Ergonomic mouse review of DXT02W Vertical Wireless Mouse

Ergonomic vertical mouse for mouse elbow - tennis elbow - golfers elbow - computer RSI

Revised: Dec 2018

Computer Posture welcome a guest post by Stephen Bowden a leading ergonomist who explains the design aspects of the DXT02W. This design is quite different to other vertical mice and important reading for computer users before our Product Review

This mouse is what Computer Posture regard as the best ergonomic mouse out there! Those who’ve seen BBC One “Breakfast”, may have noticed anchor-woman Naga Munchetty using a DXT02W.

What is the problem with a normal mouse?

fiddler crab...early form of mouse RSI?The danger for most people who use a mouse/touchpad is from the twisted arm posture that is maintained often for extended periods of time. This posture often involves reaching out to some extent which exhausts particular tendons in your arm from shoulder to fingertips and distorts your body’s core stability around the upper back and chest with some muscles underused and wasting and others overused and exhausted.

We are becoming not unlike fiddler crabs in having unbalanced limbs and we tend to pay for this with tendonitis and other RS I conditions!


DXT02W Ergonomic Vertical Wireless Mouse

The importance of precision

Comfort, accuracy and productivity are some of the most important aspects of an ergonomic mouse design that users look for.

To create an ergonomic mouse with the highest degree of performance, the design should consider the difference between the limbs segments (hand, wrist, elbow & shoulder) in terms of their form, function and performance.

The work of Zhia (Zhia, Milgrim, Buxton, 1996) has shown that effectively designed computer mice that rely on all parts of the arm to work in synergy, with each limb segment performing the functions it does best, can outperform computer mice that rely solely on limb segments such as the shoulder.

The small muscles and joints in the fingers have greater information processing abilities for movement and sensation that other body parts such as the shoulder. The large muscle groups that operate the shoulder and elbow are adapted for power and large gross movements. The smaller muscle groups that operate the fingers and thumb have greater agility.

Adopting the precision grip (Napier, 1956) where the index finger and thumb work closely together (not by moving the whole arm from the shoulder) allows for accurate productive cursor control.

By eliminating or restricting movements of the fingers and hand you are forced to use the elbow and shoulder to move the mouse. This does not make sense, as the shoulder and neck are the most common areas of discomfort within office workers.

Many large ergonomic mice feel the whole hand and fix it in one position which pushes cursor control to the shoulder which we know is not designed for accurate movements of a cursor.

DXT02W ergonomic vertical wireless mouseThe DXT Mouse allows the hand to move and operate the cursor with greater precision than mice that force shoulder only movements. The DXT is like an extension of your fingertips which is why it has been shown to more accurate than other large whole handed computer mice.

How to achieve comfort

A mouse that supports the hand and wrist in the position of function/rest results in less muscle tension while allow accurate cursor movements. Have a look at your hand when it’s by your side in a relaxed state this is the position of function/rest where there is the least amount of tension within your hand.

By adopting this posture when using your mouse you will allow the hand to move and work in synergy with the rest of the arm to ensure natural movement which will help improve comfort.


Review summary by ComputerPosture

The DXT02W is a vertical mouse but with a very different design to the norm. We weren’t sure how this would feel but gave it a few days use and we are incredibly impressed. The overall feel is closer to how you hold a pen than the feel of a conventional or most vertical/ergonomic mice.

The DXT mouse doesn’t rely on shoulder movement which is unique. Even good vertical mice, such as Evoluent, who address the arm twisting problem of conventional mice still don’t address the shoulder tension one. So this is a big plus!

Precision is excellent. The perfect choice for fine detail work such as CAD / illustration / graphic design. The DXT mouse uses the natural pinching posture of thumb and forefinger and so delivers the great natural dexterity and nerve control that we have in our fingers.

The small footprint and ambidextrous design is great. Small hands will find this mouse a real winner against the other options…as will large hands!

Any wireless mouse needs to go into standby quickly after movement to conserve battery power but too quick can be annoying. The DXT mouse seems to have got that balance right.

DXT02W-ergonomic-vertical-wireless-mouseInitially more tension than expected was felt in the forearm flexor tendons. This may not be the best mouse if you are currently suffering from carpal tunnel tendonitis issues although should be fine after recovery. Shoulder tension was felt to be much less than usual and so likely to be better for frozen shoulder, tennis elbow and cervical osteoarthritis sufferers.

Our Conclusion

The best mouse out there! It has a different design to Evoluent and if you are already suffering from RSI, your specific RSI condition may favour one over the other. The DXT and Evoluent mice however are the best ergonomic mice available and our favourites.

Popularity has made the wireless DXT02W mouse scarce; if it isn’t available, the DXT02 wired Ergonomic Mouse is the next best as long as you ensure the wire runs freely and doesn’t drag the mouse backwards on the desk.
