Mouse arm and repetitive strain injuries
But what exactly is mouse arm?
Mouse arm is a repetitive strain injury (RSI). If you feel pains in your shoulder, forearm, hand, or wrists when working at your computer, you probably suffer from a mouse arm. The common denominator for mouse arm – a term covering different ailments – is that the pains typically appear when working in front of a computer using a traditional mouse or keyboard. Usually, you can sense the pain in the areas mentioned above.
“Mouse arm” is a term coined by the public, as it is easier to use than carpal tunnel syndrome (CTS) or De Quervains tenosynovitis. Two of the many sufferings mouse arm refers to. Besides, the mouse arm is easy to connect to one of the computer mouse’s key triggers. More on that later.
Both CTS and De Quervains syndrome are ailments often caused by strains and congestion, why these are by far the most active trigger for mouse arms.
Often it is followed by inflammation in either muscles or tendons, where the tissue becomes irritated, causing it to swell and become sore. However, the mouse arm can also come from a pinched nerve or a severe case of myositis. These are local muscle pains that are not considered an actual injury but where the muscles have contracted.

How does the RSI / mouse arm occur?
For most people, a mouse arm is an ailment that happens with static computer work.
Computer-related causes for mouse arm:
– Long hours working in front of a computer with a traditional mouse
– Repetitive computer work
– Precision work using a conventional mouse
– Not resting your elbows on the desk when working
– Too small or the wrong mouse
– Using too much force when clicking or typing
A mouse arm often appears when working in front of a computer because it is not a natural position. Additionally, you tend to sit in it for many hours in a row. The many repetitive motions – such as clicking or typing – strains both muscles and tendons. Doing this for longer allows for high amounts of stress to nerves and tissue, why damage to these typically follows. As such, it is essential to be careful and change your habits and working positions.
Everything is not the computers’ fault
