An experimental study was conducted to assess the effectiveness of progressive muscle relaxation technique on pain perception among patients who are subjected to abdominal surgery. Experimental repeated measures design was chosen for this study. With a total of 40 male and female patients, 20 patients were considered as experimental group and 20 as control group. The technique that was adopted for this study was random sampling method. Progressive muscle relaxation was given as intervention for experimental group and only observation was made in the control group. Collected data were analyzed by descriptive and inferential statistics. Study results showed that mean pain score for the first day morning in pretest was 6.70 with standard deviation 0.92 and the post test mean was 6.30 with standard deviation 1.03. Thus the mean pain score (6.3) on third post operative day was less compared to mean pain score (6.7) on the first post operative day. From the above mentioned statistical values it is observed that there is a high statistical significance in pain perception at P<0.001 and there were no changes were in level of pain in control group. This clearly indicates that progressive muscle relaxation technique has influence on pain perception in the experimental group.
