NCT07336407
This study conducted at three locations, aiming to collect ultrasound images from volunteers and assess the performance of an AI software, MSK Go, using these images. The software to be assessed is designed to assist physicians and healthcare professionals in performing ultrasound exams by classifying scan views and identifying key anatomical structures during a musculoskeletal ultrasound examination. The main question the study aims to answer is whether the AI software performs safely and effectively for future clinical use.

Point-of care-ultrasonography has the potential to transform healthcare delivery through its diagnostic and therapeutic utility. Its use has become more widespread across a variety of clinical settings as more investigations have demonstrated its impact on patient care. This includes the use of point-of-care ultrasound by trainees, who are now utilizing this technology as part of their diagnostic assessments of patients. However, there are few studies that examine how efficiently trainees can learn point-of-care ultrasound and which training methods are more effective. The primary objective of this study is to assess whether artificial intelligence systems improve internal medicine interns' knowledge and image interpretation skills with point-of-care ultrasound. Participants shall be randomized to receive personal access to handheld ultrasound devices to be used for learning with artificial intelligence vs devices with no artificial intelligence. The primary outcome will assess their interpretive ability with ultrasound images/videos. Secondary outcomes will include rates of device usage and performance on quizzes.
NCT06878911
This single-center, prospective study is being conducted at AABP Integrative Pain Care and Wellness in Brooklyn, New York, USA. The aim of this study is to collect ultrasound images from healthy volunteers and evaluate the performance of the Nerveblox software using this image dataset. Nerveblox is a software as a medical device which is designed to assist anesthesiologist for ultrasound-guided regional anesthesia, prior to needling procedure.
NCT05649826
This research examines echocardiography images taken from cardiac patients in relation to the guidance tool developed
NCT06219876
Carpal tunnel syndrome is the most common entrapment neuropathy and is frequently encountered in clinical practice. Although there is no standard protocol for its treatment, conservative treatment methods are preferred. In our study, we aimed to clinically compare the efficacy of high and low intensity laser treatments in patients with carpal tunnel syndrome. By using methods such as electromyography and ultrasound, we aimed to provide a more objective evaluation
NCT05455346
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.
NCT05872906
According to ancient literature, when de qi occurs in the process of acupuncture, the patient may experience sensations such as soreness, numbness, heaviness, swelling. Meanwhile, the acupuncturist may experience the sensation of "a fish taking a bite from the bait on a hook". However, for a beginner at acupuncture, before they have learned to trigger the de qi sensation, it is hard for them to learn according to the ambiguous definition of "a fish taking a bite from the bait on a hook" and thus hard to know whether they have reached the correct location and stimulated de-qi. In this study, through multiple experienced acupuncturists acupuncture multiple test subjects, the investigators will locate the location and the reaction of de qi on the acupoint Quchi (LI11) with ultrasound observation and recording. Through the ultrasound teaching and guidance, the investigators will test whether it is possible to reversely use ultrasound imaging to guide less experienced acupuncturists to the de qi location and elicit de qi response on multiple test subjects. Therefore, the investigators propose this study to test the following hypothesis:"There is a specific anatomical site where de qi occurs at LI11, and it is possible to use ultrasound imaging to guide learners to reach that location and trigger de-qi and that it is applicable to other acupoints". To explore the above hypothesis, the investigators will target the following specific aims. Aim 1: Use ultrasound record and indicate the precise anatomical location and reaction when de qi occurs on acupoint LI11. Aim 2: Simultaneously record the physicians' needling sensations, the participants' needling sensations, twitch response of the participant under ultrasound images. Aim 3: Prove the feasibility of using ultrasound to guide inexperienced physicians to reach the correct location and elicit de qi sensation on the participants. Aim 4: Discuss the relationship between de qi and pulse diagnosis. Aim 5: Apply the above procedures to other acupuncture points such as LU5(Chize), PC3 (Quze),…etc.
NCT04906018
This is a single-center, prospective study to be undertaken at University of Oregon, Portland, USA. The aim is to evaluate the clinical performance of ScanNav Anatomy PNB when highlighting anatomical structures during UGRA scanning. Specifically, we aim to assess and quantify the correct/incorrect highlighting of anatomical structures associated with ScanNav Anatomy PNB during UGRA scanning.
NCT04277169
This is a single-centre, prospective, non-randomised volunteer study to be undertaken in the MediCentre, Heath Park, Cardiff, UK
NCT03647618
This mutlicentre study at three hospitals in south Wales, UK, will be used to determine if modern machine learning techniques can help the anaesthetist locate the target by highlighting key anatomical features on the ultrasound image in real time. The study consists of two phases: The objective of Phase I is to train a computer-aided system to identify target structures in regional anaesthesia when applied in the following categories: * Adductor canal * Popliteal * Fascia Iliaca * Rectus sheath * Axillary The objective of Phase II is to estimate the success rate and safety of the computer system being developed.
NCT04511143
The goal of this study is to investigate potential relations of ultrasound-based muscle architecture parameters and isometric knee flexor muscle strength (IKFS) in healthy individuals. IKFS was measured for twenty participants (22.15±2.41 y.o; 8 females, 12 males) by a hand-held dynamometer. Investigated parameters were total and individual cross-sectional areas (CSA), Muscle-Thickness (MT), and pennation-angle (PA) for Biceps Femoris-long head (LBF), Semitendinosus (ST) and Semimembranosus (SM) muscles at 25%, 50% and 75% length of the thigh.
NCT02356601
Ultrasound is used increasingly to aid placement of neuraxial blocks. Good visibility of ligamentum duramater complex and posterior longitudinal ligament (LF, PLL) has a positive predictive value of 85% for successful neuraxial block. Dural puncture could still be feasible despite the absence of a good view, as reflected by a negative predictive value of 30%. Poor neuraxial ultrasound view could be due to limitations of ultrasound or various other anatomical reasons which might include absent LF, calcification of ligaments, spinous process contact and presence or absence of epidural or subdural fat. This will be the first study of its kind to compare neuraxial ultrasound with MRI. The aim of this study is to look for anatomical correlation between neuraxial ultrasound and MRI at various lumbar interspinous levels and to look at factors that contribute to abnormal neuraxial imaging. Assuming the predicted abnormal ultrasound images to be around 30% and predicted abnormal MRI images to be 5%, 79 images should give a power of 0.9 and alpha 0.01 to analyse the association between the two. Sample Size Calculations were performed using statistical software R version 2.15.2
