What is repetitive strain injury?

Repetitive strain injury, often shortened to RSI, is a broad term used to describe pain or discomfort caused by repeated movements or overuse of a part of the body. It most commonly affects the hands, wrists, forearms, elbows, shoulders and neck.

RSI is not one single condition. Instead, it covers a range of problems that can develop when muscles, tendons or nerves are strained over time.

Common causes of RSI

RSI can happen when the same action is repeated again and again, especially if there is little rest in between. It is often linked to jobs or activities that involve typing, using a mouse, working on a production line, playing musical instruments or using hand tools.

Poor posture, awkward working positions and poorly set-up desks can make the risk higher. Doing a task too forcefully or for long periods without breaks can also contribute.

It can also affect people outside work. Gardening, gaming, sewing and sports that involve repeated movements may trigger symptoms in some people.

Symptoms to look out for

The symptoms of RSI can vary depending on the area affected. Common signs include aching, stiffness, throbbing, tingling, numbness or weakness.

Some people notice swelling, tenderness or a burning sensation. Symptoms may start gradually and become more noticeable during or after activity.

In some cases, the discomfort can spread to other areas or become worse over time if the cause is not addressed.

Who can be affected?

Anyone who repeats the same movements regularly can develop RSI. It is often seen in office workers, factory staff, warehouse workers, musicians and people who spend a lot of time using computers or handheld devices.

Age does not protect against it, and even people who are fit and active can be affected. The main risk is usually the combination of repetition, force and lack of recovery time.

How RSI is managed

If you think you may have RSI, it is sensible to reduce or stop the activity that is causing pain where possible. Rest, gentle movement and improving posture may help in mild cases.

At work, adjustments such as better chair height, screen position, keyboard setup and regular breaks can make a difference. A GP or physiotherapist can advise on treatment if symptoms continue.

Early action is important, as ignoring the symptoms may make them harder to treat. If pain is persistent, severe or affecting daily activities, it is worth seeking medical advice.

Can RSI be prevented?

RSI may not always be avoidable, but the risk can often be reduced. Taking regular breaks, varying tasks and keeping a relaxed posture are useful steps.

It also helps to make sure your workstation is set up properly and that you do not grip tools or devices too tightly. Small changes made early can help prevent pain from developing or worsening.
