According to OSHA statistics from 2023, 33% of workplace injuries and illnesses are related to ergonomics. Despite a heightened awareness about ergonomics in recent years, workplace injuries continue to impact American workers. Carpal tunnel syndrome is a very common injury related to both the actual position of the wrist as well as the prolonged nature of that position during computer use.
What is Ergonomics?
Ergonomics refers to the study of the human body and how it interacts with and functions in its environment. The goal of workplace ergonomics is to ensure that body positioning, body movement, and the organization of the work environment itself reduces the risk of injury and promotes overall health and wellness. An ergonomically correct work environment not only prevents injuries but can contribute to employees being more productive and efficient. Occupational and physical therapists are trained to evaluate and make recommendations for improved ergonomics both at home and at work.
Why Does the Wrist Matter?
When you are using a computer mouse, your wrist should ideally be in no more than 20 degrees of extension. Most people are unaware, though, that the bend in your elbow should be greater than 90 degrees. In other words, your wrist should be below your elbow when you are seated in your office chair. This position allows adequate blood flow to your wrist during your workday while also reducing neck strain. Many times, we are unaware that we are compensating for poor positioning or discomfort in the lower arm and wrist by shrugging our shoulders and, subsequently, creating neck pain and injury.

Ergonomic Mice: Are They All Created Equal?
The shape and features of the computer mouse have evolved over the years. But many companies now make a vertical ergonomic mouse designed to allow the most natural wrist and hand position and minimize strain on the forearm, wrist, and fingers. In our Concussion Care Centre of Virginia office, both patients and staff have trialed the Seenda vertical mouse. It is extremely comfortable, but a bit large for smaller adult hands. Each company creates a vertical mouse with different specs, though. For example, Logitech specifically states that their Lift vertical mouse is good for small to medium-sized hands. Most vertical mice are designed to maintain the wrist and forearm in a more neutral “handshake” position and to keep the fingers in a slightly bent, comfortable position. But the height, width, and depth of each mouse can be different.

Conclusion
A vertical ergonomic mouse promotes a more neutral wrist and forearm position during computer use, helping to prevent both chronic use wrist injuries and neck pain. When you look to purchase one, though, you need to consider individual factors, such as your hand size. Set up your work area with proper elbow and wrist alignment and a vertical mouse. And then, enjoy the comfort of better wrist and forearm positioning throughout your workday!
