To assess the post operative activities (Ambulation, Deep breathing exercises, circulatory exercises, abdominal exercises and daily activities) among experimental and control group after pre operative teaching on early ambulation. To evaluate the effectiveness of computer–assisted pre operative teaching in reduction of post operative complications by early ambulation in experimental and control group.  Sixty samples (30 in experimental and control group) were selected by convenient sampling technique from the male and female surgical ward, post operative annex ward .The researcher used post test only design Interview schedule is used to collect the demographic information, Observational checklist deals with post operative activities and, Assessment of physiological parameters, used as an instrument to assess the effectiveness of computer assisted pre operative teaching in reduction of post operative complication among patient undergoing abdominal surgery. The finding of the study shows that ,the mean score for the 3rd day was 37.74(75.54%) with SD of 7.79 in experimental group, 18.07(36.14%) with SD of 1.82 in control group and their percentage of gain score difference is 39.40%. Since the percentage gain score difference is increasing it shows that computer assisted teaching has effectiveness in experimental than control group. There is no statistically significant difference in reduction of post operative complications in both groups. The major conclusion drawn from this present study is that there is increasing level of activity occurs in the experimental group by means of computer assisted pre operative teaching. There is significant difference between the effectiveness of computer assisted pre operative teaching on early ambulation between experimental and control group.
