Many times we have been asked why the HandShoe Mouse does not have switch buttons under the thumb.
Well, there is a reason: the thumb is restricted in its motion possibilities. Repetitive thumb motions to activate such buttons could thus lead to inflammation. We have therefore decided not to incorporate any thumb buttons in the truly ergonomic HandShoe Mouse.
Do You Suffer From “Gamers Thumb”?
An already well known discomfort as a result of unnatural motions required to operate thumb buttons is the so called gamers thumb or SMS thumb.
Various studies have shown that repetitive motions of the thumb may lead to irritation.
Muscles control tendons which slide backwards and forwards through a tunnel.
To allow these tendons to move without friction the human body produces a slippery substance.
Excessive gripping and pinching, required to control these thumb buttons, may cause inflammation.
As a result this slippery substance deteriorates, and gets watery. The smooth sliding action of the tendons is then hampered.
This will cause pain, tenderness, swelling over the thumb side of the wrist and difficulty gripping.
