Recent Harvard Study Confirms HandShoe Mouse Principles

During our field study to develop the HandShoe Mouse, we noticed that a non supported arm resulted in complaints in neck and shoulders (Trapezius muscle). The advice to support the arm and let the hand rest on the body of the HandShoe Mouse quickly resulted in a reduction of complaints.
Our team of Erasmus University Medical Centre reported the field study in the paper “Result of the use of a hand supporting computer mouse by patients with neck and shoulder complaints” (2006).
These results are confirmed in the paper by Prof. Han Ming Chen “The effect on forearm and shoulder muscle activity in using different slanted computer mice” (2007).

Through the years we have been addressing the negative effects of the use of for example keyboard trays. This in view of the excessive muscle loads incurred due to forearm and hand not being supported.

Effects of Forearm and Palm Support

Therefore we are pleased that the recent study by the Harvard School of Public Health “Effects of forearm and palm supports on the upper extremity during computer mouse use” (2013) confirms these earlier studies.

In line with the above,Arm op Bureau 1-met vink web it is interesting to know that the use of a slanted mouse like the HandShoe Mouse prevents the possible negative effect of support of a forearm on a hard surface like a desktop. Of course a good alternative to provide the necessary support are chairs with armrests.

Desktops with sufficient space provide the significant advantage that one is free to move.

This contrary to arrangements which inhibit free movement and force a person in a rigid position without enough space to work e.g. put down papers etc.

In line with the above mentioned publications forearm and hand support are a prerequisite for a comfortable working position and to prevent unnecessary loads in Trapezius and deep neck muscles.

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.

Ergonomic Mouse Research Shows Need For Hand Support

Claims of creating one of the most ergonomic computer mouse models ever, need to be backed up by hard facts and research.
Thankfully the HandShoe Mouse has been created based on studies designed to discover the most appropriate way to support the user`s hand while they are interacting with their PC via a pointing device.

The research was conducted by professionals at the Erasmus University Medical Centre, which is based in the Netherlands. It was arranged to help address the common issues associated with regular computer mouse use, such as repetitive strain injuries (RSI’s) and carpal tunnel syndrome, both of which can threaten anyone who spends all day in front of their PC or laptop.

Various tests and experiments carried out over a period of several years have led to the arrival of the HandShoe Mouse. But first it was necessary to establish what causes the problems when using standard mouse models.

The first thing that researchers found was that the size of a computer mouse is usually not adequate to provide your hand with a comfortable platform for computer use. This means that most people end up pinching or gripping the device, which not only impacts your hands and arms but can also lead to tension in your deep neck muscles and pressure on arteries and nerves within your torso.

Reduced blood flow, less head mobility and even headaches can be caused by this, all of which can be compounded by the stress of everyday life and work.

Researchers also found that when using a standard mouse, most people keep one or two fingers constantly hovering over the buttons as a result of the need to avoid making an accidental interaction which could result in unintended onscreen inputs.

A similar study conducted at Belgium`s Hasselt University looked at the way that constant finger use in standard mouse models can do damage. This is where carpal tunnel syndrome can emerge, since pinched nerves and veins will reduce circulation and cause a gradual deterioration in the area.

The HandShoe Mouse was created after the analysis of data relating to the joints within the hand. It has an exterior shape that helps to keep fingers supported, eliminates the need for constant hovering and allows you to use the device as often as is necessary without encountering issues further down the line.

HandShoe Mouse Hand Support Counteracts Standard Mouse Use

The team at Hasselt University looked into the way that the user`s arm sits when using a standard mouse, describing it as the neutral handshake position. It was discovered that this puts particular pressure on the membrane connecting the two bones that make up the lower arm, with this tension ultimately leading to yet more physical complaints.

All of these dilemmas that are faced when using a standard mouse can be counteracted thanks to the HandShoe Mouse.

Its slanted body means that the neutral handshake position is not automatically adopted, while the finger support and overall makeup of its body means that it is as ergonomically sound as possible based on the currently available research. You will be wishing that an Android tablet PC was as easy and comfortable to use for extended periods.
