Lateropulsion, a clinical condition which results in the body leaning to one side, affects about half of all stroke survivors.
Edith Cowan University (ECU) PhD graduate Dr Jessica Nolan said while the problem is common, lateropulsion is still severely under recognised and under assessed around the world.
“A person with lateropulsion uses the limbs on their stronger side, to push themselves over toward their weaker side. Often those with lateropulsion resist correction back towards their stronger side or the mid-line, and this can cause problems with sitting, standing, walking and looking after themselves. It is also associated with a higher risk of falling, reduced recovery and a reduced likelihood of discharge after in-patient rehabilitation,” Dr Nolan said.
“The treatment of lateropulsion in stroke survivors is a critical aspect of rehabilitation, however the issue requires better understanding and more research.”
It is estimated that in 2020, there were some 39 500 stroke events in Australia, averaging more than 100 a day. In that same year, it was estimated that more than 445 087 Australians were living with the side effects of stroke. Stroke is one of Australia’s biggest killers, with the event killing more women than breast cancer and more men than prostate cancer.
Despite the prevalence of lateropulsion following a stroke event, a lack of agreement on terminology and the defining features of the condition present obstacles to understanding its prevalence, accurately comparing research results, and agreeing on a consistent approach to rehabilitation.
“People affected after a stroke may be at a disadvantage, because of the inconsistent approaches to rehabilitation and the failure of health policy to accommodate their rehabilitation needs,” Dr Nolan said.
“Improved understanding of the condition could lead to improved management, which will enhance patient outcomes after stroke and increase efficiency of healthcare resource use.”
Dr Nolan has previously led a Delphi consensus process, partnering with 21 international experts to reach a consensus on the terminology used to describe the condition and on the rehabilitation requirements for people living with severe lateropulsion, as well as recommendations for rehabilitation.
While a consensus regarding terminology was not reached, the panel achieved some agreement that lateropulsion was the preferred term to describe the phenomenon. More than 100 consensus-based recommendations were also provided to guide rehabilitation of lateropulsion.
In her latest research, Dr Nolan found that lateropulsion could continue to resolve up to one-year post-stroke, far beyond the period of in-patient rehabilitation. Average in-patient length of stay following a stroke varies, but for those patients presenting with lateropulsion, in-patient stay was about three to four weeks longer compared to those without.
“This study was the first to investigate functional recovery up to 12 months post-stroke, and to compare outcomes among people with and without lateropulsion. This study supports findings from previous work that lateropulsion severity was a predictor of long-term functional outcomes.”
“Lateropulsion after stroke can resolve, but it is dependent on access to ongoing rehabilitation.
“People who do not have access to long-term rehabilitation following a stroke did not show the same extent of lateropulsion resolution or functional recovery.”

Reinforcement learning (RL) is a machine learning technique that trains software by mimicking the trial-and-error learning process of humans. It has demonstrated considerable success in many areas that involve sequential decision-making. However, training RL models with real-world online tests is often undesirable as it can be risky, time-consuming and, importantly, unethical. Thus, using offline datasets that are naturally collected through past operations is becoming increasingly popular for training and evaluating RL and bandit ...
Researchers at the University of Arizona College of Medicine – Tucson were awarded a $1.8 million grant by the National Institute of General Medical Sciences, a division of the National Institutes of Health, to learn how human papillomavirus makes its way to a cell’s nucleus.
Human papillomavirus, or HPV, which can cause warts and certain cancers, has been with us since the dawn of humanity and causes about 5% of cancers worldwide. It also is an important source of information about human biology, according to Samuel K. Campos, PhD, an associate professor of immunobiology at the University of Arizona College of Medicine ...
A new study has found there are no adverse long-term cardiovascular health consequences for the now-adult children of mothers who were given corticosteroids because they were at risk of early birth in a landmark trial conducted in Auckland, New Zealand, 50 years ago.
The Auckland Steroid Study by obstetrician Professor Graham ‘Mont’ Liggins and paediatrician colleague Dr Ross Howie from 1969 to 1974 in Green Lane Hospital, Auckland, found that two corticosteroid injections given to pregnant women at risk of early (preterm) birth halved the incidence of respiratory distress in the babies and significantly reduced neonatal deaths.
Co-author of the new study, Dr ...
Active military service may heighten a woman’s risk of having a low birthweight baby, suggests a review of the available scientific evidence published online in the journal BMJ Military Health.
The findings highlight the need for more research specifically focused on women in the armed forces, and their reproductive health in particular, conclude the study authors.
Worldwide, increasing numbers of women are on active service in their country’s armed forces. The UK Armed Forces, for example, has set a target of 30% female representation by 2030. And more and more countries are deploying women in combat ...
National clinical guidelines for the treatment of COVID-19 vary significantly around the world, with under-resourced countries the most likely to diverge from gold standard (World Health Organization; WHO) treatment recommendations, finds a comparative analysis published in the open access journal BMJ Global Health.
And nearly every national guideline recommends at least one treatment proven not to work, the analysis shows.
Significant variations in national COVID-19 treatment recommendations have been suspected since the advent of the pandemic, but these haven’t been ...
Health concerns are still the primary motive for more than half of those who say they want to stop smoking in England, but cost is now a key factor for more than 1 in 4, finds an analysis of national survey responses, published in the open access journal BMJ Public Health.
Given this shift in thinking, making much more of the potential savings to be had might encourage more people to stub out for good, suggest the researchers.
Health concerns are generally the primary motive for people trying to stop smoking, with social and ...
Anti-N-methyl-d-aspartate (Anti-NMDA) receptor encephalitis is an acute
autoimmune disorder that develops both neurological symptoms and psychiatric
symptoms, including hallucination, cognitive disturbance, epilepsy, movement
disorder, and impaired consciousness. This disease may be misdiagnosed at the early
stage as a psychosis disease because of primary psychiatric symptoms. The
misdiagnosis may delay appropriate therapeutic intervention. Most patients with
anti-NMDA receptor encephalitis respond to immunotherapy [1, 2].
The pathology of this disease is ...

Working memory is one of the brain’s executive functions, a skill that allows humans to process information without losing track of what they’re doing.
In the short term, working memory allows the brain to complete an immediate task, like loading the dishwasher. Long term, it helps the brain decide what to store for future use, such as whether more dishwasher soap will be needed.
University of Texas at Arlington researchers know that working memory varies greatly among individuals, but they aren’t sure exactly why. To better understand, Matthew Robison, assistant professor of psychology, and doctoral student Lauren D. Garner conducted an experiment to see if ...
