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.
