Mouse wrist rests comparison and their relation with carpal tunnel syndrome (CTS) factors

TL;DRAbstract

Some studies have determined that wrist rests allow the most neutral wrist posture. Currently there is a huge variety of mouse wrist rests (MWR's) on the market. However, there does not seem to be any valid studies that address a comparison between the different types of wrist rests. The objective of this study was to compare four different mouse wrist rests, chosen as a representation of the ones on the market, and try to determine which mouse wrist rests characteristics are better to avoid CTS risk factors and more comfortable based on flexion/extension and ulnar/radial deviation angles measurements, anthropometric measurements, and perceived subject's strain and discomfort. A group of twenty-two Industrial Engineering Undergraduate Students (12 males and 10 females) participated in a laboratory study to compare the mouse wrist rests. The participants performed a 5 minute computerized task with each mouse wrist rest. Throughout the tests, wrist angles were measured with a twin axis e
