The user friendly HandShoe Mouse is an ergonomic mouse available in 3 standard sizes: Small, Medium and Large. Wired or Wireless.
To maximize the advantages of the HandShoe mouse and experience maximum comfort, a correct fit is essential. It is imperative that you measure your hand. (See example picture).
The distance from your wrist (the cross over between hand and arm) up to the tip of your ring finger. This length provides an indication of the required size.
SMALL: 6.1" - 6.9"
MEDIUM: 6.9" - 7.7"
LARGE: 7.7" - 8.5"
The HandShoe Mouse is plug and play; no special software drivers for Mac or PC are needed. Controls consist of 2 buttons at an ergonomic position and a scroll wheel fitted with a switch mechanism.
The large size HandShoe Mouse has a third mouse button. This mouse button is not programmable; it has the same function as the click function underneath the scroll wheel.
HandShoe Mouse: Ergonomic Mouse Backed By Ergonomic Research
In the past decade, the use of computers has exploded and today you'll find computers in every company or organization and in a fast growing percentage for private use at home. Today it has also become clear from dedicated research, that almost one in six office workers are suffering from Musculoskeletal Disorders (MSD), including Repetitive Strain Injury(RSI) and Carpal Tunnel Syndrome.
Research has proven that a lot of these complaints are related to the use of a conventional, standard computer mouse.
The Erasmus University Medical Center in the Netherlands has clearly identified these problems and has also spent several years to design and test in the field, the best and most comfortable ergonomic mouse.
Gripping and Pinching
Studies performed by the Medical Center of Erasmus University in the Netherlands, have shown that physical complaints, as a result of the extensive use of a conventional computer mouse, were often related to excessive 
gripping and pinching of the mouse. A standard computer mouse is simply too small for your hand, so you need to keep your hand and fingers in an unnatural gripping and pinching position to hold on to the mouse.
Gripping and pinching may result in tension in your deep neck muscles.(see image on the left)
This may lead to a reduction of the space between the first rib and the clavicular bone which could translate in pressure on nerves, arteries and veins and a restricted blood flow in your arms and hands.
Examples of complaints, caused by gripping and pinching are:
- head aches radiating from the neck area
- tingling feeling in arms and hands
- reduced mobility of the head
- loss of force in the hands
- obstruction of blood flow, numb feeling
Complaints may also increase as a result of stress.
Continuous Lifting of Fingers ("Hovering")
The Erasmus University studies have also shown that, when using a conventional computer mouse,you are obliged to almost continuously lift the fingers above the mouse to prevent inadvertent switching.
This may lead to over exertion of certain muscles (the extensor muscles) in your arms and hands. As a result of this exertion, excessive tension in the deep neck muscles may occur. When these muscles are tense they can virtually close the costoclavicular gate between the first rib and the clavicular bone.
Another aspect addressed by professor Van Zwieten of Hasselt University in Belgium is the highly intense use of fingers, for example with a conventional computer mouse. This may lead to hand- or finger complaints. To understand the finger positions concerned, we analyzed some of its joints by functional anatomical research.
It appears that the functional demand of a stabilized arch of the finger will be met, by designing and using a computer mouse that is pre-shaped to prevent disorders caused by intense use of the mouse.
In current e-learning practice, each student’s fingers, hand, and even whole upper extremity, may benefit from ergonomically safe working conditions, thus using the computer successfully.
A statically and dynamically stabilized finger arch as is enabled by the HandShoe Mouse is needed to prevent complaints. (ref: publication of professors K.J. van Zwieten, K.P.Schmidt et al, 2010)
Blood vessels and nerves that pass through this gate may be pinched and the blood circulation may thus be hampered (possibly also resulting in carpal tunnel syndrome).
Pronation of the forearm
When a (seated) person shifts his hand, palm downwards (fully pronated forearm), to and from his body, e.g. by moving a conventional computer mouse over a desk top, the Radius gradually crosses the Ulna. This is partially realized by contraction of the muscle Pronator Teres. Crossing of Radius over Ulna is defined as pronation of the forearm.
Such frequent movements could result in Repetitive Strain Injury complaints. (ref: publications Russian Scientific Practical Conference, Nov. 2008.
