“Tweeting by thought alone is a somewhat slow process using this prototype technology –- we speak at approximately 120 words per minute. But, as with texting, users can improve as they practice using the interface. “I’ve seen people do up to eight characters per minute,” Wilson says.”

Ouch.. that would be a significant downturn in workload!  I can see this form of input being a considerable benefit to people with severe disabilities, however I do wonder what the long term health impacts are of having an electrode implanted in your brain. My guess is that it must surely at this stage be a large unknown. It is, however, an interesting area of research.

I may not be a medical professional, but I am able to tell when I encounter descriptions of body motion that just make plain sense, and this DVD contains some enlightening information. In a collection of well narrated chapters complete with diagrammatic video illustration, the evidence is laid bare of our common tendencies to keep our bodies out of balance, causing pain through muscle tensions that, in turn, keep our bodies in bad posture. This is due in part to us having mapped the body in a particular way, eg in relation to position, when in reality the position is entirely different.

This DVD is broken into multiple sections covering the many aspects of posture imbalance, and covers areas from the head to the feet and just about everywhere in between. Posture is translated by the authors as ‘Body Maps’ which are essentially memories in your mind of where you think your individual body parts are and how you use them. The DVD highlights how you may have had a flawed map (understanding) of your various body parts in your mind from a very young age. This may have led you to actually move according to those flaws and results in the straining of some parts of your body which can lead to pain. As the narrator tells us, “We move in the way in which we think we are constructed …”, either consciously or unconsciously. Wrong body maps can be responsible for many bad posture related problems, from walking to sitting, to using a computer.

Subjects covered in the DVD include -

• Body maps – identifying flaws in the human body map and how to recognise those errors
• Balance – identifying correct balance with core posture, and identifying posture related pain
• Kinesthesia – learning free and fluid movement to correct body imbalances
• Arms – covering shoulders, elbows,  wrists and hands
• Legs – covering hips, pelvis, knees and feet
• Breathing – covering lungs, skeletal/muscular system, diaphragm
• Mapping the whole body
• Correcting the map
• Inclusive attention

The areas I can relate to most pertain to the shoulders, arms, wrists and hands. These are covered in detail and are very applicable to the RSI sufferer. The main posture/skeletal issues with RSI type injuries are listed, adding to the viewer’s knowledge and understanding through plain and straightforward explanations along with clear diagrams and video.

From previous experience, I knew that over-supination of the wrists was a bad thing, but now I know about the natural axis of rotation of the forearm and how it ties in with a neutral position wrist, as well as why supination causes so many injuries.

The company website rather generously shows sample videos of some chapters which are well worth checking out, and will give you a sneak peak of the DVD content and style as well as some key body map information!

• ‘Elbows’ chapter
• ‘Arms’ chapter
• ‘Forearms’ chapter
• ‘Hands’ chapter
• ‘Lower Back’ chapter
• ‘Balance’ chapter
• ‘Lungs’ chapter

I also found the section on breathing very interesting. It’s probably the first time I’ve been able to picture the role of the diaphragm in breathing, and I certainly had my lungs mapped as being a bit lower than they actually are. The related section on the ribcage was also revealing to me having just recently strained my sternum connective tissue whilst gardening. It  also reinforces the benefits of some breathing practices including Yogic breathing (Pranayama).

The DVD run time is a substantial 2hrs,  and certainly lends itself to being watched in stages. There is the temptation to skip straight to the section you are most interested in, however it should be watched as a whole to get the complete picture and overall message firmly ingrained in your mind. I expect that multiple viewings would be best to fully absorb the detail.

All in all this DVD is an excellent resource for just about everyone. It is not solely aimed at one specific group of people eg RSI sufferers, but covers the whole body, and should be a useful education tool for everyone, including ergonomists, physiotherapists, fitness instructors, yoga teachers etc, as well as many others including in the medical profession.

If you have posture related pain it’s likely that it’s down to your bad body map and it’s certainly time to re-educate yourself!

The reason that developments like this are exciting is that the games business, being a cutting edge, technologically advanced industry, usually pushes the boundaries of software and hardware development for the sake of market share.

Technology like this for, say, computer controls would ordinarily evolve a lot slower if there were a lesser need for it aside  from gaming. However, once developed, you can see how it could easily transform into some kind of gesture control for computer operating systems and applications. Who knows, you may even get a workout whilst doing a spreadsheet in the future!  Will a workout mat eventually replace the old desk?  Maybe we can eliminate the need for going to a gym!  Do employers only hire fit people in the future?

We are certainly at a crossroads with computers, where the basic mouse has been around too long and has created too many overuse injuries. It is more than time that we took computer input to a new level of evolution, and this may be the glimpse of what’s to come.

Whether this technology can save us from RSI related injuries is unknown, but it may help wean us off using a mouse. It may also lead to opportunities in computer use for people with all kinds of different disabilities, and not just RSI.

Is this the dawn of a new age in computer ergonomics, or is it just a gimmick ?

Previously, while living in the US, I was sent for Bio Feedback monitoring, and was ‘hooked up’ to many electrode pads around my neck, shoulders, and arms. These were to be used to measure muscle tension in all the upper body limbs including the neck and shoulder area.  The sensors are connected to a computer which plots out the associated muscle tensions on a monitor, so you have real time visualisation of the various muscle tensions you hold in your upper body when operating computer equipment. You are actually seated in front of a real keyboard and mouse, and asked to type and enter data like you normally would in your daily life.

I was actually quite surprised at how much tension the signals showed, and was constantly told to relax the posture to drop the tension levels – not an easy task!

I had to really try to relax my whole body from my head to neck to shoulders to arms to wrist angle to make even the slightest difference. The difficulty was trying to hold it there whilst typing and using a mouse.

Emphasis was placed on relaxing muscles that control the upper limbs, as well as suggestions on how to become more relaxed in the mind both inside and outside of the office environment.

As with other RSI awareness education therapies, there was no magic bullet for me with Bio Feedback, but it certainly helped to raise my awareness of how tense my upper body limbs (including shoulders) became while operating computer equipment, and that really is an important part of the RSI education process.

There are a lot of braces out there, and what works for one person may not work for everyone. Braces are usually made out of neoprene or elasticated material coupled with a metal or hard plastic support to immobilise the wrist.

The primary use of the wrist brace should not be forgotten ie to rest wrist joints and forearm muscles that drive the wrist motion (forearm extensors, flexors), and reduce the pain associated from overuse injuries. While this may sound like a good thing, quite often if you wear a brace while using a computer, you will end up using other muscles in a strenuous way to do the same work, and can cause other injuries because of this.

There is no such thing as an ideal wrist brace, it really depends on what they are trying to do.

In the course of your RSI journey you way well encounter many different styles of wrist braces.

My general rules concerning wrist braces are -

1. You shouldn’t jump in and buy a wrist brace without first seeking advice from a physiotherapist or doctor.
2. Ideally, it should be used to rest (heal) the wrist and the overused (painful) muscles that drive the wrist extension and flexion, and not worn when using a keyboard or mouse.
3. Exceptions to the rule are perhaps specific braces intended to stop excessive flexion of the wrist if you are prone to this. It’s a far better idea to be able to spot this flexion yourself and change it, but if you have difficulty doing this then a brace may be required. Alternatively have someone stand and watch over you with a big stick, you will learn faster then!
4. Braces used to rest the wrist should not be too tight, just a snug fit. Over tightening can lead to restricted blood flow to the hand and wrists.
5. Consider wearing a wrist brace at night in bed to avoid sleeping with your arms/wrists/hands in bent positions. It is critical that you don’t have a tight brace when doing this so as not to restrict blood flow.
6. Don’t use them unless you have to. Its better to know your pain, when it happens and try to make adjustments to your  work practice etc to reduce the causes than it is to just ‘bandage up’ your injured wrists into a brace.
7. Neoprene braces can be hot, sweaty, smelly and itchy to wear even for short periods of time. Better to look for ventilated elastic material ones.
8. Wrist braces are not a good  universal fit for everyone, so you may have to make some adjustments to it to make it comfortable, including cutting bits out of it or adding some customised padding.
9. Wear them at work and they do flag to your employer and colleagues that you have a RSI problem!

Remember though, wrist braces are not a solution to RSI, they are really only there to rest an injury and ease pain. To address your injury it is far better to try to make adjustments to your work to stop the motion that is causing you to have the pain. In other words, you should monitor your wrist, hand motions at a keyboard etc, and make adjustments to your bad working practices, including posture changes. You should also introduce more regular breaks away from your computer along with a good stretching routine and some physical activity.

The RSI pain cycle once ‘locked’ into is a hard one to break free from. The common mistake is to address only one or two factors. If the sufferer is at an early stage of RSI, and is fortunate then one change eg ergonomic setup may be enough to break free, but any medium/long term sufferer who is trapped in this cycle should consider addressing most/all of the underlying trigger causes to allow the transition to an RSI free life. The second diagram (click image to enlarge) shows the key areas to address to break the cycle.

It’s happening (quite badly) on the middle finger of my right hand – so much so that I have to use my other hand to prise the stuck finger open again! I also have minor trigger symptoms on some of my other fingers. It’s not just an inconvenient condition, it can be quite painful too! Usually trigger finger cases can clear up with some rest, ice and anti-inflammatory medication but this one has been with me for quite some time.

The trigger condition has been diagnosed as such by doctors, and has been treated twice with steroidal injections (to no avail). Surgery looks like the next option for me to relieve this condition, and is only a day patient procedure done under a local anaesthetic. I am however waiting for summer to pass before going ahead with the surgery, although going through with it will mean me taking 1-2 weeks off work to allow it to heal. This would be fine if I was employed with entitlement to sick pay, but being self employed means two weeks without pay! Not fair is it?

Interestingly enough this is a condition that I can remember happening mildly when I was younger (maybe as young as 12), where the middle finger of both hands would lock and click when I forced them open. These symptoms were not much of a problem to me back then, and they ceased completely when I reached my late teens.

However, the condition has over the last 10 years returned, and in the last 5 years has got much worse. The consultant that I have seen asked me what it is that I grip tightly, but I’m not aware of any one task I do with excessive gripping. It’s apparently a common symptom of over-gripping power tools or bicycle handlebars etc.

I personally feel like it has flared up due to the other RSI symptoms I have. The tendons in my arms, wrists, hands and fingers have taken some amount of abuse from computers over the years.

According to one summation from RSI Relief -

“Most clinicians believe that the disorder is caused by the tendon sheath because it becomes thickened or swollen and pinches the tendon and prevents it from gliding smoothly. But common sense reveals that the history of patients suffering with Trigger Finger have one common denominator, overuse, excessive use and/or abuse of the hands from work and recreational activities.”

The only ‘abuse’ I can think of over my history is keyboard and mouse related. Other than a bit of cycling, kayaking etc I have rarely abused my hands in any other way, and certainly am not aware of any excessive gripping.

To me it is one more aspect to my life dealing with a long term RSI condition(s).

It should also be noted that video gaming is a highly addictive pastime (I speak from the experience of my youth). Video games are designed to be addictive; let’s face it, if they were not, players would rapidly lose interest and move onto something else, and the manufacturers would not sell many games.

There are usually very high levels of repetitive motion involved to complete a game stage and there are usually many levels to  complete, which allow the individual to achieve the elevated status of finishing that level (quite often against the clock) and progress to the next with a sense of achievement. There is a high degree of addiction involved in this process which can involve spending literally many hours in a sedentary position whilst making very repetitive motions with your arms, hands and possibly feet while using keyboards, mice, joysticks and other types of controllers.

In the specific case described in the article, a girl came down with a bad skin condition involving sore lumps in her hands and feet after playing for hours on a gaming machine. In a quote from the article that refers to a Swiss doctors’ report it states that,

“Excessive video gaming is currently regarded as an alarming health issue… Recently, organic pathologies such as acute tendinitis, called Wiiitis, or video game-induced knuckle pads have been added to the list of video game-related pathologies. We report… ’PlayStation palmar hidradenitis’ as a cutaneous (skin) pathology induced by console gaming.”

They also recommended that,

“If you’re worried about soreness in your hands when playing a games console, it might be sensible to give your hands a break from time to time and don’t play excessively if your hands are prone to sweating.”

It’s easy to make these recommendations but try telling that to an addicted game player when they are close to achieving that ‘next level’. The medical community does not currently appear to address the addictive nature of computer gaming as well as the resulting conditions. To be honest, I can’t see any way to control this other than extensive education or (more radically) forcing developers to programme in rest breaks to gaming software itself, maybe between levels (you can just see that happening!).

My guess is we will continue to see more and more of these types of injuries and more and more of them will be happening to children who still have a large portion of their computer intensive lives ahead of them. I think that the only way to truly address the problem is to educate parents about the dangers of such gaming systems and their potential for causing repetitive strain type injuries. However, its not just children who are at risk. How many grown adults spend their ‘away from work’ time playing 3-4 hours of video games a night? I’d say a fairly large percentage of the (mainly male) 15-30+ age group.
