Artificial intelligence accurately predicts stroke risk
[Image from unsplash.com]Machine-learning algorithms, a form of artificial intelligence, accurately predicted people’s risk of heart disease and stroke, according to new research from the University of Nottingham.
Researchers and computer scientists compared the risk guidelines for heart disease and stroke from the American College of Cardiology with 4 machine-learning algorithms to analyze the risk of a patient having each. The results showed that the artificially intelligent algorithms were significantly more accurate at predicting cardiovascular disease than the regular medical models.

FDA clears software using AI to evaluate CT scans for stroke
Artificial Intelligence healthcare developer Viz.ai said this week it won approval from the FDA for its LVO Stroke platform designed to analyze computed tomography results and notify providers of potential strokes, touting it as the first such system to win FDA clearance.
The company’s LVO Stroke platform is designed using deep learning and connects to a hospital CT scanner to alert stroke specialists that a suspected LVO stroke has been identified, with the ability to send radiological images directly to the physician’s phones.
“Timely LVO stroke identification and transfer to a specialist hospital that ...

Stroke Rehab Technology Aims To Speed Healing
Watching someone who has suffered a stroke try to perform everyday actions such as walking down the sidewalk or even bringing a cup to their lips can serve as a sobering reminder of how fragile full and robust health is, and also serves as an inspiration for those dedicated to improving the lives of those patients.
Steven Plymale, recently named CEO of Toronto-based MyndTec, said his reaction to watching videos of patients using the company's MyndMove functional electrical stimulation (FES) rehabilitation system was one of the reasons he joined MyndTec.
"They are very compelling," Plymale said of the demonstration videos,Â...

Sequentially applied myoelectrically controlled FES in a task-oriented approach and robotic therapy for the recovery of upper limb in post-stroke patients: A randomized controlled pilot study.
CONCLUSIONS: Preliminary findings indicate that a combination of MeCFES and robotic treatment may be more effective than standard care for recovery of the plegic arm in persons > 3 months after stroke. The mix of motor learning techniques may be important for successful rehabilitation of arm function.

AI Becoming Prevalent in Identifying Stroke, Head Trauma
Another company is throwing its hat into the ring to use artificial intelligence to help identify bleeds, fractures and other critical abnormalities in head CT scans. San Mateo, CA-based Qure.ai released the results of a clinical validation study confirming its algorithm’s near-radiologist performance on 21, 000 patients and has made a dataset of almost 500 AI-analyzed head CT scans available for download.
The results have been published in a research paper on Cornell University's online distribution system for research, arXiv.org. The paper is titled “Development and Validation of Deep Learning Algorithms for Detectio...

AI-Based Stroke Rehab System Shown to Be as Effective as One-on-One Therapy
The idea that the brain is capable of rewiring after a stroke is not new, but the therapy needed to achieve this is cumbersome at best. “Studies show that neuroplasticity requires hundreds to thousands of hours of repetition of focused, concentrated training to get the brain to have those functional changes,†said David Wu, Motus Nova’s CEO, in an interview with MD+DI. But he explained that those many hours of therapy with a clinician are not always feasible for patients, because of concerns about time and logistics, cost, and sometimes even a lack of motivation.
So, Mo...

MassDevice Q & A: Claret Medical ’ s Azin Parhizgar on trying to make TAVR safer
Cerebral protection developer Claret Medical recently won FDA de novo clearance for its Sentinel device designed to trap blood clots and prevent stroke during heart valve replacement procedures.
The Sentinel uses a pair of filters, 1 in the brachiocephalic artery another in the left common carotid artery, to trap debris released during transcatheter aortic valve replacement that could cause a cerebral embolism.
The device has seen a rough road to approval, however, after missing the primary efficacy endpoint in its pivotal trial. Despite that, the device saw nearly unanimous support from an FDA advisory panel and was c...

Forest Devices Is Crushing It This Year
Forest Devices added another feather to its cap at The MedTech Conference in Boston, MA where the startup won the MedTech Innovator 2019 Showcase and received a $350,000 grand prize award.
Forest is developing AlphaStroke, the first device designed to detect a stroke in any environment. The portable device uses electroencephalogram monitoring and machine learning to diagnose large vessel occlusions and other stroke subtypes, enabling first responders to triage patients to proper stroke centers. In 2018, the Pittsburgh, PA-based company closed an oversubscribed see...

Biotronik launches trial of CLS AF algorithm
Biotronik said today it enrolled the 1st patient in its B3 trial examining the company’s Closed Loop Stimulation physiologic rate response sensor and algorithm.
The study aims to whether pacemakers and implantable cardioverter-defibrillators equipped with the CLS sensor and algorithm are able to reduce the rate of stroke and improve outcomes in patients with atrial fibrillation compared to those without the system.
“AF is a huge clinical challenge, affecting over 20 million patients in Europe and the US alone. I am very excited to begin this groundbreaking trial. We hope to demonstrate that the physiological h...

Is FDA Getting More Cozy with AI?
The use of artificial intelligence (AI) is undoubtedly on the rise in healthcare. From fledging medtech companies to established giants like Watson IBM—many firms are riding the current AI wave. Not only are companies embracing technology, but so is FDA.
Recently the agency gave approval to San Francisco-based Viz.ai’s Contact application, a type of clinical decision support software designed to analyze CT results that could notify providers of a potential stroke in their patients. “What it’s doing is comparing the imaging features in that patient with the millions of images it has been trained on in the past, in...

Learning to Walk Again
When someone suffers a stroke, he or she often loses some mobility, and some 60 percent of survivors are left with lower-limb deficits. “They usually have one leg that's more impaired than the other leg, and then they undergo rehabilitation and physical therapy. And often they don't fully recover,†said Conor Walsh, professor of engineering and applied sciences at the John A. Paulson Harvard School of Engineering and Applied Sciences and a core faculty member at the Wyss Institute for Biologically Inspired Engineering, in an interview with MD+DI.
But a new device called ReSto...
