Could online programming reduce barriers for those with mobility impairments?
LONDON, ON – A new study at Lawson Health Research Institute will offer online exercise and behavioral intervention for adults who are mobility impaired. The goal is to reduce barriers to accessing activity programs.
“Many people with mobility concerns experience barriers to physical activity, such as fear of falling because of their past injuries,” says Dr. Swati Mehta, Lawson Scientist. “This project aims to help them cope and learn skills to continually, actively engage in physical activity.”
The 10-week virtual program is being coordinated through St. Joseph’s Health Care London’s Parkwood Institute. It will consist of weekly personal behavioral coaching. Participants will also be asked to complete two or three group physical activity programs each week, such as seated aerobics, seated boxercise and seated yoga.
“This study is really exciting because it brings together both behavioral coaching and physical activity classes, which are normally offered separately,” explains Dr. Dalton Wolfe, Lawson Scientist. “This provides extra support to help those with mobility impairments overcome barriers to maintaining an active lifestyle.”
Those barriers can include things like fatigue and transportation challenges that often accompany neurological conditions like multiple sclerosis, spinal cord injury, brain injury and stroke.
“Ultimately this study is about enhancing quality of life and wellbeing while improving participants’ ability to engage in the community,” says Dr. Wolfe.
The research team is currently recruiting 20 participants for the study. For more information on the study you can email @email.
COVID-19 shown to leave unique lung fingerprint
LONDON, ON – Researchers at Lawson Health Research Institute (Lawson) developed and tested an artificial neural network for diagnosing COVID-19. The AI system was trained to learn and recognize patterns in ultrasound lung scans of patients with confirmed COVID-19 infection at London Health Sciences Centre (LHSC) and compared them to ultrasound scans of patients with other types of lung diseases and infections.
“The AI tool that we developed can detect patterns that humans cannot. Lung ultrasound scans of patients with COVID-19, as well as other lung diseases, produce a highly abnormal imaging pattern, but it is almost impossible for a physician to tell apart different types of infections by looking at these images. There are details, however, that distinguish COVID-19 at the pixel level that cannot be perceived by the human eye,” explains Dr. Robert Arntfield, Lawson Researcher and Medical Director of the Critical Care Trauma Centre at LHSC.
“The neural network was able to identify the unique characteristics among different scans, and exceed human-level diagnostic specificity. Our study of over 100,000 ultrasound images showed that while trained physicians could – as expected - not distinguish between different causes of lung disease, the AI had nearly perfect accuracy in making the diagnosis. It’s almost like the AI sees a QR code that we cannot see, unique to the disease.”
LHSC is a global leader in the use of point-of-care ultrasound. It has become an important tool for the diagnosis and care of critically ill patients experiencing acute respiratory failure. The convenience, portability and low cost of using these machines makes them ideally suited for pandemic conditions.
This study is part of a collaborative effort by a small group of local clinicians driven to innovate and create technology that solves complicated problems with AI. “There are a lot of brilliant minds in our city, and I’m very proud that we were able to rapidly pull together a local team to design, develop and test a complex idea,” says Dr. Arntfield. “We are already expanding on these findings with more research.” Lawson has recently approved Dr. Arntfield’s “Project Deep Breathe” which aims to go beyond COVID-19 and explore multiple conditions where lung ultrasound and AI can be paired together.
The study, “Development of a convolutional neural network to differentiate among the etiology of similar appearing pathological B lines on lung ultrasound: a deep learning study”, is published in BMJ Open.

Cultivating ‘eureka’ moments
Discovery should be ‘everyone, everywhere,’ says Lawson Research Institute Scientific Director Lisa Porter.
Lisa Porter believes excellence in health research is a continuum of inquiry, inspiration, innovation and improved patient care.
That’s why she is so energized by the promise and potential of Lawson Research Institute (Lawson) at St. Joseph’s Health Care London (St. Joseph’s), where she is Scientific Director and Vice President Research.
“Discovery comes from exploring great questions. You can’t have a ‘eureka’ moment without asking why things work, or don’t work – and that’s what we do so well here at St. Joseph’s,” says Porter.
A distinguished scientist herself with a passion for asking those probing questions, Porter leads strategic planning for research across the organization. Her vision includes growing the rich culture of research in several specialty pillars, while also reinforcing direct links between scientific inquiry and patient health.
“There’s data to show that patients who are treated in research-intensive hospitals live longer. That’s not just patients in clinical trials who benefit; that’s all patients who live longer,” she notes.
Other elements of her vision for Lawson include elevating data sharing and research support, expanding training opportunities for young researchers, growing grant support, strengthening collaboration and partnerships, and building relationships and reputation.
“I love that excellence is one of the values of St. Joseph’s. Excellence doesn’t mean we have all the answers. It means we’re continuously striving to be better. It means we’re asking questions that can drive better health care – not just for the patients we serve, but for national and global impact, too.”
Porter comes from a family of knowledge-seekers and problem-solvers. Her father repaired electronics and was an avid inventor. Her mother was a self-taught income –tax preparer with meticulous attention to detail. They ignited in her a curiosity that continued through her undergraduate studies in biology and pharmacology, her graduate and postdoctoral work, and her research as a cancer scientist at University of Windsor and founding director of its WE-SPARK Health Research Institute.
Now at Lawson, she wants to encourage, inspire and spotlight the innovative work of researchers, scientists, clinicians and students who are passionate about improving health.
“I want research to be everyone, everywhere,” she says. “We need hospitals, industry, people with lived experience, and policy makers coming into the fray. It can’t be just the researcher, the scientist. It’s about having champions embedded in all walks of life, from first line of care to people who can influence systemic change. It’s a messy piece, but it’s also how we fulfil this bigger mission to help everyone who comes to us for health care.”
