Carpal Tunnel Syndrome Explained

Carpal Tunnel Syndrome
Today, more and more people world wide realise that it is important to support your hand when using a computer mouse. If you’re using a mouse that doesn’t fully support your hand, you may eventually experience serious neural effects.

This short video explains why that happens: when you push your hand on the desk and force it in a gripping, claw-like position, your wrist is forced in an awkward, bent position. Tendons may become irritated and swollen.

Pins and Needles

This causes excessive pressure on the median nerve which controls your hand and fingers. First you will notice a feeling of “pins and needles” in the fingers, followed by loss of sensation and even a burning pain. This phenomenon is generally called carpal tunnel syndrome. The shape of the HandShoe Mouse provides full support of the hand and fingers to prevent this harmful pressure on the wrist. Please be aware that, even after providing relief from this pressure, the nerve stays tender and may still provoke pins and needles for weeks afterwards. But when you keep using this truly ergonomic mouse you should feel the difference!

What Causes Carpal Tunnel Syndrome?

In our ergonomic mouse research during the development of the HandShoe Mouse we noted a few significant sources of flow restriction in arm and hand.
On our main ergonomic mouse website we address this on the first page in the Research section.

A restricted blood flow to the arms could be caused by excessive gripping and pinching when you use a standard (not ergonomic) mouse. This may lead to a contraction of the deep neck muscles and thereby a closing of the Costoclavicular gate which is explained on the HandShoe Mouse Research page:

In line with this phenomenon is the complaint of Carpal Tunnel Syndrome.
One of the causes must be assumed to be a restriction of the lymphatic flow.
See the picture below, which shows the  lymphatic system as well as the main artery.
Some people believe you can prevent Carpal Tunnel Syndrome by means of excercises.

lymphatic flow

But it is not so much the exercises which could provide relief.
You have to tackle the source of the problem and one of the sources identified by our university based research is the Costoclavicular Gate.

The image presented here shows this gate and the artery. The lymphatic system is shown in black on the right.

The gate is affected by the space between the first rib and the clavicular bone.

Deep neck muscles

Deep neck muscle tension

Deep neck muscle tension will narrow this gate. The image on the left shows the deep neck muscles. In other words, it is the general tension in the deep neck muscles (more specific Scaleni) which is a major source of complaints which are generally referred to as Carpal Tunnel Syndrome.

It should be noted that by using the HandShoe Mouse you prevent excessive gripping and pinching. In general you should be aware that you do not grip excessively

This also applies to handling tools like screw drivers and hammers as well as cutlery, pencils, the steering wheel of your car etc.

Why You May Be Suffering From Repetitive Strain Injury

Today, many computer users are suffering from Repetitive Strain Injury or Carpal Tunnel Syndrome, due to the use of a traditional computer mouse or an inadequate ergonomic mouse.

Years of university based research has shown that a standard computer mouse is simply too small for your hand and is forcing your hand and fingers in an unnatural gripping and pinching position.
This may result in tension in your deep neck muscles, which will reduce the space between the first rib and the clavicular bone. This causes pressure on nerves, arteries and veins and a restricted blood flow in your arms and hands. 

Research has also shown that, when using a conventional computer mouse, you are almost continuously lifting your fingers above the mouse to prevent inadvertent clicking. This may lead to over exertion of the extensor muscles in your arms and hands and will also cause tension in the deep neck muscles and a reduced blood flow.

That’s why the special shape of the truly ergonomic HandShoe Mouse prevents gripping, pinching and hovering and  does reduce the risk for Repetitive Strain Inury and Carpal Tunnel Syndrome.
