Filter by:Quadriceps femoris (QF) atrophy is seen in rheumatoid arthritis and knee osteoarthritis (OA) patients. Exercise therapy is mile stone in knee OA patients also it can help thicken QF muscle of RA patients. We primarily aimed to demonstrate the influence of 4 weeks of knee isometric home-based training on QF muscle parts thickness and pennation angle measurements of RA patients with ultrasonography (USG). This study included 12 patients with RA, 12 patients with knee OA as positive control group and 13 volunteers as healthy control group. All participants were given 4 weeks of quadriceps-hamstring isometric home-based training. At baseline and at the end of the program, WOMAC and Lequesne algofunctional index scores of knee OA patients and DAS28-CRP scores of RA patients were recorded. Dominant knee thickness and pennation angle measurements of QF muscle parts were evaluated by ultrasonography.
Obesity is an important public health problem all over the world, and its prevalence is increasing every year. In obesity, significant changes occur in the mechanical properties of the lungs and chest wall due to fat deposits in the mediastinum and abdominal cavities. Upper abdominal surgical procedures usually cause impairment of respiratory functions by affecting respiratory volume and capacity. The risk of postoperative pulmonary complications increases with the decrease in restrictive capacities, hypoxemia, and increased respiratory work. It may also be due to causes such as diaphragm dysfunction, postoperative pain, and surgical incision.Ultrasonography (USG) is a method accepted for evaluating the normal and pathological conditions of the diaphragm. M-mode is used to evaluate the anatomical and functional disorders of the diaphragm. The diaphragm evaluation is performed with the anterior approach in the supine position and with different respiratory maneuvers (sniffing, deep inspiration, normal inspiration). The aim of the study was to evaluate the diaphragm function by using USG and spirometry methods in patients who underwent bariatric surgery and to investigate the effect of postoperative pain score on diaphragm function.
Context: Thoracic spine is a common area of focus in osteopathic manipulative medicine (OMM) for a variety of conditions. Thoracic spine somatic dysfunction diagnosis is achieved by palpating for asymmetry at the tips of the transverse processes. Previous studies reveal that, instead of following the rule of threes, the transverse processes of a given thoracic vertebra generally align with the spinous process of the vertebra above. Ultrasonography has been widely used as a diagnostic tool to monitor musculoskeletal conditions. Ultrasound has the advantage of absence of radiation, and has shown comparable results to gold standard modalities like MRI in some areas of the spine. In the case of thoracic somatic dysfunction, ultrasound can be used to determine the location of each vertebral transverse process and its relationship with the spinous process. Previous studies have investigated the correlation between osteopathic manipulative medicine and ultrasonography of the cervical, lumbar, and sacral regions. However, no study has yet compared osteopathic structural examination with ultrasonographic examination of the thoracic vertebral region. Objective: To determine whether there is a dependable correlation of osteopathic palpatory findings of the thoracic transverse processes with the measurements of ultrasonography. Methods: Subjects were student volunteers recruited from the Midwestern University - Glendale campus. A non-toxic, non-permanent marker was used to mark bony landmarks on the skin to be used by the osteopathic examiners. Two osteopathic physicians (OMM1, OMM2) separately performed structural exams by palpating T2-T5 transverse processes to determine vertebral rotation. Two trained sonographers (US1, US2) separately scanned and measured the distance from the tip of the spinous process to the adjacent transverse processes of the vertebral segment below. Demographic variables were summarized with mean and standard deviation. Interexaminer reliability was assessed with percent agreement, Cohen's Kappa, and Fleiss' Kappa. Recruitment and protocols were approved by the MWU Institutional Review Board.
Determination of fetal head position during labour is highly subjective and depends on clinician's experience in vaginal digital examination. Monitoring the progress of labour with intrapartum ultrasound (IU) exhibits higher accuracy rates. However, the dynamic process of labour needs very frequent sonographic examination and that may decrease the feasibility. Consultation to IU at certain time points can positively limit the need for ultrasound, increase the effectiveness of IU and allow for safer labour in consistency with traditional labour management. This study aims to investigate the use of IU in cases with suspected and diagnosed labour arrest in both the first and second stage of labour.
The carpal tunnel syndrome (CTS) is a common entrapment neuropathy caused by compression of the median nerve at the wrist.Clinically electroneuphysiological assessment is not accessible to all clinicians. In this way ultrasounds (US) is a more accessible and economical tool and many studies have reported that US has high sensitivity and specificity in the diagnosis of CTS.Diacutaneous Fibrolysis (DF) is a physiotherapeutic technique derived from Cyriax deep friction massage principles.DF technique could assist in improving changes in the connective tissues adjacent to the median nerve, especially the thickness of TCL and this could be reflected in a decreasing of TCL. Moreover, the neurophysiological and mechanical effect described by this technique may improve the nerve compression decreasing the CSA of the median nerve. The purpose of this study is to quantify changes in the cross-sectional area of the median nerve in the carpal tunnel and the thickness of transversal carpal ligament measured by US and the changes in the intensity of the numbness and the subjective assessment of clinical change after DF treatment in forearm, wrist and hand area compared to placebo.
This is a prospective cohort study that describes focused lung ultrasound (FLUS) findings in patients presenting with symptoms of an acute lower respiratory tract infection (LRTI) in general practice in Denmark. Ten general practitioners (GPs) will perform FLUS in addition to their usual care of adults presenting with symptoms of an acute LRTI where the GP suspects a community-acquired pneumonia (CAP). Eligible patients will consecutively be invited to participate during a two months' study period until each GP has included a total of ten patients. The GPs will register information about patients including age, gender, symptoms, clinical findings, results of any point-of-care test performed, if antibiotic treatment was prescribed and they will register information on FLUS performance and findings.
A major barrier to ultrasonography in general practice (GP) is the time restriction of their medical consultation. We aimed to evaluate the feasibility of lung ultrasonography (LUS) realized by general practitioners (GP's) into their medical consultation. A prospective, observational, multi-centric and open study conducted in 3 different centers by 15 GP in France. Patient receiving LUS were recruited from December 2019 to January 2020. GP's were all novices and received a training course by LUS expert before the study. Eight-points LUS exam was recorded, timed, and interpreted by GP's. Among the 111 LUS performed, 110 LUS were interpreted. Time duration was 4 (3-5) min with 13% of LUS superior to 5 minutes. There was no significant difference in time duration after stratification by age. Patients were mainly satisfied after receiving LUS, and 80% of patients had a better understanding about their disease due to US realization. In this first prospective, and multicenter study, involving patients consulting in General Practice, we found that LUS seems to be feasible by GP's in a medical consultation. We showed that LUS can be performed fast enough for a GP consultation, and easy to learn. These findings will need to be valided in a randomized and controlled study.
Objective: To determine the effectiveness of bilateral and simultaneous diaphragm visual biofeedback reeducation by ultrasonography in conjunction with high-intensity inspiratory muscle training versus isolated high-intensity inspiratory muscle training in patients with low back pain. Methods: A single blinded randomized clinical trial will be carried out. A total sample of 96 patients with low back pain will be recruited and randomized into 2 groups: one group will be treated by isolated high-intensity inspiratory muscle training during 8 weeks, and another group will be treated with bilateral and simultaneous diaphragm visual biofeedback reeducation by ultrasonography during 6 weeks in conjunction with high-intensity inspiratory muscle training during 8 weeks. Outcome measurements will be diaphragm muscle thickness evaluated by ultrasonography (main outcome measurement), pain intensity, pressure pain threshold, disability, quality of life and respiratory parameters by spirometry, which will be assessed before and after intervention.
Objectives: Although cone‐beam computed tomography (CBCT) is becoming a standard of care in implant therapy, concerns have been raised recently about its limitation in imaging peri-implant tissues due to artifacts. The aim of present study was to demonstrate the complementary role of ultrasound (US), for a comprehensive examination of peri-implant tissues in live humans. Material and Methods: Patients with > 1 implant, a CBCT scan, an US scan, and clinical photographs taken during the open-bone surgery were included. The crestal bone thickness (CBT) and facial bone level (FBL) were measured on both modalities, and direct FBL measurements were also made on clinical images. The correlation plots were made to evaluate the measurement agreements between the 3 methods.
A successful implant surgery primarily relies on a prudent evaluation of oral anatomy and meticulous treatment planning. Additionally, of paramount importance that dictates the types of procedures, material selection and ultimately success of implant surgery is the quality and quantity of the edentulous ridge. Ultrasound imaging (US), another cross-sectional imaging modality, has been extensively used in the medical diagnostics field. The ability of ultrasound to image soft tissue-bone interface makes it particularly promising for studying bone ridge width and crestal bone topography. Therefore, this retrospective human study aimed to compare bone width measurements between US and CBCT. This study also investigated the possible correlation between the crestal bone surface quality imaged by US and CBCT.
