Researchers at Harvard University have found that the RollerMouse device significantly improved the posture of the hand, wrist, and shoulder compared to a conventional mouse, while performing tasks at a computer workstation. The study compared the RollerMouse to a conventional mouse, trackball and touchpad; it was determined that the RollerMouse had the greatest effect in reducing muscle effort in the forearm. Subjects also reported the RollerMouse to be easy to use with the least discomfort while performing tasks.
Abstract (taken from the report, presented at Applied Ergonomic Conference 2013, March 19, 2013):
The goal of this study was to evaluate the effect of different types of computer pointing devices and placements on posture and muscle activity of the hand and arm. A repeated measures laboratory study with 12 adults (6 males 6 females) was performed where participants completed two mouse-intensive tasks while using a generic mouse, a trackball, a stand-alone touchpad, and a roller-mouse. An optical motion analysis system and an electromyography system monitored right upper extremity postures and muscle activity respectively.
Roller-mouse associated with a more neutral hand posture (including lower inter-fingertip spread, finger extension) along with significantly lower forearm extensor muscle activity. Centrally located pointing devices (the touchpad and the roller-mouse) were associated with significantly more neutral shoulder postures and reduced ulnar deviation. In addition, significantly lower forearm extensor muscle activities were observed for these two devices.
Despite being unfamiliar with the device, users reported that the roller-mouse was not more difficult to use than the other devices. These results show that both device design and location illicit significantly different postures and forearm muscle activities during use; and suggest that hand posture metrics may be important when critically evaluating pointing devices and their association with musculoskeletal disorders.

Why Choose RollerMouse?
RollerMouse is a central pointing device for PC & Mac, which requires only very light movements on the roller bar, allowing the cursor to move around your computer screen with ease.
If you already suffer from wrist, arm, neck or shoulder pain when spending long periods of time working on your computer, it’s possible that RollerMouse will help alleviate your symptoms.
Centrally placed, and in front of your keyboard, RollerMouse is easy to reach, requires no gripping, and reduces the need for wearing and wasteful arm movements.
As well as encouraging a light touch, RollerMouse also invites load-sharing between both hands, and can alleviate RSI inflammation and pain that is often associated with problems such as Carpal Tunnel Syndrome, Tendonitis, De Quervains and many more common conditions.

Why Choose RollerMouse?
Even if you don’t have pre-existing pain, RollerMouse is the device that can help keep wear and strain injuries at bay. A relaxed way of working is key.
RollerMouse encourages good posture, and whether you are sitting or standing, avoids the need for awkward reaching and leaning, which is often the case with a traditional computer mouse.
As you become familiar with the controls of RollerMouse, it means you no longer need to reach, stretch, or twist to control the cursor on your computer. RollerMouse encourages you position your arms in a naturally relaxed position, in front of your body, rather than out to the side, removing strain to shoulders, arms and elbows.
There is no need for awkward gripping either, as the wide roller bar design allows for finger-tip control, in a way that is comfortable for you, also reducing strain on the fingers, hands and wrists.
With the option of integrated or extended wrist rests, you can find the RollerMouse that is perfect for your needs.

RollerMouse Red & Productivity
Designed for professionals who spend much of their working day in front of a computer, Contour’s revolutionary RollerMouse Red can help you develop a more efficient workflow, can be used with any software, and is designed to take away pain and strain often caused by traditional computer mice. Here we take a look at the benefits to creative professionals using music, photo and video apps.
Efficient Position A familiar workflow is critical to any type of creative design work. RollerMouse Red’s deliberately unconventional approach, puts cursor control right in front of your keyboard, and will help speed up workflow by removing the need to reach or find your standard mouse each time you need to move your computer cursor. Placing both hands close to your keyboard shortcuts also helps to reduce the time you take to complete your edits. Crucial seconds looking away from your screen to find your standard mouse add up to crucial hours lost, as those productivity deadlines approach.
Configure It! RollerMouse Red is plug & play on PC or Mac, and will work via USB without the need for additional drivers. While left & right click, double click, scroll wheel and copy & paste buttons are all pre-configured, using the optional drivers program will allow you to change what all the buttons do. Not only is RollerMouse Red a computer mouse which allows you to customise every button, but it also allows you to create different profiles to suite the software you’re using; automatically adjusting to your favourite keyboard shortcuts as you switch between apps such as Photoshop, Lightroom, Premiere Pro and more. For example, you can use the scroll wheel to move along your timeline, or apply automation to a single button using macros. Integrate your own keyboard shortcuts into RollerMouse Red to save yourself even more time!
Speedy Edits Capable of high cursor speeds, RollerMouse Red is also completely at home navigating across multiple monitors, even in relatively compact workstations, and requires no need for open desk space like a standard mouse. At the press of a button, adjustable cursor speeds also give you greater flexibility; fast speeds for timeline editing, but slower for those detailed image edits that you need to do. No more need to access computer settings to adapt to your current project.
Accurate Tracking RollerMouse Red is also highly accurate, making it perfect for complex edits that you need to do. With adjustability, up to 2400dpi, and with tracking measured within the roller-bar, rather than across a potentially uneven desk, RollerMouse Red provides a uniquely stable platform, allowing you to focus on where the cursor is going, rather than on where the computer mouse is placed. Keep your eyes on the screen, for more efficient editing.
Reduce Fatigue Whether you’re editing video or photos, being creative in CAD or crunching data for your latest software project, RollerMouse Red’s central positioning takes away awkward reaching and leaning associated with a standard computer mouse. Ambidextrous in design, RollerMouse Red allows for gentle fingertip control, meaning that you will be more relaxed as you work. As well as encouraging good posture, pain from common conditions such as RSI and Carpal Tunnel can be alleviated, as RollerMouse encourages you to adopt a relaxed hand and arm position. Designed in collaboration with top ergonomists and health & safety professionals, RollerMouse Red is a safer way to work on your computer.
Either at work or at home, we are spending more time in front of computers, and often develop habits that can cause stress, strain, and injury.
We’ve created 10 tips to help you become healthier, safer, and more productive at work.
- Listen to your body. Pay attention to the way you work, and how your body moves. People will have different ways of adjusting their body and behavior to avoid mouse injuries.
- Follow the 20-20-20 rule. Every twenty minutes, take a twenty second break and stare at something twenty feet away from you. This allows your eyes to readjust and reduces strain.
- Get it straight. Make sure to vary your seating position. Try to sit high up on the chair, so you put more weight on the legs than on the lumbar region. This helps keep your back straight and posture heightened.
- Don’t use force. Your mouse and keyboard are more sensitive than believed. Using a light touch will get the desired reactions and will decrease the potential for stress injuries.
- Make room. Make sure you have enough room on and under the desk so you can assume different sitting positions. A messy desk is also a source of stress and irritation, which can exacerbate mouse injuries.
- Keep moving. Take opportunities to stretch and do small exercises at your desk in order to maintain your strength and improve your cardiovascular conditioning throughout the day.
- Take a break. Take a five-minute break every hour. This helps the body relax and forces you to change your working position. You need a cup of coffee anyway.
- Get comfortable. Make sure you rest your arms in front of you and your fingers on the keyboard and mouse. Joint strain is often linked to tension in the arms and hands.
- Placement is key. Keep your chair in front of your monitor. Your monitor should be arm’s length away from you. Your keyboard and mouse should be directly in front of you within comfortable reach, with the keyboard lying level to your elbow.
- Designed for you. There are many alternatives to the traditional mouse that may help you reduce strain and prevent injury. Choose the best one for your body.
