It’s easy to blame an achy neck and stiff shoulder on bad posture. But on many desks, experts agree, the quiet culprit is your mouse.
“There are a lot of delicate body parts involved in mousing,” explains Cameron Stiehl, a San Francisco-based ergonomic assessment specialist. “When you’re at the computer for hours at a time, having a mouse that doesn’t fit properly or is positioned incorrectly can cause soft-tissue injuries in the fingers, wrists, hands, elbows and even in the shoulder.” Countless ergonomic mouse models promise improvement. If you’re ready for a level up, here are four mice that will give you a hand.
| 1 | Semi-vertical mice like the Logitech MX Master 3S have a 30 to 45-degree slant, which can help reduce stress on the forearm muscles. It can help relieve discomfort from epicondylitis (or ‘tennis elbow’) or help a sore wrist. At 141 grams, the MX Master 3S is a bit heavy but is designed to be especially responsive so that you needn’t move it too much. You can also custom-program the functions of the mouse’s seven buttons and two scroll wheels, letting you avoid certain repetitive motions that can cause injuries. $100, Logitech. com |
| 2 | Look past their uncanny resemblance to Kubrick’s HAL 9000. Trackball mice can be particularly helpful for treating shoulder discomfort by limiting most of your mousing movement to the fingers and wrist. For the most natural motion, Stiehl suggests the Kensington Orbit Trackball. It has both the namespace feature for moving your cursor with little effort and a ring-style scroll wheel encircling it. Unlike traditional scrollers, you use it like a dial. This, Stiehl says, makes the mouse “especially good for people who have issues like trigger finger” (when bending your digits causes them to painfully click and pop). The Orbit also takes the ergonomics a step further, with an included, detachable wrist rest. $50, Kensington. com |
| 3 | A vertical mouse lets you position your hand not flat but tilted sideways as if you’re shaking hands with the device. This position, reduces wrist and forearm movement and can be soothing. The Logitech Lift version’s small footprint and light weight (125 grams) make it a good fit for small hands. “It’s not a long vertical, so I think it can be very comfortable if it fits the hand,” said Stiehl. Six buttons allow for control customization, and it comes in three colors (including a very cute rose), and is made of mostly recycled material. $70, Logitech. com |
| 4 | Working away from your desk doesn’t mean you can’t cast an eye toward ergonomics. The Lenovo Go Wireless Vertical Mouse is a compact vertical mouse, powered by a single replaceable AA battery, which the manufacture r promises will last a year. It also features a handsome cork thumb divot. But the selling point is its smaller footprint, which makes it easy to pack with your laptop. $50, Lenovo. com |
