Whether you’re typing your 100-page thesis, a report for work, or just doing everyday email and word processing, the repetitive strain of typing on a traditional computer keyboard can cause carpal tunnel syndrome, tennis elbow, and other repetitive strain injuries.
Designers have created special keyboards that are more comfortable and easier to use, based on how you type and how you are built. They’re designed for comfort and convenience with many people finding them to be a helpful alternative to traditional 128-key keyboards. But buyer beware, there are many keyboards on the market that are labeled as ergonomic that may not actually provide the benefits they promise.
In this article, we’ll introduce you to the many different types of ergonomic keyboards for general typing.
Traditional keyboards are rectangular in shape and often have adjustable feet allowing you to tilt the keyboard towards yourself. On a standard keyboard there are 128 physical keys that can be broken down into 8 different types of keys. There are 3 types that are important to consider when choosing what keyboard is right for you
Most people end up aligning themselves so that they are centered on the alphanumeric keys. This often results in the keyboard extending out beyond the shoulder width of the user on the right side. Most people have the mouse positioned on the right side and thus demonstrate excessive external shoulder rotation when accessing their mouse. This can result in rotator cuff tendonitis and pinched nerves which often have symptoms that radiate down through the arm into the hands and fingers. It also has the potential to lead to awkward wrist postures and movements when mousing which can contribute to carpal tunnel symptoms.
The straight layout of the keyboard can also create awkward wrist postures. Generally individuals who type with the home row method, meaning people who rest their hands on the middle row of alphabet keys: a-s-d-f and j-k-l-; respectively, are more likely to demonstrate ulnar deviation (slight side bend toward the pinky) at their wrist. This can result in pain or discomfort along the wrist joint.
Ergonomic keyboards help you maintain a more neutral typing and mousing posture, avoiding too much extra stress on your body. These alternative keyboards can come in a variety of different configurations each to address specific concerns. This makes it important to choose the right one for you based on your specific needs.

Retains a single-piece design with a space in the middle for angled alphanumeric keys. Many keyboards marketed as ergonomic will be of this style but will still maintain the navigation keys and number pad found on traditional keyboards. Look for models with detached numeric keypads for improved ergonomics. The Microsoft Sculpt Ergonomic Keyboard has long been a favorite of the MoveSafe consultants however Microsoft has recently pulled out of the keyboard and mouse market. The Lenevo Go Keyboard has been the closest alternative to become available, but keep any eye out for a Logitech option in the future.
Ergonomic keyboards offer improved comfort and may help prevent typing-related injuries in the long run. While they may have a higher upfront cost, they are a worthwhile investment in your health and productivity. By choosing the right alternative keyboard for your needs, you can enjoy a more comfortable typing experience and reduce the risk of repetitive strain injuries. Are ergonomic keyboards worth it? Absolutely. Invest in your health and upgrade to an ergonomic keyboard.
Having an ergonomic keyboard is still only part of the solution to reduce the risk of musculoskeletal injuries.
