"Could The Threat Of RSI Be A Shot In The Arm For Ergonomic Mouse Maker Contour?"
YOUR PAIN HAS A REASON. Understand the cause, Then fix what hurts.

Carpal tunnel–type wrist pain
What's going on: A side-placed mouse makes you reach and twist, increasing wrist deviation and tendon load, common carpal tunnel type triggers.
Try this: Center your cursor with RollerMouse. Hands stay in front, wrists stay more neutral, and you can switch hands anytime to share the load.
What science says: A peer-reviewed study in Applied Ergonomics found that a centrally placed RollerMouse produced more neutral shoulder and wrist postures and lower forearm extensor muscle activity than a conventional mouse or trackball.

Repetitive Strain Injury (RSI) from your mouse
What’s going on: Reaching and repeating the same moves all day builds strain in your hands, wrists, and forearms.
Try this: Low‑force roller control and built‑in shortcuts cut extra clicks and micro‑reaches. Because RollerMouse is centered, you can share the work between both hands.
What science says: In the same lab study, Applied Ergonomics, a centered RollerMouse produced more neutral upper-limb postures and lower forearm extensor activity vs. a conventional mouse or trackball.

Shoulder & neck tension from side‑reach
What’s going on: Parking a mouse to the right or left abducts your shoulder. Over time that can feel like a dull, constant pull.
Try this: Center it with a RollerMouse. Elbows stay close and our cushioned palm supports let your hands rest lightly instead of hovering.
What Science says: Lab data in Applied Ergonomics found that centering a RollerMouse, shoulders stay closer to your body (less abduction and flexion) and forearm extensor effort drops vs. a conventional side mouse or trackball, reducing biomechanical risk factors linked to discomfort.

Why Go Ergonomics?
If your shoulders, wrists, or forearms ache after a day with a regular mouse, you’re not imagining it.
A research team in digital pathology ran a laboratory study published in Revista Española de Patología¹ comparing 10 different pointing devices, including RollerMouse, vertical and conventional mice.
While people did the same on-screen task, they measured upper-arm and forearm muscle effort using surface electromyography.
They found two big things:
RollerMouse required the least effort. Less muscle effort means less day-to-day strain, the sympthoms that often feels like aching or fatigue.
Hand position matters. RollerMouse’s centered, palm-supported design created the most neutral posture. Out of 10 devices, it demanded the least overall muscle effort, helping reduce strain that drives discomfort.
Central pointing = a more efficient way to work
Our patented line of RollerMouse revolutionizes how we interact with computers by sitting directly in front of the keyboard. The result: better ergonomics and a healthier workflow:
- Eliminating static postures and encouraging posture variation.
- Reducing gripping and straining required to control the cursor.
- Keeping elbows in at your side and arms forward to create a neutral posture.
- Reducing contact stress and pivoting of the wrist, a major contributor to carpal tunnel syndrome.
