Design

edit

Wrist rests can be made frommemory foam,gel,leather, orhardwood,the most common being memory foam rests.[4]Memory foam rests retain impressions for longer, while gel rests quickly return to their original shape.[4]Gel rests provide more cooling.[4]Some computer keyboards come with a wrist rest included.[5]

Beyond the typical wrist rest designs, some companies have created variations that add extra functionality or aesthetics. For example, alaptopwith a foldable wrist rest,[6]agame padwith a stylizedPokémonwrist rest,[7]or a wrist rest that also functions as a mouse.[8]

Ergonomic use

edit
The wrist can be strained by the increased angle when typing without a rest.

There are mixed opinions on whether wrist rests for computer keyboards are a benefit toergonomics.[2]

The main benefit of using a wrist rest is increased comfort, especially for those using keyboards over long periods.[1][4]Usage of a wrist rest can alleviate tension can take away pressure from the neck, shoulders and arms.[2]Using a keyboard without a wrist rest may increase the bending angle of the wrists, causing strain and tendon irritation.[1]

Prolonged contact between the wrists and the rest may causecarpal tunnel syndromeortenosynovitis.[2]Resting the wrists on a rest while typing may prevent motion of the wrist, causing issues.[1]

To mitigate potential problems, theOccupational Safety and Health Administration(OSHA) recommends the hands to be elevated above the rest while typing.[1]While not typing, the rest should contact the hand'spalm/heel,not the wrist.[1]As well, they recommend for the wrist rest's slope and height to match the front of the keyboard, and for the rest to be soft, with a depth of at least 3.8 centimetres (1.5 in).[1]

Scientific research

edit

A 2004 study published inElsevierdescribed the literature on the efficacy of wrist rests as "limited, inconclusive, and contradictory".[3]Some studies have concluded that wrist rests reduce strain while others have concluded rests cause more strain.[3]A 2018 study looked at asample sizeof 25 during prolonged typing.[9]They found wrist rests to reduce fatigue in thebiceps brachiimuscle but have no effect on the uppertrapeziusmuscle.[9]
