S. A. The results of this widespread use of keyboards is that, over time, individuals who work in suboptimal wrist postures usually tend to develop a variety of musculoskeletal accidents. This is why we’ve seen a rise within the variety of accidents and a rising consciousness of the significance of excellent ergonomic design.

Non-standard Layout And Special-use Types
The second consideration is the angle of the keyboard relative to the angle of the wrist.
