First True Ergonomic Computer Mouse (The HandShoeMouse) Enters US Market
Finally, a true ergonomic computer mouse, designed by a Dutch medical university and field tested for almost two years has now entered the US market. The proven and patented design of the HandShoeMouse has a special shape which gives your hand a rest instead of repetitive strain.
The HandShoeMouse (www.handshoemouse.com) prevents pinching and gripping, a major cause of Repetitive Strain Injury (RSI) and Neck, Shoulder, Arms and Hands complaints, due to the shape of a traditional computer mouse. The HandShoeMouse, challenging every mouse on the market, is going to make a difference for an estimated 25% of the total work force in the USA which may be suffering from RSI symptoms.
(PRWEB) November 11, 2009 -- A growing number of the worldwide workforce using computers is suffering from pain caused by intensive use of a traditional or even an ergonomic computer mouse.
A recent study across 23 European countries (Fit for Work Europe) has shown that over 40 million (almost one in six) members of the European Union workforce are affected by Musculoskeletal Disorders attributable to their work (MSDs – conditions affecting bones, joints and connective tissue).
Repetitive strain injury is a major part of MSDs and is mostly related to intensive use of a computer mouse. In the Netherlands 30% of female workers and 23% of male workers are suffering from RSI costing the Dutch economy billions of dollars every year.
Assuming a similar percentage of the work force in the USA will be affected by mouse related RSI-complaints it is estimated that the US economy is losing hundreds of billions of dollars a year due to RSI.
Typical Symptoms
Forceful gripping or pinching, next to hovering of the hand and fingers above mouse and buttons has been identified as a major cause for several physical complaints in neck, shoulders, arms and hands.
Moreover, gripping and pinching may result in tension in the deep neck muscles. This may lead to a reduction of the space between first rib and clavicular bone which could even translate into pressure on nerves and a restricted blood flow in arms and hands.
Examples of complaints are:
| | - headaches 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

The mouse re-invented
A team of medical and ergonomic specialists from Erasmus University Medical Centre in the Netherlands used electromyogram (EMG) measurements to show the muscle activity of hand and fingers when using a mouse. They found that relaxation in neck, shoulders, arms and hands can be realized by means of a reduction of force when handling a mouse.
Furthermore the researchers defined 7 physical load types causing excessive muscle forces resulting in pain when using a mouse. This includes lifting of the fingers and or the whole hand. Pain can also be caused by forcing the hand in a flat or a handshake (vertical) position when using a mouse.
Evaluating a traditional mouse and 8 ergonomic mice on the market they found that all of them were still causing complaints due to physical load factors which were confirmed by the EMG measurements.
Having decided to re-invent the mouse, the research led to a new patented design showing the least of muscle activity on the EMG measurements as compared to all mice investigated. The HandShoeMouse appeared to have the perfect angle of the hand when resting on the mouse.
