The DXT Ergonomic Mouse 2 from City Ergonomics is a fingertip vertical mouse designed to enable the hand and wrist to adopt a relaxed vertical posture. Control of the mouse is achieved by using the small muscles and joints of the fingers as opposed to the larger muscle groups of the shoulder and arm. Since the fingertips provide much greater precision than the arm, this makes the DXT mouse suitable for those seeking precision and fine control. The DXT Ergonomic Mouse 2 features light click buttons to minimize the effort required for clicking. The unique ambidextrous design enables individuals to easily balance the workload between the left and right hands.
The DXT Ergonomic Mouse 2 moves with minimal resistance, requiring nominal effort to accomplish effective cursor control. The weighted zinc base provides vertical stability and enhanced tactile feedback. There are four DPI (dots per inch) settings, further enhancing the sensitivity and increasing accuracy when performing fine cursor movements. This also permits individuals to have greater control over the speed of the cursor when performing tasks requiring varying degrees of control. The DXT Mouse 2 is also available in a convenient wireless version.
Those with larger hands may wish to consider the DXT Mouse 3 models (wired or wireless). The DXT Sizing Chart can be used to determine whether a DXT 2 or DXT 3 mouse is more suitable.
Eliminates Static Grip Force - When using the DXT Ergonomic Mouse individuals are able to lightly hold the mouse between the fingers and thumb. In fact, movement is actually easier to perform when less pressure is applied. This encourages them to greatly reduce the level of force being exerted while "gripping" the mouse. Learn More about Static Grip Force When Using the Mouse.
Encourages Load Balancing - The convenient ambidextrous design of the DXT Ergonomic Mouse means that it is possible to easily switch between left and right-handed use throughout the day. This can be beneficial both in avoiding potential RSI-producing overuse by one hand and arm as well as a means to accommodate graduated usage increase during rehabilitative therapy.
Reduces Pronation - The pen-like orientation of the DXT Ergonomic Mouse 2 rotates the forearm out of the pronated position required by standard mousing devices. This can reduce the risk of developing pronation-related issues such as Tennis Elbow. It also eliminates much of the Wrist Extension facec when using a traditonal "palm down" mouse. Learn More About Pronation.
Reduces Risk of RSI in Shoulder - The design and usage of the DXT Ergonomic Mouse significantly reduces the amount of movement required from the shoulder, especially the "overreach" which is common when using a traditional full-size keyboard and mouse.

Ambidextrous Design: The symmetrical design of the DXT allows use by either the right or left hand. This feature means that the DXT Ergonomic Mouse can be used to aid in recovery from or to potentially prevent upper limb disorders.
Compact Ergonomic Design: Although compact in design, the DXT Ergonomic Mouse works well for a broad range of hand sizes. Since it is held primarily through the fingertips and controlled by the fingers, even those with larger hands are able to achieve effective control without facing the task of trying to "grip" a mouse which is too small. The more "pen-like" movement is natural to most, requiring minimal adjustment to the method of movement. The compact size and minimal degree of movement required makes the DXT well-suited to mobile usage or deployment where limited space is available.
Precision Grip Design: The DXT Mouse 2 has an optimum fingertip grip. The shape and size of the DXT are what permits the thumb and fingers to work together to facilitate higher accuracy and performance. The DXT takes advantage of the higher sensory input afforded by fingertips and thumbs, input that traditional palm based mouse designs cannot provide.
4 DPI Settings: Selectable resolution of 500/1000/1500/2000 dots per inch. The selectable resolution allows one to quickly change the cursor speed to allow for different tasks and increased accuracy.
USB Connection Plug and Play: No software to install.
Light Click Buttons: The DXT Ergonomic Mouse 2 features Light Click Buttons to reduce the effort required to perform Left and Right click functions

Hold the DXT Ergonomic Mouse lightly between the thumb and fingers. Employing a high degree of pressure will actually limit the amount of control you have over the mouse, leading to a desire to exert even more pressure in an effort to achieve the desired result. This results in an unhealthy amount of "static grip force" and will also leave you frustrated with the mouse. A light touch on the mouse will permit the thumb and fingers to move the mouse easily to achieve fine levels of control but it may take time to train yourself away from the old habits of gripping a mouse more firmly. If you find that your hand is hurting or that you are unable to achieve fine control you may well need to relax your hand.
Load Balance your usage throughout the day by regularly switching between right and left hands. Not only does this reduce the load borne by a single hand, it can also stimulate the brain as the non-dominant hand learns to accomplish movement that until now may not have been required of it.
Consider switching to a Compact Keyboard. If you do not require the numeric keypad or can train yourself to utilize the "upper rank" numeric keys you should consider a compact keyboard which can reduce the reaching to the mouse. The design of the DXT Mouse already addresses this to a degree but eliminating additional unnecessary reach is always worth considering.
Take Regular Breaks, especially in the learning stages. Overworking any part of the body can result in RSI but because computer use puts an exceptionally high load demand on the hands they are more susceptible to this overuse. Load Balancing is one way of addressing this but not all users will be able to achieve sufficient control with both hands. Anytime you begin to experience discomfort you should either consider a hand changeover (if it is possible) or take a break and perform some other work or even do some hand stretches and flexing.
