The syndrome of the carpal channel is often joined to use prolonged of the keyboard of the computer. However, according to a new survey, not only the keyboard would not be guilty, but it would even offer a protection against this syndrome that affects the median nerve of the hand.

among those that used the computer during more of four hours per day, 2,6% presented a syndrome of the carpal channel, compared to 2,9% for those that there passed one at four o’clock. This proportion was of 4,9% at the people whose use limited itself to one hour or less and it climbed to 5,2% at those that didn’t use the computer at all.

According to one authors of the survey, the Dr Islam Atrophic, to hit on a keyboard would decrease the risk of swelling and therefore of pressure on the median nerve of the hand. If he/it is however true that the apparition of this syndrome can be bound to work, the use of the computer is not to the number of the factors of risks, it specifies. The activities the more to risk would be rather those that ask for a torsion repeated of the wrist and a certain strength of the hand.

However, a bad positioning of the hand and the wrist on the keyboard, for example if the wrist is in bending or in extension extremes, can make increase the risk to endure the carpal channel, underline the Dr Atrophic.

And the mouse? " We don’t have any proofs currently that would confirm that the mouse is part of the factors of risks, but it is necessary to say that little study bent on its use", he/it specifies.
