Repetitive strain injuries (RSI) are both common and serious. They have serious leng-term economic effects on the productivity of both individuals and nations.

Computer use is a common cause of RSIs - as is playing musical instruments.

Many RSIs which are related to computer use appear to arise as a result of damaged tendons executing a sawing action - resulting in inflammation and pain in surrounding tissues.

There are other common muscular disorders associated with computer use which also arise as a result of computer use - including muscular indurations in the shoulder - as a result of continuous strain in muscles stabilising the head and arms.

Many RSIs often heal gradually over time - but healing can be a time-consuming process - and sufferers often find that even minor levels of activity aggravate the disorder - and reduce the rate of recovery.

Recovery often takes years in young healthy individuals who have the opportunity to rest. Age, or loss of control over ones working environment may cause the process to take longer still - and there are some who never recover.


Subsynovial connective tissue injuries may be behind many cases of RSI. Details are here.

RSI - quackery

Since RSI is common and some of the victims are not short of money, it appears that RSI has attracted a substantial volume of therapists eager to cash in - and there is a large volume of RSI quackery.
