And breathe: the computer games helping kids relax

On the unassuming second-floor office of a tech startup in Clerkenwell, London, Simon Fox is teaching me how to breathe. “You’re not trying to shove your stomach out with muscular force,” advises the design director of BfB Labs. “Instead, what you’re trying to do is feel your lungs expanding into your body. You don’t want to breathe hard, but you do want to be breathing into the bottom of your lungs.”


Clipped to my earlobe is a tiny heart-rate monitor, linked to a Bluetooth device that is attached to my T-shirt. I’m here to try out what Fox and his colleagues have dubbed emotionally responsive gaming (ERG): computer games designed to increase players’ resilience to mental health problems by using biofeedback to monitor and reward their ability to remain calm under pressure.


Between rounds in Champions of the Shengha, the company’s first offering, gamers must spend about a minute practising the kind of diaphragmatic breathing that is widely recommended as a relaxation technique; the more successfully they control their breathing, the more gems they win to spend on weapons and spells to defeat their opponents. In fact, it’s not the breathing itself that is tracked, but the player’s heart-rate variability (HRV), which increases in response to diaphragmatic breathing and lower levels of stress. A higher variation shows a body with a healthy ability to relax and respond to events.


That sounds pretty easy, I think, especially as I’m not really bothered how I fare in the fantasy-themed battling game (“Like Top Trumps but with way more interesting stuff going on,” is Fox’s explanation to a non-gamer). On my first attempt, I get four gems out of a possible 10; not bad for a first try, says Fox, who cites his own experiences of chronic anxiety as a driving force in his work. I’m determined to do better next time.

Champions of the Shengha began life more than two years ago, when Shift, a charity that works on behaviour change and social problems, was looking for a way to boost young people’s wellbeing in response to growing evidence of mental health issues among school-age children. It hit upon a computer game as a way of making the prospect of being trained in “emotional regulation” an attractive one, and was awarded £200,000 funding by Google’s Impact Challenge scheme.


Shift later incubated BfB Labs, which took on the development of the game. Keeping it genuinely enjoyable and credible as a game in its own right has always been key; ERG is being marketed to gamers not so much on the basis of its health benefits, but as an exciting new challenge.


“Half of all cases of mental health disorder start by the age of 14, and three-quarters by 24,” says Naomi Stoll, the project’s lead researcher. “Meditation, mindfulness and yoga are not the kinds of things that teenage kids, especially teenagers from disadvantaged backgrounds, are going to think are relevant to them and practise. Even 20 minutes of breathing every day is just not fun in any way.”


In a randomised control trial at the Billericay school in Essex earlier this year, more than four-fifths of the 90 pupils who played the game could reliably double their HRV through focused breathing. Three-quarters reported getting better at staying calm within the game, and a quarter said they had started using the techniques in everyday life.

The school had already seen a good take-up of mindfulness sessions, says deputy head Charlotte Berry, but it has mainly been girls, whereas Champions of the Shengha, which is played on a phone or tablet, has been embraced by both boys and girls.


“They very quickly started talking about how they were using the breathing in other aspects of their lives,” she says – including before important football matches, on occasions when they feared they would lose their tempers, and to deal with stress. Twelve-year-old Ryan Gibson used diaphragmatic breathing before his end-of-year exams and says it has also been handy at home: “I’ve got a younger sister who always annoys me. I use it to stop myself from reacting and saying something that would get me in trouble.”


Although there are a handful of other developers producing computer games that feed players’ emotions back into play, it’s a tool in its infancy. But gaming seems to have a wider role in promoting good mental health, says Dr Paul Cairns, a reader in human computer interaction at the University of York. “We feel better when we have a feeling of competence and autonomy,” he says. And games, unlike real life, present well-defined problems that are designed for people to succeed at: “They offer us the rewards we need.” Crucially, they also provide an escape from isolation, especially when you can play against people around the world online.


BfB Labs is planning future games to appeal to different audiences: Fox describes one as a “noir-y detective thing” where you have to keep your cool through a series of interrogations. Champions of the Shengha has just gone on sale on the crowdfunding site Indiegogo, where a beta version, including the biofeedback sensor, costs about £27, and there are also options to donate the kit to schools.


Back in Clerkenwell, Fox instructs me to place my hands on my chest and stomach to see which bits are moving as I breathe. I may not be engaged with the game itself, but it appears my naturally competitive nature is doing a fine job of ramping up the pressure: I overbreathe noisily. Only on my seventh try do I finally manage a five.


The next week, with multiple deadlines looming, I find myself absent-mindedly moving my hand to my stomach and adjusting my breathing. Something, it seems, has stuck.

Personal computer 3D printing used to generate new hip

Douglas Dunlop, consultant orthopaedic surgeon, mentioned: “The benefits to the patient by way of this pioneering procedure are numerous.


“The titanium utilised to make the hip is much more resilient and has been printed to match the patient’s precise measurements – this need to increase match and could decrease the chance of obtaining to have another surgery.


“The bone graft material that has been employed has outstanding biocompatibility and strength and will fill the defect behind the bone nicely, fusing it all together.”


Professor Richard Oreffo, at the University of Southampton, mentioned: “The 3D printing of the implant in titanium, from CAT scans of the patient and stem cell graft is cutting edge and delivers the probability of enhanced outcomes for individuals.


“Fractures and bone loss due to trauma or illness are a considerable clinical and socioeconomic problem. Growing bone at the stage of injury alongside a hip implant that has been made to the precise match of the patient is fascinating and offers genuine opportunities for improved recovery and quality of existence.”


Mrs Richard said: “The way medicine has evolved is amazing. I hope that this will be the final time that I have to have a hip operation. I truly feel enthusiastic to have this pioneering surgery and I can see what a benefit it will have to me.”


The 3D printing technique has previously been utilized to develop a new jaw and a new pelvis for sufferers.


A similar technique has also been employed to develop a 3D printed customised hip substitute for a 15 year outdated Swedish woman by Belgium-based implant company Mobelife, enabling her to stroll once more.

Chiropractors" spine-chilling warnings about computer systems, phones and pancakes | Michael Marshall

Scaremongering more than new technological innovation has been all around as long as technology itself, but it sank to a new low last month when The Telegraph published the following:



Computers blamed for children’s undesirable backs


Computers and mobile telephones are triggering an improve in back problems for teenagers, with 40 per cent of youngsters struggling soreness, a examine has claimed.


Researchers warned parents that their teenagers are at escalating threat from back or neck pain due to sedentary lifestyles and excessive use of technology.



The coverage was based mostly on a press release from the British Chiropractic Association as element of its “Engineering and Teenagers” awareness campaign. The BCA’s press workplace informed me that the study was an opinion poll conducted by a industry research firm, but they declined my request to look at the inquiries that had been asked or the several decision solutions that had been offered.


However, it appears the researchers questioned mothers and fathers of 11 to 16-year-olds about their child’s technological innovation usage and whether their children had ever seasoned back pain, and then invited them to speculate about what might have brought on the discomfort. That the methodology concerned no actual examinations of the kids – either by spinal authorities or chiropractors – significantly undermines the findings.


It comes as no surprise that the full research is not offered to the public, allow alone published in a respectable journal. Yet this flimsy research is apparently adequate to base an complete awareness-raising campaign on, one particular which the media readily picked up.


This technique has worked not only for the BCA, but also for other chiropractic organisations. In March, the United Chiropractic Association went one further than the BCA, releasing a press release that inspired the Daily Mail to declare the humble smartphone to be a prospective killer:



Could sending texts Kill you? Messaging may possibly lead to heart condition and breathing troubles in later existence, examine claims.


Texting and employing mobile products for long intervals of time could lead to a decrease life expectancy, in accordance to a new study.


Chiropractic experts feel the hunching posture adopted by phone or tablet end users can result in breathing difficulties, top to cardiovascular problems later on in daily life and a increased threat of death in older age.



The hyperlink amongst hyperkyphosis, a deformation of the spine usually connected with degenerative circumstances this kind of as osteoporosis, and the posture adopted even though studying emails looks to be the invention of the UCA – it undoubtedly is not supported by any reliable evidence. Quite how our smartphone-reading through posture differs from the bog-common book-studying posture we’ve adopted for centuries is anyone’s guess.


That the Mail reported the UCA’s press release with no a trace of criticism – or, indeed, proof – is undoubtedly poor journalism, and it comes as no shock that its story was rapidly derided by experts.


The campaign comes soon after many years of criticism for chiropractors: in 2010, the BCA lost an costly legal case following suing science writer Simon Singh (who is now my colleague at the Excellent Pondering Society). The BCA was unhappy with his criticisms of claims produced by the association and its members that spinal manipulation – which according to chiropractic concept can unblock “subluxations” in the innate power of the spine – could deal with colic in infants. (There is no dependable proof that spinal manipulation can deal with infant colic.)


Despite this substantial-profile defeat in the courts, a lot of chiropractors – such as some members of the BCA – still routinely distribute leaflets at their practices containing claims that chiropractic remedy can manipulate the spines of newborn infants to deal with colic, breathing problems, ear infections, poor appetite and even allergies. That BCA members even now appear to, in the phrases of Singh, “happily advertise bogus treatments” for which there is “not a jot of evidence” is alarming to say the least. Chiropractors may possibly nicely feel that they are assisting their individuals, but the ideal offered proof does not support their bizarre theories.


The apparent inaction of the chiropractic regulatory bodies is troubling. In the wake of publicity induced by the libel action towards Singh, the sector came below intense scrutiny, with complaints of misleading or unsubstantiated claims levelled against one in 3 registrants of the Common Chiropractic Council. Four years on, it looks minor has been done to discourage chiropractors from making unsubstantiated claims – the GCC seems to be as ineffective as the treatment options provided by its members.


Even though the regulatory side of the chiropractic business has been slow to act, the exact same can not be explained of its advertising and PR departments. Apart from scaremongering more than our deadly smartphone usage, we’ve also been subjected to press releases warning of the dangers of sleeping on poor mattresses, more than-stuffing our ‘man-bags’, and even flipping pancakes.


If chiropractors want to be taken significantly, perhaps they ought to emphasis on bettering the regulation of their market and conducting rigorous study rather than relying on PR stunts to drum up company. But I suspect they will carry on to bend in excess of backwards to exploit every PR opportunity.


In the meantime, the newspapers who merrily regurgitate these flimsy stories should be careful: if they stoop any lower, they’ll put their backs out.

81-year-old patient "left in agony as physician played on computer"


Her son, Gary, 52, went to request for pain relief but was advised that the medical doctor in the corridor, who was ‘playing on a computer’, was ‘not on this morning’, her inquest was informed.




Right after two hours of extreme discomfort, Mrs Gray was lastly provided morphine. She died a couple of weeks later of complications from the surgery.


Her daughter, Susan Carter, told the inquest at Manchester town hall that she believed her mother ‘could be alive’ nowadays if not for hospital errors.


Coroner Nigel Meadows, recording a narrative verdict, stated that Mrs Gray died from multi-organ failure following problems following bowel surgical treatment, but also mentioned a quantity of failures in nursing care.


Mr Meadows stated: “I can see… a variety of failures in nursing care. It can not be said they had been physically a result in of her death. The pathologist is saying the perforation of her bowel led to multi-organ failure.”


A 41-web page hospital report showed lapses in nursing care in nutrition and hydration, soreness management, infection prevention and record-keeping. The inquest was advised that the report showed the hospital had taken the situation seriously.


After the inquest, Mrs Gray’s son Gary stated: “It’s a catalogue of mistakes and only tells us what we already knew, but perhaps the hospital will find out for potential households.”


A hospital spokesman mentioned: “Mrs Gray was provided discomfort relief immediately following her procedure and a medical professional was then named to provide a more powerful painkiller and attended to Mrs Gray an hour-and-a-half later. An additional doctor who was present on the ward at the time was from a going to speciality and not acquainted with Mrs Gray.”
