Causes of Mouse Pain

When we think of pain, we think of broken bones and the muscle pains of professional athletes. We also think of people who do hard physical work. In this age of technology, however, there are many others suffering from severe pain.

Hand and Wrist Complaints

More and more computer users are suffering from hand and wrist complaints caused by extensive use of a regular computer mouse. Research into this issue was done by Erasmus University in the Netherlands who identified a number of key causes of these complaints. One example is gripping and pinching of a regular mouse, while holding it but a standard mouse is often too small for the hand. This can cause tension and pain as far away as the shoulder and neck.

Mouse Pain From Hovering

Another common cause is what we call hovering, when a person’s fingers hover above the mouse buttons to prevent inadvertent clicking. This creates tension on finger and arm muscles, which can again cause pain all the way up to the neck. Lastly, a vertical mouse forces the hand in an upright position, the two major bones in the arm are then parallel to one another. This causes serious muscle strain and may lead to RSI.

Stabilization of Hand Required for High Precision Tasks

During fundamental research and field research we noted the significance of a relaxed hand and forearm to operate a computer mouse. Gripping and pinching as well as reaching for the mouse showed to have severe negative effects on the upper extremity.

We require our hands to perform a great number of varying tasks with the mouse which requires high precision. Although Professor Van Zwieten, Department of Anatomy, BioMed, University of Hasselt mentions the possible risk of moving from the wrist in his paper “Hand Positions in scrolling, as related to PC-workers’ dystonia and treatment of dystonia by means of vibrostimulation and external shock waves therapy” (2009) we sometimes have to.

Higher precision requires stabilization of hand and forearm to minimize stress. It is from this perspective that we are pleased to be able to refer to the paper by Danuta Roman-Liu, et al. Department of Ergonomics, Central Institute for Labour Protection, Warsaw, Poland.

“Assessment of the musculoskeletal load of the trapezius and deltoid muscles during hand activity.” (2001). In this publication the following is mentioned:

First, higher precision of a task in which only the hand is involved, requires accuracy of movements which means more stabilization of the upper extremity and thus higher muscle tension. Furthermore, in view of the difficulty and possibly the complexity of the task a higher muscular tension can be expected.

No Effect on the Deltoid Muscle

Where is the Deltoid muscle?

The resulting muscle loads due to the performed task influences the tension of the trapezius muscle. Contrary to what is generally thought the study proves that there is no effect on the deltoid muscle.

It should be noted that the lower the level of force used, the more precise a difficult task can be executed. As a consequence, when the forearm is not supported, a higher tension of the descending part of the trapezius muscle results. We herewith refer to the paper by Professor Han Ming Chen of National Taiwan University “The effect on forearm and shoulder muscle activity in using different slanted computer mice” (2007) and our team of Erasmus University Medical Centre “Result of the use of a hand supporting computer mouse by patients with neck and shoulder complaints” (2006).

Support the forearm

So this publication proves the need to support the forearm when working with a computer mouse.

Ergonomic Mouse Prevents Pain

Mouse Pain?

Do you ever have tired or painful muscles in your hand, wrist or forearm after working with a computer mouse? The most common reason is that a conventional mouse forces the muscles in your forearm to continuous activity. You may end up with pain in your arm unless you take precautions.

In this video we will give you the technical explanation which is based on university research.
The anatomy of forearm and hand explains the sources of your complaints: hovering of your hand and fingers over the mouse requires action of the so called extensor digitorum muscle.
To hold onto your mouse another set of muscles is continuously active. You need the extensor carpi ulnaris to work from the wrist.

Best Ergonomic Mouse

In order to prevent the pains caused by a conventional computer mouse, we developed the best ergonomic solution:  the HandShoe Mouse. This mouse is taking all aspects into consideration. Now your muscles will stay relaxed as your hand is fully supported so there is no more hovering of your fingers. And you don’t have to grip it to move it. Last but not least, the support angle allows for easy movement from the wrist.

This video gives a clear view of the muscles in your arm and how they are affected when using a computer mouse:
