The Rockstick2 Mouse retains all of the benefits and functionality of the original Rockstick Mouse but introduces a new design and added capabilities. As with the original Rockstick Mouse, the Rockstick2 addresses one of the most repetitive activities of computer use--generating mouse clicks. Rather than using one or two fingers to click a button, the user simply rocks the body of the mouse, tilting it slightly to the left or right to generate a click. The strenth of the entire hand can be used to generate the click, rather than the much more limited strength of the index or middle fingers. This makes the Rockstick Mouse2 a potentially good alternative for individuals with trigger finger or arthritis, or for anyone who has difficulty clicking the buttons on a conventional mouse.

The new design is also ambidextrous, enabling both left- and right-handed users to experience the benefits. The scroll wheel is located on the inside of the mouse, where it can be accessed easily by the thumb. This newest model also features variable DPI and a flange to keep the little finger clear of the worksurface. Two size options (Small/Medium and Large) are available.

The Pro Fit Ergo TB450 Trackball from Kensington offers thumb-operated cursor control that eliminates the traditional arm and hand movement required with a traditional mouse. The 45° angled body rotates the hand and forearm away from a prone position to reduce strain on the forearm. Cursor control is via the 34mm trackball which offers silky-smooth movement and adjustable optical tracking from 400-1600 DPI. The contoured body provides a support for the hand, naturally positioning the fingers over the right and left buttons. Vertical and horizontal scrolling function are provided by a tilting scroll wheel that features crisp detents, conveniently positioned between these buttons to complete the traditional mouse control layout. The index finger has easy access to convenient Back and Forward Buttons for browsing through multiple pages of a document or web page.

The Pro Fit Ergo TB450 Trackball offers Dual Connectivity that can simultaneously support connections to up to 3 computers or devices (1 via the included 2.4 GHz receiver and up to 2 more via Bluetooth LE).

As the Pro Fit Ergo TB450 Trackball places cursor control fully upon the thumb, (which on most other trackballs is generally shared by several fingers), anyone who has existing thumb issues would be advised to consider alternative solutions.

The Kensington Vertical Wireless Mouse angles the hand outwards towards a semi-vertical position in an effort to reduce pronation. A short flange keeps the side of the hand clear of the surface but still permits most of the little finger to make contact during movement. This wireless mouse is contoured specifically for right-handed use and operates plug-and-play. However, optional drivers are available for both Windows and Mac OS should one desire to customize the button functions. A convenient DPI switch accommodates quick access to five DPI settings (800, 1200, 1600, 2000, & 2400) to accommodate different work requirements. The wireless receiver has a 10 metre range and can be stored in the underside of the mouse to ensure it isn't misplaced. The traditional scroll wheel is clickable.

The size of this mouse means it is best suited for smaller or average sized hands. The body is narrower than most vertical mouse designs, which can lead to a tendency to want to "grip" the mouse which has the potential to lead to exerting unnecessary static grip force.
Note: While being identified by the manufacturer as a "vertical" mouse this angle is substantially less than most other "vertical" mousing products, the majority of which orient the hand well above 60° and therefore much closer to a truly vertical presentation.

IOGEAR's Phaser 3-in-1 Presenter / Mouse is an excellent tool for presentations at offices, libraries, and schools. The thumb-operated multi-directional trackball allows the unit to work as a fully functional mouse, as well as a remote presenter. The built-in laser pointer helps the user to direct the audience's attention appropriately. The batteries can be easily charged through the USB charging cradle. The versatile Phaser 3-1 can also transform to a desktop mouse. The contoured design allows for comfort and less fatigue while in use.

Created for those wanting an ambidextrous, wireless mouse with a more traditional look, this mouse offers a symmetrical design and a centrally located scroll wheel. Thumb indentations on both sides of the mouse provide a textured anti-slip surface. The mouse gives left- and right-handed individuals the option of distributing the workload by using the same mouse in either hand.

The Goldtouch Wireless Ambidextrous Mouse has a 1000 dpi optical sensor, and is powered by one or two AA batteries. (Note: Estimated battery life is two months with one battery, and four months with two batteries.) A wireless USB 2.4 Ghz mini receiver is included.

Caution: Those with larger hands may find this mouse too small for all but occasional use.

The Penclic Mouse from Penclic is an elegant precision mouse using a 'pen-shaft' design to make moving your cursor as easy as writing with a pen. Mouse buttons are on the pen-shaft for quick access, while there is a scroll wheel on the base. Available in wireless or corded models.

The Penclic Mouse (3rd Generation) provides an effortless and intuitive way to move the cursor with fine precision by employing motions similar to those used when writing with a pen. The pen can freely pivot in a recessed circular depression (ball/socket joint) on the base, allowing the user to find the best angle and orientation of the pen to maximize comfort and precision. The base itself glides to provide mouse control, and the movement of the base is achieved by using the small muscles and joints of the fingers as opposed to the larger muscle groups of the shoulder and arm. As the orientation can accommodate a wide range of positions, the user is able to move the mouse with either fine or gross movements (and accompanying positions) which can help to reduce any one set of repetitive movements. The design of the Penclic Mouse (3rd Generation) is also ambidextrous, enabling the user to easily balance the workload between the left and right hands. A number of improvements were made on this latest Penclic such as moving the scroll wheel onto the pen for easier access and better control. The buttons have also been simplified and are more intuitive and easy to use.

The MX Vertical Advanced Ergonomic Mouse from Logitech is their first attempt at offering a mouse which more aggressively reduces pronation than other mice in their line. The body of the MX Vertical is angled at a fixed 57° to reduce the risks associated with pronation of the forearm. The angled body is designed to provide the support necessary for the hand to "relax" while engaged with the mouse. However, those with smaller or narrower hands may find that they need to maintain a degree of tension to hold their hands "up" in position over the buttons. Large or wide hands will likely have less of a problem with this requirement to maintain hand position.

The MX Vertical is equipped with a top quality sensor capable of reading from 400 - 4000 DPI. Two nominal settings of 1000 and 1600 DPI can be adjusted anywhere within the range in 50 DPI increments. The top-mounted DPI button enables users to adjust the mouse as needed for basic or fine control movements. The scroll wheel has a rubber tire for grip and features distinct but soft detents. There are 4 programmable buttons (left, right, back, & forward).

The MX Vertical offers 3 connection options: Wired via the charging cord, 2.4Ghz Logitech Unifying Receiver with an operation distance up to 33 feet, and Bluetooth (Bluetooth Low Energy Technology required). The 270mAh Li-Po rechargeable battery can provide up to 4 months use on a single charge and offers a 1 minute Quick Charge that can provide up to 3 hours of use. Of course, individual usage may affect this. Using Logitech "FLOW" users are able to connect to and control up to 3 computing devices using a single mouse.

The "flatness" of the buttons on the MX Vertical prohibit the fingers from achieving a fully relaxed and naturally curved "position of function". This factor, combined with the almost slick surface on the buttons could lead users to try to "pinch" the mouse between the thumb and fingers in an attempt to achieve a better sensation of "control". In addition, to minimize the activation force on the buttons the fingertips need to be as close to the end of the buttons as possible. Those with large hands or very long fingers may be able to achieve this position but most users will find their fingertips falling short of this "optimum" position, resulting in a higher force being required for click activation.

The R-Go HE Ergonomic Wireless (Bluetooth on RGOHEWL model) Mouse from R-Go Tools rotates the hand upward and outward. This angled posture reduces strain on the tissues of the forearm when compared with the traditional pronated "palm down" position. In addition, because the hand is now elevated up and away from the surface, it is no longer possible to "plant" the heel of the hand in the manner that the traditional mouse position encourages. This virtually eliminates the potential for the development of RSI from repetitive or sustained wrist extension.

The R-Go HE Ergonomic Wireless (Bluetooth on RGOHEWL model) Mouse offers support for the hand and fingers, encouraging individuals to let their hand relax against the natural contours. Because hand sizes vary, the HE Ergonomic Wireless (Bluetooth on RGOHEWL model) Mouse is available in two sizes. Both sizes incorporate a flange so that the little finger is not left dragging along the desk surface. The Medium is sized to accommodate hand sizes up 7.3" in length, is available in both Left and Right hand versions, and is equipped with a 3-level sensor that reads from 800-1600 DPI. The Large is better suited for larger hands ranging from 6.9" - 7.7" in length. Large models are equipped with a 4-level sensor that can read from 500-2500 DPI for the Right hand model or 800-2400 DPI for the Left.

For portable convenience the R-Go HE Ergonomic Wireless (Bluetooth on RGOHEWL model) Mouse is rechargeable and has a battery-saving On/Off switch. Select models (see model descriptions) also features a "Break" indicator which can be activated to serve as a visual reminder to take regular breaks to reduce the risk of developing RSI. The Large models also include a storage slot for the wireless receiver.

The R-Go HE Ergonomic Mouse is also available in a standard Wired Model as well as the BREAK wired model which is also equipped with the "Break" indicator.
Note: When selecting the appropriate size of R-Go Mouse the hand should be measured from the tip of the middle finger to the first crease in the wrist.
