aiming to facilitating clinical implication, the investigators will use swear-wave elastography combined with conventional renal sonography to benefit patients in diagnosis of acute or chronic kidney disease.
Football is an increasingly popular exercise and common practice among adolescent and elite athletes. However, these athletes tend to have injuries involving the lower extremity and foot. Recent literature has proposed a promising concept of core stability on the arch of the foot and proximal hip control exercise for a knee injury. They have highlighted that foot core training begins with targeting the plantar intrinsic muscles through exercise intervention, which may enhance the capacity and control of the foot core system. Moreover, it is hypothesized that the 'complexity algorithm' of exercise intervention for proximal hip control may provide more sufficient effects on musculoskeletal pain in the lower extremity. However, some conflicting issues such as assessment and training of foot intrinsic muscle in functional positions still largely lack devices and research to elucidate the underlying mechanism of its development and integrated exercise interventions proximally and distally on these athletes. Firstly, the investigators aim to design and develop of novel intrinsic foot muscle assessment and training device for sporting tasks and to examine the feasibility and reliability of muscle stiffness in foot and hip joints before and after exercise intervention using shear wave ultrasound elastography (SWUE) in athletes without and with foot and ankle overuse injuries; second, investigators will investigate whether immediate and persistent alteration after the integrated therapeutic exercise on motor control and muscle stiffness.
