A new high-tech bracelet, developed by scientists from the Netherlands detects 85 percent of all severe night-time epilepsy seizures. That is a much better score than any other technology currently available. The researchers involved think that this bracelet, called Nightwatch, can reduce the worldwide number of unexpected night-time fatalities in epilepsy patients. They published the results of a prospective trial in the scientific journal Neurology.
SUDEP, sudden unexpected death in epilepsy, is a major cause of mortality in epilepsy patients. People with an intellectual disability and severe therapy resistant epilepsy, may even have a 20% lifetime risk of dying from epilepsy. Although there are several techniques for monitoring patients at night, many attacks are still being missed.
Consortium researchers have therefore developed a bracelet that recognizes two essential characteristics of severe attacks: an abnormally fast heartbeat, and rhythmic jolting movements. In such cases, the bracelet will send a wireless alert to carers or nurses.
The research team prospectively tested the bracelet, known as Nightwatch, in 28 intellectually handicapped epilepsy patients over an average of 65 nights per patient. The bracelet was restricted to sounding an alarm in the event of a severe seizure. The patients were also filmed to check if there were any false alarms or attacks that the Nightwatch might have missed. This comparison shows that the bracelet detected 85 percent of all serious attacks and 96% of the most severe ones (tonic-clonic seizures), which is a particularly high score.
For the sake of comparison, the current detection standard, a bed sensor that reacts to vibrations due to rhythmic jerks, was tested at the same time. This signalled only 21% of serious attacks. On average, the bed sensor therefore remained unduly silent once every 4 nights per patient. The Nightwatch, on the other hand, only missed a serious attack per patient once every 25 nights on average. Furthermore, the patients did not experience much discomfort from the bracelet and the care staff were also positive about the use of the bracelet.
These results show that the bracelet works well, says neurologist and research leader Prof. Dr. Johan Arends. The Nightwatch can now be widely used among adults, both in institutions and at home. Arends expects that this may reduce the number of cases of SUDEP by two-thirds, although this also depends on how quickly and adequately care providers or informal carers respond to the alerts. If applied globally, it can save thousands of lives.

[Mini Review] No distance between disabled people and rehabilitation engineer in high-tech era – Full Text PDF
Traditional face to face diagnosis and treatment model has existed for thousands of years between doctors and patients. But now high technologies have brought people great convenience in many fields. When the disabled people concerned, many technologies such as internet, remote sensing, signal processing, Virtual Reality and so on, are already playing an important role in rehabilitation engineering. This paper introduces these emergency new technologies associated with the disabled people and engineers in recent years, which can eliminate the psychological and space distance between disabled people and rehabilitation engineer in high-tech era.
The rehabilitation strategies are needed to optimize function and
reduce disability of disabled people. Many public plans are developed
in some countries . And now lots of specialized institutions for the
rehabilitation of disabled people have been established . The disabled
people is widely distributed , so many scholars are committed to
provide a rehabilitation approach to them . Remote rehabilitation
is a combination of rehabilitation medicine, computer technology,
internet technology, sensor technology, information processing
technology, etc., it is a new rehabilitation resources with a new concept
of rehabilitation, which can provide space for the further development
of rehabilitation engineering technology . Based on the realization
of cross-regional rehabilitation services, remote rehabilitation is
the integrated use of communication technology, remote sensing
technology, remote control technology. Remote rehabilitation allows
people to achieve rehabilitation cross the geographical area via the
information exchange. The value of remote rehabilitation is also
reflected in the fact that it can optimize the configuration of manpower
and materials. In fact, for individuals with disabilities, rehabilitation
affected by many factors such as their family, their mood, social
environment , especially today’s high technologies.
Rehabilitation engineers can hear the voice of distant people through
the microphone and touch the distant people via embedded artificial
sensors into skin to get the signal such as the surface temperature,
moisture distribution of disabled people . Rehabilitation engineers
can also operate medical and rehabilitation equipment by the remote
control system . With the aid of a remote rehabilitation system,
information interaction between rehabilitation engineers and disabled
people can be more flexible, efficient and convenient . In addition,
other technologies, such as wearable technology , gait analysis
technology , synchronous audio-visual technology  and so
on have been already implicated in the field of remote rehabilitation
engineering. In the following paper, several important high technologies
for remote rehabilitation will be systematically analyzed via contacting
the traditional rehabilitation engineering. […]
Rohan O’Reilly is a movement therapist in Newcastle, New South Wales, who has been using alternative therapies involving virtual reality devices to help his clients with rehabilitation.
“It really came back to the point of listening to people’s stories who had had large-scale traumas, and their experiences of what they went through, from their initial accident through to therapy,” Mr O’Reilly said.
“For most of them it was really [boring] and quite uncomfortable and not inspiring.
“So we thought ‘We need to make this feel better’.
“Lucky for us we’re living in a time where there’s an amazing new array of technologies that are not widely known about.
“Virtual reality would be the one that’s hot at the moment, and essentially that is a game changer. It’s phenomenal what can be done with that as a platform for putting people in a state where they want to play.”
Making therapy fun
Mr O’Reilly said virtual reality helped clients to exercise their bodies in non-traditional ways.
“It’s about emotions,” he said.
“If your rehabilitation just tended to be based around the fact that you had to pick up an inanimate object, which you had no real emotional connection to, repetitively … for most people, they would think ‘OK, I can do this for a little while’, but they’re quickly going to run out of steam.
“If you put someone in virtual reality with everything that reminds them of the things that they love to do, they’re essentially just going to give themselves therapy.
“We’re just simply creating an environment where they can explore their own capabilities.”
Client notices big improvements in health
Almost four years ago, Angus McConnell had an accident that changed his life.
He was riding his bicycle down a hill in Newcastle when a car turned across him.
“I hit the windscreen, bumped off down the road, and ended up with a spinal cord injury — a C7 complete quadriplegic,” Mr McConnell said.
“It hits you on and off, and still does.”
Mr McConnell went through traditional hospital rehabilitation, but was looking for other options to continue his treatment.
“As your journey goes along, you want to work out whether you’re going to ignore the parts of the body that aren’t working, or you’re going to make them move,” he said.
Mr McConnell said he had noticed big improvements in his health after the alternative therapy.
“Originally we started on building up the muscles and hopefully a nerve signal that’s coming through,” he said.
“I can feel further down into my body, with electrodes on parts of my body where the nerves come close to the skin.
“I’m standing up now with the help of electrodes, and that’s something I hadn’t thought possible two-and-a-half years ago.”
Academic says VR effective, but people should be cautious
Associate Professor Coralie English, a stroke researcher at the University of Newcastle, said people should approach alternative therapies with a degree of cautiousness.
“There is a reasonable amount of evidence for the effectiveness of virtual reality training for people after stroke,” she said.
“This sort of therapy is useful for people who’ve already got some movement. There’s certainly no evidence to suggest that if you can’t move at all, trying to move within these environments is going to result in any recovery of function.
“It needs to ensure that the person is practising what they need to practice, and that it’s based on a thorough assessment by a qualified health professional.”
