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.

Fall detector for older people

This would seem to be incredibly important for stroke survivors. But I bet it is not important enough for your doctor and hospital to follow this and get it in the outpatient department as soon as it is available.
This may have caught the fall where I slid under the car in winter trying to clear snow off.

New sensor will make life safer for the elderly
Pressure measurements enable a newly developed fall detector to “observe” falls that current sensors do not register, thus improving safety for older people who live at home.
Technology and health: Many elderly people would like to live at home as long as possible, but to do so, they need to feel safe. A new fall detector that SINTEF researchers are helping Tellu AS to develop will improve their level of personal safety. It is capable of detecting all types of fall, even sinking falls, which currently available products do not register.
This type of fall is particularly difficult to detect because the g-forces involved are small, since the falling movement takes place almost in slow motion. A sinking fall doesn’t involve significant g-forces; “in a sinking fall, the victim may simply slide down a wall or off the edge of a bed, and end up sitting on the floor,” says SINTEF scientist Anders Liverud.
Registers all stypes of fall
The newly developed fall detector registers falls by comparing pressure changes between a sensor attached to the user’s upper body and others installed at various points around the house.
When the pressure in the sensor attached to the body rises, it notes that the user is falling,” explains Liverud, who points out that the sensor will detect the fall no matter how rapidly or slowly it takes place.
“Unlike ordinary barometers, which measure absolute atmospheric pressure, our sensors measure changes in pressure. This provides much more accurate readings that are sensitive to changes in altitude of as little as one centimetre, enabling the detector to register all changes in the position of the user.
The pressure measurement technology involved is not new as such, being the same as aircraft use to register changes in altitude, but this is the first time it has been employed in a fall detector.
Filters changes in pressure
The biggest challenge faced by the researchers involved finding a method of filtering out pressure changes that are not due to a fall, such as a door being opened or a ventilation system being switched on.
“Here, we have arrived at a number of smart solutions that enable us to distinguish between falls and pressure changes due to other causes,” says Tellu’s development manager Knut Eilif Husa, who prefers not to say anything more specific at the moment, as the company has applied for patents on several of its methods.
Current pressure sensors rely on measuring acceleration and orientation, which means that they are dependent on a certain level of acceleration and on ending up in a horizontal position in order to register a fall.
“Such sensors tend to be inaccurate, because they do not register all actual falls but may also report too many false alarms,” explains Husa.
Will ensure instant help
Through the HEADS project, which is financed by the European Union, the research team has developed a software platform that checks that all the units are operating reliably, thus enabling the fall detector to communicate with an emergency centre.
Bluetooth technology connects the sensor to a safety alarm device or telephone so that the user can count on receiving help almost immediately.
“If you do fall, a rapid response is vital. Research has shown that injuries become more serious the longer you have to wait for help. By reducing the time between falling and getting assistance, we can reduce the rates of both morbidity and mortality.” says Liverud.
More people will be able to continue living at home
Today, fifty per cent of the alarms received from manually triggered safety devices are due to falls, which are the largest single cause of accidents in the home, and falls often lead to elderly persons being institutionalised.
Many people who fall enter a vicious circle, as they isolate themselves in their homes, no longer dare to leave the house and more easily lose their sense of balance, making them more likely to fall again. Solutions of this sort that reassure people that their falls will be registered by the system are very valuable, and are an important means of enabling them to live longer in their own homes, say the researchers.
“We have put a great deal of effort into this topic in recent years, but the technology has not been mature enough until now. We believe that this fall detector will offer elderly people a sense of security that will enable them to lead an active life without supervision” says Liverud.
Box 1: The World Health Organization has estimated that about a third of all persons over the age of 65 fall every year, and that 50 per cent of all injury-related hospital admissions in this group are due to falls. Around 40 per cent of all deaths resulting from injury are due to falls.
Box 2: SINTEF and Tellu AS have developed and tested the fall detector in the course of a one-year pilot project financed by the Oslo Regional Research Fund and the European Union’s HEADS project, which develops software platforms for “Internet of Things” (IoT) applications. SINTEF and Tellu are currently applying for further funding for a main three-year project that will prepare the fall detector for the market, by when it will be capable of being incorporated into all types of safety alarm system.
According to the Norwegian Directorate of Health, 73,000 safety-related alarms were registered in 2010 in Norway. This figure is expected to increase significantly in the next few years as more and more new welfare technologies become available.
