Therefore many people arenow working with computer for longer hours of time. There is no doubt that thisincorporation of computer has helped users a lot but it also brings problems tothe users.

Five hundredand thirty one (531) questionnaires were personally administered to differentcategories of people that use computer in various works of life, ranging frombanking sector, civil service, educational sector, health sector to privatesector. The distribution cut across different professions. A statisticalanalysis was conducted on the data obtained using frequency distribution,Pearson Correlation and Linear Regression. The result obtained showed that94.3% of the respondents suffered pain from one or more parts of the body.86.8% of the respondents suffered from eyestrain, 63.9% suffered from low backpain, 67.4% with wrist pain, 64.7% finger pain while the least suffered painwas foot pain which only 19% responded positively to it. There are significantrelationships between duration of computer usage, type of chair used, type andsize of monitor used and the incidence of RSI. RSI modeled was formulatedthrough linear regression which showed that a unit change in computer willresult in corresponding 1.76 unit increases in RSI and a unit change inergonomic deficiency will also result in corresponding 0.66 increases in RSI.The existence of RSI was established and it was discovered that the more timespent on the computer system, the more the proximity of having strain or painin one or more part(s) of the body.
