"Just hands fall off! " - complains spent the day at the computer Manager. While scientists decide to classify whether the "carpal tunnel syndrome" to occupational diseases specialists, regular users are buying an ergonomic mouse pads and sounding the alarm in the medical blogs. Former chief editor of medical Internet site "Mednovosti" Alex Vodovozov a year ago became a left-handed: there were problems with wrist and right arm had to give "at the mercy" of the doctors. "Without surgery, but the treatment course lasted three months, including physiotherapy and exercise therapy, " recalls Alex. First time working at the computer with one hand, then decided to fix sore joints glove bowling - there is a steel plate just above the wrist goes. Now the worst is over, but his hands still sometimes "acting up" when you exceed a certain limit load".
Ten years ago on problems with wrists complained mostly professional musicians and drivers with experience. Today they were joined by programmers, web designers, system administrators, players and managers who conduct most of their work time on the computer.
Wrist pinned to the table, palm - mouse, fingers clocks do barely noticeable to the eye monotonous movement - right click, left click, scroll... Familiar? This is a direct way to carpal tunnel syndrome (PCs). He is carpal tunnel syndrome, in which people have dubbed the "rat bite".
Carpal tunnel syndrome is better to prevent than to treat. Because the case could end up operation. Meanwhile, there are simple ways to prevent it.
Simple movement
To recognize "mouse bite" simple. If all of a sudden starts to hurt right hand in the place where you would normally feel the pulse. If in the morning, get numb and not sell three finger: the middle, thumb and index finger. If your wrist swells, the fortune-teller don't go - this is it!
First, the discomfort expressed weakly, so people may long to write them on a trivial injury or sprain. Feeling that with the right brush that something is wrong, the Manager thinks: "I guess last weekend was damaged ligament, when played Golf on the championship of the company". But the pain does not abate, but only intensified. Then blame not the Golf club, and mouse for your computer.
To understand what happens to the patient by the hand of a worker office, imagine that we looked inside of his wrist. Here we have the gutter, with three sides bounded bones, but the fourth - wide transverse ligament. She, like elastic cuff that covers the carpal canal-side flexion of the surface. Inside this tunnel is the median nerve and tendons of the muscles of the hand.
In patients with "mouse bite" link cuff thickened, and, therefore, the carpal canal is narrowed and passing it the nerve davlen. Hence the numbness of fingers. In terms of total distress suffer and tendons, which by their nature substantially more mobile than the nerve. They RUB against each other, inflamed and painful. Such is the sad result of a computational load on the hands.
And to blame respected managers and web designers, but themselves and their work, nobody. Western doctors so that patients did not doubt the cause of his ailment, and even invented the "talking" term RSI (repetitive strain injury) - "chronic injury from repetitive strain". Himself Berger Pascarelli, a renowned expert on RSI from Columbia University (USA), I am sure that this syndrome can be considered as an industrial injury.
Although not all so sad. Because not everybody who has a day sitting at the computer, start to hurt hands. A healthy body is no mouse is not terrible. And need something to nothing: the normal metabolic and hormonal background, perfect joints and the absence of a genetic predisposition to their damage. Other advanced users, who are in the risk group, the worth of oneself and just in case from time to time to check how are things with your wrists?
Usually the diagnosis of carpal tunnel syndrome involved a neurologist, but if you want it you can do yourself. Enough with all his strength to squeeze the hand in a fist or put them together, as do positive heroes in Indian movies. If after two minutes the fingers start to numb, then threats to rest there. To be sure is to measure blood pressure. The figures here do not matter, the main thing is that the palm iriatai hands ran down my spine.
If you still numb and ran, even in the presence of a whole bunch of symptoms, delayed. Urgently to the doctor. And not a neurologist, which is recommended on medical forums such as Amateurs, and a specialist in hand surgery. Don't worry, no you immediately cut will not. First, the doctor will assess the damage to the brush, and then offer the most optimal treatment tactics. Keep in mind that after surgery relief occurs within a few days, and drugs - in a few months.
On his hands?
Prior to the first typewriters patient with carpal tunnel syndrome in medical practice were considered exotic, something like a bearded woman. But for a long time to beat on the keys with impunity failed. Just a few years later the doctors started talking about PCs as... "syndrome typist".
If we compare the number was professional Nordic texts and then how many computer users now, it is understandable why doctors are sounding the alarm. It is only in the last ten years, the number of patients "mouse bite" has increased considerably. For example, in France in 1996, the surgeons did on the carpal joint, one or two operations per week, and in 2006 - more than twenty. Does anyone seriously believes that the statistics jumped at the expense of the milkmaids or musicians?
I would not want to exaggerate, but, according to Western experts, the situation will deteriorate further. And according to our "epidemic" RSI sweeping computerised America and the EU, have already spread to Ukraine.
As the saying goes, there are two news - good and bad. Let's start with the good. We don't have to reinvent the wheel, based on the experience of foreign colleagues: in 1999, a respected national publication dedicated computers, walked out of the crisis. Namely, prevention and prevention. Arranged according to the laws of ergonomics workplace, reducing the hours spent at the computer, and timely call for help. By the way, all together will be much cheaper than treatment of already formed sacs.
Well now for the bad news. The majority of Ukrainian careerists are workaholics, and most of them are afraid of doctors. Such computer will sit on to victory and to the bitter to endure. Moreover, even in large IT companies have staff specialist in ergonomics. Its functions in the best case somehow divided between the chief of administrative part, which is responsible for the purchase of computer equipment, and the Manager on work with the personnel. And, despite the fact that the equipment is purchased the latest (from the point of view of performance), staff cost without keyboards, mice and mouse mats that reduces the load on the wrist. Needless to say, the situation in the smaller and far from computer technology companies? What ergonomics? Replaced the CRT monitor to LCD - and okay!
The light at the end of the tunnel
The rescue of drowning - the handiwork of drowning. If management sees no need to care about the wrists subordinates, they must do it themselves. Fortunately, manufacturers of computers is not lazy - but this year, given the market with more reliable means of protection against CPS.
Gentleman's set a seasoned geek:
- mouse pad with gel cushion that reduces pressure on the wrist;
correct computer mouse: first, without the "tail", and secondly, allowing the brush to maintain the physiological status;
- ergonomic keyboard, for example, broken in half for each hand has its own half, or "roach" in which the right and left side meet at an angle and provided support under the wrist.
All of the above today, almost a classic, but there are delights. American specialist in hand surgery mark Eberbach has developed special gloves for working at the computer. They are fingerless, but with two soft pads on the wrists, anatomically located on both sides of the median nerve. Not to sdavlivaya. Another us invention springy keyboard. Presumably this should reduce the load on the wrist when it is printed.
Last mousey squeak:
- mouse standing column;
- mouse lying on its side;
- mouse, zu-shaped curved - if you take it in your hand, the feeling that you hold the gun.
Against this background, the novelty of Artemy Lebedev - manipulator arrow - looks, to put it mildly faded. In addition, she and a special ergonomic no different.
The cost of any of the clever mice approximately one and a half thousand rubles.
For example, to advance far. No problem - you can use absolutely free way to prevent chronic injury from repetitive strain" - erg-aerobics. The name of the beautiful, and in fact exercises for hands, but not simple, and developed by members of the American Association of physiotherapy. Slowly squeeze the hand in a fist, slowly release. Press the palms on the inside of the lid of the Desk. Bend back my fingers. Each time the voltage is held for ten seconds, every exercise is performed ten times in one sitting. Number of visits - how many are not lazy.
Not so long ago it is already known to the victims RSI was joined by another rather large group of citizens - owners of cell phones that are too often trying to enter SMS-messages. But their problems, I'll leave the conscience of the mobile operators.
