Probable Risks
While using a traditional keyboard, you may have to bend your wrists sideways to reach all the keys. When you extend the legs on the back of the keyboard, you tend to bend your wrist upward causing a keyboard tilt.
The keyboards of the laptop computers that are comparatively smaller than the normal ones also force the user to sit in awkward positions (Laptop Ergonomic Tips for Keyboard). This in turn leads to contact stress to the tendon sheath and tendons that must move within the wrist during repetitive keying.
Feasible Solutions
-
Adjust the height of the Ergonomic Keyboard or chair to attain a neutral wrist posture thus reducing the awkward wrist angles.
-
The user may even elevate the back or front of Ergonomic Keyboard to achieve a neutral wrist posture. Normally, if the user is sitting in a position lower than that of the keyboard, a slight elevation made to the back of the Ergonomic Keyboard would help maintain a neutral wrist.
-
Similarly, if the user is typing with the Ergonomic Keyboard in a lower position, raising the front of the Ergonomic Keyboard may help maintain neutral wrist postures. If the Ergonomic Keyboard feet tend to increase the bending of the wrist, do not use it.
- You can sit with neutral wrist postures by taking into account alternative Ergonomic Keyboard. These can be provided on a case-by-case basis. It takes time to get used to such mechanisms.
Though alternative Ergonomic Keyboard help the users to maintain neutral wrist postures, studies have not yet provided enough information regarding its capability to avoid discomfort and injury.
- The size of the Ergonomic Keyboard and spacing of the keys should be of appropriate size to suit majority of the customers. The recommended spacing between the centers of two keys horizontally is 0.71-0.75 inches (18-19 mm) and vertically is 0.71-0.82 inches (18-21 mm).
Ergonomic Keyboard Recipe
- You can maintain neutral wrist postures by using split type of Ergonomic Keyboard.
- Ergonomic Keyboard with more adjustability options are often better than the others to maintain neutral wrist postures. There are Ergonomic Keyboards with adjustable feet that can accommodate a wider range of Keyboard Ergonomic positions and angles. Ergonomic Keyboard with adjustable feet on the front as well as the back will further aid adjustments.
- Ensure that the cord connecting the Ergonomic Keyboard and the CPU has ample length to let the user place both these components in a variety of convenient positions in the workstation. The recommended cord length is around six feet.
- Consider an Ergonomic Keyboard without a 10-key keypad if the task does not require one. If the task does require one occasionally, an Ergonomic Keyboard with a separate 10-key keypad may be appropriate. Ergonomic Keyboard without keypads allow the user to place the mouse closer to the Ergonomic Keyboard.
- If you prefer to work with the Ergonomic Keyboard tray, ensure that the size and shape of the keyboard matches with that of the tray.
- It is always better to buy separate wrist rests than going for Ergonomic Keyboard with built-in wrist rest.
- If you have to work for prolonged hours with Ergonomic Keyboard, detach them from the display screen. Do not use laptop for long hours of typing jobs.
Ergonomic Keyboard Tray Recipe
- The width and depth of the Ergonomic Keyboard trays should be large enough to accommodate the keyboard and any secondary devices, such as a mouse.
- The minimum vertical adjustment range (for a sitting position) should be 22 inches to 28 inches from the floor, if you are working in the sitting position using the Ergonomic Keyboard tray.
- Ensure that your Ergonomic Keyboard tray has adjustment mechanisms that lock into position without having to turn knobs. These are frequently over tightened, which can lead to stripped threads, or they may be difficult for some users to loosen.
