What kinds of activity cause RSI/OOS?
RSI spans many industries and occupations, including journalists, butchers, hairdressers, musicians, carpenters and cleaners. The highest incidence of RSI occurs in meatworkers. RSI can be also caused by leisure activities such as golf, knitting, video games and playing a musical instrument (Arndt, 1986). In the past when most highly repetitive and/or forceful physical work was done by poorly-paid manual workers. However, now that computers are widely used by white collar workers and managers, RSI is common across all levels of the workforce. Comcare’s 1997 report states that 80% of sales people, 81% of clerks, 86% of professionals and 78% of managers reported mild or severe OOS.
