Contour Science

A global problem. A daily habit.

We start where the research starts: with the size of the problem. Then we zoom in on your desk, your mouse and your arm, and show what changes when you switch to Contour, from the office desk to the point of care.

  1. The world 1.71 billion

    Approximately 1.71 billion people have musculoskeletal conditions worldwide.1

    WHO

01 · The problem

Neck and shoulders feel it first.

In a study of 560 office workers, more than half reported neck or shoulder symptoms over 12 months, and nearly 1 in 3 wrist or hand symptoms.5

Office workers reporting symptoms over 12 months, in one study of 560 office workers, as reported in an independent systematic review (de Alencar et al., 2025).

Hours at the computer

More than 4 hours a day on the computer or mouse is linked to a 25% higher risk of new arm, neck and shoulder complaints.6

IndependentA meta-analysis of 4 cohort studies of office workers, followed for 1–2 years (Rijal et al., 2026).

Mouse or keyboard

Hand, arm and shoulder problems are more closely linked to mouse time than to keyboard time.7

Earlier research (Gerr et al. 2004; IJmker et al. 2007), as cited in a peer-reviewed lab study (Lin et al., 2015).

Mouse arm, RSI, carpal tunnel: what do the names mean?

Mouse arm, RSI and carpal tunnel syndrome are different names for a family of overuse conditions of the hand, wrist, forearm and shoulder; the more hours a day someone spends on the mouse, the more likely they are to report hand and arm symptoms.8

Strain injury symptoms may develop when you repeat the same movement over time or when part of your body does not have enough time to recover between activities.9 For example:

  • Repeated mouse gripping
  • Prolonged keyboard or mouse use
  • Too few breaks between repeated tasks

If you have symptoms, talk to a doctor or physical therapist. They can tell you what’s going on and what will help.

02 · Your day

Once a minute. 600 times a day. 140,000 times a year.

That’s how often you grip your mouse.10 Our centered pointing devices have nothing to grip.

Every trip to the mouse: hand off the keyboard, arm out to the side, and back. Illustration, created with AI from our own photography.

With a mouse at the side, your arm is out, away from your body, every time.14

A mouse at the side typically holds your arm out and forward and bends your wrist back and outward. Prolonged use of a standard mouse is linked to musculoskeletal symptoms.15

An independent systematic review of 17 controlled trials of alternative mouse designs, citing earlier research (Radwan et al., 2018).

Lifting the arm out to the side has been identified as a risk factor for neck and shoulder problems.16

Earlier research (Cook, Burgess-Limerick and Papalia, 2004), as cited in a peer-reviewed lab study (Kumar and Kumar, 2008).

Researchers consider how much you use the mouse,17 and how hard you grip it,18 as possible risk factors for hand and arm disorders.

An independent systematic review (de Alencar et al., 2025) and an independent workplace study of mouse use (Johnson et al., 2000).

03 · What changes

RollerMouse gives your shoulder a break.19

Keep your upper arms close to your body, not reaching forward or to the sides: that’s standard workstation advice.20 Our centered pointing devices sit in front of your keyboard, so it’s built in.

Seen from above: two hands on a keyboard, with RollerMouse in front of it, centered between them.

Less muscle work in the pointing arm.

Five lab studies

Consistent across five lab studies: RollerMouse needed less muscle activity in the pointing arm than a traditional mouse.21–25

Two of the five are independent; one was partly funded by free product units from Contour.

RollerMouse Red Plus vs nine other devices

Ranked #1 of 10 pointing devices for lowest muscle activity.24

The other nine included a conventional mouse, a vertical mouse, trackballs and a touchpad.

IndependentA standardized lab study of 6 adults doing digital pathology tasks (Alcaraz-Mateos et al., 2022). Devices were ranked, not compared pair by pair.

Your arm stays close.

Shoulder posture · RollerMouse

Half the shoulder lift. In a lab study, people raised their upper arm about half as much with RollerMouse as with a mouse at the side: 7° vs 14° out to the side and 12° vs 25° forward.27

People feel the difference.

Wrist strain, as rated · RollerMouse

People felt less than half the wrist strain with RollerMouse than with a traditional mouse.29

A lab study of 24 adults new to RollerMouse, who used it and a traditional mouse in turn for nearly 4 hours (Kluth and Keller, 2015).

Comfort at work · RollerMouse

Nearly 9 in 10 surveyed customers said RollerMouse increased their comfort or well-being at work.30

Commissioned by ContourAn online survey of 233 RollerMouse customers in Denmark, Sweden and Norway, April 2024. Self-reported.

Shoulder comfort · Contour Touch

4 in 5 users said their shoulder felt better after 4 weeks with Contour Touch; none felt worse.31

19 better or much better · 5 the same · 0 worse

Our own studyOur own 4-week study of 24 office workers with shoulder discomfort. No control group; devices provided free.

Comfort score · UniMouse

Six vertical mice. Twenty hands. One favorite: UniMouse got the highest comfort score of the six, with top-group pointing speed.32

Differences within the top group were not statistically significant.

Our own testOur own lab test: 20 participants did standard pointing tasks with six vertical mice and rated comfort, effort and fatigue (Cappelletto, 2025). Commissioned by Contour; not externally peer-reviewed.

Getting used to it · Contour Touch

Very easy to adopt: after 4 weeks, more than half of users gave Contour Touch top marks for ease of adaptation, and 9 in 10 rated it 4 or 5 out of 5.33

13 gave 5 out of 5 · 8 gave 4 · 3 gave 3 or less

04 · Medical keyboards and mice

In healthcare, every second counts, and so does every surface.

Care teams touch the keyboard and mouse between patients and during procedures. Here is what independent research found on those surfaces, and how we design ours to be wiped.

A hospital ward with a computer workstation on wheels between the beds.

Touched constantly. Often missed.

Operating room · touches

The keyboard and mouse are among the most-touched surfaces in the operating room – about 25 touches per operation in a 2026 study.34,35

About 25 touches per operation

IndependentOne hospital in China, 20 operations observed (Huang et al., American Journal of Infection Control, 2026). A US study also found the mouse among the five most-touched operating-room items (Link et al., 2016).

Between-case cleaning

In that study, the most-touched item wasn’t on the operating room’s between-case cleaning checklist.34

IndependentSame study. The authors added the keyboard and mouse to the checklist during the study.

After one operation

In a 2026 hospital study, almost 2 in 3 operating-room keyboards and mice carried bacteria after a single operation.34

13 of 20 samples

IndependentSame study. Swabs taken after the first case of the day; ‘bacteria’ means any colony, species not identified.

75 studies

Hospital keyboards and mice are often contaminated: in a review of 75 studies, most of those that reported an overall rate found 80–100% of devices contaminated. Several disinfection methods reduced it, though results varied.36

A systematic review of 75 studies and 2,804 devices in healthcare settings (Ide et al., BMJ Open, 2019).

Wiping works. Flat surfaces wipe best.

Wiped vs not cleaned

In the same study, keyboards and mice wiped with disinfectant between cases had a median of zero bacterial colonies, against 1.25 on stations that weren’t cleaned.37

IndependentSame 2026 study: 10 wiped samples compared with 10 from stations that weren’t cleaned. Use of a neutralizer not reported.

Surface design

In laboratory and ICU testing, bacteria were found to be most easily removed from a flat, silicone-coated surface.38

Laboratory transfer tests and a controlled ICU trial of eight cleanable keyboards and standard keyboards (Wilson et al., American Journal of Infection Control, 2008).

Contour QuickClean Medical Keyboard C8112

Easy to wipe. Easy to type on.

Contour medical keyboards and mice can be wipe-disinfected between cases, so care teams can include them in their cleaning routine, as their own protocols require.

  • Clean without unpluggingCleanFunction pauses the keys, so you can wipe it down without unplugging.39
  • Fewer places for germs to hideFlat, sealed and gap-free, with fewer places for germs to hide. Sealed to IP68.39
  • Made for wipe disinfectionDesigned for wipe disinfection in line with the CDC guideline40 and compatible with VAH-listed disinfectants.
  • Familiar typing feelWe designed it to feel like a familiar keyboard to type on.
