The End of Keyboard Trays and Mouse Platforms?

By: Drs. ing. Paul C. Helder

I think we all enjoyed the innovations presented during this year’s Ergo Expo in Las Vegas.

Of course various new innovative products were presented next to already well known products which are from the outset near to the optimal solution. These can therefore hardly be improved, because they have been developed based on medical research, like for example the HandShoe Mouse by Hippus.

A very obvious difference with previous shows was, as far as I have noted, the absence of keyboard trays with mouse platforms. Apparently the industry has seen the light.
Instead we now see a multitude of height adjustable desks.
These desks not only provides sufficient space to work, but, far more important, they allow you to support the forearm and thereby relax the Trapezius – and Deep Neck muscles.

Already in 2006, Professor Han Ming Chen addressed this point in his paper: The effect on forearm and shoulder muscle activity in using different slanted computer mice, published in Clinical Biomechanics.

Height Adjustable Desks: Free Movement

We are not robots, we should allow ourselves freedom of movement.
Also paperwork can now be readily available on the desk. And there is also plenty of room for your HandShoe Mouse!

The adjustable desk takes away the restriction of the cramped space dictated by the concept of the keyboard tray. Long and behold, we now even see micro desks to further increase the available desk space.

I hope that based on anatomical and bio-mechanical research the ergonomics industry will realize that concepts from the past do not always comply with the best solution. The keyboard tray was a perceived good alternative. However, everybody realized that restrictions prevailed. The adjustable desk and chair now provide a fitting solution based on fundamental scientific research.

 

Why The HandShoe Mouse Has No Thumb Buttons

Many times we have been asked why the HandShoe Mouse does not have switch buttons under the thumb.

Well, there is a reason: the thumb is restricted in its motion possibilities. Repetitive thumb motions to activate such buttons could thus lead to inflammation. We have therefore decided not to incorporate any thumb buttons in the truly ergonomic HandShoe Mouse.

Do You Suffer From “Gamers Thumb”?

An already well known discomfort as a result of unnatural motions required to operate thumb buttons is the so called gamers thumb or SMS thumb.
Various studies have shown that repetitive motions of the thumb may lead to irritation.
Muscles control tendons which slide backwards and forwards through a tunnel.
To allow these tendons to move without friction the human body produces a slippery substance.

Inflammation

Excessive gripping and pinching, required to control these thumb buttons, may cause inflammation.
As a result this slippery substance deteriorates, and gets watery. The smooth sliding action of the tendons is then hampered.

This will cause pain, tenderness, swelling over the thumb side of the wrist and difficulty gripping.

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!
