What is repetitive strain injury?
Repetitive strain injury, or RSI, relates to the overuse or over-activity of muscles and tendons in the body, particularly the hands, wrists, arms, shoulders, back and neck. There are two types of RSI. Type 1 RSI is diagnosable from the symptoms listed below; however, Type 2 RSI is not recognisable from the symptoms and is often referred to as non-specific pain syndrome.
Symptoms of repetitive strain injury
Symptoms can vary, but generally include:
- Pain or tenderness in muscles or joints
- Tingling or numbness
What causes RSI?
Although the exact cause is not known, certain things are thought to increase the risk of RSI, including:
- Doing a repetitive activity, over a long period, without rest
- Activities that involves force, such as heavy lifting
- Poor posture
- Working in an awkward position
- Cold temperatures
How to treat RSI
The most important step of treating RSI is identifying its causer. Symptoms can be relieved with:
- Ice pack or cooling agent, such as Physicool
- Steroid injections
Physicool’s reusable cooling bandage is often used by those suffering from RSI. Apply the bandage to the injured area to receive instant relief from the pain and swelling.Physicool is a unique cotton bandage impregnated with a patented liquid which draws heat away from the affected tissues by rapid evaporation. While the deep tissues are being cooled, the simultaneous compression effects of Physicool modify the inflammatory response to soft tissue damage which helps promote healing.
