Ergonomics vs the iPad

Friday, January 29th, 2010

In case you’ve been asleep over the last two days, the big technology news has surrounded the launch of Apple’s new iPad.  There seems to be a great deal of debate at the moment as to whether it will be as successful as some of Apple’s previous products (such as the iphone and itouch) – but if it’s even half as popular, it will mean a lot more people will be using a tablet based product rather than traditional books, newspapers and magazines.  So is the ipad good or bad news for ergonomics? And will it be better for your back than, say, a netbook?

At Posture People we are always interested in the release of new technology. During our lifetimes we have seen a movement within society from general ignorance (i.e. a large proportion of people not even knowing how to turn on a personal computer), to a much more widespread embracing of technology in the home. In fact, the majority of homes will now have the obligatory PC or Mac in the corner of the living room.  The adoption of all this new technology has also had a profound effect on our bodies, with more people than ever suffering with back issues.

Just in case you don’t know much about the ipad

If we look at the dimensions of the ipad, it’s slightly smaller than an A4 piece of paper, about as thick as a notepad, and flat.   It is being described by Apple as the best way to view web, email, photos, books and magazines.  But is it good for our backs?

Ipad vs the traditional book

We believe that one of the applications the ipad will become most popularly used for is as an electronic reading device. Because the ipad device is very flat, and if people use it flat on a desk to read, then the posture adopted would become largely hunched.  Look at the two photos below, and the comparative postures; when reading a book at a tipped angle, the angled book encourages a straight spine,

whereas the flat book, as though reading from a flat surface, encourages a ‘C shaped’ spine, placing increased pressure on the upper spine as it holds the weight of the head in a forward angle.

So how easy will it be to maintain holding the ipad at a tipped angle?  It will weigh 0.68 kg for the version that includes wi-fi – considerably heavier than a paperback.  So will the temptation be there to sit over it rather than tip it up?

What can help?

There are a number of products designed primarily for laptops that would work equally well for improving the ergonomics of the ipad.  If the ipad was being used as a reading device, then a laptop stand such as the cricket would be great.  The cricket laptop stand is highly adjustable, so the user could set a shallow angle to establish a good reading position. Another product, the Posture Pouch, would also work well, and would provide additional protection for your ipad, by wrapping round the ipad (see image below).

The benefit of the Posture Pouch over the Cricket Laptop stand is that the Posture Pouch can also provide a solid and appropriately angled platform upon which to write upon the ipad’s screen.  So it could compensate for the downward slope of your legs, and it would avoid the need to sit cross legged to keep the ipad from slipping off your knee.

Ipad v’s Netbook

At Posture People we are not big fans of netbooks unless they are being used for very short periods of time. The combination of a small screen and a small keyboard are, ergonomically, a recipe for disaster, as you have to bend down considerably to use the screen and the keyboard together.  So, the ipad is a marginal improvement as the screen is a little bigger, however, to create a really good ergonomic posture you will still need to raise the screen, and plug in a separate keyboard and mouse if using it for applications such as email. And remember, investigate ways of angling the screen if you are using it as a reading device.

We cannot resist the unstoppable march of new technology, but somewhere along the journey we’d like all manufacturers to investigate ways of helping their users to maintain better posture when using their devices.  One thing is for sure – the ipad is here to stay, and in the future we will undoubtedly be reading more of our words from screens rather than paper. Hopefully though, we’ll be able to do so at an angle that’s kind to our necks.

So what exactly happens in an Alexander Technique Lesson?

Friday, January 15th, 2010

There has been a lot reported in the press about the benefits of Alexander Technique in helping back pain.  The research reveals that following 24 AT lessons, the average number of activities limited by low back pain had fallen by 42%, and the number of days in pain had decreased from 21 to 3 days per month one year after the trial started. Also a series of 6 lessons followed by GP-prescribed general exercise was about 70% as beneficial as 24 AT lessons alone.  I read the actual study published by the BMJ, and a subsequent research article on the cost effectiveness to the NHS – and both studies did conclude that the Alexander Technique was beneficial over a longer period of time to helping people manage and reduce back pain.

At Posture People we’ve heard a lot of anecdotal evidence about the benefits of Alexander Technique, but until recently hadn’t actually experienced it for ourselves, and if you had asked me two days ago I would have described it as doing certain actions like sitting in a chair, over and over again until the correct way of doing it was drummed into you.

I actually think Mark Claireaux from Alexandertechniquebrighton.com must have overhead me describing it, and offered to show me what was actually involved in a lesson.

The lesson started with an overview of what the Alexander Technique is, and in a nutshell it’s a re-education of your muscles to provide better support for your body, and a way of eliminating poor habits you’ve picked up through the years.  A lot of the lesson was based around learning how to sit on a chair correctly, but as Mark explained that it’s something we do many times a day without even thinking about it. We use most of our co-ordination in this simple movement, i.e. bending at the ankles, knees and hips and the co-ordination of the head neck and back. If we can improve the way we do this simple activity with less tension and better co-ordination we can apply this to every activity we do during our day from our journey to work, through to sporting activities.

As the lesson progressed I learnt that as toddlers we are nicely balanced, our big heads wonderfully supported and everything all pulling together as it should, then somewhere along the way it all starts to go wrong.  We pick up bad habits from our parents, poor furniture at schools and the killer – our love affair with the computer; combine all that with a more sedentary lifestyle and bang it’s not surprising that more people than ever before are suffering with postural problems.

Mark explained “The Alexander Technique is unique in that we can start to eliminate bad habits that maybe doing us harm as we go about our daily lives. We are learning to move more efficiently and effectively. You may have a habit of twisting when sitting or getting drawn down into your computer or work station, you might notice that you respond to cold weather by hunching up your shoulders, you may also do this when stressed. As your awareness improves you may start to notice how stress manifests itself in your body and make a choice NOT to react in your old habitual ways. People often report that they feel calmer and more relaxed which often means their breathing has improved. If you go to the gym, play sports or are involved in yoga/tai chi or dance you will be able to apply what you have learnt in your lessons to how you move in your activity. Many people feel it really improves their performance, so you can see there is much more to the Alexander Technique than pain management it is more like getting the tools for life”

So Alexander Technique helps to re-educate our bodies, and the muscle that got the most use during this lesson was definitely my brain, as I really did have to think about even simple activities like sitting down in a chair, and how by making small changes I could be much more efficient in how I was performing the task.

Do I think it would work?  I can definitely see the benefits, but this is not a quick fix, as one lesson would definitely not cure a lifetime of poor habits.  So a course of lessons would definitely be needed to see a real difference, and even then you would have to commit to changing your habits on a long term basis to keep reaping the rewards.

But even after one lesson I left feeling more refreshed and taller, and minus the headache that I walked in with.  Also one effect I hadn’t expected was my mind felt full of ideas again.  I do believe it’s a good idea to take time out and focus on what might be affecting your performance, and if your body is working against you, Alexander Technique would be a great method of redressing that balance.
