Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Stroke is one of the leading causes for disability worldwide. Motor function deficits due to stroke affect the patients’ mobility, their limitation in daily life activities, their participation in society and their odds of returning to professional activities. All of these factors contribute to a low overall quality of life. Rehabilitation training is the most effective way to reduce motor impairments in stroke patients. This multiple systematic review focuses both on standard treatment methods and on innovating rehabilitation techniques used to promote upper extremity motor function in stroke patients. A total number of 5712 publications on stroke rehabilitation was systematically reviewed for relevance and quality with regards to upper extremity motor outcome. This procedure yielded 270 publications corresponding to the inclusion criteria of the systematic review. Recent technology-based interventions in stroke rehabilitation including non-invasive brain stimulation, robot-assisted training, and virtual reality immersion are addressed. Finally, a decisional tree based on evidence from the literature and characteristics of stroke patients is proposed. At present, the stroke rehabilitation field faces the challenge to tailor evidence-based treatment strategies to the needs of the individual stroke patient. Interventions can be combined in order to achieve the maximal motor function recovery for each patient. Though the efficacy of some interventions may be under debate, motor skill learning, and some new technological approaches give promising outcome prognosis in stroke motor rehabilitation.(I see NO PROGRESS  in stroke rehab, so I have no clue what the fuck you're looking at!)

What's overweight enough for lower disability after stroke?

 

My doctor did nothing to get me 100% recovered so I could stay active. Also didn't inform me that after age 50 my metabolism slows down and I should cut back on calories, gained 40 extra pounds, still have ways to go to get to a good weight.

Now at 28.4 BMI and not concerned at all.

FULL STORY

Slightly overweight stroke survivors have a lower risk of sustaining disabilities. The Kobe University finding adds another aspect to the obesity paradox but also highlights the importance of considering the population's normal when recommending best practices.

The obesity paradox is the well documented observation that amongst people who suffered a stroke, those who are moderately overweight have lower rates of mortality, recurrence and readmission compared to patients of "normal" weight. Recently, survival rates have improved and attention has shifted to the subsequent lives of the patients. The Kobe University health scientist IZAWA Kazuhiro says: "In my clinical practice I have experienced that patients with a thin physique often have difficulties in recovering function whereas relatively overweight people usually fare better. This motivated me to study whether there is a demonstrable relationship between body size and functional disability after a stroke."

Using a Japanese national database containing anonymized data on diagnosis-procedure combinations for all vascular and cardiac disease cases in hospitals across Japan, Izawa, postdoctoral researcher KANEJIMA Yuji and their team evaluated the size of different factors on over half a million patients' disability at the time of discharge from hospital. The factors they looked at were the body mass index (BMI), which is a person's weight relative to their height, the patients' age, gender, their disability score at the time of hospitalization, and others.

In the journal Topics in Stroke Rehabilitation, the Kobe University team now published their results. They found that, indeed, the risk of being discharged from hospital with a poor disability score was observed to be relatively low in people with a BMI between 22.1 and 27.5 kg/m2, and was lowest at a BMI of 24.7 kg/m2. Given that the WHO classifies Asians with a BMI between 23 and 25 kg/m2 as overweight and above that as obese, a slightly higher-than-normal BMI seems to be beneficial to the odds of recovering from a stroke with less disability. First author Kanejima offers an explanation: "The median age in this study was 77 and people in this age group and beyond lose weight more easily. However, people having certain reserves may be better able to withstand the nutritional challenge a stroke and the following hospitalization pose, which effectively protects their nervous system."

A similar study conducted in the United States a few years ago found the same basic effect, but with an optimal BMI of 30.0 kg/m2 for that population. "Asians tent to have a slimmer physique compared to Americans and this is also reflected in the lower optimal BMI for a lower probability of disability at discharge," says Kanejima. This underscores that caution is needed when adapting BMI-based recommendations for different populations around the world.

There is concrete advice gleaned for current health care practice from the results of the present study. Izawa says: "For the public, this serves as a reminder that losing weight at a high age is a disadvantage. For health care providers, the study suggests that they need to closely monitor weight loss during hospitalization to prevent functional impairment." To understand more about the mechanism at work, the Kobe University researchers next aim to study how the change in body weight during hospitalization is related to functional disability.

This research was funded by the Japanese Circulation Society and the Japan Society for the Promotion of Science (grants JP22K11392 and JP22K19708). It was conducted in collaboration with researchers from the National Cerebral and Cardiovascular Center.

Abstract

Objectives To investigate associations of the ‘weekend warrior’ physical activity pattern with mild dementia.

Methods Participants in the Mexico City Prospective Study were surveyed from 1998 to 2004 and re-surveyed from 2015 to 2019. Participants were asked about leisure time physical activity at baseline. Those who exercised up to once or twice per week were termed ‘weekend warriors’ and those who exercised more often were termed ‘regularly active’. A Mini Mental State Examination (MMSE) was used to assess mild dementia at re-survey. Cox models were adjusted for age, sex, education, income, blood pressure, smoking, body mass index, civil status, sleep, diet and alcohol at baseline. The attributable fraction was defined as the proportion of cases that would not exist if all adults were to exercise once or twice per week or more often.

Results The analysis included 10 033 adults of mean (SD) age 51 (10) years followed for 16 (2) years. There were 2400 cases when mild dementia was defined as a score of ≤22 on the MMSE. Compared with the group that reported no sport or exercise, the hazard ratio was 0.75 (95% CI 0.61 to 0.91) in the weekend warrior group, 0.89 (95% CI 0.78 to 1.02) in the regularly active group and 0.84 (95% CI 0.75 to 0.95) in the combined group. The attributable fraction was 13% (95% CI 5% to 21%). Similar results were observed when mild dementia was defined as a score of ≤23 on the MMSE.

Conclusions This longitudinal analysis suggests that the weekend warrior physical activity pattern is associated with a reduced risk of mild dementia.

Lower Blood Sugar Diet Linked to Slower Brain Aging

Since there is no specific factual basis for what exactly a Mediterranean diet is, maybe you want your doctor to give you a transfusion of young blood or bone marrow or brain fluid! 

Lower Blood Sugar Diet Linked to Slower Brain Aging

Summary: The Green Mediterranean diet may help slow brain aging by controlling blood sugar levels, benefiting cognitive health in older adults. The study found that lower blood sugar levels were linked to a younger brain age, particularly in regions critical for memory and sensory processing.

Using advanced MRI scans, researchers observed that participants on the Green-Med diet exhibited a slower rate of brain atrophy over 18 months. Components of this diet, rich in polyphenols from plants like Mankai and green tea, may support brain structure and function.

This dietary approach provides a potential pathway to reducing age-related cognitive decline. The findings offer promising insights into dietary and lifestyle changes as practical strategies to protect brain health.

Key Facts:

  • Lower blood sugar levels were associated with a younger brain age, delaying brain atrophy.
  • Green-Med diet, rich in polyphenols from plants, slowed brain aging in study participants.
  • The DIRECT PLUS trial used MRI scans to show reduced brain tissue loss in those with improved glycemic control.

Age-related brain atrophy, the gradual loss of neurons and shrinkage of brain tissue, is a natural part of aging, which can lead to cognitive decline and other neurological issues.

While so far aging cannot be prevented, recent research from an 18-month dietary intervention offers hope that lifestyle and dietary changes can slow brain aging.

A new international study, led by Ben-Gurion University of the Negev as part of the DIRECT PLUS Brain MRI trial, has brought to light how blood sugar control can significantly impact brain health.

This shows brain scans.

Brain age, as evaluated by MRI measurements of the hippocampus and lateral ventricles, reflects the biological aging of the brain, which can differ from a person’s chronological age. Chronological age is the number of years lived, while brain age indicates the brain’s actual health.

Typically, as we age, the hippocampus shrinks and the lateral ventricles expand, serving as markers of brain aging. Some individuals have a brain age younger or older than their chronological age.

A younger brain age suggests better cognitive health, while an older brain age may indicate accelerated aging and increased risk of cognitive decline.

The study, which was published recently in The American Journal of Clinical Nutrition 2024, was conducted by an international team of brain and nutrition experts, including researchers from Ben-Gurion University, Harvard University, Leipzig University, and more.

The research was primarily carried out by Ph.D. student Dafna Pachter and overseen by Prof. Iris Shai, along with several international collaborators.

A previous study published two years ago, reported that Mediterranean (MED) and green-MED diets significantly attenuated age-related brain atrophy by ∼50% within 18 months.

In the current study, the researchers aimed to understand the mechanism by which the slowing of brain atrophy occurs.

The study found that a decline in HbA1c, and key markers of long-term blood sugar levels, are associated with significant positive changes in specific brain regions commonly affected by age-related atrophy.

Brain MRI results showed that lower HbA1c levels corresponded to greater deviations in the thalamus, caudate nucleus, and cerebellum – areas crucial for cognitive function, motor control, and sensory processing.

The study suggests that improved blood sugar control could be one of the most important factors in slowing down age-related brain changes.

The Green Mediterranean Diet Shows Promise

Earlier research has highlighted the benefits of the Green Mediterranean (Green-Med) diet, including better blood sugar control. The Green-Med diet is rich in polyphenols from plant-based sources like Mankai (a high-protein aquatic plant) and green tea, while being low in red and processed meats.

The current study further strengthens this connection by suggesting that the Green-Med diet may not only support metabolic health but also exert protective effects on brain structure and function.

DIRECT PLUS Trial – One of the Largest Brain MRI intervention Studies in the World

The DIRECT PLUS trial, one of the longest and largest brain MRI studies conducted to date, involved approximately 300 participants who were divided into three dietary groups. Whole-brain MRI measurements were taken before and after the 18-month trial to track changes in brain health.

The researchers used Hippocampal Occupancy (HOC), as a proxy for brain age which predicts future risk of dementia. HOC typically decreases with age. Interestingly, some participants exhibited a brain age either younger or older than their chronological age.

Using NeuroQuant, an FDA-authorized fully automated tool, the research team quantified and segmented the brain MRI-derived data. The study aimed to examine whether improved glycemic control and specific dietary components could slow down brain aging.

The results indicated that participants who managed to improve their blood sugar levels and achieve normal glucose status experienced a more pronounced attenuation of brain aging.

Notably, those who consumed higher amounts of green tea and Mankai duckweed shakes demonstrated the most significant improvements in both blood sugar levels and brain health.

Glycemic Control and Polyphenols: The Key to a Younger Brain Age?

The study’s lead researcher, Prof. Iris Shai, from Ben-Gurion University, an adjunct professor at Harvard University, and an Honorary Professor at Leipzig University, explains, “Maintaining low blood sugar levels, even within the normal range, shows promise for preserving a younger brain, especially when combined with a healthy diet and regular physical activity.

“Specifically, polyphenols found in plant-based foods may cross the blood-brain barrier and help reduce brain inflammation, which is crucial for memory”.

Dafna Pachter, a Ph.D. student and the first author of the paper, adds, “This trial offers a safe approach to potentially slow down our brain aging—by adopting the components of a green-Mediterranean diet.”

A Pathway to Reducing Age-Related Cognitive Decline

This study is one of the first large-scale trials to directly link dietary changes, particularly those associated with the Green-Med diet, to improved glycemic control and slower brain aging.

While further research is needed to fully understand the mechanisms at play, these results suggest a potential avenue for reducing the risk of age-related cognitive decline through relatively simple dietary adjustments.

Funding: The DIRECT PLUS trial was funded by grants from the German Research Foundation (DFG), Israel Ministry of Health, Israel Ministry of Science and Technology, and the California Walnuts Commission.

Dr Ray O’Connor takes a look at the latest clinical papers on the treatment of stroke, and how high-quality rehabilitation can minimize(NOT RECOVER!) the impact of the condition

Globally, stroke is the second leading cause of death, and the third leading cause of death and disability combined. Around 100,000 people have strokes each year, and around 1.3 million people in the UK have survived a stroke. High-quality rehabilitation can minimise the physical, emotional, cognitive, and social impacts for people who have had a stroke, and their carers. It can also yield substantial cost savings to society.

The National Institute for Health and Care Excellence (NICE) guidance on stroke rehabilitation in adults was updated in October 2023.1 The guideline summary published in the BMJ earlier this year2 covers selected new and updated recommendations and focuses on those most relevant to primary care and community rehabilitation settings.

Dr Ray O’Connor

The main recommendations are as follows. Stroke rehabilitation total therapy time should be based on the person’s needs, with the amount increasing to at least three hours a day, on at least five days a week. Fatigue is common; use a validated scale for early assessment. Offer vision and hearing assessment. Consider referral to community participation programmes suited to the person’s rehabilitation goals.

Interestingly the American Heart Association and the American Stroke Association also jointly published stroke prevention guidelines this year3 It is an extensive document covering over 80 pages with 735 references.

The ‘Top Ten Take-home Messages’ for busy clinicians are listed. A brief summary is as follows. Everyone should have access to and regular visits with a primary care health professional to identify and achieve opportunities to promote brain health. Screening for and addressing adverse social determinants of health is important in the approach to prevention of incident stroke.  

The Mediterranean diet is a dietary pattern that has been shown to reduce the risk of stroke. Physical activity is essential for cardiovascular health and stroke risk reduction. Glucagon-like protein-1 receptor agonists have been shown to be effective not only for improving management of type 2 diabetes but also for weight loss and lowering the risk of cardiovascular disease and stroke.

Blood pressure management is critical for stroke prevention. Antiplatelet therapy is recommended for patients with antiphospholipid syndrome or systemic lupus erythematosus without a history of stroke or unprovoked venous thromboembolism to prevent stroke. Prevention of pregnancy-related stroke can be achieved primarily through management of hypertension.

Treatment of verified systolic blood pressure ≥160 mm Hg or diastolic blood pressure ≥110 mm Hg during pregnancy and within six weeks postpartum is recommended. Endometriosis, premature ovarian failure (before 40 years of age), and early-onset menopause (before 45 years of age) are all associated with an increased risk for stroke.

Therefore, screening for all three of these conditions is a reasonable step in the evaluation and management of vascular risk factors in these individuals to reduce stroke risk. Finally, the authors recommend that understanding transgender health is essential to truly inclusive clinical practice.

Treatment of acute stroke, before a distinction can be made between ischemic and haemorrhagic types, is challenging. This randomised controlled trial4 studied whether very early blood-pressure control in the ambulance improves outcomes among patients with undifferentiated acute stroke.

The subjects were 2404 Chinese patients with mean age of 70 years with stroke that caused a motor deficit and with elevated systolic blood pressure (≥150 mm Hg). The authors randomly assigned patients who were assessed in the ambulance within two hours after the onset of symptoms, to receive immediate treatment to lower the systolic blood pressure (target range, 130 to 140 mm Hg) (intervention group) or usual blood-pressure management (usual-care group).

The results were that prehospital BP reduction did not improve functional outcomes. Interestingly, 46.5 per cent subsequently received a diagnosis of haemorrhagic stroke.

Inflammation has been associated with incidence and recurrence of stroke, and risk of stroke was reduced in patients who have coronary artery disease and who were treated with colchicine. This multicentre, double blind, randomised, placebo controlled trial from China5 looked to assess the efficacy and safety of colchicine versus placebo on reducing the risk of subsequent stroke after high risk non-cardioembolic ischaemic stroke or transient ischaemic attack within the first three months of symptom onset.

The participants were 8,343 patients aged 40 years of age or older. Patients were randomly assigned 1:1 within 24h of symptom onset to receive colchicine (0.5 mg twice daily on days 1-3, followed by 0.5 mg daily thereafter) or placebo for 90 days. Unfortunately, no differences were noted in treatment effects on subsequent stroke between the low dose colchicine and the placebo groups.

Increasingly, the effects of global warming are resulting in extremes of heat. This ecological study6 considered what is the burden of stroke worldwide associated with extremes in temperature. The authors collected data from the Global Burden of Diseases Study 2019, the Climate Research Unit Gridded Time Series, and the World Bank database to estimate stroke burden attributable to nonoptimal temperature and its distributional characteristics at the global, regional, and national levels. The conclusion was that the burden of stroke attributable to nonoptimal temperature conditions continued to increase, and aging was a key factor in this increase. In 2019, 521,031 deaths and 9,423,649 disability adjusted life years (DALYs) were attributable to stroke due to nonoptimal temperature globally.               

Does Additional Education Protect the Brain?

 Anecdotally I know two persons with Ph.Ds; one which got full blown Alzheimers and the other now having MCI. I don't even have a masters, so this is concerning to me.

Does Additional Education Protect the Brain?

Summary: A recent study explored whether additional years of education lead to long-term changes in brain structure, especially in protecting against brain aging. Analyzing data from a unique natural experiment involving nearly 30,000 individuals, researchers found no detectable impact on brain structure from an additional year of education.

Although education is linked to better cognitive skills and health, it does not appear to alter the brain’s physical structure in the long run. Researchers suggest that any initial structural impact may be temporary or too small to detect with MRI technology. These findings highlight the need for caution when linking education directly to brain structure based on correlations alone.

Key Facts:

  • Education correlates with cognitive and health benefits but shows no lasting effect on brain structure.
  • The study used a natural experiment, comparing brain scans from individuals with and without an additional year of school.
  • The impact of education on brain structure may be temporary or microscopic, evading MRI detection.

It is well-known that education has many positive effects. People who spend more time in school are generally healthier, smarter, and have better jobs and higher incomes than those with less education.

However, whether prolonged education actually causes changes in brain structure over the long term and protects against brain aging, was still unknown.

This shows a brain and a graduation cap.

It is challenging to study this, because alongside education, many other factors influence brain structure, such as the conditions under which someone grows up, DNA traits, and environmental pollution.

Nonetheless, researchers Rogier Kievit (PI of the Lifespan Cognitive Dynamics lab) and Nicholas Judd from Radboudumc and the Donders Institute found a unique opportunity to very precisely examine the effects of an extra year of education.

Aging

In 1972, a change in the law in the United Kingdom raised the number of mandatory school years from fifteen to sixteen, while all other circumstances remained constant. This created an interesting ‘natural experiment’, an event not under the control of researchers which divides people into an exposed and unexposed group.

Data from approximately 30,000 people who attended school around that time, including MRI scans taken much later (46 years after), is available. This dataset is the world’s largest collection of brain imaging data.

The researchers examined the MRI scans for the structure of various brain regions, but they found no differences between those who attended school longer and those who did not.

‘This surprised us’, says Judd.

‘We know that education is beneficial, and we had expected education to provide protection against brain aging. Aging shows up in all of our MRI measures, for instance we see a decline in total volume, surface area, cortical thickness, and worse water diffusion in the brain. However, the extra year of education appears to have no effect here.’

Brain structure

It’s possible that the brain looked different immediately after the extra year of education, but that wasn’t measured.

‘Maybe education temporarily increases brain size, but it returns to normal later. After all, it has to fit in your head’, explains Kievit.

‘It could be like sports: if you train hard for a year at sixteen, you’ll see a positive effect on your muscles, but fifty years later, that effect is gone.’

It’s also possible that extra education only produces microscopic changes in the brain, which are not visible with MRI.

Both in this study and in other, smaller studies, links have been found between more education and brain benefits. For example, people who receive more education have stronger cognitive abilities, better health, and a higher likelihood of employment. However, this is not visible in brain structure via MRI.

Kievit notes: ‘Our study shows that one should be cautious about assigning causation when only a correlation is observed. Although we also see correlations between education and the brain, we see no evidence of this in brain structure.’

International group revises diagnostic guidance for Alzheimer’s

A consortium of 46 international Alzheimer’s disease experts issued revised guidelines for disease diagnosis. Image: Adobe Stock

“These recommendations are the collaborative effort of 46 international experts who emphasize that diagnosing Alzheimer’s disease should primarily rely on clinical evaluation supported by biomarkers,” Bruno Dubois, MD, MSc, of the Institute of Memory and Alzheimer’s disease in the department of neurology at Salpetriere Hospital in Paris, said in a release related to the guidelines, which were published in JAMA Neurology.

Key takeaways:

  • The guidance outlines core biomarkers for Alzheimer’s, including cerebrospinal fluid, evidence of tau protein and amyloid-beta.
  • It also includes three new terms for stages of disease progression.

The International Working Group has updated diagnostic guidelines for Alzheimer’s disease to include individuals with normal cognition who test positive for core biomarkers indicative of disease pathology.


The recommendations, which revise the organization’s 2021 guidelines, were presented at the 2024 Clinical Trials on Alzheimer’s Disease (CTAD) conference in Madrid. They permit that biological evidence may not be the sole manner in which AD can be defined, with core biomarkers being cerebrospinal fluid (CSF), amyloid-beta and tau, as well as plasma phosphorylated tau 217 (pTau-217) found via positron emission tomography.

The revisions were also intended to separate patients into two groups: individuals who display typical AD-related symptoms along with evidence of disease-specific biomarkers who are diagnosed with AD vs. those who have evidence of disease-specific biomarkers but no symptoms which predict eventual disease progression, Dubois added.

The guidelines additionally encourage clinicians to embrace three specific terms relating to disease pathology and progression.

Those deemed asymptomatic but at risk for AD:(We stroke survivors are at risk)

  • are cognitively normal but are at elevated risk for becoming cognitively impaired due to unknown risk from a biomarker profile;
  • are at increased risk for progression to cognitive impairment compared to those without biomarker presence; and
  • should not be defined as having the condition.

Individuals found to have presymptomatic AD:

  • are cognitively normal individuals who show a pattern of biomarkers consistent with a very high risk for progression to cognitive impairment;
  • possess dominant genetic variations associated with a 100% risk for development to clinical AD such as APP, PSEN1 and PSEN2; and
  • demonstrate biomarker changes, coupled with genetic risk factors, associated with elevated risk for clinical AD development such as those confirmed by PET.

Those with AD:

  • are cognitively impaired individuals with specific clinical phenotypes including aphasia, cortical atrophy along with behavioral or executive dysfunction;
  • test positive for AD-related pathology through analysis of plasma biomarkers, CSF or PET; and
  • show signs of the above in the prodromal and dementia stages of disease.

“Further developing brain health services for the prevention of dementia could lead to better evaluation of risk, communication of risk and risk reduction strategies targeting modifiable risk factors,” Giovanni B. Frisoni, MD, professor in the department of psychiatry at Geneva University Hospital in Switzerland, said in the release.

New £1m stroke rehab unit opens at Frimley Park Hospital to improve patient recovery

 THIS is what's wrong with our stroke medical 'professionals'! They start out just improving recovery, RATHER THAN DELIVERING RECOVERY! Whomever approved that needs to be fired!

New £1m stroke rehab unit opens at Frimley Park Hospital to improve patient recovery

A new £1m stroke rehabilitation unit has been officially opened at Frimley Park Hospital, while a national campaign looks to shorten the time between a stroke and dialling 999.

Funded by Frimley Health Charity and donations from the public, the new extension to the hospital is designed to improve patient experience and recovery times.

With a specially-designed garden and dedicated therapy rooms, the new stroke rehab unit allows medical staff to give the 'best care possible' to their patients.(NOT RECOVERY!)

Consultant Dr Tom Pain said: "Before this ward open all the therapy was done in ward bays and there is very little privacy so this allows the therapist to take the patients out of the ward environment to deliver the therapy sessions."

A common misconception about strokes is that they mainly affect older people, but they can happen to anyone.

The latest figures from Public Health England show the average age of stroke victims is getting younger.

Claire Woodward was admitted to Frimley Park Hospital after suffering a stroke on 14 October.

She said: "I can come into the day room to see my children and grandchildren and I use the therapy rooms with the occupational therapist - so it's made a big difference."

Around 100,000 people have a stroke each year in the UK, which occurs when the blood supply to part of the brain is cut off.

The current stroke service at the hospital looks after more than 100 people every month, and it is hoped the bigger and better unit will become a national centre of excellence for stroke care.

OT Suzanne Barber said: "Some of our patients are on the stroke ward for two to three months and being in that environment all the time is really, really difficult.

"So it just allows people to step off of the ward and not be stuck in that ward environment. Psychologically it's good for people's wellbeing."

Without fast treatment a stroke can result in death or long-term disabilities such as paralysis, memory loss and communication problems.

The new unit comes as the NHS launches a campaign which aims to improve the time between the onset of a stroke and emergency services being called.

New analysis of NHS data shows that for 2023-24, of 41,327 patients with a recorded time of symptom onset, the average time between first symptom and a 999 call being made was 88 minutes.

The FAST acronym (Face, Arms, Speech, Time) is a test to quickly identify if someone is having a stroke.

  • Face weakness: Can the person smile? Has their mouth or eye drooped?

  • Arm weakness: Can the person raise both arms?

  • Speech problems: Can the person speak clearly and understand what you say?

  • Time to call 999: if you see any of these signs.


Dr David Hargroves, NHS national clinical director for stroke and consultant stroke physician, said: “When someone has a stroke, it’s estimated they may lose around two million brain cells a minute, which is why rapid diagnosis and treatment is critical – the first sign of a stroke might not seem like much, but face or arm or speech, at the first sign it’s time to call 999.

Media medic and GP, Dr Amir Khan said: “A stroke strikes every five minutes in the UK, so it’s crucial everyone is aware of the most common symptoms of a stroke and acts FAST by calling 999.

"The first sign of a stroke actually might not seem like much, but every minute is vital – getting quick access to specialist treatment can be lifesaving and can reduce long-term disability. Whether someone is unable to raise their arm, struggling to smile or slurring when they speak – any sign is always an emergency and you need to call 999 immediately.” 

Gait Pattern in Stroke Patients and Gait Rehabilitation: a systematic literature review

I blame the supervisor for not instructing this person to map recovery protocols to each problem you have in the gait cycle. My problem really only shows up on a head on view; my left foot angles out 15% due to spasticity, causing no pushoff and heel to toe rolloff doesn't occur. My physical therapists never saw that and never worked on solving it.

 Gait Pattern in Stroke Patients and Gait Rehabilitation: a systematic literature review

1. Summary

After a stroke, patients usually struggle with physical deficits that have a direct impact on
their quality of life. Strokes cause a lot of mortality and morbidity in the population. The
challenges exist particularly for strokes survivors. Such an event in a person’s life often
brings not only physical but also mental health issues. Good motivation is crucial in the
process of rehabilitation to achieve good results.

Therefore, it should be essential to ensure accurate patient care to offer individual patients
specific procedures. It is important to be able to reintegrate people into their surroundings as
well. In that instance, recovery of motor deficits or deficits during walking should be
provided. A precise analysis of motor deficits is essential, which can be obtained in detail
using different assessment methods. This also determines the further course of therapy
options or effects of different therapy options on individual stroke patients. A basic
understanding of normal gait physiology in humans should play a role for every participating
therapist. This is particularly useful to be able to evaluate pathological gait patterns and to
recommend appropriate therapy options.

Furthermore, precise gait analyses should be carried out to record different gait parameters.
The different problems of patients are often very specific.

Gait rehabilitation can utilize many different strategies today. It is helpful to ensure a basic
need for different therapy options that positively influence different factors such as gait cycle,
stride length, step width, cadence, endurance, balance, motor deficits, step length, mobility,
etc.

Guidelines often give an approximate idea of what a therapy plan can look like. In addition,
to classic physical therapy, therapies such as proprioceptive neuromuscular facilitation,
different motor learning techniques and context- or task-specific training can be used.
Functional electrical stimulation has been used for stroke patients for many years and has
proven its effectiveness. Basic training of the complex gait cycle through treadmill training is
a crucial step in gait rehabilitation. In the next few years development of new methods may
find their way into gait rehabilitation.
